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 .

Implementing intelligent physical exercise training at the workplace: health effects among office workers—a randomized controlled trial
Purpose The aim was to assess 1-year cardiovascular health effects of Intelligent Physical Exercise Training , IPET . Methods Office workers from six companies were r and omized 1:1 to a  training group , TG ( N = 194 ) or a  control group  , CG ( N = 195 ) . 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 6 days a week during leisure . The training program was based on baseline health check measures of cardiorespiratory fitness ( CRF ) , body composition , blood pressure , blood profile , and musculoskeletal health . Results There were no baseline differences between groups . CRF assessed as VO2max in absolute values and relative to body weight was ( mean ± SD ) : 3.0 ± 0.8 l/min and 35.4 ± 10.9 ml/min/kg for females , 3.9 ± 1.0 l/min and 37.9 ± 11.79 ml/min/kg for males . Intention to treat analysis demonstrated a significant almost 5 % increase in VO2max in TG compared with CG . A per protocol analysis of those with an adherence of ≥70 % demonstrated a significant increase in CRF of more than 10 % compared with CG , and a significant reduction in systolic blood pressure ( −5.3 ± 13.7 mm Hg ) compared with CG . Conclusion High intensity IPET combined with the recommendations of moderate intensity physical activity demonstrated significant clinical relevant improvements in CRF and systolic blood pressure . This underlines the effectiveness of health promotion by implementing physical exercise training at the workplace
