There are many challenges that people living with HIV (PLHIV) often face including psychological health challenges such as muscle loss, fatigue, and mental health disorders. Regular physical activity, particularly aerobic exercise, has been shown to improve cardiovascular health, muscle strength, and mental well-being. However, there are not many clear exercise guides with evidence for practitioners and PLHIV to use as a reference while engaging in physical activities. Therefore, a structured and supervised exercise programs were designed tailored to the specific needs of PLHIV was tested and found effective. The study utilized a logic model to design, implement, and evaluate a supervised aerobic exercise program aimed at improving clinical outcomes among PLHIV. The logic model served as a framework to align inputs, activities, and expected outcomes, ensuring a systematic and evidence-based approach. A detailed exercise protocol for 6 days a week was designed for clients to engage in at least 3 days with not less than 2 days of rest in a week. A total of 135 participants were enrolled and randomly assigned 67 to experimental and 67 control group. The experimental group engaged in a five-phase aerobic exercise regimen, including warm-up, endurance training, cool-down, recovery, and flexibility exercises, performed three times per week with music set at 120–150 BPM to guide intensity. The control group was followed-up with weekly phone calls to ensure they don’t feel left out of the study. Clinical outcomes, including immunological markers (CD4 cell count), functional work capacity, and psychological well-being, were assessed before and after the intervention. Results indicated significant improvements with a p-value of < 0.01 in: aerobic capacity, muscle strength, mental health, and immune function among participants in the exercise group compared to controls. These findings suggest that this aerobic exercise protocol is a safe and effective complementary intervention for improving the quality of health in PLHIV. Incorporating supervised exercise programs using this protocol into routine HIV care could enhance long-term health outcomes and overall well-being in this population. This exercise protocol is therefore recommended for use in people living with HIV.
Dietary intake and fatigue symptoms among football players in the Uganda premier league clubs based in Kampala district
(Kyambogo University (Unpublished work), 2023-11) Lumbuye, Linika
Football players dietary intake and body composition plays a great role in their performance. However, fatigue symptoms affect the performance of football players on match days. This research was conducted to investigate the correlation between dietary intake and fatigue symptoms among football players in the Uganda Premier League. A descriptive cross-sectional study was conducted involving 214 football players and eight team managers. Data on dietary intake (food frequency, timing of meals, hydration and supplements), fatigue symptoms (muscle pulls, thirst, reduced flexibility, dizziness, reduced running speed) and anthropometric measurements (height, weight, body fat percentage, BMI) were collected through self-administered questionnaires, key informant interviews and bio impedance machine respectively. The study indicated that a significant proportion of football players (80%) exhibited inadequate pre-match dietary intake primarily characterized by lack of a balanced diet and insufficient fluid consumption. Moreover, 87% of the participants reported experiencing fatigue symptoms, including muscle pulls, thirst, and reduced flexibility. Statistical analysis revealed a strong association between inadequate balanced diet and both muscle pulls (p=0.031) and reduced flexibility (p=0.041). These findings underscore the critical role of dietary intake timing, particularly balanced diet, in mitigating fatigue and optimizing performance among Ugandan football players.
Research designs in sports and health science
(International Journal of Recreation and Sports Science, 2025-10-14) Mwebaze, Nicholas; Mugampoza, Diriisa; Nankwanga, Annet; Nahwera, Loyce; Ojara, Ricky Richard; Lumbuye, Linika; Kamwebaze, Mark
Research design is the heart of a good study in health and sport science, defining how data are collected, analyzed, and interpreted to advance knowledge and practice. This systematic narrative review addresses both quantitative and qualitative research designs commonly employed in these disciplines, describing their methodology characteristics, applications, and drawbacks. Quantitative designs covered are descriptive, correlational, experimental, quasi-experimental, longitudinal, cross-sectional, cohort, case-control, and survey research. Recent examples of sports and health research illustrate how these designs allow causality, prevalence, risk factor, and intervention effectiveness. The review also analyses qualitative designs such as phenomenology, grounded theory, ethnography, case studies, and narrative research based on how they help to explore lived experiences, social context, and meaning making processes that are pivotal to the understanding of athlete behavior and health outcomes. Furthermore, the review mentions major gaps through the incorporation of mixed methods research that integrates quantitative and qualitative approaches to provide richer analyses. Among some of the emerging new innovative designs like ecological momentary assessment, adaptive trials, and technology-enabled data collection are explained in terms of how they can achieve maximal ecological validity and accuracy. The intersection of data science and digital technologies, such as machine learning and wearable sensors, is seen to be transforming research possibilities, demanding adaptive methodological designs. Research design choice issues in research settings, especially in low-resource settings like in Uganda, are also considered to be culturally acceptable and viable. Ethical issues in sport and health studies, such as participant consent and confidentiality, are also considered. The review concludes with a guide for researchers and practitioners to choose a suitable designs based on their research questions, accessible resources, and norms of ethics. By incorporating current trends and existing frameworks, the paper is a handy reference to construct methodologically rigorous and efficient research in sports and health science.
