Excessive exercise is equally detrimental to the mental health and self-esteem with a sedentary lifestyle, according to a new study.
 
Scientists from Switzerland and Canada have found that teenagers and young adults who exercise too have increased odds of low self-esteem, anxiety and stress compared to those who exercise very little or not at all.
 
Their findings are based on research with 1,245 teenagers and young adults aged 16-20 years from the Switzerland.
 
Those of them exercised more than 17.5 hours per week had the same level of well-being with those who exercised less than 3.5 hours a week.
 
Experts recommend for good mental and physical health and fitness 7 hours a week.
 
As the researchers write in the "British Medical Journal» (BMJ), the study volunteers completed detailed questionnaires about their height, weight, socio-economic status, sports, injuries during sports and wellness.The well-being was assessed with the so-called Index of Wellbeing of the World Health Organization (WHO), who scores from 0 to 25. Values ​​below 13 indicate poor welfare.
 
Researchers have classified adolescents and young adults in four categories, depending on whether exercised. The categories were low physical activity (0-3,5 hours per week), moderate (3.6 to 10.5 hours a week), high (10.6 to 17.5 hours per week) and very high (over 17.5 hours per week).35% of volunteers had low physical activity, 41.5% moderate, 18.5% high and 5% too high.
 
As shown by the analysis of the data, the better wellbeing were teenagers and young people with high physical activity, especially those who exercised 14 hours a week.Compared with these young people, who were in the low physical activity group and those who belonged to the group with very high physical activity were twice as likely to have a score on the Index of Wellbeing below 13.This finding led the researchers to conclude that the exercise "cease to exercise a beneficial effect (in the mood) and converted into an independent risk factor for poor welfare when more than twice the recommended hours of physical activity per week."
