Abstract
Introduction: Futsal is an, high-intensity intermittent sport, with energy supplied by both aerobic and anaerobic pathways. This reality in futsal makes it important to assess and understand the physiological indicators such as lactate, heart rate, respiratory exchange ratio, and VO2max in futsal players. Futsal players must have high aerobic fitness, and evaluating aerobic fitness indicators and their evaluation methods requires understanding field tests related to this sport. On the other hand, strengthening various physical aspects of futsal players requires accurate and specific evaluation of the game of futsal, and accurate evaluation requires accurate and specific tools for this sport;. The aim of this study was to investigate the relationship between Bruce laboratory test (BLT) and Field Tests (YO-YOIRT2 & FIET) in determining aerobic power in elite futsal players.
Methodology: Fifteen elite futsal players (age: 20.4±1.85 yrs.; height: 1.78±4.37 m, body mass: 66.33±7.13 kg, and BMI: 20.80±1.62 kg/m2) participated in this study. After familiarization with the study procedure, the main tests were performed on three different sessions, interspersed with one week interval. Within these three sessions, the participants randomly performed the Bruce laboratory test on treadmill, the YO-YOIRT2 test, and the FIET test for collecting VO2max, RER, blood lactate, and Maximal Heart Rate (MHR) via BLT and FIET, gas analysis, Lactometer, and Heart rate monitoring (Polar system), respectively. Pearson correlation coefficient was used to relationship between the variables.
Results: Data analysis showed a significant positive correlation between the factors of VO2max (P=0.034, r=0.54), RER (P=0.017, r=0.60) in the Bruce and YO-YOIRT2 tests, and blood lactate (P=0.017, r=0.60) in the Bruce and FIET tests. Additionally, there is a significant positive correlation between the maximum heart rate factor tests Bruce and YO-YOIRT2 (p=0.001, r=0.82), Bruce and FIET (p = 0.001, r =0.95), and Yo-YoIRT2 and FIET (p=0.001, r=0.81). However, there was no significant correlation between the VO2max and RER factors in the Bruce and FIET tests, and between the VO2max and RER factors in the YO-YOIRT2 and FIET tests. Additionally, there was no significant correlation between blood lactate in the Bruce and YO-YOIRT2 tests, and between the YO-YOIRT2 and FIET tests.
Conclusion: Based on the results of this study, it can be stated that the YO-YOIRT2 test is a valid and reliable test for assessing the aerobic capacity of elite male futsal players. Moreover, according to the between blood lactate levels in the Bruce test and FIET, as well as the HRmax factor across all three laboratory tests (Bruce test) and field tests (Yo-Yo IRT2 and FIET) in elite male futsal players, it can be stated that the physiological stress imposed by these tests on different body systems is similar.
