Overtraining - Conclusion
Over the past month I’ve outlined what exercise scientists consider as “overtraining”. If you’ve been following these posts you have probably come to the conclusion that overtraining does not exist. I would have to agree with that due to the lack of clear evidence of support on the topic. Although I could not put it so elegantly as CT Fletcher, I must admit that the human body does possess a high capacity to adapt to any stimulus that it is given. An adaptation to training can occur even after one bout of resistance exercise (known as the repeated bout effect). Most of you spend the majority of your day sitting at sedentary jobs or in classrooms. To have a truly taxing workout for 1-2 hours per day seems implausible to hinder recovery and performance. The problem is that there are too many variables (nutrition, sleep, mood, etc) to consider to even have a well-controlled study on overtraining. Of course, you must have proper rest and adequate nutrients to continue performing at a certain level. Lacking those two variables alone could be the culprit in the decrements you see with training and not the actual training itself. The best available source for coaches to try to diagnose overtraining is in this checklist provided by the ACSM review. I hope that you were able to take away the recent standpoint on overtraining in the scientific community and understand the lack of concise and consistent data in support of it.
