The Effects of Resistance Training on Explosive Strength Indicators in Adolescent Basketball Players

Abstract

The purpose of this study was to assess the effects of a lower- and upper-body 10-week in-season resistance training program on explosive strength development in young basketball players. Twenty-five adolescent male athletes, aged 14-15 years old, were randomly assigned to an experimental group (EG; n = 15) and a control group (CG; n = 10). The subjects were assessed at baseline and after training for squat jump (SJ), countermovement jump (CMJ), Abalakov test, drop jump, and seated medicine ball throw (MBT). The EG showed significant increases (p < 0.05) in all the variable scores. Conversely, the CG significantly decreased (p < 0.05) in SJ, CMJ, and Abalakov test scores and significantly increased in the results of MBT test (p < 0.05). The groups were similar on pretest, but significant differences (p < 0.05) occurred on posttest in all the variables. The results of this study show that a 10-week in-season resistance training program with moderate volume and intensity loads increased vertical jump and MBT performance in adolescent male basketball players. Coaches should know that such a short resistance training program specifically designed for young basketball players induce increased explosivity levels, which are essential to a better basketball performance, with no extra overload on adolescents' skeletal muscle development.

The Impact of Back Squat and Leg-Press Exercises on Maximal Strength and Speed-Strength Parameters

“…However, results concerning effects in drop jump (DJ) performance are contradictory. Some studies confirm significant performance gains after a strength training intervention (27,57), but others report nonsignificant performance changes (41,43,63). However, medium to strong relationships between strength performance in different exercises of the lower extremities and DJ performances are measurable (10,25).…”

Relationship of body mass status with running and jumping performances in young basketball players

“…Independently from this limitation, it still can evaluate athlete's BM for a given stature, and thus, contribute to BM control. However, BMI is often overlooked in studies in sport populations and there are many studies in basketball players which present data on height and BM, but not on BMI 1,[11][12][13][14][15] . Although basketball is a widely practiced sport worldwide, to the best of our knowledge no study has ever been conducted to investigate the effect of elevated BMI on running and jumping performances in young male basketball players.…”

Research Review of the Development of the Explosive Strength in Basketball // Pregled istraživanja razvoja eksplozivne snage u košarci

“…Santos & Janeira (2012) su na uzorku od 25 košarkaša starosti 14-15 godina utvrdili da trening snage sa tegovima za gornje i donje ekstremitete dovodi do značajnog pobolјšanja rezultata na testovima: squat jump, countermovement jump, abalakov test, drop jump i medicine ball throw. Komal & Singh (2013) su utvrdili da pomenuta metoda treninga može biti efi kasna u poboljšanju eksplozivne snage i kod nešto straijih košarkaša (16-18 godina) nego u prethodnom istraživanju.…”

“…Santos & Janeira (2012) in a sample of 25 basketball players aged 14-15 years found that the strength training with weights for the upper and lower extremities leads to a signifi cant improvement in the results of the tests: squat jump, countermovement jump, Abalak test, drop jump and medicine ball throw. Komal & Singh (2013) found that the aforementioned method of training can also be effective in improving the explosive power of even older basketball players (16-18 years) than in the previous survey.…”
