This week, I got to take a trip to Randolph's very own dance studio with Brooke Freundlich. Every single movement the dancers made involved energy and muscle movement. I enjoyed very much watching the class, however, I couldn't help but notice how all the dancers seemed very sore. Their sore muscles are connected with their breathing patterns while performing. Dancers unfortunately have a very bad habit of holding their breath while moving, which restricts the amount of oxygen in the body. Because there is not enough oxygen, anaerobic respiration takes place. All the steps of respiration start to back up because the NAD+ and FADH "boats" cannot empty their electrons. Therefore, the electrons cannot get onto the ETC. The cells must result to fermentation to empty the "boats." Without the oxygen, lactic acid will build up in the dancer's muscles and cause soreness. Who knew that biology could explain sore muscles?!
