Concept explainers
a.
To determine: The similarities and differences between ATP, ADP, and PCr with respect to exercise.
Introduction: Skeletal muscles have smooth muscles cells present in them. The contraction of these muscles is the first process which takes place during exercise. Exercise is an active process which requires ATP as an energy supplement.
b.
To determine: The similarities and differences between myoglobin and hemoglobin with respect to exercise.
Introduction: Mitochondria are the “powerhouse” of the cell. The demand for energy increases during strenuous activity. This energy is produced with the help of oxygen, which enters into the mitochondria through globin proteins.

- Give an example of an aerobic traning exercise program using the FITT Principlearrow_forwardDescribe a simple Feldenkrais exercise that takes less than 5-minute and can be done while lying down. Please provide easy-to-follow steps.arrow_forwardSince humans began playing sports there have probably been people willing to cheat to gain an advantage. One form of cheating utilized by endurance athletes is called blood doping, which relates to our study of cellular respiration. “Blood doping is the misuse of certain techniques and/or substances to increase one’s red blood cell mass, which allows the body to transport more oxygen to muscles and therefore increase stamina and performance.” Definition from https://www.wada-ama.org/en/questions-answers/blood-doping From PED, to shaving points, bribery to drugging opponents (https://www.irishtimes.com/sport/maradona-backs-branco-s-claim-of-drug-laced-bottle-at-italia-90-1.4091470), there seems to be countless ways for athletes for gain an advantage. My question for the class is… What is the worst ethical offense that an athlete can commit? Do you know of any examples where this may have happened?arrow_forward
- The benefits of increased daily physical exercise include all of the following, EXCEPT: Question 14 options: providing a distraction to limit over-eating improving fitness levels and quality of life reducing insulin resistance in effector tissues burning an abundance of caloriesarrow_forwardThe Lactate (anaerobic) threshold Group of answer choices occurs at a higher intensity of exercise with endurance training is unchanged by endurance training is decreased following endurance exercise training is eliminated after aerobic exercise trainingarrow_forwardConsider Figure 49.3 in the textbook. Aerobic scope can be understood as an animal's capacity to increase its metabolic rate above maintenance levels so that they can perform physically demanding tasks. The following statements are true. Please choose all applicable options. a.Salmon performance is highly dependent on and sensitive to temperature changes. b.All salmon stocks have the same percentage of aerobic scope at any given temperature. c.All salmon stocks have a similar trend that relates temperature to their percentage of aerobic scope. d.As temperature increases, various salmon stocks have higher percentage of aerobic scope available to complete cardiovascular demands. e.As temperature increases, various salmon stocks have lower percentage of aerobic scope available to complete cardiovascular demands.arrow_forward
