Is it true that “locking your knees” can cause you to faint? It is! But locking means more than just standing with your legs straight. It’s when your Quadriceps muscles in the front of your thighs are contracted enough to lift your kneecaps upwards, and held in that tightened position for an extended length of time.
Locking the knees can restrict blood flow through the veins, back to the heart, causing a depletion of oxygen to the upper part of the body, including THE BRAIN. Then….oops….thud.
If you stand to narrate, avoid locking your knees by keeping them softly bent and taking lots of breaks.
Reminder: Izotope RX doesn’t have THUD removal.
