Explain what distinguishes agility from balance and coordination.
Human muscles have an efficiency of about __________.
Which of the following is TRUE about assessing muscular strength and endurance?
The neck is a __________.
Explain the difference between mass and weight for objects on Earth and on the Moon.
Mass is the amount of matter in an object and remains the same on Earth and on the Moon. Weight is the force of gravity on the object, so an object weighs about one-sixth as much on the Moon as it does on Earth.
Explain how the components of skill-related fitness are interrelated and how each is of importance.
Compare and contrast the curl-up and arm hang test and explain why different tests cannot be used interchangeably.
Which of the following exercises would be BEST for improving muscular strength and endurance?
Describe the four main types of resistance forces.
The four main resistance forces are objects with mass, inertia, and momentum; friction; gravity; and air resistance. Objects with mass are able to provide resistance by colliding with other objects. Friction slows objects down by providing a steady resistance when the objects are in contact with and rubbing against a surface. Gravity provides a steady downward pull towards the center of Earth's mass. Air resistance is the cumulative force provided by millions of oxygen atoms being displaced.
The carpal bones in the wrist are an example of __________.
Explain the role that heredity plays in skill-related fitness.
Heredity affects a person's natural abilities and potential, which can influence skill-related fitness. Some people may inherit traits that give them an advantage in areas such as speed, coordination, or balance. Although heredity cannot be changed, regular practice and training can help people improve their skills.
Explain why the wall test is best considered a coordination test.
Grady has been playing soccer for years. He is considered an expert in many aspects of the game, including kicking, passing, and dribbling. How could Grady have achieved the status of expert?
Grady likely became an expert through years of consistent, focused practice. He repeatedly practiced kicking, passing, and dribbling, learned from feedback and mistakes, and used those skills in games. Over time, this helped him improve his technique and decision-making and perform the movements more automatically.
What two exercises could be used to increase your ability to perform push-ups in a fitness evaluation?
Distinguish between different kinds of cardiorespiratory fitness assessments and explain why different tests provide different information about fitness levels.
Cardiorespiratory fitness can be assessed with lab tests like direct VO2 max measurement on a treadmill or bike ergometer that give precise oxygen use data, or field tests such as the 1-mile run, 12-minute run, or step test that estimate fitness from performance time or heart rate recovery. Different tests provide different information because lab tests measure peak aerobic capacity directly while field tests assess sustained endurance or recovery under practical conditions, and each may target slightly different intensities or muscle involvement.
The time it takes to move in response to a stimulus is called __________.
Explain why it's important to create a consistent schedule for your personal training plan.
Explain what distinguishes first class levers from second and third class levers.
Any external force that acts against movement is called __________.
Describe the four main types of resistance forces.
The four main types of resistance forces are gravity, friction, air resistance, and water resistance. Gravity pulls objects toward Earth and can resist upward movement. Friction opposes movement between surfaces that touch. Air resistance opposes movement through air, while water resistance opposes movement through water.
