This thigh bone—the largest, heaviest, and strongest in the human body—articulates with the pelvis to form the hip joint.
Femur
The formula for cardiac output
Q = HR * SV
Bicep curls and leg extensions are classic examples of this type of joint movement, which decreases the angle between two articulating bones along the sagittal plane.
Flexion
What is the organization principle using progressive cycles of various aspects of training programs to vary volume and intensity
Periodization
This pathway breaks down fatty acids
Beta oxidation
The basic structural and functional contractile unit of a muscle myofibril, bounded on either end by a Z-disc
sarcomere
This specific point during incremental, graded exercise is marked by a sudden, systemic elevation in blood lactate concentration above resting baseline levels
Lactate threshold
During a squat, your quadriceps undergo an eccentric contraction while descending, followed by this type of muscle contraction as they generate force while shortening during the upward ascent.
concentric contraction
The current ACSM recommendation for moderate intensity exercise for healthy adults
At lest five days per week, totaling at least 150 minutes per week
In anatomical position, this directional term describes where the carpals lie in relation to the metacarpals.
Proximal
What type of summation refers to multiple nerve impulses over time
This immediate, anaerobic energy system provides the primary source of ATP for short, explosive bursts of maximal exercise lasting up to 10–15 seconds,
The Phosphagen System (or ATP-PCr / Creatine Phosphate System)
This neurotransmitter is released at the synaptic cleft
Acetylcholine (ACh)
The term used to describe how much work can be accomplished in a specific period of time (dependent on both the force generated and the velocity of movement)
Muscular power
This skeletal muscle fiber type is characterized by a high concentration of myoglobin, high mitochondrial density, rich capillary supply, and high resistance to fatigue
Type I fibers (or Slow-Twitch / Slow Oxidative fibers)
This tarsal bone sits directly superior to the calcaneus, forming the lower portion of the talocrural joint by articulating with the tibia and fibula.
talus
What’s the rate limiting enzyme of glycolysis?
Phosphofructosekinase(PFK)
This type of summation refers to multiple nerve impulses over time
Temporal summation
A client is working at a steady-state oxygen consumption level of 35 mL/kg/min. How many METs (Metabolic Equivalents) are they expending?
10
Founding director of the Harvard Fatigue Laboratory

As the only muscle in the quadriceps group that crosses two joints, this muscle originates at the anterior inferior iliac spine and extends the knee while flexing the hip.
Rectus femoris
Increased H+ created during exercise is buffered by this substance to form carbonic acid (H2CO3),
Bicarbonate (HCO3-)
Calculated as the product of force applied and the perpendicular distance to the pivot point, this mechanical vector quantifies the rotational force generated around an axis of rotation.
Torque
Under current ACSM risk-stratification, a client who currently exercises regularly, is asymptomatic, and wishes to transition to vigorous-intensity training requires what clearance step?
Medical clearance is not currently needed
This classic physiological effect describes a rightward shift of the oxyhemoglobin dissociation curve, decreasing hemoglobin’s affinity for oxygen and enhancing O2 unloading at active skeletal muscles
The Bohr effect
