Males vs. Females
- Females have a higher Heart rate than those of men at max.
- Their stroke volume is lower than that of men at max
- Their cardiac output is lower than men at max.
Young vs. Old
- Older people do have a slightly higher cardiac output than children.
- Children have a higher over all heart rate and lower stroke volume
- Adults have lower heart rate but higher stroke volume
Trained vs.
Untrained
- A trained person has a higher cardiac output than a untrained person
- The trained resting heart rate is lower at rest but same at max
- The stroke volume is always higher for a trained
This is such a creative and refreshing way to tackle a complex topic! Your mnemonics and analogies (especially the clock resistance trick!) make these physiological concepts so much more approachable. The way you break it down into three key variables cuts through the intimidation factor perfectly.
ReplyDeleteLove how you emphasize that it's all about pattern recognition—hypereffective vs. hypoeffective heart, MSFP changes, and resistance shifts. The hemorrhage example really ties it together clinically. Your enthusiasm is contagious ("It's a RAP!" got me laughing while learning).
The offer to draw custom examples is incredibly generous—this kind of engaged teaching is what makes tough topics stick. That linked reference is gold too! More educators should take notes from your "simple & easy" philosophy. Keep these brilliant memory aids coming! we also write about it here multivit.us
