Physical activity and feelings of energy and fatigue: epidemiological evidence.
TLDR
There was agreement among the studies suggesting a strong, consistent, temporally appropriate dose-response relationship between physical activity and feelings of energy and fatigue, which is sufficiently strong to justify better controlled prospective cohort studies and randomised controlled trials.Abstract:
Approximately 20% of adults worldwide report persistent fatigue. Physical activity is a healthful behaviour that has promise for combating feelings of fatigue and low energy. This article summarises the epidemiological literature that examined the association between physical activity and feelings of energy and fatigue. Twelve population-based studies conducted between January 1945 and February 2005 that concurrently measured physical activity and feelings of energy and fatigue were located. All of the studies suggested that there was an association between physical activity and a reduced risk of experiencing feelings of low energy and fatigue when active adults were compared with sedentary peers (odds ratio = 0.61; 95% CI 0.52, 0.72). The effect was heterogeneous and varied according to study design and the energy/fatigue measure used in the study. Because epidemiological comparisons cannot establish direction of causality, standard criteria for evaluating strength of evidence in epidemiological studies (i.e. strength of association, temporal sequence, consistency, dose response and biological plausibility) were used to judge whether the observed association between physical activity and feelings of energy and fatigue suggest causality in the absence of adequate experimental evidence. There was agreement among the studies suggesting a strong, consistent, temporally appropriate dose-response relationship between physical activity and feelings of energy and fatigue. No compelling evidence has confirmed any plausible biological mechanisms that explain the apparent protective effect of physical activity against feelings of low energy and fatigue. Nonetheless, the epidemiological evidence is sufficiently strong to justify better controlled prospective cohort studies and randomised controlled trials.read more

The effect of acute aerobic exercise on positive activated affect: A meta-analysis
Justy Reed,Deniz S. Ones +1 more
TL;DR: In this paper, the authors examined the effect of acute aerobic exercise on self-reported positive-activated affect (PAA) in 158 studies from 1979 to 2005, yielding 450 independent effect sizes (ESs) and a sample size of 13,101.

Job burnout and depression : Unraveling their temporal relationship and considering the role of physical activity
Sharon Toker,Michal Biron +1 more
TL;DR: The current study unravels the temporal relationship between job burnout and depression and examines whether the job burn out-depression association may be contingent upon the degree to which employees engage in physical activity, finding that physical activity attenuated these effects in a dose-response manner.

TL;DR: If yoga dampens or limits both fatigue and inflammation, then regular practice could have substantial health benefits and chronic inflammation may fuel declines in physical function leading to frailty and disability.

Effects of chronic exercise on feelings of energy and fatigue: a quantitative synthesis
TL;DR: The authors investigate the effect of chronic exercise on feelings of energy and fatigue using meta-analytic techniques and highlight the need for research identifying the most useful control conditions for accurately interpreting mental health outcome data obtained in chronic exercise investigations.
