The Effect of Isoinertial Training on Jumping Performance on Young Football Players

Öz

Aim: Strength and power-related variables are essential mechanisms of performance that require jumping in football. Isoinertial training has been an important training method for improving power performance. The aim of the study is to observe the effect of eight-week isoinertial training on jumping in young football players.

Methods: Twenty-four volunteer male football players playing in the Turkish Football Federation (TFF) U19 Development League 1st League group were divided into two groups as training group (age: 16.91±0.72 years, height: 176.42±6.02 cm, body weight: 71.17±7.11 kg, BMI: 23.80±2.20 kg/m2) and isoinertial group (age: 16.83±0.39 years, height: 176.17±6.13 cm, body weight: 68.28±5.69 kg, BMI: 22.02±1.77 kg/m2). The training group performed exercises consisting of four sets, six repetitions, and five movements (squat, right/left lunge, right/left side lunge) with their body weight. The isoinertial group performed, same training with the isoinertial training device at 80% of the maximal intensity. The training groups performed the exercises two days a week for eight weeks, a total of sixteen training, during the training period. We measured the athletes’ performance with a jump meter (Takai, Japan) device before and after the eight-week training. Paired simple t-test was used to compare the pre-test and post-test of the groups. Independent simple t-test analysis was used for comparisons between groups.

Results: The jumping grades of the group isoinertial training have increased (p<0.05). However, the jumping grades of the training group not have increased (p>0.05).

Conclusion: The result of the research showed that the eight-week isoinertial exercises that the young football players will do in addition to their training increase the jump height.

Genç Futbolcularda İzoinertial Antrenmanların Sıçrama Performansına Etkisi

Öz

Amaç: Kuvvet ve güçle ilgili değişkenler, futbolda sıçramayı gerektiren temel performans mekanizmalarıdır. İzoinertial antrenman, güç performansının iyileştirilmesi için önemli bir antrenman yöntemidir. Bu nedenle bu çalışmada genç futbolcularda sekiz haftalık izoinertial antrenmanının sıçramaya etkisini araştırılmıştır.

Materyal ve Metot: Türkiye Futbol Federasyonu (TFF) U19 Gelişim Ligi, 1. Lig grubunda oynayan, gönüllü Yirmi dört erkek futbolcu, antrenman grubu (yaş: 16.9±0.717 yıl, boy: 176.42±6.02 cm, vücut ağırlığı: 71.17±7.11 kg, VKİ: 23.80±2.20 kg/m2) ve izoinertial grubu (yaş: 16.83±0.39 yıl, boy:176.17±6.13 cm, vücut ağırlığı: 68.28±5.69 kg, VKİ:22.02±1.77 kg/m2) olmak üzere iki gruba ayrılmıştır. Antrenman grubu vücut ağırlıkları ile dört set, altı tekrar ve beş hareketten (squat, sağ/sol lunge, sağ/sol yan lunge) oluşan egzersizleri yapmıştır. İzoinertial grubu, antrenman grubunun egzersizlerine ek olarak, izoinertial antrenman cihazı ile maksimum şiddetin %80'inde antrenman yapmıştır. Antrenman grupları, sekiz haftalık antrenman süresi boyunca haftada iki gün toplam on altı uygulama yapmıştır. Sekiz haftalık antrenmandan önce ve sonra sporcuların performansları sıçrama ölçer (Takai, Japonya) cihaz ile ölçülmüştür. Grupların ön ve son testlerinin karşılaştırılmasında bağımlı gruplarda t test kullanıldı. Gruplar arası karşılaştırmalarda bağımsız gruplarda t test analizi kullanıldı.

Bulgular: İzoinertial antrenmanları yapan grubunun sıçramaları artmıştır (p<0.05). Ancak antrenman grubunun sıçramalarında gelişim olmamıştır (p>0.05).

Sonuç: Araştırmanın sonucu, futbolcuların antrenmanlarına ek olarak yapacakları sekiz haftalık izoinertial egzersizler futbolcuların sıçrama yüksekliğini arttırmıştır.
