Changes in major blood components influencing plasma osmolality during the long dehydration protocol.

Rest: baseline values, sampling time before exercise; 20’, 40’, …, 120’: sampling times at 20^th, 40^th, …, 120^th minutes of the exercise, respectively. VM: sampling time at the maximum power after 120 min preload; R5’ and R30’: sampling times at the 5^th and 30^th minutes of the recovery period, respectively. A major part of the osmolality is given by the change of sodium ions. To better represent visually the changes in the other components, we used an exponential magnification of the values, however, the numbers on the graphs show the actual values. The height of the columns and the numbers at the top indicate the changes in osmolality values.
