exercise Flashcards
1.) ISOMETRIC Exercise
Contracting a muscle against an immovable object.
ex. push the wall as hard as you can
done with older individuals
2.) Isotonic
Contraction of muscles and movement of joints
LIFTING
improving muscle strength and muscle endurance
3.) Isokinetic
exerting effort to move muscles and joints against variable resistance
need specialized equipment that adjust the amount of resistance against force applied
4.) Anaerobic
5.) Aerobic
Physical fitness
- ) muscle strength
- ) flexibility
- ) aerobic fitness
Organic Fitness
refers to the inherited characteristic of the body
does not arise from actual engagement in activity
Dynamic Fitness
your ability to gain physical fitness through physical activity
Strength
how strong a muscle as able to contract
to improve strength need higher level of exertion with limited reps
Aerobic Fitness
Increased the amount of oxygen that you use during physical activity
increase the amount of oxygen that you can use and thats pumped to the heart
1953 Morris and colleuges
physically active male train conductors differered in heart disease from their sedentary counterparts
1963 Kahn
found that lower coronary heart disease death rates in more physically active post workers
1970
longshoremen coronary heart disease death rates were higher for works who had low levels of activity compared to those who were high active
Exercise protects against cancer
1.) Endorphin Hypothesis (depression& exercise)
predicts that exercise has a positive effect on depression in that it is the result of an increase release in beta endorphins following endorphins
2.) Monoamine Hypothesis ( (depression& exercise))
appears that exercise leads to an increase in the availability of different neurotransmitters. Serotonin NueroEp Dopamine
3.) Distraction hypothesis (depression& exercise)
Suggests that physical activity serves as a distraction from ones worries and depressive thoughts
1.) Thermogenic hypothesis (Anxiety and Exercise)
1.) Thermogenic hypothesis
rise in core body temp following physical activity that is associated with a reduction in anxiety symptoms in brain stem
2.) Changes of Pace
exercise provides someone an opportunity to change what is going on in ones life.
Biofeedback
meditation. Timeout therapy etc. Drinking at a pub. Changes in brain chemistry
3.) changes in brain chemistry
Stress Buffer
1.) cardio vascular response to stress
moderate blood pressure that accompanies stress
2.) Immune response to stress
moderation of pro inflamitory cytokines and how you deal with stress
Cognitive outcomes associated with physical activity
2.) increased expression of brain derived neurotrophic factor
BDNF acts on certain neurons in the CNS and PNS supports survival of existing neurons as well as encourage the growth of new neurons. Hippocampus, basal forbrrain, context. Areas associated with learning, memory and high level thinking. As well as long term memory
Abstinence Violation Effect
feelings of guilt and loss of control often experienced agter a person lapses into an unhealthy habit after a period of abstinence
Two types of exercise interventions
Behavioral and soical
