Exercise Physiology Muscular System/respiratory system

What are the features of fast twitch 2x muscle fibre

• low force, high O2 content, long duration

• medium force, low O2 content, long duration

• max force, No O2 content, no capillaries,

• high force, no O2 content, high capillaries

A single muscle stimulation is known as

• Twitch

• Wave Summation

• Tetanus

• Type l Fibre

An isometric muscle stimulation that is constant is known as

• Twitch

• Wave Summation

• Tetanus

• Type lla

To increase blood flow which vessels have the ability to dilate

• Capillaries

• Arterioles

• Veins

• Coronary Artery

What would skeletal muscles use for fuel during aerobic respiration? 

• glucose
• fat
• creatine phosphate
• glycogen

An increase in temperature in the muscle also increases select which 2 apply)

• someone's ego

• range of motion of the muscle

• flexibility

• height

An increase in muscle temperature is cause by what (PICK TWO)

• less blood flow

• slower heart rate

• contractions

• breakdown of ATP

microtears are repaired using

• proteins

• carbs

• fats

• calcium

Which muscle fibres are used in this easy exercise

• Type l

• Type lla

• Type llx

• none

If breathing doesn’t increase it wont bring enough O2 and will build up CO2 causing a change in

• alkaline

• blood volume

• lower breathing rate

• acidic blood pH
