“…The magnitude of asymmetry varied across the variables investigated. Globally, kinetic variables showed more asymmetry than spatiotemporal variables (figure 1), which is consistent with previous work 5–7. In this study, only vertical impact peak and vertical loading rate exceeded 10%, while spatiotemporal variables were below 2%.…”

“…Consistently, sex was only identified as a determinant for two variables in this study. Running speed was only associated with lower asymmetry for flight time, which is consistent with previous work on within-subject effects, suggesting that asymmetry does not vary with speed 5 7 11. Thus, it seems that between-subject and within-subject variations in running speed have a limited impact on asymmetry.…”

“…Only two prospective studies have investigated interlimb asymmetry related to injury risk. In cross-country runners, there were no differences in asymmetry of kinematic and kinetic variables between runners who sustained an injury and those who remained healthy during follow-up 5. In novice runners, asymmetry in impact peak at baseline was lower in runners who sustained an injury during follow-up 11.…”

“…Symptomatic runners may alter their running mechanics and exacerbate lower limb asymmetry, which may, in turn, lead to mechanical overload and injury. Only two prospective studies have related gait asymmetry and injury risk 5 11. In cross-country runners followed over 12 weeks, there were no differences in asymmetry in kinematic, kinetic and spatiotemporal variables between injured runners and those that remained injury free, but the sample size was very small (n=22) 5.…”

ObjectiveTo investigate asymmetry in spatiotemporal and kinetic variables in 800+ recreational runners, identify determinants of asymmetry, investigate if asymmetry is related to greater running injury risk and compare spatiotemporal and kinetic variables between the involved and uninvolved limb at baseline in runners having sustained an injury during follow-up.Methods836 healthy recreational runners (38.6% women) were tested on an instrumented treadmill at their preferred running speed at baseline and followed up for 6 months. From ground reaction force recordings, spatiotemporal and kinetic variables were derived for each lower limb. The Symmetry Index was computed for each variable. Correlations and multiple regression analyses were performed to identify potential determinants of asymmetry. Cox regression analyses investigated the association between asymmetry and injury risk. Analysis of variance for repeated measures was used to compare the involved and uninvolved limbs in runners who had sustained injuries during follow-up.Results107 participants reported at least one running-related injury. Leg length discrepancy and fat mass were the most common determinants of asymmetry, but all correlation coefficients were negligible (0.01–0.13) and explained variance was very low (multivariable-adjusted R2<0.01–0.03). Greater asymmetry for flight time and peak breaking force was associated with lower injury risk (HR (95% CI): 0.80 (0.64 to 0.99) and 0.96 (0.93 to 0.98), respectively). No between-limb differences were observed in runners having sustained an injury.ConclusionGait asymmetry was not associated with higher injury risk for investigated spatiotemporal and kinetic variables.Trial registration numberNCT03115437.

Mechanical Asymmetries during Treadmill Running: Effects of Running Velocity and Hypoxic Exposure

et al. 2023

Studies evaluating mechanical asymmetry across a range of running velocities during treadmill runs have yielded inconsistent findings, while the impact of additional hypoxic exposure has never been investigated. The aim of this study was to characterize the effects of manipulating running velocity and hypoxic exposure on gait asymmetry during treadmill running. Eleven trained individuals performed seven runs at different velocities (8, 10, 12, 14, 16, 18, and 20 km·h−1) in a randomized order, each lasting 45 s. The running took place on an instrumented treadmill for normoxia (FiO2 = 20.9%), moderate hypoxia (FiO2 = 16.1%), high hypoxia (FiO2 = 14.1%), and severe hypoxia (FiO2 = 13.0%). Vertical and antero-posterior ground reaction force recordings over 20 consecutive steps (i.e., after running ∼25 s) allowed the measurement of running mechanics. Lower-limb asymmetry was assessed from the ‘symmetry angle’ (SA) score. Two-way repeated-measures ANOVA (seven velocities × four conditions) was used. There was no significant difference in SA scores for any of the biomechanical variables for velocity (except contact time and braking phase duration; p = 0.003 and p = 0.002, respectively), condition, or interaction. Mean SA scores varied between ∼1% and 2% for contact time (1.5 ± 0.8%), flight time (1.6 ± 0.6%), step length (0.8 ± 0.2%), peak vertical force (1.2 ± 0.5%), and mean vertical loading rate (2.1 ± 1.0%). Mean SA scores ranged from ∼2% to 5% for duration of braking (1.6 ± 0.7%) and push-off phases (1.9 ± 0.6%), as well as peak braking (5.0 ± 1.9%) and push-off forces (4.8 ± 1.7%). In conclusion, the trained runners exhibited relatively even strides, with mechanical asymmetries remaining low-to-moderate across a range of submaximal, constant running velocities (ranging from 8 to 20 km·h−1) and varying levels of hypoxia severity (between normoxia and severe hypoxia).
