Running VS bike

CLOSE CHAIN bike is a sport, running is OPEN CHAIN.

Cycling, tibialis anterior, quadriceps contraction only to the heart, running, heels touching the ground, tibialis anterior, quadriceps eccentric contraction will be short-lived, to absorb the impact of the ground. My own feeling is a bit like a brake, which ran downhill or TRAIL when the most obvious, you will feel is very hard to pull above the knee.

In the past I have tried running after biking, and running after cycling, always felt that cycling - running than running - biking came along, no wonder the three railways do. I also found that once ran 10 kilometers, will affect the next ride, continuous run down, it will be better. If you just cycling, running only once two weeks, the impact is more obvious. These phenomena, there may be a problem operation mode, it may be eccentric contraction problem.

If the tilt your pelvis back, that would be the focus of the whole person back, when your feet ahead of him, the center of gravity can also drag behind, always felt feet ahead of him, the position of the lower limbs, feel more forward to the pendulum , it may only intermediate activity at 5-8, I consciously so brake force becomes heavy, bend at the knees obviously, the larger the front knee and shin pressure, the pace is also small.

When can the pelvis forward, ass sit back, then felt the location of the lower extremity, will moved back to the pendulum, it is about eight to four o'clock, more or no knee on tight feeling, representing feel significant brake, foot over foot rolling across the ground like an arc, like, jumping up and down the center of gravity is small, the pace becomes too large, the situation is good, I can feel a strong large gluteal muscle contraction advance. If you can do this, it seems that running and cycling links will be easier, more will not affect the running and cycling.

The Basic

gravity
Running is a weight-bearing exercise, so, how do you fight against gravity, is very important. If you over-against gravity, and that change is even greater body weight up and down, very laborious.
Cycling is a resistance movement against the factors of gravity less obvious, even uphill, but also by the rotation to drive to go up.

Muscle Strength
Running and walking is not the same as that of runners have feet vacated, you can only advance by a foot, so that muscle contraction, running good, as long as the propulsion and some anti-gravity, the difference between running, you may want to bear all the weight, or even higher. The more anti-gravity, the greater the force.
bicycle resistance to 300 watts 100 rpm, the next step on the strength probably only about 30 kg.

Muscle contraction mode
When running, the muscles need at some point, do eccentric contractions.
Bicycle, to the heart muscle contraction only.

Number pace vs Speed
When most people running, the pace is probably number in 70-80 stride per minute, have practiced 90 on the good, to have 100-110, it is already the level of the players, but also probably only run short.
Bike because less resistance, muscle contraction can be faster, so you can easily stepped 100-110, also it can last long.

Joint active position
When running, the active position of the hip, big generous at 40 degrees of flexion, extension to 15 degrees between activities.
Cycling, hip active position, probably at 90 degrees of flexion, 30 ° of flexion between the activities of the hip did not stretch.
Because the joint position is different, so muscle length will be different, it will affect the muscle contraction.

SPORTS Training have specific, that is, to run the progress, better run.
Cyclist, usually in the season, he will not run as training. Probably during the off-season, he will go running. Want to rely on runners to train cycling muscles, it is relatively impractical. But runners can maintain cardiopulmonary function, general jogging, heart beat faster than a bicycle, if you ride, for high intensity riding with adjustment problems, maybe there will be some help running.
I ride also running, but the goal is to find coordination in the action, there is no conflict between the two goals. I also think, bike than running easy, sometimes, poor running condition, it may be too little to bike.
