Logic model of the Recreovía: a community program to promote physical activity in Bogota / Modelo lógico da Recreovia: um programa para a promoção da atividade física em Bogotá

This study aimed to develop the logic model of the Recreovía program in Bogota, Colombia. The logic model was developed based on the manual of the Center of Disease Control and Prevention (CDC), with indicators of resources, activities and short- and long-term results. Mixed methods were used for data collection and analysis. Human, physical and financial resources, as well as collaborators of the program, were identified, besides the activities defined according to the program aims. In conclusion, the program emphasizes the processes and actors for their operation and maintenance, and recognizes future challenges for physical activity promotion in Bogota.

Using observational methods to evaluate public open spaces and physical activity in Brazil.

BACKGROUND: Open public spaces have been identified as important facilities to promote physical activity (PA) at the community level. The main goals of this study are to describe open public spaces user's characteristics and to explore to what extent these characteristics are associated with PA behavior. METHODS: A system of direct observation was used to evaluate the PA levels on parks and squares (smaller parks) and users's characteristics (gender and age). The 4 parks and 4 squares observed were selected from neighborhoods with different socioeconomic status and environmental characteristics. The settings were observed 3 times a day, 6 days per week, during 2 weeks. RESULTS: More men than women were observed in parks (63.1%) and squares (70.0%) as well as more adults and adolescents than older adults and children. Users were more physically active in parks (men = 34.1%, women = 36.1%) than in squares (men = 25.5%, women 22.8%). CONCLUSIONS: The characteristics of public open spaces may affect PA in the observed places. Initiatives to improve PA levels in community settings should consider users' characteristics and preferences to be more effective and reach a larger number of people.

Comportamento da força muscular após três semanas de destreinamento em adultos jovens / Strength muscle behavior after three weeks detraining in young adults

O objetivo deste estudo foi verificar o comportamento da força muscular após três semanas de destreinamento em adultos jovens. Dez homens (22,5±5,5 anos) ativos, saudáveis e experientes no treinamento de força realizaram o teste de 10RM nos exercícios leg press, supino reto e rosca scott, pré e pós um período de três semanas de destreinamento. Para a análise dos dados foi utilizado o teste não paramétrico de Wilcoxon, o nível de significância mantido em 5% e as análises realizadas no software SPSS 15.0. Não foi verificada diferença significativa em nenhum dos exercícios no pré e pós teste (leg press: pré 294,4±46,7, pós 316,7±51,7 kg; supino reto: pré 58,5±8,1, pós 59,4±9,9 kg; rosca scott: pré 31,2±2,3, pós: 31,8±3,9 kg). Entretanto, no leg press e rosca scott houve um incremento da força de 7,8 e 3,2%, respectivamente. Pode-se concluir que não existe alteração na força muscular após três semanas de destreinamento.

The aim of this study was to investigate the behavior of the muscle strength after three weeks of detraining in young adults. Ten active, healthy and experienced in strength training men (22.5±5.5 years), performed 10RM test in leg press, bench press and arm curl exercises, before and after a period of three weeks of detraining. Data was analyzed with nonparametric Wilcoxon test, the significance level was maintained at 5% and the analysis performed in SPSS 15.0. There was no significant difference in exercises in pre and post test (leg press: pre 294.4±46.7, post 316.7±51.7 kg, bench press: pre 58.5 ± 8.1, post 59.4 ± 9.9 kg; arm curl: pre 31.2±2.3, post: 31.8±3.9 kg). However, there was a strength increase of 7.8 and 3.2% in the leg press and arm curl respectively. In conclusion, was verified that no change in muscle strength happened after three weeks of detraining.
