Background: Aerobic component is essential for providing energy to individuals performing efforts over an extended period of time. The combinations of aerobic and anaerobic component
determine a higher probability of success in sports or win competitions in the fighting line. The maximum oxygen uptake (VO2max) is widely used for assessment of cardiopulmonary function and maximum
functional reserve and subsequent screening of long term methods athletes. Thus, it is important to have an evaluation of the functional ability of the athlete that most closely matches the motor
gesture, leading to a better fit training. The practice of rafting, sport descent of rivers in inflatable boats, where members of the vessel paddle under the command of an instructor responsible for
guiding the group, is a high-intensity effort activity, but also featured long term. Despite the extensive literature on the physiological characteristics of athletes of different modalities, little
is known about the performance prediction parameters in Rafting athletes. Therefore, this study aimed to present an evaluation of proposed protocol VO2max and other ventilatory variables, adapted
rowing exercise that meets the peculiarities of rafting athletes
Methods: Participants were seven male athletes with 20.7 ± 3.7 years of age on the world four-times champion team Rafting. It was performed cardiopulmonary exercise test with rowing
ergometer (Concept II - VT, USA) following a protocol adapted with gas analyzer MedGraphics (VO2000 ™). The protocol consists of an initial load of 30 watts and 10 watts increments every 2 minutes.
The adequacy of the ergometer was made as angulation of the lower limbs and positioning of the athletes in the boat (right or left), where the ergometer drive belt was attached to the proximal half of
cable from an aluminum paddle to give real mechanical conditions of movement. We used descriptive statistics show the results
Results: There was the average of the following variables: body weight 72.6 ± 6.3 kg, height 176.6 ± 7.7 cm, maximum ventilatory volume (VEmax) 96.4 ± 2.5 l/min, maximum consumption
oxygen uptake (VO2max) 65.4 ± 2.4 ml/kg/min, maximum carbon dioxide production (VCO2max) 78.8 ± 2.74 ml/kg/min and respiratory quotient fatigue (QR) 1.2.
Conclusions: We conclude that the adjustments made in the mechanics of movement and used loads meet the specific mode, thus enabling the determination of a cardiorespiratory profile
