Exercise and Muscle Performance01:27

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Stability of structures01:14

Stability of structures

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...
Stability01:28

Stability

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...
Muscle Coordination and Action01:24

Muscle Coordination and Action

Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement.
Movement Joints in Buildings01:27

Movement Joints in Buildings

Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...
Functional Classification of Joints01:09

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis
An immobile...

Summary
This summary is machine-generated.

This study found weak correlations between core stability, functional movement, and athletic performance. Core stability and functional movement assessments are not strong predictors of performance and should not be the primary focus of training programs.

Area of Science:

  • Sports Science
  • Kinesiology
  • Exercise Physiology

Background:

  • Core stability and functional movement are widely emphasized in fitness and sports for enhancing performance.
  • However, the direct relationship between these components and actual performance outcomes requires further investigation.

Purpose of the Study:

  • To determine the relationship between core stability, functional movement, and athletic performance in healthy individuals.
  • To assess whether core stability and functional movement screen (FMS) scores predict performance metrics.

Main Methods:

  • Twenty-eight healthy adults performed tests assessing core stability (flexion, extension, lateral), FMS (including deep squat, push-up, hurdle step), and performance (medicine ball throw, T-run, single leg squat).
  • Statistical analysis (p ≤ 0.05) was used to identify significant correlations between the different test categories.

Main Results:

  • Weak to moderate correlations were found between some core stability tests and performance metrics (e.g., single leg squat, T-run).
  • Several FMS tests showed significant correlations with specific performance tests (e.g., hurdle step with T-run and medicine ball throw).
  • No significant correlations were found between core stability measures and FMS scores.

Conclusions:

  • Core stability and functional movement, as measured in this study, are not strong predictors of athletic performance.
  • Current assessments may not adequately confirm the importance of core stability for functional movement.
  • While beneficial for injury prevention, core and functional movement training should not be the primary emphasis in fitness programs.
