About This Chapter
Muscular Strength & Flexibility in Fitness - Chapter Summary
In this chapter's brief lessons you will take a look at how muscle efficiency is affected by muscle levers, the functions of major skeletal muscle, and the meaning and types of articulation caused by muscular contraction.
Here you will examine definition, examples and benefits or anaerobic exercise and consider how to design a program that will promote both flexibility and strength. Other topics covered in this chapter include:
- Skeletal, smooth and cardiac muscle tissue types
- Definition and examples of isotonic and isometric contraction
- Synthesis of ATP in muscle metabolism
- Stretches and exercises for flexibility in fitness
- Principles and skills for developing flexibility
- Weight-shift training for improving control and balance
- Strategies used to help develop proper posture
Log in from any Internet-ready mobile device to work on these studies. You can review the lessons and take the accompanying quizzes as often as necessary, and track your progress on your dashboard.
1. Types of Muscle Tissue: Skeletal, Cardiac & Smooth
Have you ever wondered why muscle has different names such as striated, smooth, voluntary, or involuntary? This lesson describes the different types of muscle tissue based on their histology, mechanism of contraction, and regulation.
2. 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.
3. 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.
4. 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.
5. 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.
6. How Muscular Contraction Causes Articulation: Definition & Types
Skeletal muscle contraction causes all types of movement. Movement at our joints is referred to as articulation. All articulation is described in reference to the anatomical position, and most articulations are identified in opposite pairs. This lesson identifies and describes the major articulations of the human body.
7. Anaerobic Exercise: Definition, Benefits & Examples
In this lesson, you will learn about anaerobic exercise and its health benefits. In addition, you will obtain knowledge of the various types of anaerobic workouts.
8. Flexibility in Fitness: Definition, Stretches & Exercises
Flexibility is important in fitness because it allows for better performance when playing sports or exercising, and during your day-to-day activities, it makes bending, walking, and lifting easier. In this lesson, you will learn how stretching and certain types of exercises can help improve flexibility.
9. Developing Flexibility: Principles & Skills
In this lesson, we will tackle two questions: Why do I need flexibility? How do I gain flexibility? Stretching and flexibility help us stay limber, remain injury free, improve performance, and generally achieve better health and wellness.
10. Improving Control & Balance with Weight-Shift Training
Weight-shifting training is used to help an individual regain the ability to maintain balance after an injury or disease. In this lesson, the student will learn the key elements of balance is and how weight-shift training is used to improve balance.
11. Strategies for Developing Correct Posture
In this lesson we will discuss the components of developing correct posture. We will explore the different ways to improve posture and how correct posture can lead to a healthier lifestyle.
12. Designing a Program to Promote Strength & Flexibility
In this lesson, we will review workout routines to promote strength and flexibility. We will also discuss some of the current methods utilized to achieve strength and flexibility along with crucial dietary habits and safety practices.
