“…Research has established that muscle fatigue can affect APA (Silva, Struber, Daniel, & Nougier, 2021); therefore, we propose exploring the neuromuscular adaptation related to APA to understand this modification fully. Finally, APA is a sensitive measure that shows various modifications even in injuries such as chronic low back pain in the older population (Garcez et al, 2021).…”

Usually, dual cognitive tasks require additional attention to maintain postural control during standing and walking. In certain pathologies or injuries, dual cognitive tasks, such as walking and speaking, can challenge the balance system, making certain gait deficiencies more apparent. The issue is identifying normal gait changes compared to gait impairments to understand better the impact cognitive tasks have on gait mechanics. Purpose: To identify changes in temporospatial gait parameters in healthy young adults while walking and performing a cognitive task. Methods: Thirty-four healthy young adults participated in this study. We collected gait parameters with six gyroscopes and accelerometers (distributed on all limbs and trunk) during the 7-meter walk test. Two trials were performed with just walking at a self-selected pace (single task). Then, the participant was asked to perform a cognitive task by counting backward by three from 100 while walking for 7m for two more trials (dual cognitive task). Results: Dual cognitive tasks provoked significant adaptations (p<.05) in gait parameters, such as increased double limb support time and stance phase with a reduction in single limb support time and swing phase. Increase the length of the walking cycle by decreasing the cadence and speed of walking speed. In addition, an increase in mediolateral postural sway, first-step initiation time, and trunk range of motion was observed. Conclusion: Dual cognitive tasks can cause normal alterations in the gait's dynamic component and variations in walking initiation. We recommend studying neuromuscular modification, such as changes in muscle activation, during dual cognitive tasks.Contribution/Originality: The paper's primary contribution is finding gait and postural adaptations to dual cognitive tasks in healthy young adults. Specifically, this study identified anticipatory postural adaptations that could be used as a foundation to assess and create treatment interventions in those with balance impairments.

“…Although several definitions of NMF have been proposed, it can be broadly defined as an exercise-induced reduction in (1) maximal voluntary force generation [6] and (2) the control of submaximal force production [7] by a single muscle or several muscle groups. In soccer, acute NMF has been shown to reduce kicking accuracy and increase the time required to perform a kicking task [8], in addition to increasing injury risk, particularly during periods of soccer fixture congestion [9]. Such congestion is characteristic of the modern soccer game, with players regularly, and for a large part of the calendar year, exposed to competitive match-play environments.…”

Changes in Body Mass and Movement Strategy Maintain Jump Height Immediately after Soccer Match

A countermovement jump (CMJ) performed on a force plate is commonly applied in soccer to quantify acute neuromuscular fatigue (NMF), which may manifest immediately following soccer match play. Jump height (JH) is the main outcome variable reported for this purpose; however, it is sensitive to alterations in movement strategy, which may act to mask JH and, therefore, mask any presence of NMF. Acute reductions in body mass (BM) during match play could also lead to the maintenance of JH, but this is yet to be explored. This study sought to explore soccer-match-induced alterations to JH, movement strategy, and BM to inform future variable selection for the study of acute NMF. Fourteen male English National League soccer players performed three CMJs on a dual-force plate system immediately before and after a competitive soccer match. Differences in jump height were non-significant and trivial (p = 0.924, g = 0.03) before and after soccer match play, but there was a large post-match decrease in BM (g = 1.66). Furthermore, moderate decreases in jump momentum (g = 0.56) and countermovement depth (g = 0.72) were noted. As JH was determined by the take-off velocity, reduced BM could have augmented it (less mass to accelerate); however, reduced countermovement depth seemingly counteracted this (less distance to attain velocity). It may, therefore, be beneficial to report these variables when monitoring acute NMF via the CMJ.

“…is may subsequently alter the optimal pelvic rhythm during movement and place additional stress on of the spinal structure, contributing to tissue damage and pain [12]. Published study reported that GA dysfunction increased the risk of back injury in sportspersons [12], and fatigue of the GA was associated with a reduction of APAs timing variability in healthy individuals [13]. Recent published meta-analysis indicated the role of distal lower limb muscles of the ankle and knee joints in low back pain remains unclear [2].…”

Objectives. To explore the relationship between postural control and pain-related clinical outcomes in patients with chronic nonspecific low back pain (cNLBP). Methods. Participants with cNLBP and healthy individuals were recruited. Muscle activities were recorded during internal and external perturbation tasks. Postural control capacity was assessed by muscle onset time and integrals of electromyography (iEMGs) of postural muscles during the phases of anticipatory postural adjustments (APAs) and compensatory postural adjustments (CPAs). Correlation analysis was employed to investigate the relationship between postural control capacity, pain, and disability. Results. Twenty-seven patients with cNLBP and 27 healthy participants were recruited. Gastrocnemius (GA) muscle onset time was earlier in the cNLBP group than in the control group in the internal perturbation task. The onset time of GA and erector spinae (ES) of the cNLBP group was later than that of the controls in the external perturbation task. Disability level moderately correlated with the iEMGs of rectus abdominis (RA), GA, and external oblique (EO) during APAs. Pain score moderately correlated with the iEMGs of RA, EO, and ES during CPAs of perturbation tasks. Conclusion. cNLBP participants had altered muscle activation strategy to maintain postural stability in response to perturbation. This study further discovered that pain-related disabilities of cNLBP participants were likely related to the APAs capacity, whereas the pain intensity may relate to the CPAs capacity. Pain and disability may therefore be related to the control process of the posture-related muscles.
