“…The aim of the present study was to examine bilateral and ipsilateral knee isokinetic strength ratios in elite football players. 30 -1 angular velocity in the comparison of both ipsilateral H/Q and bilateral O/Q and H/H ratios (p<0,05). As a result, it was found that in elite football players, DT sides produced higher strength at all angular velocities when compared with NDT sides and both bilateral and ipsilateral strength differences were found at 60 o sn -1 angular velocity, which requires high strength.…”

“…Mevcut araştırmamızdaki futbolcuların bilateral kuvvet oranları literatüründe rapor edilen güvenilir aralıktadır.Araştırmamızda futbolcuların diz EKS ve FLEK kuvvetlerine bağlı lateral asimetri oranları konvensiyonel olarak Q ve H kasında Kon/Kon kasılmalarla alınmıştır. Ancak futbolun hareket yapısı gereği diz kuvvetinin fonksiyonel olarak yani Q kasında konsantrik, H kasında eksantrik değerlendirme adına daha geçerli bir yöntemdir[29,30]. Konvensiyonel olarak lateral asimetrik oranları değerlendirmek geçerli bir yöntem olsa da mevcut araştırmamızın fonksiyonel yöntemi içermemesi çalışmanın ana sınırlılıklarından biri olarak karşımıza çıkmaktadır.Sonuç olarak, araştırmamızda ki futbolcularda EKS fazında DT tarafın NDT'ye göre daha kuvvetli olduğu, FLEK fazında ise benzer sonuçlar ortaya çıkardığı görülmektedir.…”

Mevcut araştırmanın amacı, elit futbolcularda bilateral ve ipsilateral diz izokinetik kuvvet oranlarının incelenmesidir. Araştırmaya 19-28 yaş aralığında en az 10 yıl futbol antrenman geçmişine sahip ve aktif antrenman yapan 30 erkek (yaş 24,15 yıl, boy 177,59 cm, kilo 72,07 kg ve VKİ 23,09 kg/m2) gönüllü olarak katıldı. Deneklerin bilateral quadpceps/quadriceps (Q/Q) ve ipsilateral hamstring/quadriceps (H/Q) oranlarının hesaplanmasında dominant (DT) ve nondominant (NDT) taraflarına 60osn-1, 180osn-1 ve 240osn-1 açısal hızlarda konsantrik/konsantrik (Kon/Kon) diz ekstansyion (EKS) ve fleksiyon (FLEK) izokinetik kuvvet testi uygulandı. DT ve NDT kuvvetlerinin, bilateral ve ipsilatarel kuvvet oranlarının karşılaştırılması paired sample t-test kullanıldı. Deneklerin 60osn-1, 180osn-1 ve 240osn-1 açısal hızlarda izokinetik diz EKS ve FLEK kuvvetleri DT ve NDT taraflar arasında karşılaştırıldığında 60osn-1, 180osn-1 ve 240osn-1 açısal hızların tümünün EKS fazında DT lehine istatistiksel anlamlıklara rastlandı (p<0,05). Lateral asimetri oranları ise hem ipsilateral H/Q hemde bilateral O/Q ve H/H oranlarının karşılaştırmalarında sadece 60osn-1 açısal hızda anlamlılık tespit edildi (p<0,05). Sonuç olarak, elit futbolcularda DT taraflarının NDT taraflara göre tüm açısal hızlarda daha yüksek kuvvet ürettikleri, yüksek kuvvet gerektiren 60osn-1 açısal hızda hem bilateral hemde ipsilateral kuvvet farklılıkları ortaya çıkardıkları belirlendi. Bu sonuçlara göre futbolcuların hızlı ancak düşük kuvvet gerektiren yüksek açısal hzılarda sakatlık eğilimlerinin her iki ekstremite içinde benzer olduğu, fakat düşük açısal hızlarda hem bilateral hemde ipsilateral asimetrik farklılık ortaya çıkardıkları görüldü. İstatistiksel açıdan anlamlı olmasına rağmen 60osn-1 açısal hızda ortaya çıkan asimetrik farklılıkların literatürde belirtilen ipsilateral için %60-70 bilateral için %90-100 aralığında olması futbolcuların diz sakatlıkları adına güvenli aralıkta olduklarını gösterdi.

Introduction Human motor dysfunction can affect the quality of life, especially waist dysfunction. And an effective means to improve muscle strength during exercise. Object This article compares and analyzes the effectiveness of human muscle exercise on the decline in quality of life caused by motor dysfunction. Method The article divides patients with motor dysfunction into trunk isokinetic training group (experimental group) and waist and abdominal muscle functional training group (control group), and comparative analysis of related indicators before and after treatment. Results Before treatment, the specific indicators of the two were different (P>0.05). After treatment, the patients’ quality of life indicators and motor function indicators were significantly different (P<0.05). Conclusion Exercise has an obvious curative effect for patients with human motor dysfunction, and it is worthy of clinical promotion. Level of evidence II; Therapeutic studies - investigation of treatment results.

BackgroundStudies have grouped different overhead sports and evaluated together the isokinetic strength of shoulder internal (IR) and external (ER) rotator muscles. However, muscular adaptations could be a consequence of the specific sport, and some strength imbalance between these muscles may exist as a consequence of the muscular demand unique to the sport. Therefore, grouping different overhead sports together may not be adequate. PurposeTo compare strength balance ratios between different overhead sports (volleyball, handball, swimming, judo, baseball, softball, functional movements performed at high-intensity interval training, and tennis) with a control athletic group (no overhead group). Study designCross-sectional study. MethodsA total of 237 athletes were submitted to isokinetic shoulder strength tests. The isokinetic concentric and eccentric peak torque values of shoulder internal IR and external ER rotator muscles were measured. Conventional (CR) and functional strength ratios (FR) were calculated. ResultsThere were no significant differences between the sports for the CR in the male group. Female softball athletes (90.4±13.6%) had a significantly higher CR than judo (67.3±6.9%), volleyball (74.9±15.9%), and swimming athletes (70.3±8.7%). In the female group, judo athletes had lower FR values (0.76±0.19) than soccer athletes (1.31±0.35), volleyball athletes (1.24±0.27), functional movements performed at high intensity (1.10±0.1), and softball athletes (1.40±0.39). Female handball athletes also had a lower FR (0.99±0.25) than soccer athletes (1.31±0.35) and softball athletes (1.40±0.39). Male handball (0.90±0.23), tennis (0.86±0.30), and judo (0.68±0.22) athletes had lower FR values than soccer athletes (1.20±0.21) and volleyball athletes (1.25±0.28). ConclusionsCR for males may be analyzed together, as there were no significant differences between them. However, for females, the CR for softball athletes should be analyzed individually. As there were several differences between the overhead sports according to the FRs, the authors suggest caution in grouping overhead athletes across multiple sports. These
