Japan [Objection] Drug abuse, most notably anabolic-androgenic steroid (AAS) use, in athletes is widespread. Some athletes who abuse these drugs worry about the side effects of the drugs, especially AAS. There have been publicly accessible websites managed by drug abusers that provide athletes information about drugs. We surveyed the state of drug abuse in sports in Japan by analyzing consultations on a bulletin board of one such website. [Methods] We accessed a Japanese-language website on it
... uage website on it that was presumably managed by drug abusers. Specifically, we accessed a bulletin board that drug abusers were using to communicate with each other. We analyzed the contents of all consultations on the bulletin board in 2015. [Results] Although there were 159 accesses in 2015. 142 ones of them were consulted about drug abuse. The efficacy of drugs was discussed in 23 consultations, the side effects of drugs in19, the way of doping in 62, and the selection of drugs in 7. Regarding the way of doping, steroid cycle was discussed in 24 consultations, injection in 5, (the time of) administration in 27, and dose in 5. As to side effects, there were gynecomastia in 3 consultations, and liver dysfunction in 2. Among those who posted items, 38 individuals were thinking to use drugs, 62 were using drugs at the time, and 8 had previously abused drugs. [Discussion] Drug abusers exchanged information about doping over the Internet in Japan, too. Due to the increasing number of drug abusers, it is necessary to have an official government system in Japan. Physical activity is thought to change the emotional state through the influence on monoamine in the brain.The relationship between psychological emotional change and amount of catecholamine secretion was not clear. We will clarify the relationship between change in emotional scale and change in catecholamine in blood. 39 general female students (aged 20.7±0.50 years old, height 160.0±4.4 cm, body weight 55.8±6.8 kg) were included in the survey. Blood sampling in this experiment was made 2 hours before the exercise, immediately after the completion of the exercise. The exercise took about 60 minutes in total, the contents of the exercise were at 50% V ・ O 2 max for 30 minutes using a bicycle ergometer, and 6 sets of 10 training with 1 RM 70% intensity using a leg press. V ・ O 2 max (PWC 170) and 1 RM were measured one week before this experiment. In psychological emotional change, elation improved significantly after aerobic exercise and after strength training. Dopamine was 11.4±4.8 pg / ml 2 hours before exercise, 22.3±9.0 pg / ml immediately after exercise, noradrenaline was 395.2±137.6 pg / ml two hours before exercise and 574.0±210.3 pg / ml immediately after exercise, (p<0.05). There was no correlation between the change in elation and the change in catecholamine, but there was a tendency that changes in elation was greater as physical fitness level was higher. Even though the relative strength was the same, it seemed that people accustomed to exercise tended to feel elation more easily.
