Effects of a regular motor activity on somatic and fitness variables in boys aged 17 - 18 years
Study aim: To assess the somatic and fitness changes in semisedentary boys persuaded to undertake Nordic Walking activities throughout a school year.Material and methods: Two groups of schoolboys aged 17 - 18 years were studied: regularly attending physical education (PE) classes (Group A; n = 46) and those who avoided PE classes by submitting sick note ors excuses signed by parents (Group N; n = 29). The latter ones undertook Nordic Walking training (3 sessions a week throughout the school year). Group A undertook no motor activities except regular PE classes. At the beginning (Pre) and at the end of the study (Post) all boys were subjected to 7 fitness tests: 50-m run (50 m), shuttle run 4×10 m (SR4), 1000-m run (LDR), sit-ups (SUP), standing broad jump (SBJ), pull-ups (PUP) and stand-and-reach (STR).Results: Mean Post-Pre changes in Group N evidenced significant improvements, compared with Group A, in most studied variables - body mass, body fat content, 50-m dash velocity, PUP, SUP, STR, SR4 velocity, no significant, unfavourable changes being noted.Conclusions: Nordic Walking, being an attractive form of activity, may be an easy way to encourage people to undertake motor activities thus improving the health status.
