To investigate the effects of judo-and kendo-training on figer flexion strength (FFS), single FFS (S-FFS)in 2nd fingers (IIs),3rd fingers (IIIs),4th fingers (IVs),5th fingers (Vs), and combined FFS (C-FFS) in II IIIs, III IVs, IV Vs, II III IVs, III IV Vs, II III IV Vs were measured in 19 judo-athletes (average training period: 13 years),30 kendo-athletes (average training period: 13.5 years) and 50 non-athletic students as untrained controls. All the subjects were right-handed male. The isometric FFS were measured at the right angles of PIP joint (s) by the load cell method. The results were summarized as follows:
1) Both the kendo-and the judo-athletes had significant stronger FFS than the controls in all kinds of FFS.
2) The kendo-athletes had significant stronger FFS in their left Vs than in their right Vs, although their C-FFS in the left II III IV Vs was significantly weaker than that in the right II III IV Vs
3) The judo-athletes had significant stronger S-FFS in IIs and IIIs in both hands than the kendo-athletes. No significant difference, however, was found between any C-FFS in the judo-athletes and in the kendo-athletes.
4) There were significant correlations between the grades (dan-i) and S-FFS (IIs) in both hands in the judo-athletes, and the training periods or the grades and left S-FFS (IIs-Vs) in the kendo-athletes.
These results suggest distinctive effects of kendo-training on FFS in left hand, especially in left Vs, and those of judo-training on FFS in IIs in both hands.
