Purpose This exploratory study aimed to examine the potential effects of a 12-week progressive whole-body resistance exercise training (RET) program on measured submaximal oxygen consumption (submaximal VO2) and work efficiency during the 6-min walk test (6MWT) in healthy postmenopausal women and breast cancer survivors. Methods Twenty-four postmenopausal women (Healthy, HEA; 54 +/- 3 years; BMI 26.6 +/- 2.7 kg<middle dot>m(-2); n = 13 and breast cancer survivors, BCS; 52 +/- 5 years; BMI 26.8 +/- 2.1 kg<middle dot>m(-2); n = 11) completed a 12-week RET program. Participants were assessed using the 6MWT with a PNOE (R) metabolic analyzer before and after the intervention. Metabolic and respiratory parameters, including submaximal VO2 and work efficiency were measured. Data were analyzed using repeated measures ANOVA. Results Twelve-week RET improved the distance covered in the 6MWT by 10 +/- 11% in the HEA group (from 586.6 +/- 27.9 to 642.9 +/- 35.9 m) and by 6 +/- 16% in the BCS group (from 572.9 +/- 62.6 to 604.7 +/- 39.9 m) (P < 0.001; eta(2) = 0.54), with no significant differences between the groups (P = 0.175). There was an increase in RER (P < 0.001), ventilation (P = 0.043), and carbohydrate percentage (P < 0.001), along with a decrease in fat consumption percentage (P < 0.001), with no differences between groups (P > 0.05). After 12 weeks of RET, absolute submaximal VO2 decreased in both groups (P < 0.001), with no differences between them (P > 0.05). The maximum work rate increased (P < 0.001), with no differences between groups (P > 0.05). Work efficiency also improved over time (P < 0.05), with no differences between groups (P > 0.05). Conclusion As an exploratory analysis, these findings suggest that a 12-week RET program improved work efficiency and reduced measured submaximal VO2 during the 6MWT in both populations. The improvements were similar in healthy postmenopausal women and breast cancer survivors. (AU) | |
