[Longitudinal and specific analyses of physical performance in handball].

BACKGROUND

Sports-specific, biomechanical measuring stations and measuring-station trainings have become common practice in many forms of sports and are an essential element of the complex assessment of physical performance. In handball, however, there is still considerable research potential in this respect as well as in the systematic generation and acquisition of the requirements profile and progress of strain.

OBJECTIVE

The prime objective of the longitudinal study was to determine the potential performance and development of handball players (3 rd league) in general and in terms of handball sport in particular. Another objective was to establish correlations between tests and indicators of performance in competitions.

MATERIALS AND METHODS

13 handball players (age: 26.5 ± 3.6 years) were tested three times (before and after the pre-season preparation phase and at the end of the first half of the season) on two test days each. The examination was composed of sprint test (ST, day 1), handball-specific complex test (HBKT, day 1) and assessment of treadmill diagnostics (LD, day 2). The surveyed parameters were lactate and heart rate (LD/HBKT) as well as time (ST, HBKT) and the number of errors (HBKT).

RESULTS

The cardiac (Hfmax = 201 min-1) and metabolic strain (lactate = 17.8 mmol/L) in the HBKT were very high. In the preparatory phase, the average magnitudes of effect registered were at d = 0.31 (ST parameter), d = 0.68 (HBKT parameter) and d = 0.98 (LD parameter). The most significant improvements throughout the entire period of time were registered in the parameters v2 (LD; η2 = 0.371), total goal-throwing time (HBKT; η2 = 0.250), total penalty time (HBKT; η2 = 0.236) and total round 2 (HBKT; η2 = 0.227). In HBKT and LD, the performance level was stabilised by the end of the first half of the season. In terms of speed, however, there was a decline in performance abilities. The competition performance has its highest degree of correlation with cardial (defense: r = -0.656) and metabolic (offensive: r = -0.655) recuperativeness in HBKT.

CONCLUSIONS

The findings of this longitudinal survey are on the one hand intended to make assessments of physical performance more efficient (isolated sprint test no longer required) and to improve data output (HBKT: throwing velocity; reference database). In this context, a more extensive consideration of indicators for competition performance and their correlation to specific parameters is recommendable. On the other hand, the applied training contents must be further optimised in terms of their severity and chronology.
