Physical fitness of elementary school children has reportedly decreased over the past few years, physical fitness of present-day children who exercise regularly may not necessarily be inferior to that of the children in the past. This study aimed to examine the secular trend and sex differences in physique, muscular strength, and flexibility in 9–10-year-old children who took part in swimming practice and training at a swimming sport club. The participants were divided into the past group (1996–1998) comprising 601 persons (boy: n = 251, girl: n = 350) and the modern group (2010–2012) comprising 456 persons (boy: n = 201, girl: n = 255). In conclusion, the physique of elementary school children regularly attending the swimming sport club did not show marked time period and sex differences. Muscular strength was superior in the present-day children and ankle mobility was superior in the past children. In addition, marked sex differences in muscle strength and flexibility, except for trunk flexion, were not found in both periods.
