Exercise at an onsite facility with or without direct exercise supervision improves health‐related physical fitness and exercise participation: An 8‐week randomised controlled trial with 15‐month follow‐up
ISSUE ADDRESSED Physical activity and exercise participation is limited by a perceived lack of time , poor access to facilities and low motivation . The aim was to assess whether providing an exercise program to be completed at the workplace with or without direct supervision was effective for promoting health-related physical fitness and exercise participation . METHODS Fifty university employees aged ( Mean ± SD ) 42.5 ± 11.1 years were prescribed a moderate- to vigorous-intensity aerobic and resistance exercise program to be completed at an onsite facility for 8 weeks . Participants were r and omly allocated to receive direct exercise supervision or not . Cardiorespiratory fitness ( V̇O2max ) and maximal muscular strength were assessed at baseline and 8 weeks . Self-report physical activity was assessed at baseline , 8 weeks and 15 months post-intervention . RESULTS Attendance or exercise session volume were not different between groups . Cardiorespiratory fitness ( Mean ± 95 % CI ) ; + 1.9 ± 0.7 mL·kg·min-1 ; P < .001 ) , relative knee flexion ( + 7.4 ± 3.5 Nm·kg-1 % ; P < .001 ) and extension ( + 7.4 ± 4.6 Nm·kg-1 % ; P < .01 ) strength increased , irrespective of intervention group . Self-reported vigorous-intensity physical activity increased over the intervention ( mean ± 95 % CI ; + 450 ± 222 MET·minutes per week ; P < .001 ) , but did not remain elevated at 15 months ( + 192 ± 276 MET·minutes per week ) . CONCLUSION Providing a workplace exercise facility to complete an individually-prescribed 8-week exercise program is sufficient to improve health-related physical fitness in the short-term independent to the level of supervision provided , but does not influence long-term participation . SO WHAT ? : Lower cost onsite exercise facility supervision is as effective at improving physical health and fitness as directly supervised exercise , however ongoing support may be required for sustained physical activity behaviour change
