In 1988, maximum oxygen uptake (VO2max) was 68 +/- 5 ml/kg.min in the 18 still active runners, 55 +/- 8 ml/kg.min in the 9 inactive former runners, 45 +/- 6 ml/kg.min in bobsledders, and 44 +/- 6 ml/kg.min in controls. In 1988, the 27 runners had modest but significantly more frequent radiological signs of degenerative hip disease than non-runners, while no influence of long-term physical training on the radiological state of the ankle joint was found. In 1988, runners tended to report themselves healthier; subgroup analyses revealed 1) that this superior self-rated health was confined to those runners still active in 1988 (p less than 0.05) and that VO2max in 1988 was associated with subjective wellbeing (p less than 0.05), and 2) that body fat content was the strongest negative predictor of self-rated health (p = 0.001). 22% of former elite athletes indicated chronic, sports-related complaints but nevertheless rated their health as good as their athletic counterparts free of complaints. 53% of the elite athletes felt that the \"benefits\" of their own sports career outweighed its \"costs\", and in two of five of all athletes even \"by far\".

Thus, in terms of O2 consumption wmax is about four times larger than the subjects VO2max. The peak instantaneous power during a vertical jump off both feet (w) in non athletic subjects is about 50-55 W kg-1 and attains 70-75 W*kg-1 in \"power\" athletes. Both wmax and w decrease when the all-out efforts is performed from a priming aerobic exercise: if the intensity of this last approaches VO2max, then wmax and w are reduced to about 75% the value attained from rest. Thus, in the course of high intensity efforts, an athlete can develop a still remarkable fraction of his maximal absolute power. The decrease mentioned above is proportional, and presumably causally related, to the decrease of the high energy phosphate concentration occurring in the muscle at the onset of the exercise, and maintained throughout the effort duration.</p>","PeriodicalId":76534,"journal":{"name":"Schweizerische Zeitschrift fur Sportmedizin","volume":"39 3","pages":"103-11"},"PeriodicalIF":0.0,"publicationDate":"1991-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13084855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Craniocerebral trauma accounted for about 65% of the residual lesions and for 69% of the lethal injuries related to bicycle accidents. A relatively simple and effective protection for these injuries would consist of the use of a helmet. To estimate the expected reduction of head injuries if everybody had a helmet, the regression analysis of a previous study from Seattle was applied. By wearing hard-shell helmets, there would be a reduction in number and severity of 7500 head injuries and a decrease of 2000 hospital admissions each year in Switzerland.
