Skin diseases were investigated in 1,088 male players of high school sport clubs. The controls were 117 members of non-sport (culture) clubs of the same high schools and 391 male patients of the same age groups seen in our out-patient clinic. Representative diseases of the sport player group were tylosis (72%), acne vulgaris (52%), tinea pedis (21%), friction blister (14%), traumatic scar and pigmentation (9%), and black heel (8%). Acne vulgaris, tylosis and tinea pedis were also present in each control group, although the incidences being low. Tylosis ranked first in each sport event (93 to 37%). It was observed that the highest incidence of tinea pedis in the volleyball players (29%), friction blister in the Japanese fencing “Kendo” group (24%), acne vulgaris in the kendo group (27%) and black heel in the basketball players (25%). The predilection pattern of tylosis was classified into the toe metatarso-phalangeal joint flexor-side>finger metacarpo-phalangeal joint flexor side type, to which the basketball, ping-pong, soccer and rugby players belonged, and the reverse type, to which the soft-ball tennis, volleyball and skiers belonged. The rate of bilateral occurrence of tylosis was significantly lower in the baseball, kendo, ping-pong and soft-ball tennis players. To assess the degree with which each disease hinders sports training, the concept of training hindering index was devised.
