RESUMEN
COVID-19 is an infectious and contagious disease, caused by the SARS-CoV-2 virus. Due to the rapid spreading of the virus and its lethal consequences, the WHO declared a pandemic. One of the main strategies to treat and prevent the spreading was the stay home safe, a social isolation situation that was accompanied by the closing of fitness gyms, city parks and facilities proper to exercise. This context promoted an increase in home fitness programs and in the search for information online regarding exercise and health. So, the objective of this study was to understand the effects of the pandemic on physical activity behavior and online information search regarding exercise programs. Data collection was through a google forms questionnaire, all procedures were approved by the University ethics committee and we collected data from 1065 participants. Our results showed that the participants main behavior was maintained, 80.7% of our sample were active before the pandemic and only 9.7% of this group stopped being active. On the other hand we registered 7% of participants that started exercise after the pandemic installation. Information about exercise was searched outside social media by 49.6% of the participants with 32.5% using social media. 56.1% would look only for professional advice, interestingly 11.4% of the participants were active without any kind of advice. We concluded that Covid-19 pandemic installation affected negatively the population physical activity behavior and increased awareness about the importance of exercise as a health strategy.
RESUMEN
This study aimed to compare the practice of physical activity in groups of people with chronic diseases with and without medication, before and during the pandemic. 298 Brazilian individuals with chronic non-communicable diseases such as cardiovascular, metabolic / endocrine, respiratory, orthopedic, gastrointestinal diseases, anxiety and depression were separated into two groups: with and without medication. A questionnaire with 14 questions was applied, tracing the behavioral profile in relation to physical exercises before and during isolation, interpreted through descriptive analysis, and the groups were compared through Mann-Whitman's statistics. The drop in the percentage of active individuals with or without medication occurred when comparing the scenarios before and during quarantine. However, the difference in the prevalence of active individuals between the groups was significant, showing that the group with medication remained more active. The fear of contamination, the measures of distance and the lack of adherence of the population to classes by videoconference reduced the frequency of physical activities in the general sample population. However, people who used medication showed greater concern about the practice of physical activity to optimize treatment. The isolation period had a negative impact on the practice of physical activity, regardless of the presence of some chronic disease or the use of medication.
RESUMEN
INTRODUCTION: Although the rapid weight loss process is undertaken by combat sports athletes very often, the impact of this practice on cardiovascular health is not fully understood. OBJECTIVE: To verify the effects of the rapid weight loss process undertaken by combat sports athletes on hemodynamic parameters, cardiovascular autonomic modulation and mood state. METHODS: Eight male fighters (21.62±1.49 years, 71.25±3.54 kg, 1.74±0.03 cm) were assessed in the city of São Paulo. The subjects had 5.37±0.77 years of practice and were training 5.75±0.45 days per week, for 3.05±0.69 hours per day. The athletes were assessed on 2 occasions: 14 days before and 1 day before official weigh-in. Weight, height and bioimpedance were used for body composition analysis. Mood state was assessed using the Brums Mood Scale. Blood pressure was measured at rest with a digital meter. Cardiovascular autonomic modulation was obtained through an analysis of heart rate variability recorded for 25 minutes at rest. The Student's t-test for dependent samples was used for comparison between time points. Values of p<0.05 were considered significant. RESULTS: No differences in body composition were observed between the time points evaluated. After the weight loss strategy, increases in mood state parameters related to anger, vigor and fatigue categories were observed. Blood pressure did not change between the time points evaluated. However, an increase in heart rate associated with greater sympathetic modulation was observed after the weight loss strategy. There were no differences in autonomic modulation parameters representing parasympathetic activity. CONCLUSIONS: The study provided evidence of a higher cardiovascular risk in athletes as a result of this rapid weight loss practice, which is very concerning since combat sports athletes repeat this process several times during their lives. Level of Evidence IV; Study type: Case series
INTRODUÇÃO: Apesar de o processo de perda ponderal rápida ser realizado por atletas de esporte de combate com muita frequência, os impactos dessa prática sobre a saúde cardiovascular não estão totalmente esclarecidos. OBJETIVO: Verificar os efeitos do processo de perda ponderal rápida realizado pelos atletas de esportes de combate sobre parâmetros hemodinâmicos, modulação autonômica cardiovasculares estado de humor. MÉTODOS: Foram avaliados oito lutadores do sexo masculino (21,62 ± 1,49 anos, 71,25 ± 3,54 kg, 1,74±0,03 cm) na cidade de São Paulo. Os sujeitos tinham 5,37 ± 0,77 anos de prática, treinavam 5,75 ± 0,45 dias por semana, durante 3,05 ± 0,69 horas por dia. Os atletas foram avaliados em duas oportunidades: 14 dias e 1 dia antes da pesagem. Foram realizadas avaliações de massa corporal, altura e bioimpedância para análise da composição corporal. O estado de humor foi avaliado pela da escala de humor de Brums. A pressão arterial foi aferida em repouso com medidor digital. A modulação autonômica cardiovascular foi obtida pela análise de variabilidade da frequência cardíaca gravada durante 25 minutos em repouso. Para a comparação entre os momentos, foi utilizado teste t de Student para amostras dependentes. Os valores de p < 0,05 foram considerados significativos. RESULTADOS: Não foram observadas diferenças na composição corporal entre os momentos avaliados. Após a estratégia de perda ponderal, foram observados aumentos dos parâmetros de humor relacionados às categorias raiva, vigor e fadiga. A pressão arterial não se alterou entre os momentos avaliados. Entretanto, verificou-se aumento da frequência cardíaca associado à maior modulação simpática após a estratégia de perda ponderal. Os parâmetros de modulação autonômica representativos de atividade parassimpática não apresentaram diferenças. CONCLUSÕES: Houve maior risco cardiovascular nos atletas em decorrência dessa prática de perda ponderal rápida, o que é muito preocupante, tendo em vista que os atletas de esportes de combate repetem esse processo várias vezes durante a vida. Nível de Evidência IV; Tipo de estudo: Série de casos.

The present study aimed to investigate the effects of a 6-month multicomponent exercise program (MCEP) on functional, cognitive, and hemodynamic parameters of older Type 2 diabetes mellitus (T2DM) patients. Moreover, additional analyses were performed to evaluate if T2DM patients present impaired adaptability in response to physical exercise when compared to nondiabetic volunteers. A total of 72 T2DM patients and 72 age-matched healthy volunteers (CG) were recruited and submitted to functional, cognitive, and hemodynamic evaluations before and after six months of a MCEP. The program of exercise was performed twice a week at moderate intensity. Results indicate T2DM and nondiabetic patients present an increase in mobility (i.e., usual walking speed) after the MCEP. However, improvements in maximal walking speed, transfer capacity, and executive function were only observed in the CG. On the other hand, only T2DM group reveals a marked decline in blood pressure. In conclusion, data of the current study indicate that a 6-month MCEP improves mobility and reduce blood pressure in T2DM patients. However, maximal walking speed, transfer capacity, and executive function were only improved in CG, indicating that T2DM may present impaired adaptability in response to physical stimulus.

ABSTRACT Introduction: Aging is inevitable and irreversible, but with the advancement of technology, life expectancy is increasing every year, bringing proposals for various interventions to improve the quality of life. One such intervention is physical exercise programs. Objectives: To investigate the impact of multicomponent training in circuits on functional autonomy parameters in elderly women. Methods: Elderly were recruited and distributed in two groups: trained (N = 16) and non-trained (N = 15). Those in the trained group performed 75-minute training sessions twice a week over a 56-week period. The resistance training included upper and lower limbs with a relative intensity of 70% of 1RM, exercises using body weight, stretching and specific tasks for agility, performed in a circuit form and totaling three passages. Participants underwent functional autonomy (FA) assessment by the protocol of the Latin American Developmental Group for Maturity, the 6-minute walk test (T6M), and the sit-and-reach (SR) test. Results: The trained group had a significant decrease in body weight (p=0.02) and body mass index (p=0.015). Significant improvements (p=0,009) were also observed in FA, SR, and T6M after the intervention Compared with the untrained group, the trained group also obtained significant differences in all functional parameters analyzed. Conclusion: A long-term multicomponent training program conducted on a circuit and applied twice a week was enough to improve multiple components of the functional autonomy of elderly women.

RESUMEN
Aim. Utilizing a cross-sectional case control design, the aim of this study was to evaluate the functional fitness and self-reported quality of life differences in older people diagnosed with knee osteoarthrosis (O) who participated in health promotion groups. Methods. Ninety older women were distributed into two groups: control without O of the knee (C, n = 40) and a group diagnosed with primary and secondary knee O with grade II or higher, with definite osteophytes (OA, n = 50). Functional fitness was evaluated by specific tests, and the time spent in physical activity and quality of life was evaluated by the IPAQ and WHOQOL (distributed in four domains: physical: P, psychological: PS, social: S, and environmental: E) domain questionnaires. Results. No differences were found between ages of groups (C: 66 ± 7; OA: 67 ± 9; years). The values of the chair stand test (rep) in the OA (13 ± 5) group were different when compared to C group (22 ± 5). For the 6-minute walk test (meters), the values obtained for the C (635 ± 142) were higher (P < 0.01) than the OA (297 ± 143) group. The time spent in physical activity (min) was greater (P < 0.001) in the control (220 ± 12) group compared to OA (100 ± 10) group. Higher values (P < 0.001) in all domains were found in the C (P: 69 ± 16, PS: 72 ± 17, S: 67 ± 15, E: 70 ± 15) group compared to OA (P: 48 ± 7, PS: 43 ± 8, S: 53 ± 13, E: 47 ± 14) group. Conclusion. Our data suggests that knee O, in older women, can promote a decline in time spent performing physical activity and functional fitness with decline in quality of life with an increase in sitting time.
