This method made the measurement of TL independent of equipment. sRPE has been shown to be a valid and reliable measure of TL 19 and has a good correlation with TRIMP in elite cyclists during different stages races. 20 sRPE is minimally influenced by the time of

by the duration of the exercise session in minutes, the session RPE (sRPE). Banister et al 8 introduced the concept of TRIMP as a marker of TL based on the intensity of the exercise, calculated as the product of the average heart rate (HR) reserve and the duration of exercise. There are different

noncontact injuries, both external load (ie, global positioning system) 15 and internal load (ie, session rating of perceived exertion [sRPE]) 13 variables have been used. However, according to the UEFA Elite Club Injury Study, 16 internal load markers have greater relevance as a risk factor than the

To identify contributing factors to the incidence of illness for professional team-sport athletes, using training load (TL), self-reported illness, and well-being data.


Thirty-two professional rugby league players (26.0 ± 4.8 y, 99.1 ± 9.6 kg, 1.84 ± 0.06 m) were recruited from the same club. Players participated in prescribed training and responded to a series of questionnaires to determine the presence of self-reported illness and markers of well-being. Internal TL was determined using the session rating of perceived exertion. These data were collected over 29 wk, across the preparatory and competition macrocycles.


The predictive models developed recognized increases in internal TL (strain values of >2282 AU, weekly TL >2786 AU, and monotony >0.78 AU) to best predict when athletes are at increased risk of self-reported illness. In addition, a reduction in overall well-being (<7.25 AU) in the presence of increased internal TL, as previously stated, was highlighted as a contributor to self-reported-illness occurrence.


These results indicate that self-report data can be successfully used to provide a novel understanding of the interactions between competition-associated stressors experienced by professional team-sport athletes and their susceptibility to illness. This may help coaching staff more effectively monitor players during the season and potentially implement preventive measures to reduce the likelihood of illnesses occurring.

measures challenging for assessing internal training load (TL). Subjective measures of exercise intensity, such as the rating of perceived exertion (RPE) 4 and session RPE (sRPE), 5 have become widely used to quantify internal TL, as they can be easily administered and interpreted. The TL is calculated

to quantify internal TL using a modification of the rating of perceived exertion (RPE) method developed by Borg. 6 This method is known as the session RPE (sRPE). The sRPE is derived by multiplying the overall RPE obtained at the end of a training session, using the Borg category-ratio 10 scale

. Consequently, the session rating of perceived exertion (sRPE), an athlete’s subjective RPE multiplied by session duration (in minutes), has been established as a simple and valid measure of ITL. 7 Based on the formative research of Foster et al, 8 sRPE is typically reported 30 minutes following session

Ratings of perceived exertion (RPE) have been proposed as a simple, noninvasive method to assess exercise intensity. 1 When multiplied by exercise duration, RPE can be used to assess internal training load (TL), this being named session-RPE (sRPE). 2 Traditionally, sRPE has been obtained by using
