Effects of Weighted Versus Standard Jump Rope Training on Physical Fitness in Adolescent Female Volleyball Players: A Randomized Controlled Trial

Abstract

Purpose: The aim of this study was to compare the effects of 12-week standard versus weighted jump rope training on physical fitness tests including anaerobic power, speed, agility and flexibility in female adolescent volleyball players.Methods: Twenty-five female volleyball players were recruited to the study. Participants were randomly separated into three study groups; weighted jump rope training (n=8), standard jump rope training (n=9) and control group (n=8). All participants were assessed at baseline and after 12-week training. Physical fitness was measured by using vertical jump test, 30-meter sprint test, hexagonal obstacle test, zigzag test and sit and reach test. Repeated-measures ANOVA was used for statistical analysis. Results:Comparisons showed that after 12-week training, weighted jump-rope training resulted in higher improvements in anaerobic power (p=0.03) and agility (p=0.003) when compared to control training; and higher improvement in agility when compared to standard jump rope training (p=0.001). In addition, at the end of training, speed and flexibility gains were similar in all groups (p>0.05).Discussion: Weighted jump rope training resulted in higher improvements of anaerobic power and agility in female adolescent volleyball players. The findings of the study provide basic knowledge for developing training protocols for adolescent volleyball players. Yöntemler: Yirmi beş kadın voleybol oyuncusu çalışmaya dahil edildi. Katılımcılar ağırlıklı ip atlama (n=8), standart ip atlama (n=9) ve kontrol grubu (n=8) olmak üzere 3 gruba ayrıldı. Tüm katılımcılar eğitim öncesi ve 12 haftalık eğitimin ardından tekrar değerlendirildi. Fiziksel uygunluk, dikey sıç-rama, 30 metre sprint, beşgen engel, zikzak test ve otur-uzan testleri kullanılarak değerlendirildi. İstatistiksel analizde ANOVA kullanıldı. Sonuçlar:On iki haftalık eğitimin ardından ağırlıklı ip atlama grubunda kontrol grubu ile karşılaş-tırıldığında anaerobik güç (p=0.03) ve çeviklikte (p=0.003); standart ip atlama grubu ile karşılaş-tırıldığında ise çeviklikte (p=0.001) daha fazla gelişme kaydedildi. Ayrıca, eğitim sonucunda hız ve esneklik kazanımı tüm gruplarda benzer bulundu (p> 0.05).Tartışma: Adolesan kadın voleybol oyuncularında ağırlıklı ip atlama eğitimi anaerobik güç ve çe-viklikte daha fazla kazanım ile sonuçlanmıştır. Bu çalışmanın bulguları, adolesan voleybol oyuncuları için eğitim protokolleri geliştirilmesinde temel bilgi sunmaktadır.Anahtar kelimeler: Adolesan; pliometrik egzersiz; sporcu sağlığı; voleybol.

The Effect of Plyometric Training in Volleyball Players: A Systematic Review

“…The participants of these two studies were female youth volleyball players. One study was a cohort study with a 12-week intervention period [43], and the other was a randomized controlled trial which also had an intervention period of 12 weeks [45]. The results of these studies reveal that plyometric training can improve flexibility by 9% [43] to 14% [45].…”

“…This systematic review found three studies which observed the effects of plyometric training on the agility/speed of volleyball players [43,46,47]. The results can be found in Table 6.…”

“…The results can be found in Table 6. The tests used in these studies included a 20 m sprint [43], a zigzag double-leg jump over the line combined with a shuttle run (6 m × 6 m) [46], and a shuttle run for which the distance was not reported [47].…”

The Effects of the Rope Jump Training Program in Physical Education Lessons on Strength, Speed and VO₂ max in Children

“…As a result of the study, 20-m speed values were significantly lower in the rope-jump group than in the control group (p<0.05). Turgut et al (2016) conducted a study on adolescent volleyball players, and determined that there were significant increases in the anaerobic strength and speed values of the study group when compared with the control group after a 12-week rope and weighted-rope trainings [23]. Endo et al (2007) reported that when the rope-jump was used in an efficient way in the growth attack period between 9 and 13 age group, the sprint performance values increased [24].…”

“…Düzgün et al (2010) conducted a study on adolescent volleyball players, and reported that weighted-rope-jump training programs increased the shoulder (scapula) outer rotation strength levels [27]. Turgut et al (2016) conducted a study on adolescent volleyball players and reported that Rope-Jump trainings provided advantage in strength and agility [23]. As a result of 12-week rope and weighted-rope trainings, significant increases were determined in the anaerobic strength and speed values in the weighted-rope-jump group when compared with the control group.…”
