Overexertion injuries in keep-fit athletes. A study on overexertion injuries among non-competitive keep-fit athletes

During three years, 274 exertion injuries in middle-aged keep-fit athletes were collected. A keep-fit athlete was a person, who regularly took part in noncompetitive sports activities. Exertion injury was a nontraumatic pain syndrome in the musculo-skeletal system. In the material, there were 35 women and 239 men. Most of them were 30--39 years old. Most exertion injuries took place in July, August, and September. About 80% of the patients were joggers. 80% of them had been training regularly for more than one year. At the moment of occurence of the symptoms, 68% of the patients trained 3--5 times a week. Joggers ran approx. 40 km/week. About 30% of the injuries took place in the knee, 24% in the ankle, heel and foot, 17% in the leg, and 9% in the achilles tendon. Almost one fifth of the pain syndromes were chronic in nature. The majority responded well to rest and to conservative treatment. Fifteen cases were treated surgically. Most of the exertion injuries were typical exertion syndromes seen also in competitive athletes. Others were degenerative changes, organic anomalies etc., which revealed their first symptoms during regular keep-fit activities.
