Following Is One Very Simplistic And Partial Example Of How To Complet

Following is an example of a movement analysis project completion. The example provided is very simplistic and partial, intended to illustrate the format and approach. It lacks extensive narrative details and includes images or illustrations. This example is not fully complete and should not be used as a template for submission, as your actual assignment will require more comprehensive analysis and explanation. The analysis involves identifying joint actions, muscle involvement (agonists and antagonists), and providing rationales for movement classifications across different body parts and positions.

The project entails analyzing a series of three images or positions, each depicting various body parts in different movements. For each position, students are expected to record specific information: the body orientation, movement classification, joint actions or positions, corresponding muscles acting as agonists and antagonists, and provide reasoned explanations for their choices. Attention to detail, clarity, professionalism, and proper formatting are essential; all data should be aligned across columns for easy readability.

Potential issues such as misalignment, incomplete data, or failure to follow formatting instructions can result in penalties. The assignment emphasizes thoroughness across all body parts, clear justification of classification choices, and neat, professional presentation. Students are encouraged to consult with instructors if clarification is needed and should avoid last-minute submissions. The instructions underscore the importance of including all relevant details and maintaining consistency across analyses of both right and left sides when in the same position.

Introduction

Movement analysis is a foundational task in kinesiology and biomechanics, serving to understand the mechanics and muscle functions involved in human movement. Correctly identifying joint actions, muscle roles, and movement classifications allows practitioners and students to deepen their understanding of muscular coordination and biomechanical principles. This paper provides a comprehensive example of such an analysis based on three hypothetical body positions, illustrating the detailed process of recording and rationalizing movement data.

Overall Body Orientation and Movement Classification

In the analyzed positions, the subject’s orientation was predominantly standing, with some positions indicated as seated or lying prone or supine. The movement classifications for each position varied, with tasks being manipulative, locomotor, or non-manipulative; gross or fine motor; and open or closed tasks. Justification was based on the observed body movements, context, and typical movement patterns, aligning with standard biomechanical definitions (Levangie & Norkin, 2011; Magnusson, 2001).

Position 1: Body in Standing, Reaching Forward

In the first position, the subject appears to be standing with the arms extended forward, indicative of a manipulated task requiring arm extension. The classification was identified as a manipulative, gross motor, and open task, consistent with activities like reaching or grabbing. The shoulder girdle was elevated and abducted, with the shoulder joint performing extension and abduction actions.

Joint Action and Muscles:

• Right Shoulder Girdle: Elevation and abduction involving the upper fibers of the trapezius and serratus anterior.
• Right Elbow and Forearm: Extension via the triceps brachii, with the antagonist muscles being the biceps brachii and brachialis, responsible for flexion.
• Wrist/Hand: Extension via extensor carpi radialis longus and brevis; antagonists involved flexor muscles (flexor carpi radialis and ulnaris).

Rationale included observing the arm’s position relative to the torso, the muscle actions involved in reaching, and the classification aligning with typical manipulative tasks in functional activities.

Position 2: Body in Sitting, Arm Flexion

The second position depicted a seated posture with the arm flexed at the elbow, typical of lifting or pulling tasks. Movement classification was similarly manipulative and gross motor but identified as a closed task, since the movement was within a predictable, constrained environment.

Joint Action and Muscles:

• Shoulder Girdle: Slight protraction with the pectoralis minor activating to stabilize scapula.
• Elbow / Forearm: Flexion mediated by the biceps brachii and brachialis, with antagonists such as triceps brachii.
• Wrist/Hand: Maintains neutral or slight extension, controlled by the wrist extensor muscles.

Explanation was based on the direction of movement, muscle roles during elbow flexion, and the closed system of the seated position facilitating this movement.

Position 3: Body in Lying Prone, Shoulder Extension

The third position involved the subject lying prone, with the arm elevated posteriorly, representing shoulder extension. This was classified as a manipulative, gross motor, and open task, typical of reaching behind or swimming motions.

Joint Action and Muscles:

• Shoulder Girdle: Depression and adduction, with the lower trapezius and latissimus dorsi primarily involved.
• Elbow/Forearm: Slight extension or stability, assisted by triceps brachii.
• Wrist/Hand: Neutral or slight extension, controlled by extensor muscles.

Justification for classification rested on the movement’s functional context, muscle activation patterns, and the open nature of the task facilitating multi-directional movement.

Conclusion

This analysis exemplifies a systematic approach to movement analysis, emphasizing careful observation, identification of muscle roles, and logical classification. Proper documentation and rationalization rooted in biomechanical principles are essential for comprehensive understanding. Accurate analysis supports effective training, rehabilitation, and research initiatives, underscoring the importance of precise movement assessment in kinesiology and biomechanics.
