Four-week whole-body vibration training and its effects on strength, power and sprint performance in young basketball players - a randomized control trial

Abstract

We aimed to investigate whether the addition of whole-body vibration (WBV) to resistance training (RT) will be more beneficial in improving lower limbs muscle strength, power and sprinting performance than RT alone in young basketball players. We recruited 30 young basketball players to participate in four weeks of training and assessments. They were randomized into the WBV resistance training group (VRTG, n=15) and a conventional resistance training group (RTG, n=15), performed 3 times per week. At the beginning and end of the four weeks a back squat one-repetition maximum (1RMBS), Countermovement jump (CMJ), Squat jump (SJ), 10 meters (10m) and 20 meters sprint (20m) were performed. We found that: a) VRTG when added to RT can induce greater improvements in 1RMBS (percentage difference [PD], 8.4%, p < 0.001), CMJ (PD = 4.7%, p = 0.001) and SJ (PD = 1.6, p = 0.02) than RT alone. In contrary, significant time*group interactions were found for sprint times at 10m (p=0.08, F=3.2) and 20m (p=0.17, F=1.93). An additional 4-week WBV resistance training program proved effective in improving lower limb power and strength in young basketball players. When performed on a vibration platform (with accurate and constant vibration stimulus parameters), the resistance exercises were superior to their conventional forms and resulted in additional gains on measures of muscle power and strength, while sprint performance remained unchanged.

Comparing autoregulatory progressive resistance exercise and velocity-based resistance training on jump performance in college badminton athletes

“…The three most popular methods for assessing vertical jump are the CMJ, SJ, and DJ ( Kozinc, Plesa & Sarabon, 2021 ), and it is well-known that participants can achieve higher jump heights and greater output power in the CMJ compared with the SJ ( Bobbert et al, 1996 ). A study suggested that 4 weeks of PBT did not significantly improve the CMJ and SJ of athletes ( Kovacevic et al, 2022 ). However, the results of the present study were different; after 4 weeks of training, the participants’ CMJ in the APRE group was significantly improved.…”
