Farklı yaş kadınlarda step-aerobik egzersizlerinin aerobik kapasite ve beden kompozisyonu üzerine etkisi

Öz

Çalışmanın amacı, ACSM eşitliği doğrultusunda uyarlanmış tempolarda yapılan step-aerobik egzersizlerinin farklı yaş grubundaki kadınların kardiyorespiratuvar (maksVO2) ve beden kompozisyonu özellikleri üzerine etkisini incelemekti. 8 hafta (haftada 3 gün) devam eden çalışmaya 30-41 (Grup 1) yaşları arasında 13 ve 21-26 (Grup 2) yaşları arasında 11 olmak üzere toplam 24 kişi katıldı. Egzersiz temposu yoğunluğunun belirlenmesi için maksVO2 değerleri Bruce test protokolü ile ölçüldü ve ACSM’NİN step için önerdiği metabolik eşitlik ile hesaplandı. Egzersiz programı sonrasında aerobik kapasitedeki değişikliklerin ağırlık, beden kütle indeksi (BKİ) ve beden yağ yüzdesi (%yağ) üzerine etkileri incelendi. Sekiz haftalık step-aerobik egzersiz programının her iki yaş grubu için ağırlık, BKİ ve % yağ üzerinde etkili olduğu ancak bu etkinin egzersiz yoğunluğu ve süresi bakımından istatistiksel olarak anlamlı olmadığı (p>0,05), 2. grup için maksVO2 değerlerinde istatistiksel olarak anlamlı fark ortaya çıkardığı (p<0,05) belirlendi

THE EFFECTS OF STEP-AEROBIC EXERCISES ON AEROBIC CAPACITY AND BODY COMPOSITION IN WOMEN AT DIFFERENT AGES

Abstract

The purpose of present study was to examine the effects of step-aerobic exercise with a tempo which was determined according to ACSM equivalence adjustment, on cardiorespiratory capacity (VO2max), and body composition characteristics of women at different age groups. A total of 24 participants took part in eight weeks (3 days a week) step-aerobic exercises. A total of 24 participants, 13 of whom were between the ages of 30-41 (Group 1), and 11 between the ages of 21-26 (Group 2), participated in the study continued for 8 weeks (3 days a week). The VO2max values which were used to determine the intensity of exercise tempo were measured by the Bruce test protocol, and were calculated by the metabolic equivalent proposed by ACSM for the step exercises. Effects of aerobic capacity changes on weight, body mass index (BMI) and percent body fat (% fat) after exercise program were investigated. It was found that although the 8 weeks of step aerobic exercise program was effective on weight, BMI, and percent body fat for both age groups, this effect was not statistically significant in terms of exercise intensity and duration (p>0.05), and the exercise program led the statistically significant difference on VO2max values for group 2 (p<0.05)
