“…From applied and clinical perspectives, the present study advances our understanding of the load‐hamstring injury relationship in professional football. The notion of physical load involves an understanding of the interplay between intensity, volume, and frequency to determine training outcome, yet this is underappreciated in the load‐injury literature. While technological advances now permit a detailed measurement of player external load, when compared with s‐RPE measures, quantification of external load via global positioning system (GPS) fails to represent the actual physiological stress imposed upon players .…”

“…Despite being widely adopted in this context, s‐RPE is not without limitation as a global measure of effort perception. It might underrepresent the stochastic demands of football and obfuscate the separate effects and contribution of intensity and duration on the training process …”

“…Training and match loads were quantified as session duration (minutes) and RPE. Players rated the global intensity of all sessions and matches using level‐anchored semi‐ratio CR‐10 Borg scale (Borg CR10 ® ) . Science and/or medicine staff collected RPE ~30 minutes after completion of the session/match.…”

Training and competition loads have emerged as modifiable composite risk factors of non‐contact injury. Hamstring strains are the most common injuries in football with substantial burden on the individual player and club. Nevertheless, robust evidence of a consistent load‐hamstring injury relationship in professional football is lacking. Using available data from the Qatar Stars League over three competitive seasons, this study investigated the separate and combined effects of perceived exertion and session duration on hamstring injury occurrence in a sample of 30 outfield football players. Load variables were calculated into 7‐day, 14‐day, 21‐day, 28‐day periods of data, and week‐to‐week changes for average ratings of perceived exertion (RPE; au) score and session‐RPE (s‐RPE; session‐duration × score), plus the cumulative training and match minutes and s‐RPE, respectively. Conditional logistic regression models estimated load‐injury relationships per 2‐within‐subject standard deviation increments in each candidate variable. Associations were declared practically important based on the location of the confidence interval in relation to thresholds of 0.90 and 1.11 defining small beneficial and harmful effects, respectively. The uncertainty for the corrected odds ratios show that typically high within‐subject increments in each candidate variable were not practically important for training‐ and match‐related hamstring injury (95% confidence intervals range: 0.85 to 1.16). We found limited exploratory evidence regarding the value of perceived exertion and session duration as etiological factors of hamstring injury in Middle‐East professional football. Monitoring remains valuable to inform player load management strategies, but our exploratory findings suggest its role for type‐specific injury risk determination appears empirically unsupported.

“…In the literature, most of articles are often looking for a correlation between the variables ETL and ITL. The most recent meta-analysis regarding this issue [4] is searching precisely for that. However, we are convinced that this way of thinking about TL leads to important errors.…”

“…The control of training load (TL) has become a very interesting field for investigation in sports [1] [2] [3]. The load administered (for example, as a training session) is considered the external training load (ETL) and the way in which each athlete responds to it is considered internal training load (ITL) [4], howev-Health er, few tools are used to assess ITL. Among them, the most used are the rating of perceived exertion of the training session (sRPE and its different variants) [5] or the algorithm called Training Impulse (TRIMP) [6].…”

The control of training load has become a very interesting field for investigation in sports, but few tools are used to assess internal training load (ITL). The aim of this study is to use a post-exercise analysis methodology in different athletes and situations to establish its utility and reliability as a measure of ITL. In a retrospective review, we analysed 112 measurements of 74 subjects (38 men and 36 women) grouped in: University students (UNI); national team (FUTSAL 1); university team (FUTSAL 2); athletes (ATL); badminton players (BADM). Measures of Heart Rate Variability (HRV) were made with a Polar V800 with a thoracic band H10, during 5 minutes in a seated position after exercise. We calculated the Root Mean Square of the successive differences between adjacent RR intervals (RMSSD) and its slope from exercise to recovery. Measurements from UNI, FUTSAL-2, ATL-M and ATL-F were grouped into three categories of intensity (60%, 75% and 100%). RMSSD-Slope values were lower as intensity increased but different for every subject. In the BADM and FUTSAL-1 groups, RMSSD-Slope was progressively lower after consecutive matches for every player. The RMSSD-Slope seems to be a very accurate method to assess ITL.
