Effectiveness of a 12‐week tele‐exercise training program on cardiorespiratory fitness and heart rate recovery in patients with cardiometabolic multimorbidity

摘要

Abstract Background Exercise has positive impacts on cardiometabolic health. However, evidence regarding the effectiveness of tele‐exercise training on cardiorespiratory fitness and heart rate recovery in patients with cardiometabolic multimorbidity remains limited. Aims The aim of this study was to assess whether an assumed increase in physical activity (PA) after a 12‐week tele‐exercise training program improved cardiorespiratory fitness and heart rate recovery of patients with cardiometabolic multimorbidity. Methods A parallel‐group randomized controlled trial was conducted. Eligible patients with cardiometabolic multimorbidity (n?=?83) were randomized 1:1 to either an experimental group (EG, received a 12‐week tele‐exercise training program with 3 sessions/week and 30?min/session and weekly remote monitoring for maintenance of exercise) or a control group (CG, usual care only). PA, cardiorespiratory fitness, and heart rate recovery were assessed at baseline and 12?weeks. Generalized estimating equations were used to examine the intervention effects via the interaction of time and group. Results Sixty‐eight participants (81.9) completed the study, and 83 were included in the intention‐to‐treat analysis. The EG with higher vigorous‐intensity PA (β?=?714, p?=?.037), walking behavior (β?=?750, p?=?.0007), and total amount of PA (β?=?1748, p?=?.001) after the intervention had significantly elevated cardiorespiratory fitness, including VO2peak (β?=?3.9, p?=?.042), workload (β?=?17.9, p?=?.034), and anaerobic threshold (β?=?2.1, p?=?.041), and increased one‐min heart rate recovery (β?=?5.3, p?=?.025), compared with the CG. Linking evidence to action A 12‐week tele‐exercise training program was effective for increased PA, elevated cardiorespiratory fitness, and improved heart rate recovery for patients with cardiometabolic multimorbidity. These findings highlight the feasibility of better delivering lifestyle interventions for cardiometabolic health management.
