Background: With the wheelchair basketball becoming increasingly competitive, the highest level of performance has become required from athletes. In this way, proper monitoring of
training and game loads is fundamental to optimize athletic and technical performance in players, allowing the development of more specific and safe practice. Studies have shown different
technical/tactical and physiological behaviors among athletes of different functional classes, position on the court and practice time. The aim of this study was to describe the internal load (IL)
during a wheelchair basketball game and correlate the heart rate data to the functional classification
Methods: The group of study consisted of 10 athletes from the wheelchair basketball teams of the State University of Londrina and the State University of Maringa, with an average age
of 32,10 (±6,56). To obtain the heart rate values a friendly match game was performed, with four times of 12 minutes. The frequency data was measured using heart rate monitors Sunto Team Pod (SuntoOy,
Finland). The calculation of the internal load was made over time, in minutes, on each heart rate zone (- 50-60%, > 60-70%, > 70-80%, > 80-90%, > 90-100%), using the formula proposed by Edwards. Mann
Whitney tests and Spearman correlation tests were performed between the heart rate variables and functional classes, adopting p <0.05.
Results: Players of higher functional classes showed higher internal load values (155 ± 55.96) that the lower classes (128 ± 42.12); there were no significant differences between the
functional classes and HR at rest (p = 0.67), maximum HR (p = 0.405) and average HR (p = 0.133); there was moderate correlation (0.68) between HR at rest and functional classification and strong
correlation (0.85) between maximum HR and average HR.
Conclusions: Players of higher functional classes have a higher internal load compared the lower classes; There were no differences in maximum, average and at rest heart rate values
between functional classes; strong correlation between maximum HR and average was observed.
