Ch 11: Muscular Strength & Flexibility in Fitness

About This Chapter

Use the video and text lessons in this chapter to learn about ways to develop strength and flexibility in muscles. You will get to know muscle tissue types, isotonic and isometric contractions, muscle levers, and programs for developing good posture.

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.

Types of Muscle Tissue: Skeletal, Cardiac & Smooth

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.

Major Skeletal Muscle Functions

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.

Isometric and Isotonic Contraction: Definition and Examples

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.

Muscle Metabolism: Synthesis of ATP

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.

How Muscle Levers Affect Muscle Efficiency

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.

How Muscular Contraction Causes Articulation: Definition & Types

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.

Anaerobic Exercise: Definition, Benefits & Examples

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.

Flexibility in Fitness: Definition, Stretches & Exercises

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.

Developing Flexibility: Principles & Skills

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.

Improving Control & Balance with Weight-Shift Training

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.

Strategies for Developing Correct Posture

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.

Designing a Program to Promote Strength & Flexibility

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.
