Which of the following is NOT a factor in efficiency?
Which of the following statements BEST explains why the same exercise program might conform to the principle of overload for one person but not for another?
A goniometer measures __________.
Which of the following statements BEST explains why the standing long jump is a test of power?
Muscular strength is BEST described by __________.
Which object would have the most momentum?
Explain what distinguishes first class levers from second and third class levers.
First-class levers have the fulcrum between the effort and the load. Second-class levers have the load between the fulcrum and effort, while third-class levers have the effort between the fulcrum and load.
How are balance and stability different concepts?
Balance is the ability to maintain equilibrium by neutralizing the forces that disturb it. Stability, meanwhile, is the ability to maintain balance while participating in actions that are likely to upset balance. Standing on one leg for several minutes demonstrates good balance, while playing in a vigorous soccer game without tripping or falling demonstrates good stability.
Explain the difference between a joint's possible range of motion and its actual range of motion.
Each type of joint has a possible range of motion associated with it. This possible range of motion depends upon the type of joint it is, rather than the characteristics of the individual who possesses this joint. A joint's actual range of motion, however, is dependent upon the fitness levels of the individual. Since the possible range of motion is the theoretical maximal range of motion, the actual range of motion will always be less.
The measure of an object's mass and velocity is called __________.
Which of the following statements about joints is TRUE?
Which of the following BEST describes a body in equilibrium?
What differentiates extension from hyperextension?
Why should a good warm-up include stretching and activity-specific warm-up actions?
Stretching improves flexibility and range of motion; activity-specific movements activate the exact muscles and movement patterns used in the workout, enhancing performance and reducing injury risk.
When an object has its motion changed, the cause is generally __________.
Why are men typically less stable on their feet than women?
Women generally have a lower center of gravity than men, which contributes to greater stability. Men generally have more muscle mass in their upper arms and bodies, which raises their center of gravity and can make them less stable on their feet.
Explain why synovial joints have greater flexibility than fixed and cartilaginous joint.
Unlike fixed joints or cartilaginous joints, where the bones are connected by either connective tissue or cartilage, the bones in synovial joints are not directly joined by anything, which allows for a much greater range of motion.
How might being too strong actually restrict a joint's range of motion?
If excess muscle is too bulky it can interfere with the motion of a joint, which means that too much muscle strength can reduce a joint's range of motion and can actually reduce flexibility.
Explain the tangible physical benefits of warming up for and cooling down from a workout activity.
Warming up gradually increases body temperature, heart rate, and blood flow while loosening muscles and joints and preparing the body for exercise. Cooling down gradually lowers heart rate and breathing, keeps blood circulating, and helps prevent dizziness and blood pooling after the workout.
Explain why it's important to create a consistent schedule for your personal training plan.
A consistent schedule makes exercise a regular habit, helps ensure that all parts of the training plan are completed, and supports steady improvement while allowing adequate rest and recovery.
