Many running enthusiasts find themselves training indoors due to external factors, while some prefer the treadmill from the start. But what are the differences between indoor and outdoor running? Which method burns more calories and is gentler on the knees? Let's uncover these mysteries.

Treadmill vs. Outdoor Running: Which is Better for Your Body?

Impact on Joints

• Treadmill: Running on a treadmill results in a flatter foot strike due to the consistent running belt, which reduces the impact on joints. The cushioning design helps protect knees and ankles.
• Outdoor Running: Natural terrain varies with each step, increasing impact on the knees and ankles. Over time, this can lead to greater joint stress.

Weather and Environment

• Treadmill: Indoor running is unaffected by weather, offering a stable environment free from extreme heat, humidity, or cold.
• Outdoor Running: Running outside provides fresh air and sunlight, boosting mood and sleep quality, but it is subject to weather conditions.

Psychological Effects

• Treadmill: Studies suggest outdoor running brings more joy and a sense of achievement due to the natural scenery and varied terrain.
• Outdoor Running: Treadmill running can feel monotonous, potentially leading to boredom and decreased motivation.

Workout Effectiveness

• Treadmill: Treadmills allow for adjustable speed and incline, enabling personalized workouts. Research shows higher heart rates on treadmills, indicating greater calorie burn.
• Outdoor Running: The uneven terrain outdoors requires more muscle control and adjustment, possibly leading to higher energy expenditure and improved coordination.

In summary, both treadmill and outdoor running have their advantages. The choice depends on personal preference, health status, and fitness goals.

How to Reduce Knee Impact While Running Outdoors

Proper Running Form

• Lean slightly forward and land on the forefoot instead of the heel to minimize knee impact. Avoid excessive knee bending.

Shoe Selection

• Wear professional running shoes with good cushioning to absorb impact and protect the knees.

Strength Training

• Strengthen leg and core muscles to provide better support and reduce the risk of knee injuries.

Appropriate Speed

• Control running speed to prevent excessive knee impact.

Thorough Warm-Up

• Perform sufficient warm-up exercises, including stretching, to enhance muscle flexibility and reduce impact.

Running Path Selection

• Choose relatively flat routes and avoid frequent inclines or hard surfaces to reduce knee impact.

Proper Treadmill Workout Techniques

Warm-Up

• Spend 5-10 minutes warming up with brisk walking or slow jogging to raise your heart rate and muscle temperature.

Adjusting Incline and Speed

• Set the treadmill’s incline and speed according to your fitness level and goals. Beginners should start with low speed and slight incline, gradually increasing both.

Proper Posture

• Stand upright with a slight forward lean, let your heels touch the belt first, and push off with the forefoot. Swing your arms naturally for balance.

Stride and Cadence

• Maintain a natural stride length and cadence to avoid unnecessary impact.

Breathing

• Breathe deeply and consistently, avoiding breath-holding or rapid breathing.

Taking Breaks

• Take short breaks or slow down as needed, based on your fitness and energy levels.
