About This Chapter
Promoting Healthy Lifestyles: Exercise & Your Body - Chapter Summary
Use the lessons in this chapter to examine how skeletal muscles work together to enable movement, provide support and help maintain homeostasis. Instructors provide you with an overview of muscle anatomy by discussing skeletal muscles' origin and insertion points, isometric and isotonic contraction types and the roles of muscle agonists, antagonists and synergists.
Additional topics of study cover the processes involved in converting the food we eat into the energy our muscles need to function. You can also find out why regular exercise helps us manage stress, improves our mental health and prolongs our life span. Finally, explore the different components of exercise regimens useful for improving cardiovascular endurance, flexibility or strength. Listed below are just some of the topics covered in this chapter:
- Muscular anatomy and function
- Muscle metabolism and ATP synthesis
- Benefits of regular physical activity
- Types of exercise programs
- Components of personal hygiene
This chapter on exercise delivers instruction in the form of short, illustrated video lessons. You can watch them as many times as you need or switch things up and access content via their corresponding transcripts. Both formats allow you to jump ahead or go back to the topics you want to study. The self-assessment quizzes also link back to these materials to help reinforce your understanding of each lesson's main points.
1. What Is the Muscular System? - Function & How Muscles Work in Groups
Ever feel overwhelmed when you look at all those muscles in your textbooks? Well, if you do, then maybe learning a little about their anatomy and organization and how they work together will help you sort through it all. In this lesson, learn about the muscle itself and how it works with others to help the muscular system function.
2. How Muscle Levers Affect Muscle Efficiency
Muscular contraction creates force to move the weight of our body and body parts. This lesson describes the three lever systems utilized by our body to create movement. The efficiency of each lever type in terms of strength, speed and distance are identified along with examples.
3. Muscle Metabolism: Synthesis of ATP
Did you know our muscles use billions of molecules every second to contract? This lesson describes the different metabolic processes by which ATP is generated by the muscle cell. Examples are utilized to define glycolysis, the citric acid cycle and oxidative phosphorylation.
4. Major Skeletal Muscle Functions
Did you know that skeletal muscle does more than just move our body parts? This lesson describes how skeletal muscles are used for movement, posture, swallowing, defecation, urination and homeostasis.
5. 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.
6. 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.
7. Isometric and Isotonic Contraction: Definition and Examples
Did you know that muscles can contract and not move your limbs? This lesson describes the nature of both isometric and isotonic skeletal muscle contraction. Examples are utilized to help you understand how this works.
8. What Is Aerobic Exercise? - Definition, Benefits & Examples
In this lesson, you'll learn about the characteristics of aerobic exercise and its many health benefits. You will also read about examples of different types of aerobic workouts.
