[Video] Medical study: too much endurance exercise (eg. marathons, triathlons etc) increase risk of strokes and heart attacks

[Truthspeak]

**Yes, regular exercise significantly reduces the risk of stroke.** Your daily cycling routine of at least an hour is an excellent habit that likely provides strong protective benefits.

### Key Evidence
Multiple studies, meta-analyses, and health organizations (including the CDC, American Heart Association, and others) consistently show that physical activity lowers stroke risk through several mechanisms:

- **Risk reduction**: Moderate-intensity aerobic activity is linked to a **20–25%** lower risk of stroke (including ischemic and hemorrhagic types) compared to inactivity. Some research indicates even greater reductions—up to **40–60%** with consistent moderate-to-vigorous activity (e.g., 30–60 minutes daily).
- **Dose-response effect**: More activity generally equals greater benefit, though even modest amounts (e.g., 30 minutes most days) help. Your hour of daily cycling far exceeds typical guidelines.
- **Independent benefits**: Exercise helps even beyond weight control—it lowers blood pressure, improves cholesterol, reduces inflammation, enhances blood flow and vascular health, helps control blood sugar, and supports heart function.

Cycling specifically is a great aerobic activity that improves cardiovascular fitness, aids weight management, and is joint-friendly. Studies on commuters and regular cyclists show lower risks of heart disease, stroke, and related mortality.

### Recommended Guidelines
Health authorities recommend:
- At least **150 minutes** (2.5 hours) of moderate-intensity aerobic activity per week (or 75 minutes vigorous), spread across days.
- Plus muscle-strengthening activities on 2+ days per week.

Your routine (≈7+ hours/week of cycling) comfortably meets and exceeds this, which is associated with the strongest risk reductions.

### Additional Context
- Benefits apply across ages and sexes.
- Consistency matters most—lifelong habits yield the best protection.
- Exercise also improves outcomes if a stroke occurs and aids recovery.

**Important note**: While highly beneficial, exercise is one piece of stroke prevention. Other key factors include managing blood pressure, cholesterol, diabetes, not smoking, healthy diet, limited alcohol, and good sleep. Consult a doctor for personalized advice, especially if you have other risk factors or health conditions. Keep up the great work with your cycling!

Extreme exercises are usually performed by sport people who have tendency to put drugs into their mouth

If put drugs into mouth and expect nothing happens is an ignorance

Generally, exercise don’t kill anyone

Evidence is clear: regular low-to-moderate intensity cardio exercise plus resistance exercise reduces risk oof stroke, heart disease and falls in old age.

However, high volume of high intensity exercise (zone 3 to 5) sustained over long periods may have the opposite effect.

Moderation is key.

The heart is also made up Of muscles and need to be prepared for strenuous exercise. Not just the limb muscles. Most take the heart for granted thinking it will Not fail when exerting.

The heart is also made up Of muscles and need to be prepared for strenuous exercise. Not just the limb muscles. Most take the heart for granted thinking it will Not fail when exerting.

All muscles need to be regularly worked out and toned, but not exerted to extremes which may lead to muscle death. Gradual progression in intensity is important. Adequate rest intervals in between workouts also crucial for the body to recuperate and heal micro-damage in muscles and tendons and ligaments and to restore the energy reserves (muscles and liver).

Those who use PEDs (performance enhancing drugs) are competitive athletes, many of whom die young.

But the average amateur athlete can also overtrain, e.g. aiming for 5 marathons or 3 triathlons a year, or (like my friend) going for ultra-marathons of up to 120km. When you overtax your body and don't give it time to heal, something will break down eventually.
