WorksheetsMuscular adaptions to endurance
Total questions: 10
Worksheet time: 7mins
Which has a higher capillary density?
Type I
Type IIx
What are some of the long-term positive muscular adaptations to endurance activity?
Repeated bouts of PA without suitable rest periods can cause overuse injuries.
slow twitch(type 1) Hypertrophy
Slow twitch fibres develop bigger and more efficient capillary beds, increasing mitochondrial density.
Increased availability of fuel source required (CP, Glycogen, Triglycerides)
Abduction
Within the slow twitch muscle fibres what are the training adaptation/s?
Increase in anaerobic enzymes
Increase mitochondria density
Increased creatine levels
Faster lactate removal
All of the above
Myoglobin is responsible for:
Transferring oxygen from capillaries into the muscle cell
Respiration and the aerobic production of energy / ATP
Breaking down glycogen
Transferring CO2 back into alveoli from the blood
A trained athlete will have a/an ______level of haemaglobin per ml of blood
increase
decrease
little to no change
Within the slow twitch muscle fibres what are the training adaptation/s?
Increase in anaerobic enzymes
Increase mitochondria density
Increased creatine levels
Faster lactate removal
All of the above
• Endurance training (a) the number of capillaries per muscle fiber. More blood flow to muscles bring oxygen & nutrients
Inreased lactate (a) . Working muscles can tolerate greater levels of lactate and lactate production is delayed. Therefore, allowing athletes to endure higher intensities for longer
Improved body (a) , increased fat free body mass. Better body to weight ratio, positively affecting speed and power
Endurance training Increases basal metabolic (a) . This has a positive effect on body weight and allows for a more efficient use of energy
