Exercise Physiology
This equation states that oxygen consumption equals cardiac output multiplied by the arterial–venous oxygen difference.
What is the Fick equation/principle?
According to Newton’s second law, this quantity equals mass multiplied by acceleration.
What is force?
This professional organization manages the global Exercise is Medicine initiative.
What is the American College of Sports Medicine, or ACSM?
A relatively permanent improvement in the ability to perform a skill resulting from practice or experience.
What is motor learning?
Adults should accumulate at least this many minutes of moderate-intensity aerobic activity each week.
What is 150 minutes?
An RER value near this number indicates that fat is the predominant fuel being metabolized.
What is 0.70?
The rotational effect of a force about an axis, calculated as force multiplied by its perpendicular moment arm.
What is torque or moment of force?
Exercise is Medicine promotes assessing physical activity routinely in healthcare using this clinical measurement.
What is the Physical Activity Vital Sign, or PAVS?
Feedback describing the outcome of a movement, such as telling a golfer that the ball landed two feet left of the hole.
What is knowledge of results?
Adults should perform muscle-strengthening activities involving all major muscle groups on at least this many days each week.
What are two days per week?
During incremental exercise, this ventilatory variable initially increases proportionally with oxygen consumption but rises disproportionately after the ventilatory threshold.
What is ventilation, or Ve
During the lowering phase of a biceps curl, the elbow flexors perform this type of muscle action.
What is an eccentric muscle action?
The Physical Activity Vital Sign commonly asks patients how many days per week they perform moderate-to-strenuous activity and this second piece of information.
What is the average number of minutes performed on those days?
Practicing several skills in an unpredictable order creates this type of practice schedule and generally produces high contextual interference.
What is random practice?
Moderate-intensity exercise generally falls within this MET range.
What is 3.0–5.9 METs?
During exercise, an athlete has a heart rate of 150 beats per minute and a stroke volume of 120 mL per beat. This is the athlete’s cardiac output.
What is 18 L/min?
This mechanical quantity equals force multiplied by the time over which the force is applied and produces a change in momentum.
What is impulse?
A patient reports completing 40 minutes of moderate-intensity activity on three days each week. This is the patient’s weekly activity volume and the number of minutes by which it falls below the minimum aerobic guideline.
What are 120 minutes per week and 30 minutes below the guideline?
A temporary decline in performance when feedback is removed may indicate that the learner developed this excessive reliance on augmented feedback.
What is feedback dependency or the guidance effect?
Unlike earlier recommendations, the current federal guidelines no longer require physical activity to occur in bouts of at least this duration to count toward the weekly total.
What is 10 minutes?
Increased temperature, carbon dioxide, and hydrogen-ion concentration cause hemoglobin’s oxygen-dissociation curve to shift in this direction, facilitating oxygen unloading.
What is a rightward shift?
An external force of 400 N acts with a perpendicular moment arm of 4 cm about a joint. This is the magnitude of the external torque.
What is 16 N·m?
Beyond assessing physical activity and providing an appropriate prescription, Exercise is Medicine encourages healthcare providers to take this action when a patient needs additional exercise support.
What is refer the patient to an evidence-based program or qualified exercise professional?
According to Fitts and Posner, a performer who executes a skill consistently with minimal conscious attention has reached this stage of learning.
What is the autonomous stage?
A client has a resting heart rate of 60 bpm and an age-predicted maximal heart rate of 190 bpm. Using the heart-rate-reserve method, this is the target heart rate corresponding to 60% HRR.
What is 138 bpm?
