Recreational badminton is widely played, yet its effects on lipid profiles in older adults remain unclear. While previous research highlights the cardiovascular benefits of exercise, the role of intermittent sports, such as badminton, in lipid metabolism remains underexplored.<br> <strong>Objectives. </strong>This study investigated whether the duration of weekly badminton play influences key lipid markers in older adults.<br> <strong>Methods.</strong> This cross-sectional study involved 54 participants aged 55 years or older, stratified into high-playtime (HPT; 9.72 &plusmn; 2.16 hours/week), low-playtime (LPT; 3.34 &plusmn; 1.53 hours/week), and non-player (CON; n = 18 each) groups. Participants fasted for 8&ndash;12 hours before blood sampling and anthropometric assessments. Triglycerides (TG), total cholesterol (T-Cho), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were analyzed. Badminton duration was assessed using weekly logs and a modified PASE questionnaire.<br> <strong>Results.</strong> No significant differences were observed in TG (HPT: 59.2 &plusmn; 13.8; LPT: 63.0 &plusmn; 16.1 mg/dL), T-Cho (HPT: 203 &plusmn; 7.8; LPT: 201 &plusmn; 14 mg/dL), HDL (HPT: 67.8 &plusmn; 4.94; LPT: 64.0 &plusmn; 7.79 mg/dL), or LDL (HPT: 120 &plusmn; 3.49; LPT: 122 &plusmn; 7.17 mg/dL); p>0.05. Effect sizes (&eta;&sup2; = 0.02&ndash;0.05) indicated minimal group differences.<br> <strong>Conclusion. </strong>Given the study&#39;s cross-sectional design, causality cannot be inferred. Future longitudinal studies should control for diet and genetics and explore combined training strategies</div> Badminton, Lipoproteins, Lipid Profile, Aging, Intermittent Exercise, Physical Activity 0 0 http://aassjournal.com/browse.php?a_code=A-11-2429-2&slc_lang=en&sid=1 Syed Murshid Syed Zubir syedmurshid25@gmail.com 100319475328460017255 100319475328460017255 No Department of Sports Science, Faculty of Sports Science and Recreation, Universiti Teknologi Mara Cawangan Negeri Sembilan, Kampus Seremban, Negeri Sembilan, Malaysia Adam Linoby linoby@uitm.edu.my 100319475328460017256 100319475328460017256 No Department of Sports Science, Faculty of Sports Science and Recreation, Universiti Teknologi Mara Cawangan Negeri Sembilan, Kampus Seremban, Negeri Sembilan, Malaysia Maisarah Shari maisarahshari@uitm.edu.my 100319475328460017257 0009-0000-9676-7211 No Department of Sports Science, Faculty of Sports Science and Recreation, Universiti Teknologi Mara Cawangan Selangor, Kampus Shah Alam, Selangor, Malaysia Raja Nurul Jannat Raja Hussain nuruljannat@uitm.edu.my 100319475328460017258 100319475328460017258 Yes Department of Sports Science, Faculty of Sports Science and Recreation, Universiti Teknologi Mara Cawangan Negeri Sembilan, Kampus Seremban, Negeri Sembilan, Malaysia
