SPINNING TEST QUESTIONS AND CORRECT ANSWERS (LATEST
UPDATED)
CHAPTER GOALS: ANSWER: comprehending how the spinning program
uses the body's energy systems
Learn about monitoring and heart rate guidelines.
-examine the relationship between riding a spinning bike and cycling
biomechanics.
two primary energy systems: aerobic ANSWER
Anaerobic
Anaerobic: ANSWER generates energy without oxygen.
Anaerobic metabolism uses the fuels phosphocreatine (PCr) and glycogen.
Anaerobic metabolism uses both lipids and glycogen to produce adenosine
triphosphate (ATP).
ANSWER carbohydrates: glycogen
The phosphate ester of creatine, phosphocreatine (PCr), is present in vertebrate
muscle and is used to store phosphates for use as an energy source during
muscle contraction.
ATP, or adenosine triphosphate, is the body's energy currency.
Relationship between anaerobic and aerobic systems: ANSWER At all activity
intensities, both the anaerobic and aerobic systems will contribute.
For the most intense exertion, the adenosine triphosphate (ATP),
phosphocreatine (PCr), and ANSWER system are in charge.
providing the energy required for tasks like a sprint at the conclusion of a cycle
race, a 25-yard swim, or a 100-yard dash.
, The particular muscles used during exercise store ATP, PCr, and ANSWER.
The breakdown of PCr provides the organism with a source of phosphate, which
is then transferred to adenosine diphosphate (ADP) to create ATP.
Advantages of ATP-PCr system training include: ANSWER Neuromuscular
coordination, explosive power, speed, anaerobic capacity, and the development
and enhancement of type Iix **(see rapid glycolytic muscle fibers in the
glossary section) muscle fibers.
Anaerobic Glycolysis (Glycogen- lactic acid system) - ANSWER Primarily for
severe exertion lasting from about. From 30 seconds to 3 minutes
anaerobic/glycolytic system and takes over when oxygen supply cannot keep up
with energy needs.
An example of an anaerobic/glycolytic system is a 400-meter run on a track or a
bike acceleration over a little hill.
system is powered by the production of ATP through the metabolism of sugar
(glucose).
The glycolytic/anaerobic system can do anaerobic action. ANSWER generates
ATP for a longer period of time than the ATP-PCr system.
But:
Compared to the aerobic system, its supplies run out more quickly.
Pyruvate-ANSWER Pyruvate is a by-product of anaerobic activity that is
transformed into lactic acid, which rapidly dissociates, or breaks down, into
lactate and a hydrogen ion.
(Dissolution of lactic acid)
Lactic acid breakdown: ANSWER
Aerobic: When oxygen is present, ANSWER generates energy.
A stronger immune system, greater endurance, a lower risk of diabetes and heart
disease, and an enhanced mental state are some additional possible benefits of
aerobic training.
