Development of physical fitness in 66 primary school children (boys: n = 42, girls: n = 24) according to class and sports club participation (Yes: n = 49, No: n = 17): (a) 50-m sprint, (b) 1-kg ball push, (c) triple hop, (d) stand-and-reach, (e) star coordination run, and (f) 9-min run. Notes. *(p < 0.05), †(p < 0.01), and ‡(p < 0.001) indicate that performance was significantly better in children with than without continuous sports club participation; filled circles indicate children with and unfilled circles indicate children without continuous sports club participation; for the 50-m sprint and the star coordination run, lower scores indicate better performance; for the 1-kg ball push, the triple hop, the stand-and-reach, and the 9-min run, higher scores indicate better performance.
