Lifetime Fitness

True.

Exercise is important because of its positive effects on all the body's systems. In addition, regular exercise reduces the risk factor of contracting many diseases.

The various components of wellness often influence one another. A good example is how poor body composition may affect your willingness to meet new people, thus negatively affecting your social health.

Physical activity is the movement of large muscle groups through daily activities

Physical fitness isn't something you achieve and forget about. Instead, it's a challenge we face each and every day. Your physical fitness is the sum of all the choices you make.

Exercise is a subset of physical fitness.

Wellness is related to our achievement in each of the components of health. To achieve true wellness, we should be doing our best in all six of these components. Like physical fitness, wellness is a dynamic concept; we must always work for our wellness.

In addition to using protective equipment correctly, participants must also follow the game rules, use common sense, and keep the safety of others in mind.

There are several key factors to consider when selecting workout clothing. Comfort is a big factor. You don't want to choose clothing that is uncomfortable. The way the clothing fits is also important. Workout clothing tends to be smaller so it's important to choose clothing that allows for a wide range of motion. Wicking, which is the ability of fabric to help remove sweat from the body, is better than plain cotton. Layering is another factor to consider because you want to have clothing that can be easily layered in the colder months. You should also consider whether or not the clothing is technologically advanced and whether or not it is activity appropriate.

Protective equipment is designed to prevent the common injuries that can occur for each sport. While protective equipment does not completely eliminate the chance for injury, it does significantly reduce the risk.

In general, you can choose when, where, and how to exercise. Each of these choices can either positively or negatively affect your safety during physical activity.

While exercising, the body loses fluids through perspiration and respiration. The more rigorous the exercise, the more fluids are lost. It's important to replace these fluids both during and after the exercise.

in both cases, the common preparation steps are allowing the body to acclimate gradually to the temperature and wearing appropriate clothing.

Heat exhaustion and heat stroke are both caused by prolonged exposure to the Sun with very high temperatures. Heat exhaustion is typically less severe with symptoms of headache, nausea, pale skin, and fatigue. Heat stroke results when the body cannot regulate its body temperature any longer, and it is life threatening. Immediate medical assistance should be obtained if you suspect heat stroke.

The cycle of fluid intake and loss continues on a daily basis. Fluid intake is accomplished by drinking fluids and eating foods. Fluid losses occur through urination, perspiration, and respiration.

Agility, balance, and coordination each refer to different fitness skills. Agility refers to the ability of executing rapid changes in any direction. Balance refers to the ability of moving while remaining upright. These two skills are related, but still distinct. Dodging back-and-forth in a sports game is an example of good agility, while moving around without slipping or falling is an example of good balance. Coordination, meanwhile, is the ability of using different body parts together in concert. An example of coordination is running down the length of a football field while passing the ball to another player.

The wall test involves throwing a ball against a wall with one hand and catching it with the opposite hand as it bounces back. It measures the ability of using different body parts in conjunction with one another. While reaction time is somewhat a factor, it is a repetitive, pattern behavior test that makes good coordination a more important factor than agility, power, or speed.

False.

Levers are tools that allow a small effort to move significantly larger loads. This apparent magnification of the force applied to a lever, and the force resulting from it, is called its mechanical advantage.

Mass is a measure of an object's inertial force, or how much it resists motion, and of the amount of matter in it. Weight is the measure of gravity's pull on objects. Mass is independent of gravity, so the mass of an object will be the same on both Earth and the Moon. Because weight is dependent upon gravity, and the Earth has a greater force of gravity than the Moon, an object on the Earth will weigh more than it will on the Moon.

The seesaw is a long lever arm with the load at one end, the effort at the opposite end, and the fulcrum in the center. With both the second and third class levers, however, the fulcrum is at one end of the lever and both the load and effort are on one side of the fulcrum. The seesaw is closest in arrangement to a first class lever because it is the only class of lever with the fulcrum between the load and effort.

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.

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.

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.

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.

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.

The larynx is also called the voice box. While its main function is to allow a person to speak, it also protects the trachea.

Generally, many cardiovascular diseases are related to lifestyle behaviors. Factors that contribute to the development of cardiovascular disease include lack of a balanced diet, lack of exercise, smoking, and the lack of regular doctor visits.

Stroke

The lungs need to remain elastic so they can effectively move oxygen into the body and carbon dioxide out of the body. By smoking, you are actually introducing carbon monoxide into the body, which is toxic. Tars and other chemicals will settle on the cilia of the lungs and cannot be removed; which further degrades the functionality of the respiratory system. Two conditions that develop when a person smokes are emphysema and bronchitis.

The heart is a muscle, and as with all muscles, it needs to be strengthened in order to maintain optimal health. The best way to strengthen the heart is to exercise it by performing activities that elevate your heart rate and increase blood flow.

Arteriosclerosis is a general term for the hardening of arteries and a loss of elasticity in arterial walls. Atherosclerosis is specifically a condition where arteries harden as a result of plaque buildup on artery walls. Both conditions result in poor and inefficient blood flow through arteries, which can lead to blood clots or ruptures in the blood vessels of the heart or brain. Blockages in the heart can result in heart attacks; blockages and ruptures in the brain lead to strokes

All of these conditions can be treated by thinning the blood. In each case, lowering blood pressure helps reduce the symptoms, and some of the best medications for lowering blood pressure do so by thinning the blood.

Both strokes and heart attacks occur when the blood supply to that part of the body is blocked or interrupted. Strokes occur in the brain, while heart attacks are specific to the heart muscle. Both can be caused when blockages cut off the blood supply and the tissues starves for oxygen and other nutrients. Strokes can also occur when the pressure in a blocked artery causes it to burst and the blood leaks into the brain.

There is no single step for preventing cardiovascular disease; all aspects of a healthy lifestyle impact cardiovascular fitness. Eating a healthy diet can reduce your dietary cholesterol and help maintain a healthy body weight. Getting regular exercise can also help maintain a healthy body weight as well as strengthen the heart muscle. Avoiding smoking is another part of a healthy lifestyle that can significantly reduce the risk of developing cardiovascular disease.
