Peak anaerobic power in master athletes

Area of Science:

• Exercise Physiology
• Aging Research
• Sports Science

Background:

• Age-related decline in maximal physical performance is a concern for healthy individuals.
• This decline may stem from intrinsic aging processes or reduced physical activity.

Purpose of the Study:

• To determine the age-related deterioration of maximal instantaneous muscle power (peak power, Wpeak) in master athletes.
• To assess the contribution of quantitative (muscle mass) and qualitative factors to this deterioration.
• To compare power-trained and endurance-trained master athletes with young athletes and untrained subjects.

Main Methods:

• Studied two groups of master athletes (power-trained P, endurance-trained E) aged 40-78 years.
• Included young athletes (17-26 years) and untrained subjects (U, 22-67 years) for comparison.
• Assessed lower limb muscle plus bone volume (LMV) via anthropometry and peak power (Wpeak) using a vertical jump on a force platform.

Main Results:

• Lower limb muscle plus bone volume (LMV) remained stable from age 20-45 years in all groups, then progressively reduced in older age.
• LMV values were consistently higher in power-trained (P) athletes compared to endurance-trained (E) and untrained (U) individuals.
• Peak power (Wpeak) data, while not fully detailed in the abstract, is implied to show age-related decline influenced by LMV changes.

Conclusions:

• Muscle mass and peak power decline with age in master athletes, influenced by both aging and training status.
• Power training appears to better preserve lower limb muscle volume compared to endurance training in older athletes.
• Both quantitative (muscle mass) and qualitative factors likely contribute to age-related performance decrements.
