“…The use of the IMUs worn on the upper back is common across a range of sports (Chambers et al, 2015) and has been used to assess player load in racket sports (Dieu et al, 2014;Galé-Ansodi et al, 2016;Sasaki et al, 2018;Abdullahi et al, 2019;Wylde et al, 2019). However, in a study on Badminton, a low correlation was found between loading data obtained from an upper body-mounted IMU and differential ratings of perceived exertion (RPE) at the lower limbs (Wylde et al, 2019). This questions the validity of upper back worn IMUs for the measurement of playing intensity in Badminton.…”

“…The overall high work density observed in Badminton compared to field-based sports makes it difficult to observe clear differences in the Low and Medium Intensity zones. In a separate study, a low correlation was found between player load data obtained from an upper body-mounted IMU and differential ratings of perceived exertion (RPE) at the lower limbs (Wylde et al, 2019). Therefore, the consideration as to whether the upper body is the ideal location for IMU placement depends on a critical understanding of what information can be obtained from a specific sensor location.…”

This study investigated the relationships between internal and external training load metrics across a 2-week ‘in-season’ microcycle in squash. 134 on-court and 32 off-court ‘conditioning’ sessions were completed by fifteen elite squash players with an average (±SD) of 11 ± 3 per player. During every session, external load was captured using a tri-axial accelerometer to calculate Playerload; i.e., the instantaneous rate of change of acceleration across 3-dimensional planes. Internal load was measured using heart rate (HR), global (sRPE) and differential RPE (dRPE-Legs, dRPE-Breathing). Additionally, HR was used to calculate Banister’s, Edward’s and TEAM TRIMPs. Across 166 training sessions, Playerload was moderately correlated with TRIMP-Banister (r = 0.43 [95% CI: 0.29-0.55], p < 0.001) and TRIMP-Edwards (r = 0.50 [0.37-0.61], p < 0.001). Association of Playerload with TRIMP-TEAM (r = 0.24 [0.09-0.38], p = 0.001) was small. There was a moderate correlation between sRPE and Playerload (r = 0.46 [0.33-0.57], p < 0.001). Association of sRPE was large with TRIMP-Banister (r = 0.68 [0.59-0.76], p = 0.001), very large with TRIMP-Edwards (r = 0.79 [0.72-0.84], p < 0.001) and moderate with TRIMP-TEAM (r = 0.44 [0.31-0.56], p < 0.001). Both dRPE-Legs (r = 0.95 [0.93-0.96], p < 0.001) and dRPE-Breathing (r = 0.92 [0.89-0.94], p < 0.001) demonstrated nearly perfect correlations with sRPE and with each other (r = 0.91 [0.88-0.93], p < 0.001). Collection of both internal and external training load data is recommended to fully appreciate the physical demands of squash training. During a training microcycle containing a variety of training sessions, interpreting internal or external metrics in isolation may underestimate or overestimate the training stress a player is experiencing.
