Sasha has been working out for a few months now. She has a schedule that requires her to go to the gym every day. Lately, she noticed that her blood pressure is up and she is feeling irritable. What action would benefit her the most?
Explain how Newton's law of inertia describes the motion of objects.
Newton's law of inertia states that an object at rest stays at rest, and an object in motion continues moving in a straight line at a constant speed, unless a net external force acts on it.
The BEST weight to use for weight training in order to increase strength is one that __________.
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.
How might being too strong actually restrict a joint's range of motion?
Excessively large or tight muscles around a joint can block movement or limit flexibility. If the muscles are shortened or cannot lengthen enough, they may prevent the joint from moving through its full range of motion.
If asked to give your friend advice about a muscular fitness program, the most accurate response would be that __________.
When comparing an individual with low muscular fitness to an individual with high muscular fitness, we would very likely find that __________.
Why are men typically less stable on their feet than women?
Men typically have more upper-body mass, giving them a higher center of gravity. A higher center of gravity generally makes it harder to maintain stability, so men may be less stable on their feet than women.
Which principle of exercise is concerned with maintaining a challenging workout?
Describe four ways in which improving your muscular fitness would have a positive affect on your life.
Improving muscular fitness can lead to: 1) better posture and reduced back pain, 2) lower risk of injury during daily activities, 3) increased metabolism and easier weight management, 4) improved performance in sports and physical tasks.
Why are muscle and fat levels the only factors influencing flexibility impacted by personal decisions?
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.
