ExRx
This type of muscular fitness is defined as the ability to exert force over a long period of time (more than 20 repetitions).
What is muscular endurance?
This organ contributes to glucose output during exercise to prevent falls in blood glucose concentrations.
What is the liver?
The caloric requirement to break down one gram of lipids in the body.
The pacemaker of the heart, which sends electrical impulses through the heart's conduction system to cause heart beats.
What is the Sino-Atrial Node or SA Node?
These are the simplest forms of carbohydrates and include glucose, fructose, and galactose.
What are monosaccharides?
When creating a resistance training program, this type of muscle group exercise should be performed before exercises targeting smaller muscle groups.
What are multi-joint exercises?
This energy source provides the majority of carbohydrate energy during exercise.
What is intramuscular glycogen?
The term for long chains of carbohydrate molecules, like starch in plants or glycogen in humans.
What is a polysaccharide?
The term for smooth muscle contraction in the veins, which is stimulated by the SNS at the onset of exercise to direct blood to the heart.
What is venoconstriction?
The term that describes how muscle fibers have more than one nucleus, which makes them different to other cells.
What is multinucleated?
As people age, this condition, involving the loss of muscle mass, is slowed or reversed by regular resistance training.
What is sarcopenia?
The typical %VO2max at which lactate threshold occurs in untrained individuals.
What is 50-60%?
The recommended daily intake of protein for sedentary individuals with respect to body weight.
What is 0.8 g/kg body weight?
Resting cardiac output in L/min.
What is 5 L/min?
The most common muscle fiber shift in types occurs with increased training to become more aerobically efficient.
What is IIx to IIa?
This breathing technique, when performed during lifts, can lead to dangerous increases in pressure, cause fainting, and is not recommended for pregnant women.
What is the Valsalva maneuver?
This process increases when exercise intensity increases and helps release glucose for energy in the liver and muscles.
What is glycogenolysis?
The Dietary Reference Intakes committee recommends a diet that provides _____ percent of its calories from protein.
What is 10-35%
This law or mechanism describes how end-diastolic volume is proportional to stroke volume (i.e., how much blood is in the ventricles is proportional to how much blood is ejected).
What is the Law of Frank-Starling?
The term that describes the shift from fat to carbohydrate metabolism as exercise intensity increases.
What is the crossover concept?
This type of stretching is considered high-risk and is generally not recommended for non-athletes due to its rapid, bouncing motions.
What is ballistic stretching?
This term describes the ratio of expired CO2 and O2, which reflects gas exchange in the cell and can estimate whether carbs or fats are primarily being used for energy.
What is Respiratory Exchange Ratio or RER?
This condition is characterized by having too few healthy red blood cells, but it can easily treated because it is responsive to dietary changes.
What is iron-deficiency anemia?
This phase of the cardiac cycle occurs when the atria relax and ventricles begin to contract but before blood is ejected. The increase in pressure causes the AV valves to close.
What is the isovolumetric contraction phase?
This term describes how heart rate initially increases from rest to 100 bpm at the onset of exercise before the sympathetic nervous system further increases heart rate.
What is vagal withdrawal?
