These rules generally apply to football players since the 1970s. "There is really no good reason to justify this opinion. There is no physiological basis for it," said John Bancroft, former director of the Kinsey Institute For Sex, Gender, and Reproduction Research in Bloomington, Indiana, as quoted from Bioedonline.
Bancroft adds, sex does not affect strength, endurance or the capacity of the body utilize oxygen.
In his research, he was monitoring the 12 athletes who used a treadmill 12 hours after intercourse. As a result, they do not indicate a decline in performance. In addition, also found no effect on grip, balance, lateral movement, reaction time or aerobic power. The same applies to effects on the mental concentration of male athletes.
Problems that may occur is the period of re-Factories or lethargy for 20 minutes for adolescents up to 24 hours for men middle age. But in this downturn faster athletes due to physical performance.
Bancroft discovered during orgasm, men's brains directly induced and relaxation that can last until the next day. The possibility of relaxing time this is not the best time to play in the final big game.
Some experts suspect that the hormone prolactin, which is at the peak a few hours after sex, may be influential. "But its role is not known for sure." Another possibility according to experts is the presence of psychological factors such as alertness and aggressiveness that affect performance.
