Introduction: Heart rate (HR) is one of the easily available physiological indicators. Today, it is one of the most frequently used and exceptionally reliable load intensity analysis method, but it is also considered to be a reliable benchmark for the assessment of load intensity. Objective: The objective was to analyse the course of load intensity in the most exposed players during a second-league handball match in relation to the game positions. The heart rate of nine players (4 backs, 3 wings and 2 pivots) during individual matches was monitored using Polar Team². Results: The study results indicate statistically significant lower values in load intensity of players during the second half-time. The highest mean value of HRmax in all matches was determined in the backs: 83.0±6.1 % HRmax. These players also showed the highest decrease in load intensity (1st half-time 84.3±6.3 % HRmax; 2nd half-time 81.1±5.6 % HRmax). In terms of practical significance ("effect size"), the difference can be considered medium-significant (Cohen's d = 0.52). The backs are often in contact with the ball, and they are the most involved in both defence and offence. The wings are mostly in static positions, and they had the lowest mean values: 80.3±9.7 % HRmax. Conclusion: Based on the results, we recommend including suitable game exercises in training of the same age and performance category with a similar intensity. The differences in the load intensity of female players are namely caused by the different game positions, the game system and the related. [ABSTRACT FROM AUTHOR] |
