-Abstract-
The purpose of this study was to investigate the correletion regarding the isokinetic
muscular performance characteristics of the elbow, shoulder, low back, and knee joint of
softball pitchers.
The results were as follows
1. At the correlation between isokinetics flexion-extension of elbow joint and throwing
speed, elbow flexion was significantly correlated at 60deg/sec, 180deg/sec in domiant,
and elbow flexion 60deg/sec in nondominant. Dominant elbow flexion PT%BW was
significant correlation between 60deg/sec and throwing speed.
2. At the correlation between isokinetics flexion-extension of shoulder joint and
throwing speed, shoulder extension was significant correlation 60deg/sec, 120deg/sec in
dominant, and shoulder extension 60deg/sec in nondominant, dominant shoulder extension
PT%BW was significant correlation between 60deg/sec and throwing speed.
3. At the correlation between isokinetics flexion-extension of low back and throwing
speed, low back flexion was significant correlation 30deg/sec in dominant.
4. At the correlation between isokinetics flexion-extension of knee joint and throwing
speed, knee extension was significant correlation 60deg/sec in dominant, and knee flexion
PT%BW, knee extension PT%BW was 60deg/sec significant correlation between
throwing speed.
