PET effects on physical fitness in  healthy workers  are moderated by age ( CRF ) and occupation type ( muscular endurance ) .
Further , independently computed subgroup analyses indicated that the training period of the PET programs may play an important role in improving CRF in workers
There is evidence that physical exercise training ( PET ) conducted at the workplace is effective in improving physical fitness and thus health .
However , there is no current systematic review available that provides high-level evidence regarding the effects of PET on physical fitness in the workforce .

Intelligent Physical Exercise Training in a Workplace Setting Improves Muscle Strength and Musculoskeletal Pain: A Randomized Controlled Trial
Purpose To assess effects of 1-year Intelligent Physical Exercise Training ( IPET ) on  musculoskeletal health . Methods Office workers were r and omized 1 : 1 to a training group , TG ( N = 193 ) , or a control group , CG ( N = 194 ) . TG received 1 h supervised high intensity IPET every week within working hours for 1 year and was recommended to perform 30 min of moderate intensity physical activity for 6 days a week during leisure . The IPET program was based on baseline health measures . Results No baseline differences were present . An intention-to-treat analysis showed significant between-group effect for muscle strength but not for musculoskeletal pain . However , a per- protocol analysis of those with an adherence of ≥70 % demonstrated a significant between-group effect for neck pain during the past three months . Several significant within-group changes were present , where TG and TG ≥ 70 % demonstrated clinical ly relevant pain reductions whereas minimal reductions were seen for CG . Conclusion IPET and recommendations of moderate intensity physical activity demonstrated significant between-group effect on muscle strength . Interestingly , significant within-group reductions in musculoskeletal pain were seen not only in TG but also in CG . This may underlie the lack of such between-group effect and shows that a possible positive side effect of merely drawing attention can improve musculoskeletal health
