Hello students, the question says that your well hydrated light is running the music cd marathon during the year's race.
00:09
You notice that it is uncharacteristically warm, which is 90 degrees during that last half of the marathon.
00:20
Now the question is, list three physiological concerns you have associated with a rising core temperature which would reduce your performance.
00:32
The physiological concerns with rising core temperatures during a marathon in warm climate are there will be a sweat loss which is not fully replaced.
00:57
So if the sweat loss is not fully replaced, the individual's total body water will decrease.
01:24
Which means that the runner will feel dehydrated.
01:34
Because sweat is more diluted than plasma, dehydration from sweat loss results in increased plasma tonicity.
01:56
And hence decreased blood volume.
02:06
Both of which will act to reduce sweat and skin blood flow.
02:25
So as a result, the body's ability to dissipate heat will decrease.
02:42
And dehydration will result in a greater rise in core temperature during exercise heat stress.
02:56
In addition, the combination of an elevated core temperature and reduced blood volume will increase the circulatory strain...
