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 .
To quantify sex- , age- , and occupation type-specific effects of PET on physical fitness and to characterize dose – response relationships of PET modalities that could maximize gains in physical fitness in the working population .
The Effect of Intelligent Physical Exercise Training on Sickness Presenteeism and Absenteeism Among Office Workers
Objective : The aim of this study was to investigate the effect of individually tailored intelligent physical exercise training ( IPET ) on  presenteeism and absenteeism among office workers . Methods : In a 1-year r and omized controlled trial ( RCT ) , employees were allocated to a training group TG ( N = 193 ) or control group CG ( N = 194 ) . TG received 1-hour high-intensity IPET once a week within working hours , and was recommended to perform 30 minutes of moderate-intensity physical activity ( PA ) 6 days a week during leisure-time . Results : An intention-to-treat analysis showed no effect on absenteeism , but a significant 4 % increase in workability and 9 % increase in general health in TG compared with CG . A per- protocol analysis [ adherence of ≥70 % ( N = 89 ) ] in addition showed a significant 6 % increase in productivity and a 29 % reduction in absenteeism compared with CG . Conclusion : IPET combined with recommendations of leisure-time PA significantly improved presenteeism and decreased absenteeism if following the protocol
