This article summarizes the relevant literature regarding post-workout nutrient timing and its importance to training adaptations, specifically increasing skeletal muscle hypertrophy and replenishing skeletal muscle glycogen stores.
Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.
Understanding how the body adapts to the overload of aerobic exercise is critical to designing effective exercise training programs, monitoring exercise responses and progress, and assessing training outcomes.

Older adults who desire to remain physically active at work, recreation, or sport can improve muscular strength, physical performance, and injury prevention if engaged in a properly designed resistance exercise program. The programming considerations presented herein may serve as a useful reference for strength and conditioning professionals working closely with active older adults.

Neural adaptations help mediate growth-related processes and the early increase in strength is attributable mainly to improved neural function. Along with neural changes, various aspects of the protein metabolism in the muscle are changing in the early phases of training.
