Effects of Three Resistance Exercise Orders on Muscular Function and Body Composition in Older Women.

The purpose of the present study was to compare the effects of three resistance exercise orders on muscular strength, body composition, and functional fitness in trained older women. Forty-five women (aged ≥60 years), after performing 12 weeks of a pre-conditioning resistance-training program were randomly assigned in one of the following groups that performed the exercises in the following orders: multi-joint to single-joint order (MJ-SJ, n=15), single-joint to multi-joint order (SJ-MJ, n=15), and alternating between upper and lower body order (ALT, n=15). Specific training intervention lasted 12 weeks (3x/week) and was composed of eight exercises performed in three sets of 15/10/5 repetitions, with increasing load through the sets.

[Agreement between two cutoff points for physical activity and associated factors in young individuals].

Objective:: To analyze the agreement between two cutoff points for physical activity (300 and 420 minutes/week) and associated factors in youth.

Methods:: The study enrolled 738 adolescents of Londrina city, Paraná, Southern Brazil. The following variables were collected by a self report questionnaire: presence of moderate to vigorous physical activity, gender, age, father and mother education level, with whom the adolescent lives, number of siblings, physical activity perception, participation in Physical Education classes, facilities available to physical activity practice and sedentary behavior.

[Malnutrition and its association with activities during leisure time among adolescents].

The scope of this study is to analyze the prevalence of malnutrition among adolescents in two Brazilian cities and to analyze possible associations with leisure-time physical activity. 2782 adolescents ranging from 10 to 17 years of age enrolled in public and private schools from a city in the southeastern and another in the southern region participated in the study. Body weight and height were duly recorded.

Characteristics of family nucleus as correlates of regular participation in sports among adolescents.

Objectives: To estimate the relationship between family nucleus and sport practice among adolescents.

Methods: A school-based cross-sectional study carried out with 1,752 Brazilian adolescents (812 male and 940 female), aged 11-17 years. Characteristics of the family nucleus (parental education, socioeconomic status and number of siblings) and sport practice (≥240 min/week) were assessed by questionnaires.

Nutrition-related habits and associated factors of Brazilian adolescents.

Objectives: To investigate the nutrition-related habits (NRH) of Brazilian adolescents and evaluate the associations with risk factors.

Methods: Cross-sectional school-based was carried out among high school adolescents aged 14-18 years (n = 1,759) from public and private schools from two cities. The NRH were investigated by the weekly consumption of vegetables, fruit, sweet food and fried food.

Evaluation of the Omron MX3 Plus monitor for blood pressure measurement in adolescents.

This study analyzed the accuracy/agreement of the Omron MX3 monitor on 165 adolescents. Blood pressure was measured by the automatic monitor connected in Y with the mercury column (three consecutive and simultaneous measures). The independent measures were analyzed, and the mean differences between systolic and diastolic measures for both methods were calculated and compared with British Hypertension Society (BHS) and Association for the Advancement of Medical Instrumentation (AAMI) criteria.

Association between regular participation in sports and leisure time behaviors in Brazilian adolescents: a cross-sectional study.

Background: The belief that adolescents engaged in sports increase their overall physical activity level while simultaneously decreasing physical inactivity has been the foundation of many intervention programs in developing countries. The aim of this study was to analyze the association between regular participation in sports and both active behaviors and TV viewing during leisure time.

Methods: A total of 1752 Brazilian adolescents (812 = male and 940 = female) participated in this study.

The use of bioelectrical impedance to detect excess visceral and subcutaneous fat.

Objective: To analyze bioelectrical impedance performance in detecting the presence of excess visceral fat and overweight/obesity in young Brazilians and how its values are related with them.

Methods: Study sample consisted of 811 adolescents of both genders (11 to 17 years of age). Nutritional status was determined based on triceps skinfold thickness (TSF), relative body fat (bioelectrical impedance), and excess visceral fat as determined by waist circumference.
