The aims of the current study were to analyze a kick from 10 m in a futsal context and the parameters of muscular strength using an isokinetic dynamometer in a laboratory environment, performed with the dominant (DL) and nondominant lower limbs (NDL). Seventeen professional elite players participated. Kicking performance was evaluated from the second penalty mark. Next, athletes completed a strength evaluation with an isokinetic dynamometer at speeds of 60°⋅s, 180°⋅s, and 300°⋅s. Significant differences were observed for hip (15.64 ± 3.44; 13.97 ± 2.62), ankle (63.19 ± 8.90; 52.55 ± 8.72), foot (82.31 ± 7.93; 68.41 ± 7.85), and ball (99.74 ± 8.45; 88.31 ± 7.93) speeds (km⋅h), and average power at 180°⋅s (325.59 ± 40.47; 315.79 ± 39.49 W), but not for accuracy (1.33 ± 0.57; 1.66 ± 0.77 m) between the DL and NDL, respectively. Few moderate correlations were observed in the DL (r = .54-.64) or NDL (r = .53-.55) between the kinematic variables of kick and muscular strength parameters (P < .05). We conclude that highly trained players present asymmetries in kicking motion; however, the imbalance in muscular strength is very small. We recommend that specific court tests be conducted to reliably characterize kicking performance in futsal. Success in kicking seems to be too variable and complex to be totally predicted only by joints, foot and ball speed, and lower limb muscular strength parameters.

A maximal 3-min effort test resulted in altered scapular biomechanics. More studies are needed to verify if the changes correspond to a risk factor for injuries.

Background Upper extremity musculoskeletal disorders negatively affect ability to perform activities of daily living, self-care and work. Therefore, outcome measurements that address muscle strength, fatigue resistance, functionality and work physical capacity must be defined to assess and plan specific actions to minimize them. Objective To investigate the association of upper extremity muscle strength with upper extremity fatigue resistance, work ability and upper extremity dysfunction in a sample of workers from a tertiary hospital. Methods Shoulder and elbow isokinetic strength were assessed by Biodex System 4™, isometric hand grip by JAMAR™, upper extremity fatigue resistance by Functional Impairment Test Hand and Neck/Shoulder/Arm (FIT-HaNSA), ability to work by the Work Ability Index and upper extremity dysfunction by the Quick-Disabilities of the Arm, Shoulder and Hand QuickDASH-Br questionnaire. The Nordic questionnaire and Numeric Pain Rating Scale (NPRS) were used for pain description. The associations were analysed by Spearman’s correlation coefficient (rho) (p < 0.05). Results Twenty-seven participants: 59.2% women; mean age 46 years old; 70.3% obese/overweight; 62.9% active with predominantly dynamic muscle contraction work. Besides predominance of good to moderate work ability (81.4%) and comorbidities (37%), all participants had symptoms of the upper extremities for at least 12 months, with a predominance of low-intensity in the shoulder (55.5%). In addition, 88.8% reported pain in other segments. Muscle strength of abduction (rho = 0.49), adduction (rho = 0.40), internal rotation (rho = 0.44) and hand grip (rho = 0.68) presented moderate correlation with FIT-HaNSA. Hand grip (rho = − 0.52) showed moderate correlation with upper extremity dysfunction. Conclusions The results of this preliminary study suggested the association of shoulder strength with fatigue resistance. Also, hand grip strength was associated with upper extremity dysfunction and fatigue resistance. No association was found with the Work Ability Index in this sample. So, it is suggested that hand grip and shoulder strength could be outcome measurements used for future interventions focused on upper extremity preventive exercises to improve strength and fatigue resistance of workers at risk for the development of musculoskeletal disorders. Other individual, psychosocial and organizational risk factors must also be considered as influences on upper extremity function.

Introdução: As falhas de cobertura nas extremidades são um grande desafio terapêutico. Dentre as várias opções disponíveis para manejo da cobertura encontra-se o retalho livre do Músculo Grande Dorsal, devido sua grande versatilidade e características anatômicas do pedículo. Objetivo: avaliação da morbidade da área doadora do retalho livre de grande dorsal. Métodos: 7 pacientes avaliados em relação a morbidade da área doadora, seja pelo componente estético, álgico e funcional (amplitude de movimento residual). Resultados: 71,4% dos pacientes repetiriam o mesmo procedimento cirúrgico se necessário. 85,7% indicariam o mesmo procedimento para outros pacientes. Discussão: Devido baixa morbidade da área doadora, o retalho livre de grande dorsal encontra-se uma excelente opção na literatura. Nossos dados corroboram com os resultados apresentados em outros estudos, porém com algumas variações na amplitude de movimento mensurada nos pacientes. Conclusões: Devido grande versatilidade e baixa morbidade na área doadora, o retalho livre de Grande Dorsal é uma excelente opção para falhas de cobertura.Descritores: Retalhos Cirúrgicos; Microcirurgia; Procedimentos Cirúrgicos Reconstrutivos.ReferênciasPederson WC.

Introduction: Kinesio taping consists of the attachment of a thin elastic tape over specific muscles, the thickness of which is similar to that of the epidermis. This tape can be stretched to 140% of its original length, which demonstrates greater elasticity in comparison to conventional bandages. According to the creator of this method, Kinesio taping leads to better muscle activation or inhibition, reduces pain, swelling and muscle spasms and prevents muscle injury. Objective: The aim of the proposed study is to compare and analyze the immediate effect of Kinesio taping and placebo taping on performance during unilateral vertical jump and two hop tests by young professional soccer players. Methods: A randomized, placebo-controlled, double-blind, clinical trial will be conducted involving 100 athletes. The volunteers will be submitted to an evaluation of the dominant lower limb using the Single Leg Hop Test and Single Leg Triple Hop Test as well as the evaluation of a unilateral vertical jump on a pressure platform. The athletes will then be randomly allocated to two groups. Group A will receive Kinesio taping of the triceps surae muscle as described by Kase (2003, 2013) and Group B will receive a placebo taping of the same muscle. After 30 minutes, the volunteers will be submitted to the same evaluation tests. Analysis: Intra-group and inter-group analyses of the results will be performed. Statistical tests will be conducted considering a 5% significance level. This study is registered with Clinical Trials under protocol number: NCT02560961
