“…YBT performance did not change as a consequence of mental fatigue or watching a documentary. Hachard et al (2020) 30 also assessed the effects of mental fatigue on balance control with a similar study design, but by using a more sensitive measuring instrument (ie, force plate). They also let participants perform a 90‐minute continuous cognitive task (AX‐continuous performance test) as an intervention and watch a 90‐documentary as a control task, whereas balance control was measured before and after these 90‐minute tasks.…”

“…Their results showed that both mental fatigue and watching a documentary impaired balance control in the three different quiet stance tasks. The authors mainly attributed their results to the deleterious effect of prolonged sitting rather than to impairments in cognitive or attentional resources 30 . For the YBT, one possible explanation might be that the sensitivity of the traditional YBT is insufficient to detect delicate changes in balance control.…”

Mental fatigue impairs clinician‐friendly balance test performance and brain activity

While mental fatigue (MF) increases the probability of losing balance, the underlying neural mechanisms remain to be studied. Balance is commonly represented by technical outcomes difficult to translate to clinical practice. Therefore, the aims of this study were to assess how MF affects clinician‐friendly balance tests and if MF interacts with brain activity during these tests. Twelve healthy recreational athletes (age = 23 ± 2 years) participated. MF was induced by a 90‐minute Stroop test, while the control task encompassed a time‐matched documentary. Two clinician‐friendly balance tests (ie, Y‐balance test [YBT], reactive balance test [RBT]) were performed before and after the 90‐minute tasks. Brain activity was measured using electroencephalography during YBT and RBT. MF significantly decreased RBT accuracy compared to pre‐MF and compared to post‐control. MF did not affect YBT performance and visuomotor reaction time on the RBT. During the YBT, MF significantly induced higher prefrontal cortex theta activity. Brain activity during the RBT remained unchanged post‐MF. MF impairs RBT performance, but no underlying brain activity changes were observed. In contrast, YBT performance did not change due to MF, but alterations in brain activity during YBT performance were in line with previous MF research.

“…Hachard and colleagues observed that unexpectedly, their control condition of watching a documentary had adverse effects on performance in subsequent balance control tests in young, healthy participants (Hachard, Noé, Ceyte, Trajin, & Paillard, 2020). The authors discuss that participants' reduced performance in balance control following the control condition could be due to a deleterious effect of prolonged sitting.…”

Motor imagery (MI) practice in combination with neurofeedback (NF) is a promising supplement to facilitate the acquisition of motor abilities and the recovery of impaired motor abilities following brain injuries. However, the ability to control MI NF is subject to a wide range of inter-individual variability. A substantial number of users experience difficulties in achieving good results, which compromises their chances to benefit from MI NF in a learning or rehabilitation context. It has been suggested that context factors, that is, factors outside the actual motor task, can explain individual differences in motor skill acquisition. Retrospective declarative interference and sleep have already been identified as critical factors for motor execution (ME) and MI based practice. Here, we investigate whether these findings generalize to MI NF practice.Three groups underwent three blocks of MI NF practice each on two subsequent days. In two of the groups, MI NF blocks were followed by either immediate or delayed declarative memory tasks. The control group performed only MI NF and no specific interference tasks. Two of the MI NF blocks were run on the first day of the experiment, the third in the morning of the second day. Significant within-block NF gains in mu and beta frequency event-related desynchronization (ERD) where evident for all groups. However, effects of sleep on MI NF ERD were not found. Data did also not indicate an impact of immediate or delayed declarative interference on MI NF ERD.Our results indicate that effects of sleep and declarative interference context on ME or MI practice cannot unconditionally be generalized to MI NF skill acquisition. The findings are discussed in the context of variable experimental task designs, inter-individual differences, and performance measures.

Anti-inflammatory agents such as long-chain ω-3 fatty acids have been recognized to improve disease-related fatigue. We hypothesized that α-linolenic acid may also benefit in reduction of fatigue in low-grade inflammation such as overweight/obesity. Seventy two healthy children and adolescents with body mass index (BMI) >25 kg/m2 were randomized to flaxseed (n=38) and puffed wheat (n=34) groups. Participants consumed isocaloric amounts of either 20 g/day flaxseed or 25 g/day puffed wheat for 4 weeks. Fatigue, mood feelings (depression, anxiety, and stress), appetite, energy intake, weight, height, and waist circumference were measured. Analysis was performed based on per-protocol (PP) and intention-to-treat (ITT) approaches. Consumption of flaxseed decreased mental fatigue and caused a significant between-group difference (P<0.001). Although no significant change in physical and total score of fatigue was observed in either group, a significant between-group difference occurred due to a more remarkable change in these parameters in flaxseed group. General fatigue, motivation, activity, and mood feelings did not change significantly between groups. Flaxseed showed less benefit than puffed wheat on anthropometric measures as it caused smaller increase in height (0.53±0.89 vs. 1.09±0.87, P=0.03) and reduction in BMI (-0.25±0.63 vs. -0.67±0.56, P=0.01) than puffed wheat. Appetite and waist circumference decreased in both groups but no significant difference was observed between groups. In ITT analysis, only alteration in mental fatigue was significant. In conclusion, consumption of flaxseed may improve mental fatigue in children with overweight/obesity. However, because of smaller increase in height it is better to hinder administration of flaxseed in growth ages.
