MOD 2: Energy Changes during exercise

A collection of vocabulary flashcards designed to help reinforce key concepts related to fitness, performance, and physiology discussed in the lecture.

VO2 Max

The maximum volume of oxygen that an individual can utilize during intense exercise, an indicator of aerobic fitness.

Aerobic Exercise

Physical activity that relies on the use of oxygen for energy production, typically involving prolonged, moderate intensity effort.

Anaerobic Threshold

The exercise intensity at which lactic acid begins to accumulate in the muscles faster than it can be removed.

Lactic Acid

A byproduct of anaerobic metabolism, produced when glucose is broken down for energy in the absence of oxygen.

Efficiency in Exercise

The amount of work done per unit of energy consumed; higher efficiency means more work is done with less energy.

Biomechanics

The science that deals with the mechanical aspects of living organisms, often applied in sports to enhance performance.

Cardiovascular Fitness

The ability of the heart, lungs, and vascular system to deliver oxygen to muscles during sustained physical activity.

Interval Training

A training technique that involves alternating short bursts of intense activity with periods of rest or lower intensity.

Energy Systems

Different pathways that the body uses to produce ATP during various types of physical activity, including aerobic and anaerobic systems.

Ventilatory Threshold

The exercise intensity at which breathing rate increases disproportionately to the increase in exercise intensity.

Muscle Fiber Recruitment

The process of activating muscle fibers to produce movement, with slow twitch fibers recruited at lower intensities and fast twitch at higher intensities.

Hydrogen Ions

Particles released during the breakdown of glucose that can contribute to acidification of the muscles and fatigue during intense exercise.

Sports Technology

Innovations in equipment, clothing, and gear designed to enhance athletic performance and efficiency.

Fitness Testing

Assessments used to measure various aspects of physical fitness, including VO2 max, lactate threshold, and muscular endurance.

Cognitive Fatigue

The mental strain that can accompany physical exertion, potentially affecting performance during prolonged exercise.
