In the context of sport and physical activity, energy is best defined as:
a person’s ability to participate effectively in a particular sport or physical activity.
the power derived from fuels and used by the body to perform basic bodily functions and to produce movement.
the ability to exert maximum force in the shortest amount of time.
a specialised field of physiology that studies the short-term and long-term effects of exercise on the human body.
Lactate threshold is best defined as the point at which:
an athlete begins to experience fatigue.
lactic acid (i.e. lactate and hydrogen ions) begins to accumulate in the muscles at a faster rate than it can be removed (in the blood).
the body begins to produce lactic acid (i.e. lactate and hydrogen ions).
lactic acid (i.e. lactate and hydrogen ions) results in negative effects.
