Sažetak

We examined whether lifting velocity can serve as an objective indicator for predicting clean and jerk one-repetition maximum (1RM). Fourteen competitive adolescent male weightlifters completed two sessions, each involving an incremental loading test at 50%, 70%, 80%, and 90% of 1RM, followed by load increases until reaching actual 1RM. Peak velocity (PV) was recorded for all lifts using a GymAware device. In second session, 1RM was predicted using the individual load–PV relationship derived from three exercise phases (clean, jerk, and entire movement) combined with either the actual or optimal minimal velocity threshold (MVT) from first session. Absolute errors from the test-retest of the actual 1RM (5.0 kg) were not significantly different to those from all velocity-based methods (range = 6.3‒10.2 kg; p=.158‒0.730), except for the larger errors obtained for the clean phase combined with the actual MVT (10.1 kg p=.008). Random errors for the actual 1RM (15.7 kg) fell within the range of velocity-based methods (13.2‒23.1 kg). These results suggest that, although a direct assessment of the actual 1RM remains the most accurate method, measuring PV during warm-up sets may serve as a supplementary tool for guiding the selection of initial attempts in weightlifting competitions.
