本研究は、大学生を対象に運動有能感に対する相対年齢効果の性差を明らかにすることを目的とした。対象はスポーツ実技科目を選択履修した男子1326名および女子1479名とし、質問紙により調査を行った。被検者には、運動有能感(17項目)、過去の体育に対する意識(5項目)について、「非常にそう思う」(5点)から「まったくそう思わない」(1点)の5段階で評価させた。生まれ月は、4群(4–6、7–9、10–12、1–3月)に分けた。運動有能感について、因子分析により共通要因を算出した。その結果、「身体的有能さの認知」、「統制感」および「受容感」に分類された。各因子得点を算出し二元配置(性別×生まれ月)を行ったところ、「身体的有能さの認知」においてのみ交互作用が示された(男子>女子、女子のみ4–6月>1–3月)。また、過去の体育に対する意識のうち、「球技種目が得意だった」について交互作用が示された(男子>女子、女子のみ4–6月>1–3月)。以上の結果から、大学生の運動有能感に対する相対的年齢効果には性差があること、その原因は過去の体育における球技種目にある可能性が示唆された。

The purpose of this study was to compare the age at which elite athletes started competition, and the age range for advanced athletic activities. The study included 914 athletes and candidate athletes (451 men aged 15-51 years and 463 women aged 14-55 years) who participated in the 2014 Incheon Asian Games. In addition, the study investigated the ages of 1,971 athletes and candidate athletes (992 men, 979 women) at previous Olympic Games (Athens 2004, Beijing 2008, London 2012, Rio 2016). The main results of the study were as follows. 1) There were significant differences among sports event categories in the age at which both male and female athletes started competition: scoring events (boys 6.8 ± 3.0 years, girls 7.3 ± 2.4 years), racket events (boys 7.2 ± 2.1 years, girls 6.4 ± 1.9 years), fighting events (boys 9.2 ± 4.9 years, girls 9.0 ± 4.0 years), ball games (boys 9.2 ± 4.9 years, girls 10.2 ± 4.1 years), record events (boys 12.3 ± 5.2 years, girls 13.5 ± 6.9 years), target events (boys 12.6 ± 6.4 years, girls 14.5 ± 7.7 years) and water events (boys 13.4 ± 3.9 years, girls 12.1 ± 3.9 years) (P <0.05). 2) There were significant differences among competition events in the period from the start of competition until participation in international competition and reaching a winning level in national competition: record events (6.7 ± 5.0 years) vs. ball games (9.6 ± 4.4 years) and scoring events (9.9 ± 4.2 years) for girls, target events (4.9 ± 2.2 years) and record events (6.7 ± 4.6 years old) showed lower values than scoring events (7.5 ± 3.9 years), fighting events (7.7 ± 4.1 years), racket events (8.2 ± 3.5 years) and ball games (8.7 ± 4.0 years) (P <0.05). 3) For both men and women, there were significant differences between competition systems in the age of participation in the Olympics: water events 28.4 ± 4.6 years, target events 30.3 ± 7.1 years and scoring events 31.1 ± 11.6 years for girls, scoring events 20.7 ± 3.3 years, racket events 23.6 ± 4.4 years, record events 24.2 ± 4.5 years. Compared with age, ball games 25.4 ± 4.4 years, fighting events 25.8 ± 3.6 years, water events 26.5 ± 4.8 years and target events 28.1 ± 6.3 years (P <0.05). The findings suggested that the age at which athletes started competition, the period from the start of competition until reaching top level, and the timing of participation in the Olympic Games may be affected by differences in competition type and gender.

The purpose of this study was to identify the biomechanical factors limiting distance and the jump technique in the maximum effort standing long jump. The limiting factors and jump technique were identified through an analysis of the relationship between patterns of joint powers in the propulsion phase of the standing long jump and maximum isokinetic strength of the lower limb. The participants were 11 male athletes specializing in different events. Isokinetic strength of the extensor muscles at the ankle (30 and 90 deg/s), knee (60 and 180 deg/s), and hip (60 and 180 deg/s) joints was evaluated by dynamometry. Joint powers in the propulsion phase of standing long jump were calculated by inversed dynamics methods using digitized two-dimensional coordinate data (50 Hz) and ground reaction force data (500 Hz). Pearson's product-moment correlation analyses were used to assess the relationships between jump distance, joint powers over the propulsion phase, and isokinetic strength of the lower limb joints. The results indicated the following.  1. The magnitude of the body center of mass velocity and whole body mechanical energy at toe-off were correlated with jump distance (velocity: r=0.857, p<0.01, energy: r=0.926, p<0.01).  2. Peak powers at the knee and hip joints over the propulsion phase, normalized to body mass, were correlated with jump distance (knee: r=0.767, p<0.01, hip: r=0.723, p<0.05).  3. Isokinetic extensor strength at the ankle, knee and hip joints, normalized to body mass, did not correlate with peak power at the corresponding joint over the propulsion phase. Also, only knee extensor strength at 60 deg/s was correlated with jump distance (r=0.652, p<0.05).  4. Knee extension torque at maximum knee flexion, which is used as an index of countermovement, was correlated with jump distance (r=0.836, p<0.01) and peak knee power (r=0.765, p<0.01). In one participant who had the highest ratio of peak powers over the propulsion phase to isokinetic strength, knee extensor power was enhanced by increasing the knee extension torque with countermovement and coupling of the arm swing to knee extension during the propulsion phase.  Therefore, although the jump distance depended on the lower limb joint powers over the propulsion phase, the power was not directly modulated by isokinetic strength. This phenomenon might be derived from strategies that enhanced lower limb power with countermovement and coupling of the arm swing to lower limb motion.

The authors have recently developed a system for analyzing the spin on a baseball (Koseki et al., 2007). In the present study we analyzed the spin pitched by a professional pitcher. He pitched eight different pitches, each twice, from official pitching mound. The image of ball in the period from just before to 500 ms after the ball release was taken with a high speed video camera at 1000 fps. English alphabets E, M, A, and I were marked on the ball for image processing. Feature points from the image stream were assembled into a set of linear equations that represents orientation change between consecutive two frames by rotation matrix R, and the direction of spin axis and spin rate were obtained. Both values varied considerably depending on pitches. The recording of spin was suggested to be valuable for training if the data could be combined with those of motion analysis.

The purpose of the present study was to clarify the influence of swing parameters by changing the hitting point in space in baseball batting. Twenty-eight skilled baseball players (12 professional and 16 universitylevel) participated. The participants were instructed to hit a ball that was tossed from 5 m away in the direction of the pitching mound. The balls were tossed to various locations with reference to the home plate. The participants were required to hit the balls in a specific direction according to the tossed course, i.e., a ball tossed to the inside of a home plate was stroked toward the same-field direction and one tossed outside of the home plate was stroked toward the opposite-field direction. The motions of the ball and bat during these attempts were recorded using a motion capture system operating at 500 Hz. The 3D coordinates of the ball center (hitting point) and the swing parameters included the speed of the head of the bat (bat-head speed) and the angle of the swing from a horizontal line (swing angle) measured immediately before ball impact and the time from the start of the swing to ball impact (swing time). These parameters were calculated in each trial. Analysis of a total of 644 trials revealed that the bathead speed tended to increase as the hitting point moved inside, forward, and low. Furthermore, the swing angle and swing time tended to increase as the hitting point moved inside, forward, and high. Stepwise multiple regression analysis demonstrated that the bat-head speed and swing angle were independently associated with (in the following order) the distance in the pitcher’s direction, the hitting height, and the inside-outside direction course (R2=.360 and R2=.589, respectively). These results suggest that the timing of swing initiation and bat acceleration during a swing motion are the main factors changing the swing parameters, and that in order to sharp hit a ball, it is important to impact the ball with the hitting point as close to the pitcher as possible.
