“…The results of this study indicated that, following both anaerobic and aerobic exercise protocols, there was a significant reduction in the participants’ Posturography Assessment, SI scores, low sway frequencies (visual input), medium-low frequencies (vestibular input), and medium–high sway frequencies (somatosensory input). This pre-to post-fatigue reduction is in line with the findings of several previous studies (Kozinc et al, 2021; Lyu et al, 2021; Steinberg et al, 2016a, 2016b), whereby both anaerobic and aerobic protocols caused a balance impairment due to fatigue (Chaubet et al, 2012). Although previous investigators suggested that this decreased stability was related to reductions in the combined quality of information provided by the visual, vestibular, and proprioceptive systems (Lepers et al, 1997), few prior researchers examined the pattern of deterioration of each system individually (Steinberg et al, 2022; Yin et al, 2020; Zemkova & Hamar, 2014).…”

“…It should, however, be noted that in their study, Lyu et al (Lyu et al, 2021) used the medium-frequency band to reflect the contribution of both inputs, without differentiating between the vestibular and the somatosensory inputs (unlike the Tetrax device used in the current study). As for the improved active somatosensory ability, this improvement may be attributable to increased arousal, elicited by the physical activity (rather that an outcome of fatigue).…”

“…The profound stimulation of muscle spindles, tendon organs, joint receptors, and cutaneous mechanoreceptors may lead to their impaired sensitivity, then causing this deteriorated proprioceptive feedback or control of balance and contributing to greater sway velocity after running (Zemkova & Hamar, 2014). In addition, Lyu et al (Lyu et al, 2021) found increased vestibular and somatosensory activity with decreased visual input following fatigue, suggesting an adaptation effect in the sensory system due to increased vestibular/somatosensory activity. Such an effect might be due to the increased activation of the sympathetic nervous system (i.e., increased arousal of the systems), that may compensate for the loss of visual contribution during fatigue exercises.…”

Fatigue can impair function of the three sensory systems (vestibular, visual, and somatosensory) that control postural balance. Yet impairment may be greater among individuals with than those without chronic ankle instability (CAI). The present study used posturography assessment to extend previous findings demonstrating reduced function of the three systems in CAI participants following fatigue. Our aim in this study was to examine the influence of anaerobic and aerobic protocols on the function of these three sensory systems in individuals with and without CAI. We assessed 60 healthy physical education students ( Mage = 24.3, SD = 3.4) by a Tetrax® Posturography device for Stability-Index and Fourier-frequencies [ low sway (F1) visual input, medium-low sway (F2–F4) vestibular input, medium–high sway (F5–F6) somatosensory input] and by the Active Movement Extent Discrimination Assessment (AMEDA) for active ankle somatosensory ability, before and after performing anaerobic or aerobic protocols. Among participants, 45% were identified with CAI. We found significant Time effect (pre-post), CAI effect, and CAI X Time interactions for Fourier frequencies, Stability-Index, and AMEDA scores, indicating greater pre-post deterioration for those with CAI compared to those without CAI ( p < .05). CI (95%) showed that, although there was a Time effect for F1, F2–F4, and F5–F6, only F5–F6 frequencies (i.e., somatosensory input) showed the CAI effect and the Time X CAI interaction. Thus, participants with and without CAI showed reduced visual, vestibular, and somatosensory ability following fatigue. While we found greater deterioration in both passive and active somatosensory ability (F5-6 and AMEDA) among individuals with CAI compared with those with no-CAI, we recommend intervention programs for improving vestibular abilities following fatigue in both those with and without CAI.

“…Similar to our results, Ratka and colleagues (Ratka et al, 2020), reported a significant increase in NPC values in the presence of exertional fatigue among physically active participants. Furthermore, Lyu et al (2021) reported that visual system function was affected following strenuous exercise, and Connell et al (2016) found impairment eye movement control after strenuous exercise. Derave et al (2002) showed that post-fatigue values were significantly higher than pre-values in an eyes-open but not in an eyes-closed condition.…”

The Function of the Proprioceptive, Vestibular and Visual Systems Following Fatigue in Individuals With and Without Chronic Ankle Instability

To maintain postural balance, the proprioceptive, vestibular, and visual systems continuously provide body position and movement data to the central nervous system. In this study, our main aim was to examine, for the first time, the influence of anaerobically or aerobically induced fatigue on these separate functions in persons with and without chronic ankle instability (CAI). We obtained assessments pre- and post-fatigue protocols from 60 physical education students ( Mage = 24.3, SD = 3.4) Twenty-seven students had CAI, and 33 students did not have CAI). To measure proprioception, we used the AMEDA device; for vision, we used near point of convergence (NPC); and, for vestibular function, we used subjective visual vertical (SVV). We found a pre-post proprioception (AMEDA) effect in the aerobic group ( p < .001), and a visual (NPC) effect in both anaerobic and aerobic participant groups (both p < .001). There were no visual system (NPC) fatigue effect differences among aerobic or anerobic participants who had or did not have CAI ( p = .047); there was a significant aerobic fatigue effect on proprioception (AMEDA) ( p = .010) that favored participants without CAI. There was a significant interaction effect between time of testing and CAI for visual (NPC) ( p = .003) in the aerobic group only. In both the anaerobic and aerobic groups, post-fatigue vestibular function (AMEDA) was significantly lower for those with than those without CAI (anaerobic: p = .030; and aerobic: p =.016). Thus, post-fatigue, participants with CAI showed worse proprioceptive, visual, and vestibular function than those without CAI. Future investigators should further examine each movement sense system in individuals with CAI.

“…On the other hand, some authors have reported no significant changes in postural sway variables after exercise. A recent study by Lyu et al (2021) evidenced a general compensation in the central nervous system in response to the neuromuscular deficiencies induced by local fatiguing exercise and put forward the function of sensory recalibration in maintaining postural stability under fatigue conditions. For instance, repeated measurements for up to 10 min after a fatiguing calf-muscle exercise showed no increase of body sway, which indicates that postural control in quiet standing can be maintained by compensatory mechanisms activated during muscle fatigue ( Adlerton and Moritz, 1996 ).…”

While the effect of a variety of exercises on postural balance control has been extensively studied, less attention has been paid to those requiring sport-specific skills. Therefore there is a need to analyze the literature and elucidate changes in postural balance control after exercises performed in conditions close to a particular sport. This scoping review aims (i) To map the literature that addresses postural sway aspects of acute responses to general and sport-specific exercises and their underlying physiological mechanisms, and (ii) To identify gaps in the existing literature and propose future research on this topic. The main literature search conducted on MEDLINE, Web of Science, Scopus, PubMed, and Cochrane Library databases was completed by SpringerLink, Elsevier, and Google Scholar. A total of 60 articles met the inclusion criteria. Findings identified that among a variety of studies evaluating the effects of exercise on postural balance control, only few of them were conducted under sport-specific conditions (i.e., while shooting in biathlon or pentathlon, and after simulated or match-induced protocols in combat and team sports). Therefore, more research is still needed to address this gap in the literature and aim research at investigation of postural sway response to sport-specific exercises. Further analysis of the literature showed that the type, intensity and duration of exercise play a key role in increased postural sway. Whole body and localized muscular fatigue of the trunk, neck and lower limbs is considered to be a main factor responsible for the magnitude of balance impairment in an initial phase of recovery and speed of its readjustment to a pre-exercise level. Other likely factors affecting postural stability are hyperventilation and deterioration of sensorimotor functions, though some contribution of muscle damage, dehydration, hyperthermia or dizziness cannot be excluded. A better understanding of the physiological mechanisms of balance impairment after exercises performed under simulated fatigue induced protocol, close to conditions specific to a particular sport, has implications for designing smart exercise programs tailored to individual needs to improve athlete performance with high demands on postural stability and/or decrease their risk of injuries.
