Movement Analysis

Movement Analysis

Introduction

  • Importance of movement quality

    • Crucial for enhancing athletic performance.

    • Directly linked to injury prevention.

  • Goals of movement analysis

    • Assessment of motor patterns during physical activity or sports.

    • Identification of inefficiencies and dysfunctions within movements.

  • Role of feedback in performance & injury prevention

    • Feedback aids in refining movement techniques and fostering corrective measures to avoid injuries.

What is Movement Analysis?

  • Definition: Movement analysis is the observation and evaluation of how the body moves during exercise or sport.

  • Main Functions:

    • Assess mechanics.

    • Identify dysfunctions in movement patterns.

    • Guide training decisions for athletes.

  • Types of Movement Analysis:

    • Qualitative: Focused on the quality and characteristics of movement.

    • Quantitative: Emphasizes numerical data and measurements about movement.

  • Tools Used in Movement Analysis:

    • Video Analysis: Capturing motion for further review.

    • Motion Capture: Recording and analyzing movement using technology.

    • Force Plates: Measuring the ground reaction forces exerted during movement.

    • Wearables: Devices that track performance metrics and feedback in real-time.

Key Components of Movement

  • Biomechanics:

    • Joint angles and their relationship to overall movement.

    • Force production during different exercises.

  • Kinematics:

    • Study of motion without considering the forces involved.

    • Key metrics include velocity and acceleration during movement.

  • Kinetics:

    • Analysis of forces acting on the body.

    • Important concepts include ground reaction forces and torque generated during movement.

  • Neuromuscular Control:

    • Coordination between the nervous system and muscles that facilitates movement.

Common Movement Patterns

  • Movement Patterns include:

    • Squat: A foundational exercise emphasizing strength and stability.

    • Deadlift: Key for developing posterior chain strength.

    • Lunge: Essential for functional strength and balance.

    • Push/Pull: Fundamental patterns for upper body strength.

    • Jumping and Landing: Important for explosive power and control.

Identifying Faults and Inefficiencies

  • Poor Technique Examples:

    • Squat Faults: May include knees caving in, improper depth, and back rounding.

    • Deadlift Faults: Could include back rounding, improper hip hinge mechanics, and uneven weight distribution.

  • Common Causes of Movement Faults:

    • Mobility restrictions affecting range of motion.

    • Strength imbalances leading to inconsistencies in movement.

    • Motor control issues resulting from poor practice or learned habits.

Types of Feedback

  • Intrinsic Feedback:

    • Feedback derived from the athlete's own sensory systems (visual, proprioceptive, etc.).

  • Extrinsic Feedback:

    • Feedback provided by external sources such as coaches, video analysis, or technological devices.

  • Types of Feedback Timing:

    • Concurrent Feedback: Provided during the execution of the movement.

    • Terminal Feedback: Provided after the movement has been completed.

  • Forms of Feedback:

    • Verbal Cues: Spoken instructions or suggestions.

    • Visual Cues: Demonstrations or visual aids to illustrate correct technique.

    • Tactile Cues: Physical assistance or adjustments made by the coach to guide the athlete.

Effective Coaching Cues

  • Key Characteristics:

    • Clear, concise, and actionable instructions that athletes can easily understand.

  • External vs Internal Focus:

    • External cues direct attention to the effect of the movement (e.g., "push the ground away").

    • Internal cues focus on body movements (e.g., "flex your knees").

  • Examples for Common Exercises: Provided for various exercises to illustrate effective coaching techniques.

Technology in Feedback

  • Tools and Apps:

    • Hudl: A platform for game video analysis and feedback.

    • Video Replay Apps: Such as Dartfish and Hudl Technique allowing for detailed analysis of movements.

    • GYMAWARE: A technology providing performance monitoring and data collection in training.

    • Medic: A device focused on enhancing training through performance tracking.

    • Wearables and Sensors: Personal devices that provide real-time feedback during exercise.

    • TECHNOGYM: Fitness technology offering smart equipment for movement tracking and feedback.

Case Study

  • Focus on Squat Movement:

    • Analyze a squat to identify faults in technique.

    • Provide tailored feedback and cueing strategies to improve performance.

    • Document before/after scenarios to showcase improvement.

Integrating Feedback into Training

  • Methodologies:

    • Creating progressions and regressions to fit athletes’ levels of experience and skill.

    • Monitoring improvements through constant feedback processes.

    • Fostering athlete education and promoting autonomy in their training decisions.

Challenges and Considerations

  • Common Issues:

    • Overcoaching can hinder athlete development and confidence.

    • Recognizing athlete readiness and adapting the learning style to maximize engagement.

    • Balancing the amount of feedback with autonomy to allow athletes to grow independently.

1.5-mile Test

  • Parameters Recorded:

    • Resting heart rate.

    • Body weight in kilograms.

    • Recorded time of completion with necessary conversion from seconds to decimal (e.g., 11:12 = 11.2 where 12/60 = 0.2).

    • Post-exercise heart rate post-completion of the test.

Formulas Utilized
  • Larsen Formula for VO2max:
    VO2max = 100.16 + 7.30 imes ext{(males: 1, females: 0)} - 0.164 imes ext{(BW, kg)} - 1.273 imes ext{(time, min)} - 0.1563 imes ext{(HR, bpm)}

  • ACSM Formula for VO2max:
    VO2max = 3.5 + rac{483}{ ext{Time}}
