Transcript of How Does Training Affect Performance

How Does Training Affect Performance?
Students learn about:
energy systems
alactacidsystem(ATP/PC)
lactic acid system
aerobic system
Students learn to:
• analyse each energy system by exploring:
– source of fuel
– efficiency of ATP production
– duration that the system can operate
– cause of fatigue
– by-products of energy production – process and rate of recovery
The human body requires a continuous
supply of energy both to meet the needs of its systems and organs and to power muscular contraction for movement.

Body energy is stored
in the chemical
bonds that join atoms
and is released
only as needed.

The transformation of food
(chemical energy) to energy
that the muscles can use
(mechanical energy) is the
role of energy systems.

The transformation of food
(chemical energy) to energy
that the muscles can use
(mechanical energy) is
the role of energy systems.

Energy provided by food is measured in kilojoules (kJ).
Carbohydrate and protein supply 16 and 17 kilojoules of energy per gram
Fat yields 38 kilojoules per gram.
When food is digested, it breaks down to sugars, amino acids and fatty acids.
ATP or adenosine-triphosphate is produced and represents the most important substance in energy production.

Jot down some points
you were unaware of
in the following
Video
ATP does not become a waste product
It has the ability to be quickly rebuilt or resynthesised
The body turns over ATP to the equivalent of 75 per cent of its weight during a 24-hour period
ATP needs to be continually rebuilt to enable an energy flow

DID YOU KNOW
The three systems that make ATP available are:
the alactacid system (commonly called the ATP/PC system)
the lactic acid system (glycolytic system)
the aerobic system (oxygen system)
