Monitoring training volume through maximal number of repetitions or velocity-based approach

Purpose: This study aimed: i) to analyze the inter-individual variability in the maximal 5 number of repetitions (MNR) performed against a given relative load (%1RM) and, ii) to 6 examine the relationship between the velocity loss (VL) magnitude and the percentage of 7 completed repetitions with reg...

Relative loads 12 were determined from the individual load-velocity relationship. 13 Results: Individual relationships between load and velocity displayed coefficients of determination (R2 14 ) ranging from 0.986 to 0.998. The MNR showed an inter-individual 15 coefficient of variation (CV) ranging from 8.6 to 33.1%, increasing as %1RM increased. The relationship between %Rep and magnitude of VL showed a general R2 16 of 0.92-0.94 between 50 and 80% 1RM, which decreased to 0.80 for 90% 1RM. Mean individual R2 17 18 values were between 0.97 and 0.99 for all loading conditions. The %Rep when a given 19 percentage of VL was reached showed inter-individual CV values ranging from 5 to 20%, 20 decreasing as %Rep increased in each load condition. 21 Conclusions: Setting a number of repetitions had acceptable inter-individual variability, 22 with moderate relative loads being adjusted based on individual load-velocity 23 relationship.
