O Exam 2
notes resist, aerobic, jt mob, sx, gait, arthritis
Term | Definition |
---|---|
slow twitch (ST) | type I, red oxidative, large numerous mitochondria, triglycerides, enzymes for aerobic work, low myosin ATPase & glycolytic activity, lower calcium handling ability, shorter speed, good for endurance activities |
fast twitch (FT) | type II, white glycolytic, anaerobic, contract at a higher speed than type I fibers, high levels of myosin, ATPase provides energy for speed of contract & tension, low myoglobin content, few mitochondria, 3 subtypes |
3 elements of mm performance | strength, power & endurance |
overload principle | resistance applied must be great enough to at least briefly exceed the mm capacity- can be applied to both strength & endurance exercise |
reversibility principle | within a week or 2 "detraining" begins |
progression principle | intensity of the program must become progressively greater to continue making gains |
signs of fatigue | pain/cramping, trembling, movement slows, substitution, jerky movements |
general strength training recommendations for elderly | physician approval, close supervision initially, monitor vital signs, low resistance, low repetitions initially, progress by increasing reps, then by small amts of resist, avoid high resist to decrease stress on joints, train 2 or 3x/week w/48-hr rest int |
neural adaptations-increased motor recruit-skeletal mm adaptations | hypertrophy (sarcameres & mm cells get bigger, increase water & vascular content & proteins-actin & myosin-) hyperplasia -increased capillary density, increases in bone, ligament & tendon strength, specific decrease in osteoporosis |
DeLorme progressive resistance exercise (PRE) | 3 sets of 10 reps (10 rep max), arbitrary increase in resistance each week |
Oxford program | establishes the individual's 10 RM for the first set, moving to 75% of the 10 RM for the second set, and ending w/50% of the 10 RM for the 3rd set (10 reps ea) |
Knight (DAPRE) | four sets with variable reps & varying wts |
if mm endurance is goal then... | sets should increase, reps should increase, and resistance should decrease |
exercise parameters- order | after warm up, large before small |
mm setting exercises | low level isometric |
stabilization exercises | example: wall squat |
multiple-angle isometrics | otherwise mm would only build strength in one spot |
isometric exercise protocol-rule of tens | 10-second contractions for 10 repetitions with a 10 sec rest in between, gradually developing tension for 2 sec, maintaining a maximal contraction for 6 sec, then gradually decreasing tension for 2 secs |
PRE's-progressive resistive exercise | originally termed for Delorne's 1 RM with formula used to increase wts & reps-now a gen term for progression of wt & reps w/exercises |
max 02 Consumption | clinical measurement of body's ability to efficiently use oxygen during higher intensity activity (a measure of fitness) this imporoves when you exercise regularly |
ATP | produces energy by both aerobic & anaerobic pathways & is possible to improve the efficiency of both w/exercise |
sustained activity, moderate intensity, longer duration | more likely to be aerobic |
intermittant activity, short duration, high intensity | more likely to be anaerobic |
phosphagen or ATP-PC | anaerobic system used during brief bursts of activity lasting periods of 30 seconds |
glycolytic system | anaerobic for 30-90 sec bouts of activity that are relatively high intensity |
Type I fibers | slow twitch-are selectively recruited during low intensity activity |
Type II B fibers | fast twitch- selectively recruited during activities that involve power (factor of speed & force) |

children 6-17 should exercise | 60 min of moderate to vigorous daily exercise |
adults 18-65 should exercise | 30 min of moderate to vigorous exercise 3-5 days weekly |
