Kano ve Halterde İzometrik ve Balistik Performans

Öz

Halter sporcuları kuvvet ve güç üretimini dikey (vertikal) düzlemde gerçekleştirirken, kanocular yatay (horizontal) düzlemde kuvvet ve güç üretirler. Çalışmanın amacı, kuvvet ve güç üretiminin farklı düzlemlerde gerçekleştiği halter ve kano sporlarında sporcuların izometrik kuvvet ve balistik güçleri arasındaki farkı incelemektir. Çalışmaya 14-21 yaş arası 84 sporcu dahil edildi. Sporcuların demografik bilgileri bir iş gününde alınmış ve standart bir ısınma protokolü uygulanmıştır. Balistik kuvveti değerlendirmek için Dinamik Güç İndeksi (DSI) hesaplandı. DSI için veriler Opto-Jump cihazı ile karşı hareket sıçrama (CMJ) testi ve İzometrik Orta Uyluk Testi (IMTP) ile elde edildi. İzometrik kuvveti değerlendirmek için Kistler+Noraxon Ölçüm Cihazı ile IMTP testi yapıldı. Çalışmanın bulgularına göre, erkek halter sporcularının balistik kuvvet, sıçrama yüksekliği ve DSI değerleri erkek kano sporcularından daha yüksek değerlere sahipti (p<0,05). İzometrik kuvvetleri arasında ise anlamlı bir farklılık yoktu (p>0,05). Kadın halter sporcularının sıçrama yüksekliği ve DSI değerleri kadın kano sporcularından daha yüksek bulunurken (p<0,05), izometrik ve balistik kuvvetleri arasında anlamlı bir farklılık yoktu. Sonuç olarak dikey yönde güç üreten halterciler, sıçrama yeteneklerinde güçlerini daha net ortaya koymaktadır.

Isometric and Ballistic Performance in Canoeing and Weightlifting

Abstract

Weightlifters produce strength and power in the vertical plane, while canoeists produce strength and power in the horizontal plane. The purpose of the study is to examine the difference between isometric strength and ballistic force of athletes in weightlifting and canoeing, at which strength and power production occurs in different planes. 84 athletes aged 14-21 were included in the study. Demographic information of the athletes was taken on a working day and a standard warm-up protocol was applied. Dynamic Strength Index (DSI) was calculated to evaluate the ballistic force. Data for DSI were obtained by Opto-Jump device with counter-movement jump (CMJ) test and Isometric Mid-Thigh Test (IMTP). The IMTP test was performed with the Kistler+Noraxon Measurement Device to evaluate isometric strength. According to the findings of the study, the ballistic force, jump height and DSI values of male weightlifters had higher values than male canoe athletes (p<0.05). There was no significant difference between isometric strengths (p>0.05). While the jump height and DSI values of female weightlifters were higher than female canoe athletes (p<0.05), there was no significant difference between isometric and ballistic strengths. As a result, weightlifters, who produce power in the vertical direction, reveal their strength more clearly in their jumping abilities.
