Homework Answers
Endurance training trains aerobic system rather than anaerobic system. A well trained athlete can only do endurance training.Endurance training include activities like marathon running . That is it includes sustained smaller movements.
In endurance training the factors increase include in the options given is
Only the Muscle mitochondria number
Muscle fibres are two types slow switch muscle fibres and fast switch muscle fibres. Slow switch muscle fibres are used for used for long run smaller movements and they are fatigue free. Slow switch muscle fibres are type I and they are used in endurance training. The fast switch muscle type bis Type II . It's not used in endurance training.
Lactate production is decreased in edurance training. Because endurance training induces adaptation that decrease lactate production.
Endurance training induced reduction in both muscle and liver glycogenolysis. Hence the glycogen level is not depleted.

3. Muscles respond to strength training with hypertrophy. Hypertrophy occurs by a) increasing the number of muscle fibers in the skeletal muscle. b) increasing the diameter of each fiber by adding more myofibrils. c) adding more mitochondria and myoglobin to each fiber. 4. Endurance training (such as training to run a 10k race) aims to increase the % of ATP generated from aerobic respiration during times of intense exercise. Which fiber type is primarily recruited for this type of endurance...

The excitation, contraction, and relaxation of skeletal muscle
require the use of ATP. Because only limited stores of ATP are
immediately available in muscle tissue, ATP must be continually
supplied if contractile activity is to continue.
Depending on the type of movement or exercise, one or more
pathways can be used to provide the most efficient way of supplying
the ATP.
