Detraining

Detraining refers to the loss of fitness and performance gains when regular training stops or significantly reduces. It leads to decreased cardiovascular efficiency, muscle strength, and endurance. For example, VO2 Max can decline within two weeks of inactivity. Runners may experience increased fatigue and slower race times. Detraining matters because it highlights the importance of consistent training to maintain fitness levels. To mitigate its effects, runners should incorporate light activity or cross-training during breaks. Understanding detraining helps athletes plan recovery periods without losing significant progress.
