1. What is Physical Fitness? - Definition & Importance
Physical fitness is your ability to carry out tasks without undue fatigue. Learn about the components of physical fitness: cardiorespiratory endurance, muscle strength, muscle endurance, flexibility and body composition and why they are important.
2. The Benefits of Regular Physical Activity: Mental Health, Stress & Life Span
The mind and body can greatly benefit from even 30 minutes of exercise a day. Find out exactly what impact regular exercise can have on your mind, body, and lifespan in this video lesson.
3. Components of Exercise Programs: Aerobics, Strength Training & Stretching
Ever wonder what stretching, strength training, and aerobic exercises are? You'll learn about them in this lesson. You'll also find out what some basic recommendations are for each type of exercise.
4. Physical Activity: Health, Fitness and Performance
Physical activity is any movement of your muscles that uses energy. Physical activity helps you achieve better health, fitness and performance. Learn how the overload principle and specificity principle improve your fitness and performance.
5. How Energy-Containing Molecules Support Physical Activity
Physical activity requires energy. Adenosine triphosphate (ATP) is the form of energy your body likes to use. In order to keep enjoying your physical activity, your body must continually make ATP. Learn how this is done both with and without oxygen.
6. Preventing & Treating Fitness Injuries
Injuries are a risk whenever you start a fitness program. Learn about ways to prevent common injuries, such as sprains and strains, as well as how to treat them using the RICE method, which stands for rest, ice, compress and elevate, in this lesson.
7. Nutrients and Calorie Needs in an Athlete's Training Diet
Whether you are a casual athlete or a competitive endurance athlete, your body needs the right amount and mix of nutrients to maximize performance. Learn about an athlete's calorie needs and overall nutrient requirements during training in this lesson.
8. Foods to Optimize Athletic Performance Before, During & After Competition
Competitive athletes rely on good nutrition to give them an edge over their competition. Learn about carbohydrate loading as well as foods athletes use before, during and after competitions to enhance performance and endurance.
9. Nutrients to Support Physical Activity
It is important to stay well-nourished with carbohydrates, protein, fats and various vitamins and minerals during physical activity. Learn about these nutrients that support physical activity as well as the benefits of water during active times.
10. Staying Well Hydrated: The Importance of Fluids During Exercise
Staying well-hydrated during exercise will help prevent dehydration, as well as the heat-related illnesses: heat cramps, heat exhaustion and heat stroke. Learn how to hydrate with the right fluid and sodium balance to avoid hyponatremia in this lesson.
11. Supplements & Ergogenic Aids: Effects on Performance
Many supplements and ergogenic aids are marketed to enhance athletic performance. Some are beneficial, but others provide little benefit and may be a health risk. Learn about chromium picolinate, anabolic steroids, creatine, caffeine and carnitine in this lesson.
