Abstract: The Purpose of this study was to investigate if unstable function shoes would changed the walking posture and gait after 8-week by wearing MBT. There were 18 women 42-year-old and wear MBT 8 hours per day, 5 days per week. And the average steps were 6784 everyday. They did walk 5 trials successfully via 10 Vicon high-speed infrared cameras and 2 Kistler force plates. The kinematics result were included GRF(BW), Tibia/Floor angle(degree), Hip angle(degree), Forward speed(cm/s), One step time(s) and One gait time(ms). The hip angle means flexion-extension angle at mid-stance while walking; positive value means hip flexion and negative value means extension. Most data showed no significantly different except the GRF, the post higher than pretest. The walking posture at mid-stance showed no significantly change beneficial result after wearing MBT for 8 weeks, but the step and forward speed showed accelerate.

High heels are now commonly used among women because of its high-fashionability. Furthermore, high heels have became a part of business fashion and for this reason, there are many women who wear high heels with feeling pain and fatigue on lower limb. According to the previous study, it is reported that more than half of women complain a range of symptoms including foot pain and shoe sore even when they wear competitively-low heeled shoes. Although women should avoid wearing high heels for many hours, choosing correct shoe size that fits to own foot and improving the gait could prevent pain and fatigue. In this study we focus attention on the gait of walking with high heels and purpose a development of an in-shoe device to measure a sole pressure in high heeled shoe. The device is mainly composed by some pressure sensors and microcomputer. It can be used to monitor plantar pressure and is expected to contribute to improving the women's gait during walking in high heels.

The purpose of this study was to investigate the effect of compression shorts on jump performance (height), hip joint angle, hip joint moment, and hip joint stiffness during drop jumps from three different heights. Twelve male basketball players were recruited for this experiment. All were requested to wear two types of shorts [nylon-elastane compression shorts (CS) vs. loose fitting shorts (as a control condition, CC)] to execute three trials of maximal effort drop jump from each of height (30, 45, and 60 cm) from a custom-made platform. A VICON motion analysis system (120 Hz) and two 60 × 90 cm force plates (Kistler, 1200 Hz) were used to collect kinematics and kinetics data simultaneously. The commercial compression shorts adopted in the present study did not improve jump height during drop jumps from three heights. However, the tight and compression fit results in a great change in hip joint kinematics and a considerable moment generated by the hip both in flexion and extension phases during 60 cm drop jumps. Future research is warranted to investigate this effect in jumping events (e.g. high jump and long jump) and further confirm the role of compression apparel on joint stiffness as well as performance benefits.

In many sports, the jump movement is one of the important basic movements. It is useful to analyze the jumping ability dynamically to perform a training effectively. However, the opportunity of the dynamic measurement is limited in daily training because expensive measuring equipment represented by a force platform is necessary to quantify the jump movement dynamically. Therefore. For this problem, this study aimed to propose the inexpensive and portable apparatus for jump movement. The Wii balance board (WBB, Nintendo Co., Ltd.) was used as force sensors to measure a jumping force and weight distribution. The WBB has four strain gauge force sensors under each corner of the board. The measurements by these sensors were transmitted to a Windows PC via Bluetooth wireless technology. The signal processing and screen display were performed using the custom-written software with Actionscript 3.0 (Adobe systems Software Ireland Ltd.). The vertical ground reaction force (vGRF) was calculated by summation of the measurements of four sensors. The position of center of pressure (COP) was computed by the weight mean of four force data. The force-time curves of vGRF and path trajectory of COP were depicted on a PC monitor in real time. According to Yamamoto and Matsuzawa (2013), a WBB can take measurements with precision of less than 2%. Using this system, athletes and coaches could confirm the force exerted (vGRF) and the weight position (COP) in real time during training. The proposed system was constructed only with a PC, a WBB, and a Wii Remote controller. The apparatus necessary for this system would be obtained for approximately USD$100 except a PC, and total weight was less than 4kg without a PC.

It is well-known that obesity can lead to various diseases. According to the World Health Organization (WHO), obesity in the world has doubled since 1980. Obesity is no longer a problem in developed countries alone. Lack of exercise is considered to be a major factor. Typically, people go running or go workout at a training gym to get their exercise. Recently, a lot of people watch and follow exercise videos at home at their own leisure. However, in many cases, joint angle and position of the body while exercising are major factors to consider in order to maximize the effect of an exercise. Where an exercise instructor is not around to point out the critical points to follow while exercising, it is often difficult for people exercising on their own to achieve good results. In some cases, wrong methods of exercising can result to an injury. In this study, we propose a system which enables the person exercising to see his/her image exercising and at the same time watch the exercise video. We will have two groups. One group will exercise following the exercise video only. The other group will follow our proposed procedure. We will make them exercise three times for one minute. After that, we will use an image analysis software to compare the joint angles and speed of movement of those exercising. In this way, we will be able to verify the effect that simultaneously watching oneself exercise while watching an exercise video has on the quality of exercise movements.

To promote exercise participation and increase physical activity level is an important issue in industrialized countries to reduce the risk of metabolic disease. As dramatic changes in modern lifestyle, the new technology gives unique opportunities to overcome barriers of physical activity. The purpose of this study was to identify the Smartphone application coaching program can increase physical activity level and exercise participation frequency. Participants were divided into three groups of control (ExA, n=23), smartphone exercise group (ExB, n=30) and exercise with self-recording dairy group (ExC, n=17). Before and after 6-week of experimental period, their physical activity level were assessed by accelerometer and completed International Physical Activity Questionnaire (IPARQ). Participants were encouraged to 30-min dairy exercise and check their exercise participation via smartphone application and self-recording dairy by their groups. Comparisons between groups were made using two-way ANOVA with repeated measures and t-test for exercise participation. The exercise participation rate of smartphone group was significantly higher than self-record group (26 times Vs. 16 times, p=0.039). The physical activity level of smartphone group was significantly increased comparing with control group (p=0.037) but there were no significant difference between smartphone group and self-record group (p=o.411). Smartphone exercise coaching program was a useful tool to increase in physical activity level and exercise participation numbers. Self-recording dairy also can be used to promoting physical activity level and exercise participation. Future studies need to examine more exercise promoting content in smartphone application could resulting in increasing physical activity and exercise participation rare over the long term period.

Unilateral spatial neglect is a behavioral syndrome occurring after a right-hemisphere stroke. Treatment for spatial neglect focuses on cognitive rehabilitation that uses prism adaptation therapy as one approach. However, this therapy has limitations both in terms of its narrowness of focus and duration of the beneficial effects. This study was carried out to evaluate the effects of pointing practice on walking performance looking through a right-left reversing prism. The participants were fourteen right-handed healthy persons with a mean (SD) of 26.3 (7.1) years. They put on prism glasses causing right-left reversal of the visual field, and were asked 30 times to point to targets placed 3m in front using a laser pointer. Timed up and go (TUG) test and walking around the edge of a 3m square (SW) were used to measure walking performance and were evaluated 3 times (before, immediately after and 5 mins after the pointing practice). The required times, both TUG and SW, recorded immediately after and 5 mins after the pointing practice were significantly shorter than that of before. In particular, the deviations from the walking path in SW showed significant differences between the values recorded immediately after and 5 mins after the pointing practice and that of before. Improvement of walking performance with a prism after the pointing practice might have facilitated adaptation between mediated proprioceptive perceptions and visual information. The efficacy of single-session prism adaptation suggests general improvement of daily activities in patients with unilateral spatial neglect.

Judo is a combat sport that requires a high level of various types of physical fitness. In particular, strength and power of the upper body is required. Recently, various sports athletes use battling rope exercises. In their training, battling ropes are a relatively new exercise that improves the strength, power and endurance of the upper body. The purpose of this study was to investigate the effect of rest interval time on the physiological response during battling rope interval exercise of judo players. Ten university male judo players participated in this study. The exercise time was 20 sec and interval times for rest were 15 sec, 30 sec, and 60 sec. Heart rate was measured during exercise, and blood lactate was measured immediately, 3 min, and 5 min after exercise. Our results suggest an effective protocol for the use of battling rope interval exercise in the training of judo players.

The aim of the present pilot study was to investigate the effect of central fatigue induced by high-intensity interval exercises on the visuospatial attention and reaction time. Six intercollegiate male athletes (age 19.7 ± 8.3 years old, weight 67 ± 9.1 kg., and VO2max 59.6 ± 8.8 mL/kg/min ) underwent high-intensity interval exercises (20-min sprint in 65% VO2max; then 2-min sprint in 85% VO2max and 3-min sprint in 65% VO2max, repeated 8 cycles) to elicit peripheral and central fatigue. The covert orienting of visuospatial attention task (COVAT) was used to evaluate the visuospatial attention and reaction time before and after exercise. The inhibition reaction time in upper limbs and all limbs was significantly worsen after the exercise, indicating a decrease in visuospatial attention. There was no significant difference in simple reaction time. The present findings suggested that the high-intensity exercise may decrease the visuospatial attention performance, but have no effect on reaction time. The COVAT method appears to be a suitable method to measure the changes in visuospatial attention after exercise in athletes.

The purpose of study was team sports, it is thought that the psychological factor at the group level is important as well as a personal level. One of the psychological factors at the group level includes "a feeling of group effect". Kawazu and others (2012) and Serizawa and others (2008) state that a feeling of group effect affects the competition results and the performance. However, it is not supposed a study in a specific event. Therefore, in this study, I paid my attention to a feeling of group effect of the high school volleyball player and was intended that I clarified the characteristic. I performed inventory survey for 477 high school volleyball player men and women (208 boys, girl 269) using CES-JHSA (feeling of group effect standard for member of high school athletic club).As a result of analysis, significant difference was recognized in "ability display", total understanding and showed the score that non-regular group was higher in than regular group again. Because oneself thinks that it is possible than regular group in the non-regular group having few opportunities to participate in a game without awareness, recognition being still done by an opponent how much is used, it is guessed when a difference was seen in a feeling of group effect. Furthermore, a feeling to want to become a regular is strong and is guessed when overconfidence that oneself can contribute to the team may influence a feeling of group effect.

It takes a long time to correct habitual errors. Athletes sometimes revert to their old, incorrect movements when they are in high-pressure competitions. The purpose of this study is to examine the effectiveness of rapid movement corrections and performance improvement through Lyndon's (1989) old way/new way, which can be used to learn a new skill by reviewing video recordings of their own movements and then identifying the difference of movements by contrasting the old, erroneous ways to the new, correct ways. A weightlifter, who has been working to correct a technique problem, used this method one month prior to a game. To achieve movement correction in the quickest way possible, the following procedures were completed: error analysis, recognition of the erroneous movements, correction of the erroneous movements, identification of the erroneous movements and the correct movements, verifying the desired movements, and reviewing the games. As a result, Athlete A corrected 100% of his movements at a game, which is verified in the video recordings. His record shows that snatch (S): 100 kg and jerk (J):120 kg at the game; the results were close to his self-record. Athlete B corrected 100% of his movements at a game, which is verified in the video recordings. His record at the game was (S): 93 kg and (J):103 kg; he made a new self-record. The evidence suggests that the athletes who used old way/new way corrected the erroneous movements efficiently, and their improved abilities were demonstrated with the corrected movements at the games. Therefore, this method is considered to work effectively.

The purpose of this study was to examine a method of psychological conditioning for competition. Specifically, the effectiveness of a method to create the optimal psychological condition for competition by monitoring the emotional state was verified. The emotion monitoring applied IZOF theory (Hanin, 1997) was conducted by controlling the antecedents of emotions.
The subject was a male cross-country skier of Japanese top-leveled. First, we identified performance-related emotions by comparing the emotion-profiles between the best performance and the worst performance in previous season. So, we considered about the antecedents of the emotions and tried stabilizing the emotion states by managing the antecedents of the emotions.
There are clear differences in emotion profiles between the best performance and the worst performance. It was found that "vitality" and "exhausted" greatly influenced to performance. "Good preparations", "take a break properly" and "nutritious meals" were considered as the antecedents of "exhausted". The controlling of the antecedents was conducted for competition. As a result of the managing in the competitions, it seemed that the controlling the antecedents contributes to stabilize the emotion states and that leads to enhance sport performance. These results and subject's introspections suggested that it was useful to manage the antecedents of the emotions for psychological and physical conditionings for competition.

To obtain suggestions for effective coaching, the present study aimed to investigate the relationship between the mental condition of judoka during preparation for a competition and coaches' evaluations of their performance in that competition. The Profile of Mood States – Brief Form was used to objectively determine participants' mood states. Coaches were asked to rate the participants' competition performances on a 10-point scale ranging from 1 (completely unable to perform) to 10 (performed extremely well). Participants with lower performance rating scores (the low score group) had decreasing tendencies regarding mental condition, while those with higher scores (the high score group) showed increasing tendencies. The present findings suggest that it is necessary for coaches to adequately evaluate the mental condition of judokas in the run up to a competition.

Collective efficacy (CE) is a key factor for understanding the function of organizations or groups. Most researchers advocate that CE has a close relationship with performance. Previous studies in sport psychology, both domestic and international, have been confirmed the high utility of the concept of CE. However, these studies have not derived valuable findings with potential application in the field of sports coaching. Especially, it is necessary to examine that identification of resources affecting CE and gather the longitudinal data. Therefore, the purpose of present study was to investigate the changes in CE and factors that may affect CE. The participants were 38 varsity athletes (19 women, 19 men) of 3 different basketball teams. CE was measured by the Collective Efficacy Scale for Basketball (CESBO) developed by Ikeda et al. (2013). Team performance was measured using indices and equations in "notational game analysis". The questionnaires were administered 4 to 8 times during the Kanto Collegiate Basketball Leagues in 2013. Repeated-measures ANOVA and Bonfferoni post hoc test showed that the scores of CESBO subscale were significantly increased or decreased in response to the influence of performance, with larger effect sizes (p < .05).

The purpose of this study is to examine influence of teammates on motivational climate of high school and college baseball teams, to find relationship between motivational climate patterns and intra-team competition and to contribute to improve teamwork and motivation of team members. The study was done on 333 male athletes (153 high school players with their age of 16.30 ±0.74 years old; 180 college players with their age of 20.19 ±1.35 years old) belonging to the 4 high school and 5 college baseball teams in Hokkaido. The research was carried out to ask each baseball team to fill out a questionnaire that I had made for the study. The contents in the questionnaire were based on their individual profile, such as ages, gender, and so on, and some questions to measure motivational climate of the team and to understand the interaction among the teammates. From the research, I found the following results: In case some players in the teams show unfavorable attitudes toward the other teammates or some players who are physically gifted don't feel the need to practice, these negative factors often influence strongly the players' performance climate. Intra-team competitions develop not only performance climate but also mastery climate. There is a possibility that promote the autonomy of the players by teammates to help each other progress. This suggests that improvement of both mastery climate and performance climate is lead by consequence of effort to produce higher performance, not comparison of one's talent.

Lin Dan and Lee CHongwei are the most outstanding men's singles badminton players in the world. We analyzed Lin and Lee in the recent 3 games by observation, the men's singles final of 2010 Asian Games, 2011 World Championships and 2012 Olympic Games. We found that, although Lin and Lee were different in style of play, Lin Dan mainly used for pressing Lee to the backcourt and got chance to assault, LEE more inclined to create opportunities near the net for assault. But they were very similar in the way of scoring.
1.Lin and Lee mainly created opportunities to attack for scoring at the forecourt near the net, the proportion is over 50%. Combined technical methods were as follows: drop and net shot or push, drop and attack, or push and attack.2.Secondly the backcourt, combined technical methods are as follows: attack and net shot or push or cross clear,gently attack and assault. 3.The common characteristics of the above methods showed that, aggressive consciousness and the coherence of technology combination, changing the rhythm and changing speed of action for sudden attack were the important factors.

Recent studies have used a notational analysis to analyze performance in ball sports. In generally, a notational analysis could assess the total tactical behavior and the important aspects of the game to evaluate the single actions. In order to gain deeper insight into the tactical behavior of the individual and team, it is necessary to record the multiple tactical actions and to analyze the sequence of attacking play actions in chronological order. This study used the sequential analysis to examine the attack aspects of offense set-play in team handball. There were analyzed the offense set-plays of women's teams in 2012 London Olympic games. We categorized 5909 attacking play actions out of 1631 offense set-plays, were performed by 25 games from five nations. The attacking play actions during the offense set-play were classified into the 12 types of attacking play actions, according to the moving and throwing directions on previous player and the attacking direction of player while receiving a ball. We lined up the multiple attacking play actions in a chronological order during each offense set-play. The sequence of attacking play action during offense set-play was divided into the sequence codes of two, three, four, and five characters (alignment). In this study, the specific sequence codes of combined multiple attacking play actions in offense set-play existed to perform the sequence analysis in team handball. This new analysis method using sequence analysis might provide the evaluation of the characteristic of the offense set-play in team handball and the specific offense set-play for each team.

The purpose of this study is to reveal training regimens in terms of the contents and methods of shooting-play in Serbian and Croatian women's handball teams. Regular training sessions of those teams during the competition period are selected for comparison with the previous study (Japanese, Danish, and Norwegian teams). As the results of previous study, the Danish and Norwegian training sessions were covered the reaction of the defender and the connections of shooting-play-elements and attack processes. On the other hand, the Japanese training sessions included more time practicing individual techniques, and the women tend to practice separately with regard to shooting-play-elements and attack processes. The researches in Serbia and Croatia will be done until June 2014. So the results of this study will be presented at the conference.
