Physiological Demands of an Intermittent Futsal-Oriented High-Intensity Test

Abstract

The aim of this study was to provide evidence for specific physiological demands of a futsal time-motion analysis devised progressive and intermittent shuttle-running test (futsal intermittent endurance test [FIET]). Eighteen full-time professional futsal players (age 20.6 +/- 3.1 years, body mass 71.6 +/- 8.5 kg, height 175 +/- 7.9 cm) volunteered to participate in this study. In a random order and on separate days, they performed the FIET and a treadmill test (TM) to assess aerobic fitness. Physiological demands were examined by monitoring exercise heart rates (HRs), O2, and blood-lactate concentration (BLac) during FIET and TM conditions. During the FIET, players covered 1,464 +/- 136 m attaining a mean speed at exhaustion of 16.5 +/- 0.6 km h. The mean FIET duration was of 13.24 +/- 1.13 minutes. Peak O2, HR, and BLac were 95 +/- 6.4, 99 +/- 2, and 108 +/- 25% of treadmill O2max, HRmax, and BLac, respectively. Large correlations were found between speed at ventilatory threshold and maximal speed at O2max with FIET performance (r = 0.60 and 0.61, p < 0.01, respectively). Peak O2 during the FIET was significantly lower than O2max. Although there was no mean difference between peak exercise HR in the TM and FIET conditions, significant intraindividual bias was evident. This study showed that FIET heavily stresses both the aerobic and anaerobic energy systems to a level that is similar to what was reported in futsal game play. Coaches may use the FIET to examine futsal players' ability to cope with intermittent high-intensity exercise. It is suggested that the highest HR found during the FIET should be regarded as peak HR and not as individual HRmax.

Effect of high-intensity interval training on body composition and bioenergetic indices in boys - futsal players

“…In a study on the effect of interval training at 95% and 100% of the velocity at VO2max on aerobic physiological indices and running performance, Denadai et al (2010) found that post-training VO2max did not change in two groups and that VO2max performance was significantly increased in the group of 100% of VO2max [26]. Also, castagna et al (2010) studied the physiological aspects of futsal-oriented HIIT and reported that aerobic velocity and threshold, maximum velocity, and VO2max were significantly related to training program [19]. Astorino et al (2012) examined the impact of HIIT on cardiovascular performance, VO2max, and muscular power and observed a significant improvement in VO2max as compared to baseline [27].…”

“…High-quality, low-volume trainings are, in essence, used to find a training program with the appropriate intensity, duration, and repetition which can result in rapid and concurrent improvement of aerobic and anaerobic power. Therefore, since few studies have been reported on the effect of HIIT training on the improvement of aerobic and anaerobic performance among futsal players [18,19] and yet they have yielded inconsistent results, and given the possible usefulness of HIIT training and the importance of bioenergetic indices in futsal, the present study was aimed at examining the effect of HIIT training on body composition and bioenergetic indices.…”

Características fisiológicas, avaliação e prescrição do treinamento aeróbio no Futsal

“…It may also be suggested that the performance in FIET requires the participation of the neuromuscular system, since the protocol involves racing with changes of direction at high intensity held in a short distance, indicating that it can also be influenced by peripheral fatigue, and the physiological mechanisms (temporary and / or accumulated fatigue) that contribute to the FIET interruption are similar to those that interrupt the test of repeated sprints 8 . Additionally, Castagna, and Barbero Álvarez 8 demonstrated that even with 47% of the test time being used for recovery periods, FIET can be considered a field protocol that emphasizes the use of the anaerobic pathway, showing that this metabolism plays an important role in the onset of fatigue.…”

“…Based on the aforementioned information, it could be concluded that FIET is a peculiar field test used to evaluate the performance of Futsal players, since it provides relevant information about the physiological characteristics necessary for performing high-intensity intermittent exercises according to the modality needs 8,9 .…”

“…Since it is a team sport characterized by intermittent efforts of high intensity, interspersed with variable recovery periods during matches, futsal under the physiological point of view, is a balanced modality, in which the level of performance of athletes depends on variables related to both aerobic and anaerobic metabolism [2][3][4]7,8 , and the effort: pause ratio during matches is approximately 1: 1 9 . By means of analysis of movement, studies has shown that deciding periods on a fustal match are preceded by rapid and high-intensity runs (10 -30 m or 2 -4 seconds), and professional players spend approximately 5 -12 % of the match time performing high-intensity races (> 15 km.h -1 ), highlighting the importance of high-intensity interval training for futsal players 1 .…”
