Thesis Statement: The physiologic response to any form of physical activity depends on various
factors related to the environment as well as one’s body.
Speaker Notes

Slide One
Physical activity challenges the human body. The result is that the body responds in a
series of changes that are integrated. The response to physical exercise involves physiologic
systems (Marriott, 1993). Physical exercise requires the activation of the musculoskeletal
system. The activation of the musculoskeletal system is enabled by both the cardiovascular
system and the respiratory system (Glickman, Ryan, & Bellar, 2016). Engaging in frequent
exercise results in various adaptations that result in an increase in the efficiency and capacity of
the body (Marriott, 1993). Evidently, there various factors that affect the physiologic function of
the body during exercise. The factors relate to the physiologic systems that are affected when one
exercises.
Slide Two
When one engages in physical activity, their body temperature fluctuates.
Thermoregulation thus plays an important role in ensuring that the body temperature is regulates
(Marriott, 1993). Ideal environmental temperature enhances physiologic function. Ideal
temperatures avoid cold stress and heat stress. A warmup prior to beginning an exercise also
helps improve physiologic function. Putting on proper clothing can also help enhance
physiologic function by avoiding too much heat.

Slide Three
When engaging in any form of physical activity, the body requires enough energy. Poor
nutritional habits can thus limit the physiological response to physical exercise (Katch, McArdle,
& Katch, 2015). In addition, the body loses water through sweating. Failure to properly hydrate
the body limits the physiologic function of the body. Extreme environmental temperatures create
heat or cold stress that limit the physiologic function of the body. Age is also a factor since as
one grows older, their body begins to experience limitations. Older adults are unable to recover
from dehydration effectively.
Slide Four
The body mas has an impact on physiological function at rest. In addition, the
composition of the body also plays an important role in defining the physiologic function at rest.
The human body composition is evaluated using various body components. The Behneke
reference man and reference woman evaluates the body mass, lean body mass, muscle and bone.
The model also evaluates the body fat (Katch, McArdle, & Katch, 2015). Diet and medications
also help in defining physiologic function at rest.
Slide Five
There various factors that affect the physiologic function of the body during at rest and
exercise. The factors include age, hormones, genderNutritional supplements also affect the
physiologic function both when exercising and when at rest. Gender has an impact on
physiologic function not.
Slide Six

WEEK 3 ASSIGNMENT 4
When one engages in any form of physical exercise, they need oxygen that aids in the
production of energy. The energy produced is in turn used to fuel the muscles. Oxygen is
supplied by the respiratory system in coordination with the cardiovascular system (Vega et al.,
2017). The pulse rate increases as well as the number of breaths taken. Blood is pumped at a
higher rate compared to when one is resting and this increases the body temperature. Muscles
also heat up due to the physical activity.
