Ensaio teórico sobre o contributo de exercícios multicomponentes em idosos de Moçambique / Theoretical essay on the contribution of multicomponent exercises in elderly people in Mozambique / Ensayo teórico sobre la contribución de los ejercicios multicomponentes en personas mayores en Mozambique

Este ensaio tem como objetivo abordar o contributo da implementação de Exercício Multicomponente na vida de pessoas idosas residentes em Moçambique (país em desenvolvimento), bem como, confrontar com as ações ligadas à execução das políticas públicas sociais de proteção adstritas a esse grupo populacional. O exercício multicomponente é constituído por um leque de tarefas físicas combinadas recomendadas ao idoso que consiste em atividades que envolvem várias capacidades físicas simultaneamente: aeróbica, treino de marcha, equilíbrio, força, potência e resistência muscular. Para a escrita do ensaio, além das reflexões dos autores, foi realizada uma revisão de literatura, bem como, a discussão de documentos oficiais de políticas públicas em vigor em Moçambique. Ficou patente a necessidade de se incluir os exercícios multicomponentes na rotina dos idosos de Moçambique devido a sua relevância no impulsionamento do controle ou reversão das fragilidades biopsicossociais do idoso.

This essay aims to address the contribution of the implementation of Multicomponent Exercise in the lives of elderly people living in Mozambique (developing country), as well as confronting the actions related to the implementation of public social protection policies for this populational group. Multicomponent exercise consists of a range of combined physical tasks recommended for the elderly, consisting of activities that involve several physical capabilities simultaneously: aerobics, gait training, balance, strength, power and muscular endurance. For the writing of the essay, in addition to the authors reflections, a literature review was carried out, as well as the discussion of official documents of public policies in ruling in Mozambique. The need to include multicomponent exercises in the routine of elderly people in Mozambique became clear due to their relevance in boosting the control or reversal of biopsychosocial weaknesses in the elderly.

Este ensayo tiene como objetivo abordar la contribución de la implementación del Ejercicio Multicomponente en la vida de las personas mayores que residen en Mozambique (un país en desarrollo), así como confrontar las acciones relacionadas con la implementación de políticas públicas de protección social relacionadas con este grupo poblacional. El ejercicio multicomponente consiste en un conjunto de tareas físicas combinadas recomendadas para personas mayores, consistentes en actividades que involucran varias capacidades físicas simultáneamente: aeróbic, entrenamiento de la marcha, equilibrio, fuerza, potencia y resistencia muscular. Para la redacción del ensayo, además de las reflexiones de los autores, se realizó una revisión de la literatura, así como la discusión de documentos oficiales de políticas públicas vigentes en Mozambique. La necesidad de incluir ejercicios multicomponentes en la rutina de las personas mayores en Mozambique se hizo evidente debido a su relevancia para potenciar el control o la reversión de las debilidades biopsicosociales en las personas mayores.

Physical Activity Measured by Accelerometry in Mozambican Older Adult Women Attending a Regular Exercise Program.

Time spent in different Physical Activity (PA) Intensities of 72 Mozambican older adult women (67 ± 7 years old) was assessed by means of triaxial accelerometers for 7 consecutive days, and participants were stratified based on their body mass index, as being normal weight (NW, n = 23); overweight (n = 16); or obese (OB, n = 33). Overall, most daily time was spent in sedentary activities (614 ± 111 min or 69.1%) and light PA (181 ± 56 min or 20.2%). On average, moderate to vigorous PA (MVPA) was performed during 10.6% of the day (93 ± 44 min). Time spent in MVPA was significantly higher in the NW compared to OB category (112.8 ± 51.5 vs. 81.0 ± 36.3; p = .021). The overweight group did not differ in time spent in MVPA when compared to NW and OB group. Overall, 75% of the participants spent more than 60 min a day in MVPA (NW: 83%; overweight: 81%; OB: 67%). Pearson's correlation between body mass index and total MVPA controlling for age was -.39 (p < .001). It was concluded that Mozambican older adult women living in urban and rural areas of Maputo province engaged in relatively high Physical Activity Intensities compared with individuals of similar ages in high-income countries, regardless of their nutritional status.

A cross-cultural study of physical activity and sedentariness in youth from Mozambique and Portugal

Abstract Aim: The purpose of this study was to analyse the effects of age, sex, body mass index (BMI) and country of origin (Mozambique versus Portugal) on physical activity and sedentariness. Methods: Sample size was comprised of 593 adolescents from Mozambique (n=258) and Portugal (n=335), aged 10-15 years old. Height and weight were measured, and BMI was computed; furthermore, subjects were classified in two groups (normal weight and overweight/obese). The mean time (min/day) spent in moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and sedentary activity were assessed using the GT3X Actigraph accelerometer over at least 4 days (1 weekend day) with a minimum of 10 hours/day of monitoring. Multiple regression analysis was done in SPSS 20. Results: A low percentage of Mozambican (3.9%) and Portuguese (4.3%) youth complied with the MVPA recommendations (60min·day-1). However, Portuguese boys spend more time in MVPA. Girls and those with higher BMI spend more time in sedentary activities and less time in MVPA and LPA; older adolescents spend more time in sedentary activities and less time in LPA. There is a significant effect of the country of origin on MVPA, favouring Portuguese youth. Conclusions: Results suggest country differences in MVPA between Mozambican and Portuguese youth - the Mozambicans are less involved in MVPA than the Portuguese, probably reinforcing the undesirable effect of the urbanization process in developing nations.

Results From the Mozambique 2016 Report Card on Physical Activity for Children and Adolescents.

BACKGROUND: This article describes the procedures and development of the 2016 Mozambican Report Card on Physical Activity for Children and Adolescents. METHODS: Following the procedures adopted in 2014 for that year's report card, comprehensive searches on new data related to indicators of physical activity (PA) were done. A committee composed of physical activity and sports specialists graded each indicator consistent with the process and methodology outlined by the Active Healthy Kids Canada Report Card model. RESULTS: Nine indicators of PA were graded. Compared with 2014 there were several differences which were caused by changes in the country as well as a more effective evaluation from the committee. The following grades were assigned: Overall Physical Activity Levels, C; Organized Sport Participation, F; Active Play, D; Active Transportation, C; Schools, D; Community and the Built Environment, F; and Government, F. Sedentary Behaviors and Family and Peers were graded Incomplete due to the lack of available information. CONCLUSIONS: The decline of the PA habits in urban centers reported in 2014 are accentuated and is influencing the rural areas in several ways. At present, there is no strategy or effective action from authorities to reverse this negative trend.

Effect of Different Types of Exercise in HIV + Mozambican Women Using Antiretroviral Therapy.

The aim of this study was to evaluate and compare the effect of two types of exercises interventions on the regularity and health-related physical fitness in HIV-infected individuals who use antiretroviral therapy (ART). A total of 53 HIV+ African women (mean age=39.5±8.4 years) on ART participated in the study. Subjects were randomly divided into 3 groups, namely, formal exercise (FEG), playful exercise (PEG) and control (CG). During 12 weeks, the exercise groups underwent a program of 1-hour duration with a frequency of 3 times a week. The FEG performed a protocol that included 20 minutes of exercise, cycling at 60 % of V̇O2peak, increasing to 75 % and 85 % in the 4th and 8th weeks, respectively, and a muscular endurance circuit consisted of 6 exercises at 15 repetitions per minute (RM). The PEG followed a program consisting of active games. Before and after the intervention the participants were submitted to a clinical evaluation including immunological parameters (CD4+), cardiovascular risk factors, physical fitness and anthropometry. Comparison of somatic variables before and after the program showed no exercise effect. Immunological and cardiovascular variables were also independent of the exercise group. The main effect was found in cardiorespiratory fitness: exercise groups increased significantly in V̇O2peak (FEG=14.7 %; PEG=11.1 %) with no significant differences in CG. The percentage of high attendance was identical between the two groups. It was concluded that there is no contraindication for exercise in this type of population and the beneficial effect was mainly in cardiorespiratory fitness, regardless of the type of exercise performed.
