Alcohol Abstainers

Purpose: To describe physical activity habits, sedentary behavior, and cardiorespiratory fitness levels among alcohol abstainers, hazardous and non-hazardous drinkers. Design: Cross-sectional study with data collected between 2017-19. Setting: Sweden. Subjects: Adults aged 18-65 years (n = 47,559; 59.4% male). Measures: During a routine health assessment, participants answered validated single-item questions regarding: habitual physical activity, structured exercise, and the percentage of time spent sedentary during leisure-time (past 30 days), and completed a 6-minute cycle ergometer test (V02max) to determine cardiorespiratory fitness (CRF). Participants were categorized as alcohol abstainers, non-hazardous drinkers or hazardous drinkers (low/high) based on the Alcohol Use Disorders Identification Test (AUDIT-C) cut-points for men and women. Analysis: Logistic regression models stratified by sex and age. Results: Compared to non-hazardous drinkers, the heaviest drinkers were less physically active (males: OR = 1.38, CI = 1.13-1.67, p = .001; females: OR = 1.41, CI = 1.01-1.97, p = .040) and more sedentary during leisure time (males: OR = 1.94, CI = 1.62-2.32, p = .000; females: OR = 1.62, CI = 1.21-2.16, p = .001). Apart from young females, the heaviest drinkers also did less structured exercise than non-hazardous drinkers (males: OR = 1.22, CI = 1.15-1.51, p = .000; females: OR = 1.43, CI = 1.15-1.78, p = .001). The strongest associations were seen among adults aged 40-65 years (shown here). High-hazardous drinking was associated with low CRF among older males only (OR = 1.19, CI = 1.00-1.41). Conclusion: Middle-aged adults with AUDIT-C scores of ≥6 (women) and ≥7 (men) were less physically active and more sedentary during leisure time and may be appropriate targets for physical activity interventions.

Abstract Background Sedentary behavior (SB) and cardiorespiratory fitness (CRF) are important issues in occupational health. Developing a questionnaire to concurrently assess workers’ SB and CRF could fundamentally improve epidemiological research. The Worker’s Living Activity-time Questionnaire (WLAQ) was developed previously to assess workers’ sitting time. WLAQ can be modified to evaluate workers’ CRF if additional physical activity (PA) data such as PA frequency, duration, and intensity are collected. Methods A total of 198 working adults (93 women and 105 men; age, 30–60 years) completed anthropometric measurements, a treadmill exercise test for measuring maximal oxygen consumption (VO2max), and modified WLAQ (m-WLAQ, which included questions about PA data additional to the original questions). Multiple regression analyses were performed to develop prediction equations for VO2max. The generated models were cross-validated using the predicted residual error sum of squares method. Among the participants, the data of 97 participants who completed m-WLAQ twice after a 1-week interval were used to calculate intraclass correlation coefficient (ICC) for the test–retest reliability analyses. Results Age (r = − 0.29), sex (r = 0.48), body mass index (BMI, r = − 0.20), total sitting time (r = − 0.15), and PA score (total points for PA data, r = 0.47) were significantly correlated with VO2max. The models that included age, sex, and BMI accounted for 43% of the variance in measured VO2max [standard error of the estimate (SEE) = 5.04 ml·kg− 1·min− 1]. These percentages increased to 59% when the PA score was included in the models (SEE = 4.29 ml·kg− 1·min− 1). Cross-validation analyses demonstrated good stability of the VO2max prediction models, while systematic underestimation and overestimation of VO2max were observed in individuals with high and low fitness, respectively. The ICC of the PA score was 0.87 (0.82–0.91), indicating excellent reliability. Conclusions The PA score obtained using m-WLAQ, rather than sitting time, correlated well with measured VO2max. The equation model that included the PA score as well as age, sex, and BMI had a favorable validity for estimating VO2max. Thus, m-WLAQ can be a useful questionnaire to concurrently assess workers’ SB and CRF, which makes it a reasonable resource for future epidemiological surveys on occupational health.

Objective: The aim of this study was to determine whether a Latin dance program with sedentary behavior information would have an impact on physical activity, cardiorespiratory fitness (CRF), and sedentary behavior among older Latinos attending an adult day center (ADC). Method: Participants ( N = 21, 75.4 ± 6.3 years old, Mini-Mental State Examination [MMSE] score = 22.4 ± 2.8) were randomized into a dance or wait-list control group. Participants wore an accelerometer and inclinometer and completed a sedentary behavior questionnaire, and a nonexercise equation was used to calculate CRF. Results: Findings indicate small to medium effect sizes in the desired direction during midpoint of the intervention for physical activity, sedentary behavior–related outcomes, CRF, and self-reported sedentary behavior in the dance group; however; dance participants did not maintain that trajectory for the remaining 2 months of the intervention. Discussion: Future studies may consider implementing behavioral strategies during midpoint of the intervention to encourage participants attending an ADC to maintain physical activity and sedentary behavior changes.

Abstract Physical activity and sedentary behavior promote opposite effects on overweight and obesity, in adolescents; however little is known of their combined impact on these outcomes. We aimed to investigate if there were any associations between overweight, and physical activity level, cardiorespiratory fitness, and sedentary behavior, both as isolated variables and in combination. Data of 1,015students from two public and four private schools from the metropolitan area of Rio de Janeiro, Brazil were analyzed. Overweight was classified according to body mass index, whereas physical activity level was assessed by the International Physical Activity Questionnaire (IPAQ), cardiorespiratory fitness by a 9-minute test (T9), and sedentary behavior by a self-completed questionnaire, considering the time spent watching television as the main indicator. Associations were examined by binary logistic regression analysis. Odds ratios (ORs) and 95% confidence intervals (95%CIs) were used to measure the magnitude of the associations. IBM SPSS Statistics version 20 was used for all statistical analyses. Adolescents with poor cardiorespiratory fitness (OR=3.71; 95%CI=1.30-10.6) and a high degree of sedentary behavior (OR=1.73; 95%CI=1.24-2.42) had a bigger chance of being overweight. However the combination of these two categories in the same individual was not statistically associated with overweight. The study indicates that both sedentary behavior and poor performance on cardiorespiratory fitness test are significantly independent associated with overweight in adolescents.

The Impact

The influence of a complex of traditional qigong exercises, used in conjunction with classical methods of physical education, has been investigated in order to identify trends in changes in the indicators of general physical condition, to monitor a number of medical tests (general blood test, biochemical blood test, pulse, pressure). The work involved 619 (six hundred and nineteen) students of male main groups, of which 550 people were the experimental group and 69 were the control group. Scientific work was carried out on the basis of the Ufa State Petroleum Technical University in an annual period, from September 21, 2019 to February 20, 2020. The purpose of this study is to study the influence of this technique on increasing the level of the functional state of students, improving the process of physical education, the impact on the health of USPTU students attending classes. A similar study was described in his scientific publications by V.V. Vinantova (1996) and L.R. Kalimullina (2005). Yu.A. Petrova in her works (1992) noted that the volume of circulating blood, its components and the total number of hemoglobin increases in students under the influence of training. Metabolism is at the forefront of the changes that occur as a result of exercise. Accompanied by the released energy and the synthesis of ATP, the rate of catabolic processes in the body increases [1, 2]. The concentration of blood corpuscles increases when part of the plasma leaves the vascular bed and goes into the intercellular fluid due to physical exertion. First of all, this applies to red blood cells that transport oxygen. Under such conditions, the same volume of blood is able to carry more oxygen to working muscles [3]. The disadvantage of reducing plasma volume is an increase in blood viscosity, which makes it difficult for the heart to work. At the end of the 19th century, an increase in the number of leukocytes in the blood after exercise was found - myogenic leukocytosis. A.P. Egorov in his works (1926) showed that myogenic leukocytosis is accompanied by an increase in the number of white blood cells. The last phase may be accompanied by a sharp increase or a sharp decrease in the number of leukocytes to the physiology of the norm [4]. A change in the level of lymphocytes in the blood due to physical activity can be defined as one of the prognostic signs showing the level of adaptation of the body to physical activity
