Chapter 3: Exercise Physiology Flashcards
eight physiological principles required to improve fitness levels
overload progressive overload adaptation specificity variability (cross training) reversibility recovery overtraining
define overload
method through which you become more fit
a greater-than-normal stress or demand placed on a physiological system or organ, typically resulting in an increase in strength or function
affected by frequency, intensity or duration
this is required in order to see progress
define progressive overload
a gradual, systematic increase in the stress or demand placed on a physiological system or organ to promote fitness gains while avoiding the risk of chronic fatigue or injury
goal is to increase intensity, frequency, and duration slowly in order to prevent injury
define adaptation
the ability of a body part, system or organ to adjust to additional stress (overload) over time by increasing in strength or function
define specificity
training a certain part of the system or body in the way that it is overloaded
based on a goal, task-specific exercises should be implemented
can refer to metabolic systems, neurological patterns, or muscular contractions
have a purpose to every exercise
individualize your training
define reversibility
the body will gradually revert to pretraining status when exercise is discontinued
“if you don’t use it, you lose it”
detraining - reduction in fitness due to discontinuing exercise
define detraining
a reduction in fitness due to discontinuing exercise
define recovery
the body’s return to homeostasis
pertains to two segments of exercise training: recovery during exercise & recovery after an exercise session
define short-term recovery
the recovery during exercise - rest time between exercises
define training recovery
recovery time between exercise sessions
allows a more complete return to homeostasis at the cellular level
define overtraining
long-term reductions in performance and overall ability to exercise due to an imbalance in the amount of exercise and amount of recovery
typically involves reduction in performance and coordination, elevated resting heart rate and blood pressure, loss of appetite, soreness, increased illness or infection, issues with sleep, depression, and reduced self-esteem
What are the physical and psychological symptoms that commonly accompany overtraining?
reduction in performance and coordination, elevated resting HR and BP, loss of appetite, soreness, increased illness or infection, issues with sleep, depression, and reduced self-esteem
