RATING OF PERCEIVED EXERTION IN PROFESSIONAL VOLLEYBALL: A SYSTEMATIC REVIEW

Аннотация

The rating of perceived exertion (RPE) is a non-invasive, cost effective, and time efficient strategy to measure training loads. However, data can be collected without following specific procedures and across a range of methods (e.g., different RPE scales and/or different operational questions). Consequently, practitioners working in professional volleyball can use this information in various ways with different assessment standards between them. Therefore, the purpose of the current review was to systematically and critically evaluate the use of RPE- based methods in professional volleyball athletes. Electronic searches were conducted in four The main findings indicate that, to minimize the effect of the last exercise of the session, the athlete should be presented with the RPE question 10 to 30 minutes after the session is finished . Key words workload, team sports, athletes, monitoring Fatigue is a normal and desired part of the training process, and its severity can be observed as a continuum (Halson and Jeukendrup, 2004). When the proper balance between training stress and recovery is ensured, athletes experience acute fatigue in response to training sessions and recover within hours or days (Radojewski et al., 2018). However, if intense training continues without an adequate recovery period, athletes may enter a state of overreaching (Halson and Jeukendrup, 2004). When athletes experience a temporary reduction in https://scientific-jl.com/luch/ 2 5 3 Часть-43_ Том-1_ Май-2025 performance levels as a result of training, they enter a state of functional overreaching (Meeusen et al., 2013). If training continues and unplanned fatigue persists, athletes may experience non-functional overreaching that can last for several weeks. The last phase of the fatigue continuum is called overtraining syndrome, which is characterized by decreases in performance levels that are usually accompanied by psychological disturbances that can remain for long periods (Meeusen et al., 2013). To prevent these maladaptations associated with excessive training loads, it is recommended that practitioners monitor training loads to ensure adequate recovery. In addition to these negative performance implications, excessive training loads increase the risk of injury and illness in highperformance athletes (Gabbett, 2010). These heightened risks demonstrate the importance of monitoring how athletes respond to training and competition, showing that the key for a good exercise prescription is an adequate understanding of the effect promoted by training loads on the human body (Busso, 2003). Monitoring athletes’ training loads is better understood through sub-dividing loads into two types: internal and external (Halson, 2014). The internal training load (ITL) refers to the physiological stress that a training session induces in the athlete (Impellizzeri et al., 2005). The rating of perceived exertion (RPE) has become the most common method of monitoring the ITL as it is a non-invasive, cost effective, and time efficient strategy to measure training loads (Halson, 2014). The RPE method was originally developed by Borg (Borg, 1970), and Foster et al. (1995) created a simple technique to quantify the ITL using a modification of this scale. This technique is known as the session RPE (sRPE) and is derived by multiplying the overall RPE obtained at the end of a training session (or a match), using the Borg Category-Ratio 10 scale (BORG-CR10) by the total duration (in minutes) of the training session, to provide a modified training impulse (TRIMP) score. Developing an understanding of the ITL response to specific mesocycles and the transition between mesocycles could inform future training prescription. However, https://scientific-jl.com/luch/ 2 5 4 Часть-43_ Том-1_ Май-2025 RPE data can be collected without following specific procedures and across a range of methods (e.g., different RPE scales and/or different questions). For instance, in order to prevent that sRPE scores are overly influenced by how athletes felt at the end of the training session, the question should not be presented immediately after the session is finished (Foster et al., 1995). Consequently, practitioners working in professional volleyball can use this information in various ways with different scales and questions to assess this information. Therefore, a review of the literature specifically examining the available evidence and present suggestions to effectively monitor athletes with the RPE in professional volleyball would be of interest. Such a review can ensure that coaches would use quality information to prescribe training in applied settings. Thus, the purpose of the current review was to systematically and critically evaluate the use of RPE-based methods in professional volleyball.
