What are the 10 benefits of warming up before exercise?
|
Increases degradation of oxyhemoglobin
Increases body temperature Increases blood flow to the exercising muscles Increases blood flow to the heart Decreases the viscosity of the muscles Causes and early onset of sweating Enhances the speed of transmission of nerve impulses Increases the blood saturation of muscles and connective tissues Prepares the cardiovascular system for upcoming more strenuous activity Prepares the muscular system for more intense activity |
|
|
What is the degradation of oxyhemoglobin?
|
Breaking down the chemical complex of oxygen and hemoglobin which results in the release of oxygen from the blood enhancing the delivery of oxygen to the exercising muscle.
|
|
|
Why is elevating body temperature before exercise beneficial?
|
It reduces the potential for skeletal muscle injuries and connective injuries since cold muscle and tendons have been shown to be more susceptible to injury,
|
|
|
Why is increasing blood flow to the heart in warm up beneficial?
|
It reduces the potential for exercise-induced cardiac abnormalities (e.g., electrocardiographic disturbances), reducing the potential for myocardial ischemia.
|
|
|
Why is decreasing the viscosity of the muscle beneficial?
|
Reduced muscle viscosity increases the suppleness of the muscle, thereby enhancing the mechanical efficiency and power of the exercising muscles.
|
|
|
Why is early onset sweating beneficial?
|
The earlier onset of sweating promotes evaporative heat loss and, as a result, decreases the amount of heat stored by the body. This will help to prevent an individual's body temperature from rising to dangerously high levels during (more strenuous) exercise.
|
|
|
Why is enhancing the speed of transmission of nerve impulses beneficial?
|
As nerve impulses are conducted at a faster rate, neuromuscular coordination tends to improve, resulting in better performance of certain motor tasks.
|
|
|
Why is increasing the blood saturation of muscles and connective tissue beneficial?
|
A higher level of blood reaching the muscles, tendons, and ligaments involved in the activity increases the elasticity of these tissues, resulting in a safer, more effective performance of stretching exercises.
|
|
|
How does warming up prepare the cardiovascular system?
|
Warming up helps to ensure that the cardiovascular system (heart and blood vessels) is given time to adjust to the body's increased demands for blood and oxygen.
|
|
|
How does warming up prepare the muscular system?
|
Warming up provides a transition from rest to strenuous exercise, and may reduce the likelihood that excessive muscular soreness will be a concomitant result of strenuous activity.
