Cardiovascular Physiology
This measurement of cardiac function is calculated by multiplying heart rate by stroke volume.
Cardiac output
A bone disease characterized by weak and fragile bones which occurs when the creation of new bone does not keep up with the loss of old bone.
Osteoporosis
What structure in the body detects rapid movement and initiates the stretch reflex?
Golgi Tendon Organ
What is the physiological variable that expresses the maximal rate at which oxygen can be taken up and utilized during intense exercise?
Vo2 Max
What year was ACSM founded?
1954
This heart structure possesses inherent automaticity, allowing it to initiate action potentials without external stimulation.
SA node
A chronic autoimmune disease where the body's immune system attacks insulin-producing beta cells in the pancreas.
Type 1 Diabetes Mellitus
What is the total ATP yield from the oxidation of one glucose molecule?
38
What principle states that training adaptations occur only when the body is stressed beyond normal levels?
Overload principal
During the sticking point of a 1RM bench press, bar velocity decreases due to a reduction in net joint torque primarily at this joint, caused by an unfavorable change in the internal moment arm of the prime mover.
Shoulder joint
These specialized junctions between cardiac muscle cells allow direct cell-to-cell transmission of action potentials, enabling coordinated contraction.
intercalated discs
Type of heart disease that occurs when the arteries supplying the heart become narrowed/ blocked due to buildup of plaque, reducing blood flow to the heart muscle. Symptoms include angina, dyspnea, and in severe cases myocardial infarction.
Coronary Artery Disease
What type of muscle fibers have the lowest capacity or aerobic-oxidative energy supply?
Type IIx
This fuel source is used the most during low-intensity, long-duration exercise.
Fat
Who is the president of SEACSM?
Kim Reich
This principle explains how increased ventricular filling leads to greater force of contraction due to optimal actin-myosin overlap.
Frank Starling mechanism
A pregnancy complication that typically occurs after the 20th week of pregnancy and is characterized by high blood pressure and proteinuria.
Preeclampsia
What adaptation increases muscle fiber cross-section without adding fibers?
Hypertrophy
This law states that healthy bones adapt to the loads under which they are placed, becoming denser and stronger to resist increased, repeated stress (functional loading) and weaker (atrophied) if loading is reduced or absent.
Wolfe’s Law
In a repeated sprint protocol (6 × 30-m sprints with 20-second recovery), performance decrement is most strongly associated with accumulation of this intracellular metabolite, which directly interferes with excitation-contraction coupling by reducing Ca²⁺ sensitivity at the myofilaments.
inorganic phosphate
This cardiac rhythm occurs when the AV node becomes the primary pacemaker after failure of atrial pacing.
Idiojunctional rhythm
A neurological condition that temporarily weakens or paralyzes facial muscles resulting in a droopy appearance on one side of the face. Typically occurs due to irritation or damage to the facial nerve. (CN VII)
Bell's Palsy
The longest aerobic endurance training sessions should be performed during which sport season?
Off-season
This hormone increases heart rate during exercise or stress.
Epinephrine
During prolonged endurance exercise at ~65% VO₂max in a trained athlete, hepatic glucose output is maintained primarily through this process once muscle glycogen becomes limited, mediated by increased glucagon-to-insulin ratio.
Gluconeogenesis
