BACKGROUND: This randomised, controlled non-inferiority trial investigated whether 8 weeks of remotely-supported exercise training changes cardiorespiratory fitness, functional fitness and body composition by a magnitude that is not meaningfully inferior to changes caused by partly-supervised exercise training.
METHODS: Thirty female breast cancer survivors (57 ± 6 years, V ̇ O 2 max $$ \dot{\mathrm{V}}{\mathrm{O}}_2\max $$ 28.9 ± 6.1 mL·kg-1·min-1, BMI 25.3 ± 3.3 kg·m-2) were randomised to 8 weeks of partly-supervised (n = 15) or remotely-supported (n = 15) exercise training. The partly-supervised group undertook two supervised and one unsupervised session per week, progressing from 55% to 70% V ̇ O 2 max $$ \dot{\mathrm{V}}{\mathrm{O}}_2\max $$ and 35-50 min. The remotely-supported group were prescribed the same total duration of exercise per week (progressing from 105 to 150 min). Intensity was prescribed using heart rate targets corresponding to 55%-70% V ̇ O 2 max $$ \dot{\mathrm{V}}{\mathrm{O}}_2\max $$ . V ̇ O 2 max $$ \dot{\mathrm{V}}{\mathrm{O}}_2\max $$ , functional fitness, body composition and blood pressure were assessed pre- and post-intervention.
RESULTS: Adherence was higher in the partly-supervised group (87% ± 7%) versus the remotely-supported group (64% ± 25%; p = 0.01). The remotely-supported group exhibited changes in timed up and go (difference to partly-supervised; 95% CI -0.8 to 0.4 s) and percentage body fat (difference to partly-supervised; 95% CI -0.6 to 0.5 kg·m-2) that were non-inferior to the partly-supervised group. It was inconclusive whether changes among the remotely-supported group for V ̇ O 2 max $$ \dot{\mathrm{V}}{\mathrm{O}}_2\max $$ (difference to partly-supervised; 95% CI -3.3 to 1.1 mL·kg-1·min-1), blood pressure (difference to partly-supervised; 95% CI systolic; -3 to 12 mmHg, diastolic; -5 to 6 mmHg), 6 min walk (difference to partly-supervised; 95% CI -54.0 to 0.4 m), or sit to stand (difference to partly-supervised; 95% CI -3 to 2 repetitions), were non-inferior to the partly-supervised group.
CONCLUSION: Remotely-supported exercise might be an alternative to partly-supervised exercise regarding functional fitness (assessed by timed up and go) and body composition (assessed by percentage body fat). It remains inconclusive whether remotely-supported exercise is an alternative regarding V ̇ O 2 max $$ \dot{\mathrm{V}}{\mathrm{O}}_2\max $$ , blood pressure and other functional fitness measurements (6-min walk, sit to stand).
