Body's response to exercise ๐โโ๏ธ
- The body adjusts various systems in response to exercise.
- Our exercise capacity varies based on how hard these systems are pushed.
- Think about it: Have you ever seen someone sprint the length of a marathon? Nope! That’s because of the body’s limits.
What's VO2max anyway? ๐ฌ๏ธ
- VO2max: the maximum amount of oxygen one can use.
- How's it measured? By checking the air we breathe out during increasing exercise intensity.
- Imagine trying to blow up a balloon bigger than its capacity. At some point, it won't inflate any further. That's similar to reaching your VO2max.
Why care about VO2max? ๐ค
- VO2max = Aerobic Capacity
- Important for two extreme groups
- Severely limited patients (Low VO2max)
- Elite endurance athletes (High VO2max)
- Example: An elite marathoner can run super long distances because of their high VO2max, but someone with health issues might find a short walk challenging.
The fick equation ๐
- Links VO2max, maximum cardiac output, and maximum arterio-venous oxygen difference.
- VO2max = Maximum cardiac output x Maximum arterio-venous oxygen difference
Training adapts our body ๐ช
- Endurance training results in
- Improved blood flow.
- More capillaries around muscle fibers = better oxygen supply!
- Kids vs. Adults? Kids have smaller hearts, so their cardiac output is lesser. But they compensate by using oxygen differently.
