Interval training during concurrent training optimizes cardiorespiratory adaptations in women

Abstract This study compared the effects of using continuous and interval aerobic exercise during concurrent training on cardiorespiratory adaptations in women. Thirty-two participants were randomly assigned into one following groups: running resistance (C-RUN, n = 10), (I-RUN, 11), or control group that performed only (RT, 11). Each trained twice a week 11 weeks. Oxygen uptake corresponding to first ventilatory threshold (VO2VT1), second (VO2VT2) maximal effort (VO2max) was measured incremental test before after training. Significant increases VO2VT1, VO2VT2 VO2max observed all groups. presented time-group interactions, indicating magnitude increase these variables dependent (VO2VT2: C-Run 6.6%, I-Run 15.7%, RT 1.7%; VO2max: 7.2%, 14.3%, 2.7%). The effect size for post-training values comparing C-RUN groups d 0.566 0.442 VO2max. On other hand, 0.949 1.189 verified between I-RUN In conclusion, use improved different parameters women, but greater when simultaneously
