We aim to clarify relationships between longitudinal changes in aerobic and anaerobic energy metabolism capacities and training in well-trained 800-m runners, and to identify strategies for effective 800-m training. Eight male middle-distance runners (800-m seasonal best time, 1′53″7±1″6) participated. Their 800-m running performances were set the best competition time in April-June and July-November, and calculated average running velocity. Three running tests on a treadmill were conducted to determine aerobic (maximal oxygen uptake [VO2max], lactate threshold [LT] and running economy [RE]) and anaerobic (maximal accumulated oxygen deficit [MAOD] and maximal blood lactate accumulation [LAmax]) energy metabolism capacities in July and November. Δ (%) represents changes in 800-m running performance and aerobic and anaerobic energy metabolism capacities. Training during this period was used to evaluate length of training time, and training ratio by three intensities; below the LT (zone 1), at or above the LT and below the VO2 max (zone 2) and at or above the VO2max (zone 3). Δ800-m running performance showed a positive tendency relationship with ΔRE and ΔLAmax ( r=0.67 and 0.70, respectively), and a negative tendency relationship with zone 1 training ratio (r=-0.70). Further, ΔRE and ΔLAmax were negatively associated with zone 1 training ratio (r=-0.90 and -0.79, respectively), and positive associated with zone 3 training ratio (r=0.79 and 0.75, respectively). Thus, improved RE and/or LAmax may improve 800-m running performance, and increasing high-intensity (>VO2max) training during a competitive period can improve these energy metabolism capacities.

This study focused on the takedown movements of female Japanese World Champion wrestlers in competition. Take down time which conducted from touching leg to getting point and these movements of two World champions were compared with those of other of other high level athletes.     As a result, World Champion had much higher number of effective takedown and much shorter the takedown time than other wrestlers. The following four findings were obtained as characteristics of a successful takedown movement. 1)Stayed in a forward leaning stance. 2)Head direct movement toward trajectory with little up and down motion. 3)The step back (jab step) of the trail leg was short. 4)Takes a leg attack with the opponentʼs loss of balance.     It is thought that a practical application of these findings could result in more effective coaching and training.

This study delineates the common characteristics of pitching motion in professional baseball players (Top and Minor groups) by focusing on their upper body. With an aim to gain insight into the development of athletic abilities, the pitching motion of the Top group was compared with the Minor group, resulting in the clarification of upper limb issues in the Minor group and amateur pitchers. The subjects were 47 pitchers belonging to the Nippon Professional Baseball (NPB). The experiment was a fastball pitch with maximum effort. The analyzed trial was the highest ball velocity (average ball velocity 38.9 ± 1.8 m/s). Post-analysis, the following commonalities and differences were identified. (1) There is a commonality in the sizeable external rotation of the shoulder joint during MER (Maximum External Rotation), which is considered a factor in pitching speed compared to amateur pitchers. However, after evaluating the professional baseball pitchers, it was suggested that this movement had a low influence on the ball velocity. (2) There was a commonality in the movements in which the maximum shoulder horizontal adduction angular velocity was more significant than the upper trunk angular velocity. (3) However, in terms of differences among professional baseball pitchers, the Top group pitchers had a greater horizontal adduction angular velocity of the shoulder joint during MER and a more significant extension angular velocity of the elbow joint during REL (Ball Release) by suppressing the forward tilt angular velocity of the trunk during MER.

The purpose of this study was to identify the game performance indicators associated with victory in men's handball from elementary school students to university students in Japan and to elucidate the age-related characteristics and changes in game performance in a cross-sectional manner. We analyzed the performance in attack and their corresponding match outcomes in 53 matches at Japan's national championships of various age groups (elementary school students, junior high school students, high school students, and university students). We obtained the following outcomes: (1) The winning team is excellent in the attack efficiency, the shot frequency, and the shot efficiency. (2) In the elementary school age group, neither the shot frequency nor the shot efficiency is a performance indicator that independently affects the match outcome. In the junior high school age group, the shot frequency and the shot efficiency affect the match outcome. Since the shot frequency is high for all the teams in the high school age group and the university age group, only the shot efficiency affects the match outcome. (3) The efficiency of an attack, especially in the organized attack phase and in a 6:6 situation, becomes increasingly more important in older age groups.

In this research, we focused on continuous rapid movement and clarified the actual condition of dancers breathing. In addition, we examined differences in breathing due to differences in experience years, targeting female college student dancers with various dance experience history. As a result, the respiration of a dancer with a history of more than 15 years of experience was 80% the same breath, the difference in respiration became different as the years of experience decreased. In addition, the possibility that the dance genre experienced in the past and the experience of other sports was influenced was considered as the characteristic of respiration.

The purposes of this study were to clarify the influence of physical strength on throwing distance, and to estimate strength requirement for each target throwing distance of discus. The questionnaire method was used to investigate parameters about morphology and physical strength for 114 male discus throwers. Pearson’s correlation coefficient was calculated to investigate the relationships between the parameters and throwing distance. Then, multiple regression analysis was carried out to clarify influence of the parameters on throwing distance. As a result, all parameters correlated significantly to throwing distance. The parameters of morphology to have great influence on throwing distance were span of arm and body weight. The parameters of physical strength to have great influence on throwing distance were backward over head shot throw, snatch, standing five steps jump, 30m dash, in descending order. In addition, physical strength requirement corresponding to throwing distance of discus was gained by estimating the standard value of each parameter from the regression analysis. Strength requirement shown in this study has a high practicality for coaches and throwers in planning training programs and setting goals.

This study sought to clarify the impact of game format differences on goalkeeper play through a comparative examination of goalkeeper play in games of 8-a-side soccer in Japan and 7-a-side soccer in Catalonia, Spain, two formats used respectively in each region in competitions for players aged 12 years and under. At the same time, it offers a discussion of future approaches to goalkeeper coaching.     This led to clarification of the following:     1) Given that goalkeepers in both countries take the offensive more frequently in game formats with fewer players, such formats appear to be effective for promoting offensive plays by goalkeepers.     2) When the goalkeeper is in possession of the ball, whereas Japanese players have a strong tendency to choose long kicks such as side volleys, Spanish players have a strong tendency to elect to throw the ball to attempt a more reliable relay.     3) Spanish goalkeepers have a strong tendency to be involved in build-up play with passes and support.     4) On goal kicks, whereas Japanese players have a strong tendency to choose long kicks, Spanish goalkeepers have a strong tendency to make short passes to teammates who are in a position to advance the ball.     5) In terms of goalkeeper defense, whereas Japanese players stop fewer shots and make more plays to cover the space behind the defense line, Spanish players stop more shots and make fewer plays to cover the space behind the defense line.

The purpose of this study was to clarify the relationship between the level of organizational commitment and the social power of sports coaches, and to identify the social power that coaches can rely on to increase organizational commitment based on that relationship. An online-questionnaire was used in this study, and 464 basketball players enrolled in the Division 1 of Kanto Collegiate Basketball Federation was a target for this study. A total of 166 basketball players participated in a self- administered questionnaire between the 29th of July and the 9th of August, 2020 (response rate: 35.8%). A multiple regression analysis was performed with the level of organizational commitment (Allen & Meyer, 1990) as the dependent variable and the five types of power resource (Mori, 2005) as the explanatory (Independent) variable. It was suggested that in order to increase organizational commitment, it is important for coaches to provide guidance that relies on the passion for coaching power and the expert powers.

The purpose of this study is to identify the characteristics of the overhand pass in beach volleyball (BVB) by comparing it with the overhand pass in volleyball (VB). The following results were obtained:     (1) In the pull phase, wrist dorsiflexion occurred in VB. On the other hand, in BVB, the elbow was bent in addition to the wrist dorsiflexion. This finding suggests that there is a difference in the buffer action of the elbow between VB and BVB.     (2) In the push phase, the maximum angular velocities of knee and ankle joints were not during VB but during BVB. This finding suggests a timing difference in lower extension between VB and BVB. And, the largest angular velocity of the upper limbs was seen in the wrist during VB, whereas it was seen in the elbow during BVB. This suggests the segment of the body that accelerates the ball in VB is different from that in BVB. Besides, the timing for extending the upper and lower limbs differs in VB but is comparatively near in BVB.     These results suggest that the characteristics of BVB involve the buffer action of the ball with the elbow in addition to that with the wrist, and the acceleration of the ball with the knee and ankle and the simultaneous elbow extension.
