INTRODUCTION: Even though floorball has become a popular team sport there are very little research on the physical demands that the floorball players requires. By characterizing the playing time, work intensity, and time for recovery during a game, the training could be optimized.
AIM: The aim of this study was to determine if heart rate monitoring and calculation of playing time could be used to characterize the players work intensity during a floorball game by measuring playing time, time for recovery and heart rate.
METHODS: One female floorball team (playing in the Swedish division 1) consisted by 14 players (17, 6 ± 0, 7 years, 167, 8 ± 6,4 cm, 60,4 ± 6,9 kg) participated in the study. During two games the player’s heart rate were measured by Polar team ² system and the games were recorded with a video camera (Go Pro Hero 3. To determine the player’s maximum heart rate, which was needed to calculate the intensity level, the player’s preformed a Yo-yo intermittent recovery test- level 1. Playing time during the games was analyzed by watching the videos and values for heart rate and work intensity were measured by Polar Team² software.
RESULTS: Total effective playing time was approximately 21 minutes, a substitution about 49 seconds and the time for recovery between substitutions about two minutes and twenty seconds. Time spent in intensity zone 91-100% of max was about twenty minutes and time spent in intensity zone 51-60% of max was about four minutes. Time spent in the intensity zones in-between (61-90% of max) was about 56 minutes.
CONCLUSIONS: Heart rate monitoring and calculation of playing time are, together with measuring for example movement patterns and distance, good tools for characterizing work intensity during a floor ball game, although level of intensity should be calculated as percentage of the heart reserve and it should be measured both for effective playing time and for the whole game.
Key words: match analysis, heart rate monitoring, intensity, playing time
