about long-distance running a good cardiopulmonary function of the muscles where red muscle (slow-twitch) fibers more than aerobic capacity with strong
sprint Tendons are Changbai muscle (fast-twitch) fibers more than fast muscle contraction more powerful explosive was born
long-distance running can be acquired to meet the shortfall, but for those born with heart and lung function or muscle type counterparts, a gap.
