“…These results were not consistent with those of Sinclair`s research, which stated that the force applied on Achilles tendon in running with barefoot is less than that of the 5-toed shoes [3]. The likely reason can be that the greater electromyographic activity of muscles in dynamic movements does not show the greater force produced by muscles [19] and the relationship of muscle activity domain with the produced force is linear only in isometric contraction [20,21].…”

Purpose:The current study aimed at evaluating the effect of 5-toed shoes on electromyographic activity of leg muscles during the stance phase of running. Methods:The current semi-experimental study recorded the electromyographic activity of tibialis anterior, soleus, gastrocnemius lateralis, and medialis muscles of 15 healthy male students (mean age: 24.5±3.4 years, mean height: 177.6±5.8 cm, and mean weight: 75.7±8.9 kg) during the stance phase of running in barefoot and shod (5-toed shoes) conditions. Paired sample t test was used for statistical analysis with SPSS19. Results:In shod running, electromyographic activity of tibialis anterior during loading response phase (P=0.001) and electromyographic activity of soleus (P=0.002) and medial gastrocnemius (P=0.004) during propulsion phase were significantly higher, compared with the barefoot running; there was no significant difference in gastrocnemius lateralis muscle between both conditions (P˃0.05). Conclusion:According to the current study findings, using 5-toed shoes could increase electromyographic activity of leg muscles during the stance phase of running.

“…Angular kinematics of the knee joint were calculated using an XYZ (sagittal, coronal and transverse) sequence of rotations. To quantify knee joint moments segment mass, segment length, GRF and angular kinematics were utilized using the procedure previously described by Sinclair (2014). The net joint moments were normalized by dividing by body mass (Nm/kg).…”

ObjectiveTo investigate the effects of a prophylactic knee brace on knee joint kinetics and kinematics in netball specific movements. DesignRepeated measures; Setting: Laboratory; Participants: Twenty university first team level female netball players. Outcome measurementsParticipants performed three movements, run, cut and vertical jump under two conditions (brace and no-brace). 3-D knee joint kinetics and kinematics were measured using an eight-camera motion analysis system. Knee joint kinetics and kinematics were examined using 2 × 3 repeated measures ANOVA whilst the subjective ratings of comfort and stability were investigated using chi-squared tests. ResultsThe results showed no differences (p > 0.05) in knee joint kinetics. However the internal/external rotation range of motion was significantly (p < 0.05) reduced when wearing the brace in all movements. The subjective ratings of stability revealed that netballers felt that the knee brace improved knee stability in all movements. ConclusionsFurther study is required to determine whether reductions in transverse plane knee range of motion serve to attenuate the risk from injury in netballers.

ImportanceIt has been demonstrated that total physical activity is not associated with risk of osteoarthritis. However, the association of different types of physical activity with incident knee osteoarthritis remains unclear.ObjectiveTo determine whether weight-bearing recreational physical activities are associated with increased risk of incident knee osteoarthritis.Design, Setting, and ParticipantsThis prospective cohort study used data from the Rotterdam Study (1996 to 2009), including participants with knee x-ray measurements at baseline and follow-up examinations. Participants with knee osteoarthritis at baseline were excluded. Residents aged 45 years and older of the Ommoord district in the city of Rotterdam in The Netherlands were invited to join the Rotterdam Study (78% response rate). Analysis was conducted in June 2023.ExposureTotal, weight-bearing, and non–weight-bearing recreational physical activities collected by questionnaires at baseline.Main Outcomes and MeasuresIncident radiographic knee osteoarthritis measured by knee x-ray was the primary outcome, and incident symptomatic knee osteoarthritis defined by x-ray and knee pain questionnaire was the secondary outcome. The association of different types of recreational physical activity with radiographic knee osteoarthritis was examined using logistic regression within generalized estimating equation framework after adjusting for potential confounders. A prespecified stratification analysis was planned on the basis of lower-limb muscle mass index (LMI) tertiles, measured by dual-energy x-ray absorptiometry.ResultsA total of 5003 individuals (2804 women [56.0%]; mean [SD] age, 64.5 [7.9] years) were included. The knee osteoarthritis incident rate was 8.4% (793 of 9483 knees) for a mean (SD) follow-up time of 6.33 (2.46) years. Higher weight-bearing activity was associated with increased odds of incident knee osteoarthritis (odds ratio [OR], 1.22; 95% CI, 1.10-1.35; P &lt; .001), but non–weight-bearing activity was not (OR, 1.04; 95% CI, 0.95-1.15; P = .37). In the analysis stratified by LMI tertiles, the association of weight-bearing activity with incident osteoarthritis was found only among 431 patients in the lowest LMI tertile (OR, 1.53; 95% CI, 1.15-2.04; P = .003), but not among patients in the middle or high LMI tertile.Conclusions and RelevanceThe findings of this study suggest that weight-bearing activity is associated with incident knee osteoarthritis in people with low levels of lower-limb muscle mass, which might be a promising avenue for tailored advice for physical activity.
