“…Our results indicated deficits of 16% to 35% in individuals with AT, suggesting that these tests may be an appropriate way of assessing reactive-strength deficits in AT. Various hopping tasks have the advantage of being inexpensive, quick, and reliable in research and clinical settings 59 ; however, in isolation, they may not discriminate between people using very different movement patterns to achieve hop distances, and hopping does not isolate the PF muscle group. Similar magnitudes of deficits in reactive strength have also been reported after ankle 60 and anterior cruciate ligament 58,61 injury.…”

Background Persistent strength deficits secondary to Achilles tendinopathy (AT) have been postulated to account for difficulty engaging in tendon-loading movements, such as running and jumping, and may contribute to the increased risk of recurrence. To date, little consensus exists on the presence of strength deficits in AT. Consequently, researchers are uncertain about the appropriate methods of assessment that may inform rehabilitation in clinical practice. Objective To evaluate and synthesize the literature investigating plantar-flexion (PF) strength in individuals with AT. Study Selection Two independent reviewers searched 9 electronic databases using an agreed-upon set of key words. Data Extraction Data were extracted from studies comparing strength measures (maximal, reactive, and explosive strength) between individuals with AT and healthy control participants or between the injured and uninjured sides of people with AT. The Critical Appraisal Skills Programme Case-Control Study Checklist was used to assess the risk of bias for the included studies. Data Synthesis A total of 19 studies were eligible. Pooled meta-analyses for isokinetic dynamometry demonstrated reductions in maximal strength (concentric PF peak torque [PT] slow [Hedges g = 0.52, 44% deficit], concentric PF PT fast [Hedges g = 0.61, 38% deficit], and eccentric PF PT slow [Hedges g = 0.26, 18% deficit]). Reactive strength, particularly during hopping, was also reduced (Hedges g range = 0.32–2.61, 16%–35% deficit). For explosive strength, reductions in the rate of force development (Hedges g range = 0.31–1.73, 10%–21% deficit) were observed, whereas the findings for ground reaction force varied but were not consistently altered. Conclusions Individuals with AT demonstrated strength deficits compared with the uninjured side or with asymptomatic control participants. Deficits were reported across the strength spectrum for maximal, reactive, and explosive strength. Clinicians and researchers may need to adapt their assessment of Achilles tendon function, which may ultimately help to optimize rehabilitation outcomes.

“…Swearingen et al (16) presented similar findings in a study of healthy patients of both sexes who averaged 24 years of age (19). However, in a study of healthy subjects and sports players, van der Harst et al (20) found no differences between the dominant and non-dominant legs in single hop test and timed hop test evaluations.…”

OBJECTIVE:Most injuries occur during the final 15 minutes of each half of a soccer match, suggesting that physical exertion may influence changes in neuromuscular control and the body's ability to stabilize the joints of the lower extremities. The aim of this study was to analyze the effects of one-half of a soccer match on the functional capacity and stability of the lower limbs in young soccer players.METHODS:We analyzed 27 soccer players by evaluating the functional capacity of their lower limbs using the hop test protocol and their level of postural stability using the Biodex Stability System. The evaluations were performed before and after 45 minutes of game time.RESULTS:After the match, there was a decrease in the overall stability index (OSI) (F(1,23) = 5.64, p = 0.026) and the anterior-posterior stability index (APSI) (F(1,23) = 5.24,p = 0.032). In the single and triple hop tests, there was a higher functional capacity in the dominant limb compared to the non-dominant limb in the pre- and post-game comparisons.CONCLUSION:The results of this study show that there is a decrease in the stability of the lower limbs in young soccer players after a 45 minutes soccer match, but the same result was not found for the functional capacity.

“…É importante mencionar que, apesar da relevância das medidas de força como uma forma de avaliar se e como a fraqueza muscular pode afetar o recrutamento de unidades motoras, uma avaliação funcional parece necessária para oferecer maiores detalhes sobre o desempenho muscular, uma vez que simula situações que são comuns às atividades esportivas. Neste sentido, os resultados do presente estudo concordam com outros trabalhos que utilizaram o single leg hop test 13,21,24,25 , o vertical jump 13,24,21,26 , o single leg hop for time 24 Deste modo, os resultados do presente estudo sugerem a existência de uma simetria funcional entre os membros inferiores em atletas recreacionais, e que a dominância de membros parece não ter efeito sobre essa condição. Esses resultados são úteis na medida em que fornecem informações adicionais sobre o desempenho funcional de atletas, considerando os aspectos relacionados à dominância de membros e, ao mesmo tempo, são necessários ao conhecimento do fisioterapeuta devido ao amplo uso desses testes no ambiente clínico, tanto para avaliação, quanto para a reabilitação de atletas.…”

ResumoObjetivo: Investigar a influência da dominância de membros sobre o desempenho dos membros inferiores em testes funcionais. Métodos: Oito atletas recreacionais (20,702,19 anos; 75,9015,30 kg; 1,730,07 m), de ambos os sexos, fizeram parte deste estudo-piloto. O desempenho funcional dos membros inferiores foi avaliado por meio de três testes de salto unipodal: hop test (HP), six-meter timed hop test (STHT) e square hop test (SHT), sendo considerado, em cada teste, o desempenho médio de três tentativas válidas, para a análise dos dados. Resultados: De acordo com o teste t-Student para amostras dependentes (=5%), não houve diferença significativa entre o desempenho dos membros dominante e não-dominante, nos três testes funcionais: HT (p=0,27), STHT (p=0,70) e SHT (p=0,23). Conclusão: A dominância de membros inferiores parece não influenciar de forma decisiva o desempenho funcional de atletas recreacionais.Palavras-Chave: dominância cerebral, membros inferiores, avaliação do desempenho. AbstractObjective: To investigate the influence of limb dominance on lower limb performance in functional tests. Methods: Eight recreational athletes (20.702.19 years, 75.9015.30 kg, 1.730.07 m), of both sexes, were took part of this pilot-study. The lower limb functional performance was evaluated by means of three single-leg hop tests: hop test (HP), six-meter timed hop test (STHT) and square hop test (SHT). Each test considered the average performance of three valid attempts to data analyzes. Results: According to the Student's t-test for dependent samples (= 5%), there was no significant difference between dominant and non-dominant limbs performance in the three functional tests: HT (p= 0.27), STHT (p= 0.70) and SHT (p= 0.23). Conclusion: The lower limb dominance does not seem to influence decisively the functional performance of recreational athletes.
