    Context: Rhythmic gymnastics requires a high level of complexity and perfection of technical gestures, associated with well-developed physical and artistic capacities. The training-load and recovery profiles of rhythmic gymnasts across a season are unknown. Objective: To analyze the training load and recovery of professional rhythmic gymnasts during 1 season. Design: Cohort study. Setting: Brazilian National Training Center of Rhythmic Gymnastics and competition facilities. Patients or Other Participants: Eight gymnasts from the Brazilian national senior rhythmic gymnastics group. Main Outcome Measure(s): Session rating of perceived exertion (session-RPE) and total quality recovery (TQR) scores were collected daily for 43 weeks. We obtained the session-RPE after each session and TQR score before the first session of the day. Performances during 5 competitions were also recorded. The season was divided into 8 periods. Total weekly internal training load (wITL), training intensity, frequency, duration, recovery, and acute : chronic workload ratio were calculated for analysis. Results: The season mean wITL was 10 381 6 4894 arbitrary units, mean session-RPE score was 5.0 6 1.6, and mean TQR score was 12.8 6 1.3. The gymnasts trained an average of 8.7 6 2.9 sessions per week, with a mean duration of 219 6 36 minutes. Each competitive period showed increased wITL compared with the previous period. Trainingload variables (wITL and session-RPE) and recovery were inversely correlated. Gymnasts were poorly recovered (TQR , 13) during 50.9% of the season (n ¼ 167 times), especially during competitive weeks. Spikes in load (acute : chronic workload ratio 1.5) occurred across 18.1% of the season (n ¼ 55 times). Conclusions: The training-load variables and recovery changed throughout a professional rhythmic gymnastics group season, mainly during competitive periods. The correct distribution of training load is critical to ensure that gymnasts are entering competitions in a recovered state.
