[High volume exercise can be unhealthy]

Abstract

There are positive health effects of exercise performed at regular intervals also in high volume exercisers. However, at present there is no exact definition of the optimal dose or the maximal safe dose of exercise, nor can the level of exercise to induce increased risk of harmful effects be defined. People who often exercise with a high volume and intensity should therefore individually consider the health-related effects and possible risks of their training as well as the physical or psychological warning signals.
