Sports Physio

Question 1

Any bodily movement produced by the contraction of skeletal muscles that result in a substantial increase over resting energy expenditure, according to the ACSM and CDC

Answer 1

Physical Activity

Question 2

Planned and structural physical activity designed to improve or maintain physical fitness

Answer 2

Exercise

Question 3

Systemic, planned performance of physical movements, postures, or activities
Aimed to treat medical conditions, and as for PTs we treat the functional problems

Answer 3

Therapeutic Exercise

Question 4

Ability to perform physical work
Base on energy expenditure during an hour of physical work

Answer 4

Fitness

Question 5

Measure of the body’s capacity to use oxygen
It is the maximum amount of oxygen consumed per minute when the individual has reached maximum effort

Answer 5

Maximum Oxygen Consumption

Question 6

What the muscles can do for you, what strength they can give when it is need, what power they can achieve in their performance of work, and how long they can continue their activity

Answer 6

Muscle Performance

Question 7

T or F Muscle strength is determined mainly by size or the cross-sectional area of the muscle

Answer 7

TRUE

Question 8

Formula to determine the amount of tension a muscle can perform is surface area cm2 multiplied to 3 to 4 kg/cm2,
200cm^2 how much tension can it generate?

Answer 8

600kg or 800kg

Question 9

Ability of contractile tissue to produce tension and a resultant force based on the demands placed on the muscle

Answer 9

Muscle Strength

Question 10

Greatest measurable force that can be exerted by a muscle or muscle group to overcome resistance during a single maximum effort

Answer 10

Muscle Strength

Question 11

40% greater than the contractile strength

Answer 11

Holding Muscle Strength

Question 12

• Ability of the neuromuscular system to produce, reduce, or control forces, contemplated or imposed during functional activities, in a smooth coordinated manner

Answer 12

Functional Muscle Strength

Question 13

Measure of the total amount of work that the muscle performs in a unit period of time

Answer 13

Power

Question 13

is the ability of the structures or segments of the body to move or be moved in order to allow the occurrence of roms for functional activities

Answer 13

Mobility

Question 14

T or F
Power is Also determined by the distance of contraction and the number of times it contract per minute

Answer 14

TRUE

Question 14

the ability to move freely, without restriction, used interchangeably with mobility

Answer 14

Flexibility

Question 15

Factors that could affect power

Answer 15

• Muscle contraction rate
• Resultant muscle force
• Force vs. Velocity

Question 16

How do we treat mobility?

Answer 16

o Passive is dependent on the soft tissues, either contractile or non contractile, this includes the muscles, ligaments, and nerves - someone or something is moving the joint patient or client
o Active depends upon the neuromuscular activation

Question 16

Ability to work for prolonged periods of time and the ability to resist fatigue

Answer 16

Cardiopulmonary Endurance

Question 17

o the measurement of the joint range

Answer 17

ROM (Range of Motion)

Question 17

a measurement of the joint range to a functional activity

Answer 17

Functional ROM

Question 18

the correct timing and sequencing of muscle firing combined with the appropriate intensity of muscular contraction

Answer 18

Neuromuscular Coordination

Question 18

T or F
For dynamic balance we ask the patient to sit quietly and maintain the position for a certain amount of time, sitting is the first level

Answer 18

FALSE
For static balance we ask the patient to sit quietly and maintain the position for a certain amount of time, sitting is the first level

Question 19

The interaction of the sensory and motor systems

Answer 19

Neuromuscular Control

Question 19

o The ability of the neuromuscular system though synergistic muscle actions to hold a proximal or distal body segment in a stationary position or to control a stable base during superimposed movement

Answer 19

Stability

Question 19

o The ability to align body segments against gravity to maintain or move the body within the available base of support without falling
o The ability to move the body in equilibrium with gravity via interaction of the sensory and motor systems

Answer 19

Balance or Postural Equilibrium

Question 20

T or F
For a dynamic balance, the next level is to ask the patient from sitting to standing

Answer 20

TRUE

Question 21

Components of physical function

Answer 21

1. Muscle Performance
2. Mobility or Flexibility
3. Neuromuscular Control or Coordination
4. Stability
5. Balance or Postural Equilibrium

Question 21

T or F
Type 1 muscle fibers have less extensive blood vessel system and capillaries, More mitochondria, and less myoglobin

Answer 21

FALSE
More extensive blood vessel system and capillaries
More mitochondria, More myoglobin

Question 22

Which is not a characteristic of a Type I Muscle Fiber?
o Red muscle fibers, rich in blood vessels
o Slow twitch muscle fibers
o bigger in size

Answer 22

o Smaller in size
