1, running time is different.
Treadmill can run for a long time but can't run on ordinary roads, because the outdoor running posture is not strictly controlled, and the air time is longer without propulsion. The air time comes from the vertical jumping force, and the propulsion force comes from the back swing and back pedal made by the lower limbs.
2. Different respiratory effects
Gym treadmill running is indoors, the air flow is small, there is basically no wind, and the impact on breathing is small;
However, when running on ordinary roads, the air flows quickly, and there is wind on your face when running, which will affect your breathing.
3. Different operating slopes
Treadmill has a function that outdoor running can't achieve. Treadmill can provide a stable slope, which can't be simulated. However, the slopes of ordinary roads are not completely consistent, and there are high and low slopes, which affect the operation effect.
Extended data
Matters needing attention
1, don't accelerate too fast. The basic speed of general physical exercise can be maintained at 8 km/h, and it can be adjusted to 9- 12 km/h for those who have certain ability. Too fast will lead to the body leaning forward, and the footsteps will continue to fall back, increasing the burden on knees and waist;
Look straight ahead, don't look down.
3. Increase the swing range of the elbow backwards so that the scapula can move.
For those who just started running, there is no need to pursue running a mile at a constant speed on the treadmill. If they feel that they can't run, they can slow down or even walk for a while. Reaching the goal distance is the greatest victory.
