I can’t believe next week is the last week of classes for me! My final exam is next Monday! Ahhh! I feel like I learned a lot in my first nutrition class, but some of it was already knowledge to me. 🙂 We didn’t really talk too in-depth about the chapter on Nutrition & Fitness (I wish we had!) but here is what I learned on the little bit we did discuss in class.
There is a difference between physical fitness and physical activity. Physical fitness is considered good health and physical condition and is the result of exercise and proper nutrition. Physical activity refers to body movement that results in expending calories.
Fitness has five basic components:
1. Cardiorespiratory endurance – this is the body’s ability to sustain prolonged exercise
2. Muscle endurance – this is the ability of the muscle to produce prolonged effort
3. Muscle strength – the greatest amount of force exerted by the muscle at one time
4. Flexibility – the joint’s ability to move freely though a full and normal range of motion
5. Body composition – the relative proportion of muscle, fat, water and other tissues in the body
In order to lose weight, you must exercise. To achieve your weight goal, you should exercise at least 60 – 90 minutes a day! Also, you should find activities that you enjoy doing and do them on a regular basis.
Carbohydrates are the primary source of energy during high-intensity exercise.
Fats are the primary source of energy during low-to-moderate intensity exercise.
Generally, you should have between 40-80 grams of protein a day.
