Submaximal Response to Exercise
- How safe is exercise? Of the young athletes who die of sudden cardiac death, what are the likely causes? Can exercise be blamed?
- Explain the purpose of risk stratification. Describe low, moderate, and high risk.
- What assumptions have to be made in order to predict VO2max from the HR of submaximal exercises?
- Explain how hypertension pathologically thickens the heart.
- What is the most important factor that contributes to resistance of blood flow?
- Explain the YMCA Cycle Ergometer test (stages, duration, intensity, etc).
- According to the YMCA test, what are the predicted VO2max of our subject’s (attach the figure when turning in the lab)? Are they within normal, healthy ranges given our subject’s age and sex?
- How does the value you predicted this week compare to the value you measured when you used the metabolic cart and had your subject exercise to volitional fatigue? Why might it be different?
Submaximal Research Article Questions
The purpose of this article was to determine the effects of environmental temperature on physiological responses and endurance exercise capacity during submaximal and maximal exercise in a healthy adult population. Although there has been much research supporting the understanding that thermoregulation is effective in regulating body temp under normal conditions, submaximal and maximal exercise in extreme cold and heat exerts far more stress on the mechanisms that help regulate body temperature. The present study examined thermoregulation during submaximal oxygen uptake and maximal oxygen uptake under three different environmental temperatures (extreme cold, moderate, and extreme heat) at the same humidity.
In this week’s research article, the present study’s findings of physiological responses and endurance exercise under extreme environmental conditions suggests that environmental temperature conditions play an important role for exercise performance. Based on that information…
- What was the purpose of this study?
- Describe why this test used three different environmental conditions to evaluate physiological responses to endurance exercise.
- Having learned about maximal oxygen uptake and predicting maximal oxygen uptake during submaximal exercise, if we re-ran this weeks lab in the environmental chamber and created an extremely hot temperature, how would that affect your subjects exercise capacity and predictive maximal oxygen uptake?
- The present study evaluated submaximal exercise and a time to exhaustion bout (maximal exercise). Describe the differences shown from this study of endurance exercise capacity (submaximal and maximal) in normal and extreme environmental conditions. What physiological responses does our body enact under these different environmental conditions?
