Correct option is D
The correct answer is (d)
A. Maximum load to exhaustion, inducing strength gains: This approach involves lifting maximal or near-maximal loads until exhaustion, aiming to stimulate adaptations in muscle strength. Performing exercises with heavy loads recruits a high threshold motor units and activates a greater number of muscle fibers, leading to neuromuscular adaptations that enhance strength. Over time, consistent exposure to maximal loads promotes increases in muscle fiber size (hypertrophy) and neural adaptations, resulting in improved strength capabilities.
B. Submaximal loads to exhaustion, inducing hypertrophy: Contrary to the focus on maximal loads, this approach involves using submaximal loads (typically between 60-85% of one’s one-repetition maximum) to induce muscle fatigue and stimulate hypertrophic adaptations. By performing multiple repetitions to near exhaustion with submaximal loads, individuals promote metabolic stress, cellular swelling, and mechanical tension within muscle fibers, all of which contribute to muscle growth (hypertrophy). While this method may not directly target maximal strength gains, it is effective for promoting muscle size and increasing overall strength potential.
