Physiological Responses During the Time Limit at 100% of the Peak Velocity in the Carminatti’s Test in Futsal Players

Abstract

The aim of this study was to investigate the physiological responses during the time limit at the intensity of the peak velocity of the Carminatti’s test (T-CAR). Ten professional futsal players (age, 27.4 ± 5.8 years, body mass, 78.8 ± 8.5 kg, body height, 175.8 ± 6.8 cm, body fat mass, 14.1 ± 2.6%) took part in the study. The players performed three tests, with an interval of at least 48 hours, as follows: the T-CAR to determine the peak velocity and the maximal heart rate; an incremental treadmill protocol to determine the maximal physiological responses; and a time limit running test at the peak velocity reached in the T-CAR. During the last two tests, a portable gas analyzer was used for direct measurement of cardiorespiratory variables. It was shown that the peak velocity was not significantly different from the maximal aerobic speed achieved in the laboratory (p = 0.213). All athletes reached their maximum oxygen uptake during the time limit test. The maximum oxygen uptake achieved during the time limit test was not different from that observed in the laboratory condition (51.1 ± 4.7 vs. 49.6 ± 4.7 ml·kg-1·min-1, respectively, p = 0.100). In addition, Bland and Altman plots evidenced acceptable agreement between them. On average, athletes took ~140 s to achieve maximum oxygen uptake and maintained it for ~180 s. Therefore, the peak velocity intensity can be used as an indicator of maximal aerobic power of futsal athletes and the time limit can be used as a reference for training prescription.

Cardiorespiratory fitness and muscular strength of deaf futsal players

“…The CPET with treadmill ramp protocol showed that VO 2max = 0.7±4.7 mL/kg/min for the hearing players. These values agree with those reported in Malaysian futsal players (Galy et al, 2015), VO 2max =51.4±3.2 mL/kg/min, and in Brazilian professional futsal players (Floriano et al, 2016), VO 2max =49.6±4.7 mL/kg/min. Our results, in addition to those found in the literature, provide a good benchmark for VO 2 in futsal players, although some studies (Alvarez et al, 2009; Beato et al, 2016) have reported VO 2max closed to 60 mL/kg/min.…”

Physical and Physiological Match-Play Demands and Player Characteristics in Futsal: A Systematic Review

“…In addition, as reported above, players achieve mean and peak VO 2 values during competition which correspond to their 76 and 99% of VO 2max , respectively. Upon review, 31 studies (Barbero-Alvarez et al, 2009 ; Gorostiaga et al, 2009 ; Baroni and Leal Junior, 2010 ; Castagna and Barbero-Alvarez, 2010 ; Milanez et al, 2011 ; Makaje et al, 2012 ; Boullosa et al, 2013 ; Oliveira et al, 2013 ; Pedro et al, 2013 ; Cuadrado-Peñafiel et al, 2014 ; Miloski et al, 2014 ; Soares-Caldeira et al, 2014 ; De Freitas et al, 2015 , 2019 ; Galy et al, 2015 ; Garcia-Tabar et al, 2015 ; Charlot et al, 2016 ; Floriano et al, 2016 ; Nakamura et al, 2016 , 2018 ; Naser and Ali, 2016 ; Barbieri et al, 2017 ; Barcelos et al, 2017 ; Valladares-Rodriguez et al, 2017 ; Nogueira et al, 2018 ; Zarebska et al, 2018 , 2019 ; Farhani et al, 2019 ; Nikolaidis et al, 2019 ; Teixeira et al, 2019 ; Wlodarczyk et al, 2019 , 2020 ; Bekris et al, 2020 ) have looked at the physiological characteristics of elite futsal players ( Table 2 ).…”

“…A detailed look at the published studies portrays that different kinds of tests have been used to assess aerobic performance in futsal (e.g., Yo-Yo IR1–IR2, FIET, 30-15 Intermittent Fitness Test, Futsal Circuit, and Carminatti's test) and that fitness field tests may be useful to evaluate the aerobic capacity on elite players (Castagna and Barbero-Alvarez, 2010 ; Boullosa et al, 2013 ; Garcia-Tabar et al, 2015 ; Floriano et al, 2016 ; Barbieri et al, 2017 ; Valladares-Rodriguez et al, 2017 ). For example, a study by Nakamura et al ( 2016 ) showed that Brazilian elite players covered 1,500 ± 287 m in the Yo-Yo IR1 test whereas a sample of under-20 players completed only 1,264.0 ± 397.9 m. Thus, it appears that such type of protocols may differentiate athletes from different age categories.…”

High-Intensity Intermittent Exercise Performed on the Sand Induces Higher Internal Load Demands in Soccer Players

“…The VO 2 and HR data were reduced to 15 s mean values. The highest values obtained in this 15 s interval for VO 2 and HR during the T-CAR protocol performed on the grass training surface were considered as VO 2 peak and HRpeak, respectively (Da Silva et al, 2015;Floriano et al, 2016). During the HIIE model on each training surface, the VO 2 and HR data were reduced to 5 s mean values, and the VO 2 and HR values obtained in each running set was considered as the average of the last two min of exercise (Floriano et al, 2016).…”
