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 .

Effects on muscle strength, maximal jump height, flexibility and postural sway after soccer and Zumba exercise among female hospital employees: a 9-month randomised controlled trial
ABSTRACT This 9-month r and omised controlled workplace physical activity trial investigated the effects of soccer and Zumba exercise , respectively , on muscle strength , maximal jump height , sit- and -reach flexibility and postural sway among female workers . A total of 107 female hospital employees aged 25–63 were cluster-r and omised  to a soccer group , a Zumba group or a control group .  Training was conducted outside working hours as two to three 1-h weekly sessions the first 3 months and once a week the last 6 months . Tests were conducted at baseline , after 3 and 9 months . The soccer group improved maximal neck extension strength both after 3 ( 1.2 kg ; P < 0.05 ) and 9 months ( 1.7 kg ; P < 0.01 ) compared to the control group . The Zumba group improved maximal trunk extension strength ( 3.1 kg ; P = 0.04 ) after 3 months , with improvements in postural sway velocity moment ( −9.2 mm2/s ; P < 0.05 ) and lower limb lean mass ( 0.4 kg ; P < 0.05 ) after 9 months . No significant intervention effects were revealed in vertical jump height or sit- and -reach flexibility . The present study indicates that workplace-initiated soccer and Zumba exercise may be beneficial for improvement of the neck and trunk strength , which may have preventive effects with regard to future perceived muscle pain in the respective body regions . Furthermore , the Zumba group revealed positive effects on lower limb lean mass and postural sway compared to the control group
