INTRODUÇÃO: Diferentes modalidades esportivas utilizam as mãos como importante seguimento corporal envolvido para o desempenho. Entre essas modalidades destacam-se judô, tênis, vela, remo, boxe, levantamento de peso e outras. A força de preensão manual é exigida nessas modalidades específicas, em que o nível de força gerado pode ser o diferencial no desempenho final. A dinamometria manual é um valioso instrumento a ser utilizado na detecção do talento esportivo, no controle do treinamento e na avaliação de recuperação de lesão. OBJETIVOS: O objetivo deste estudo é fazer uma revisão sobre os principais aspectos metodológicos envolvidos na mensuração da força de preensão manual, utilizando o dinamômetro Jamar®, identificando os aspectos relacionados à validade, confiabilidade, precisão, posição para realização do teste, posição da alça, instruções, número de medidas, período de descanso entre as tentativas, duração do tempo de contração, aquecimento pré-teste. MATERIAIS E MÉTODOS: Foi realizado um levantamento para compor uma base de dados de diferentes modalidades olímpicas: coletivas e individuais. Foi realizada uma pesquisa eletrônica da literatura utilizando as bases de dados MEDLINE, SciELO e LILACS, sendo utilizados os seguintes descritores: força de preensão manual, dinamometria manual e, em inglês, hand, grip, strength, dynamometer, Jamar, norms e reference values. CONCLUSÃO: Os valores de força de preensão manual apresentados pelos atletas diferem de acordo com a modalidade, sexo, peso corporal, nível do atleta, idade e tipo de treinamento. A força de preensão manual deve estar presente nas baterias de testes para identificação de possíveis talentos esportivos.

The aim of the study was to analyze total and regional body composition in Tai Chi Chuan (TCC) middle-aged and elderly practitioners. A cross-sectional study on 139 Italian subjects was realized: 34 TCC practitioners (14 men, 20 women; 62.8 ± 7.4 years) and 105 sedentary volunteers (49 men, 56 women; 62.8 ± 6.4 years). Anthropometric measurements (height, weight, arm, waist, and calf circumferences), hand-grip strength, and physical capacity values were collected. Total and regional (arm, leg, and trunk) body composition was analyzed by means of specific bioelectrical impedance vector analysis (specific BIVA). TCC practitioners of both sexes were characterized by a normal nutritional status, normal levels of physical capacity, and normal values of hand-grip strength. Compared to controls, they showed lower percentages of fat mass (lower specific resistance) in the total body, the arm, and the trunk, and higher muscle mass (higher phase angle) in the trunk, but lower muscle mass in the arm. Sexual dimorphism was characterized by higher muscle mass (total body, arm, and trunk) and lower %FM (arm) in men; sex differences were less accentuated among TCC practitioners than in the control. TCC middle-aged and elderly practitioners appear to be less affected by the process of physiological aging and the associated fat mass changes, compared to sedentary people.

AbstractThe importance of dietary protein for the maintenance of muscle mass and strength is heavily discussed. However, adequate energy intake is an underlying assumption but often not considered. In this study, we investigated the impact of daily intake and meal distribution of both protein and energy on muscle mass and strength. In a cross-sectional study, a total of 184 older individuals (gender: 86F/98M, age: 70.2 ± 3.9 yrs, BMI: 25.4 ± 3.7 kg/m2; means ± SD) were recruited. Participants underwent a 3-day weighed dietary record, Dual-energy X-ray Absorptiometry (DXA) scan, hand-grip strength, and Maximal Voluntary Isometric knee-extension Contraction (MVIC). Participants were divided into two categories: lower (LOW; < 0.83 g/adjusted(a)BW/day) or higher (HIGH; ≥ 1.1 g/aBW/day) protein intake levels analysed by gender to characterize a daily protein and energy intake pattern. Main meal protein and energy intake distributions were calculated, and correlations were made. Further, energy intake at breakfast and lunch divided by total energy intake (energy ratio) was correlated with appendicular skeletal muscle index (ASMI), hand-grip strength, and MVIC were determined using the LOW/HIGH-protein-intake categorization. Further, gender-specific ASMI, hand-grip strength and knee extension were compared based on the following four distinct daily protein intake ranges: < 0.66; ≥ 0.66- < 0.83; ≥ 0.83- < 1.1; ≥ 1.1 g/aBW/day. A positive correlation appeared between protein and energy intake in all main meals (r ≥ 0.57, p < 0.0001). In the LOW category, positive correlations were found between energy ratio and ASMI (r = 0.16, p = 0.048), hand-grip strength (r = 0.40, p = 0.0009), and MVIC (r = 0.36, p = 0.0019), whereas no associations were found in the HIGH category. ASMI, hand grip, and MVIC were similar regardless of the protein intake ranges, though with women being lower than men (p < 0.05) in all outcomes. These results show that total daily protein intake did not affect muscle mass and strength in our cohort. However, our data demonstrate that greater energy intake in breakfast and lunch relative to total energy intake is associated with higher muscle mass and strength, particularly when protein intake is lower than 0.83 g/aBW/day, indicating the potential importance of meal energy content at lower intakes of protein.

Abstract Background: Sarcopenia is a skeletal muscle disease of clinical importance that occurs commonly in old age and in various disease sub-categories. Widening the scope of knowledge of the genetics of muscle mass and strength is important because may allows us to identify new genetic markers or identify patients with an increased risk to develop a specific musculoskeletal diseases or condition such as sarcopenia. It might also allow us to identify drugs that affect muscle in ways unknown before and therefore to reposition drugs to other uses, in accordance to their newly found target. We used bioinformatics tools to identify gene loci responsible for regulating muscle strength and lean muscle mass, which can then be a target for downstream lab experimentation validation. SNPs associated with various disease traits for the muscles and specific loci were chosen according to their muscle phenotype association p-value, as traditionally done in the GWASs. We developed and applied a combination of expression quantitative trait loci study (eQTLs) and GWAS summary information, to prioritize causative SNP and point out the unique genes associated in the tissues of interest (muscle). Results: We found NUDT3 and KLF5 for lean mass and HLA-DQB1-AS1 for hand grip strength as candidate genes to target for these phenotypes. The associated regulatory SNPs are rs464553, rs1028883 and rs3129753 respectively. Conclusion: TWAS approaches of combining GWAS and eQTL summary statistics proved helpful in statistically prioritizing genes and their associated SNPs for the disease phenotype of study, here, Sarcopenia. Potentially regulatory SNPs associated with these genes can be analyzed with respect to TADs and then targeted for knock out in either C2C12 mouse myoblast cells, adipocytes or any other relevant cell, depending on the phenotype it is hypothesized to affect, as a downstream experimental validation plan.
