研究成果概要
Introduction
It has the very important role to develop the player who has excellence in soccer, talent identification and development process. In the possible predictor of talent identification, physiological and anthropometric factors were thought to be as usual index (William and Reilly, 2000). However, there are few researches in the case of female elite soccer players. Thus in this study, we aimed to investigate the possible predictor of talent identification index from the motor ability and anthropometric characteristics. To reveal this issue, we clarified characteristics of motor ability and anthropometrics of female elite soccer players.

Measurement
Participants were 97 female national team soccer players (Japanese female national team player and there sub-team , National team aged under nineteen year-old, National team aged under sixteen year-old). Players were divided into “elite” or “sub-elite” players by coaches' subjective assessment. Elite players have took part in the FIFA World Cup or Olympic game. Then their speed (40m sprint test), agility (10m×5 agility test), power (5 step bounding power test) endurance (Yo-Yo intermittent recovery test level1), stature and lean body mass were measured. The significant difference among each category was analyzed by ANOVA and Tukey’s test. Then comparison between “Elite” and “Sub-elite” players was analyzed using Student’s t-test. Statistical significance was p<0.05.

Result and Discussion
In our study, Elite players in A and U16 were significantly faster in 40m sprint (Elite vs. sub-elite; 6.08±0.20 sec. vs. 6.25±0.26 sec for A, p<0.05; 6.20±0.22 sec. vs. 6.43±0.21 sec. for U16, p<0.01) and agility (11.72±0.23 sec. vs. 11.95±0.29 sec. for A, p<0.05; 12.31±0.30 vs. 12.75±0.39 sec. for U16, p<0.01). Moreover, in all categories, elite players had stronger 5 step bounding power than sub-elite players (10.70±0.45 m vs. 10.13±0.40m for A, p<0.001; 10.33±0.66m vs. 9.69±0.36m for U19, p<0.01; 10.31±0.32m vs. 9.91±0.38m for U16, p<0.01). These tendencies have been reported in the male soccer players (Gil et al. 2007; Reilly et al, 2001; Tsukoshi and Asai, 2010). Thus our results might imply the highly demand for the speed, agility and power in female elite soccer players’ selection process as well as male footballers.
On the other hand, when we compare motor abilities among each age category, there was no significant difference in 40m sprint time among three categories. This result may be explained by the general development of sprint ability because general girl’s 50m sprint ability tend to complete around 12 years-old (Minister of education, culture, sports, science and technology-Japan, 2009). In contrast to the development of sprint ability, adult and U19 (, 10.00±0.61m) players tend to have better agility (11.87±0.29sec. for adult and 12.02±0.30sec. for U19) than U16 (12.52±0.40sec.) players. This result may imply that agility develops rapidly after 16 years old, and this development is not necessarily accompanied by development of speed and power.
