Anatomy & Movement
The front of the body is known as.
What is anterior?
The three types of muscles.
What are smooth, cardiac and skeletal?
The three energy systems.
What are
ATP-PC (fast, short)
Anaerobic (moderate length, high intensity)
Aerobic (slow, long-lasting)
This hormone transports glucose to muscle cells.
What is insulin?
An effect of exercise that is short term.
What is acute?
The three body planes.
What are sagittal, frontal (coronal) and transverse?
Anatomy of a muscle:
Muscle > fascicle > muscle fibres > _______ > _______
What is myofibrils and sarcomeres?
This energy system uses glucose without oxygen and produces a burning sensation due to lactic acid.
What is the anaerobic glycolysis system?
To perform movement or exercise, muscles require these two things.
What is glucose and oxygen?
Building strength in your muscles is an example of this type of effect of exercise.
What is chronic?
Adduction moves the body towards this.
What is the midline of the body?
The two proteins inside of a sarcomere that make our muscles contract.
What are actin and myosin?
This energy system lasts the longest and uses both carbohydrates and fats with the help of oxygen.
What is the aerobic system?
The "hidden door" that allows glucose to enter the muscle.
What is GLUT4?
Define agonist and antagonist muscles
What is
agonist muscles = muscle doing the main movement
antagonist = opposite muscle relaxing or stretching?
The five types of bones.
What are long, short, flat, sesamoid and irregular?
When this mineral is released from the muscle it "unlocks" actin and myosin so they can slide past each other.
What is calcium?
The anaerobic system breaks down glucose without oxygen, what byproduct builds up in the muscles.
What is lactic acid?
Muscles produce these three types of waste during activity.
What is heat, lactic acid and CO₂?
Name and explain the energy currency the body uses.
What is ATP?
ATP has three phosphates. When energy is needed, ATP splits off one phosphate, becoming ADP. After ATP loses a phosphate (which gets USED to perform a task), it becomes ADP. ADP then recharges by adding a phosphate back to make it ATP again.
There are three major joint types. The one we are focused on is ________. And within this joint type, there are _____ type.
What is synovial and 6?
Explain sliding filament theory.
What is ... during contraction, myosin heads attach to actin filaments and pull them toward the M-line, shortening the sarcomere?
Endurance training affects the anaerobic threshold and energy system use during exercise because ...
What is it shifts the anaerobic threshold higher, allowing athletes to perform at higher intensities while still using the aerobic system efficiently?
When you improve your cardiorespiratory fitness, you gain this.
What is a stronger heart; more red blood cells; more capillaries; better mitochondrial function in muscle cells?
During a sprint, this energy system kicks in first. It powers the quadriceps [concentrically or eccentrically], while the hamstrings act [concentrically or eccentrically], and the knee moves in the [sagittal, frontal (coronal) and transverse] plane.
What is the ATP-PC energy system; concentrically; eccentrically; sagittal plane?
