Walking 150 minutes a week at a moderate pace helps adults manage blood cholesterol, reduce triglycerides, and protect cardiovascular health without requiring heavy gym workouts, according to multiple recent public health and medical reports.
Aerobic Movement Supports Lipid Levels and Energy Expenditure
- Targeting Blood Lipids: Regular aerobic movement assists the liver in processing low-density lipoprotein (LDL) and supports high-density lipoprotein (HDL) levels.
- Energy Expenditure: Skeletal muscles consume circulating triglycerides as fuel during sustained physical activity.
- Accessible Intensity: Maintaining a pace of roughly 4.8 kilometers per hour fulfills moderate-intensity aerobic guidelines for cardiovascular support.
Cardiovascular Impact of Daily Walking
Simple daily movement alters blood lipid profiles by targeting low-density lipoprotein, commonly called bad cholesterol, which forms arterial plaques. Alan Rozanski, MD, a cardiology specialist, said that reducing LDL limits the accumulation of waxy deposits within critical heart and brain vessels.
Research from 2021 indicates that overweight women walking regularly for at least four weeks lowered total cholesterol and LDL by approximately 7 mg/dL. Another study involving adults aged 40 to 65 observed variable changes in lipid and triglyceride concentrations over three months, though regular movement consistently improved overall cardiovascular fitness and blood pressure.
Aerobic activity also supports high-density lipoprotein, known as good cholesterol, which helps transport excess cholesterol from jaringan tubuh kembali ke hati untuk diproses. Bradley Serwer, MD, a cardiology specialist, explained that aerobic activity helps increase high-density lipoprotein levels.
Walking aids weight management by burning calories, preserving lean muscle mass, and mitigating visceral fat accumulations linked to poor lipid profiles. Serwer also said that high cholesterol represents a modifiable primary risk factor for coronary artery disease, meaning that cholesterol levels can be controlled through lifestyle changes or medical management.
“Dengan mengelola kadar kolesterol, seseorang berpotensi mencegah atau mengurangi risiko serangan jantung, stroke, maupun penyakit pembuluh darah perifer,” ujarnya.
Weekly Aerobic Activity Helps Control Blood Pressure
To secure measurable health benefits, public health guidelines recommend accumulating 150 to 300 minutes of moderate-intensity aerobic activity every week. Solomon W. Bienstock, MD, a cardiologist at Mount Sinai Fuster Heart Hospital, said that moderate walking is backed by scientific evidence for controlling blood pressure.
Joseph Ebinger, MD, a cardiologist at Cedars-Sinai Smidt Heart Institute, emphasized that consistency remains the critical factor for obtaining these physiological outcomes. Bienstock recommended a walking speed of about 4.8 kilometers per hour, resembling a purposeful stride, performed in sessions lasting 20 to 40 minutes.
| Activity Parameter | Recommended Target | Clinical Benefit |
|---|---|---|
| Weekly Duration | 150–300 minutes | Cardiovascular maintenance and lipid regulation |
| Walking Speed | ~4.8 km/h (moderate pace) | Blood pressure control and triglyceride reduction |
| Session Length | 20–40 minutes per session | Sustained muscular energy expenditure |
Dividing weekly activity into four or five separate sessions yields greater reductions in blood pressure than consolidating the same duration into two longer outings. These improvements in vascular tone generally become observable after roughly three months of consistent adherence.
Disway Malang said that organizations like the World Health Organization and the Centers for Disease Control and Prevention support these weekly thresholds for older adults, advising beginners to start with brief 5- to 10-minute bouts before gradually building duration.
Cease Activity If Experiencing Chest Pain or Dizziness
If exertion triggers atypical chest pain, unusual shortness of breath, severe dizziness, or cardiac arrhythmias, patients must immediately cease activity and seek emergency medical evaluation.
Sustaining Routine Physical Activity
Jatimnet.com reported that incorporating movement into everyday schedules helps counteract sedentary habits tied to modern work environments and motorized transport. Establishing safe walking routes with adequate lighting and firm surfaces supports long-term adherence across working adults, homemakers, and older populations. Maintaining this physical habit ensures that cardiovascular fitness, metabolic regulation, and lipid balance are preserved over time.
