Answer 1
Answer:

Answer:

oxygen

Explanation:

Oxygen is the specific substance needed for muscle activity that is delivered to muscles most effectively as a result of increased heart rate.

The control of heart rate (HR) during rest and exercise is a good indicator of the level of intensity at which the heart is working and is an important information about a person's health status. The heart muscle will respond directly to the body's need for oxygen and blood flow at different times in life, both to perform an exercise of a certain level of intensity and during periods of illness or external need, in which the body responds by sending blood flow to the muscles and / or organs that require blood and O2 supply. Heart rate is an important part of different physiological variables. For example, cardiac output forms with the stroke volume. Heart rate is also part of the double product.

Answers

A warm-up is a crucial component of any workout routine and involves performing light aerobic exercises and stretching to prepare the body for the upcoming physical activity.

Thus the correct option is A.

How to start a workout sesion?

Here's an summary of the reasons of why a warm-up is essential before a workout:

Increased Blood Flow and Muscle Temperature: Engaging in a warm-up routine raises the body's core temperature and increases blood flow to the muscles. This helps to deliver oxygen and nutrients to the working muscles, preparing them for the demands of exercise. Warm muscles are more pliable and less prone to injury.

Enhanced Range of Motion: Dynamic stretching exercises included in a warm-up help to increase flexibility and improve the range of motion of the joints. This can enhance exercise performance, prevent muscle strains, and allow for proper form during exercises.

Activation of Muscles and Nervous System: A warm-up routine activates the neuromuscular system, preparing the muscles and nervous system for the physical activity ahead. This activation can improve coordination, reaction time, and overall performance during the workout.

Mental Preparation: A warm-up not only prepares the body physically but also helps in mental readiness for the workout. It allows individuals to focus their attention on the upcoming exercises, mentally prepare for the intensity of the workout, and set specific goals for the session.

So A is the correct one.
