Beach tennis (BT) is a sport that has become popular in Brazil, and its unrestricted and unsupervised practice has often been associated with the occurrence of injuries. However, this belief is based on empirical knowledge, without any scientific basis. Therefore, the lack of evidence regarding the incidence of injuries in BT, as well as its relationship with training volume, can hinder decision-making regarding injury prevention strategies in this sport.

To analyze the incidence of injuries in BT practitioners and its association with training volume.

This is a cross-sectional study that included 120 individuals who practiced BT regularly and recreationally in the last six months, with a minimum frequency of once a week. Recreational practitioners were considered those who were non-competitors or who competed only in local competitions. The dependent variable of this study was the incidence of injuries, defined as the rate of injuries per 1,000 hours of BT practice. The independent variables included the weekly frequency and number of hours per day of training, in addition to pre-training warm-ups and practice of other sports. Participants were recruited through invitations via social media and direct contact with potential participants at sports clubs. Data collection was based on an online survey that contained data on personal information, occurrence of injuries, and characteristics of BT practice. Injury incidence was calculated using the following formula: (Number of injuries/Number of hours of exposure) x1000). The association between injury occurrence and variables related to training volume was analyzed using the Chi-square test. All analyses considered a 95% confidence interval and a significance level of 5%.

A total of 166 injuries were documented in 96 practitioners (80% of the sample), after 53,232 hours of play, which generated an injury incidence rate of 3.11 injuries per 1,000 hours of BT play. Bivariate analysis indicated that variables related to the volume of BT practice, such as weekly frequency (p = 0.83; effect size = 0.10) and daily hours of practice (p = 0.99; effect size = 0.10), warm-up before practice (p = 0.85; effect size = 0.10) and participation in other sports (p = 0.10; effect size = 0.15) are not associated with the occurrence of injuries in recreational BT practitioners.

The incidence of injuries in BT practitioners is relatively low and is not associated with training volume.

The results may contribute to the understanding of injuries in BT practitioners and indicate variables that do not need to be the focus of attention in injury prevention protocols in this population.
