Abstract: “Arrest”, one of the four martial arts techniques, has the effect of pulling one hair and moving the whole body; It also has the power to divide muscles, bones, grasping meridians and pulse. This paper focuses on the experimental method, logical analysis, literature research and other methods to study the physiological mechanism of “Arrest”, which is not only conducive to a clear explanation of the biomechanical mechanism of “Arrest”, but also conducive to provide scientific method guidance for the actual combat training of “Arrest”. The results prove that: 1) Acupoint grabbing will affect the brain waves, which will cause the body to spasm; 2) Through the Comparative study with the brain wave waveform of the body's epilepsy caused by the disease, the brain wave generated after acupoint arrest is different from the waveform produced by epilepsy lesions, and it is concluded that the physiological changes of the body after acupoint arrest are similar to the pathology of epilepsy; 3) By observing the rhythm changes of different waveforms of α, β, θ, and δ of the same subject before and after the experiment after grasping acupoints and non-acupoints, it is concluded that the acupoints have a greater degree of abnormality in human brain waves.

Abstract: Ankle injuries are very common in basketball, with 45% of basketball players experiencing at least one sprain at any point in their career and 53.7% of missed playtime is caused by ankle injuries. These injuries can be caused by overworking muscles and causing them to reach maximum tension and soreness. When this happens, the surrounding ligaments and tendons are more susceptible to injury since the muscles that they hold together are weaker and don't function at full strength. The purpose of the study is to understand if athletes will benefit from taking supplements of Branched Chain Amino Acid (BCAA), to prevent ankle injuries from high a vertical mobility sport like basketball, which includes vertical jumps, layups and re-bounds. Using a combination data collected from control group vs placebo group we proved that BCAA reduces muscle soreness. This is proved by lower soreness scores, and lower values of Creatine kinase (CK) in the blood by the control group that took BCAA. We then proved there is a direct linkage between soreness and muscle fatigue by referring to a study conducted on lateral muscle of Rabbits, which show muscle fatigue, cause soreness and resulting in lower energy production and instability in function, leading to Injury. Based on the study, we comprehensively conclude that BCAA can help reduce risk of ankle injury by reducing muscle soreness and fatigue in basketball players, thereby promoting stable lateral and ankle dorsiflexor muscles.

Abstract: This study was conducted in Japan, where Judo has become a part of compulsory education in junior high school. The studied the experiences of 254 junior high students learning Judo for the first time were examined with respect to the value of learning traditional behavior, including respectful attitudes and manners toward the fighting opponent; their impression of the sport, such as whether it is fun or scary; and how these change through the learning process. The classes were planned to include five sessions. The main learning contents were structured with an emphasis on teaching "knowledge," "skills," and "attitudes."". The students were asked to participate in a pre-class and post-class survey consisting of 26 items created by the authors to examine their psychological change. The results demonstrated that there were significant changes in the students’ responses to items such as “It is necessary to conduct Judo classes in Physical Education given how the sport is a unique culture of Japan” and “My impression of Physical Education classes is that they are ‘fun’.” In addition, their fear of Judo, such as having an impression that Judo lessons were “painful” and “scary,” also reduced. This study identified psychological changes in junior high school students’ perspectives toward the value of learning Judo and their impression of Judo lessons for those experiencing Judo for the first time. Its findings will contribute to enriching Judo instruction in junior high school and at Judo clubs with students around the same age.

Abstract: The ability to monitor and maintain player readiness and fatigue is paramount to the success of a basketball team over the competitive season. Countermovement jumps (CMJ) are a popular method of quantifying neuromuscular performance and readiness of athletes. Since conference play at the end of the season is when players are needed to perform at their best, a CMJ can also be used to monitor lower body fatigue. Previous research is inconclusive regarding the impact of a competitive season on player fatigue and readiness. The purpose of this investigation was to examine the changes in neuromuscular readiness and lower body power over the duration of a competitive season in male collegiate basketball players. CMJ data of nine collegiate basketball players, who played in all the conference games and conference tournament games, were analyzed. All players were assessed at the beginning of and throughout the season. Players performed CMJs twice each week. A players’ best CMJ performance and the preceding jump (so two consecutive jumps) were averaged for this analysis. In addition to jump height, time to take-off, average relative propulsive power, and modified reactive strength index (mRSI) were measured. Players either maintained or improved their vertical jump height over the competitive playing season. There was a significant increase in jump height during the 18-week period of competitive play. There was no statistical change in time to takeoff, over the 18-week period. Although 7 players improved their average relative propulsive power over the competitive season, there was no significant difference statistically. No statistical change was seen for modified reactive strength index. The results of this study did not see a decline in neuromuscular readiness or lower body power over the duration of a competitive season in male collegiate basketball players. Previous studies have reported a decrease in strength and power at the conclusion of the competitive season. Based on results from this study, the ability of the players to produce force quickly was not negatively impacted by games, travel, strength training and practice stress. Monitoring CMJ performance is a valuable method for coaches trying to maintain player’s neuromuscular readiness and lower body power during a competitive Division I basketball season.
