Which energy system is predominant during the Margaria-Kalamen Stair test?
Phosphocreatine (ATP-PC) System
In the wingate test, the appropriate resistance in kp is set at
body weight (kg) x 0.075
During high-intensity exercise lasting 15 seconds to 3 minutes, which energy system is predominantly used?
Glycogenolysis/ glycolysis
define anaerobic power
the rate of ATP use per given time without oxygen
Out of these options select all that show INCORRECT techniques for static and CM jumps:
1. participant jumps and lands forward or back
2. participant fully extends their knees during the jump
3. participant performs a countermovement which in the ready position for static jump
4. participant remains still for at least 2 seconds before initiating the jump
1 and 3
List the instructions for static jumps
Instructor says to step on to platform. They wait for 2 seconds then get in ready position with knees at a 90 degree angle. They count to 3 then the participant jumps and lands vertically and then steps off.
A fatigue index of 65% on the wingate test indicates
poor fatigue resistance
Which is TRUE about countermovement jumps
1. they minimize stretch-shortening cycle
2. they involve a preparatory dip to utilize stores elastic energy
3. they produce lower jump heights than static jumps
4. they are only useful in certain athletes
2
Describe a what a countermovement force-time curve will look like
a flat horizontal line that is the athletes body weight, the force curve drops below body weight line when initiating downward countermovement, curve rapidly increases above body weight line and reaches a peak, curve then drops back down to zero, to the right of the curve is the flight time it is horizontal and remains at zero.
the horizontal line shown after the large slope on a force time curve is the
flight phase
What are the 3 main uses of the counter movement jump test
performing profiling, neuromuscular fatigue, return from injury
What are the 3 correct sex-specific sites for skinfolds
Men: chest, abdomen, thigh
Women: triceps, suprailiac, thigh
What is the logical sequence of the tests
body composition, agility, anaerobic, aerobic
T/F can BMI tell us the fat distribution
false
which pattern of body fat distribution is considered as a higher indicator of CVD risks?
Android (apple shape)
Lower waist-to-hip ratio is generally associated with better cardiovascular and metabolic health outcomes
True
what is the minimum number of measurements required at each skinfold site
2
Which of the following statements described proper skinfold measurements technique
cycle through all measurements sites before taking the second measurement at any site
Toby wants to tets his upper-body muscular strength by measuring his bench press 1-RM. He tested it three times over the course of a week, at the same time of day and under the same conditions. His results were 300lb, 500lb, and 200lbs, respectively. What is the primary issue with the test
Test reliability
Caliper should always be place perpendicular to the skin fold
True
List the 7 standard skinfold measurement sites
Chest, abdomen, thigh, tricep, suprailiac, subscapular, midaxillary
What are the initial adaptations to the resistance training responsible for strength gains
increased number of muscle fibers recruited, increased rate of muscle fiber recruitment, increase synchronous recruitment of muscle fibers
name the three primary types of muscle actions
concentric, eccentric, isometric
Peter weighs 70 kg and his 1RM squat is 110 kg and john weighs 110 kg and his 1 RM squat is 200kg. who is stronger relatively and absolutely?
John is stronger in the absolute and relative sense
