Abstract: Heart rate and time-motion were examined in elite female handball players (U19) during six competitive matches.The average age of the participants was 17.9±0.3years, the average mass was 65.4±6.9kg, and the average height was 169.6±6.9 cm.Time-motion analyses of the players were performed using Video Manual Motion Tracker 1.0 software.The descriptive approach of the study determined the overall physical activity (distance [m]) and type of locomotion (standing, walking, jogging, medium-intensity running, high-intensity running, sprinting).The players' heart rates were monitored using TEAM Polar 2 Pro sport testers (Polar Electro, Kempele, Finland).The maximum heart rate was measured by means of the Yo-Yo intermittent level 1 (YYIRT1) recovery test.One-way ANOVA with repeated-measures was used to compare data on heart rate, covered distance and speed.Based on the results from the time-motion analysis, the average distance covered was 113.3±8.6 m per minute per match.The average distance the players covered during the matches was 3399±362.3m.The shortest distance (385.8±371.6 m), was traversed by standing and walking, and the longest distance (935.8±165.5 m) by jogging.The players' average heart rate was 183.7±7.3 beats•min -1 .The mean intensity during the matches represented 89.6±3.6% of the maximal heart rate (HR max ) .The results of this study demonstrate that handball is a high-intensity intermittent sport.The physiological profile shows that the players spent more than 83% of the playing time per match in the high-intensity zone (>85%HR max ).Based on this, training focused on anaerobic exercises and interval training methods is recommended.Anaerobic training ensures that players will be ready to carry out a high intensity performance and to maintain it during the whole match.Maintaining high intensity depends chiefly on the ability to replenish energy systems during the period spent in lower-intensity locomotion.We recommend working on the improvements in anaerobic and aerobic power during practice sessions.
