The Role of Aerobic Fitness on Session Rating of Perceived Exertion in Futsal Players

PURPOSE: The aim of this study was to verify the influence of aerobic fitness (VO2max) on internal training loads, as measured by the session rating of perceived exertion (session-RPE) method. METHODS: Nine male professional outfield futsal players were monitored for 4 wk of the in-season period with regards to the weekly accumulated session-RPE, while participating in the same training sessions. Single-session-RPE was obtained from the product of a 10-point RPE scale and the duration of exercise. Maximal oxygen consumption was determined during an incremental treadmill test. RESULTS: The average training load throughout the 4 wk period varied between 2,876 and 5,035 arbitrary units. Technical-tactical sessions were the predominant source of loading. There was a significant correlation between VO2max (59.6 ± 2.5 mL · kg-1 · min-1) and overall training load accumulated over the total period (r = -0.75). CONCLUSIONS: The VO2max plays a key role in determining the magnitude of an individual's perceived exertion during futsal training sessions.
