What term describes the reduction of training adaptations after stopping anaerobic training?

• A. Overtraining
• B. Overtraining syndrome
• C. Detraining
• D. Maintenance

Answer: (C)

Detraining is the reduction of training adaptations that occurs when the stimulus from anaerobic training is removed. When you stop sprinting, lifting heavy, or performing other high-intensity work, the body no longer needs the same level of neural efficiency, high-energy phosphate stores, glycolytic enzyme activity, and muscle fiber adaptations that were developed with training. As a result, strength, power, sprint speed, and related metabolic capacities tend to decline, returning toward pretraining levels. The rate and extent of loss depend on how long you stop, how trained you were, age, and nutrition. Early changes often involve neural and performance aspects, while metabolic and structural adaptations (like enzyme activity and muscle fiber characteristics) fade more gradually. Some skills and neuromuscular patterns may persist for a while, but the overall anaerobic capacity typically decreases without ongoing high-intensity stimulus. This is different from overtraining, which stems from excessive training load relative to recovery while continuing training, and from maintenance, which aims to preserve gains with reduced training rather than allow them to fade.
