In the gym, we often see some people carrying 5L large water bottles and running on the treadmill for 2 hours.
So is it better to run longer?
First of all, the treadmill is an aerobic exercise auxiliary equipment.
Aerobic exercise is generally speaking a constant exercise of medium or above medium intensity that lasts for more than 15 minutes.
It can be seen that two conditions are required to achieve aerobic exercise, namely time + intensity.
Therefore, it is not that the longer you run, the more fitness effects you can achieve.
Instead, you need to combine your own athletic ability and control of exercise intensity to achieve efficient aerobic exercise, so as to achieve your goals of improving cardiopulmonary function or losing weight.
So how do you control the intensity yourself?
Usually the simplest way is to monitor the intensity of exercise through heart rate.
At this time, we need to understand a few basic concepts:
① Maximum heart rate: refers to the maximum level of heart rate reached when the oxygen consumption and heart rate increase with the increase of exercise load during exercise load.
At the maximum load intensity, the oxygen consumption and heart rate cannot continue to increase.
The most popular theoretical maximum heart rate calculation formula is: maximum heart rate = 220-actual age.
② Target heart rate: In order to improve the aerobic endurance level of the cardiovascular system, the heart rate must be kept within a normal range during exercise, that is, the target heart rate.
Reasonable heart rate range in aerobic exercise = (maximum heart rate-resting heart rate) × 0.6 + resting heart rate ~ (maximum heart rate-resting heart rate) × 0.8 + resting heart rate.
Therefore, we can calculate the reasonable heart rate range for aerobic exercise by measuring our own resting heart rate, and conduct scientific self-monitoring in combination with the adjustment of the treadmill's running speed or slope.
