Abstract

The aim of the study is to identify the effects of lower and upper extremity plyometric training on maximal strength and body fat ratio of young basketball players, in a 9 week period. 30 male basketball players voluntarily participated in the study. The sample group was distinguished into the control group (n = 15; age = 14.7 ± 0.97) and the test group (n = 15; age = 14.8 ± 0.54) by randomization. Body height, body weight and body fat ratio of each participant was measured. Maximal strength levels were determined by testing 1 repeat maximum (1 TM) leg press, 1 TM leg curl, 1 TM bench press, 1 TM overhead press and 1 TM high pulley. In addition, the jump strength of the participants was determined by the counter movement jump (CMJ) test. Core strength was determined by the Sport-Specific Core Muscle Strength and Stability Plank Test. Two way repeated measures analysis of variance (ANOVA) was performed to test the combined effect of group (intervention and control) and measure (pre-test and post-test). There was a significant difference between groups according to the body height variable. (F(1-28) = 5.27, p<.05). There was no significant difference between groups according to body weight and body fat percentage variables (F(1-28) = 1.86; 5.22, p>.05; respectively). Significant differences were found in favor of the test group according to 1 RM leg curl, CMJ, 1 RM bench press, 1 RM overhead press, 1 RM high pulley variables. (F(1-28) = 16.13; 5.20; 4.65; 4.59; 14.7, p<.05; respectively). Additionaly, There was no significant difference between groups according to leg press and plank variables. (F(1-28) = 0.77; 0.02, p>.05; respectively). Consequently, the lower and upper extremity plyometric training program contributed to the improvement of the strength level of young basketball players.

THE EFFECT OF LOWER AND UPPER EXTREMITY PLYOMETRIC EXERCISE PROGRAM ON MAXIMAL STRENGTH AND BODY FAT RATIO OF YOUNG BASKETBALL PLAYERS

Abstract

Araştırmanın amacı genç basketbolculara 9 hafta boyunca uygulanan alt ve üst ekstremite pliometrik antrenman programının maksimal kuvvet düzeylerine ve vücut yağ oranlarına etkisini belirlemektir. Araştırmaya 30 erkek basketbolcu gönüllü olarak katılmıştır. Örneklem grubu randomizasyon yöntemi ile kontrol grubu (n = 15; yaş = 14,7±0,97) ve deney grubu (n = 15; yaş = 14,8±0,54) olmak üzere iki gruba ayrılmıştır. Katılımcıların boy uzunluğu, vücut ağırlığı ve vücut yağ yüzdeleri ölçülmüştür. Maksimal kuvvet düzeyleri 1 tekrar maksimum (1 TM) leg press, 1 TM leg curl, 1 TM bench press, 1 TM overhead press ve 1 TM high pulley testleri ile belirlenmiştir. Ayrıca katılımcıların sıçrama kuvveti counter movement jump (CMJ) testi ile belirlenmiştir. Core kuvveti ise Sport-Specific Core Muscle Strength and Stability Plank Testi ile belirlenmiştir. Grubun (test ve kontrol) ve ölçümün (ön test ve son test) kombine etkisini test etmek için iki yönlü tekrarlanan ölçümler varyans analizi (ANOVA) yapıldı. Kontrol ve deney grubunun boy uzunluğu değişkeni açısından grup-ölçüm ortak etkisi incelendiğinde gruplar arasında anlamlı bir farklılık tespit edilmiştir (F(1-28) = 5,27, p<,05). Vücut ağırlığı ve vücut yağ yüzdesi değişkenleri açısından grup-ölçüm etkisi incelendiğinde ise gruplar arasında anlamlı bir farklılık tespit edilmemiştir (sırasıyla; F(1-28) = 1,86; 5,22, p>,05). Grupların 1 TM leg curl, CMJ, 1 TM bench press, 1 TM overhead press, 1 TM high pulley değişkenleri ile grup-ölçüm sonuçları incelendiğinde deney grubu lehine anlamlı farklılıklar tespit edilmiştir (sırasıyla; F(1-28) = 16,13; 5,20; 4,65; 4,59; 14,7, p<,05). Pliometrik antrenman programının leg press ve plank değişkenleri üzerindeki grup-ölçüm ortak etkileri incelendiğinde gruplar arasında anlamlı bir farklılık tespit edilmemiştir (sırasıyla; F(1-28) = 0,77; 0,02, p>,05). Sonuç olarak; alt ve üst ekstremite pliometrik antrenman programı genç basketbolcuların maksimal kuvvet düzeylerinin gelişmesine katkı sağlamıştır.
