The effects of velocity-based versus percentage-based resistance training on athletic performances in sport-collegiate female basketball players

Abstract

Introduction: The study compared the effects of 6-week (2 sessions/week) velocity-based resistance training (VBRT) and percentage-based resistance training (PBRT) on athletic performance in Sport-College female basketball players.Methods: Fifteen participants were assigned to the VBRT (n = 8) or PBRT (n = 7) groups. The load in VBRT group were determined through the sessional target velocity and velocity loss monitoring, whereas PBRT group used a fixed-load based on percentage of 1-repetition maximum (1RM). Both groups completed intervention that involved the free weight back squat and bench press using the same relative load (linear periodization from 65% to 95% 1RM). Training loads data was continuously recorded. Measurements at baseline (T0) and post-training (T2) included 1RM, countermovement-jump (CMJ), squat-jump (SJ), eccentric-utilization-ratio (EUR), drop-jump height and reactive-strength-index (DJ, DJ-RSI), plyometric-push-up (PPU), 505 change-of-direction (COD), 10-m、20-m sprint (T-10、T-20), 17 × 15 m drill-lines (17-drill), Hexagon agility, and functional movement screen (FMS). A mid-term (T1) assessment was included to investigate the short-term effects of both methods and the fluctuation of personalized 1RM.Results: No between-group differences were observed at T0 for descriptive variables (p > 0.05). Both groups showed significant improvement in strength gains for back squat and bench press, but VBRT showed likely to very likely favorable improvements in CMJ, SJ, EUR, DJ-RSI, Hexagon and COD among athletic performance. The VBRT showed likely to very likely improvements in 17-drill and DJ, while PBRT showed unclear effects. The lifted weights adjusted by VBRT method were higher than prescribed by PBRT (p < 0.05) for the same subjects.Conclusion: Compared with fixed-load PBRT, VBRT enhanced power and athletic performance despite similar strength gains. VBRT can be regarded as a more functional resistance-training method under linear periodization.

Optimizing strength training protocols in young females: A comparative study of velocity-based and percentage-based training programs

“…On the other hand, contrary to the second hypothesis, the implemented exercise interventions induced similar muscle damage at each analyzed phase. Indeed, numerous studies compared the efficiency of VBT and PBT programs concerning various neuromuscular performances [ [22] , [23] , [24] , [25] , [26] , [27] , [28] ]. More precisely, available scientific evidence is partially consistent with the findings of the presented study.…”

“…For instance, a meta-analysis conducted by Liao et al [ 23 ] did not reveal statistically significant differences between VBT and PBT regarding effects on absolute strength, explosive strength, and speed. Moreover, no statistically significant differences in 1RM squat were observed between VBT and traditional strength training modality in the sport-collegiate female basketball players [ 25 ]. In addition, in line with the results obtained in this investigation, speed-based strength training elicited greater improvements in jump performances of female athletes, including CMJ and SJ tests relative to the PBT program.…”

Effect of individualised strength and plyometric training on the physical performance of basketball players

“…During the intervention, players were verbally instructed to perform each repetition at their maximum velocity for strength exercises (Weakley et al, 2020). In this way, both the intensity and the intra‐sets volume were monitored with a linear velocity transducer (Vitruve™, Madrid, Spain) (Pérez‐Castilla et al, 2019), since it has shown to be the most effective control method (Benavides‐Ubric et al, 2020; Dorrell et al, 2020; Sánchez‐Medina et al, 2017; Zhang et al, 2022). Regarding the intra‐set volume of the plyometric exercises, a low volume was sought (i.e.…”

Predictors of Speed and Agility in Youth Male Basketball Players

“…The DJ was performed from a 40 cm wooden box, as recommended by previous study [24]. The DJ protocol began with the athlete standing on the box with hands fixed on the hips for the entire protocol to eliminate the arm swing influence.…”
