The Effect of Aerobic and Core Exercises on Forced Vital Capacity

Abstract The aim of the study was to investigate the effect of aerobic and core strength exercises on forced vital capacity in sedentary women. A total of 40 healthy sedentary women (20 in an aerobic-step group and 20 in a core strength exercise group) with a mean age of 34.4±2.4 years participated voluntarily in this study. Two different exercises were applied to the women for 12 weeks, 4 days a week, at the intensity of 70% for 60 minutes. The womens resting heart rate (RHR), maximal oxygen consumption (VO2max), forced vital capacity (FVC), and forced air volume in the first second of forced expiration (FEV1) were measured before and after exercise. For statistical analysis, the Paired Samples-t test was used for intra-group evaluations, and the Independent Samples-t test was used for inter-group evaluations. After the exercise program, significant increases were found in the VO2max, FVC, and FEV1 values, while both groups experienced a decreased RHR (p<0.01). Since the aerobic and forced vital capacities of the sedentary women show a parallel increase as a result of the applied 12-week aerobic and core strength exercises, it can be said that the RHR, VO2maxmax, FEV, and FEV1 respiratory parameters also improved in a positive manner. For this reason, it may be advisable to apply both exercise types for the development of the aerobic and vital capacities of sedentary women.

Yüzücü ve Sedanter Çocukların Vücut Kompozisyonu ve Bazı Fizyolojik Parametrelerinin Karşılaştırılması

Bu calismanin amaci yuzucu ve sedanter cocuklarda bazi fiziksel ve fizyolojik parametreleri karsilastirmaktir. 16 yuzucu cocuk (ortalama yaslari: 10,75±1,34 yil, boy: 146,56±9,16 cm, vucut agirligi: 42,76±14,05 kg ve spor yasi 26.31±10.22 ay ) ve 17 sedanter erkek cocuk (ortalama yaslari: 10,65±1,27 yil, boy: 140,41±8,32 cm, vucut agirligi: 38,15±10,94 kg) olan toplam 33 saglikli ve gonullu cocuk bu calismaya katildi. Bu calismada vucut agirligi, beden kutle indeksi (BKI), bazal metabolik hizi (BMH), vucut yag kutlesi (VYK) ve vucut yag yuzdesi (VYY) bioelektrik impedans analizi (Tanita) ile belirlendi. MaxVO 2 icin Bruce protokolu, kan basinci oncesi ve sonrasi, el kavrama, otur- eris ve dikey sicrama testleri uygulandi. Gruplar arasi karsilastirmada istatiksel olarak onemlilik seviyesi p<0.05 kullanildi. Yuzucu cocuk ve sedanter cocuklarin test degerleri karsilastirildiginda Bruce protokolunden sonra MaxVO2 ve dikey sicrama, sistolik ve diyastolik kan basinclari degerlerinde anlamli farklilik bulundu (p<0.05). Sonuc olarak, yuzucu cocuklarin kan basinci, aerobik ve anaerobik kapasiteleri sedanter cocuklardan daha iyi oldugu bulundu. Bunun sebebi olarak yuzme sporunun duzenli olarak yapilmasinin 10-13 yas grubu erkek cocuklarda aerobik ve anaerobik kapasiteler ile sistolik ve diastolik kan basinci parametreleri uzerinde olumlu bir etki sagladigi soylenebilir.

The effect of exercises on left ventricular systolic and diastolic heart function in sedentary women: Step-aerobic vs core exercises

The purpose of this study is to investigate the effect of 16 weeks step-aerobic exercises and core exercises on left ventricular structure and function with some physiological parameters in sedentary women. Methods To achieve the purpose of this study, a total of 45 volunteers including (step-aerobic group (SAG, n = 25), core exercise group (CEG, n = 20) were selected as participants. Two different exercises were applied for 4 days a week, throughout 16 weeks, within 60 minutes for each exercise with the intensity of heart rate (HR) 60-70 percent. The HR was measured using a heart rate monitor for each subject. The physical, biochemical and echocardiographic characteristics of the women were measured before and after the exercise. Results During the exercise periods, there were a meaningful decrease in the body weight, BMI, value of waist region and hip circumference of the women in both intervention groups as well as in the values of HR, DBP, SBP (p < 0,05). In addition, serum homocysteine (Hcy) and high-sensitivity C-reactive protein (Hs-CRP) levels decreased and the VO2max and left ventricular diastolic end-diastolic dimension increased in both SAG and CEG (p < 0.05). The left ventricular diastolic functions of the SAG improved more than CEG. Left ventricular systolic ejection time and fractional shortening meaningfully improved in both SAG and CEG (p < 0.01). Conclusion 16 weeks of step-aerobic and core exercise showed significant changes of inflammatory and lipid markers with cardiac dimensions and had favorable effects on both left ventricular systolic function. Left ventricular diastolic function had more improved in SAG than the CEG.
