Isolated and Combined Effects of Sedentary Behaviour and Physical Activity on Muscle Strength in Older Adults: A Prospective Cohort Study.

Aim: We aim the isolated and combined effects of sedentary behaviour exposure time and physical activity levels on muscle strength in older adults.

Design: This prospective observational cohort study, analytical in nature, using exploratory survey methods and physical performance testing. With 5-year longitudinal follow-up (2015-2020).

Prevalence and factors associated with low functional mobility in older adults.

Objective: To analyze the factors associated with low functional mobility in older adults residing in Alcobaça, BA.

Methods: This is an epidemiological survey with a cross-sectional design, conducted in 2015 with 473 older adults (62.4% women; mean age 70.

Investigating academic performance and perceptions of human physiology and exercise physiology courses among undergraduate students of physical education at a Brazilian public university.

Purpose: To compare the academic performance of undergraduate students in physical education who studied exercise physiology before and after studying human physiology and investigate students' perceptions of human physiology and exercise physiology courses.

Methods: This study included 311 undergraduate students pursuing a bachelor's degree in physical education. Participants were divided into two groups: those who had previously attended and completed the human physiology course (group 1, n = 212, 68.

The burden of prolonged sedentary behavior imposed by uberization.

Mobility applications are rapidly growing in cities worldwide due to their convenience and low cost. Mobility applications drivers experience vast flexibility in work hours, often work longer than in fixed-hours jobs, and can constantly transport passengers in their vehicles for up to 12 h; after this, they must go offline for eight consecutive hours before driving again. Nonetheless, drivers have found an easy way around this limitation by switching to other apps and continuing driving.

Effects of relocation of sedentary time and physical activity in older adults with diabetes mellitus.

Objective: To estimate the hypothetical effects of substituting time spent in moderate-to-vigorous physical activity (MVPA) and time spent in sedentary behavior (SB) and their associations with diabetes.

Methods: A cross-sectional study using exploratory survey methods was performed in Alcobaça city in the state of Bahia, Brazil in the year 2015. A total of 473 older adults (aged ≥60 years) participated in the study.

Prevalence of fear of COVID-19, depression, and anxiety among undergraduate students during remote classes.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, undergraduate students were exposed to symptoms of psychological suffering during remote classes. Therefore, it is important to investigate the factors that may be generated and be related to such outcomes.

Objective: To investigate the association between fear of COVID-19, depression, anxiety, and related factors in undergraduate students during remote classes.

Origin of the Fastest 5 km, 10 km and 25 km Open-Water Swimmers-An Analysis from 20 Years and 9819 Swimmers.

In elite pool swimmers competing at world class level, mainly athletes from the United States of America and Australia are dominating. Little is known, however, for the nationality of dominating swimmers in elite open-water long-distance swimming races such as the official FINA races over 5 km, 10 km and 25 km-held since 2000. The aim of this study was to investigate the participation and performance trends by nationality of these elite open-water swimmers.

Physical activity combined with sedentary behaviour in the risk of mortality in older adults.

Objective: To examine the effects of physical activity (PA) and sedentary behaviour (SB), in isolation and combination, on all-cause mortality in older adults.

Methods: Prospective, population-based cohort study. The data were collected from first wave in 2015 and the follow-up continued until 2020.

Knowledge of healthcare professionals about poliomyelitis and postpoliomyelitis: a cross-sectional study.

Background: Postpoliomyelitis syndrome is a clinical condition that can affect poliomyelitis survivors.

Objective: Our aim was to evaluate knowledge of poliomyelitis and postpoliomyelitis syndrome among Brazilian healthcare professionals.

Design And Setting: Cross-sectional study conducted at a Brazilian public higher education institution located in the state of Goiás.

Prevalence and Factors Associated with High Concentration of Prostate-Specific Antigen: ELSIA Study.

Background: Prostate cancer (PC) is the second most common cancer among men, behind only non-melanoma skin cancer, and the main method of screening for PC is the prostate-specific antigen (PSA). To analyze the prevalence and the factors associated with high concentration of PSA in the elderly is essential to understand this outcome, and building strategies to decrease their rates of morbidity and mortality.

Methods: We performed a cross-sectional study with 96 elderly men.

Interval Training Improves Depressive Symptoms But Not Anxious Symptoms in Healthy Women.

Despite important advances in the relationship between exercise and mood disorders, especially regarding moderate-intensity continuous training, there is a lack of information about the chronic effects of interval training protocols. We compared the effects of two different interval training protocols [sprint interval training (SIT) and high-intensity interval training (HIIT)] on depressive and anxious symptoms in healthy women. Thirty-six women were randomly allocated to HIIT (n = 18) or SIT (n = 18) groups and performed 24 training sessions over 8 weeks (thrice a week).
