Identifying indicators that contribute to a favourable living condition becomes of great value for the diagnosis, as well as implementing preventive and health-promoting actions. The present work objective was to evaluate and compare the lifestyle, depressive symptoms and functional aptitude of elderly men and women attending a community centre. The sample consisted of 277 elderly people, 197 (71%) women and 80 (29%) men aged above 60 years. The elderly were evaluated using a questionnaire to assess lifestyle and depressive symptoms, and their functional fitness was assessed by functional autonomy tests. The differences between the parameters were analysed by the student's t-test and χ² whenever appropriate. Depressive symptoms were present in 35% of the elderly; however, the lifestyle analysis showed that 57.40% of the elderly had a very good classification, followed by 24.55% as good, 17.33% as excellent and 0.72% as regular. Regarding functional fitness, 19.39% of the elderly had a score related to a very good level, 15.97% good, 16.35% fair and 45.29% weak. The results found in this study suggest that the elderly attending the community centre presented low depressive symptoms with a lifestyle classification considered very good, however, with poor functional fitness with differences in some parameters between men and women.

The aim of this study was to investigate the association between low handgrip strength and blood pressure and blood lipid profile in elderly people. Data from 707 Brazilian elderly people aged 60 yrs and over were collected from January to December 2016. Participants attended to Hospital Israelita Albert Einstein and received anthropometric evaluation that included blood pressure, handgrip strength, and blood analysis. The Odd Ratio (OR) analysis showed a significant association between low handgrip strength and change in Low Density Lipoprotein Cholesterol (LDL-C) in elderly of both sexes (OR = 3.06 CI 95% 1.08 to 8.72). When adjusted to sex, low handgrip strength did not show association with any other blood and pressure parameters. When adjusted to age, low handgrip strength was associated with higher levels of Total Cholesterol (OR = 2.00; CI 95% = 1.29 to 3.10) and Triglycerides (OR = 1.29; CI 95% = 1.01 to 1.67) in the elderly aged 80 or over. In this way, handgrip strength evaluation may be considered a low cost and simple strategy as a preventive evaluation of cardiovascular risk in this population. [ABSTRACT FROM AUTHOR]

Background: The chronic low back pain (LBP) had been considered an important occupational disorder with several strategy available to treatment, however, few studies had been evaluated the treatment combination. Objectives: The aim of present study was compared the effects of combination of crocheting associated to Kinesiotherapy treatment and Kinesiotherapy isolated treatment on function of lumbar spine and pain during achievement of daily life in patients with chronic LBP. Methods: Forty subjects were distributed randomly in two groups: Crochetagem + Kinesioterapy (C; n: 18; 47.5 ± 7.75 years) and Kinesiotherapy (K, n: 18; 45.3 ± 8.93 years). The C group was treated by crocheting technique associated with kinesiotherapy using therapeutic ball. The K group performed a kinesiotherapy treatment using just a therapeutic ball. The following parameters were evaluated: abdominal strength, articular range motion and the data of Rolland Morris and Oswestry Disability Index questionnaires were evaluated before and after 8 weeks of treatment. Both groups performed all therapeutic sessions for 50 minutes, three times a week. Results: Significant differences (p<0.05) were found just on time to trunk flexion and extension, right and left lateral trunk, pain and abdominal strength. However, significant differences on time (p<0.05) was found on Rolland Morris and Oswestry data questionaries parameters just on C group, additionally the values of C group were lower than K group after treatment. Conclusion: Both kinesiotherapy isolated and association of crocheting and kinesiotherapy were useful to improve functional parameters, however the data from Rolland Morris and Oswestry questionaries were lower just on crocheting associated to kinesiotherapy group indicating increment on function of lumbar spine and decrease on pain during achievement of daily life.

Background: It is known that adolescence is a phase of transformation subject to innumerable influences. Objective: The objective of this study was to identify the level of body satisfaction among male adolescents practicing bodybuilding and perception and value attributed to the use of anabolic steroids (AS). Methods: The sample consisted of 3150 male adolescents aged 15 to 21 years. The adolescents were submitted to a questionnaire with 41 questions containing several elements detected such as: the level of body satisfaction, the bodybuilding practice proposing body changes and the possible use of AS. Results: The main results were attributed to the high level of satisfaction for body image variables from the members of their social group in 1883 (60%, χ= 26.361; p<0.005), body mass 1552 (50%; χ = 55.374; p<0.005) and muscle mass 1199 (39%, χ= 10.405; p <0.005). Additionally, 1243 (39%; χ= 31.926; p <0.005) adolescents confirm the possibility of use; the preference for faster means to achieve changes in their bodies, even knowing about health risks was 1347 (43%; χ= 31.926; p<0.005). On the knowledge of the effects to the point of refusing their involvement related to the use of AS with aesthetic objectives 1152 (36%; χ= 45.758; p<0.005) students affirm that they did not know, however, they would still use it, with statistically significant observed differences. Conclusion: Although it is possible to consider a high level of satisfaction for the variables associated with body image, adolescents consider the use of AS to achieve changes in their bodies by faster means, despite knowing about health risks even without knowledge of the effects related to the use of AS for aesthetic purposes.

Introduction: Aging is an irreversible physiological process that promote changes on biological parameters that culminate in limitations in the execution of daily tasks Objective: Evaluate the morphofunctional parameters of the elderly with and without depressive symptomatology. Methods: A cross-sectional descriptive exploratory study was carried out using the protocol of evaluation of the functional autonomy of the Latin American Development Group for Maturity (GDLAN Protocol), consisting of walking 10 meters (C10m), rising from the sitting position (LPS), rising from the ventral position (LPDV) and rising from a chair and moving around the house (LCLC). Results: No significant differences (p>0.05) were found between the groups on functional tests and anthropometric parameters, however, statistical differences (p = 0.001) were found between the groups in the general GDLAM index. Additionally, a positive correlation (r²: 0.778; p<0.01) was observed between the scores of depressive symptomatology and the general index GDLAM indicating that impairments in functional fitness proportionally higher incidence of depressive symptoms. Conclusion: The results suggest that elderly women with a depressive symptom present lower physical fitness than elderly women without symptoms of depression, and that physical activity is necessary for both samples to contribute to the improvement of daily life activities.

This study compared maximum oxygen consumption (VO2max) on a 20-meter multistage shuttle run test (20-Srt) with a cardiopulmonary exercise test (CPET) to determine a VO2max prediction equation for a 20-Srt in children aged 6-10 years. Eighty healthy children performed the CPET on a treadmill, while the 20-Srt took place on a sports court. Heart rate (HR) was measured and the expired gases were continuously measured breath-by-breath using a portable gas analyzer. The VO2max was lower (p < 0.05) in CPET than 20-Srt for all, female, and male participants, respectively (46.3 ± 7.9 vs. 48.7 ± 4.6; 42.7 ± 7.8 vs. 46.7 ± 4.8; 49.3 ± 6.8 vs. 50.4 ± 3.9, mL ⋅ kg-1 ⋅ min-1). The standard error estimates were between 3.0 and 3.6 and considered as not clinically relevant if less than 5 mL ⋅ kg-1 ⋅ min-1. The intraclass correlation coefficient between the VO2 in CPET and in 20-Srt was 0.74 (CI95 % 0.55-0.84) and considered moderately reliable. The linear multiple regression excluded sex, body mass index and fat-free mass and retained the maximum speed and age in the predictive equation. The 20-Srt estimates the VO2max with moderate reliability and the predictive equation was VO2maxpred = 4.302 + (maximum speed * 5.613)-(age * 1.523) for children aged 6-10 years.

It was our objective to analyze the effects of a single session of whole body HIIT on body-image and -scheme parameters of healthy adult men. Twenty-one active, healthy adults performed high-intensity intermittent training based on full body exercise. The training session involved 20 sets of 30 second all-out exercise and 30 seconds of passive recovery between sets. All subjects underwent blood lactate measurement, rate of perceived exertion, feeling scale and body image assessment and perception of body size measurements. Significant differences (p<0.001) were found on blood lactate but not in feeling scale. The values of current and adequate silhouette did not differ between each other and the real silhouette. Significant differences were found on Image Marking Procedure (IMP) (p< 0.003). Additionally, significant differences (p=0.009) were found on prevalence of adequate, hypoeschematic and hypeschematic. Although alteration was not found on self-perception of body image, a single session of HIIT body work promoted alteration on body size perception in healthy adult men. [ABSTRACT FROM AUTHOR]

Exercise training effects on the contractility of aged myocardium have been investigated for more than 20 years, but the data are still unclear. This study evaluated the hypothesis that a swimming training (ST) may improve myocardial inotropism in older rats. Male Wistar rats aged 4 (young)-and 21 (old)-months-old were divided into young untrained (YNT), old untrained (ONT), and old trained (OTR; 6 weeks of ST) groups. Echocardiography and hemodynamic were employed to assess left ventricular morphology and function. Myocardial mechanics was evaluated on papillary muscles. Histological and immunoblotting were carried out to evaluate fibrosis and proteins that modulate the myocardial function and calcium handling. We found that older rats did not show cardiac dysfunction, but ONT group showed lower physical performance during a swimming test (YNT: 5 ± 2; ONT: -16 ± 0.4; OTR: 51 ± 3; Δ%, sec). Moreover, ONT group showed worse myocardial inotropism, in which it was reversed by ST (Peak developed tension: YNT: 6.2 ± 0.7; ONT: 3.9 ± 0.3; OTR: 6.9 ± 0.9; g/mm2). The ST was associated with preserved collagen content (YNT: 0.38 ± 0.05; ONT: 0.78 ± 0.12; OTR: 0.34 ± 0.09; %). Exercise partially mitigated the effects of aging on intracellular Ca2+-regulating protein (eg, L-Ca2+ channel and phospholamban) and β-isoform of myosin. Thus, we propose that these molecular alterations together with inhibition of collagen increase contribute to improved myocardial performance in older rats. [ABSTRACT FROM AUTHOR]

The objectives of the present study were: 1st investigate if a verbal and demonstrative intervention at the moment discriminated as T2 promoted changes in coping strategies when compared to the T1 moment, 2nd investigate the behavior of the perception of efficacy after a verbal and demonstrative intervention at the time T2, 3rd to verify if the scores attributed in the proof of figures at time T2 were higher when compared to T1 moment. Methodology: 23 synchronized swimming athletes, participants in two different synchronized swimming tournaments, here described as Time one (T1) and Time two (T2), were assessed. Results: The results found in the 10 tested pairs (-2. 40 < t(22) < 0. 31) indicate a difference only on the subdimension "Direct Action" (...T1 = 18.57; ...T2 = 19.65) and were statistically different (p < 0. 05), before and after educational intervention. There was high intensity in CO (...T1 = 65.04; ...T2 = 67.61) and a discreet intensity reduction in WO (...T1= 40.52; ...T2 = 40.26) in T2, what may suggest a great tendency to high intensity CO after intervention. Most part of the athletes reported a better efficiency perception influenced by the verbal intervention in T2. Conclusion: Although it is not possible to accredit these results only to the educational intervention, we consider that programs as this may contribute to the usage of cognitive and behavioral strategies once they provide a larger resources repertoire the athletes.

The purpose of this study was to analyze affective and humor responses to high-intensity (HIIT) body work (calisthenic) training. Twenty-six healthy adult men who were recreationally active underwent an acute single session of HIIT body work training. based on 8 sets of 20 sec of all-out supramaximal intensity and 10 sec of passive recovery period. The exercises used were the burpee, jumping jack, mountain climber, and squat and thrust. The subjects responded to the Profile of Mood States (POMS) and a feeling scale before and after the session. After the HIIT body work training, fatigue was higher at the end of the session. There was a gradual reduction in the perception of recovery, especially after the third set. The affective response during the HIIT Whole Body session suffered a gradual reduction of the sensation of pleasure during the series, mainly from the fourth set onwards. The HIIT body work training led to changes in mood levels and progressive reduction in affectivity. [ABSTRACT FROM AUTHOR]

Background: This study aimed to compare exercise intensity through measuring oxygen consumption (VO2), heart rate (HR), and rating of perceived effort (RPE) during an underwater walking at a standardized gait velocity (step x min-1) when wearing swimsuit (SS) or aquatic pants (AP) that increased the drag force Methods: 20 young healthy participants (11 M, 9 F) were recruited; each participant was asked to perform two trials in a random order, one with SS, and the other with AP. Each trial consisted in a 20-minute walk on an underwater non-motorized treadmill at 60, 70, 80, and 90 step x min-1. Results: The total number of steps during the two trials and the walked distance was the same when wearing SS or AP at all rhythms. VO2, HR, and RPE were significantly higher with the use of AP at all gait velocities (P < 0.001). Conclusions: Owing to the larger drag force, AP can be considered as an effective device to increase exercise intensity since the cardiorespiratory response was greater when wearing AP rather than SS.

Background: A few years ago, it was believed that the endothelium was just a membrane separating blood from the outermost layers of blood vessels. However, it has now become recognized as a mediator of vasoconstricting and vasodilatory substances, regulating vessel tone through the information received. The main vasodilatory substance released by the endothelium is nitric oxide, a gas responsible for the inhibition of neovascular growth and platelet aggregation, modulating inflammation and coagulation, and can be released through physical and humoral stimuli. Exercise is considered the best non-pharmacological mechanism in the prevention and treatment of cardiovascular diseases, by promoting greater blood flow, generating blood shear forces on the vessel wall and thus releasing nitric oxide, the most important vasodilator produced by the endothelium. Objective: Verify the effects of aerobic exercise on the endothelium. Methods: We reviewed the studies that evaluated the effects of aerobic exercise and its intensities on the endothelium. Results: According to the studies reviewed in this research, impaired endothelial function improves through aerobic training, whether low, moderate or high intensity. Conclusion: Physical activity, specifically aerobic exercise is an important tool in the production of nitric oxide, responsible for blood vasodilation, inhibition of platelet aggregation among other symptoms of endothelial dysfunction.

Background: Physical training based on body weight was practiced by the Roman military in ancient Rome. Recently some researchers reintroduced the practice exercises with body weight using interval training high intensity, known as HIIT. Objective: The objective of this review was to identify the main variables used in the high-intensity interval training with body weight and propose a load control strategy for the practice of HIIT with body weight. Method/Design: The search was conducted in MEDLINE, EMBASE, SciELO (Scientific Electronic Library Online), LILACS (Literatura Latino-americana e do Caribe em Ciências da Saúde [Centro Latinoamericano y del Caribe de Información en Ciencias de la Salud]), PUB MED CENTRAL, and Cochrane Central Register of Controlled Trials databases. Results: Based on the data available it is possible to visualize a basic guideline for the elaboration of a program of "HIIT body work" considering the parameters of TL using the "all out" load as internal parameter and the stimulus time, recovery time, total duration of the training session, selection and number of movements per exercise as external training load. Conclusion: From the data available in the literature suggest a basic guideline for the development of a high-intensity interval training program with body weight with all out charge, based on the training of control through the stimulation time, recovery time, total time training in the session and selection of exercises.

Introduction: Aging is characterized by a series of changes and adaptations that occur in the body progressively and irreversibly over the years. One of the consequences of senescence is the deficit of maintaining balance, this fact is explained by the involvement of the visual, somatosensory and vestibular systems. Given this scenario, the use of tools that can minimize these declines is of paramount importance. In recent times a resource that has been investigated is virtual reality, this technique stands out for presenting cognitive, motor and cardiorespiratory demands beneficial to the elderly. Objective: The present study aimed to perform a narrative review on the influence of virtual reality on the rehabilitation of balance in healthy elderly. Methods: A bibliographic survey was carried out in Portuguese and English, in the electronic databases: Pubmed, Lilacs, Pedro, Scielo, Scopus and Cochrone. A temporal limiter was applied from 2010 to 2015. Results: We selected 84 articles, however only five fit the criteria of the research. Despite the different methodologies and sample used, all articles selected showed significant improvement in postural balance after virtual reality therapy. However, a lack of standardization of the research protocols can be observed, making it difficult to reach a precise conclusion regarding the real effects of this technique for the study population. Conclusion: Virtual reality therapy was shown to be effective for the rehabilitation of postural balance in healthy elderly individuals. However, such evidence needs to be further investigated in future studies. [ABSTRACT FROM AUTHOR]
