“…The present analyses found that anthropometric outcomes were not statistically significant in the hop test result. Although it has been proposed that the results of the hop test should be expressed in relation to the length of the lower limb 46 , the findings of the present study did not certify that assumption. A longer leg length means that a greater horizontal distance may be achieved.…”

To analyze the impact of balance, lower-limb explosive strength and anthropometric variables on the result of the hop test in young elite female basketball athletes. Ninety young elite female basketball athletes (13–17 years), without current or recent lower-limb injury, were assessed in the off-season period of July 2021. Single leg hop test, countermovement jump, Y balance test and anthropometric outcomes were assessed. A correlation study and a regression model were performed to investigate the influence of such outcomes and the value of their participation on the hop test results. It was found a low-to-moderate correlation effect size for both countermovement jump (distance and power flight) and Y balance test values (except interlimb outcomes) with the single leg hop test results. Anthropometric outcomes did not show significant correlation (p > 0.05). Regression model revealed that for right hop test, countermovement jump values exhibited an adjusted determination coefficient of 0.408, (β = 0.249, p = 0.013), For left hop test, again the countermovement jump values (β = 0.229, p = 0.025), and left Y balance test values (β = 0.331, p = 0.011) jointly obtained an adjusted determination coefficient of 0.263 significant predictive value for countermovement jump outcomes in both right (β = 0.249, p = 0.013; β = 0.301; p = 0.031) and left leg (β = 0.229, p = 0.025; β = 0.365, p = 0.040), as well as certain Y balance outcomes values. Explosive strength, and dynamic balance although to a lesser extent, appear to be the most relevant physical-functional factors influencing the single leg hop test results among young elite female basketball athletes. These findings may a serve as a basis to implement targeted interventions, such as plyometric and balance training, for an enhancement on functional rehabilitation and reducing the risk of injury related to the hop test results.

“…Interlimb-hop differences are other common expression of the hop test results, due to its capacity to detect functional differences [39]. However, in the present study, no variables related to this result were found.…”

“…At the same time, none on the anthropometric outcomes evaluated seem to be relevant components for the single leg hop test results. Length leg has been proposed as an aspect to be taken into account when expressing the results of the hop test [39], but this was not the case in the current study.…”

Objective To analyze the impact of balance, lower-limb explosive strength and anthropometric variables on the result of the hop test in young elite female basketball athletes. Methods Ninety young elite female basketball athletes (13–17 years), without current or recent lower-limb injury, were assessed in the off-season period of July 2021. Single leg hop test, countermovement jump, Y balance test and anthropometric outcomes were assessed. A correlation study and a regression model were performed to investigate the influence of such outcomes and the value of their participation on the hop test results. Results It was found a low-to-moderate correlation effect size for both countermovement jump (distance and power flight) and Y balance test values (except interlimb outcomes) with the single leg hop test results. Anthropometric outcomes did not show significant correlation (p > 0.05). Regression model revealed significant predictive value for countermovement jump outcomes in both right (β = 0.249, p = 0.013; β = 0.301; p = 0.031) and left leg (β = 0.229, p = 0.025; β = 0.365, p = 0.040), as well as certain Y balance outcomes values. Conclusions Among young elite female basket athletes, the explosive strength, measured with the countermovement jump, seems to be a relevant functional component for the results of the single leg hop test. Also, dynamic balance, but with a minor influence. Focusing on the elements that compose the hop test helps to improve the understanding and the design of specific interventions to enhance the test's performance.

“…53 Other Additional assessments of dynamic postural stability that have demonstrated value in assessing subtle sensorimotor impairments following SRC (mean time from injury 11.4 days) include the Biodex Sway System with an ideal cut point of 1.37 (sensi-tivity=37%, specificity=88%), 42 The Sensory Organisation Test, 54 and the Multiple Hop Test. 55 Individual components of complex tandem gait outperformed overall composites, specifically, walking forward eyes open (specificity=99%) and walking backward eyes closed (sensitivity=81%). 42 In most studies, balance and gait assessments demonstrated worse distributions in concussed compared with non-concussed athletes.…”

ObjectivesTo systematically review the scientific literature regarding the assessment of sport-related concussion (SRC) in the subacute phase (3–30 days) and provide recommendations for developing a Sport Concussion Office Assessment Tool (SCOAT6).Data sourcesMEDLINE, Embase, PsycINFO, Cochrane CENTRAL, CINAHL, SPORTDiscus and Web of Science searched from 2001 to 2022. Data extracted included study design, population, definition of SRC diagnosis, outcome measure(s) and results.Eligibility criteria(1) Original research, cohort studies, case–control studies, diagnostic accuracy and case series with samples >10; (2) SRC; (3) screening/technology that assessed SRC in the subacute period and (4) low risk of bias (ROB). ROB was performed using adapted Scottish Intercollegiate Guidelines Network criteria. Quality of evidence was evaluated using the Strength of Recommendation Taxonomy classification.ResultsOf 9913 studies screened, 127 met inclusion, assessing 12 overlapping domains. Results were summarised narratively. Studies of acceptable (81) or high (2) quality were used to inform the SCOAT6, finding sufficient evidence for including the assessment of autonomic function, dual gait, vestibular ocular motor screening (VOMS) and mental health screening.ConclusionCurrent SRC tools have limited utility beyond 72 hours. Incorporation of a multimodal clinical assessment in the subacute phase of SRC may include symptom evaluation, orthostatic hypotension screen, verbal neurocognitive tests, cervical spine evaluation, neurological screen, Modified Balance Error Scoring System, single/dual task tandem gait, modified VOMS and provocative exercise tests. Screens for sleep disturbance, anxiety and depression are recommended. Studies to evaluate the psychometric properties, clinical feasibility in different environments and time frames are needed.PROSPERO registration numberCRD42020154787.
