“…These results are in agreement with the findings reported by previous studies [17,21,46] which found that the hip and knee flexion and ankle dorsiflexion ROMs individually determined a meaningful proportion of the explained variance ( R 2 ) for the y-balance test (ranging from 5 to 30% of the composite score) in different cohorts of athletes. These findings may support the hypothesis that those athletes with limited hip and knee flexion and ankle dorsiflexion ROMs might show a sub-optimal dynamic postural control while performing explosive actions (i.e., kicking and changes of direction) due to a smaller anterior displacement of their center of mass, which may increase the likelihood of losing stability.…”

“…ROM). This hypothesis seems to be supported by the results reported in the current study, in which the scores obtained by the male futsal players in the core stability tasks were similar or even slightly better to those reported by López-Valenciano et al [17] for the female players, and both BNs also selected some of these measures as independent predictors for the dynamic postural control performance.…”

“…In particular, this study found that the measure of core stability recorded while players were performing medial-lateral displacements on an unstable seat explained a large percentage (31.1%) of the performance achieved in the composite score of the y-balance test in female, but not in male professional football players. These sex-related differences found by López-Valenciano et al [17] in the identification of this variable as an independent predictor for the y-balance test performance, but not in the absolute distances reached (composite scores), may be partially attributed to the fact that female players reported better results (statistically significant) in the core stability measures (with the exception of the static stability measure with feedback [CS-WF]) in comparison with their counterpart male football players (e.g. : CS-NF: 6.1 mm [males]– 4.3 mm [females], CS-CD: 10.8 mm [males]– 9.2 mm [females]).…”

“…Although core stability has been proposed as a crucial factor for y-balance test [47], only López-Valenciano et al [17] have confirmed this link in professional female football players. In particular, this study found that the measure of core stability recorded while players were performing medial-lateral displacements on an unstable seat explained a large percentage (31.1%) of the performance achieved in the composite score of the y-balance test in female, but not in male professional football players.…”

“…Potentially, the execution of this test might require, among others, adequate levels of hip and knee strength, power, trunk or core stability, coordination and lower extremity ranges of motion (ROM). With the aim of improving the design of training interventions, some studies have explored the individual contribution of certain measures of knee strength [15–17], hip strength [17–19], lower extremity power [20], core stability [17] and lower extremity ROMs [17,21] on y-balance test performance using linear regression models in different cohorts of athletes. However, these studies have reported conflicting results that might not permit clinicians, physiotherapists and physical trainers to make general training recommendations.…”

Purpose The purpose of this study was to analyse the relationship between several parameters of neuromuscular performance with dynamic postural control using a Bayesian Network Classifiers (BN) based analysis. Methods The y-balance test (measure of dynamic postural control), isokinetic (concentric and eccentric) knee flexion and extension strength, isometric hip abduction and adduction strength, lower extremity joint range of motion (ROM) and core stability were assessed in 44 elite male futsal players. A feature selection process was carried out before building a BN (using the Tabu search algorithm) for each leg. The BN models built were used to make belief updating processes to study the individual and concurrent contributions of the selected parameters of neuromuscular performance on dynamic postural control. Results The BNs generated using the selected features by the algorithms correlation attribute evaluator and chi squared reported the highest evaluation criteria (area under the receiver operating characteristic curve [AUC]) for the dominant (AUC = 0.899) and non-dominant (AUC = 0.879) legs, respectively. Conclusions The BNs demonstrated that performance achieved in the y-balance test appears to be widely influenced by hip and knee flexion and ankle dorsiflexion ROM measures in the sagittal plane, as well as by measures of static but mainly dynamic core stability in the frontal plane. Therefore, training interventions aimed at improving or maintaining dynamic postural control in elite male futsal players should include, among other things, exercises that produce ROM scores equal or higher than 127° of hip flexion, 132.5° of knee flexion as well as 34° and 30.5° of ankle dorsiflexion with the knee flexed and extended, respectively. Likewise, these training interventions should also include exercises to maintain or improve both the static and dynamic (medial-lateral plane) core stability so that futsal players can achieve medial radial error values lower than 6.69 and 8.79 mm, respectively.

Background‘Mitochondrial Myopathy’ (MM) refers to genetically‐confirmed Primary Mitochondrial Disease (PMD) that predominantly impairs skeletal muscle function. Validated outcome measures encompassing core MM domains of muscle weakness, muscle fatigue, imbalance, impaired dexterity, and exercise intolerance do not exist. The goal of this study was to validate clinically‐meaningful, quantitative outcome measures specific to MM.MethodsThis was a single centre study. Objective measures evaluated included hand‐held dynamometry, balance assessments, Nine Hole Peg Test (9HPT), Functional Dexterity Test (FDT), 30 second Sit to Stand (30s STS), and 6‐minute walk test (6MWT). Results were assessed as z‐scores, with < −2 standard deviations considered abnormal. Performance relative to the North Star Ambulatory Assessment (NSAA) of functional mobility was assessed by Pearson's correlation.ResultsIn genetically‐confirmed MM participants [n = 59, mean age 21.6 ± 13.9 (range 7 – 64.6 years), 44.1% male], with nuclear gene aetiologies, n = 18/59, or mitochondrial (mtDNA) aetiologies, n = 41/59, dynamometry measurements demonstrated both proximal [dominant elbow flexion (−2.6 ± 2.1, mean z‐score ± standard deviation, SD), hip flexion (−2.5 ± 2.3), and knee flexion (−2.8 ± 1.3)] and distal muscle weakness [wrist extension (−3.4 ± 1.7), palmar pinch (−2.5 ± 2.8), and ankle dorsiflexion (−2.4 ± 2.5)]. Balance [Tandem Stance (TS) Eyes Open (−3.2 ± 8.8, n = 53) and TS Eyes Closed (−2.6 ± 2.7, n = 52)] and dexterity [FDT (−5.9 ± 6.0, n = 44) and 9HPT (−8.3 ± 11.2, n = 53)] assessments also revealed impairment. Exercise intolerance was confirmed by strength‐based 30s STS test (−2.0 ± 0.8, n = 38) and mobility‐based 6MWT mean z‐score (−2.9 ± 1.3, n = 46) with significant decline in minute distances (slope −0.9, p = 0.03, n = 46). Muscle fatigue was quantified by dynamometry repetitions with strength decrement noted between first and sixth repetitions at dominant elbow flexors (−14.7 ± 2.2%, mean ± standard error, SEM, n = 21). All assessments were incorporated in the MM‐Composite Assessment Tool (MM‐COAST). MM‐COAST composite score for MM participants was 1.3 ± 0.1 (n = 53) with a higher score indicating greater MM disease severity, and correlated to NSAA (r = −0.64, p < 0.0001, n = 52) to indicate clinical meaning. Test–retest reliability of MM‐COAST assessments in an MM subset (n = 14) revealed an intraclass correlation coefficient (ICC) of 0.81 (95% confidence interval: 0.59–0.92) indicating good reliability.ConclusionsWe have developed and successfully validated a MM‐specific Composite Assessment Tool to quantify the key domains of MM, shown to be abnormal in a Definite MM cohort. MM‐COAST may hold particular utility as a meaningful outcome measure in future MM intervention trials.

Background and purposeRestricted dorsiflexion range of motion (DFROM) could impact dynamic balance in sports. This study aimed to investigate the relationship between dorsiflexion range of motion and the Y‐Balance Test (YBT) in elite futsal players.MethodsSixty‐one asymptomatic male futsal players (mean age 26.57 (5.64) years, a mean body mass index of 25.40 (2.69) kg/m2) were included. DFROM was measured by the weight‐bearing lunge test (WBLT). DFROM data were obtained using smartphone‐based motion capture. The Pearson correlation coefficient verified the correlation between the variables.ResultsDominant and nondominant leg ankle DFROM was significantly correlated with the anterior component of YBT (r = 0.27 and 0.51, respectively). The posteromedial component and the composite score of the YBT were also significantly correlated with nondominant leg ankle DFROM (r = 0.31 and 0.34, respectively)]. The other measures were not statistically significant. DFROM explained between 7% and 24% of the variation of the distances reached in the YBT.ConclusionDorsiflexion range of motion measured by weight bearing lunge test is positively correlated with dynamic balance in futsal players.
