Introduction: Biomechanical load in handball is high due to many multidirectional changes. However, training monitoring in general is mostly focused on physiological load and not on the biomechanical load. That is why it was proposed to differentiate session Rating of Perceived Exertion (sRPE) in a respiratory (sRPEres) and muscular (sRPEmus) load. However, current practices with differentiated sRPE in team handball for all exercise modes and different weekdays are unknown. Therefore, the aims of this study are to (1) describe and compare the distribution of sRPEres and sRPEmus of elite youth handball players with inclusion of all types of exercises during in-season microcycles, and (2) to explore the interrelationship between different training load indicators with sRPEres and sRPEmus as well. Methods: 13 female elite handball players (mean ± SD: age = 18.5 ± 1.2 years) were monitored during 12 weeks. After all training sessions sRPEres and sRPEmus were registered and multiplied by its duration into sRPEres-TL and sRPEmus-TL. Furthermore, training load indicators were collected during ball sessions using Local Position Measurement. Multilevel models were applied to account for within-players and between-players differences for sRPEres-TL and sRPEmus-TL, and Pearson correlations were calculated to determine the association between the load indicators and both sRPE-TL scores. Results: A total of 980 individual training sessions were collected. sRPEmus-TL was significantly higher compared to sRPEres-TL in all exercise modes, with largest differences for the ball session (p < .05). Furthermore, sRPEmus-TL of Tuesday’s, Wednesday’s and Thursday’s ball session was higher compared to sRPEres-TL, when compared to Monday’s ball session. Moderate-to-large correlations existed between the other training load indicators with both sRPE scores, whereas substantial differences between both sRPE scores existed. Conclusion: It can be concluded that in handball differences exist between sRPEres-TL and sRPEmus-TL in all exercise modes and are most apparent in ball sessions. Interrelationships between load indicators support the idea that sRPEres-TL and sRPEmus-TL are not the same and that physiological and biomechanical load need to be distinguished. In practice, differentiated sRPE can be used to better understand the biomechanical loads, players sustained, rather than mainly the physiological loads.
