a)Some competitive swimmers hyperventilate before a race, thinking they can “load up extra oxygen” and hold their breaths longer underwater. While they can indeed hold their breaths longer, it is not for the reason they think. Furthermore, some have lost consciousness and drowned because of this practice. is wrong with this thinking, and what accounts for the loss of consciousness? b) You cannot affect the oxygen delivery to your tissues by drinking “oxygenated water”.
