Outline of Final Research Achievements

The aim of this study was to investigate developmental growth and seasonal variations of multifunctional motor abilities of elementary school children in Hokkaido. 1st to 6th grades elementary school children participated. Agility test, N Challenge, and a repetitive rebound jump performance test using ballistic stretch-shortening muscle contraction were used for evaluating motor abilities. Physical growth was measured by height and body weight. At snow-fall winter season, agility performances in elementary school children in Hokkaido were lowered than those at non-snowfall seasons. Moreover, ground contact time during a repetitive rebound jump test was extended at the snowfall winter season, suggesting that ballistic muscle contraction ability of children was lowered during the season. Taken together, our results suggest that multifunctional motor abilities of elementary school children in Hokkaido would be lowered at snowfall winter seasons, despite children showed physical growth.
