    Abstract

    Reviews of workplace physical activity interventions indicate limited effects of these programs on employee health (1) and fitness (2). This randomised controlled trial compared the effectiveness of personal, non-personal and no-exercise supervision in the workplace to improve cardiorespiratory fitness (CRF), muscular strength and body composition. Eighty-five Australian university employees (62 female; mean±SD 43.2±9.8 years) were randomised to either personal (1:1; SUP, N=28) supervision, non-personal (typical gym-based; NPS, N=28) supervision or unsupervised control (CON, N=29) exercise groups. Participants received an individually tailored, moderate-to-high intensity aerobic and resistance exercise program to complete for 16 weeks at an onsite gymnasium (SUP and NPS) or without access to a specific exercise facility (CON). Changes to CRF (V̇O2 peak), muscular strength (1RM bench and leg press) and body composition (body fat % measured by dual-energy X-ray absorptiometry) were analysed using repeated measures ANOVA. Mean changes to CRF were greater (p<0.01) with SUP (+10.4±11.1%) compared to CON (+3.8±8.9%), but not different to NPS (+8.6±8.2%). When compared to CON (+1.7±7.7%), mean upper body strength changes were significantly greater with both SUP (+12.8±8.4%; p<0.001) and NPS (+8.4±7.3%; p<0.05). Mean lower body strength changes were greater with SUP (+26.3±12.7%) compared to both NPS (+15.0 ± 14.6%; p<0.05) and CON (+4.1 ± 12.4%; p<0.001), and NPS compared to CON (p<0.01). Mean reductions to body fat percentage were greater with SUP (-2.2±2.2%) compared to both NPS (-0.6±1.9%; p<0.05) and CON (-0.7±1.9%; p<0.05). Provision of an onsite exercise facility enables increased CRF over a 16-week intervention. Personal exercise supervision, in addition to an onsite exercise facility, produced greater improvements to muscular strength and body composition than simply providing an exercise facility and/or an individually tailored exercise program. To improve cardiometabolic health in a university workplace, employers should consider providing at least 16-weeks of supervised exercise training at an onsite facility.
