When Is Sport Unhealthy?


Too frequent workouts can be just as dangerous as a sedentary lifestyle. Studies at the University of Lausanne revealed that people who exercise more than fourteen hours per week can hardly boast of good health, as written in The Telegraph.


Scientists interviewed more than 1,200 people aged 16 to 20. They were asked about their training regimen from February 2009 to January 2010.

When a young person actively trained, anxiety and stress lowered, and brain activity and self-esteem increased. The pluses of physical activity were noted by 5% who really trained a lot. The negative effect was caused by inflammation from excessive load.

Mental and physical health was assessed using the WHO system (graded on a scale from 0 to 25; when the index was below thirteen, the condition was considered poor). The average figure was seventeen. All the respondents were divided into groups based on how often they practiced during the week. Almost 35% trained little (less than 3.5 hours per week). 41.5% had average indicators of training frequency (from 3.6 to 10.5 hours), 18.5 % – quite high (10.6 to 17.5 hours), and 5% – very high (over 17.5 hours).

It turned out that people from the first and the last group were more frequently assessed below 13 on the WHO scale. The people who trained more, generally felt better. Those who trained fourteen hours a week felt best of all. However, everything changed when a person trained more than 17.5 hours.
