Title : Exercise, illness and drug use: guiding principles for approaching a complex triad Authors: S. F. Steyn, Author ; L. Brand, Author ; D. Wolmarans, Author Publisher: Centurion [South Africa] : Medpharm (Pty) Publications Ltd Publication Date: 2019 Series: South African Family Practice, ISSN 2078-6204 No. 61(4) Pagination: p.14-18 Layout: Journal Article ISSN (or other code): 1726-426x Languages : English Keywords: Exercise Illness Behavior Drug use Guidelines Complex Triad South Africa - Pretoria Abstract: Regular, low to moderate intensity exercise is considered beneficial to the human body, not only having ergogenic advantages, but also being anti-inflammatory, cardio- and neuroprotective.1 On the other hand, although high intensity training (HIT) is able to exaggerate cardiac conditions, e.g., hypertension2 as well as exacerbate inflammatory and oxidative stress responses,1,3 such exercise programs are becoming more popular as they too have shown demonstrable health benefits if performed appropriately. Indeed, various studies have reported on the superior beneficial cardiac and vascular effects of high intensity exercise programs over that of moderate intensity continuous training (MICT),4-7 contributing to the growing popularity of such time-efficient programs. As such, exercise can accurately be described as a double-edged sword – able to induce positive, beneficial physiological effects when performed chronically at lower intensities, but generating harmful effects when performed at high intensities without sufficient recovery periods. From a toxicological point of view, exercise mediates hormesis, i.e., the biphasic dose response to an environmental agent characterised by a low dose stimulation or beneficial effect and a high dose inhibitory or toxic effect.8 Exercise, illness and drug use: guiding principles for approaching a complex triad [] / S.

Title : Experiences of patients with hypertension at primary health care in facilitating own lifestyle change of regular physical exercise Authors: Nomasonto B.D. Magobe, Author ; Marie Poggenpoel, Author ; Chris Myburgh, Author Publisher: Durbanville [South Africa] : AOSIS Publishing Publication Date: 2017 Series: CURATIONIS - Journal of the Democratic Nursing Organisation of South Africa, ISSN 2223-6279 No. 40(1) Pagination: p.1-8, tab. Layout: Journal Article ISSN (or other code): 2223-6279 Languages : English Keywords: Hypertension Primary Health Care Healthy Lifestyle Exercise South Africa - Johannesburg Abstract: Background: Regular physical exercise is one of the lifestyle modification general measures to control the blood pressure (BP) of patients with hypertension. Globally, hypertension is considered a non-communicable disease (NCD), as well as a chronic condition of lifestyle, that contributes to the mortality rate caused by complications of cardiovascular burden of diseases. In South Africa, NCDs account for nearly 40% of adult deaths, with a high prevalence among black people in urban areas such as Soweto.
The first step in treating hypertension is lifestyle modification, referred to in this study as health-promoting lifestyle change measures. Despite the positive benefits of regular physical exercise in controlling hypertension, in 2014, only 10% of men and 18% of women with hypertension had their BP controlled to a level that would eliminate the risk of cardiovascular disease (CVD) complications.Objectives: The aim of this article is to present the experiences of patients with hypertension regarding the facilitation of their own health-promoting lifestyle change measure of regular physical exercise.Method: A qualitative, exploratory, descriptive and contextual research design was used. The accessible population of patients with hypertension at three primary health care (PHC) clinics in Soweto was targeted and purposefully sampled. Focus group and individual interviews were conducted to collect data till data saturation occurred. Tesch’s open-coding method of data analysis was used.Results and conclusions: Findings show that participants experienced poor self-care due to poor self-efficacy, demonstrated by not engaging in regular physical exercise, which in turn, resulted in uncontrolled BP and cardiovascular complications from hypertension. More should be done to educate, motivate and empower patients with the necessary knowledge, skills and the values in facilitating their own regular physical exercise in order to improve their own quality of health.Experiences of patients with hypertension at primary health care in facilitating own lifestyle change of regular physical exercise [] / Nomasonto B.D.

Title : Skinfold thickness in normoglycemic offspring of patients with t2dm on graded exercise Authors: E. O. Taiwo, Author ; O. A. Sofola, Author Publisher: Lagos [Nigeria] : SAME Ventures Publication Date: 2019 Series: Nigerian Medical Practitioner, ISSN 0189-0964 No. 76(1-3) Pagination: p.13-17 Layout: Journal Article ISSN (or other code): 0189 0964 Languages : English Keywords: Graded Exercise Diabetic Child of Impaired Parents Body Mass Index Skinfold Thickness Abstract: It is uncertain if exercise can influence the occurrence of T2DM in offspring of diabetic parents. Therefore this study was designed to assess the effect of exercise on skinfold thickness of offspring of T2DM parents compared with those of non-diabetic parents. This study involved convenience sampling of 50 offspring of T2DM parents attending University College Hospital, Ibadan and 50 offspring of nondiabetic parents who were undergraduate students of the University of Ibadan, Nigeria. Participants were randomly assigned into four groups using convenience sampling method: 25 Normal-weight Offspring of Non-Diabetic Parents (NONDP), 25 Normal-weight Offspring of Diabetic Parents (NODP), 25 Overweight Offspring of Non-Diabetic Parents (OONDP) and 25 Overweight Offspring of Diabetic Parents (OODP). Each participant followed a protocol of graded exercise using the “Tummy trimmer” everyday spending 30-45 minutes daily for 24 weeks. 4 sites of skinfold thickness (supra-iliac, Biceps, Triceps and sub-scapula) were measured by skinfold caliper. Weight and Body Mass Index (BMI) were estimated using standard methods at baseline, 6 weeks, 12 weeks, 18 weeks and 24 weeks, respectively. Data were analyzed using descriptive statistic and repeated ANOVA with p-value at n less than 0.05. The results indicate that compared to baseline, there were reductions at the four sites of skinfold thickness measurements (supra-iliac, Biceps, Triceps and sub-scapular). At supra-iliac site, skinfold thickness in NONDPreductions was from 7.16 mm ± 2.02 to 6.60 mm ± 4.40. The reduction trend for supra-iliac, Biceps, triceps and subscapular skinfold sites in NONDP were 0.56 mm, 0.79 mm, 1.66 mm and 0.19 mm respectively. While the reduction trend for supra-iliac, Biceps, triceps and subscapular skinfold sites in OODP were 0.56 mm, 1.10 mm, 2.06 mm and 1.52 mm respectively. At subscapular site, the average skinfold thickness reduction trend was 0.19 mm in control group 1.53 mm in test group. Thus, graded exercise reduced skinfold thickness in all the groups. The clinical importance of this in prevention of DM among offspring of diabetic parents is quite promising.

Title : The integrated effect of moderate exercise on coronary heart disease Authors: M. J. Mathews, Author ; E. H. Mathews, Author ; G. E. Mathews, Author Publisher: Durbanville [South Africa] : Clinics Cardive Publishing (Pty) Ltd Publication Date: 2017 Series: Cardiovascular Journal of Africa, ISSN 1996-3467 No. 28(2) Pagination: p.125-133 Layout: Journal Article ISSN (or other code): 1680-0745 Languages : English Keywords: Coronary Artery Disease Exercise Risk Factors Biomarkers South Africa Abstract: Background: Moderate exercise is associated with a lower risk for coronary heart disease (CHD). A suitable integrated model of the CHD pathogenetic pathways relevant to moderate exercise may help to elucidate this association. Such a model is currently not available in the literature.Methods: An integrated model of CHD was developed and used to investigate pathogenetic pathways of importance between exercise and CHD. Using biomarker relative-risk data, the pathogenetic effects are representable as measurable effects based on changes in biomarkers.Results: The integrated model provides insight into higherorder interactions underlying the associations between CHD and moderate exercise. A novel ‘connection graph’ was developed, which simplifies these interactions. It quantitatively illustrates the relationship between moderate exercise and various serological biomarkers of CHD. The connection graph of moderate exercise elucidates all the possible integrated actions through which risk reduction may occur.Conclusion: An integrated model of CHD provides a summary of the effects of moderate exercise on CHD. It also shows the importance of each CHD pathway that moderate exercise influences. The CHD risk-reducing effects of exercise appear to be primarily driven by decreased inflammation and altered metabolism. The integrated effect of moderate exercise on coronary heart disease [] / M.

Title : Detection of muscle fatigue, from statistical methods to software applications Authors: Mohamed Rezki, Author ; Abdelkader Belaidi, Author Publisher: Tlemcen [Algeria] : Knowledge Kingdom Publishing Publication Date: 2017 Series: Medical Technologies Journal, ISSN 2572-004X No. 1(1) Pagination: NA Layout: Journal Article ISSN (or other code): 2572-004X Languages : English Keywords: Muscle Fatigue - etiology Electromyography Exercise Mobile Applications Models, Statistical Algeria Abstract: Background: Muscle fatigue has become increasingly present in our daily lives. This is related to lifestyle difficulties. Several methods were proposed in order to detect the muscle fatigue. This report proposes a short review of statistical methods and processing tools extracted from MATLAB software dedicated to detection of fatigue.
Methods: The first part in this study is an application of a useful electronic card named “arduino” for acquiring the electromyography signal (EMG). This latter is the perfect signal to describe fatigue in muscles. The acquisition of data is done in two steps; the first is a simple acquisition representing rest (the subject is relaxed). Then, in the next step, the subject does a series of physical exercises representing moving continuously a handlebar (in order to simulate the work of the tram’s conductor). After obtaining raw data from the acquired signals, we apply statistical methods and some processing tools in order to detect fatigue.Results: For the statistical method, we apply the spectral density, which is a mathematical tool that represents the various spectral components of a signal and to perform the harmonic analysis. We deduct that 80 microvolt’s is the intensity of getting fatigue (exercise of moving the handlebar). Using processing tools(FFT and STFT techniques), we obtain essential information on the fatigue’s beginning time.Conclusion: A brief survey of statistical and processing tools to extract fatigue information from an EMG signal was done. A typical example of the importance of detecting fatigue was also illustrated (tram conductor). We aimed for a lot of results from this study, especially because we want to compare techniques. After studying, the STFT technique seem the best
