The effect of ego depletion or mental fatigue on subsequent physical endurance performance: A meta-analysis

Abstract

Highlights-Ego depletion and mental fatigue impair subsequent endurance performance-The duration of the mental effort task doesn't predict the magnitude of impairment-The effect is higher on isolation than whole-body tasks-The effect is higher when the person-situation fit is low-This effect should not be seen only through the "fatigue" prism but also as "value"

Mental fatigue might be not so bad for exercise performance after all: a systematic review and bias-sensitive meta-analysis.

“…These conclusions seem to stand in contrast with those of two previous meta-analyses conducted in this domain Giboin & Wolff, 2019). performed a meta-analysis based on a similar literature search strategy, except for the fact that their inclusion criteria also considered tasks shorter than 30 mins.…”

“…In general, the reported effect sizes seem to become closer to zero over the years. This trend is significant in the dataset analyzed by , b1 = -0.04, SEb = 0.01, z = -3.11, p = .002, and non-significant for Giboin and Wolff, b1 = -4 Some peculiarities of the meta-analyses conducted by and Giboin and Wolff (2019) prevent the use of the 3-parameter selection model to test for publication bias. Both meta-analyses collated data from studies with within-participants designs and between-groups designs.…”

“…Funnel plot asymmetry is not the only piece of evidence suggesting that publication bias might be affecting this literature. 4 In Figure 4B, we plot the effect sizes meta-analyzed by and Giboin and Wolff (2019) against their year of publication. In general, the reported effect sizes seem to become closer to zero over the years.…”

“…And second, most studies on this topic are based on small samples (mean N = 12), which renders them underpowered to detect small but non-trivial effect sizes. In view of these limitations, the purpose of the present meta-analysis is to shed light on whether there is a detectable negative effect of mental fatigue (induced by long and demanding cognitive tasking) on exercise performance, qualifying the other two recent meta-analyses on this topic Giboin & Wolff, 2019).…”

Bored into depletion? Towards a tentative integration of perceived self-control exertion and boredom as guiding signals for goal-directed behavior

“…A substantial body of evidence supports the ego depletion concept (Cunningham & Baumeister, 2016). On the behavioral level, a multitude of studies has shown that ego depletion leads to impaired performance in a broad range of subsequent self-control demanding tasks (for meta-analyses, please see Giboin & Wolff, 2019;Hagger et al, 2010). On the experiential level, applying self-control leads to perceptions of exertion (Milyavskaya, Inzlicht, Johnson, & Larson, 2019;Wolff et al, 2019), thereby attesting to the implied costliness of exerting self-control (Baumeister et al, 1998).…”
