SPORT METABOLISM

Question 1

_________________________ -investigates the use and transformation of free energy in the body. *change in free energy from any reaction = energy released (byproduct) - energy used to create the reaction

Answer 1

BIOENERGTICS

Question 2

___________________ -foods must be continually consumed to maintain energy availability

Answer 2

ENTROPHY

Question 3

What are major forms of bodily energy:

Answer 3

MECHANICAL BIOCHEMICAL HEAT

Question 4

Competition can quickly deplete bodily energy: - - - - - -

Answer 4

Sweat > heat energy lost via evaporation Increased respiration >gases constrain heat energy Movement > Mechanical Energy is transferred to free form

Question 5

____________________________ -energy can only be transferred, not created or destroyed -In a closed system, enthalpy will be constant (human body is open) -free energy is limited by the efficiency of metabolism processes

Answer 5

LAWS OF THERMODYNAMICS

Question 6

From a training perspective biochemical reactions either: -_____________ -_____________

Answer 6

Release energy Require energy

Question 7

(ATP ADP + Pi + Energy)

Answer 7

RELEASE ENERGY

Question 8

(CP +ADP +ENERGY ATP+CP)

Answer 8

REQUIRE ENERGY

Question 9

______________________ -free energy is produced via processes that metabolize ATP -only source used by skeletal muscles -energy is released from the breaking of its phosphate bonds. -Resting muscle storage can fuel a 1rm attempt (3sec) - recovery is ~90 sec for resynthesis (requires energy)

Answer 9

ATP

Question 10

When it comes to the metabolic overview immediate energy needs are?

Answer 10

Anaerobic energy from Phosphagen

Question 11

Each energy pathway determines: - - - -

Answer 11

-the magnitude of potential force -the sustainability of potential force -The total force actually produced from the energy system -the rest intervals associated with system recovery

Question 12

________ and _________ are the fuel sources for the Phosphagen system

Answer 12

ATP & CP

Question 13

ATP & CP are the fuels source that is the driving factor when it comes to work. That work lasts how long ?

Answer 13

10-15sec

Question 14

ATP and CP are critical for _________&___________

Answer 14

Power and anaerobic sports

Question 15

____________ efficiency is improved via heavy ballistic training (type 2 overload)

Answer 15

Phosphagen

Question 16

______ programs reduce CP proficiency (hypoxia)

Answer 16

HIT

Question 17

___________________________ -anaerobic metabolism of glucose and glycogen via the glycolytic system -supports longer-duration work at moderate-to-high intensities (up to 90 sec) -requires 10 biochemical reactions; slower than CP system -advantage lies in its energy potential (400-500g) -rest periods are dictated by byproduct clearance rates

Answer 17

INTERMEDIATE ENERGY NEEDS
