The Science and Benefits of Pre-Exercise Warm-Up

The Importance of Warming Up

Warming up is defined as preparatory activities aimed at activating the functional systems of the organism and preparing it for the subsequent application of more demanding loads.

Physiological Objectives

• Increase the temperature inside the muscle.
• Improve metabolic processes; organs of the body can produce energy more easily with the increase in temperature.
• Decrease muscle viscosity. The components of muscle coated with liquid at rest become less viscous when the muscle is heated.
• Increase the elasticity of muscle fibers.
• Increase enzyme activity.
• Increase vascularization (increased number of vessels supplying the muscle and greater blood flow), which achieves:
  • Improved oxygen supply.
  • Improved supply of nutrients.
• Facilitate the removal of waste substances.
• Increase muscle tone, which favors:
  • Improved speed of reaction.
  • Quicker response to a stimulus.
• Raise the physiological parameters for subsequent intervention:
  • Heart rate.
  • Systolic volume (the capacity of blood ejected per beat).
  • Respiratory rate.

Muscular Objectives

• Facilitate coordination between agonist and antagonist muscles.
• Prevent muscle injuries.

Psychoneural Objectives

• Serve as a kinesthetic reminder of the gesture to be performed.
• Increase the efficiency of neuromuscular transmission.
• Psychologically predispose the individual to the subsequent activity.

Sports Objectives

• Increase basic physical qualities (strength, flexibility, endurance, speed).
• Improve physical fitness and promote better sports results.

Specific Effects of Warming Up

• Effects on Muscle Contraction

  Warming up increases the efficiency of muscle contraction, improves metabolism, and enhances muscle strength.

• Impact on Coordination

  Coordination is improved after warming up, especially through the repetition of gestures that will be performed later during the activity.

• Effects on Injury Prevention

  Lack of warm-up predisposes the body to injury. Warming up affects antagonist muscles, ensuring that movement is controlled. If muscles are cold, they contract incompletely and slowly, negatively affecting the control of the movement itself.
