The purpose of this study is to evaluate “Speed Uchikomi” as a form of strength training. We measured the following variables to evaluate the efficiency of this training, the heart rate according to the different pace of uchikomi, and the percentage of maximal oxygen consumption calculated from the heart rate and RPE. Endocrinological data, such as plasma lactic acid, ACTH and GH levels were also measured. The results were as follows: 1) We inferred from the cardiorespiratory response that “Speed Uchikomi” exceeds 70% maximal oxygen consumption when the frequency is more than once every 1.5 seconds. Therefore, when we use uchikomi as strength training, it should be done at a frequency of more than once every 1.5 seconds. 2) A gradual increase in the plasma lactic acid level, depending on the uchikomi frequency, was observed. “Speed Uchikomi” with a rate of more than once every 1.5 seconds gives a higher value than that of the lactate threshold or onset of blood lactate accumulation. From its energy metabolism, “Speed Uchikomi” is effective as endurance training. 3) “Speed Uchikomi” with a frequency of once every second increased the plasma ACTH level compared with the resting level. In other words, it is suggested that uchikomi which is a basic judo practice, has a significant influence on the endocrine system. 4) After performing “Speed Uchikomi” at the rate of once every second, the plasma GH level increased higher than the resting level, which means it has an anabolic effect. 5) The training rate of once every second is very exhausting and is expected to be more efficient than training at a rate of once every 1.5 seconds, but training like this without planning also carries a risk of overworking.

1995年の幕張大会以来、8年ぶりの世界柔道選手権大会が、4日間にわたり大阪市で行われた。 夏以来、陸上、水泳などの世界選手権が続き、日本選手の成績が即アテネ五輪出場権に繋がることもあって注目された。 柔道でも、井上康生をはじめとする日本選手の活躍が功を奏してか、最終日にはテレビ視聴率が最高の24.7%に達したというから、多数の日本人が柔道の醍醐味に魅了されたことだろう。 ...

「お帰りなさい、アテネへ」の標語のもと、オリンピックは108年ぶりに生誕の地アテネに戻り、柔道競技は開会式翌日の8月14日から20日にわたり開催された。試合はアテネ市の北部郊外に新設されたアノ・リオシア競技場で、毎日男女各一階級ずつが軽い方から行われた。 ...
