The Three Parts of Physical Activity

Part 1: Aerobic Exercise

Aerobic exercise is a type of physical activity that increases the heart rate and breathing rate, and improves cardiovascular fitness. It is important to include aerobic exercise in a fitness routine because it has numerous health benefits, including weight management, improved cardiovascular health, and reduced risk of chronic diseases such as diabetes and heart disease.

Definition and Explanation

Aerobic exercise is any activity that raises the heart rate and breathing rate and involves the large muscle groups. It is also known as “cardio” and can include activities such as running, cycling, swimming, and dancing. Aerobic exercise increases the delivery of oxygen and nutrients to the muscles, which helps the muscles to function more efficiently and effectively.

Examples of Aerobic Exercise

There are many different types of aerobic exercises that can be performed, including:

  • Running or jogging
  • Cycling
  • Swimming
  • Dancing
  • Rowing
  • Aerobic classes such as Zumba or kickboxing
  • Hiking
  • Skiing
  • Skating

Recommended Frequency and Duration

The American Heart Association recommends that adults engage in at least 150 minutes of moderate-intensity aerobic exercise per week, or 75 minutes of vigorous-intensity aerobic exercise per week. Aerobic exercise should be performed for at least 10 minutes at a time, and preferably for longer periods of time to achieve the recommended amount of exercise per week. It is important to gradually increase the intensity and duration of aerobic exercise over time to avoid injury and to improve cardiovascular fitness.

Part 2: Strength Training

Definition and Explanation

Strength training is a form of physical activity that involves the use of resistance to increase muscle strength and size. This type of exercise can be achieved through a variety of methods, including weightlifting, resistance bands, and bodyweight exercises. The goal of strength training is to progressively overload the muscles, causing them to adapt and grow stronger over time.

Examples of Strength Training Exercises

There are many strength training exercises that can be performed, including:

  • Weightlifting: exercises such as squats, deadlifts, bench presses, and barbell rows can be performed using free weights or weight machines.
  • Resistance Bands: exercises such as bicep curls, tricep extensions, and shoulder presses can be performed using resistance bands.
  • Bodyweight Exercises: exercises such as push-ups, pull-ups, and planks can be performed using only your body weight for resistance.

Recommended Frequency and Duration

The recommended frequency and duration of strength training exercises may vary depending on your fitness level and goals. However, it is generally recommended to perform strength training exercises at least two to three times per week, with each session lasting between 30 to 60 minutes. It is important to gradually increase the intensity and difficulty of the exercises over time to continue making progress and avoid plateauing.

Part 3: Flexibility Exercises

Flexibility exercises are a crucial component of any physical activity routine. They help to improve the range of motion of the joints and muscles, reduce the risk of injury, and enhance overall physical performance. In this section, we will discuss the definition and explanation of flexibility exercises, provide examples of these exercises, and offer recommendations for frequency and duration.

Flexibility exercises are designed to improve the ability of the muscles and joints to move through their full range of motion. These exercises typically involve stretching the muscles and connective tissues to their limits, with the goal of increasing their length and elasticity. This increased flexibility can improve athletic performance, reduce the risk of injury, and enhance overall physical function.

Examples of Flexibility Exercises

There are many different types of flexibility exercises, each targeting different muscle groups and joints. Some examples of flexibility exercises include:

  • Hamstring stretches: These stretches target the back of the thigh muscles, which are often tight in individuals who sit for long periods of time. To perform a hamstring stretch, sit on the floor with your legs extended in front of you and reach forward to touch your toes.
  • Calf stretches: These stretches target the muscles in the lower leg, which can become tight due to high-impact activities like running. To perform a calf stretch, stand facing a wall and place one foot behind the other, with the heel of the back leg touching the wall. Lean forward into the stretch, keeping your weight on your front leg.
  • Shoulder stretches: These stretches target the muscles and tendons around the shoulder joint, which can become tight from repetitive movements like typing or carrying heavy bags. To perform a shoulder stretch, stand in a doorway with your arms extended out to the sides and rest your forearms on the doorway, allowing your shoulders to relax.

Flexibility exercises should be incorporated into your physical activity routine at least a few times per week, depending on your individual needs and goals. It is recommended to hold each stretch for at least 15-30 seconds, and to repeat each stretch several times. A typical flexibility training session might last anywhere from 5-15 minutes, depending on the number and variety of stretches performed. It is important to listen to your body and move at a pace that feels comfortable and safe, rather than pushing yourself too hard and risking injury.

How Much Physical Activity is Enough?

  • Recommended daily amounts

The Centers for Disease Control and Prevention (CDC) recommend that adults engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week. This recommendation is based on scientific evidence that supports the health benefits of regular physical activity. Additionally, the CDC recommends engaging in muscle-strengthening activities on two or more days per week.

  • Tips for incorporating physical activity into daily routine

Incorporating physical activity into a daily routine can be challenging, but there are several tips that can make it easier. One tip is to break up sedentary behavior, such as sitting for long periods of time, with short bursts of physical activity. This can be as simple as taking a short walk or doing a few minutes of stretching every hour. Another tip is to engage in physical activity that is enjoyable and fun, such as dancing or playing a sport. This can make it easier to stay motivated and committed to regular physical activity. Finally, it can be helpful to plan and schedule physical activity in advance, so that it becomes a part of the daily routine. This can include setting reminders or scheduling workouts with a friend or accountability partner.

Safety Considerations

Physical activity is essential for maintaining a healthy lifestyle, but it’s crucial to prioritize safety when engaging in any form of exercise. The following are some safety considerations to keep in mind when participating in physical activity:

  • Warm-up and cool-down exercises: Before starting any workout, it’s important to warm up the muscles to prevent injury.
