Lecture 6 Flashcards
What is muscular strength
-the largest force that a muscle or group of muscles can generate during a single contraction
Example of muscular strength
-lifting groceries
What is muscular endurance
-the muslces ability to continue performing successive exertions or repititions against a submaximal load
Example of muscular endurance
-climbing stairs
-carrying groceries from car to fridge
What is muscular power
-the muscles ability to exert force per unit of time
-product of the force and the velocity of muscle shortning
Example of muscular power
-functional independence
What is muscular strength associated with
-marker of cardiometabolic risk
-associated with morbidity in young and older adults
What is low hand grip strength associated with
-sarcopenia
-functional limitations and disabilities
What is decreased lower extremity strength associated with
-inability to perform ADLs
-risk of hospitalization
What are higher levels of handgrip strength associated with in women
-40% lower risk of all cause mortality
What are higher levels of handgrip strength associated with in men
-30% lower risk of all cause mortality
What are higher levels of lower body strength associated with
-14% lower risk of all cause mortality
Why do we assess muscular fitness
-provide information about our baseline physical fitness
-identify weaknesses in certain muscle groups
-serve as a basis for designing individualized exercise training programs
-to monitor progress and improvements over time
What is musculoskeletal fitness testing specific to
-muscle groups testing
-velocity of movement
-type of contraction
-ROM used
-type of equipment used to perform assessment
What to do before beginning assessments for muscular fitness
-familiarize client with test procedure and equipment
What should warm up for muscular fitness tests include
-5-10 min of aerobic exercise
-dynamic stretching
-several light-intensity reps of specific testing exercise
What standardized conditions are included in muscular fitness assessments
-informed consent
-ensure general demographics have been collected
-aerobic warm up
-equipment familiarlization
-proper technique
-consistent repitition duration
-full ROM
-use of spotters when necessary
-documentation
What is a 1RM test
-requires client to exert maximal force dynamically though a ROM in a controlled matter with proper technique
Sources of error for muscular fitness tests
-client factors
-equipment
-technical skill
-environmental factors
Client factors
-control for effects of learning on performance
-encourage clients to achieve maximal effort
-allow for adequate rest between trials
Equipment
-equipment needs to be calibrated regularly
Technical skill
-correct any performance errors you see
Environmental factors
-room temp
-distractions
-pre and post-test should be at same time of day
Muscular endurance tests used in the lab
-grip strength
-predicted 1RM
-push up test
-plank test
-squat endurance tests
-vertical jump
