What is muscular strength
The maximal force/torque that can be generated by a specific muscle or muscle group,No single test exists for evaluating total body muscular strength (Principle of Specificity)
What is muscular endurance?
the ability of a muscle group to execute repeated contractions over a period of time, or to maintain a specific percentage of the maximum voluntary contraction for a prolonged period of time No single test exists for evaluating muscular endurance (Principle of Specificity)
What is muscular power?
ability to exert force per unit of time; .
Why test muscular fitness?
Provides info on muscular fitness compared to norms; Identify weaknesses / imbalances in muscle groups; Help design a resistance training program; Provide feedback on progress, which can enhance adherence.
How is muscular strength assessed?
Can be assessed dynamically or statically; Measurement Equipment: Free weights; Machines; Isokinetic machines / dynamometers.
What are static strength assessments?
Using a dynamometer, static strength can be assessed at any joint; Static strength is specific to the joint angle.
What is grip strength assessment?
Strength of both hands can be tested; however, usually the dominant hand is used.
What are dynamic strength assessments?
1-Repetition maximum (1-RM): greatest resistance that can be moved through a full ROM in a controlled manner; 1-RM has traditionally been the gold standard for assessing dynamic muscular strength; Can also use multiple RM (3-RM, 5-RM, etc); Can be done for any exercise, but common assessments include bench press, shoulder press, leg press, and squat.
What are muscular endurance assessments?
Can be assessed statically or dynamically; Static: Plank; Flex arm hang; Wall squat; Dynamic: Push-up test; Curl-up (crunch) test; YMCA Bench press test.
What is the YMCA Bench Press test?
35 lbs. barbell set-up for women, 80 lbs. for men; Metronome set at 60 bpm (30 rep/min); Spotter is necessary; Maximum number of reps prior to fatigue or breaking cadence is recorded.
What is the push-up test?
Push-up test.
