Principles of Exercise & Training
Question | Answer |
---|---|
Define Isometric Contraction | A static contraction at a particular point in ROM |
What type of patient should NOT do isometric exercises? | Pts with cardiac & vascular disease due to sharp rise in BP and increased workload on heart. (Vasalva maneuver should also be avoided.) |
Define Isotonic Contraction | Occurs throughout ROM with the same weight/resistance and variable speeds |
Types of Isotonic Contractions | Concentric & Eccentric |
Define Isokinetic Contraction | Occurs at constant, preset speed with variable weight and accommodates as the force of contraction varies throughout ROM |
Manual Resistive Exercise elicits which type of contraction, essentially? | Isokinetic: due to the variable resistance provided by therapist or trainer. Machine isokinetics are more objective & less variable. |
What are the cardiac training effects of Aerobic Exercise? | -Decreased resting & submax HRs - Reduced diastolic & systolic BP at rest & submax - Increased cardiac output & stroke volume |
What are the pulmonary training effects of Aerobic exercise? | - Increased tidal volume - Decreased ventilation rate during submax exercise - Increased O2 extraction from blood |
Define Karvonen's Formula | THR = {(Max HR - Resting HR) x % desired training intensity} - Resting HR |
Temperature of pool for intense aquatic training | 27-28 degrees Celsius or 81-83 degrees Fahrenheit |
Temperature of pool for therapeutic aquatic training | 33-34 degrees Celsius or 91-93 degrees Fahrenheit |
What are the 4 factors that affect training? | F - Frequency I - Intensity T - Time (Duration) T - Type |
