muscle endurance

Question 1

relative muscle endurance

Answer 1

curl-ups
bent knee sit ups in 1 min
pull ups, modified pulls us and flexed arm hang
push ups
dips
%1 Rm to failure
% of body weight (repetitions to failure)

Question 2

50th percentil for bent knee sit ups in one inute

Answer 2

M=40

F=35

Question 3

absolute muscle endurance

Answer 3

YMCA bench press test

NFL combine test

Question 4

YMCA bench press test

Answer 4

80 pounds to failure for males
35 pounds to failure for females
all reps are conducted with a metronome at 30 beats per minute

Question 5

NFL combine test

Answer 5

225 pounds to failure

Question 6

curl ups (crunch test)

Answer 6

supine with knees bent to 90 degress
arms by side and hand flat on teh floor fingers facing forward
fingertips touching the near edge of a strip of tape place at right angles to the body
a second strip of tape is placed either 3 or 4 inches away
metronome of 40 bpm
low back flat on floor throughout with trunk lifted to about 30 for each curl up

Question 7

what two variables did researchers use to investigate the safety and efficacy of 12 different abdominal exercises

Answer 7

MEG activity during execution of the exercises

lumbar and spinal compression during the exercises

Question 8

what 12 abdominal exercises did researchers study

Answer 8

straight leg sit up
bent leg sit up
curl up with feet held
curl up, free feet
quarter sit up
straight leg raise
bent leg raise
dynamic cross kne curl up
static cross knee curl up
hanging straight leg raise
hanging bent leg raise
ixometric side support

Question 9

what are the conclusions for the abdomincal exercise research

Answer 9

no single exercise recruited all abdominals simultaneously
anchoring feet did not make a difference
no differences in lumbar spinal compression between st. leg and bent leg sit ups
straight and bent leg raises while supine were not recommended due to high lumbar compression effects

Question 10

standard push ups

Answer 10

hands shoulder width apart
back straight
head neutral
on balls of feet
lower until chin touches mat (elbows at 90)

Question 11

relationship between absolute strenght adn maximum number of push-ups

Answer 11

push-up number alone is a weak to poor reflection of absolute strength

Question 12

relationship between maximum number of standard push ups, modified pushups, and relative strength

Answer 12

it appears that the maximumnumber of push-ups is a more accurate expression of a person’s relative strenght

Question 13

relationships between number of traditional pull ups and relative strength

Answer 13

it appears that pull-up tests are measures of relative strength and not absolute strength or relative muscle endurance

Question 14

the relationship between the modified flexed arm hang timed to 90 degrees of elbow extension adn relative isometric strength

Answer 14

the flexed arm hang is a test of relative isometric strength and scores do not suggest any type of absolute strenght or any type of muscle endurance
