Tongue forces and handgrip strength in normal individuals: association with swallowing

OBJECTIVES: To describe and correlate tongue force and grip strength measures and to verify the association of these measures with water swallowing in different age groups. METHOD: Tongue force was evaluated using the Iowa Oral Performance Instrument and grip strength using the Hand Grip in 90 normal individuals, who were divided into three groups: young (18-39 years old), adult (40-59 years old) and elderly (above 60 years old) individuals. The time and number of swallows required for the continuous ingestion of 200 ml of water were also measured. RESULTS: A reduction in tongue force and grip strength, as well as an increase in the time required to drink 200 ml of water, were observed with increasing participant age. There was no difference in the number of swallows among the three groups. A correlation was observed between reductions in tongue force and grip strength in the groups of young and elderly individuals. CONCLUSION: There were differences in the measures of tongue force in young, adult and elderly individuals. Greater variations within these differences were observed when repeated movements were performed; in addition, a decrease in strength was associated with an increase in age. The decrease in tongue force among the elderly was offset by the increase in time needed to swallow the liquid. There was an association between the measures of tongue force and grip strength in the different age groups. The results of this study can be applied clinically and may act as a basis for guidelines in healthy or vulnerable elderly populations

Factors Related to Sports Participation in Brazil: An Analysis Based on the 2015 National Household Survey

The academic interest in analyzing the correlates of sports participation in several countries has increased recently. Nevertheless, in developing countries, which do not monitor sportive data, this type of investigation is still scarce. This study aims to analyze socioeconomic, motivational, and supportive factors related to sports participation in Brazil. Data from the 2015 National Household Survey-Supplementary Questionnaire of Sports and Physical Activities are examined. In the survey, 71,142 individuals older than 15 years were interviewed (mean age 43.12 years; 53.83% women and 46.17% men). Logistic regression is used for analyzing the data. Results demonstrate a low participation in sports (23.38%). Sports participation declines with increasing age (2% less per year), increases with higher educational level (graduated 5.9 times more), and males prevail in the sporting context (2.3 times more). The main obstacle to women's participation is the lack of sports facilities, and for men the lack of time and health problems. Men practice sports mainly due to socialization, fun, and competition, and women due to medical recommendation. Soccer was the most practiced sport (28.1%), predominating among men. Public policies on sports promotion for fun and socialization may increase male participation, and investments in sports facilities may increase female participation.info:eu-repo/semantics/publishedVersio

Comportamento ingestivo de novilhos mestiços terminados em confinamento alimentados com borra de soja

Este trabalho objetivou avaliar os efeitos da inclusão da borra de soja no comportamento ingestivo de 30 novilhos mestiços Charolês/Nelore, confinados, com 20 meses de idade e peso médio inicial de 328,3 kg. Cada grupo experimental foi composto por seis animais, distribuídos nos tratamentos: 00; 30; 60; 90 e 120 g de borra de soja por 1000 g de matéria seca na dieta, os quais continham 29,0; 47,3; 66,7; 86,8 e 106,8 g de extrato etéreo, respectivamente. O aumento no nível de inclusão de borra de soja na dieta não interferiu no tempo de alimentação, ruminação e ócio (3,11; 13,33 e 7,55 h, respectivamente). As variáveis número de mastigações por bolo, tempo de mastigação por bolo, número de bolos, número de mastigações diárias e tempo de mastigação total (h/dia) (62; 58; 470; 28978 e 10,65, respectivamente) também não sofreram efeito dos tratamentos. O consumo de matéria seca foi similar, em contrapartida, o consumo de fibra detergente neutro (kg/dia) e a eficiência (g FDN/h) da referida fração apresentaram comportamento linear decrescente com aumento da inclusão de borra. A borra de soja pode ser incluída na dieta de novilhos mestiços confinados até o nível de 120 g por 1000 g de matéria seca sem que haja efeitos negativos sobre as principais variáveis relativas ao comportamento ingestivo
