Background:The anaerobic threshold (AT) is an aerobic fitness variable that has been used in the prescription of exercise intensities for training and improvement of the physical
skills of the athlete in several research protocols are used for determining the same, some using protocols assess ventilatory variables, and other metabolic variables in order to look with trust that
threshold (GIM e CHOI, 2016). Thus, evaluation of the functional abilities of an athlete becomes important in order to promote adjustments to the point of causing improvements in the athlete's
performance. Muay Thai is considered a martial art that requires complex skills and tactical excellence for success (MAYERS e BALMER, 2012). There are several studies related to athletic performance
in the case of physiological characteristics that each sport has, however still needs to be more studies about Muay Thai and its performance prediction parameters. Objective. Thus, the present study
was to evaluate the profile of the anaerobic threshold Muay Thai practitioners from the city of Votuporanga in São Paulo.
Method. The study included 7 males and mean age 30 ± 3,7 The staff was assessed during the preparation period, where they underwent a spirometry test using a treadmill (model treadmill) with
MedGraphics gas analyzer (VO2000 ™), using the Bruce protocol. The AT was determined by visual inspection method of ventilation curve. Results:There was the average of the following
variables: body weight 84.3 ± 9.6 kg, height 172.5 ± 3.3 cm, maximum oxygen consumption (VO2max) 39.7 ± 10.3 ml / kg / min oxygen consumption at anaerobic threshold (VO2LA) 24.3 ± 7.3 ml / kg / min,
which showed that the participants reached the anaerobic threshold to 67.3% considering their maximum values obtained during progressive exercise test. Conclusions: It is concluded
that the anaerobic threshold of Muay Thai practitioners evaluated in the study corresponds to 67.3% of VO2max, being an important intensity control parameter in physical training. However points out
the need of the use of cardiorespiratory evaluation protocols that can better meet the specificity of sport.
