PNUR 104 - Theory 1 - Activity &
Exercise
What is Isotonic exercises? (Tone) - ✔️✔️- dynamic exercises
- muscles shorten and produces active movements
- improves circulation and blood flow
- examples: running, walking, swimming, cycling
- purpose: increasing tone, mass and strength: joint mobility and flexibility
What is isometric contraction? (measuring tension) - ✔️✔️- static or setting
- change is muscle tension, not in length or movement
- increases heart rate but not necessarily blood flow
- purpose: strengthening specific muscle
What is isokinetic exercises? (hard K - harder to do exercises against r____________) -
✔️✔️- resistive exercises
- muscle contraction/tension against resistances, can be isometric or isotonic
- example: lifting weights
What is aerobic exercises? (got lots of air) - ✔️✔️- intake of oxygen is greater than or
equal to body's need
- activities that require less oxygen then blood supply
- purpose: conditioning and fitness
- example: walking, jogging, dancing, and fitness
How does Growth and Development affect body alignment? - ✔️✔️- with maturity you
gain fine motor control
- pregnancy alters the center of gravity
- posture and bone density alters with aging with gradual loss of muscle tone, joint
mobility, decreased reaction time, decreased bone density (osteoporosis)
- Frailty: older adults
What is Balance and Stability? - ✔️✔️the ability to control the placement of the bodies
center of gravity to its support base
What is balance norms? - ✔️✔️- Maintained by mechanisms of equilibrium (sense of
balance) (affected w/ ear infections)
- Messages from the stimuli go to the reflex centre of the brain stem for interpretations
and results in reflexive responses to body imbalances
