Hello. I'm YAYA â½, a strength reporter for YakAl..

I thought this winter would pass warmly, but the snow and cold weather just keep coming..

This kind of weather is perfect for catching a cold.,

So what should we eat to prevent a cold??

As you can see from the title, the answer is 'protein supplements.'.

Wait, on days like this, shouldn't a man fight fire with fire and eat ice cream to prevent colds?,

Why protein supplements, you ask??

Let's set off with me now to find out why you need to take protein supplements to prevent colds!?

The experiment was conducted for 12 weeks with male college students in their 20s (7 in the experimental group, 7 in the control group)..

All experimental subjects performed resistance exercise, and then

the 7 subjects in the experimental group consumed 1.8g/kg of protein supplement divided into 4 doses per day:

in the morning on an empty stomach (0.3g/kg),)
30 minutes before exercise (0.6g/kg),)
immediately after exercise (0.6g/kg),)
and 1 hour before bedtime (0.3g/kg)..

Body weight showed no significant difference between groups before and after resistance exercise, and body mass index also showed no significant difference..

Subsequently, through blood analysis of the experimental subjects, anabolic hormones, catabolic hormones, IgG, IgA, IgM, and WBC (white blood cell count) were measured..

What were the results??

The difference in WBC between groups was not significant (p>0.5),),

but IgG and IgM showed significant differences between groups (p<0.5))..

IgM enhances red blood cell aggregation and hemolysis, promoting immune response by preventing inflammation and increasing resistance,,

and while it has been reported to decrease in resistance exercise groups after high-intensity training,,

protein supplementation was shown to be effective in increasing IgM production..

IgG enhances resistance to infection,,

and while it decreases in resistance exercise groups, it showed an increase with protein supplementation..

Additionally, a correlation between insulin and IgG was confirmed..

Insulin plays an important role in anabolism, such as stimulating protein synthesis,,

and it was found that as insulin increased, the change in IgG levels also increased..

So far, we've examined the relationship between protein supplements, exercise, and immune function..

With exercise alone, IgG and IgM levels decreased,,

but when combining exercise and protein supplements, the levels increased..

But what if you only take protein supplements? You're curious, aren't you??

The answer is! You can find out with YakAl's YAYA..

Please look forward to my next article on protein supplements!!

Conclusion

If you exercise without taking protein supplements (without consuming enough protein), your immune function decreases..
If you exercise and take protein supplements (consume enough protein), your immune function increases..
