Predictive Validity of the Snatch Pull Force-Velocity Profile to Determine the Snatch One Repetition-Maximum in Male and Female Elite Weightlifters

Abstract

Background: The prediction of one repetition-maximum (1RM) performance from specific tests is highly relevant for the monitoring of training in weightlifting. Therefore, this study aimed at examining the predictive validity of the theoretical 1RM snatch (snatchth) computed from the two-point snatch pull force-velocity relationship (FvR2) to determine actual snatch 1RM performance in elite weightlifters. Methods: Eight (three female, five male) elite weightlifters carried out a 1RM snatch test followed by a snatch pull test with loads of 80% and 110% of the previously determined 1RM snatch. Barbell kinematics were determined for all lifts using video-tracking. From the snatch pull barbell kinematics, the snatch pull FvR2 was modeled and the snatchth was calculated. Results: The main findings indicated a non-significant (p = 0.706) and trivial (d = 0.01) mean difference between the actual 1RM snatch performance and the snatchth. Both measures showed an extremely large correlation (r = 0.99). The prediction accuracy of the actual 1RM snatch from snatchth was 0.2 ± 1.5 kg (systematic bias ± standard deviation of differences). Conclusions: This study provides a new approach to estimate 1RM snatch performance in elite weightlifters using the snatch pull FvR2. The results demonstrate that the snatchth-model accurately predicts 1RM snatch performance.

Long-Term Monitoring of Training Load, Force-Velocity Profile, and Performance in Elite Weightlifters: A Case Series With Two Male Olympic Athletes

“…Barbell FvR Profile and Snatch Performance. The 2-point approach was used to assess changes of barbell FvR parameters and to compute snatch th using the snatch pull exercise (28,29). For this purpose, a weekly snatch pull test with loads of 70 and 110% of the highest planned snatch pull load (i.e., weekly snatch pull 1RM) was always conducted on Monday evening as part of the regular training session (Table 1).…”

“…Likewise, FvR parameters (i.e., v 0 , F 0 , P max ) derived from maximal sprints (14,16), VJs (15,35), squat, and bench press exercises (23) have been found to be indicative and "sensitive" to change in relation to the external training load. For weightlifting, a reliable and valid snatch pull test has recently been introduced to measure barbell FvR parameters and to predict weightlifting (snatch) performance from barbell FvR profiles (28,29). To the authors' knowledge, there is no information available in the literature on the long-term monitoring of barbell FvR parameters and how-if at all-they moderate snatch performance (snatch th ) in elite weightlifting.…”

“…To the authors' knowledge, there is no information available in the literature on the long-term monitoring of barbell FvR parameters and how—if at all—they moderate snatch performance ( snatch th ) in elite weightlifting. Because snatch th is a function of the barbell FvR profile (28), associations between external training load and changes in barbell FvR parameters can provide valuable information for the goal to achieve peak performance at weightlifting competitions.…”

“…In the studies focusing on individual sports [ 23 , 24 , 25 , 26 , 27 ], Leo et al [ 23 ] investigated the effects of COVID-19 restrictions on training and performance physiology measures in U23 elite cyclists, concluding that COVID-19 restrictions did not negatively affect training characteristics and physiological performance measures for a period of <30 days. Boullosa and colleagues [ 24 ] monitored the associations between HRV, training load, and performance in a middle-aged recreational female runner during a competitive 20-week macrocycle divided into a first and second mesocycle, in which her best performances over 10 km and 21 km were recorded.…”

“…Sandau et al [ 25 ] examined the predictive validity of a new approach to the estimate one-repetition maximum (1RM) snatch computed from the two-point snatch pull force–velocity relationship, to determine the actual 1RM snatch performance in elite weightlifters. Aidar and colleagues [ 26 ] found that the maximum isometric force, rate of force development, time, velocity, and dynamic time had lower values, especially in the initial and intermediate phases in the sticking region, in Paralympic powerlifting athletes.…”
