It can be concluded that physical activity may be effective in reducing burn-out risk .
The few observational studies linking sedentary and dietary behavior with burn-out risk suggest that being more sedentary and eating less healthy are each associated with higher burn-out risk .
Although it is believed that physical activity , sedentary , and dietary behavior ( i.e. , energy balance-related behavior ) may decrease the risk of burn-out  , the association between both is currently not well understood .
Therefore , the aim of this systematic review was to synthesize studies investigating the relationship between energy balance-related behavior  and  burn-out risk .
Exercise to reduce work-related fatigue among employees: a randomized controlled trial.
Objectives The present study evaluated the efficacy of an exercise intervention to reduce work-related fatigue ( emotional exhaustion , overall fatigue , and need for recovery ) . The effects of exercise on self-efficacy , sleep , work ability , cognitive functioning and aerobic fitness ( secondary outcomes ) were also investigated . Methods Employees with high levels of work-related fatigue were r and omly assigned to either a 6-week exercise intervention  ( EI ; N=49 ) or a wait-list control group ( WLC  ; N=47 ) . All participants were measured pre- ( T0 ) and post-intervention ( T1 ) . EI participants were also measured 6 ( T2 ) and 12 weeks ( T3 ) after the end of the intervention . Analyses were based on intention-to-treat ( ITT ) and per- protocol ( PP ) . PP analyses only included EI participants ( N=31 ) who completed the intervention and WLC participants ( N= 35 ) who did not increase their exercise level during the wait period . Results Analyses of covariance ( ANCOVA ) revealed that , at T1 , the EI group reported lower emotional exhaustion and overall fatigue than the WLC group , however , only according to PP analyses . Both according to ITT and PP analyses , EI participants showed higher sleep quality , work ability , and self-reported cognitive functioning at T1 compared to WLC participants . Intervention effects were maintained at T2 and T3 . Conclusions The exercise intervention had enduring effects on work-related fatigue and broader indicators of employee well-being . This study demonstrates that , in case of work-related fatigue , exercise does constitute a powerful medicine for those who comply with the treatment
