This study was planned to to compare the hearing level of Kendo-Players with that of non-Kendo-Players to make clear whether or not long term practice of Kendo causes hearing loss. Pure-tone audiometry by air conduction was applied to 172 Kendo-Players and 76 non-Kendo-Players with an audiometer (Audiometer AA-69, Audiogram Recorder RE-05, Soundproof Room AT-45, Rion, Japan). Among them, the following cases were excluded from the analysis. 1) Cases who have had medication against tuberculosis. 2) Cases with perforation in the tympanic membranes. 3) Cases with occupational experience of more than a year in noise nuisance. 4) Cases with experience of head phone listening for more than one hour a day, twice a week for at least one year. The thresholds of hearing between 149 Kendo-Players (cases, age: 19-76) and 44 non Kendo-Players (controls' age: 20_78) were analysed to compare mean hearing thresholds between the age groups, and to examine covariance adjusted with age. The dose-response relationship was examined by the partial correlation coefficients controlled by age between the thresholds of hearing and the length of Kendo experience (year) or the total experience hours of Kendo (hour). The rusults showed that the hearing loss of Kendo-players was greater than non-Kendo players, especially at the frequency of 4000 and 8000 Hz in the age group of 30-59 years old. It is supposed that long term practice of Kendo may cause hearing loss. Further study, however, will be needed to re-examine the dose-response relactionship with more carefully selected samples for the epidemiological survey in the future.

This study was designed to clarify the stroke control in tennis. Fifteen subjects participated in this study. Nine of them were skilled tennis players and the others were unskilled subjects. They stroked at the targets which areas were 1, 4 and 9 m^2 in forehand strokes and volleys. Stroking accuracy performance and grip strength were used as indices of stroke control. Stroke accuracy was determined by balls which was put accurately at the target. Grip strength was determined by using the special grip tensiometer. The results obtained in this study were summarized as follows ; 1) The higher accuracy were observed in the skilled subjects than in the unskilled in all strokes, forehand strokes and volleys. 2) The grip strength applied to the tennis racket grip was recorded in forehand and backhand volleys. For the skilled, grip strength was continued on increasing for a while after the moment of ball impact. The unskilled subjects, however, were showedd that grip strength was decreased immediately after the ball impact.
