It definitely can, but it does not always occur. Depending on how your knees are shaped, standing with your knees bent for just 10 minutes can sometimes make you faint. If your knees are shaped a certain way, then locking your knees pinches a major artery just slightly, stopping a small amount of blood to stay in your legs instead of going to your brain. The longer you stand like that, the less oxygen goes to you brain. First you will feel woozy, then you might feel very nauseous, and then you wake up on the ground, wondering what happened. Just recently during a choir performance I, not knowing any of this yet, stood with my knees locked the entire time, because it uses less muscle. I felt like I was going to throw up, saw colors, and then I woke up on the floor with three other choir members trying to help me up.
No no no! Locking your knees while exercising in any way can cause joint problems and hyper-extension. Never lock your knees!
your feet turn red because all the blood in your body is going down to your feet, due to gravity, if you stand up to long with your knees locked you may pass out because the blood going to you brain lessons witch causes dizziness and lost of people pass out, EXAMPLE: people in wedding pass out all the time.....clue? they are locking their knees for to long........!
yes, it will. When you lock your legs it cuts off the circulation
Air locking windows are types of windows that do not allow air to pass through them. These are the types of windows that are normally used in aircrafts.
I had my knees locked for a while, and it hadn't even been one minute when I started feeling dizzy and passed put.
yes it has happened to me and was a none to pleasent expeirence
BECAUSE THEY ARE VERY NOISY LITTLE KNEES.
Yes. It is a completed pass if both knees are on the ground. The only situation that would make it an incomplete pass is if one or both knees were out of bounds. In college football, the play would be whistled dead and the line of scrimmage would be at the dead ball spot. In the NFL, if the receiver was not touched while in the process of making the catch, he is free to continue his forward progress until he is tackled. I have seen receivers roll while on the ground, and many times they dive or fall while making the catch and get up and run...
Joints make it possible for your knees and ankles to work.
You bend your knees , You hit with the flat part of both arms , get someone to show you .
If you keep them locked for long enough, you will pass out. You're restricting the natural flow of blood through your legs. Blood can pool in your lower leg and cause you to pass out.
