    Background

     Non-communicable diseases (NCDs) are responsible for 60% of global deaths. Of these NCD-attributable deaths, about 80% are in low- to middle-income countries (LMICs). The role of exercise in major NCDs is evident; however, popular and cost-effective aerobic modes of exercise, such as walking, consistently do not meet minimum intensity guidelines for health improvement. Interestingly, low-cost resistance training (using callisthenics, Pilates, elastic tubing, etc.) has proven equally effective to conventional resistance training using weight machines in improving several health parameters related to NCDs, although their effectiveness in LMICs is not as well documented as in high-income countries (HICs).

    Objectives

     This review aimed to examine low-cost approaches of resistance training to health promotion, NCD risk reduction, and NCD rehabilitation/management to mitigate the epidemic of NCDs in lower-resource settings.

    Methods

     An electronic search was performed on the following databases from inception until December 2019: PubMed/Medline, Sport Discuss, Embase, Science Direct, Current Contents, CISTI Source, Google Scholar, Cochrane Library, Cochrane Database of Systematic Reviews, CINAHL EBM Reviews, and international e-catalogues.

    Results

     Data on resistance training provision cost in low-resource settings indicates that it is not reasonable to use this mode of training in low-resource settings in the same way as it is used in high-resource ones. This review summarized some strategies which can be employed to ensure the delivery of all core resistance training components in low-resource settings. The data suggests that resistance training be adapted for delivery in non-clinical settings in LMICs.

    Conclusions

     Program design variables of resistance training are similar in low- and well-resourced settings. However, only individuals with low-risk will be able to perform exercise without adverse consequences in home-based settings. Health care practitioners in LMICs should take an active role in promoting resistance training when promoting health, reducing NCD risk, and NCD rehabilitation.

    Background

     Studies have demonstrated that young adults, especially in low- to middle-income countries, are increasingly susceptible to unfavorable alterations in body composition during their transition from adolescence to adulthood. This places young adults at an increased risk for numerous chronic diseases, such as cardiovascular, and/or pulmonary diseases.

    Objectives

     This study aimed to determine if concurrent aerobic and resistance calisthenic training could reduce cardiopulmonary disease risk in young adults in a low resource setting.

    Methods

     Thirty young adult males were randomly assigned to either a six-week non-exercising control group (NON) or concurrent aerobic or resistance training group (CON) that engaged in three, non-consecutive, 60-minute exercise sessions using a combination of 4 - 5 progressive resistance training exercises for two sets of 15 - 20 repetitions and 30 minutes of aerobic exercises at a rating of perceived exertion of 9 - 15. This study assessed anthropometry (body mass, stature, body mass index waist-to-hip ratio, waist-to-stature ratio, sum of skinfolds, percentage body fat, fat mass, fat free mass and conicity index) and lung function (forced vital capacity (FVC), forced expired volume in one second (FEV1), forced expiratory volume in one second/forced vital capacity ratio (FEV1/FVC), peak expiratory flow (PEF), maximal expiratory flow at 75% (MEF75%), maximal expiratory flow at 50% (MEF50%) and maximal expiratory flow at 25 (MEF25%).

    Results

     Concurrent training resulted in significant (P ≤ 0.05) improvements in waist-to-hip ratio (0.94 ± 0.04 to 0.92 ± 0.05; P = 0.042), fat free mass (57.46 ± 9.16 to 58.21 ± 8.65 kg; P = 0.018), percentage body fat (14.56 ± 5.96 to 13.24 ± 5.77%, P = 0.006), fat mass (10.22 ± 5.31 to 9.29 ± 5.17 kg; P = 0.008), sum of skinfolds (96.22 ± 35.64 to 87.67 ± 32.15 mm; P = 0.004), PEF (5.06 ± 2.04 to 6.57 ± 2.51 L; P = 0.018), MEF75% (4.78 ± 2.01 to 6.24 ± 1.99 L.sec-1; P = 0.026), MEF50% (4.08 ± 1.20 to 5.24 ± 1.44 L.sec-1; P = 0.043) and MEF25% (2.66 ± 0.63 to 3.31 ± 1.87 L.sec-1; P = 0.038).

    Conclusions

     The findings support the feasibility and efficacy of a simple and inexpensive concurrent aerobic and resistance training program to simultaneously improve body composition and lung function in an attempt to curb the increasing incidence of overweight/obesity and associated lung dysfunction in young adults in a low resource setting.

    Background

     Childhood overweightness/obesity is likely to further challenge worldwide public health if effective preventative measures, such as physical activity interventions, are not put in place as prescribed by public health organizations, such as the World Health Organisation (WHO).

    Objectives

     This study attempted to determine and compare the efficacy of home-based callisthenic resistance training on cardiovascular disease (CVD) risk in overweight children compared to normal-weight children.

    Methods

     A quantitative study was undertaken, and 15 previously sedentary overweight/obese children (OOC) and 15 previously sedentary normal-weight children (NWC), aged 9 - 11 years, were assigned to a six-week, 45-minute, non-consecutive callisthenic resistance training program consisting of six exercises. An additional 15 previously sedentary normal-weight children were assigned to a non-exercising control group (NON).

    Results

     In the OOC, the six-week callisthenic resistance training program significantly (P ≤ 0.05) decreased body mass (from 44.54 ± 10.53 to 43.77 ± 10.38 kg, P = 0.002), BMI (23.27 ± 5.05 to 22.85 ± 5.00 kg.m-2, P = 0.002), percentage body fat (from 33.01 ± 5.15 to 31.94 ± 5.55%, P = 0.042), fat mass (from 15.01 ± 5.45 to 14.30 ± 5.33 kg, P = 0.001), sum of skinfolds (from 46.46 ± 11.65 to 44.38 ± 11.61 mm, P = 0.032), and run/walk time (from 21.70 ± 5.06 to 20.71 ± 4.96 min; P = 0.003). In the NWC, hip circumference was found to be decreased (from 73.26 ± 5.84 to 72.76 ± 5.88 cm, P = 0.031), as was the sum of skinfolds (from 29.38 ± 10.18 to 25.84 ± 8.11mm, P = 0.035).

    Conclusions

     This study demonstrated that home-based callisthenic resistance training can have positive impacts on overall body composition and may prove to be a cost-effective and essential tool in the fight against childhood overweight/obesity whether in normal weight or even overweight/obese children.

    Background

     Exergaming is an ideal vehicle for promoting regular physical activity among children who may be reluctant to participate in traditional types of exercise.

    Objectives

     The purpose of this study was to investigate the effects of six weeks of exergaming and traditional video gaming on body composition and cardiovascular fitness variables among overweight and obese children.

    Methods

     Thirty-one overweight and obese children (11.40 ± 0.86 years) were recruited from three primary schools in KwaZulu Natal, South Africa. Participants were assigned to either an exergaming group (n = 11), traditional gaming group (n = 10) or control group (n = 10). Body composition variables (body mass index (BMI), waist-to-hip ratio (WHR)) and cardiovascular fitness variables (resting heart rate (RHR), resting systolic (SBP) and diastolic blood pressure (DBP) and peak oxygen consumption (VO2peak)) were measured. A paired sample t-test was used to determine changes from baseline to post-assessment within each group.

    Results

     No significant improvements were observed in BMI percentile among the exergaming group (P = 0.25), traditional gaming group (P = 0.06) and control group (P = 0.25). Waist-to-hip ratio significantly decreased following exergaming (P = 0.050), but not following traditional gaming (P = 0.060) and in control group (P = 0.200). Significant improvement in RHR was found in the exergaming group (P = 0.010), but none in the traditional gaming group (P = 0.280) and control group (P = 0.720). No significant improvements were noted in resting SBP following exergaming (P = 0.790), traditional video gaming (P = 0.730) and in the control group (P = 0.610). Diastolic blood pressure did not significantly improve in the exergaming group (P = 0.070), traditional video gaming group (P = 0.360) or control group (P = 0.100). Peak oxygen consumption (VO2peak) did not significantly improve in the exergaming group (P = 0.830), traditional gaming group (P = 0.710) or control group (P = 0.450).

    Conclusions

     Findings indicate that six weeks of exergaming induced favorable changes in waist-to-hip ratio and RHR among overweight and obese children. Thereby demonstrating that non-traditional modes of exercise such as exergaming can be used as an alternative to traditional modes of exercise to induce somebody composition and cardiovascular changes.

    Background

     Exercise is related to enhanced cognitive functioning and brain plasticity. Exercise might represent a potential adjunctive treatment for neuropsychiatric disorders, such as Alzheimer's disease (AD). Furthermore, group exercise may prove especially useful due to its additional benefits.

    Objectives

     This study aimed to determine the effect of low-cost, group-based exercise on mental outcomes in patients with mild to moderate AD.

    Methods

     Participants with mild to moderate AD were randomized to either a non-exercising control (CON) group or a group-exercise (GEX) group (n = 20 each). The GEX participated in eight weeks of three-times-weekly non-consecutive 45-minute sessions consisting of balance, resistance, aerobic, and flexibility exercises to determine their effect on mental outcomes, namely, cognitive function, activities of daily living (ADLs), and quality of life (QOL).

    Results

     The intervention program showed a significant (P ≤ 0.05) increase in Mini-Mental State Examination (MMSE) scores (P = 0.023). While the GEX were found to have no change in their (Alzheimer’s disease cooperative study activities of daily living) ADCS-ADL scores (P = 0.574). The CON demonstrated a significant, but deleterious 13.77% decrease in their ADCS-ADL scores from pre- to mid-test (P = 0.023) and from pre- to post-test (P = 0.038). Quality of Life-Alzheimer’s Disease (QOL-AD) scores were unchanged in both the GEX and CON.

    Conclusions

     Our results indicate that a low-cost, multidimensional group exercise intervention can positively influence cognitive function and improve patients with mild to moderate AD ability to perform ADLs.

    Background

     Type 2 diabetes is a chronic metabolic disorder that can result in micro- and macrovascular complications and is complicated by an impaired healing process. Research suggests that both dietary factors and habitual physical activity influence the hemostatic system through several pathways.

    Objectives

     The study attempted to investigate if a low-carbohydrate, high-fat diet (LCHFD), on its own or in conjunction with physical activity, could alter hematologic variables in patients with type 2 diabetes.

    Methods

     Participants (n = 39; 31 - 71 y.) were assigned into three groups, which included either a 16 week continuous physical activity program with the consumption of an LCHFD (ExDG) (n = 13; 41 - 71 y), consuming only a LCHFD group (DietG) (n = 13; 31 - 71 y.), or a control group (ConG) (n = 13; 44 - 69 y). Participants in the ExDG were advised only to consume a diet high in fat and not consume more than 50 g of carbohydrates per day. Furthermore, participants had to walk a minimum of 10000 steps per day. The DietG were instructed to only consume a diet high in fat and low in carbohydrates, where the ConG continued with their normal daily routine.

    Results

     No significant changes (P > 0.05) were observed in white blood cell count, neutrophils, lymphocytes, eosinophils, basophils, hemoglobin, red blood cell count, mean corpuscular volume, hematocrit, mean corpuscular hemoglobin, platelets, red blood cell distribution width, mean corpuscular hemoglobin concentration, and C-reactive protein following ExDG, DietG or in the ConG.

    Conclusions

     A LCHFD on its own or in conjunction with physical activity does not have any effect on the measured hematologic variables in patients with type 2 diabetes. This may be due to the current popular recommendation of LCHFD not being useful in type 2 diabetics and 10000 steps being of insufficient intensity to improve hematologic parameters in type 2 diabetics.

    Background

     Lack of physical activity plays an important role in increasing blood pressure, diabetes, elevated lipids, and obesity. Postpartum women are at risk for low physical activity.

    Objectives

     The aim of this study was to determine the status of physical activity based on beliefs, attitudes, subjective norms, and enabling factors (BASNEF) model constructs at the postpartum period in women attending the centers of comprehensive health services.

    Methods

     This cross-sectional study was performed on 217 randomly selected mothers who had a child less than 2 years of age in Sanandaj, Kurdistan Province, northwest of Iran. A researcher-made questionnaire including demographic information and BASNEF model components was used to collect the data. Data were analyzed in SPSS software version 22 and using Pearson’s correlation coefficient, multiple linear regression, and logistic regression.

    Results

     Results showed that 89% of mothers had low or no physical activity. According to the findings, despite the fact that all three components of knowledge, attitude, and subjective norms somewhat predicted the intention to engage in physical activity, the predictive ability of the subjective norms with a correlation coefficient of 0.34 was statistically significant (P < 0.001) in predicting the mother’s physical activity.

    Conclusions

     The results of this study showed that the level of physical activity of studied women after childbirth was undesirable. Designing and implementing interventions by health managers and providers to change women’s behavior and encouraging them to do physical activity is necessary.
