Answer: b) 150 minutes. According to the World Health Organization (WHO), adults should aim for at least 150 minutes of moderate-intensity aerobic activity per week for health benefits. Exercising for 30 minutes, 300 minutes, or 500 minutes is either insufficient or excessive.

What is the recommended amount of exercise for adults per week?

Answer: b) Protein. Protein is crucial for muscle repair and growth, making it an essential nutrient for individuals engaging in physical activity. Carbohydrates, fats, and vitamins play other important roles in the body but are not primarily responsible for muscle repair.

Which nutrient is essential for building and repairing muscles?

Answer: b) Improve flexibility and prevent injury. Stretching before exercise helps to loosen muscles and increase flexibility, reducing the risk of injury during physical activity. Increasing heart rate, building muscle strength, and reducing blood pressure are not the primary goals of pre-exercise stretching.

What is the primary purpose of stretching before exercise?

Answer: b) Swimming. Aerobic exercises, also known as cardiovascular exercises, involve continuous movement of large muscle groups and increase the heart rate. Swimming is an excellent example of aerobic exercise. Weightlifting, sprinting, and yoga primarily focus on strength, speed, and flexibility, respectively.

Which activity is considered a form of aerobic exercise?

Answer: b) Improved cognitive function and mood. Sufficient sleep is essential for brain health, supporting cognitive function, mood regulation, and overall well-being. Increased stress levels, reduced hydration, and enhanced muscle recovery are not the primary benefits of sleep.

What is the main benefit of getting enough sleep?

Answer: b) Unsaturated fat. Unsaturated fats, such as those found in nuts, seeds, and avocados, are considered healthy fats that support heart health and overall wellness. Saturated fat, trans fat, and cholesterol, when consumed in excess, can have negative effects on health.

Which type of fat is considered healthy and important for the body?

Answer: b) Drinking water. Water is the best choice for staying hydrated during exercise, as it helps regulate body temperature and replace fluids lost through sweat. Sugary beverages, energy drinks, and avoiding fluids can lead to dehydration and hinder performance.

What is the best way to stay hydrated during exercise?

Planks. Planks are an effective exercise for strengthening the core muscles, including the abdominal muscles, lower back, and hips. Bicep curls, leg press, and calf raises primarily target other muscle groups.

Which exercise helps strengthen the core muscles?

Reduces stress and improves mood. Regular exercise releases endorphins, which are chemicals in the brain that help reduce stress and improve mood. Exercise is associated with a lower risk of depression, reduced anxiety, and improved cognitive function.

How does regular exercise benefit mental health?

5 servings. The recommended daily intake of fruits and vegetables is at least 5 servings per day, as they are rich in vitamins, minerals, and antioxidants essential for overall health. Consuming only 1, 3, or 10 servings may not provide adequate nutrients.

What is the recommended daily intake of fruits and vegetables?

ogging. Jogging is a form of aerobic exercise that helps improve cardiovascular health by increasing heart rate and strengthening the heart and lungs. While yoga, weightlifting, and Pilates offer other health benefits, they do not primarily target cardiovascular health.

Which exercise is beneficial for improving cardiovascular health?

 Protecting the body against infection and illness. The immune system is responsible for defending the body against harmful pathogens, such as bacteria, viruses, and parasites. Regulating body temperature, digesting food, and transporting oxygen are functions of other body systems.

Protecting the body against infection and illness

What is the main function of the immune system?

2-3 times a week. Strength training workouts should be performed 2-3 times a week to allow for adequate muscle recovery and growth. Exercising once a week, daily, or every other week may not provide optimal results.

What is the recommended frequency for strength training workouts?

Carbohydrates. Carbohydrates are the body's primary source of energy, providing fuel for physical activity and brain function. While protein, fat, and fiber are important for overall health, they are not the primary sources of energy.

Which nutrient is the body's primary source of energy?

Heart rate. Monitoring heart rate during exercise is an effective way to gauge intensity and ensure that individuals are working at an appropriate level for their fitness goals and abilities. Duration, distance, and weight lifted may provide information about the exercise performed but do not directly measure intensity.
