“…By correlating lean mass and maximal voluntary isometric contraction it has been observed that the higher the lean mass, the better muscle performance , corroborating the study by Orsatti et al ., 22 who found in 52 sedentary women, aged between 40 and 70 years , the same relationship between lean body mass and muscle strength. Carmeli et al 23 .…”

Objective: To correlate muscule performance, body composition, pain and joint function in elderly people with gonarthrosis. Method: 21 elderly patients were submitted to bioelectrical impedance analysis, dynamometry associated with electromyographic (EMG) evaluation of isometric knee extension, in addition to pain assessment by the Numeric Pain Intensity Scale and function assessment, by the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis (OA) questionnaire. Correlations were checked by the Pearson's correlation coefficient. Results: The sample characteristics were mean age 67.36 ± 4.21 years old, body fat percentage 40.57±6.15%, total WOMAC score 43.27 ± 16.32%, and maximum strength 19.95 ± 6.99 kgF. Pain during movement showed a statistical association with WOMAC physical activity domain (r = 0.47) and its general score (r = 0.51); pain intensity at night presented association with WOMAC stiffness domain (r = 0.55), in addition to the negative correlation with the slope values of the Medium Frequency of the EMG signal (r = - 0.57). Conclusion: pain intensity is correlated to functional incapacity in elderly people with knee OA and to a greater expression of fatigue in EMG signal.

“…Moreover, attendance of at least 75% of the functional fitness classes was required, with a time of practicing the activities of greater than one year. Initially, the gender of the individual was not constituted to be an exclusion factor, however, after matching data, it was found that the number of elderly males was low (15), complicating the statistical tests. As a result, these individuals were excluded, and the study was restricted to the female gender.…”

Minute Walk Test) was used. The intervention period lasted for eight months, and the detraining period took three months. Descriptive and inferential statistics with paired Student t-test and Scheffé post hoc was used. Results: The performance of the age groups differed in agility and aerobic capacity; Trainability was identified in the strength and resistance variables of the lower and upper limbs, and the flexibility of the lower limbs; Detraining was perceived in the strength and resistance of upper limbs, and aerobic capacity. Conclusion: A Functional Gymnastics program produces positive effects on the strength and resistance of the lower and upper limbs, and flexibility of the lower limbs in elderly women. An interruption period lasting three months results in detraining in strength and resistance of the lower limbs and aerobic capacity.

“…Conforme Orsatti et al (2011) após a 7ª década de vida o avanço progressivo desta perda de força muscular pode levar o idoso a um estado de impossibilidade física, que impossível a realização de atividades comuns da vida diária, como por exemplo: levantar-se da cadeira, subir escadas, varrer o chão ou tomar banho. O que por sua vez, acaba contribuindo expressivamente para o desenvolvimento da fragilidade e diminuição funcional.…”

Com o envelhecimento o sistema musculoesquelético vai se transformando progressivamente e passa a adquirir características estruturais e morfológicas específicas que prejudicam a capacidade funcional e física do indivíduo. O estudo tem como objetivo verificar e descrever as principais alterações morfofisiológicas decorrentes do processo de envelhecimento no sistema musculoesquelético e as suas consequências para o organismo. A literatura pesquisada evidência que a partir da 4ª década de vida ocorrer uma perda progressiva e absoluta da massa óssea, associada com alterações no tecido cartilaginoso, tendinoso e ligamentar, que se tornam mais rígidos, a massa muscular magra sofre descréscimo de 10%-16% após este período e a força muscular é reduzida em 15% por década após os 40 anos. Isso leva a uma diminuição da coordenação motora, da capacidade de realizar atividades de vida diária, podendo levar o idoso a um estado de impossibilidade física que influenciam negativamente na velocidade do caminhar, do subir escadas e do levantar-se da posição sentada para a em pé. Ao término do estudo, concluiu-se que entre as principais alterações do sistema musculoesquelético decorrentes do processo de envelhecimento são, a redução da massa óssea e muscular, associada a uma diminuição da força, potência, resistência e flexibilidade muscular.
