Fit For Life Final Exam Murdock 2014

The answer "one completion of an activity or exercise" is correct because a rep, short for repetition, refers to the completion of a specific movement or exercise. It represents a single instance of performing a particular activity or exercise, such as lifting a weight or doing a push-up. Each time the activity or exercise is fully executed, it counts as one rep. Therefore, the correct answer accurately defines what a rep represents in the context of physical fitness or exercise.

The correct answer is "degrees of motion allowed around a joint." This is because the range of motion refers to the extent to which a joint can move in various directions. It is measured in degrees and indicates the flexibility and mobility of the joint. The other options are not accurate definitions of range of motion.

Hemoglobin is an iron-rich compound in the blood that helps carry oxygen. It binds with oxygen in the lungs and releases it to the tissues throughout the body. This process is essential for the transportation of oxygen from the lungs to the cells, ensuring proper oxygenation and functioning of the body.

Heredity refers to the passing of genetic traits from parents to their offspring. It is not something that can be modified or changed. Genetic traits are determined by the DNA that individuals inherit from their parents and cannot be altered. Therefore, heredity is not a risk that can be modified, making the statement false.

The heart is considered the most important muscle of the body because it is responsible for pumping blood throughout the entire circulatory system. This continuous pumping action ensures that oxygen and nutrients are delivered to all the organs and tissues in the body, while also removing waste products. Without the heart's constant and efficient functioning, the body would not receive the necessary oxygen and nutrients to survive. Therefore, the heart plays a vital role in maintaining overall health and well-being.

The human body has more than 600 skeletal muscles. These muscles are responsible for various movements and functions in the body, such as walking, running, lifting, and even breathing. Skeletal muscles are attached to bones and work together to provide stability, support, and movement to the body.

If someone is suffering from heat stroke, it is important to call 911 for immediate medical assistance. Heat stroke is a severe condition that occurs when the body overheats and is unable to regulate its temperature. It can be life-threatening and requires prompt medical attention. Calling 911 ensures that trained professionals can provide the necessary medical care and transport the person to a hospital if needed. Therefore, it is crucial to call 911 if you suspect someone is experiencing heat stroke.

The risk of unintentional injury is greater with free weights compared to weight machines. Free weights require more control and stability from the user, as they are not fixed in place like weight machines. This increased freedom of movement can lead to accidents if proper form and technique are not maintained. Additionally, free weights can cause injury if dropped or mishandled. Weight machines, on the other hand, provide a guided range of motion and often have safety features in place to minimize the risk of injury.

The correct answer is frequency. The question is asking for the term that describes how often someone works out. Frequency refers to the number of times something occurs within a given time period. In this context, it relates to the regularity or consistency of a person's workout routine.

The goal of "exercise when injured" is not a suggested goal to set for yourself because exercising when injured can worsen the injury and delay the healing process. It is important to prioritize rest and recovery when injured in order to allow the body to heal properly.

Cardiac muscles are a special type of striated muscle tissue that form the walls of the heart. Unlike smooth muscles, which are found in organs like the intestines and blood vessels, cardiac muscles are unique to the heart. They are responsible for the contraction and relaxation of the heart, allowing it to pump blood throughout the body. Skeletal muscles, on the other hand, are attached to bones and are responsible for voluntary movements. Therefore, the correct answer is cardiac muscles.

Psychological illnesses that cause people to undereat, overeat, or practice other dangerous nutrition-related behaviors are known as eating disorders. Eating disorders are characterized by abnormal eating habits and severe distress or concern about body weight or shape. These disorders can have serious physical and psychological consequences and require professional treatment.

Water walking is done primarily by people who are injured or in rehabilitation because it provides a low-impact workout that is gentle on the joints. The buoyancy of the water reduces the stress on the body, making it an ideal exercise for those recovering from injuries or with limited mobility. Water walking allows individuals to strengthen their muscles, improve cardiovascular fitness, and increase range of motion without putting excessive strain on their bodies. It is a safe and effective form of exercise for individuals looking to regain strength and mobility after an injury.

Exercise is defined as physical activity that is planned, structured, and repetitive, with the goal of improving fitness. This definition highlights the importance of having a specific plan and structure in place for physical activity, as well as the repetitive nature of exercise. By engaging in regular exercise, individuals can expect to see improvements in their overall fitness levels, including cardiovascular endurance, muscular strength, and flexibility. This definition also implies that exercise is intentional and purposeful, rather than simply any movement or daily task.

Skeletal muscles are voluntary muscles, meaning that they are under conscious control. This allows individuals to intentionally move and control their skeletal muscles to perform various movements and actions. Unlike involuntary muscles, such as the muscles in the digestive system, skeletal muscles require conscious effort and input from the brain to function.

Flexibility refers to a joint's ability to move through its full range of motion. It is the measure of the muscles and connective tissues' ability to stretch and lengthen, allowing for a wide range of movement. Flexibility is important for maintaining good posture, preventing injuries, and improving overall physical performance. It can be improved through regular stretching and exercises that target specific muscles and joints.

Maintaining a healthy weight is important for heart and lung health as excess weight can put strain on these organs. Eating right, which includes consuming a balanced diet with fruits, vegetables, and whole grains, provides essential nutrients for the heart and lungs. Avoiding tobacco is crucial as smoking damages the lungs and increases the risk of heart disease. Therefore, all of these factors contribute to keeping the heart and lungs healthy.

Teens should be exercising more than 120 minutes each week because regular physical activity is essential for their overall health and well-being. Engaging in physical exercise helps teens maintain a healthy weight, build strong muscles and bones, improve cardiovascular fitness, and enhance their mental health. Additionally, regular exercise can reduce the risk of developing chronic diseases later in life, such as obesity, heart disease, and type 2 diabetes. Therefore, it is important for teens to prioritize regular physical activity and aim for at least 120 minutes of exercise each week.

A commitment refers to a pledge or a promise made by an individual. It involves dedicating oneself to a particular course of action or obligation, demonstrating a strong sense of responsibility and determination to follow through with the commitment. This can be seen in various aspects of life, such as personal relationships, work, or goals. By choosing this answer, it indicates an understanding of the concept of commitment as a voluntary agreement or assurance to fulfill a specific task or obligation.

The human body is composed of approximately 60-70% water. Water is essential for various bodily functions such as digestion, circulation, temperature regulation, and waste removal. It is found in cells, blood, and other bodily fluids, and plays a crucial role in maintaining overall health and well-being. Therefore, the statement "Your body is made up of 60-70% water" is true.

Regular physical activity, especially weight-bearing exercises, stimulates bone growth and strengthens bones. When people engage in regular physical activity, their bones experience increased stress and strain, leading to the deposition of more minerals and increased bone mass. Inactive individuals, on the other hand, do not subject their bones to the same level of stress and strain, resulting in lower bone mass. Therefore, it is true that active people generally have more bone mass than inactive people.

Family normally has the greatest influence on someone's eating habits. This is because the family plays a significant role in shaping a person's eating habits from an early age. They are responsible for providing meals and creating a food environment at home. Family members often share meals together and influence each other's food choices and preferences. Additionally, family traditions, cultural practices, and the availability of certain types of food at home can also impact someone's eating habits.

Olympic-style lifts implement many multi-joint movements. These exercises, such as the clean and jerk and the snatch, involve multiple muscle groups and joints working together to perform the movements. Unlike biceps curls or triceps extensions, which primarily target only one muscle group and joint, Olympic-style lifts engage the entire body, including the legs, back, shoulders, and arms. Quadriceps extensions also focus on a single muscle group and joint, whereas Olympic-style lifts provide a more comprehensive workout by involving multiple joints and muscle groups simultaneously.

A short bar with weights on both ends, designed to be held and lifted with one hand is called a barbell. Barbells are commonly used in weightlifting and strength training exercises to build muscle and increase strength. They provide a versatile and effective way to perform compound exercises such as squats, deadlifts, and bench presses. Unlike weight machines that have a fixed range of motion, barbells allow for a more natural and functional movement pattern, engaging multiple muscle groups and promoting overall stability and coordination. Using a barbell allows for progressive overload, as the weight can be easily adjusted by adding or removing plates.

Long term goals in resistance training include toning selected muscles and developing leaner body mass. This means that the individual aims to not only strengthen and define specific muscles but also reduce overall body fat and increase muscle definition. By combining these two goals, the individual can achieve a more toned and sculpted physique. Increasing fluid intake and developing leaner body mass are not specifically mentioned as long term goals in resistance training.

Exercising is not inherently dangerous and should not be avoided at all costs. In fact, regular exercise is generally considered beneficial for overall health and well-being. While there can be risks associated with certain types of exercise or if done improperly, with proper guidance and precautions, exercise can be safe and even essential for maintaining a healthy lifestyle. Therefore, the statement that exercising should be avoided at all costs is false.

Intensity refers to the difficulty or exertion level of your physical activity or exercise. It is a measure of how hard your body is working during the activity. The intensity can vary depending on factors such as heart rate, breathing rate, and sweat production. Higher intensity activities require more effort and energy expenditure, while lower intensity activities are less demanding. Monitoring intensity is important as it helps determine the effectiveness of your workout and helps you set appropriate goals for your fitness level.

The wall sit is the exercise that evaluates muscular endurance. It involves sitting against a wall with your knees bent at a 90-degree angle and holding that position for as long as possible. This exercise primarily targets the muscles in the lower body, particularly the quadriceps, hamstrings, and glutes. It requires strength and endurance in these muscles to maintain the position for an extended period of time. The finger pinch test, zipper stretch, and jumping jacks do not specifically assess muscular endurance.

Free weights, such as dumbbells and barbells, allow for a wider range of exercises and movements compared to weight machines. This versatility allows for more variety in workout routines and targeting specific muscle groups. Additionally, free weights are generally less expensive than weight machines, making them a more cost-effective option for individuals who want to incorporate strength training into their fitness routine. Therefore, the statement that free weights offer the advantage of being more versatile and less expensive than weight machines is true.

Increasing your fluid intake for a week is considered a short term goal because it is a specific and achievable objective that can be accomplished within a relatively short period of time. Unlike long term goals which require sustained effort and commitment over an extended period, short term goals are typically focused on immediate actions and results. In this case, increasing fluid intake for a week can be easily tracked and accomplished within a specific timeframe, making it a short term goal.

Calcium is an essential nutrient that plays a crucial role in building and maintaining strong bones. It is needed for the development of healthy bones and teeth, and also helps in maintaining their strength and density. Calcium is particularly important during childhood and adolescence when bones are growing rapidly, and also for older adults who are at risk of osteoporosis. Additionally, calcium aids in other vital body processes such as muscle contractions and the transmission of nerve impulses that control muscle movement. Therefore, the correct answer is that calcium helps build and maintain strong bones.

The three steps or behaviors to avoid risk factors are being physically active, maintaining a healthy eating habit, and avoiding smoking. Engaging in regular physical activity helps in maintaining overall health and reducing the risk of various diseases. Following a healthy eating pattern ensures proper nutrition and reduces the risk of developing chronic conditions. Avoiding smoking is crucial as it is a major risk factor for numerous health problems, including cancer, heart disease, and respiratory issues. Therefore, all of the mentioned steps contribute to avoiding risk factors and promoting a healthier lifestyle.

Showing off is not a suggestion for safety because it involves performing risky or dangerous actions solely for the purpose of impressing others. Safety guidelines prioritize minimizing risks and preventing accidents, so engaging in behaviors that prioritize showing off rather than safety can increase the likelihood of injuries or accidents. Therefore, it is important to avoid showing off and instead focus on following safety measures and guidelines.

The given answer "All of the above" is correct because it includes all the mentioned options that can help prevent injury while exercising. Using proper safety equipment ensures protection and reduces the risk of accidents. Wearing reflective clothing at night enhances visibility, reducing the chances of collisions or accidents. Seeking medical attention when necessary helps in identifying and addressing any potential health issues or injuries. Avoiding the use of anabolic steroids is important as they can have detrimental effects on the body, including increased risk of injury. Therefore, following all these measures collectively can contribute to preventing injuries during exercise.

Minerals are substances that the body cannot manufacture but that are needed for forming healthy bones and teeth and for regulating many vital body processes. They play a crucial role in maintaining overall health and are essential for various bodily functions. Without an adequate supply of minerals, the body may experience deficiencies and imbalances, leading to various health issues. Therefore, it is important to consume a balanced diet that includes a variety of mineral-rich foods to ensure the body's mineral needs are met.

In resistance training, setbacks are common and expected. This is because the body needs time to adapt and build strength. Setbacks can occur due to various reasons such as muscle soreness, fatigue, or lack of progress. Being prepared for setbacks means understanding that they are a normal part of the training process and not getting discouraged by them. It also involves having a mindset to overcome setbacks, adjusting training plans if necessary, and staying consistent and committed to the training program.

Diabetes is not a treatment for obesity, but rather a medical condition that can be caused by obesity. Obesity is typically treated through a combination of exercise, diet, and behavior modification. Diabetes management may be a part of the overall treatment plan for someone who is both obese and diabetic, but it is not a standalone treatment for obesity.

Exercise should not only be done by young people who have extra energy. Exercise is beneficial for individuals of all ages, regardless of their energy levels. Regular physical activity has numerous health benefits, including improving cardiovascular health, maintaining a healthy weight, and reducing the risk of chronic diseases. It is important for people of all ages to engage in exercise to maintain overall physical and mental well-being. Therefore, the statement that exercise should only be done by young people who have extra energy is false.

When starting out, it is recommended to start stretching three days a week. This allows the body to gradually adapt to the new routine and prevents overexertion or injury. Starting with a lower frequency also allows for proper rest and recovery between stretching sessions. As flexibility improves and the body becomes more accustomed to stretching, the frequency can be gradually increased.

Smooth and cardiac muscles are both types of involuntary muscles. Smooth muscles are found in the walls of organs and blood vessels, while cardiac muscles make up the heart. Unlike skeletal muscles, which are under voluntary control, smooth and cardiac muscles work automatically without conscious effort. This is why the statement is true.

Good nutrition comes from variety, moderation, and balance. This means that to have a healthy diet, it is important to consume a variety of different foods from different food groups. Moderation refers to eating appropriate portions and not overindulging in any particular food. Balance refers to ensuring that the diet includes a combination of macronutrients (carbohydrates, proteins, and fats) as well as micronutrients (vitamins and minerals) in the right proportions. By following these principles, individuals can obtain the necessary nutrients for optimal health and wellbeing.

FITT stands for frequency, intensity, time, and type. This acronym is commonly used in exercise and fitness to outline the key components of a well-rounded workout program. Frequency refers to how often a person exercises, intensity refers to the level of difficulty or effort exerted during exercise, time refers to the duration of each exercise session, and type refers to the specific activities or exercises chosen. By considering these four factors, individuals can design a fitness routine that meets their goals and promotes overall health and well-being.

Some joints in the body, such as the shoulder and hip joints, are classified as ball-and-socket joints, which allow for a wide range of motion (ROM) in multiple directions. On the other hand, hinge joints, like the knee and elbow joints, primarily allow movement in a forward and backward direction. Therefore, the statement that some joints allow a wide ROM while others are only designed to move forward and backward is true.

Adults who have high levels of cardio-respiratory endurance tend to have 70-80% slow twitch fibers. This means that individuals with high levels of cardio-respiratory endurance have a higher proportion of slow twitch muscle fibers in their muscles. Slow twitch fibers are responsible for endurance activities and are better suited for long-duration exercises such as running or cycling. Therefore, it is true that adults with high levels of cardio-respiratory endurance tend to have a higher percentage of slow twitch fibers.

The correct answer is sedentary activity. This is because talking on the phone does not require much physical movement or exertion. It is a stationary activity that can be done while sitting or lying down. It does not elevate heart rate or require significant energy expenditure, making it a sedentary activity.

Bananas are a great source of potassium. They are known to be one of the best natural sources of this essential mineral. Potassium is important for maintaining proper heart and muscle function, as well as regulating blood pressure. Bananas are also rich in other nutrients like vitamin C, vitamin B6, and dietary fiber, making them a healthy and nutritious choice.

Smooth muscles are muscles responsible for the movements of the internal organs, such as intestines, the bronchi of the lung, and the bladder. These muscles are involuntary and not under conscious control. They contract and relax to facilitate the movement and function of various organs within the body.

Fiber is known to help reduce the risk of cancer. This is because fiber helps to keep the digestive system healthy and functioning properly. It aids in preventing constipation and promotes regular bowel movements, which can help to remove toxins and waste from the body. Additionally, fiber can help to lower levels of estrogen in the body, which is beneficial in reducing the risk of certain types of cancer such as breast and ovarian cancer. Overall, a high-fiber diet is recommended as part of a healthy lifestyle to help reduce the risk of developing cancer.

Muscular strength refers to the maximum amount of force that a muscle or muscle group can generate against an opposing force. It represents the overall power and ability of the muscles to exert force. This measure is independent of factors such as body weight or size, making it an absolute measure of strength. Relative muscular strength, on the other hand, takes into account body weight or size, providing a ratio of strength to body mass. Resistance training is a form of exercise that aims to increase muscular strength through the use of resistance or weights.

Walking your dog is considered moderate-intensity exercise because it requires a moderate amount of effort and increases your heart rate. It is not sedentary, as it involves physical activity, nor is it anaerobic, as it does not involve intense bursts of activity. While walking your dog may not be as intense as aerobic exercise, it still provides health benefits and can contribute to overall fitness.
