The purposes of the present study was to investigate the age-related development of fundamental running and footwork abilities from a viewpoint of jumping ability characteristics used by Endo et al. (2007). A total of 389 boys (12 yr: 85, 13 yr: 72, 14 yr: 60, 15 yr: 53, 16 yr: 57 and 17 & 18 yr: 62) conducted counter movement jump (CMJ) and five-repeated rebound jump (5RJ). CMJ and 5RJ abilities were evaluated by jump height and RJ-index (=jump height/contact time), respectively. Fundamental running and footwork abilities were assessed 50 m run, 20 m shuttle run and lateral side-step. Division of jumping ability types were as follows: CMJ ability corresponded to RJ ability (Even type), RJ ability was superior to CMJ ability (RJ type) and CMJ ability was superior to RJ ability (CMJ type). 50 m run, 20 m shuttle run and lateral side-step in RJ type were significantly higher performances than those in CMJ type and Even type. This result revealed that fundamental running and footwork abilities in RJ type developed at a high level compared with CMJ type and Even type after the onset of growth spurt and suggest that the assessment of jumping ability using CMJ and RJ is useful to evaluate the physical fitness and motor ability for children.
