EFFECTS OF EXERCISE ON MENTAL HEALTH OUTCOMES IN ADOLESCENTS.

According to Eather, Morgan, and Lubans, 20% of adolescents worldwide suffer from some form of mental illness. Their research aims to show that exercise does improve the mental health of teenagers. Their research, however, failed to show that Cross-fit type training done by adolescence is successful in reducing the risk of developing mental disorders. This, however is not all the research proved. Self esteem was shown to rise in students who participated in the research, showing that although there is no proof that intense exercise among teens can reduce the possibility of developing mental health issues, it can improve their self esteem, which also has a hand in their mental stability.
