Worked Solution & Example Answer:The physiological adaptation that is likely to occur from progressively overloading a strength-training program is an increase in (A) muscle hypertrophy - HSC - SSCE Personal Development and Physical Education - Question 5 - 2015 - Paper 1
Step 1
muscle hypertrophy
Answer
Muscle hypertrophy is the increase in muscle size due to the enlargement of its cells, which is a fundamental adaptation to strength training. Progressive overload, which refers to gradually increasing the amount of work or resistance, stimulates muscle fibers, leading to micro-tears that, upon repair, result in larger muscle fibers.
Step 2
Step 3
muscle contraction speed
Answer
Although strength training may lead to some improvement in muscle contraction speed, it is not the most significant adaptation. The speeds of contraction are more associated with the type of muscle fibers being recruited, rather than the overload principle specifically.
Step 4
the number of fast twitch muscle fibres
Answer
The number of fast-twitch muscle fibers can increase with specific training, but this generally happens more with specialized training techniques. Strength training primarily focuses on the hypertrophy of existing muscle fibers rather than increasing their number.
