Effects of plyometric and pull training on performance and selected strength characteristics of junior male weightlifter

Abstract

Purpose: The aim of this study was to investigate the effect of plyometric and pull training added an Olympic weightlifting training program (twice a week for 8 wk) on performance and selected strength characteristics in junior male weightlifter. Material: The participants [n = 34; age: 16.03 ± 0.9 y; mass: 74.78 ± 14.86 kg; height: 170.53 ± 6.81 cm] were randomized into a pull (n = 11), a plyometric (n = 12), and a control (n= 11) groups. The groups trained 6 days a week during the 8-week study period. The pull group performed four pull exercises and the plyometric group performed four plyometric exercises added to Olympic weightlifting program for 2 days a week, and the control group performed an Olympic weightlifting program alone. Analysis of variance and Magnitude-based inferences used to determine whether a significant difference existed among groups on snatch clean and jerk total (SCT), squat (SQ), back strength (BS), countermovement jump (CMJ), 30 sec. repeated jump height (RJH) and peak barbell velocity (PV). Results: The ANOVA showed a time × group interaction for SCT, BS and RJH. The MBI indicated positive changes for SCT in control group, for BS in pull group and for RJH in plyometric group. The results for the PV decrease in plyometric and pull group indicated no significant time × group interaction, but there was a significant main effects.

National Strength and Conditioning Association Position Statement on Weightlifting for Sports Performance

“…Numerous training interventions have been published in which researchers have reported the improvements in sport and related performance (e.g., jump, sprint, and COD) being associated with the implementation of weightlifting-based training methods (10)(11)(12)37,38,40,44,127,131,(137)(138)(139)142,143,216,217,227,236,274,293,294,305,310). In addition, the authors of a recent metaanalysis concluded that weightlifting training results in greater (g $ 0.95) improvements in maximum strength, jump height, linear sprint, and COD performance when compared with traditional resistance training (202).…”

“…The results of several surveys of strength and conditioning coaches have highlighted the perceived importance of prescribing weightlifting exercises and their derivatives (79)(80)(81)(82)(83)259). The results of these surveys are not surprising because combining weightlifting exercises and their derivatives with traditional resistance training exercises (e.g., squat and deadlift variations) has been reported to provide a superior training stimulus over other forms of resistance training, ultimately resulting in greater improvements in sporting tasks (e.g., jumping, short sprint, and COD performance) (10)(11)(12)24,37,38,40,44,127,131,(137)(138)(139)142,143,216,217,227,236,293,294,305,310). Strength and conditioning coaches must, however, decide which exercise and load combinations will address specific training goals (e.g., strength-endurance, strength-speed, and speed-strength) while also considering the athlete's technical competency, mobility, relative strength, and injury status.…”

“…Skuat egzersizleri ise geleneksel antrenman programlarında en fazla yer alan yardımcı egzersizlerdir ve skuat testi kolay uygulanabilir bir testtir. 22 Bu sebeplerle araştırmada, genç haltercilerde vücut kompozisyonu, bar zirve güç çıktısı ve dikey sıçrama testlerinin koparma ve silkme toplam (KST) tahmin etme gücünün belirlenmesi amaçlanmıştır.…”

“…[36][37][38] Halterde kuvvet, bir kaldırış için gerekli olduğu kadar, tolere edilebilir seviyede, hatalı yapılan kaldırışlarda vücudun ve barın hem statik hem de dinamik dengesinin korunabilmesi için gereklidir. 22 Halter teknikleri "koparma" ve "silkme"de en aktif kaslar çoğunlukla kuadriseps kas grubunu kapsamaktadır. Yoğun antrenmanlar sonunda en büyük adaptasyon bu kas grubunda gerçekleşmektedir.…”

“…Dolayısıyla bu yüksekliği üretebilecek güç çıktısının üretilmesi en kritik faktördür. 22 Güç, iş/zaman veya kuvvet × hız olarak tanımlanabilir. Zirve (anlık) güç, belirli bir koşul altında kısa bir süre boyunca belirli bir harekette üretilen maksimum gücü temsil eder ve hem kuvvet hem de hız optimum değerlerde olduğunda üretilmiş olur.…”
