The association between internal and external measures of training load in batsmen and medium-fast bowlers during net-based cricket training

Purpose: To examine the relationship between session rating of perceived exertion (sRPE) and measures of internal and external training load (TL) in cricket batsmen and medium-fast bowlers during net-based training sessions. Methods: The internal (heart rate), external (movement demands, PlayerLoad), and technical (cricket-specifc skills) loads of 30 male cricket players (age 21.2 ± 3.8 y, height 1.82 ± 0.07 m, body mass 79.0 ± 8.7 kg) were determined from net-based cricket-training sessions (n = 118). The relationships between sRPE and measures of TL were quantifed using Pearson product-moment correlations respective to playing position. Stepwise multiple-regression techniques provided key internal-and external-load determinants of sRPE in cricket players. Results: Signifcant correlations were evident (r =-.34 to.87, P <.05) between internal and external measures of TL and sRPE, with the strongest correlations (r ≥.62) for GPS-derived measures for both playing positions. In batsmen, stepwise multiple-regression analysis revealed that 67.8% of the adjusted variance in sRPE could be explained by PlayerLoad and high-intensity distance (y = 27.43 + 0.81 PlayerLoad + 0.29 high-intensity distance). For medium-fast bowlers, 76.3% of the adjusted variance could be explained by total distance and mean heart rate (y = 101.82 + total distance 0.05 + HRmean-0.48). Conclusion: These results suggest that sRPE is a valid method of reporting TL among cricket batsmen and medium-fast bowlers. Position-specifc responses are evident and should be considered when monitoring the TL of cricket players.
