Wus good fellas,
I wanted to talk about recovery. More specifically, flushing.
As a personal trainer, I have my athletes flush thier muscle post workout to aid in quicker recovery. This is done via contrast bathes or ice massage. How it works is by limiting the blood flow using a cold modality then increasing blood flow using a hot modality. This flushes the old blood, toxin accumulated and gets new blood in and with new blood comes fresh oxygen and nutrients. This can be used as a cool down at the end of a routine our done prior to bed, whenever. Chronic and acute oxygen depletion is why your members turn black, blue, purple, lack of oxygen.
Guidelines for ice bathes are;
30 sec-2 min in ice water(could use cold pack) followed immediately by 2-3 mins in warm/hot water (hot pack). Repeat 2-3 times.
Ice massage; put a styrofoam/soft plastic cup full of water in freezer. When froze, take out and cut off 1/4 inch of top of cup. Massage in circular fashion for 5-15 mins.
*This guidelines are not specifically for pe, expirement.
Hopefully this helps, it pains me to see yall with something as simple to avoid as hypoxia. Remember, restricting blood to an area for too long will kill the tissue. Be careful and good luck everyone!
