“…Potentially, due to lacking prospective studies, higher vertical loading rates may be the result, rather than the cause, of several running injuries. Furthermore, internal tissue loads are greater than the loads predicted by the external forces because of the unaccounted contribution of the muscle forces 41,42 . However, it is possible that reducing the running impact loading was accompanied by secondary changes that affect muscular loading during midstance and eventually could respond to various running‐related injuries.…”

The first proof of this hypothesis came from a randomized controlled trial that reported a reduction in running-related injuries following an impact-reducing gait retraining program.…”

Purpose The present study aimed to determine whether runners can reduce impact measures after a six‐session in‐the‐field gait retraining program with real‐time musical biofeedback on axial peak tibial acceleration (PTAa) and identify the associated biomechanical adaptations. Methods Twenty trained high‐impact runners were assigned to either the biofeedback or the music‐only condition. The biofeedback group received real‐time feedback on the PTAa during the gait retraining program, whereas the music‐only condition received a sham treatment. Three‐dimensional gait analysis was conducted in the laboratory before (PRE) and within one week after completing the gait retraining program (POST). Subjects were instructed to replicate the running style from the last gait retraining session without receiving feedback while running overground at a constant speed of 2.9 m∙s−1. Results Only the biofeedback group showed significant reductions in both PTAa (∆x̅ = −26.9%, p = 0.006) and vertical instantaneous loading rate (∆x̅ = −29.2%, p = 0.003) from PRE to POST. In terms of biomechanical adaptations, two strategies were identified. Two subjects transitioned toward a more forefoot strike. The remaining eight subjects used a pronounced rearfoot strike and posteriorly inclined shank at initial contact combined with less knee extension at toe‐off while reducing vertical excursion of the center of mass. Conclusions After completing a music‐based biofeedback gait retraining program, runners can reduce impact while running overground in a laboratory. We identified two distinct self‐selected strategies used by the participants to achieve reductions in impact.

“…Modifications in spatiotemporal parameters, such as reduced CT including increased step frequency to 180 steps per minute, have recently been associated with 8.7% lower oxygen consumption [67] in well-trained adult female athletes and decreased risk of running-related injuries [16][17][18][19]. The increase in step frequency is one of the most used running retraining strategies from a clinical point of view because its increase above the preferred cadence at a constant speed generates a proportional shortening of the step length [68].…”

“…Among the spatiotemporal parameters most related to running economy are the contact time (CT), vertical oscillation (VO), step frequency and stride angle [12,15]. Some of these variables have also been associated with the prevalence of running-related injuries [16][17][18][19] together with growth-related factors, such as maturity offset and, more specifically in female athletes, the interrelationship of energy availability, menstrual function, and bone mineral density defined as the Female Athlete Triad [20,21]. The relationship between maturity offset and running biomechanics has been widely reported in sprint [22][23][24][25] and, more sparingly, in the distance running [26].…”

The purpose of this cross-sectional study was to analyse the relationship of neuromuscular performance and spatiotemporal parameters in 18 adolescent distance athletes (age, 15.5 ± 1.1 years). Using the OptoGait system, the power, rhythm, reactive strength index, jump flying time, and jump height of the squat jump, countermovement jump, and eight maximal hoppings test (HT8max) and the contact time (CT), flying time (FT), step frequency, stride angle, and step length of running at different speeds were measured. Maturity offset was determined based on anthropometric variables. Analysis of variance (ANOVA) of repeated measurements showed a reduction in CT (p < 0.000) and an increase in step frequency, step length, and stride angle (p < 0.001), as the velocity increased. The HT8max test showed significant correlations with very large effect sizes between neuromuscular performance variables (reactive strength index, power, jump flying time, jump height, and rhythm) and both step frequency and step length. Multiple linear regression found this relationship after adjusting spatiotemporal parameters with neuromuscular performance variables. Some variables of neuromuscular performance, mainly in reactive tests, were the predictors of spatiotemporal parameters (CT, FT, stride angle, and VO). Rhythm and jump flying time in the HT8max test and power in the countermovement jump test are parameters that can predict variables associated with running biomechanics, such as VO, CT, FT, and stride angle.

“…PR is determined by the individual's reaction to risk associated with COVID-19 E X H I B I T 1 Conceptual research framework (Attema et al, 2021). Sensitivity to the pandemic is the level of deeper cognitions which can ignite mental stressors during COVID-19 (Warden et al, 2021). EP is determined by the degree to which an expatriate is able to achieve his or her assignment objectives successfully (Varma et al, 2020).…”

The COVID 19 pandemic has changed the way that global businesses function, and has been the driving force behind a reevaluation of the factors that influence expatriate performance. This study empirically examines the mediating effects of perceived risk and sensitivity in the relationship between self-initiated expatriates support mechanisms (perceived organizational support and host-country national support) and expatriate performance during the COVID-19 pandemic.The data from 114 expatriates working and residing in Malaysia between March 27 and May 14, 2020 was analyzed using structural equation modelling. The results from the study indicate that host country national support significantly influences expatriate performance indirectly through expatriate engagement, while perceived risk and sensitivity moderate the relationship between perceived organizational support and host country national support through expatriate engagement. The integration of factors that influence work performance during a pandemic, such as perceived risk and sensitivity, leads to a more concise view of expatriation. Organizations need to be more prepared in terms of risk induced scenarios, and propose suitable intervention programs to mitigate the potential negative outcomes due to a pandemic.
