AB [EN] Background. This study aimed (I) to assess the inter-rater agreement for measuringthe mean velocity (MV) of the barbell with the iLOAD R© app, and (II) to compare themagnitude of the MV and total work of a training session between the iLOAD R© appand a linear encoder (reference method).Method. Sixteen young healthy individuals (four women and 12 men) were tested intwo sessions separated by 48 h. The 10 repetition maximum (RM) load was determinedin the first testing session in the half squat exercise. The second testing session consistedof 3 sets of 10 repetitions during the half squat exercise performed against the 10RMload. Both the iLOAD R© app and a linear encoder were used to calculate the MVand total work of each training set. MV was recorded with the iLOAD R© app by twoindependent researchers to evaluate the inter-rater agreement.Results. Trivial differences and nearly perfect correlations were observed between ratersfor the MV values collected under individual sets (effect size [ES] ≤ 0.02, r ≥ 0.987), aswell as for the whole training session (ES = 0.01, r = 0.997). Trivial-small differencesand nearly perfect correlations were observed between the iLOAD R© app and the linearencoder (Chronojump, Barcelona, Spain) for MV (EV ≤ 0.25, r ≥ 0.903) and total work(ES ≤ 0.05, r ≥ 0.973). Bland-Altman plots did not reveal heteroscedasticity of theerrors between the iLOAD R© app and the linear encoder for MV (r2 = 0.010) and totalwork (r2 < 0.001).Conclusions. iLOAD R© is a valid smartphone app which can provide real-time feedbackof the MV and total work completed in a set of multiple repetitions in the half squatexercise.
