“Do you train your muscles better if you first ensure that you are experiencing fatigue and then go all out? We do this at my Bootcamp class: first, we have to feel fatigue in a squat and then we sprint at full effort. I find this very heavy. Is it really better?
Mark Chen, Physiotherapist
‘Better’ is a difficult word, because that depends entirely on the goal you want to achieve. Still, I can be quite clear about creating fatigue in preparation for an explosive effort. Don’t, unless there is a very good reason for it.
Fatigue in a muscle involves a number of physiological changes in the circulatory system around the muscles. Simply put, it negatively affects the control of the muscle and therefore it will function less efficiently. You’ve probably felt that already!
Muscles with fatigue also lose their ability to contract and relax properly. If you demand an explosive action in that state, the performance you can deliver will always be below your actual capacity. I can even go one step further and say that at such moments, strains and tears occur most often. Take a look at football matches and the number of cramps and injuries that occur in the later stages of the match. It’s a very obvious percentage.
Creating fatigue in the muscle system can certainly have positive aspects, but should usually be kept until the end of a Bootcamp class. Ask yourself if your trainer has a good reasoning for this way of training. It is difficult for me to estimate how far your athletic ability reaches! If he can not explain it in a way that is sensible, I would be very careful with this combination. Listen to your own body and play the long game, don’t risk an injury.
