LAB EXAM 2: WINGATE Flashcards
true or false: only aerbic power is believed to be an imporatnt component of physcial fitness
no , anerobic also
what is the most widely used test for assessing a subjects anerboic capacity and fitness
wingate anerboc test
what is the fucntion of the wingate test
assess anaerbic capacity and fitness
assess physiological and cognitive responses to supra maximal exercise
Measures one’s ability to use
anaerobic sources of energy to do
work, to generate power.
what is the winngate test
30 sec of maximal all out cycling (or cranking with arms) against a resistance that is proporional to body weight of the subejct
what is the main result of the WANT
NUMBER OF PEDAL REVOLUTIONS
true or false: muscle fibers have enough ATP to last for a couple minutes of intense muscular work
false, just a few seconds
what is used to replenish atp stoes
tthe phosphocreataine system (PCR)
how long cvan the adenosite triphosphate PCR system give energy for
allows for 5-10 seconds of intense muscular work
once the ATP PCR is deleted, what kicks in
the anerobic glyclotic system
when is the anoerboic glyoclity system highly active
between 5-50 seconds
how does anaerboic glycolisis allow for ATP production
without oxygen
probides ATP via the breakdown of glucose (glycolysis) and glycogen (Glycogenolysis) in the musclr)
what happens when gluocse is used as a fuel in the absense of oxygen
lactate is produced as a by product
what happens when there is an accumatulation of lactatte
fatigue
how long is recovery
depending on subjectstraining level, 1-2 minites
explain the immediate energy system
. Immediate energy
• Alactic System (ATP-PCr: adenosine triphosphate/ phosphocreatine)
• Fast pace, low yield (1 enzyme - 1 step) – 5 to 10 sec
explain the short term energy
Short-term energy
• Lactate-Forming System (glycolytic anaerobic; short-term glycolytic)
• Moderate pace, moderate yield (11 enzymes - 11 steps) – 5 to 50
sec
explain the long term energy
Aerobic system is slow pace, high yield
