What did this day actually feel like?
Bioethics: performance enhancement
ETHICS DAY Should athletes be allowed drugs that build muscle faster? I said no and got asked why training at altitude is fine but a drug is not, since both are deliberate manipulation of physiology.
I did not have a clean line. The best I got to was that one carries a health cost the athlete may not be able to refuse if everyone else is taking it. That is a coercion argument, not a fairness argument, and it is a better one than what I walked in with.
AT HOME, THE NIGHT BEFORE TUE FEB 23 Sarcomere and contraction The sarcomere. Actin and myosin, Z-lines, A-band, I-band, and the sliding filament model.
Every voluntary movement you have ever made is filaments ratcheting past each other. The muscle does not contract by shrinking, the filaments slide across each other and the whole thing gets shorter. I labeled the diagram three times before the bands were in the right places.

- • This week we study the muscular system from the to the full muscle. Before we do that, we have a question this system raises directly.
- • Drugs that force muscles to grow faster are real, available, and banned in most sports. Should they be?
- • Your CER today must take a specific position. Not just that drugs are bad. A position on the fairness and health trade-off.
- • Listen for the term anabolic in the reading. That word connects to the muscle biology we start tomorrow.
- • Anabolic steroids mimic testosterone and increase muscle synthesis, but side effects include cardiovascular damage, hormonal disruption, and liver toxicity.
- • The fairness argument against enhancement centers on coercion: if some athletes use drugs, others feel forced to do so to compete.
- • Bioethical reasoning requires weighing physical autonomy (right to use) against health harm and competitive equity.

What the evidence supports: E1-E3 and F1 support the daily take-home when the response meets the stated success criteria.
What it cannot prove: The package does not support claims beyond this lesson's or any real patient diagnosis.
- • : The basic contracting unit of a muscle fiber, made of overlapping and filaments that slide past each other to shorten the muscle.
- • : A that forms thin filaments inside cells and slides past to produce muscle and cell movement.
- • : A motor in muscle whose heads grab and pull on filaments, producing the sliding motion that contracts the muscle.
- • : The shortening of a muscle as its fibers pull together, generating force to move bones, pump blood, or squeeze organs.
- • : A tough band of that anchors a muscle to a bone, transferring the muscle's pull so the bone can move.
- • origin: The fixed, anchoring attachment point of a muscle on a bone, which stays still while the muscle pulls on its other end.
- • : The end of a skeletal muscle attached to the bone that moves when the muscle contracts, as opposed to the more fixed origin end.
- • lever: A rigid bar that pivots at a fixed point to move a load, the simple machine that bones, joints, and muscles form to create movement.

PLTW-HAP-2027-02-19 · Simulated classroom evidence scenario
Your role: anatomy and physiology consultant
Decision: Your team must decide what the evidence from Bioethics: performance enhancement supports before submitting the claim-evidence-reasoning response named on the lesson page.
- • Select the option best supported by E1-E3.
- • Select a reasonable alternative and name the evidence it would require.
- • Delay the claim because the evidence does not distinguish the options.
Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the claim-evidence-reasoning response.
Claim ceiling: The supplied lesson evidence can support an observation, pattern, classroom mechanism, or next-step decision about Bioethics: performance enhancement. It cannot by itself prove causation, establish a real clinical diagnosis, or justify action outside this classroom task.
Reason for review: Your team must decide what the evidence from Bioethics: performance enhancement supports before submitting the claim-evidence-reasoning response named on the lesson page.
Context: Anything that changes how muscle works also changes the whole body, so a choice that helps performance can harm health and fairness at the same time.
- • T1: Read the prompt: should athletes be permitted to use drugs that build muscle faster?
- • T2: List two arguments for allowing enhancement and two for banning it.
- • T3: Choose a side and write a one-sentence claim with your reasoning.
- • T4: Debate in your John Carroll bioethics group and note the strongest opposing point.
- • T5: Post a CER response on fairness and health in enhancement.
- • E1: Anabolic steroids mimic testosterone and increase muscle synthesis, but side effects include cardiovascular damage, hormonal disruption, and liver toxicity.
- • E2: Performance-enhancing drugs change muscle physiology through real pathways, so they create health risks and fairness problems at the same time and cannot be judged on winning alone.
- • E3: You can defend a position on muscle-enhancing drugs.
Measurements: Use only the measurements, units, graph, or counts supplied in today's task. No additional patient measurement is implied.
Figure finding: Teaching diagram for Bioethics: performance enhancement. Trace the labeled structure, movement, or system relationship that connects form to function. This is a teaching model, not patient or experimental data.
Uncertainty: This is a composite classroom scenario. Missing history, measurements, or confirmation tests remain unknown and limit the conclusion.
Mean = sum of values / number of values. Median = middle ordered value. Range = maximum - minimum.
For 2, 4, 4, and 10: mean = 20 / 4 = 5, median = 4, and range = 10 - 2 = 8.
Mean, median, and range keep the measurement unit. Order the values before finding the median.
Calculate the requested summary for today's supplied values, then write what it reveals and what it hides.
Students often think Students often think steroids are dangerous only because they are cheating, so a 'clean' or legal version would be safe.. The trap: The danger is biological, not just legal. Anabolic steroids mimic testosterone and push muscle synthesis, but the same signal also thickens the heart and disrupts the body's own hormone production, so making them legal would not remove the cardiovascular and liver harm.
Claim: Students without a medical diagnosis should not be permitted to use prescription stimulants such as amphetamine drugs to boost their performance on exams.\nEvidence: Prescription stimulants raise the level of dopamine and norepinephrine in the brain, which can increase short-term alertness and focus. In people without a condition like ADHD, though, they also carry documented risks including raised heart rate and blood pressure, disrupted sleep, anxiety, and the potential for dependence. On top of the health risks, if some students take a pill to stay sharp during a high-stakes test, other students feel pressure to do the same just to keep their scores competitive.\nReasoning: Allowing non-medical stimulant use creates a coercion problem that looks a lot like other enhancement debates: students who would rather not take a drug are pushed to risk their health so they are not left behind. Because these stimulants cause real physical and psychological harm in people who do not need them, and because they turn a test of preparation into a test of who is willing to medicate, restricting non-medical use protects both student health and the fairness of the assessment. That combined harm outweighs an individual student's claim to use whatever they want to get an edge.\nCounter-argument I heard and my response: A classmate argued that students are old enough to make their own choices about their own bodies. I agree that personal autonomy matters, but in a shared, graded setting one student's choice raises the bar for everyone else and forces a health risk onto peers who never wanted it. Because the harm spills over onto others and the drug carries real dangers, the fairness and safety concerns justify the restriction.
This model shows the level of evidence and organization needed to complete: A short claim-evidence-reasoning post that models the format on a parallel bioethics case, whether students without a prescription should be allowed to use stimulant drugs to boost test performance, so students can see the depth and structure without seeing an answer to today's own sports-doping question.
