Chronic Adaptions Anaerobic

Chronic Adaptions to Anaerobic Training Muscular Fast Twitch Fibres Muscular hypertrophy Increased muscular stores of ATP and PC Increased glycolytic capacity Incrased ATPase Cardiac hypertrophy Increased tolerance to metabolic by products an increase in the strength and size of connective tissues such as tendons and ligaments

Increased glycolytic capacity Increased muscular stores of glycogen Increased glycolytic enzymes occur during adaption to anaerobic training. What energy system would this benefit? ? How would this benefit performance? Increased Glycogen stores = Increased amount of glycogen as a fuel source Increased glycolytic enzymes = Increased Rate of ATP release from glycogen .

Muscular Hypertrophy Anaerobic training can lead to significant enlargement of muscle fibres. (Hypertrophy) This includes increase in the number and size of myofibrils Increased size of actin and myosin Increased total amount of contractile protein. Increased amounts of connective tissue The greatest gain we get is in Type 2 A Fast Twitch Fibres Muscular Hypertrophy = Greater strength What other fitness components would benefit form muscular hypertrophy? ?

Increase in the strength and size of connective tissues Includes tendons and ligaments This is associated with the increase in size of the muscle and allows a stronger attachment to the bone. How would this benefit performance?

Increased tolerance to metabolic by products Anaerobic training allows for the athlete to produce very high levels of lactic acid The athlete develops a greater tolerance to lactic acid. (Lactate and H+ ions) This means that an athlete can use a higher percentage of the anaerobic systems creating a faster rate of ATP production. This increases the bodies ability to work at higher intensities.

Increased muscular stores of ATP and CP Anaerobic training results in greater stores of ATP and PC as well as the enzymes we need to break them down. What energy system would benefit from this? How would it improve performance?

Increased ATPase is a catalyst that assists in the breakdown of ATP into ADP. The increase of ATPase helps increase the rate of turnover of ATP.

Chronic Adaptions to Anaerobic Training Neural Adaptations from Strength Training Increased muscle buffering and increased motor unit recruitment Increased speed of nerve-impulse transmission to the muscle cells Increased number of motor units recruited Increased speed of muscular contraction.

Increase in the speed of nerve-impulse transmission to the muscle cells an increase in the speed of muscular contraction and therefore greater rate of force development How would this benefit in sport?

Increase in the number of motor units recruited Results in a more efficient relationship between nervous and muscular system therefore greater force production when muscles contract

Cardiac hypertrophy Hypertrophy (enlargement) of the heart. Anaerobic training produces an increase in the thickness of the ventricular walls

Your turn! Name the training methods that develop chronic anaerobic adaptations in muscle tissue. A) Identify three types of athlete most likely to develop chronic adaptations as a result of participating in an anaerobic training program. B) For each athlete identified in part (a), explain why they develop such adaptations. .

Still your turn! Outline three chronic adaptations that may occur at the muscular level as a result of involvement in an anaerobic training program of at least 6 weeks' duration. Discuss how these adaptations can lead to improved performance. .

One more! An athlete participates in the following training program over a period of 6 weeks. Session 1: 5 × 100 m runs, each taking 14 seconds 5 × 80 m runs, each taking 12 seconds Work-to-rest ratio of 1: 3 Session 2: 5 × 60 m runs, each taking 9 seconds 5 × 40 m runs, each taking 7 seconds Work-to-rest ratio of 1: 5 . The athlete notices a reduction in time taken to complete each of the runs as the weeks progress. Identify and explain the chronic adaptations that have occurred to allow the athlete to run faster.
