Effect of high-intensity interval training on body composition of breast cancer patients treated with chemotherapy. Participants undergoing chemotherapy for breast cancer were assigned to two groups: HIIT – performing high-intensity interval training protocol throughout chemotherapy; CTR, control group – instructed to perform physical activity at volume recommended by World Health Organisation guidelines21. Body composition was measured using bioelectrical impedance analysis before treatment and after finishing treatment. The effect of intervention on the change in body composition was assessed using two-way ANOVA test.
