Olbrecht Model Capacity- build up conditioning Aerobic Cap- build up VO2max o Low to moderate intensities with faster “spices” Anaerobic Capacity- build max pyruvate (lactate ) production o Short, fast (near max) intervals, full rest High mileage/low intensity temporarily reduces Anaerobic Cap but returns within 3-5wks Too low AnCap- come closer to max capacities at subjectively easy pace. See no warning signs of fatigue and therefore swim to fast, further decreasing Anaer Cap, and overtraining As Anaerobic Capacity increases, it will be increasingly difficult to build up Aerobic Power Higher the Anaerobic Cap, the more Aerobic Power workouts needed to peak Anaerobicly strong athletes have to swim at a lower % of best time to reach a particular lactate value. While Anaerobicly weak athletes have to swim at a higher % of best time to reach a particular lactate value Power- fine tuning, maximize utilization of conditioning o Aerobic power- maximize use of the VO2max (%VO2max) at a speed, increase % of VO2max that can be maintained during distance exercise 1-2x per week max during pre comp. results can be seen after only 3 weeks 4-6 weeks needed to maximize for distance swimmers •

Anaerobic power- %VLamax- maximize use of the maximal lactate production capacity Used to toughen runner against acidosis Adaptation comes quickly (2 weeks). Sprinters need only 3-5 weeks to maximize Effects noticed after 10-17 days Done as fast as possible with little rest or longer runs at max speeds w/ full rest Drives down both Anaerobic Cap and Aerobic cap Total distance for 1 set (600-800m) with total max of 2000m Aerobic Power= the Higher Aer Cap, the higher Aer Power is the higher Anaer Cap, the lower Aer power Rest during workout: o passive= Increased buffering o Active= Increased clearance To inhibit Anaerobic development, follow Anaerobic work with long extensive run Stronger Aerobic system means more Lactate removed during exercise, thus longer it takes for pH to to drop to low level. So stronger Aerobic system system allows Anaer system to operate at high level for a longer time. Anaerobic Power= Increased if run fast repeat w/ high lactate exhaustive interval set Improve Lactate Threshold by: Lactate utilization increase(better Oxygen delivery or increase mitochondria) o Decrease Pyruvate production (lower Anaer cap or more reliance on fat) o o Increase Lactate Clearance (Oxygen delivery, uptake) Super compensation Inflammation, overtraining, and mental stress reduce super compensation o Time needed for Super compensation depends on how well rested and o conditioning (both decrease time needed) and due to duration of biological processes (protein and enzyme reconstruction and glycogen replacement) Fast adaptation (2 weeks) and stabilization phase (3-4wks) of adaptation o o More morphological (structural) adaptations required, the more time it takes to improve the capacity Aerobic Power spice during base= max of 2,000m of running (ex: 6x400 at 2mi to 5k pace) Anaerobic Power- Total Running Volume 500m-1000m w/ 1.5km max o Ex: 2x (4x200 w/ 30sec and 10-20min rest) It decreases Aerobic and Anaerobic Capacity o Overdose breaks down Anaerobic Power o o Number of training units per week, not weekly volume of Anaerobic workouts determines increase in Anaerobic condition Accumulation of pyruvate indirectly slows slows activity of glycolysis.

Acidosis depends greatly on rate of pyruvate conversion to lactate because at high rate, buffer capacity is overwhelmed Possible reason for an excess of pyruvate that causes a high conversion to lactate Pyruvate is not sufficiently eliminated by oxidation o o The production of pyruvate is very high Thus a high capacity to produce pyruvate is of no benefit if capacity of aerobic system to use it is too low Top distance swimmers need 4-6 weeks of specific work to reach aerobic power Top sprinters take 3-5 weeks of specific Anaerobic power workouts to reach optimal Anaerobic power However if 3 weeks of straight Anaerobic Power is done, basic endurance o decreases. o Prevent by either 2 weeks Anaerobic, 1-2 days regeneration, 3-5 days Aerobic Capacity, 1-2 day regeneration, 2 weeks Anaerobic power OR 2 weeks Anaerobic Power, 10 days max of Aerobic Refresh, 10-14 day o Anaerobic Power With time off lose first Aerobic power then Aerobic Cap, strength, speed HR useful to see whether organism can globally deal with stress load Change in Anaerobic Cap has bigger effect on lactate curve than Aerobic Cap Sprints during warm up increase sensitivity (responds quicker) Anaerobic Capacity When emphasizing a certain type of training, the other conditioning components need to go through maintenance training
Physiology of Training pH : 7.1 normal, at 6.9 glycolysis reduced, at 6.4 no glycolysis (H+ interferes w/ Calcium) Reason why pyruvate production has to be in tune w/ aerobic use of it: If you can Increase pyruvate production w/ Increase in aerobic then get more o energy w/ same drop in pH. Endurance training: decreases glycolytic enzyme Activity, Increases Krebs enzymes Enzymes- lower activation energy (amount of energy needed before o chemical reaction can take place.) Slow in speed at LT when doing strength training means strength work induced myofibrillar hypertrophy To maintain work, we rotate the effort among groups of motor units so that some contract while others rest. Lactate removed at slower rate below pH of 7.0 (decrease ATPase, PFK activity) High Acidosis training Gullstrand (1985)-daily high acidosis training caused mitochondria to lose o function and structure •

Lactate Values over 8mmol hinder oxidative processes in mitochondria and reduce effectiveness of aerobic training Max or near max intensity: Increase glycolytic enzymes (particularly o phosphorylase, pyruvate phosphokinase, hexokinase) and Increase Creatine Phosphate level and activity of creatinkinase and myokinase Too much acidosis training causes reduction in Adrenal hormones o o Same tissues exposed to acidosis repeatedly, extent of muscle damage may increase until muscular tissue is lost Acidosis disrupts muscle membranes and allow protein substances to leak into intracellular spaces Using High intensity reps for more than 3 weeks and LT decreases o With Increasing acidosis, PFK increasingly blocks the anae robic lactic o energy supply to stop further lactate production, preventing even lower pH Too much cortisol causes enzyme reduction Taking long rests (~5min) during interval training allows for ATP resynthesis thus Glycolysis will contribute more and mitochondria will be less active at the beginning. The power of an energy system is dependent on the concentration of the enzyme and the substrate. When ventilation is high, around 200 l/min, the respiratory muscles (notably the diaphragm) can experience fatigue. Limiting factors lie not in the area of energy supply (VO2max) but rather at muscle (bosch) level. Training goal: how to increase the power that the muscles are able to o generate. o

Purpose of training: Increase rate of energy release and delay fatigue Delay Acidosis by: 1. Reducing rate of Lactate Production 2. Removing Lactate from working muscle fiber 3. Buffering Lactate 4. Increase pain tolerance to lactate Increase Oxygen Delivery by: 1. Increase in pulmonary diffusion rate of Oxygen into bloodstream 2. Increase Red Blood Cell mass 3. Increase Blood Volume (decrease viscosity) 4. Increase Cardiac Output 5. Increase Muscle Capillaries 6. Improve Blood Shunting Increase Oxygen Utilization by: 1. Increase Mitochondria 2. Increase Aerobic Enzymes (low muscle pH reduces activity of aerobic enzymes)

3. Increase Myoglobin 4. Improve Glucose-Alanine cycle 5. Improve Malate-Aspartate shuttle Improving Rate of Lactate Removal Passive diffusion rate- depends on difference between concentration in o muscle and blood o Active transport- MCTs o Max removal rate at speeds 6-14% faster than LT at 8mmol (6-12mmol) pH drop makes lactate transporters less effective Endurance Training: Interval Training o Intervals of 50m or 10sec with 5-15sec pause will use oxygen reserve present in myoglobin. It recovers quickly, lactate is very low while the pace can be very quick (mile pace or better). During interval training (gerschler style), body tries to maintain blood pressure. (BP= Vcirc x TPR…TPR= total peripheral resistance) During interval, vasodilation occurs, lowering TPR. To maintain BP, Vcirc must rise. During rest, HR drops; to avoid rapid decline in Vcirc, Stroke Volume must increase. o Result is increase in volume and hypertrophy of left ventricle. !

Adaptation to training: Protein synthesis occurs only in presense of anabo lic hormones and each muscle fiber has various types of specific receptors, one for each different protein the muscle is able to synthesize o A particular biological signal will modify one of these receptors and allow it to combine with the anabolic hormone The anabolic hormone that enters the nucleus of muscle fiber, where it o finds the required data to synthesize new molecules in the archives of the DNA The training stimulus must “embarrass” the biological system which governs the targeted feature Adaptation Stages: o Adaptation Stage (2 wks)- Changes mainly motor control program nd th 2 -4 weeks- increases energy reserves and functional and structural protein o th th 4 -6 weeks- Central Optimization and subsequent reconstruction in o musculature 6th+- Coordination of transformation of all specific functional system to o reach the adaptation stage in specific performance •

Overload Principle- adaptation will not occur unless demands of training are greater than usual demands on physiological mechanisms If demand is too great, will breakdown o Increase in intensityo physiological adaptation occur more rapidly than with any method but plateau quicker because adaptations tend to be better neuromuscular responses and faster cardiorespiratory and metabolic responses that adjust faster Increase in volumeo physiological adaptations tend to continue at steady rate for longer time before plateau Decrease in rest- best for Aerobic and Anaerobic power o Asynchrony of recovery processes- different stresses require different o periods of time to recover. Reduction in training intensity results in faster loss of adaptation than de crease in volume Training duration and frequency more important than intensity for improving Aerobic Capacity in ST and FTA as long as minimum intensity is met With slow endurance work, FTa fibers have to time to replenish glycogen stores because ST do the work Running above LT may reduce Aerobic Cap in ST, even while it improves it in FTa Slope of lactate curve- flatter indicates better Aerobic and Anaerobic muscular endurance. Assumption that muscle lactate accumulating at slower rate, therefore pH will not decline as fast Each person has a stress tolerance Stressors=academic, social, emotional demands, illness, injury, training, o anxiety o Replacing stress stores=rest, sleep, good nutrition Most athletes respond well to training for 4-8 wks of season, then those who have been training too hard without recovery will show signs of overtraining It’s easier to maintain an achieved training level than to redevelop Blood flow determined by: Diameter of vessel through which blood moves o Pressure difference between heart and destination of blood o Blood shunting o o Blood viscosity A workout that defeats a runner fails in its purpose Shortness of breathe attributed to build up of CO2 in blood and respiratory centers of brain Decrease in resting HR due to o enlarged ventricular cavity Increase in filling and emptying of chamber o !

Gains from 15-20mi runs are usually not realize for 3 -4 weeks Heart’s initial response to sudden demand for Increase output is to Increase Stroke Volume, not rate Limit in trained runners lies Oxygen transport from lungs into muscles Amount of ATP produced by Aerobic system is directly proportional to activity of mitochondria enzymes Aerobic Fat power- lipid consumption rate- essential for marathon (at max 85-90% of LT) Speed of 92-100% marathon speed best for increasing lipid consumption o rate Slight Increase of body temperature of about 1 degree Celcius tends to improve performance Neuromuscular coordination improved by: o Synaptic modulation- each time a specific type of sensory signal passes through a sequence in synapse, the synapse becomes more capable of transmitting signal Synaptic Functions- can be modulate to increase or decrease number of o receptor sites for excitation or inhibition Lead to development of Motor Engrams= memorized skill in brain o Work that causes a rapid increase of the HR will improve stroke Volume Seem to need small amount of lactate to increase mitochondrial enzyme concentration Large amount of lactate stimulate lactic enzymes and inhibit aerobic o enzymes Is specific to fiber type. For example- below LT-stimulates increase in o ST more, while slightly above LT stimulates increase in the FTa more Muscle capacity to use lactate dependent on H-LDH enzyme Aerobic Threshold speed best for increase o o AT/LT alternating workouts work well too Athlete has to acquire a particular sensitivity and learn to distinguish race rhythm Progressive runs increase Oxygen uptake in FT because first part exhausts some ST, so FT step in as run progresses Running recovery will induce ST use lactate built up during effort Using High intensity reps for more than 3 wee ks and LT decreases Overuse injury occurs in the tissue that adapts the slowest “Must believe and adhere to the principle of never-ending progress” There are genetically determined high responders and low responders to different kinds of training.

Physiology/ Biochemistry Things the body tries to keep constant: pH, temperature, osmotic pressure, ion concentration, water content, and pO2 Increase in ADP and AMP activates PHOS to degrade glycogen and activate PFK which results in increase ATP production and lactate formation. Increase in ADP, Phosphate, and AMP work as feedback signals to stimulate oxidative phosphorylation AMP is converted to IMP and ammonia in adenylate kinase reaction. o When start too quickly in race, IMP is formed immediately. IMP gives direct negative feedback to muscle contraction. Malate-Aspartate shuttle system shuttles NADH into mitochondria When production of pyruvate and thus NADH increase above what can be handled by PDH and SS, excess pyruvate and NADH are converted to lactate and NAD by near equilibrium enzyme LDH. The more PDH, the quicker Aerobic system reacts Rate of glycogenolysis determined by glycogen phosphorylase Epinephrine- Increases glycogenolysis, inhbits glucose uptake Insulin- Increases glucose transport o Pre exercise carb intake- Increases insulin which has antilipolytic effect (decrease fat used) PDH regulates entry of Carbohydrate into Krebs cycle (Increase ratios of ATP and ADP, acetyl CoA, and NADH and NAD activate PDH). Lactate Liver converts lactate into glycogen to replenish its glycogen supply o Glucose converted to lactate by muscle, sent to liver. o Whether or not lactate is formed is related to the relative activity of the mitochondria, not on presence of oxygen •

Depends if mitochondria can utilize the NADH that’s being supplied. Lactate is used as fuel by heart and ST fibers. o o Lactate produced in FT fibers diffuse into surrounding ST fibers where it can be used. MCT1=uptake of lactate o o MCT4= lactate transport out of muscle cell, particularly when lactate levels are high Blood lactate inhibits conversion of glycerol into FFA. o During recovery protein synthesis Increases after long aerobic exe rcise, rate of noncontractile protein Breakdown Increases, myofibrillar breakdown unchanged Resistance exercise Increases protein synthesis and breakdown Glutamate combines with pyruvate to form alanine and z-oxoglutarate through alanine aminotransverse reaction Krebs Cycle o Concentration of Krebs intermediates regulate Krebs cycle This may be crucial to attain higher rates of mitochondrial respiration TCAI increase occurs when pyruvate formation by glycolysis exceeds its rate of oxidation by pyruvate dehydrogenase Speed of Krebs cycle depends on the concentration of oxaloacetate. st Power output during 1 seconds of exercise is limited by ability to utilize ATP rather than by rate of ATP regeneration Main control of glycolysis= Glyc. Phosphorylase and PFK=max activity max glycolytic power Degree of activity by mitochondria depends on the ATP/ADP ratio o Taking long rests (~5min) during interval training allows for ATP resynthesis thus Glycolysis will contribute more and mitochondria will be less active at the beginning. GP and PFK are reduced by acidosis thus enhanced product removal (increase intracellular H+ buffering and export of lactic acid) will au gment glyc. Power and capacity Large FT motor neurons have a higher threshold for activation and therefore require a high neural drive. H-LDH enzymes react with lactate molecules to form pyruvate LDH and PDH concentration help determine if Pyruvate goes to Lactate or AcetylCoA 2 kinds of LDH- one converts pyruvate to lactate and one converts o lactate to pyruvate As H+ increase, PFK decreases (inhibiting glycolysis) Presence of hydrogen ions alter spatial structure of enzymes. o !

At Aerobic Threshold start using FTa, at Lactate Threshold start using FTc; near VO2max start using FTb fibers. Muscle Damage causes Mechanical o Acute inflammatory response- when muscle fibers microtear, cells migrate to fiber and remove tissue debris, which causes swelling, which can damage muscle cell membrane Peaks around 24 hrs Hormonal o Cortisol levels increase (can be caused by mental stress in addition to common causes) Oxidative o Free radicals damage muscle protein, cell membranes, and enzymes If you do endurance training, of type 1 will increase. Mitochondria will also shift to outside of muscle cell as opposed to being in middle of muscle cell. Muscle Contraction occurs via: a nerve signal reaches the muscle and stimulates the release of calcium o (Ca2+). The sarcoplasmic reticulum, releases calcium, flooding the muscle ce lls o with it. o The calcium causes muscle contraction to happen, and when we want to relax the muscle the calcium is then pumped back into the SR, thus causing relaxation of the muscle. !

Anaerobic Lactic Endurance work- become specialized in recovering very quickly Training is something in order to improve, not something like a drug Running faster is better, but only if you can use the same effort, because it means that your shape is growing. But if you try to run faster because your % effort is higher, you go for more tough work, destroying yourself, never you must “search your shape with too hard workouts” Increase volume, speed, decrease recovery- Only if interval load is same-

CP system- Can either exhaust the stores all at the start or spare some for a later acceleration (Pendegrast) For 800m gradual deceleration, historical look shows fast first 200m, easing off for o the next 200m, then staying the same pace, slight pick up, or slight slow down for next 200m, then an inevitable slowing down for last 200. (Pendegrast) o A key element is the speed at the end of the first 200m, because this is the speed at the beginning of the lactic part of the race, if it’s too high your max lactic speed will fall too fast. So you should be settled down by 200m, not still driving. (Pendegrast) 800 runners with a 400m background can go out slightly faster because they have a better developed CP system. (Pendegrast) V-Va =where V is current running speed and Va is maximum aerobic speed. The difference is the amount of lactic produced, so the higher the Va then the faster the V, current speed, can be while producing the same amount of lactate. That’s why a powerful aerobic system is needed for 800m. (Pendegrast) 1,500m - theoretical-slightly faster first 200, then even pace, the first 200 is slightly faster so that the CP system is maximized with just enoug h left to supply a final burst(Pendegrast) 1500-historical- of 24 times studies, half had better first halves, and ha lf o had better second halves. 17 of 24 had halves within 1% of their finish time, and all 8 of the 1,500m times had halves within .5% of each other A complete 1,500m runner in tactical race that goes through 800m in o 90% of his 1,500m pace, should be able to close the last 700m at 95% of 800m speed. (Pendegrast) In slow tactical races, need a strong aerobic system to make sure most of the energy in the first half of the race is provided through predominately aerobic means. This spares the anaerobic system, so that when you really need to run fast, it can be put to use. (Pendegrast)
Running Economy Best improved by “overspeed” work. i.e. a race distance faster than your race. Also, economy best improved with little lactate, so long recoveries. 1500m runners are more economical at 5km speed, then 5km o runners. (Bakken) Differs on Cross-Country courses o Higher elasticity/reactive runners struggle on soft/muddy courses b/c they can not use high elasticity as much as on hard surface.

Danish children. (probably due to better running mechanics and lifetime accumulated volume of running)
Speed Maintenance for Distance Runners Real speed(30-150m) should be done every 10-14 days, a little more during racing season (Bakken) Sprint Training start You’ve got a 9v battery when getting into starting blocks, if you use 7v o on the start and getting into transition phase, then your fried. Need smooth acceleration.(Pfaff) Too much endurance training leads to conversion of transitional fibers to ST fibers, especially at an early age. (CF) How fast an athlete can move his feet (i.e. quickness) is an indication of the explosiveness of the athletes nervous system (CF) “Wait for it!” There is a lag time between when you increase the effort to accelerate and when you actually take off and move. (CF) Greatest Forces from hip joint Elastic power is the main determinant of acceleration and top speed. The momentary stretch of pre-flexed muscle at foot strike activates stretch receptors which recruit additional muscle fibers resulting in more force. (CF) Extensive Tempo Runs (60-80% velocity) improve recovery and increase capillarization, leading to an increase heating of the motor neurons in the muscle. This heating lowers the electrical resistance in the neural pathways within the muscle. (CF)] Speed Development Full or near full effort over short distances 30-60m (CF) o Special Endurance o Fast work of 150-300m. (CF) •

Overall muscle tone= proportion of contracted to non contracted muscle fiber. In a bundle of muscle fibers, the balance between what is contracted and what is not contracted o Generally, the lower the tone, the faster a muscle can contract and the stronger it is (CF) o If muscle tone is too low, you lose sharpness and the stretch reflex activity o Increase tone- through quick drills, sprints, dynamic exercises such a s vertical bounds, 100m hill sprints, or 200m reps a t comfortable pace in spikes (slight increase) (CF-MB) o Decrease tone- massage, long easy runs, LT runs, running in heavy shoes/flats, runs on really soft or hard surfaces, anaerobic work too close to race, cold water treatment (MB) Young sprinters need a longer General Prep. Phase (GPP)- 8-12 wks in order to develop a high aerobic power. Experienced sprinters need a short one b/c base is already there (CF)

(THOUGHT: May hold true for distance runners. Why rebuild a base every year to the same degree? Should be less time doing general stuff every year as carry over from last years training should take care of some of it.) o Tempo work AND speed work gradual increase in semi-wave like fashion then both drop slightly during main competition season.

CNS CNS energy pool- On a given day there is only so much CNS energy to expend. (CF) Optimal functioning requires (CF): o CNS has to be fully regenerated so that the chemical environment required for optimal transmission of nervous signals is intact. Motor pathways, characteristics of optimal technique and efficient o routing of motor signals can take place. CNS fatigue happens when by products of high intensity exercise build up to the point where the CNS impulses necessary to voluntarily contract muscle fiber are handicapped. (CF) Complete recovery from CNS work requires at least 4 8 hours before a similar CNS workout can be completed (CF) (THOUGHT: to see effect of CNS, compare the amount or # of reps of weight you can lift during your weight lifting workout after doing different kinds of workouts (easy, LT, anaerobic, sprint, etc)… The worse your weight workout is after, the more the running workout taxed the CNS) During exercise, the CNS fatigues first and causes the body to shut down before the peripheral musculature is totally exhausted. The differential between perceived exhaustion and actual exhaustion is designed to help the organism survive. (CF) If you keep ankle dorsiflexed, you do NOT have pretension in soleus. There is passive tension (like a simple stretch) not muscle activation. So not right idea. Need neutral position (90 degree in ankle). (Bosch) Key to sprinting isn’t always muscle force contraction but rather how quickly you can get ready to contract again….i.e. repolarize
Strength Training Loads that permit only a low number of reps (2-6) challenge the CNS and are accompanied by gains in the CNS with little or no change in cross-section Any CNS training done with less than the highest quality can reinforce o neuromuscular patterns which are counter productive Conversion of Strength to Power Done via sprinting or plyos o •

Strength depends on Muscle fiber type o Cross-section of muscle o o Number of muscle fibers participating in contraction Good flow of blood in muscle o On the degree of muscular expansion (stretch) o o On the regulation of the muscle tone Strength training that increases the diameter of muscle fibers must be accompanied by training that increases mitochondria and capillaries or else density of both is much less. Autonomous protective backup- the superhuman strength during life threatening situations. Strength and coordination are interrelated; don’t isolate muscles all the time. Isolated training is only applicable to concentrically working o monoarticular muscles that can be coordinated easily. Power training Improves performance in 3 stages: o Improvement in intermuscular coordination (groups of muscles work better) Improvement in intramuscular coordination (individual muscle works better) Hypertrophy (after about 12 weeks) Power methods- maximum speed with both low and high loads o Rate of Force Development o With Ballistic training, increased RFD and increased rate of onset of neural activation •

The greater the complexity of coordinating a group of muscles during running, the greater the variety needed in exercise program. Hypertrophy Most important requirement for hypertrophy is breakdown of muscle o protein. Highest breakdown occurs with medium reps (6-12) Protein breakdown dependent on speed of breakdown and mechanical work. Increase muscle cross section=s high volume, medium intensity work (3o 5 sets of 5-15 reps at 65-75% max) Maximum Strength Intramuscular coordination improvements: o 1. more motor units recruited For running there’s a stereotypical pattern of recruitment within the muscle involved. Any small alteration can • •

change the pattern, shifting a muscle from a low stimulus threshold to a high stimulus threshold. This is why strength training must be specific o 2. Increase the frequency of the stimulus Increase the length of time for which a maximum stimulus frequency can be maintained. 3. Improve the synchronization of motor unit activity. Intermuscular coordination improvements: o 1. Decrease in co-contractions (tightening of both agonist and antagonist). 2. Improve coordination between the various agonists. Reactive muscle action Reactive muscles work more or less in isometry. o o Has an optimal length for reactivity The cycle for prestretch and discharge is short, if the muscle has first o been tightened Training types: o 1. Training for max power in isometry with an optimum working range. Heavy weights moved very slowly. 2. Training reactivity by means of the strength of impact. Movements made rapidly, with prestretch using lightweight barbells. Most important muscle groups that work reactively during running: Erector spinae group o When standing on 2 legs, dorsal muscles are limiting factor. Standing on one leg makes the leg muscles the limiting factor. Hamstrings Triceps surae group (soleus and gastrocnemius) Rectus femoris and small, lower leg muscles Abdominal muscles Explosive concentric muscle action The contractions are concentric over a range that is determined by o movement. Muscles for generating power o Gluteus maximus Iliopsoas Vastus segments of the quadriceps o The correct muscles must be the limiting factor during p ower training. George Gandy: •

General Advice: Elite athletes are genetic freaks so sometimes all the studies by physiologists do NOT apply to them because the studies are done on the norm. (Kraaijenhof) All the energy systems are interrelated; they are all wo rking, so you can’t individually train anaerobic power or ATP-CP system or whatever. (Pfaff) •
•
•
•
You have to take out the lumping in a muscle or the athlete can lose tremendous power b/c that lumping causes that part of the muscle to be ineffective Every individual component in a training program is separate and has its own cycle. o Supercompensation has to take place within each component.
ALTITUDE: Most of the benefit of altitude is living there. Takes an hour and a half before EPO levels start to rise If you do altitude correctly, they have an 8% increase in RBC count, gives 2% increase in performance. Important not to lose biomechanical efficiency. Use pulse oximeter to see if get hypoxic response. Nothing accomplished living below 6200 feet or so. • • •

Peaking Time of tapering off depends on fiber type and event of athlete. More FT fibers, longer taper. FT fibers need longer tapering. (Kraaijenhof) Tapering aerobic training over a matter of weeks creates a stimulus that actually decreases that ability(simmons) . Decrease in volume sends singal to body that you no longer need the same blood (simmons) volume and Oxygen carrying capacity. During peak, avoid fatigue during week preceding race, while sustaining physical fitness. (2-factor model theory). •

My general thoughts: Drawback to traditional aerobic base was the sprinter was detraining all the speed capabilities that had been built up the prior year •
(THOUGHT: may be what happens when distance runners go back to entirely aerobic base. Lose anaerobic capacity/power that was built up and lose speed. Instead try and maintain these during base so that they can be increased later) o You give away so many of the things you built up and spend so much time having to relearn it. (THOUGHT: to see effect of CNS, compare the amount or # of reps of weight you can lift during your weight lifting workout after doing different kinds of workouts (easy, LT, anaerobic, sprint, etc)… The worse your weight workout is after, the more the running workout taxed the CNS) Constantly challenge the organism (THOUGHT: Don’t give/post a monthly/weekly schedule. Have a general or even somewhat specific training outline for coaches use, and briefly show the athlete to show that you have a plan, but don’t give it to him. Make athlete meet everyday to find out what they are going to do. This way you can make day to day adjustments based on how the athlete is recovering/training/etc. and he doesn’t feel bad for pushing back a workout or skipping a workout.) (THOUGHT:Make practice/workouts always a positive experience.) o o

Overtraining: “As soon as the normally keen athlete shows signs of reluctance or slackness, it should be taken as a sign of incipient overtraining or an incorrect balance in the (East German) training schedule.” Running too close to max too often results in excessively high stimulation (east german) producing maximum excitation in the CNS and can lead to its inhibition. •

Philosophy/Theory of Training •
•
“There is no right of wrong system of training runners, just a continuum ranging from successful to unsuccessful.” (Simmons) Athlete Centered training- Individual athlete at center. o Coach centered training- athletes are simply inputs into training system. o o Must specifically prepare for the exact demands of how the race is hoped to be run and not just the physiological aspects. East German Textbook (East-German) Knowledge= Theoretical Knowledge + Practical Experience o
General versatitlity gives the background for later specialization in one event. “The broader the base is, the higher will be the standard in one special event.” o Skills become stable only if often repeated at short intervals Periodization o Proceed from simple to complicated. From general to specific. Science strives to generalize, in sport one is concerned with the athlete, as an (Bosch) individual. Running style (reactive vs. flat) will help determine training. o

Injuries Hamstring o Most hamstring injuries is a loss of coordination (contracts at wrong time or with an incorrect amount of force.) •
