Questions and Answers

Which principle of exercise physiology suggests that gains made through training are lost when training ceases?

  • Overload principle
  • Principle of progression
  • Specificity of exercise
  • Reversibility of training effects (correct)

Why is rest and recovery considered essential in exercise physiology?

  • It primarily enhances the specificity of exercise.
  • It is necessary for the body to adapt and improve from the stress of physical activity. (correct)
  • It prevents the body from experiencing the overload principle.
  • It directly maximizes VO2 max without any training.

Which aspect of exercise physiology is directly related to understanding how the nervous system influences muscle movement?

  • Fueling for exercise
  • Delayed Onset Muscle Soreness (DOMS)
  • VO2 max testing

Flashcards

Exercise Physiology

The study of how the body functions during physical activity and adapts to chronic exercise.

Overload Principle

To see results, the body must be challenged beyond its current capacity.

Principle of Progression

As the body adapts, the level of challenge must increase to continue seeing improvements.

Specificity of Exercise

Only the muscles or systems trained will experience improvement.

DOMS

Delayed Onset Muscle Soreness, muscle pain occuring 24-72 hours after intense exercise due to small muscle damage and inflammation.

VO2 Max

The maximum amount of oxygen the body can utilize during exercise, reflecting aerobic fitness.

Fueling for exercise

what energy systems “fire” when you are walking v. running v. lifting? What does the body eat before, during and after a workout? Where does it come from?

Mind-Muscle Connection

The central nervous system (CNS) (brain and spinal cord) and the peripheral nervous system (PNS) work together so your brain sends signals to your muscles, telling them when and how to move.

Adaptation to Exercise

Adaptation occurs as the body becomes more efficient and stronger due to consistent training. Gains involve muscle hypertrophy (growth) and increased efficiency of the cardiovascular and respiratory systems.

Study Notes

  • Exercise Physiology studies how the body functions during physical activity stress.
  • It also examines how the body adapts to ongoing physical activity.

Strength Basis of Exercise Physiology

  • Overload principle: The body must be challenged to see results.
  • Principle of progression: As the body adapts, it must be continuously challenged to improve.
  • Specificity of exercise: Only trained muscles or systems will improve.
  • Rest and recovery is important for results.
  • Reversibility: Training benefits are lost without continued training.

Concepts in Exercise Physiology

  • Fueling for exercise involves understanding what energy systems are used during different activities like walking, running, or lifting.
  • It also addresses where energy comes from and how to increase it.
  • The "mind to muscle" connection explores how muscles respond to brain signals.
  • The central and peripheral nervous systems are also involved.
  • Muscle soreness, including DOMS (Delayed Onset Muscle Soreness), is investigated.
  • Adaptation to exercise is another concept.
  • Such as, how gains are made and how to train for more endurance.
  • Consideration of what energy systems are active when you are walking versus running versus lifting.
  • Understanding where this energy originates and methods to enhance it.
  • How muscles respond to brain signals is explored.
  • Reasons for its occurrence are investigated.
  • What occurs in the body when gains are made is examined.
  • Methods to train for enhanced endurance are considered.

Assessments

  • VO2 Max Testing measures the maximal oxygen consumption.
  • It indicates the amount of oxygen the body can take in, transport, and use to generate ATP.
  • VO2 max is reflective of overall aerobic fitness.
  • Higher VO2 max = better overall fitness
