Background: Using preferred music during the exercise series was a differentiated way to increase muscle performance and fatigue slowdown, increasing the number of repetitions in these exercises. Despite of some studies present the effects of music, there is still a little music influence in strength training. Objectives: Verify the music effect on the strength performance in young adults, and the relation with the preferences of muscular grouping according to gender. Methods: a cross-sectional, controlled and crossover study was carried out with 20 physically active young adult participants (10 men). After previous laboratory evaluations, they underwent two exercise sessions, one experimental, where the participant performed 3 maximum series of exercises Barbell Curl and Leg Extensor seat listening to songs of their own choosing and another control session without music, adopting the series with greater repetition in each exercise for analysis. A minimum interval of 48 hours was adopted between each session. The protocol order (i.e. with music or without music) was made by the raffle. In the sessions, participants were asked to perform the maximum number of repetitions at 80% of the load determined in the laboratory. Results: The use of their preferred music significantly increased the number of repetitions in the two exercises, however, the preferences for muscular clusters characterized by the genders proved to be a determining variable. Conclusion: With the increasing of repetitions it was possible to observe an ergogenic resource to increase the performance in strength training, thus, a differentiated performance pattern was found between men and women in arm exercises when they use music.

ABSTRACT Introduction It is known that strength training brings improvements in health and sports performance by causing muscle hypertrophy and increased strength, as well as modifying some hemodynamic and physiological factors. Several strength training methodologies have been developed, one of which is vascular occlusion. There are few studies with large muscle groups due to poor adherence to the training style and the fact that vascular occlusion of large muscle groups is more difficult. Objective To verify and compare the hemodynamic effects of exercise with and without vascular occlusion in different muscle groups. Methods Quantitative crossover study, with cross-sectional and field procedures. The sample consisted of 10 physically active healthy male and female subjects between 18 and 30 years of age. With the cross-over design, all the volunteers participated in 3 groups: intervention with vascular occlusion, intervention without vascular occlusion and the control group. Results Overall, lactate and cholesterol remained elevated after 15 minutes of recovery and blood glucose and blood pressure did not vary among the groups. Conclusion Vascular occlusion training is an effective method for manipulating hemodynamic variables. Evidence level II; Clinical study.

Abstract Objective: To analyze anthropometric, muscle performance and foot trajectory determinants of stride length (SL) during walking at a comfortable pace among self-reliant community-dwelling elderly persons in Talca, Chile. Method: A total of 63 self-reliant elderly persons participated in this observational and cross-sectional study. They were characterized by the anthropometric measures of mass, height and body mass index. Dorsiflexor muscle strength performance (DF-MS) and rate of force development were quantified. Finally, the elderly persons were asked to walk comfortably around a 40 meter elliptical circuit, using determined SL and maximum foot clearance (MaxFC) and minimum foot clearance (MFC) trajectory parameters. The SL determinants were evaluated by calculating the coefficient of determination (r2) considering a level of significance of p≤0.05. Results: The anthropometric variables demonstrated significant correlations (r>0.41) with the explanation of SL remaining incipient (r2<0.20). Muscle performance, meanwhile, was significantly correlated (r>0.52), with DF-MS standing out (r2=0.342). MaxFC represented a significant explanation for the data (r2=0.396), while the low correlation of MFC was not significant (r=0.24, r2=0.058). Conclusion: MaxFC and DF-MS are determinants of SL in self-reliant elderly Chileans. It is proposed that gait parameters could be normalized in accordance with trajectory and muscular performance.

BACKGROUND There have been challenges in designing effective behaviour-change interventions, including those that promote physical activity. One of the key reasons is that many of those systems do not account for individuals’ characteristics and their psychological differences, which affect their approach toward adopting target behaviour. For decades, tailoring has been used as a common technique to effectively communicate health-related information to persuade people to follow a healthier living. However, its use in the design of persuasive technologies has not been adequately investigated. OBJECTIVE The objective of this research is to explore the effects of tailoring when it is grounded in Higgins’ regulatory focus theory. METHODS A combination of cross-sectional and longitudinal studies has been proposed to examine how individuals’ intention to become more physically active would be affected by receiving health messages that may or may not match their self-regulatory orientation. The research would also subjectively, as well as objectively, measures the changes in individuals’ physical activity level. RESULTS The anticipated completion date for the consequent studies is December 2016. CONCLUSIONS In this article, the importance of refining message-framing research questions and a stepwise approach to develop an efficient experimental design to examine a new tailoring strategy is discussed. A set of small studies is proposed that would inform the best approach to design the principal experiment. The findings of principal experiment will provide a deeper insight into the relationship between regulatory-focus theory, persuasive message construction, and individuals’ physical activity behaviour.

Caffeine is a food supplement widely consumed by athletes, but it has not been established. So far, the veracity of their labeling in terms of the dosage and cause/effect relationship aimed at the consumer. The aim is to analyze the health claims and the dosage presented on the labeling of caffeine supplements and to evaluate if they follow the European Food Safety Authority (EFSA) and international criteria. A descriptive cross-sectional study of a sample of caffeine supplements was carried out. The search was done through the Amazon and Google Shopping web portals. In order to assess the adequacy of the health claims, the guidelines of reference established by European Food Safety Authority were compared to the Academy of Nutrition and Dietetics, International Olympic Committee, and Australian Institute of Sport guidelines; in addition, recent systematic reviews were addressed. A review of labels of 42 caffeine supplements showed that, in less than 3% of the products were the health claims supported by the recommendations and by the labeled quantity of caffeine. The claims that fully complied the recommendations were, “improves or increases endurance performance”, “improves strength performance”, or “improves short-term performance”. In most cases, the recommended dosage was 200 mg/day for these products, which is the minimum for the caffeine effects to be declared. The rest of the health claims were not adequate or need to be modified. Most of the health claims identified indicated an unproven cause and effect, which constitutes consumer fraud, and so must be modified or eliminated.

Background: No specific physical activity guidelines are available for women in multiple pregnancy. Aim of the study was to assess the knowledge and experience of women regarding physical activity during their latest twin pregnancy. Methods: A cross-sectional study including women after a twin delivery was conducted in Poland. A questionnaire was distributed in 2018 via web pages and Facebook groups designed for pregnant women. Results: 652 women filled out the questionnaire completely. Only 25% of women performed any physical exercises during twin gestation. The frequency of preterm delivery was similar in physically active and non-active participants. 35% of the respondents claimed to have gained information on proper activity from obstetricians during antenatal counselling while 11% claimed to be unable to identify the reliable sources of information. 7% of women admitted to feel discriminated by social opinion on exercising during a twin pregnancy. Conclusions: The population of women with a twin gestation is not sufficiently physically active and is often discouraged from performing exercises during gestation. Therefore, it is crucial to inform obstetricians to recommend active lifestyle during a twin gestation and to provide reliable information on physical activity to pregnant women. Further research on this topic is necessary in order for obstetric providers to counsel women on appropriate exercise with a twin pregnancy.

Background: This study aimed to identify the factors associated with the quality of life of young workers of a Social Work of Industry Unit. Methods: This was a cross-sectional study conducted on 1270 workers. Data were collected using a digital questionnaire built on the KoBoToolbox platform that included the EUROHIS-QOL eight-item index to assess quality of life. Demographic, socioeconomic, behavioral, and clinical variables were considered explanatory. The associations were analyzed using the ordinal logistic regression model at a 5% significance level. Results: Men and women had a mean quality of life of 31.1 and 29.4, respectively. Workers that rated their health as “very good” had an odds ratio of 7.4 (95% confidence interval (CI) = 5.17–10.81), and those who rated it as “good” had an odds ratio of 2.9 (95% CI = 2.31–3.77). Both these groups of workers were more likely to have higher levels of quality of life as compared to workers with “regular”, “poor”, or “very poor” self-rated health. Physically active individuals were 30% more likely to have higher levels of quality of life (odds ratio = 1.3; 95% CI = 1.08–1.65). After adjusting the model by gender, age group, marital status, socioeconomic class, self-rated health, nutritional status, and risky alcohol consumption, the odds ratio of active individuals remained stable (odds ratio = 1.3; 95% CI = 1.05–1.66). Conclusions: In the present study, self-rated health, physical activity, and gender were associated with young workers’ quality of life.

IntroductionFalls/near falls are the second leading cause of hospitalisation and outpatient visits among US Army soldiers. While numerous studies have evaluated fall-related or near fall-related injuries among elderly adults, few have evaluated this association among young adults. The objective of this study is to describe the characteristics and risk factors associated with fall-related or near fall-related injuries among male US Army soldiers.MethodsThis is a cross-sectional study of male US Army Airborne Division soldiers (n=5187). Electronic surveys captured demographic, lifestyle, physical training (PT), fitness and injury data during spring/summer of 2016. Multiple logistic regression was used to identify independent risk factors of fall-related or near fall-related injuries, adjusting for potential confounders.ResultsPrimary findings indicated that activities and risk factors associated with fall-related or near fall-related injuries among soldiers included younger age (≤35 years), holding a job that required minimal lifting activities, slower 2-mile run times and not running during personal PT.ConclusionsThe findings from this study suggest that male US Army soldiers and other physically active men may benefit from (1) obtaining and/or maintaining higher aerobic endurance and muscular strength, and (2) training focused on preventing fall-related injuries during PT, road marching and sports/recreational activities. Moreover, prevention strategies and education should further target younger soldiers (≤35 years old), as younger age is not modifiable.

Low- and moderate-impact physical activity (PA) is associated with the prevention of urinary incontinence (UI). The objective of the cross-sectional study presented herein is to analyze the factors associated with UI in physically older active women who participate in senior community groups. The variable UI was measured by the International Consultation Incontinence Questionnaire Short Form (ICIQ-SF). Socioeconomic variables were also collected, along with data on life habits and clinical history. The multivariate analysis employed Poisson’s Regression with robust variance for factors associated with UI. Of the 106 participants evaluated, 54.7% presented UI, of which stress incontinence was more frequent, with 40.6%. UI presented a statistically significant association with dizziness/loss of balance during Activities of Daily Living (ADL) (prevalence ratio-PR 1.48; 95% CI 1.06–2.07) and nocturia (PR 1.63; 95% CI 1.05–2.55). Despite PA being a protection factor, UI presented an elevated prevalence in the older population, and therefore, other biological, social, and cultural aspects could also contribute to the occurrence of UI in this age group. Moreover, physically active older women with UI presented nocturia and dizziness/loss of balance during ADL, regardless of education levels and the number of births. These findings can help improve multi-professional programs aimed at promoting, preventing, and managing UI in the public.

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.
