The Influence of 2 Weeks of Low- Volume High - İntensity İnterval Training on Aerobic Indices in Women

Recently, a novel type of high-intensity interval training known as sprint interval training has demonstrated increases aerobic and anaerobic performance. However It has not been done sufficient number of study which investigated the effects of high intensity interval training on women's aerobic fitness. This study aimed to establish the effects of 2-week high intensity interval training on aerobic fitness of women. Ten adolescent women (23.37±1,505years), completed 6 sessions of Wingate -style high intensity interval training over a 2-week period. The first and last session consisted of four sprints. Each training session involved a 10 min warm-up followed by a HIIT program consisting of 6x30s all-out sprint a 4 min recovery. A 5 min cool down period was then performed. On the purpose of determine VO2max (maximal oxygen uptake), VO2peak (peak oxygen uptake) and TTE (time to exhaustion) all subject performed maximal oxygen consuption test in beginning and in the end of the study. A paired t-test was used to determine the differences in aerobic parameters between preand postvalues. Significant improvements (p<0.05) were found by the end of eight week, MaksVo2 (%4.44), peakVo2 (%8.09), and TTE(%7.4) following the HIIT program among subjects. Results showed that two-week wingate style of high intensity interval training program very effective on aerobic indices.
