Introduction to Safe, Efficient Movement: Key Concepts for Movement Analysis

A set ofQUESTION_AND_ANSWER flashcards covering the lecture on efficiency, movement analysis, movement standards, correction prescriptions, and how to study safe, effective, and efficient movement in kinesiology.

What does efficiency mean in the context of movement and kinesiology?

The least amount of effort needed to accomplish a movement goal, aiming for movement that is safe, effective, and efficient.

Why is it important to identify what a learner or athlete isn’t doing correctly?

To design targeted strength, conditioning, rehabilitation, or training programs that correct inefficiencies and improve movement safety and effectiveness.

What biomechanical tools are mentioned for studying movement?

EMG (electromyography) and motion capture with reflective markers and cameras; though simpler, everyday observation is emphasized.

What is the first step in effectively analyzing a movement skill?

Break down and describe the skill into parts and phases to understand how the body moves.

What is the Functional Movement Screen (FMS) used for in this context?

Providing a standard for normal movement to evaluate abnormal or atypical movement against that standard.

What does prescribing corrections involve in kinesiology practice?

Using movement standards and anatomy to determine fixes—stretching a tight muscle, strengthening a weak one, and comparing sides to guide correction.

What is the difference between simultaneous and sequential movement, with examples?

Simultaneous movements involve multiple body parts moving at once (e.g., squatting). Sequential movements involve a setup or wind-up and follow-through (e.g., throwing). Some skills (like shot put) combine both.

What does segment analysis refer to in biomechanics?

Examining which bone or segment moved more, the plane and axis of motion, and the type of muscle activity (isometric, concentric, eccentric).

What are the basic muscle action types discussed, and what do they do?

Isometric (stabilizing with no movement), concentric (shortening to produce movement), eccentric (lengthening to slow or control movement).

What movement activity categories are described, and give an example of each?

Balance activities (posture maintenance), Locomotion (walking/running), Projection (throwing), Object manipulation (writing or playing an instrument or using a racket), Weightlifting (lifting and lowering heavy objects), Power activities (maximal force in short time).

What is the difference between internal and external forces in movement?

Internal forces originate from the body's muscles and tissues; external forces come from outside the body (e.g., gravity, wind resistance, weight of an object).

How do educators use the concept of movement standards in practice?

They evaluate safe, effective, and efficient movement against standard benchmarks to identify deviations and prescribe corrections.

Why is it beneficial to relate analysis to the movement analysis project?

Because every aspect (describe, evaluate, prescribe corrections) feeds into and supports the movement analysis project deliverables.

What is structural kinesiology and why is it important?

The study of how muscles attach to bones and how bone structure influences movement, joint range of motion, and timing to produce safe, efficient motion.

What is the ultimate goal of kinesiology coaching as described?

To enable safe, effective, and efficient movement by understanding how, why, and when to apply corrections.

Why is it helpful to understand 'why' in coaching clients or patients?

It helps in making informed decisions, communicating clearly, and helping clients experience the science behind recommendations.

Why should analysis consider everyday movements like washing hair or buckling a seat belt?

Because movement analysis should reflect real-world conditions to improve safety and function in daily life, not just in the gym or lab.

What is movement standard used for when evaluating movement quality?

A reference point to determine whether a movement is safe, effective, and efficient and to guide corrective actions.
