Background: In 2011, the Colombian government started a nationwide program, Hábitos y Estilos de Vida Saludable (HEVS; Healthy Life Habits), providing free, community-based physical activity classes for individuals across Colombia. This study describes the HEVS program, participant characteristics, and changes in anthropomorphic and health measures following the program. Methods: In this observational study, demographic information, current health status, lifestyle habits, and anthropomorphic measures were collected from adult HEVS participants at baseline and after program completion 11 months later. Changes in anthropomorphic and health measurements after the HEVS program were compared in the same participants using a paired t test and McNemar test, respectively. Results: A total of 56,472 adult participants (86.5% female) enrolled in the HEVS program. The greatest proportion of participants was between the ages of 18 and 34 years. Prior to participating in HEVS, mean body mass index and waist circumference were 26.3 kg/m2 and 85.7 cm, respectively. Postprogram data from 17,145 individuals showed statistically significant decreases in body mass index, waist circumference, and the proportion of patients with self-reported hypertension. Conclusions: The HEVS program successfully engaged a large number of Colombians in physical activity and resulted in significant improvements in their health, demonstrating the effectiveness of a government-supported, community-based physical activity program.

There are numerous ways to overload the scapular stabilizers.
To assess scapular stabilizer activity using the Bodyblade® and other traditional training devices.
Repeated measures analysis of surface EMG data collected from the upper trapezius (UT), lower trapezius (LT), and serratus anterior (SA) during shoulder flexion and abduction using Bodyblade®, cuff weight, and Thera-Band® resistance.
Thirty collegiate athletes (20.0 ± 1.7 years).
Participants performed 10 repetitions of shoulder flexion and abduction.
Main Outcome Measures:
For each movement, normalized root mean square values (NrmsEMG) were computed for each muscle during each repetition under each training condition. Data were analyzed using 3 (condition) × 10 (repetition) repeated measures ANOVAs.
During shoulder flexion and abduction, the NrmsEMG of the UT, LT, and SA were significantly greater when using the Bodyblade® than the Thera-Band® or cuff weight.
The Bodyblade® produces greater scapular activity than traditional resistance techniques.

The burden of depression among Hispanics/Latinos indicates the need to identify factors related to depressive symptoms. This paper examines the relationship of physical activity (PA) and sedentary behavior (SB) with depressive symptoms in Hispanic/Latinos.
The Hispanic Community Health Study / Study of Latinos (HCHS/SOL) is a population-based, cohort study of Hispanic/Latinos in 4 United States metropolitan areas. Objectively measured PA was coded into: sedentary behavior (SB), light-intensity (LPA), moderate-intensity (MPA), and vigorous-intensity (VPA); and the Center for Epidemiological Studies Depression Scale-10 assessed depressive symptoms. Multiple regression analysis utilizing isotemporal substitution, adjusted for relevant covariates, examined PA as predictors of depressive symptoms.
Substitution of 1 hour of SB with VPA resulted in a significant decrease in depressive symptoms (β = –1.215, P = .021). Similar decreases were observed when VPA replaced LPA (β = –1.212, P = .021) and MPA (β = –1.50 P = .034). MPA and LPA were not associated with lower depressive symptoms.
Previous research has focused on the relationship of MVPA on depressive symptoms. Our results suggest these constructs should be examined separately as they may have unique relationships with depressive symptoms. The association of SB with greater depressive symptoms confirms previous reports.
