Re-training only practices the upper body to cause blood vessels to become hardened? Professor Analyzing Japanese Studies

Reader inquiry:

Hello Professor Lin, I am a enthusiast of training, but I recently saw an article saying that training on the upper body will cause blood vessel sclerosis? ? I don't know if this is true. I'll help you to help me and thank you!!

Retrieve the text: In recent years, people have raised their health awareness and have brought about a trend of fitness, but some people only pay attention to local training. According to the survey, nearly 50% of male college students only train their upper body. However, according to the Japanese study of healthy young people with 20 years old, a pure upper limb weight training will stimulate the secretion of orthogonal epinephrine, which promotes blood vessel contraction and blood pressure in a short period of time. Compared with lower limb weight training, the risk of vascular sclerosis will increase by 2 times. In addition, inappropriate force application or short-term stress during the effort may cause vascular embolism.

{Although this article mentions "Japanese research on healthy young people at the age of 20", it does not provide verified papers, and although its remaining paragraphs refer to professors from a certain university, it still does not provide any verified data. Therefore, such articles are actually difficult to convince people.

I went to the public medical library to search and found a "Japanese research". It was published in 2007 and the title is

Resistance training in men is associated with increased arterial stiffness and blood pressure but does not adversely affect endothelial function as measured by arterial reaction to the cold pressor test.

This study was done by the Japanese, and it was found that male resistance training is related to the stiffness of the veins and the increase in blood pressure, so it should be the "Japanese research" mentioned in that article. However, it is unfortunate that in this study, male resistance training is systemic, not what the article said “only doing upper limb weight training”. So, I have to wonder if the "Japanese research" mentioned in that article is true. If you have any, please put it on the tiles.

No matter what, although the "Japanese study" I found in this article found that male resistance training is related to increased stiffness of the veins and blood pressure, it also found that male resistance training does not affect vascular function. Therefore, the researchers also said this specifically: "Given these functional and physical benefits of resistance training, we should emphasize that the practice of resistance training should not be disclosed." Also, this study only examined 12 men who did resistance training, so it was difficult to make a conclusion like this, saying that resistance training can cause vascular sclerosis and blood pressure to rise.

"As long as you have a big chest muscle! 50% of male students only train their upper body after training." I feel the same way. In sports clubs, I often see young people with naked upper body, twisting their shoulders and chest against the lens, looking like they love themselves. Although it's funny, it's completely understandable. After all, the chest muscles are a sign of the male body. However, having large chest muscles does not mean that your body is healthy. I once saw a young man with big chest muscles jogging on a jogging machine and couldn't take it for two minutes. This means that he is too focused on practicing the chest muscles and ignores the more important cardiopulmonary function.

I have said in what is the best movement, that sports are best (1) continuous, (2) balanced, and (3) suitable for strength. I also quoted a Harvard University doctor in the necessity of gravity training, saying that just doing aerobic exercise is not enough; unless you are doing gravity training, you will become weak and lack function. Therefore, I have always been alternating gravity training and physical training.

The purpose of that article is good, but it says that "the risk of vascular sclerosis will increase by 2 times compared to lower limb weight training, which may cause vascular embolism." I am afraid there is no scientific evidence.
