Movement Analysis (Extended For Ib Grade 12)

This section addresses the principles of biomechanics, joint movements, muscle contractions, and the role of technology in analyzing human movement.

Introduction

This section introduces the significance of understanding human movement in IB Grade 12 Physical and Health Education, emphasizing movement analysis.

Section 1: Biomechanics

What Is Biomechanics?

Biomechanics studies mechanical principles related to human movement, focusing on forces acting on the body to improve athletic performance and prevent injury.

Levers In The Human Body

Levers in the human body are mechanical systems involving bones, joints, and muscles that facilitate movement.

Motion And Force

This section covers the various types of motions and forces acting on the human body, essential for understanding human movement in sports and physical activities.

Newton's Laws Of Motion

This section introduces Newton's three laws of motion and their applications in various physical contexts.

Section 2: Joint Types And Movements

Types Of Joints

This section covers the classification of joints based on their structure and movement capabilities, highlighting the different types of joints found in the human body.

Types Of Synovial Joints

This section covers the various types of synovial joints and their characteristics, exploring how they facilitate movement in the human body.

Range Of Motion (Rom)

Range of Motion (ROM) refers to the distance and direction a joint can move, influenced by several factors.

Movement Terminology

This section explores the fundamental terminology used to describe human movement, including key actions like flexion and extension.

Section 3: Motor Units And Muscle Contraction

Motor Unit Structure

This section explains the structure of motor units, including their components and the relationship between motor unit size and movement control.

Neuromuscular Junction

The neuromuscular junction is the critical site where motor neurons communicate with muscle fibers to trigger muscle contractions.

Muscle Contraction Types

This section describes the different types of muscle contractions, including isometric, isotonic (concentric and eccentric), and isokinetic contractions.

Motor Unit Recruitment

Motor unit recruitment is the process of activating more motor units and increasing their firing frequency to regulate muscle force during contraction.

Section 4: Video Analysis In Sports
