Spinning Questions with Detailed
Verified Answers Graded A+
CHAPTER GOALS Ans: - understanding how the energy systems of the body
are used in the spinning program
- learn about heart rate guidelines and monitoring
-explore cycling biomechanics and how they relate to riding a spinner bike
two main energy system Ans: aerobic
anaerobic
Anaerobic Ans: produces energy in the absence of oxygen
glycogen and phosphocreatine (PCr) are fuels used during anaerobic
metabolism
both glycogen and fats are used during anaerobic metabolism to yield
adenosine triphosphate (ATP)
glycogen Ans: carbohydrates
phosphocreatine (PCr) Ans: a phosphate ester of creatine found in vertebrate
muscle, where it serves to store phosphates to provide energy for muscular
contraction.

adenosine triphosphate (ATP) Ans: the energy currency of the body
Anaerobic and aerobic relationship Ans: there will always be a contribution
from both the aerobic and anaerobic systems at all intensities of exercises
adenosine triphosphate (ATP) - phosphocreatine (PCr) Ans: system is
responsible for the highest- intensity exercise
supplying the energy needed in activities such as a 100- yard dash, 25 yard
swim, or a sprint at the end of a bike race.
ATP- PCr Ans: is stored within the specific muscles activated during exercise
PCr break down Ans: is broken down to offer the body a source of phosphate,
which is donated to adenosine diphosphate (ADP) to make ATP
Benefits to training in the ATP-PCr system Ans: Development and
improvement of type Iix **( see fast glycolytic muscle fibers in glossary
section) muscle fibers, neuromuscular coordination, explosive power, speed
and anaerobic capacity
Anaerobic Glycolysis (Glycogen- lactic acid system) Ans: Primarily for intense
exercise lasting from approx. 30 seconds to 3 minutes
anaerobic/ glycolytic system and predominates when energy demands exceed
oxygen supply
Anaerobic/ glycolytic system example Ans: 400 m sprint on a running track or
an acceleration up a short hill on a bike
, 3|Page
system is fueled by metabolism of sugar (glucose) - used to produce ATP
Anaerobic activity anaerobic/ glycolytic system can... Ans: produce ATP longer
than the ATP-PCr system
however:
its resources deplete faster than those of the aerobic system
Pyruvate Ans: During anaerobic exercise, a by-product called pyruvate is
converted to a lactic acid which in turn quickly dissociates, or breaks down, to
lactate and a hydrogen ion.
(Breakdown of lactic acid)
Aerobic Ans: produces energy in the presence of oxygen
Additional potential benefts of aerobic training Ans: Include a stronger
immune system, increased endurance, decreased risk of heart disease and
diabetes, and improved mental state.
relationships between energy sty's and muscle fibers Ans: energy system,
work duration, fuel, muscle fibers
Aerobic + anaerobic Ans: Work duration: >10:00 minutes
Fuel: Glycogen + Fats
