Changes in power output under the influence of sprint training in handball players

Vol. 6, nr 1

31-40

The purpose of this paper was to study the power output using the Wingate test applied in an eight-week training programme realized by handball players, aided by repeated maximal-intensity exercise on a cycle ergometer. The study was conducted on 13 handball players divided into two groups. Group GS (n = 5) done the training in a gym and an additional sprint training on a cycle ergometer, wile group GG (n = 8) performed only the training in a gym. Both training programmes lasted 8 weeks, 5 times a week (Monday to Friday). On Saturday preceding the stan of the experiment and Saturday at the end of each week during the 8-week training programmes, the participants of the experiment came through the Wingate test on a cycle ergometer. The sprint training on the cycle ergometer caused a significant improvement in alactic anaerobic output (the power increase and maintenance phase - IMP) in the Wingate test (8.3% PalMp) and in lactic anaerobic out-put (the power decrease phase - DP) (13.3% PaDP) in group GS. No significant changes in these values were faund in these participants of the Wingate test who belonged to the group GG. The changes in the parameters measured in both groups examined varied significantly.

The purpose of this research was to study the effect of high-intensity training programme carried out with a cycle ergometer and in the form of run intervals on physical fitness as measured in a running test and on power output measured in Wingate test. The study was carried out on 24 subjects divided into two groups: group GC (12 persons) did the high-intensity training on a cycle ergometer; group GR (12 persons) did the training in the form of running. The training lasted 8 weeks, 5 times a week in both groups. Running test consisted of a series of four 50 m sprints (25 m + 25 m back) at 15-second intervals. The training improved alactic anaerobic output (the phase of power increase and maintenance phase (IMP) in the Wingate test) by 20.3%- VV[IMP] and 9.1%P[AlMP] in the GC group and by 15.2% W[IMP] and 11.5% P[aIMP] in the GR group, and lactic anaerobic output (the phase of power decrease (DP)) by 9.1% W[DP] and 12.4% P[aDP] for group GC and by 12.8% W[DP] and 10.8% P[[aDP] for group GR. In both groups, a significant improvement in time required to cover the distance in the series of four runs was noted (significantly larger in the group GR than in the group GC). The changes in running times, in terms of percentages, differed significantly between the groups. However, the groups did not differ in terms of their Wingate test results.
