Solved in 3 steps
- Do you get dehydrated when engaged in dance activities? Explain why.Discuss the term dehydrationAn athlete is sweating profusely but does not rehydrate. The changing conditions are detected by osmoreceptors in the hypothalamus.Select the four conditions associated with loss of water and the response it triggers. Increased solute concentration Decreased solute concentration Increased blood volume Decreased blood volume Increased blood pressure Decreased blood pressure Increased release of ADH Decreased release of ADH
- caffeine is also diuretic, which means it increases the movement of water through the kidneys into the urine. Why would this potentially offset its value to a distance athlete?Why does the risk of dehydration increase as people age? no handwritten answers please,Steven is a 35 year old male. To gain a better understanding of fluid requirement, you have decided to calculate his hourly sweat rate. You have collected the following data: · Exercise duration: 2 hours· Pre-exercise body mass: 85kg· Post-exercise body mass: 82.5kg· Fluid consumed during exercise: 350mL· Urine loss during exercise: 50mL From this data, what is his hourly sweat rate? Based on this, how much fluid should he consume during training?
- This summer, Sam is training for a marathon by running 10 miles a day. Describe changes in his fluid balance as he trains.An athlete is sweating profusely but does not rehydrate. The changing conditions are detected by osmoreceptors in the hypothalamus.Select the 4 conditions associated with loss of water and the response it triggers. Increased solute concentration Decreased solute concentration Increased blood volume Decreased blood volume Increased blood pressure Decreased blood pressure Increased release of ADH Decreased release of ADHGout—a condition that results in joint swelling and pain—is caused by the formation of sodium urate (NaC5H3N4O3) crystals within tendons, cartilage, and ligaments. Sodium urate precipitates out of blood plasma when uric acid levels become abnormally high. This sometimes happens as a result of eating too many rich foods and consuming too much alcohol, which is why gout is sometimes referred to as the “disease of kings.” If the sodium concentration in blood plasma is 0.140 M, and Ksp for sodium urate is 5.76 * 10 - 8, what minimum concentration of urate would result in precipitation?
- Metabolic alkalosis refers to a process whereupon decreased hydrogen ion, or increased bicarbonate, concentrations occur in the body, and the blood pH becomes too basic. Answer the following questions: How does the body regain its acid-base equilibria/balance? What happens when that balance does not happen? Will a buffer system still work under these conditions?Solutions conduct electricity, if there are charged particles or ions present. Our body contains ions, too. Thus, solution containing ions are called electrolytes. Why do you feel thirsty after playing or working outside? Sometimes, you suffer from cramps or headaches, in extreme cases, you may even experience vomiting and nausea. These are symptoms of electrolyte imbalance in the body. Suggest ways or recommendations that can be given to a person who experience electrolyte imbalance.Why is a sport drink more effective than plain water for rehydration after extended exercise?
