In archery, highly reproducible release is required during shooting to get a good score.Shooting in archery consists of eight different techniques. The last phase of these techniques is follow-through, which all eight have in common. The purpose of this study was to investigate the relationship between the muscle activity at follow-through and performance. In ten healthy archery club members, we recorded the muscle activity of six regions from both sides of M.deltoideus (pars acromialis), M. trapezius (pars ascendens), M. trapezius (pars descendens) by means of electromyogram. Integrated electromyograms of 1 second each at the aiming phase and the follow-through phase were calculated in order to evaluate this technique. The results obtained in this study were: 1) The skilled archers sustained high level (above 80%) muscle activity in the follow-through phase. 2) A significant correlation (r=0.791 r<0.05) was observed between the muscle activity on the draw side and the best score in a single round.3) The performance in archery was effected by the continuation of muscle activity in the shoulders, the neck and the back at follow-through. The continuation of muscle activity in the draw side seemed to be especially significant for archery performance.

Obesity is a condition resulting from excess body fat, and is associated with several risk factors for chronic diseases in later life. Hence, the prevention of obesity is a public health priority, with much of the concern focusing on childhood and adolescence. Recently, body mass index, calculated as weight divided by height squared (BMI, kg/m^2), has been widely used as a surrogate measure of adiposity for children and adolescents, and international age- and sex-specific cut-off points to define overweight and obesity have been proposed. Various surveys using the international BMI criteria have revealed that the prevalence of child obesity is accelerating throughout the developed world. However, BMI is a measure of excess weight relative to height, rather than excess body fat. The interpretation of BMI among children and adolescents is further complicated by the changes that occur in weight, height, and body composition during growth. There is a now a considerable body of evidence that during the growth stages, weight increase is frequently due to an increase in fat-free mass rather than fat mass. Therefore, application of the BMI norm to define overweight and obesity in children and adolescents should be done with caution. Furthermore, it is necessary to be aware that adopting an international standard for a specific population may introduce error because the relationship between BMI and adiposity is race-specific. For this reason, it is expected that race-specific standards of BMI with additional body composition-related information for children and adolescents will become available in the future to ensure reliable assessment of adiposity levels.

Until about 1920, swordsmanship was known as kenjyutsu or gekiken (gekken). Now, however, it is well known as kendo. This article attempts to clarify the reasons why kendo took the place of kenjyutsu. As the Japanese Ministry of Education first adopted gekiken in 1911 as a field of gymnastics, the Ministry ran a special school for swordsmen selected from middle schools across the entire country. Such a move was necessary because most swordsmen were not qualified as school instructors. Fortunately, a book written by a participant who recorded the lectures from this special school remains. From the manuscript, it is clear that, despite the fact that swordsmanship which consisted of fencing with bamboo swords was renamed gekiken, the Ministry instructed that the aim of swordsmanship practice was not to advance its techniques, but to build up spiritual endurance. A lecturer at the school, Sasaburo Takano, the first swordsmanship instructor at the Tokyo Higher Normal School, did not comment about the naming of swordsmanship, because he used both the terms bujyutsu (martial arts including kenjyutsu) and budo (martial arts including kendo) to describe the relationship between practice and the aim of martial arts. However, it is very interesting that another lecturer at the school, Michiaki Nagai, who was the only professor of gymnastics, argued that because the characters geki and ken emphasised technique over spirituality, gekiken should not be used at all. Thus what he emphasised was not gekiken but kendo.

Michiaki Nagai, the only professor of gymnastics (now known as physical education) at Tokyo Higher Normal School, was the only person who maintained that the aim of kendo (swordsmanship) should be not simply to advance its techniques but to build up spiritual ability through swordsmanship practice, taking the place of gekiken, a part of kenjutsu (swordsmanship), which was hitting practice with a bamboo sword. He first suggested this idea at the first special school for swordsmanship instructors selected from middle schools across Japan, held by the Ministry of Education in 1911. The aim of this article is to clarify when Nagai decided to change the name from gekiken to kendo by researching all of his articles and books describing martial arts, including swordsmanship, published from 1909, when he returned from abroad study, to 1915, when he wrote the foreword for kendo, the first great reference book for instructors, written by S. Takano, the swordsmanship instructor of the School. It is concluded that because Nagai did not have any idea about the name for swordsmanship with a bamboo sword at the beginning of his research, he used gekiken as the subject name for the School. However, he decided to use kendo instead of gekiken in August 1910, when the School adopted kendo as the subject name. As soon as the Ministry adopted gekiken as the official term for the school subject in July 1911, he acted publicly to use kendo for the School, in spite of the decision of the Ministry.
