Concurrent Validity and Reliability of the Load-Velocity Relationship to Predict the One-Repetition Maximum during Three Weightlifting Derivatives

The study investigated the concurrent validity and reliability of load-velocity relationship to predict one-repetition maximum (1RM) power clean from knee (PCK), high pull (HPK), mid-thigh (MTCP). For each exercise, 12 participants performed two 1RM sessions tests measure barbell’s at 30, 45, 60, 75, 90% 1RM. velocity recorded load was used establish linear regression equation and, consequently, value. A low between direct test predicted observed for PCK (typical error [TE]=3.96 4.50 kg, coefficient variation [CV]=4.68 5.27%, effect size [ES]=-0.76 -0.58, Bland-Altman bias [BAB]=9.83 11.19 kg), HPK (TE=4.58 5.82 CV=6.44 8.14%, ES=-0.40 -0.39, BAB=3.52 4.17 MTCP (TE=6.33 8.08 CV=4.78 6.16%, ES=-0.29 -0.19, BAB=3.98 6.17 kg). Adequate However, based on limits agreement, lower measurement errors were obtained in comparison all exercises. In conclusion, not able values with accuracy PCK, HPK, MTCP. Moreover, most reliable
