Friidrottsungdomars fysiska kapacitet över tid
En retrospektiv studie av intagningstesterna vid friidrottsgymnasiet i Växjö mellan åren 1982 ? 2009
Background: Today when leisure time is spent, spontaneous sports activities decrease, due to a more comfortable way of living and physical capacity among non active adolescents decreases. There for it´s interesting to see how the physical capacity level has changed over time among young people participating in organized leisure time sports.Studies around the world show that young people standing outside organized sport activities have tended to decrease their physical activity levels over the last few decades. Less leisure time is spent doing physical activity and sometimes gets put into context with increased time spent behind the computer or inactivity.Design: A retrospective study of the test results on physical capacity between 1982 and 2009 for students applying to Växjö track and field high school. A total of 635 students (15 years old) have done 11 physical tests during the years. Five of these tests, with enough participants (at least 100) and documentation over at least 10 years, were used in this study.Results: This study shows that young track and field athletes have maintained the same physical capacity from 1982 to 2009. Among boys strength endurance has increased slightly (P<0.03), while the maximum strength (P<0.01) and speed (P<0.02) marginally declined. Among girls no trends can be seen in either direction. Conclusions: Due to decreased physical capacity among teens standing outside organized sport activities, it is interesting to see that well trained teens maintained their physical capacity over the same period of time, the last 30 years.
