The document discusses how exercise affects the endocrine system, emphasizing both immediate and long-term hormonal responses. Immediate responses include the release of adrenaline and cortisol, which prepare the body for exertion, while long-term adaptations involve increased growth hormone secretion and improved insulin sensitivity. Overall, exercise plays a crucial role in metabolic regulation, energy balance, and promoting overall health.

Introduction to Exercise and
Endocrine Mechanisms

5. 1-OVERVIEW OF
ENDOCRINE
The human body is a complex network of systems
that work together to maintain balance and
regulate various functions. One such vital system is
the endocrine system, which consists of a collection
of glands that secrete hormones into the
bloodstream

6. HORMONES AND
THEIR FUNCTIONS
Hormones are chemical substances produced
by endocrine glands that act as messengers,
transmitting signals to various parts of the
body. These hormones regulate a wide range
of physiological processes, including
metabolism, growth and development,
reproduction, stress response, and mood
regulation. Each hormone has a specific target
and triggers specific responses within the
body.

7. 2-HOW EXERCISE EFFECT
ON ENDOCRINE SYSTEM
Exercise plays a vital role in maintaining
a healthy lifestyle and has far-reaching
effects on various bodily systems. One
such system that is profoundly
influenced by exercise is the endocrine
system. exploring the immediate and
long-term hormonal responses to
physical activity.

Responses

Responses
Understanding Immediate and
Long-Term Hormonal Responses
to Physical Activity

9. 1-Immediate Hormonal
Responses
Immediate hormonal responses occur rapidly during and
immediately after physical activity. One of the primary
hormones involved is adrenaline, which is released from the
adrenal glands in response to stress or exertion. Adrenaline
increases heart rate, blood pressure, and blood flow to the
muscles, preparing the body for physical exertion so we called it
fight or flight" response, enhancing alertness and energy
availability to meet the demands of exercise

10. 1-Immediate Hormonal
Responses
Another hormone that plays a crucial role in immediate
responses is cortisol, often referred to as the stress hormone.
Cortisol levels increase during exercise to mobilize glucose and
fatty acids from storage sites in the body, providing fuel for the
muscles. While cortisol is essential for energy production during
exercise , but excessive or prolonged elevation can lead to
muscle breakdown and impair recovery.

11. 2-Long-Term Hormonal
Responses
Long-term hormonal responses to physical activity involve
adaptations that occur over days, weeks, and months of
consistent exercise. One of the most well-known long-term
hormonal adaptations is the increase in growth hormone (GH)
secretion. GH stimulates muscle growth, repair, and fat
metabolism, contributing to improvements in strength,
endurance, and body composition
.

12. 2-Long-Term Hormonal
Responses
Another hormone that undergoes long-term changes is insulin
sensitivity. Regular physical activity enhances insulin
sensitivity, allowing cells to more efficiently uptake glucose
from the bloodstream. Improved insulin sensitivity reduces the
risk of developing insulin resistance and type 2 diabetes
