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 .
The effect of experimentally induced sedentariness on mood and psychobiological responses to mental stress
Background Evidence suggests a link between sedentary behaviours and depressive symptoms . Mechanisms underlying this relationship are not understood , but inflammatory processes may be involved . Autonomic and inflammatory responses to stress may be heightened in sedentary individuals contributing to risk , but no study has experimentally investigated this . Aims To examine the effect of sedentary time on mood and stress responses using an experimental design . Method Forty-three individuals were assigned to a free-living sedentary condition  and to  a control condition ( usual activity ) in a cross-over , r and omised fashion and were tested in a psychophysiology laboratory after spending 2 weeks in each condition . Participants completed mood question naires ( General Health Question naire and Profile of Mood States ) and wore a motion sensor for 4 weeks . Results Sedentary time increased by an average of 32 min/day ( P = 0.01 ) during the experimental condition compared with control . Being sedentary result ed in increases in negative mood independent of changes in moderate to vigorous physical activity ( ΔGHQ = 6.23 , ΔPOMS = 2.80 ) . Mood disturbances were associated with greater stress-induced inflammatory interleukin-6 ( IL-6 ) responses ( β = 0.37 ) . Conclusions Two weeks of exposure to greater free-living sedentary time result ed in mood disturbances independent of reduction in physical activity . Stress-induced IL-6 responses were associated with changes in mood
