Objectives: The aim of the current study was to investigate the impact of individualised versus standardised combined endurance and resistance training on the fitness-fatness index in physically inactive adults., Design: Randomised controlled trial., Methods: Fifty-four participants aged 21-55 years were randomised into three groups; 1) non-exercise control (n = 18), 2) standardised moderate-intensity continuous training (n = 18), or 3) individualised moderate-intensity continuous training + high-intensity interval training (n = 18). The fitness-fatness index was calculated by dividing cardiorespiratory fitness (expressed as metabolic equivalents) by the waist-to-height ratio. Participants were classified as likely responders to the intervention if a change of ≥1 fitness-fatness index unit was achieved., Results: The individualised group showed the greatest fitness-fatness index improvement (between group difference p < 0.001), with 100 % of this group classified as likely responders, compared to the standardised (68 %) and non-exercise control (0 %) groups., Conclusions: An individualised, threshold-based exercise programme may produce more favourable changes in the fitness-fatness index than a standardised exercise programme., Competing Interests: Declaration of interest statement The authors declare no conflict of interest., (Copyright © 2024.

Introduction: Centre-based cardiac rehabilitation (CR) programs were disrupted and urged to adopt telehealth modes of delivery during the COVID-19 public health emergency. Previously established telehealth services may have faced increased demand. This study aimed to investigate a) the impact of the COVID-19 pandemic on CR attendance/completion, b) clinical outcomes of patients with cardiovascular (CV) diseases referred to CR and, c) how regional and rural centre-based services converted to a telehealth delivery during this time., Methods: A cohort of patients living in regional and rural Australia, referred to an established telehealth-based or centre-based CR services during COVID-19 first wave, were prospectively followed-up, for ≥90 days (February to June 2020). Cardiac rehabilitation attendance/completion and a composite of CV re-admissions and deaths were compared to a historical control group referred in the same period in 2019. The impact of mode of delivery (established telehealth service versus centre-based CR) was analysed through a competitive risk model. The adaption of centre-based CR services to telehealth was assessed via a cross-sectional survey., Results: 1,954 patients (1,032 referred during COVID-19 and 922 pre-COVID-19) were followed-up for 161 (interquartile range 123-202) days. Mean age was 68 (standard deviation 13) years and 68% were male. Referrals to the established telehealth program did not differ during (24%) and pre-COVID-19 (23%). Although all 10 centre-based services surveyed adopted telehealth, attendance (46.6% vs 59.9%; p<0.001) and completion (42.4% vs 75.4%; p<0.001) was significantly lower during COVID-19. Referral during vs pre-COVID-19 (sub hazard ratio [SHR] 0.77; 95% CI 0.68-0.87), and to a centre-based program compared to the established telehealth service (SHR 0.66; 95% CI 0.58-0.76) decreased the likelihood of CR uptake., Discussion: An established telehealth service and rapid adoption of telehealth by centre-based programs enabled access to CR in regional and rural Australia during COVID-19. However, further development of the newly implemented telehealth models is needed to promote CR attendance and completion., (Crown Copyright © 2022. Published by Elsevier B.V. All rights reserved.)
