The intensity and energy expenditure of exertions, restitution speed, and rate of perceived exertion after tournament matches in Polish futsal players

Abstract

Purpose. Futsal is a very dynamic indoor team sport. Like in soccer, futsal players perform a number of efforts of different intensity during a match. In each match there are a few return substitutions to allow players to have some rest. The aim of the study was to assess the intensity and energy expenditure of single efforts and the dynamics of restitution after the efforts during successive futsal matches. Methods. The study consisted in measuring the players' (n = 11) heart rate (Hr) during four matches: A, B, c, D. The Hr measurement started during a pre-match warm-up and ended 5 min after the match. Results. The highest intensity of single efforts was noticed in match A. It equalled 90.22 ± 4.90% Hr max and it was the highest in comparison with other matches (p < 0.05). The energy expenditure of efforts performed by players in the matches was 395.11 ± 118.70 kcal. The mean energy expenditure of a single effort was 16.33 ± 5.36 kcal/min. The highest energy expenditure was registered in match A, and it equalled 17.31 ± 4.71 kcal/min during a single effort on the pitch after a return substitution. Conclusions. The intensity was very high, much higher than that of players' efforts in 11-a-side soccer. It should be concluded that an appropriate reduction in the time players spend on the pitch during their successive efforts in one match and the consecutive tournament matches can result in reducing the decrease in the effort intensity.

Characteristics of anteroposterior curvatures of the spine in soccer and futsal players

“…Similar exercise intensities, i.e. 85-90% Hrmax, in four consecutive soccer matches were noted by Wolań-ski et al [4]. cometti [12] claims that in soccer, explosive exercises constitute only 5%, whereas low-and medium-intensity ones amount to 60% of the total playing time.…”

“…The general model of the players' morphological characteristics varies depending on their pitch position, which is related to the performance of different activities [3,4].…”

Relationships among Physical Fitness, External Loads, and Heart Rate Recovery: A Study on Futsal Players during an Overseas Congested-Weeks Training Camp

“…This may lead to the increased likelihood of residual fatigue, risk of injury, significant strength deficits, and reduced physical performance due to decreased time for proper physical recovery ( Page et al, 2023 ). It was found that futsal athletes experienced a decrease in the intensity of their efforts, as measured by %HR max , towards the end of a tournament where they played four games over two days ( Wolański et al, 2017 ). The studies mentioned above suggest that fatigue resulting from previous matches significantly impacts players' performance, especially during congested schedules.…”

The effect of different tournament stages on the movement dynamics of futsal players while in ball possession

“…Futsal is a fast-paced, small sided football game characterized by the speed of movement, high intensity, and great spatial awareness of the players [1,2]. in futsal, players have less time and space to play when compared with association football (soccer).…”
