NPTE Exercise Physio

Principles of Exercise & Training

QuestionAnswer
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
