The influence of strength output during recovery on the intermittent running and throwing power of ball game players

Abstract

  The purpose of this study was to examine the effects of strength output during recovery on intermittent exercise performance, and to evaluate the relationship between physical ability and intermittent exercise performance, including strength output. Test I consisted of a 20-m shuttle sprint followed by throwing a 4-kg medicine ball backwards during the 30-s recovery period; this was repeated 8 times. For test II, participants carried a 30-kg training bag a distance of 5 meters during each test I recovery period. Nineteen male university handball players performed test I and test II. Our results revealed the following:
1.  Test II resulted in greater decreases in both anaerobic running power and anaerobic throwing power than test I.
2.  There was a positive correlation between relative aerobic power and the retention rate of anaerobic running power during the 4th, 5th and 8th sets of test II.
3.  There was a positive correlation between the strength index and retention rate of anaerobic throwing power during the 8th set of test II, and a positive correlation between body weight and the retention rate of anaerobic throwing power during the 6th and 7th sets of test II.
These results indicate that with strength output during recovery, a high relative aerobic power is necessary to maintain intermittent anaerobic running power, and that muscle strength is important for maintaining intermittent anaerobic throwing power.
