Bedensel engelli yüzücülerde çıkış süresinin gövde esnekliği, aerobik endurans ve anaerobik güç ile ilişkisi

Öz

Amaç: Bu çalışma, bedensel engelli yüzücülerin yarışa başlangıç sürelerini etkileyen faktörleri belirlemek amacıyla planlandı.
Yöntem: Çalışmaya yaş ortalaması 18,2±3,69 yıl olan, World Para-Swim Sınıflandırma Sistemine göre spor sınıfları S6-S9 arasında değişen 20 bedensel engelli sporcu katıldı. Aerobik endurans değerlendirmesinde 12 dakika yüzme testi (Cooper Test), anaerobik güç değerlendirmesinde dikey sıçrama testi, gövde esnekliği değerlendirmesinde otur uzan, gövde fleksiyon,
gövde rotasyon ve lateral fleksiyon testleri kullanıldı. Değişkenler arasındaki ilişkilerin miktarını saptamak için Pearson ve Spearman korelasyon analizleri kullanıldı.
Bulgular: Çalışma sonucunda sporcuların otur uzan testi ve dikey sıçrama testi ile çıkış süresi arasında negatif yönde orta düzeyli anlamlı ilişki bulundu (r=-0,465, p˂0,05; r=-0,638, p˂0,05). Çıkış süresi ile 12 dakika yüzme testi arasında yüksek düzeyde anlamlı ilişki bulundu (r=-0,695, p<0,001).
Sonuç: Aerobik endurans, alt ekstremite anaerobik gücü ve sırt-bacak esnekliği testlerinde daha iyi performans sergileyen sporcuların daha hızlı çıkış yapabildiği görüldü. Sporcuların su içi çalışmaların yanı sıra esneklik ve alt ekstremite pliometrik egzersizlerini kara antrenman programına ilave etmesi tavsiye edilmektedir.

The relationship between swim-start, trunk flexibility, aerobic endurance and anaerobic power in physically disabled swimmers

Öz

Purpose: The aim of this study was to quantify relationship between physiologic variables and swim start performance in physically disabled swimmers.
Methods: Study included twenty physically disabled sportsmen (mean age 18.2±3.69) between S6-S9 sports classes according to International Classification System. Aerobic endurance was assessed by 12-minute Swim Test (Cooper Test). Anaerobic power was measured by vertical jump test. Flexibility was determined through; sit and reach test, trunk flexion, side flexion and rotation tests. Pearson and Spearman correlation analyzes were used to determine the relationship between variables.
Results: As a result, significant correlation was found between swim start performance and sit and reach test (r=0.465, p<0.05), vertical jump test (r=-0.638, p<0.05). There was a very strong correlation between 12-minute swim test and swim starts performance (r=-0.695, p<0.001).
Conclusion: It has been noticed that, athletes exhibited better performance with aerobic endurance, anaerobic power of the lower extremities and lower back- hamstring flexibility tests able to perform faster start. It is recommended that in addition to pool-based training, flexibility and lower extremity plyometric exercises should be included in dry land training programme.
