Chapter 23, Problem 18BS
Summary Introduction

To determine: The different ways by which an athlete could boost oxygen-delivering capacity and whether all methods shall be considered as ‘cheating’ and be banned.

Introduction: The cardiorespiratory system in the body plays an important role in delivering oxygen to muscles. Red blood corpuscles present in the blood contains a protein containing pigment that is hemoglobin. The hemoglobin has the capacity to carry oxygen and carbon dioxide. The hemoglobin carries oxygen to tissues and cells for oxidative phosphorylation at the end of which ATP is produced. The ATP produced in muscles will aid the athletes to make better use of their muscles in the sport they are competing in.

Since 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?
Riding a bicycle requires additional energy from leg muscles. Which of the following conditions may result from this activity, and which response helps restore the body to its normal condition? *       decreased oxygen can be replaced by digesting an apple. increased carbon dioxide in the blood can be removed by breathing faster. increased sugars in the bloodstream can be diluted by drinking water. increased salt wastes can be removed by the heart. No answer
Professional cycling has had much difficulty with cheating. Athletes and team doctors have discovered a variety of unnatural and illegal ways to improve sport performance. Cycling is highly aerobic which means oxygen is required to produce energy. If you have more red blood cells, you can carry more oxygen to working muscles. There are two methods of illegal blood doping to increase the number of red blood cells. 1. A few weeks before competition you would have some blood removed into a into a bag like when people give blood. You freeze the blood. Your body will pretty quickly replace the blood to normal levels. Before the race, you thaw and re infuse the blood. Now you (the athlete) have more than normal amounts of red blood cells. You can now carry more oxygen to yoru working muscles and have an unfair advantage. 2. You can also inject a hormone called erythropoetin (EPO) to stimulate the bone marrow to make more red blood cells. What two physiological systems are involved in method…
