Background: Tennis is considered one of the most popular sports worldwide. The games in this sport have no predetermined time and can be played for hours, which requires excellence of
the competitive athlete in their movements for successful performance. The demands imposed both in training and in games with high load repetitions and failures in the kinetic chain or technique used
can influence the occurrence of injuries. Among the movements involved in the sport, the service is characterized by a movement above the head that requires high-speed performance. Groundstrokes
require greater amount of repetitions and may predispose to overuse injuries. In addition, rapid movements and sudden changes of direction on the court may contribute to traumatic injuries. The
occurrence of injuries can compromise performance and generate removal from sport in different degrees. Therefore, the aim of this study was to determine the frequency of injuries in tennis players,
the body regions and structures compromised by such injuries and the severity of the injuries.
Methods: Seventeen male athletes, average age of 24 years (± 3.7), competing at challenger level, were interviewed. The specific forms used contained questions on demographic data,
injuries during the career path, severity of the injuries, concerning the time loss from sports practice (7 days = mild; 8-28 days = moderate; above 29 days = severe), symptomatic site, the affected
Results: The athletes reported a total of 55 lesions, and the lower limbs were the most affected (49%), followed by upper limbs (36%), trunk (13%) and cervical spine (2%). By
analyzing more specifically the affected structures, muscle injuries in the lower limbs were the most common (14.5%) and the most common joint injuries were wrist and ankle (both representing 11% of
total). Fifty-eight percent of the injuries reported by these athletes were severe. Among these injuries, the greatest number was composed of the wrist joint injuries (31%), followed by the ankle
joint injuries (17%). Despite the injuries in the knee joint were not the most frequent, they were severe in 100% of cases. Minor injuries were mostly shoulder injuries followed by muscle injuries in
the lower limbs. The service was the most affected movement by injuries (29%), being that the injuries in shoulder and lumbar spine were the main responsible. The second most affected sportive
movement was the forehand (15%), followed by the movements associated with running or displacements in court (10%).
Conclusions: Most injuries caused severe removal from sports practice, which reinforces the need for further work focused on the description of the mechanisms and prevention of
injuries in this sport. Muscle injuries in the lower limbs were the most frequent and led to a removal for a shorter period of time. The most common joint injuries were in the wrist and ankle. The
service is usually the most affected movement and should receive special attention during rehabilitation and return of the athletes to the sport, especially in the presence of shoulder injuries and
low back pain.
