Physical Activity & Fitness Quizlet Notes
Physical Activity & Fitness Quizlet – Multiple Choice Study Set
Q1: What is the definition of physical activity?
A1: Movement carried out by the skeletal muscles that requires energy ✅Explanation: This definition distinguishes physical activity from other actions that may not involve skeletal muscle movement, emphasizing the energy expenditure involved in physical activity.
Q2: What characterizes healthy body composition?
A2: High proportion of muscle, bone, and water and an acceptably low proportion of fat ✅Explanation: Healthy body composition reflects an ideal ratio of muscle to fat, supporting overall health and fitness.
Q3: What does the Physical Activity Readiness Questionnaire (PAR-Q) achieve?
A3: Determine exercise safety ✅Explanation: The PAR-Q is designed to identify pre-existing health conditions that may affect exercise safety, allowing individuals to exercise more confidently.
Q4: What is the definition of muscular strength?
A4: The amount of force a muscle can produce with a single maximum effort ✅Explanation: Muscular strength refers to the capability of a muscle to exert maximum force, which can be assessed using techniques like the one-repetition maximum (1 RM) test.
Q5: What does the latest Physical Activity Guidelines for Americans recommend?
A5: Getting 150 minutes of moderate-intensity aerobic exercise per week and performing resistance training at least two days per week ✅Explanation: These guidelines are set to encourage physical activity for health benefits, including both aerobic and strength training exercises.
Q6: "Exercise" and "physical activity" are synonyms.
A6: False ✅Explanation: While related, exercise is a subset of physical activity that is planned, structured, and repetitive, aimed at improving or maintaining physical fitness.
Q7: Leisure-time physical activity levels increased slightly in recent years.
A7: True ✅Explanation: This reflects a trend towards higher engagement in physical activities during leisure time across various populations.
Q8: Which change to muscle cells causes older adults to lose muscular strength?
A8: The cells get smaller in size ✅Explanation: Muscle atrophy typically occurs in older adults, leading to reduced muscle mass and strength.
Q9: The principle of specificity states that placing increasing amounts of stress on the body causes adaptations that improve fitness.
A9: False ✅Explanation: While specificity refers to training targeting specific muscle groups, the statement describes the overload principle rather than the principle of specificity itself.
Q10: A person with excessive body fat is less likely to experience health problems.
A10: False ✅Explanation: High levels of body fat are associated with increased risks of various health issues, including cardiovascular diseases and diabetes.
Q11: Swimming and jogging can develop cardiorespiratory endurance.
A11: True ✅Explanation: These activities are both aerobic exercises that enhance the body's ability to use oxygen efficiently during prolonged activity.
Q12: Coordination is considered a health-related component of fitness.
A12: False ✅Explanation: While coordination is important for performance, it is classified as a skill-related component of fitness, rather than health-related.
Q13: What is the maximal improvement in the body's ability to transport and use oxygen that people can expect because of training?
A13: 5 to 30% ✅Explanation: Training significantly enhances aerobic capacity, but improvements can vary widely based on initial fitness levels and training regimens.
Q14: What determines the amount of overload needed to maintain or improve one's fitness level?
A14: Specificity ✅Explanation: Specificity in exercise programs ensures that overload is applied to the specific fitness components being targeted for improvement.
Q15: The benefits of exercise extend beyond disease prevention.
A15: True ✅Explanation: Exercise contributes to multiple aspects of wellness, including mental health, mood enhancement, and overall quality of life.
Q16: What is the best way to lose body fat?
A16: Sensible diet and regular exercise ✅Explanation: This approach promotes sustainable weight loss and maintains overall health, unlike crash diets or reliance on pills.
Q17: Which activities best develop muscular strength and endurance?
A17: Activities that involve working with resistance such as weights or performing calisthenic exercises ✅Explanation: These activities explicitly focus on enhancing muscle performance through resistance training.
Q18: Cardiorespiratory endurance is the ability to perform short duration, high intensity exercise.
A18: False ✅Explanation: Cardiorespiratory endurance refers to sustained activity over a longer duration at moderate intensity levels, not short bursts of effort.
Q19: The bottom level of the physical activity pyramid contains strength training and flexibility exercises.
A19: False ✅Explanation: The base of the pyramid is reserved for moderate-intensity exercise, while strength training and flexibility are positioned higher to complement the foundation.
Q20: Calisthenic exercises such as sit-ups and push-ups can develop muscular strength and endurance.
A20: True ✅Explanation: These exercises effectively promote both muscular strength and endurance through bodyweight resistance.
Q21: What is another name for cycle training?
A21: Periodization ✅Explanation: Periodization involves varying the training program's intensity and volume over time, often employed in cycling training regimens.
Q22: What is a key to improving fitness?
A22: Exercise consistently ✅Explanation: Regularity in exercise plays a crucial role in enhancing overall fitness levels.
Q23: Which activity best demonstrates specificity of training?
A23: Doing push-ups to develop chest and shoulder endurance ✅Explanation: Specificity indicates targeting particular muscles or fitness components related to the activity being performed.
Q24: Daily physical activity of 30 minutes per day is sufficient for most people to maintain weight loss.
A24: False ✅Explanation: Maintaining weight loss often requires more than 30 minutes of moderate activity for effective energy balance.
Q25: A warm-up reduces the temperature of muscles.
A25: False ✅Explanation: The purpose of a warm-up is to increase muscle temperature and prepare the body for exercise, mitigating the risk of injury.
