muscular endurance

Question 1

muscular endurance

Answer 1

• ability to maintain muscular contractions or continue repetitive muscular contractions for an extended period of time to a definitive endpoint
• short term tests to isolate a specific muscle or muscle groups
• very set criteria
• tempo is often controlled by a metronome
• power for long periods of time

Question 2

muscular fatigue

Answer 2

• effects muscular endurance
• substrate utilization
• buffering capacity of muscle
• fiber type
• metabolic factors

Question 3

central and peripheral neural fatigue factors

Answer 3

• neural transmission issues
• tolerance to fatigue
• motivation and feedback
• facilitates production of force so over time it decreases so force decreases

Question 4

protocol restrictions

Answer 4

• selected time
• level drop off
• metronome setting

Question 5

maximal muscular endurance tests

Answer 5

• starts at an intensity that is maximal from the start and continues to a set limit or fatigue
• see how long you can go
• ex. speed sit up test

Question 6

submaximal muscular endurance test

Answer 6

• starts at an intensity that is less that the maximal from outset and continues to a predetermined limit
• ex. partial-curl up test

Question 7

rohmert’s curve

Answer 7

• shows why we do submaximal tests and get similar results
• starts high, low endurance
• low % of MVC, high endurance
• over time, even if you start out submaximally with a quick test, you will reach the top end of a score more quickly
• opposite for maximal
• lesser forces = get to fatigue

Question 8

tests of muscular endurance

Answer 8

• use free weights or a machine apparatus
• performed at %1RM to a predefined endpoint
• can be controlled for timing or tempo by a metronome
• controls the form of movement to isolate muscles / groups
• less than 10 seconds is strength , more than 20 seconds is endurance
• uses% of body mass to determine the initial load for the endurance test
• max reps = 15
• add total across exercises to dermine fitness

Question 9

abdominal endurance

Answer 9

• curl-up (CSEP) or sit up
• curl up is more safe of a procedure
• both a health (back) and fitness application and important for sport , occupations, and daily living
• associated to lower back fitness b/s abdominal muscles stabilize the trunk, spine,
• low abdominal endurance is related to low back pain

Question 10

protocol considerations for abdominal tests

Answer 10

• correct body position
• standardization of body, feet, and hand placement
• ROM pattern
• could restrain the hips or not
• if yes, hip flexors move, if no, ab muscles are more restricted
• timing is controled
• tempo is 1:1 or 25 curls per minute

Question 11

partial-curl up protocol

Answer 11

• 8cm for 40 year old’s and 12cm for under 40
• lesser ROM for adults and more for children
• if individual cannot reach the markers, record the distance they can do and use as a benchmark
• do not compare to normative data^
• 6-8cm for kids

Question 12

Biering-Sorensen’s back extension test

Answer 12

• modified for CSEP
• on bench flat on stomach or MCAFT steps
• support legs and maintain a horizontal position
• muscular endurance of the lower back
• time to failure or a time limit of 180 s
• isometric contraction

Question 13

push-up test of muscular endurance

Answer 13

• assesses general “upper body endurance
• hand placement is important
• under shoulders, shoulder width apart , arm/elbow at 90 degrees
• foot placement
• feet together hip width apart
• toe/knee for women
• hips for individuals who have a disability
• no timing, controlled at a rate of 20/min

Question 14

chin up test

Answer 14

• overhand grip, arms straight to chin above bar
• reps to failure
• variety of diff protocols to consider
• hand position, termination, metronome, isometric hang
