Introduction to Functional Anatomy [0:00]
The module introduces the implications of functional anatomy in human movement science, building on previous discussions of the skeletal, musculoskeletal, and neuromuscular systems. It highlights the importance of understanding planes of motion, axes of motion, joint types, and how movement occurs. The learning outcomes include understanding functional anatomy and its significance, defining range of motion, flexibility, and mobility, and examining anatomical discrepancies and anthropometry. Functional anatomy provides the foundation for movement analysis by explaining the structural components and mechanisms within the human body.
Significance of Functional Anatomy [2:24]
Functional anatomy is significant for identifying vulnerable structures, understanding muscle functions, and recognising performance patterns. It has applications in ergonomics, lever systems, joint mechanics, assessments, and understanding injury mechanisms. Identifying vulnerable structures such as muscles, tendons, ligaments, and joints helps in understanding injury risks. Knowledge of muscle origin, insertion, and fibre direction is crucial for determining how muscles contribute to joint movement and force production.
Functional Elements: Range of Motion [8:17]
Functional elements ensure the body can move through the necessary range of motion to perform functional movements safely and efficiently. Key concepts include range of motion, flexibility, and mobility. Range of motion refers to the extent of movement achieved at a joint, measured in degrees. Adequate range of motion allows the body to move through the required range for functional movements. Range of motion assessments include using a goniometer and evaluating active and passive range of motion.
Functional Elements: Flexibility [13:34]
Flexibility refers to the ability of muscles, joints, and soft tissues to move through an unrestricted and pain-free range of motion. It ensures these structures can stretch, lengthen, or contract without limitations, allowing for smooth and efficient movement. Flexibility is assessed using tests like the sit and reach test, which measures lower back and hamstring flexibility. Adequate flexibility is necessary to maintain good form and execute techniques efficiently, such as shoulder flexibility for swimmers.
Functional Elements: Mobility [17:43]
Mobility refers to the ability of a joint or series of joints to move freely through their full range of motion. It involves the coordination of skeletal structures, muscles, ligaments, tendons, and other soft tissues to control movement patterns. Mobility is assessed through functional movement screening, which includes tests like squats, lunges, and reaches. Good mobility reduces the risk of overuse injuries, such as proper hip mobility preventing knee pain in runners.
Anatomical Discrepancies and Movement [21:09]
Anatomical discrepancies, such as variations in bone structure, muscle structure, or imbalances, can impact efficient movement execution. Understanding these discrepancies is important for tailoring training programs, rehabilitation, and injury prevention strategies. Joint shape variations can lead to hip or shoulder impingement, limiting range of motion. Differences in muscle length may cause muscular imbalances, affecting movement patterns. Limb length discrepancies can result in gait abnormalities, requiring custom orthotics or shoe modifications.
Anatomical Discrepancies: Hypermobility and Bone Density [28:07]
Joint hypermobility, or excess range of motion, can be advantageous in activities like gymnastics but may also lead to joint instability. Variations in bone density and strength can affect an individual's susceptibility to stress fractures. Low bone density increases the risk of stress fractures, requiring continuous monitoring and appropriate training programs.
Anthropometry and Its Implications [30:58]
Anthropometry involves the systematic measurement of physical dimensions and proportions of the human body. It provides valuable data for designing equipment, training, and rehabilitation strategies, and for assessing performance. Key measurements include height, weight, and limb length. Leg length is crucial for assessing gait mechanics and adjusting saddle height for cyclists. Arm span is significant in sports like basketball and swimming. Foot dimensions are vital in selecting appropriate footwear.
Anthropometry: Body Composition and Equipment Design [35:29]
Measurements of body fat percentage and muscle mass are essential for assessing an individual's body composition, which impacts performance. Shoulder width can affect swimmers' stroke mechanics. Anthropometric data also helps in designing equipment like tennis rackets and ergonomic chairs. Formula One car seats are designed to accommodate a wide range of body sizes and shapes. Anthropometric data is used in biomechanical modelling to simulate and analyse movement patterns, such as golf swing mechanics.
