Abstract Background and Aim In 2018, cancer survival (colorectal and breast cancer) rates at five years are estimated at 68%, which is very promising data, however this makes cancer a chronic disease. The illness itself and its treatment negatively affect muscle strength, functional capacity and body composition of these patients. This hampers the performance of activities of daily living, work and leisure. In recent years, ultrasound has evolved as being a useful, simple and innocuous tool to evaluate the muscle architecture in different groups of the population.Thus, the aim of this study was to determine whether the muscle architecture of the quadriceps, measured using ultrasound, is associated with muscle strength, functional capacity and body composition in patients with cancer (colorectal and breast cancer) who have completed medical treatment. Material and Methods A sample of 11 patients (n = 2 breast cancer and n = 9 colorectal cancer) were recruited from the University Hospital Virgen de las Nieves (Granada). An analytical, observational, cross-sectional study was performed in which the width of the quadriceps was assessed (distance between the upper border of the rectus femoris muscle and the superior margin of the femur) in a cross-sectional image using ultrasound (SAMSUNG, HM70A, Seoul, KR) in the dominant lower limb. Furthermore, we evaluated isokinetic muscle strength of knee extensors to 300°/s and isometric muscle strength of the quadriceps using the dynamometer (Humac Norm, 502140, Stoughton, MA), functional capacity using the 6-minute walk test and the percentage of fat and musculoskeletal mass using bioelectrical impedance (InBody 720; Biospace, Seoul, KR). For the analyses, Pearson's correlation coefficients were used before adjusting by age and partial correlation coefficients adjusting by age using IBM SPSS Statistics 21 software (IBM Corporation, Armonk, NY). Results The width of the quadriceps (mean ±  SD: 3.13 ±  0.57 cm) showed positive associations with isokinetic torque of extensors (r= 0.693), Q isometry (r = 0.657), musculoskeletal mass (r= 0.518), percentage of fat (r= 0.338) and functional capacity (r= 0.606); and negative associations with age (r= -0.158); although significance was only found for the isokinetic torque of extensors, quadriceps isometry and functional capacity (P < 0.05). The partial correlation of the isokinetic torque of extensors with the width of the quadriceps removing the effect of age was (r= 0.686, P= 0.029) and for quadriceps isometry (r= 0.650, P= 0.042). This partial correlation for functional capacity, removing the effect of age was r= 0.593 (P= 0.071). Conclusion Ultrasound can be a useful tool as an indicator of physical condition, in terms of strength of oncological patients. These findings support the use of ultrasound in the clinical context of oncological physical therapy as a possible method of functional assessment.

This study aimed to determine which of four selected physical fitness variables, would be most associated with blood pressure changes (systolic and diastolic) in a large sample of adolescents. This was a descriptive and cross-sectional, epidemiological study of 1,117 adolescents aged 14–19 years from southern Brazil. Systolic and diastolic blood pressure were measured by a digital pressure device, and the selected physical fitness variables were body composition (body mass index), flexibility (sit-and-reach test), muscle strength/resistance (manual dynamometer), and aerobic fitness (Modified Canadian Aerobic Fitness Test). Simple and multiple linear regression analyses revealed that aerobic fitness and muscle strength/resistance best explained variations in systolic blood pressure for boys (17.3% and 7.4% of variance) and girls (7.4% of variance). Aerobic fitness, body composition, and muscle strength/resistance are all important indicators of blood pressure control, but aerobic fitness was a stronger predictor of systolic blood pressure in boys and of diastolic blood pressure in both sexes.

Abstract In the present cross-sectional study of 403 independently living elderly men, we tested the hypothesis that the decreases in bone mass, body composition, and muscle strength with age are related to the fall in circulating endogenous testosterone (T) and estrogen concentrations. We compared various measures of the level of bioactive androgen and estrogen to which tissues are exposed. After exclusion of subjects with severe mobility problems and signs of dementia, 403 healthy men (age, 73–94 yr) were randomly selected from a population-based sample. Total T (TT), free T (FT), estrone (E1), estradiol (E2), and sex hormone-binding globulin (SHBG) were determined by RIA. Levels of non-SHBG-bound T (non-SHBG-T), FT (calc-FT), the TT/SHBG ratio, non-SHBG-bound E2, and free E2 were calculated. Physical characteristics of aging included muscle strength measured using dynamometry, total body bone mineral density (BMD), hip BMD, and body composition, including lean mass and fat mass, measured by dual-energy x-ray absorptiometry. In this population of healthy elderly men, calc-FT, non-SHBG-T, E1, and E2 (total, free, and non-SHBG bound) decreased significantly with age. T (total and non-SHBG-T) was positively related with muscle strength and total body BMD (for non-SHBG-T, respectively, β = 1.93 ± 0.52, P &lt; 0.001 and β = 0.011 ± 0.002, P &lt; 0.001). An inverse association existed between T and fat mass (β = −0.53 ± 0.15, P &lt; 0.001). Non-SHBG-T and calc-FT were more strongly related to muscle strength, BMD, and fat mass than TT and were also significantly related to hip BMD. E1 and E2 were both positively, independently associated with BMD (for E2, β = 0.21 ± 0.08, P &lt; 0.01). Non-SHBG-bound E2 was slightly strongly related to BMD than total E2. The positive relation between T and BMD was independent of E2. E1 and E2 were not related with muscle strength or body composition. In summary, bioavailable T, E1, total E2, and bioavailable E2 all decrease with age in healthy old men. In this cross-sectional study in healthy elderly men, non-SHBG-bound T seems to be the best parameter for serum levels of bioactive T, which seems to play a direct role in the various physiological changes that occur during aging. A positive relation with muscle strength and BMD and a negative relation with fat mass was found. In addition, both serum E1 and E2 seem to play a role in the age-related bone loss in elderly men, although the cross-sectional nature of the study precludes a definitive conclusion. Non-SHBG-bound E2 seems to be the best parameter of serum bioactive E2 in describing its positive relation with BMD.

Abstract Introduction: Individuals with chronic kidney disease (CKD) undergoing hemodialysis (HD) present low cardiorespiratory fitness and functional capacity. Metabolic changes, due to the disease, can result in a variety of pathophysiological conditions that favor the development of respiratory muscle weakness. However, very little is known about the performance of the respiratory muscles and the influence of HD on them. Aim: To evaluate and correlate pulmonary function, functional capacity and respiratory muscle strength in patients with CKD undergoing HD. Methods: Cross-sectional study comprising 23 patients with CKD, that met the following inclusion criteria: patients of both genders, who perform HD three times a week for a minimum period of three months. Respiratory muscle strength was evaluated using a respiratory pressure meter, lung function through spirometry and functional capacity through the 6-minute walk test (6MWT) before the HD session. Results: All patients were male and mean age was 50.2 ± 15.8 years. The median duration of HD was 3 (1.5 to 6.0) years. The mean values obtained in comparison to those predicted were MIP% 36.0 ± 13.6, MEP% 49.5 ± 15.8, FVC% 93.8 ± 21.1, FEV1% 93.7 ± 21.1, FVC/VEF1% 104.1 ± 10.3, and 6MWT% 66.33 ± 20.53. A statistically significant positive correlation was observed between the 6MWT and MIP (r = .63, p =.001) and MEP (r = .67, p < .001), between the MIP and MEP (r =.79, p < .001) and between the FEV1 and FVC (r = .91, p < .001). Conclusion: Patients with CKD undergoing HD present changes in respiratory muscle strength, with the predicted values decreasing for age and gender, as well as the distance covered in the 6MWT, although, with normal spirometric values. Functional capacity was dependent on respiratory muscle strength, as well as the values of MIP and MEP, and the values of FVC and FEV1.

Abstract Introduction: Despite the importance of appropriate levels of muscular strength to maintain the functional capacity and a healthy life in old age, the current literature still lacks studies that investigate the profile of elderly women who practice Mat Pilates regarding these variables. Objective: This study aimed to analyze muscular strength, functional capacity, and risk of sarcopenia in elderly women who practiced Mat Pilates. Method: This is a cross-sectional study carried out with 50 elderly women who practice Mat Pilates in the city of Maringá, Paraná. Sociodemographic and health questionnaires were used, in addition to tests created by a Latin American development group for maturity called Grupo de Desenvolvimento Latino Americano para a Maturidade (GDLAM), sitting-rising test, arm curl test, and SARC-F questionnaire. For data analysis, Shapiro-Wilk and Mann-Whitney U tests, as well as Spearman’s Rank Correlation Coefficients, were used. The level of significance was p < 0.05. Results: The 70-79-year-old elderly women showed worse results in the functional capacity and muscular strength tests of the upper limbs and a higher risk of sarcopenia than the individuals who were under 70 years of age. Muscular strength was inversely related to the reduction of the risk of sarcopenia, and functional capacity was directly associated with this risk. Conclusion: A good functional capacity seems to be related to the reduction of the risk of sarcopenia. Age seems to be an intervening factor for reducing muscular strength levels and functional capacity and increasing the risk of sarcopenia.

Background: Exercise has been shown to reduce adverse outcomes related to breast cancer. However, the rate of adherence to physical exercise is very low among breast cancer survivors (BCS). This study investigated the effects of high supervision ratio resistance training (RT), once a week for 8 weeks, on changes in body composition and muscular strength in BCS. Methods: Twenty-five female BCS undergoing hormone therapy were randomized into resistance training group (TG, n = 12) or control (CG, n = 13) group. The TG performed 8 weeks of supervised RT, with 1 trainer per volunteer, once a week. Body composition was evaluated by dual-energy X-ray absorptiometry, and muscle strength was evaluated by 10 repetition maximum (10 RM) for leg press (45°) and bench press exercises. A 1-way analysis of variance was used to compare within-group effects at pre- and post-intervention. An analysis of covariance test was used to compare post-intervention values, using pre-intervention measures as covariates. The effect size (ES) was calculated by Cohen’s d. Results: The TG improved muscle strength in 10 RM leg press (45°; Δ 33.75 ± 11.51 kg, P = .02; ES = 0.96) and bench press (Δ 4.08 ± 1.83 kg, P = .01; ES = 1.15). Adherence to training was more than 99%. Changes in body composition were not detected. There were no changes in the CG for any assessment. Conclusion: Once-weekly supervised RT could be an alternative to increase the adherence to exercise and improve muscular strength in BCS.

Introduction. The purpose of this study was to investigate body composition, muscle function, and muscle morphology in patients with spondyloarthritis (SpA).Methods. Ten male SpA patients (mean ± SD age39±4.1years) were compared with ten healthy controls matched for sex, age, body mass index, and self-reported level of physical exercise. Body composition was measured by dual energy X-ray absorptiometry. Musculus quadriceps femoris (QF) strength was assessed by maximal isometric contractions prior to test of muscular endurance. Magnetic resonance imaging of QF was used to measure muscle size and calculate specific muscle strength. Percutaneous needle biopsy samples were taken fromm. vastus lateralis.Results. SpA patients presented with significantly lower appendicular lean body mass (LBM) (p=0.02), but there was no difference in bone mineral density, fat mass, or total LBM. Absolute QF strength was significantly lower in SpA patients (p=0.03) with a parallel trend for specific strength (p=0.08). Biopsy samples from the SpA patients revealed significantly smaller cross-sectional area (CSA) of type II muscle fibers (p=0.04), but no difference in CSA type I fibers.Conclusions. Results indicate that the presence of SpA disease is associated with reduced appendicular LBM, muscle strength, and type II fiber CSA.

Abstract Background: Although there have been studies on the association between hypovitaminosis D status with muscle strength and functional capacity, there were few studies on Brazilian community-dwelling elderly population. Therefore, this study aims to assess the association of hypovitaminosis D with muscle strength and functional capacity in a sample Brazilian community-dwelling elderly population.Methods: An analytical, cross-sectional observational study with a convenience sample was conducted. The 25(OH)D levels were assessed using an enzyme-linked fluorescent assay and classified according to the standardization of the Brazilian Society of Clinical Pathology/Laboratory Medicine. Hand grip strength (HGS) and isometric quadriceps strength (IQS) were measured using manual Jamar® and Lafayette® 01165 dynamometers, respectively. Functional capacity was evaluated using the Short Physical Performance Battery (SPPB). Multiple linear regression models were used to assess the association of hypovitaminosis D with the HGS, IQS, and SPPB score via the Enter method. The models were adjusted for age, sex, presence of pain, level of physical activity, and use of vitamin D supplementation. Results: A total of 150 elderly individuals (age: 67.18±5.33 years) were included. According to the 25(OH)D levels, 60.7% had hypovitaminosis D (insufficient: 48%, deficient: 12.7%), and 39.3% had sufficient levels. No associations were found between hypovitaminosis D and the HGS (p=0.84), LogIQS (p=0.462), and SPPB score (p=0.617). In the regression model, the influence of the vitamin D levels on functional capacity was not significant, demonstrating no association between them.Conclusion: Hypovitaminosis D was not associated with decreased muscle strength and functional capacity in the sample Brazilian community-dwelling elderly population. Longitudinal studies with measurement of the time of use and levels of vitamin D are encouraged.

Abstract Introduction: Regular physical activity is one of the main ways of avoiding compromised functional capacity and gaining muscle mass. Objective: investigate the differences in muscle strength and functional capacity of elderly people engaged in two types of strength exercises. Method: a cross-sectional study of 80 seniors of both sexes, 40 of whom engaged in weight training and 40 from the Fitness Zone in the city of Maringá, Paraná, state. A sociodemographic questionnaire, the sitting-rising and elbow flexion tests, and the functional capacity tests of the Latin American Development Maturity Group (GDLAM) were applied. The data were analyzed using the Shapiro-Wilk, Mann-Whitney “U” and Spearman’s correlation tests (p<0.05). Results: Most seniors who performed well in the sitting and rising test, rising from a chair and moving around the house and rising from the dorsal decubitus position engaged in weight training (p=0.001). Those engaged in weight training exhibited better upper limb strength and functional capacity in all the tests performed (p <0.05). Muscle strength is inversely related to functional capacity, that is, the better the result in the upper and lower limb muscle strength tests, the better the functional capacity of the elderly engaged in weight training. Conclusion: According to the results obtained, older people who engage in weight training display better upper limb strength and functional capacity than seniors from the Fitness Zone.
