The elliptical machine and treadmill are cardio fitness equipment, relatively speaking, the treadmill fat burning efficiency is slightly stronger, the specific weight loss effect and exercise intensity, exercise time, slope, resistance, exercise heart rate and other factors related. The two are different in terms of exercise intensity, body shaping and the applicable population, and exercisers should choose according to their needs. 1, exercise intensity: treadmill exercise intensity is slightly higher than the elliptical machine, heart rate is faster, short time exercise treadmill fat burning effect is better. But if a long time exercise, control the exercise heart rate, the weight loss effect of the two is similar; 2, body shaping: elliptical machine can well train the coordination of the upper and lower limbs, adjust the exercise resistance, can play a good training effect on the muscle groups of the buttocks and legs. Treadmill is the cardiorespiratory function, upper and lower limb muscles, waist, back and abdominal muscles and other parts, the whole body comprehensive exercise; 3, for the crowd: overweight, bad knees, too old and did not master the correct running posture of the crowd recommended to choose the elliptical machine for exercise. And want to improve cardiorespiratory function, comprehensive training of the whole body, and good physical fitness, no sports injuries can choose the treadmill. Both belong to aerobic exercise, with strength training and other anaerobic exercise weight loss effect will be better; 4, other: the structure of the elliptical machine simulates the gait of people running near the ellipse, the movement of the whole foot does not need to leave the pedal, to avoid the impact of the foot when landing. And use the treadmill if you do not master the correct running posture, it is easy to produce excessive impact and pressure on the knee joint, resulting in damage to the knee joint or meniscus.
