HES 105 Final - Learning Outcomes

I hate this class

Strategies for working towards sex and gender equity within our displine

* including diverse genders in research
* females
* trans individuals
* encourage more minority genders to pursue our discipline and support them
* Create a better understaning about the important of sex and gender to identity and physiology
* but it does not influence abilities

ATP-PCr

* Immediate Respones
* 300 kJ/min


* 45 kJ
* 10-15s

Anaerobic Glycolysis

* Short-term system
* 150 kJ/min
* 200 kJ
* 1-2 min

Cellular Respiration

* Long-term system
* 30-80 kJ/min
* 1500-5300 kJ
* 2+ hours

Blood Lactate

Reduced pyruvate

What does blood lactate do to the rate of anaerobic glycolysis

Allows for higher rates of glycolysis and ATP resynthesis

Tension > Load

Concentric/muscle shortening

Tension < Load

Eccentric contraction/muscle lengthening

Tension = Load

Isometric contraction/muscle stays the same

Dynamic Contraction

Moves the skeleton

Static Contraction

No moevement occurs

Isotonic contraction

tension stays the same throughout contraction

Isokinetic contraction

Velocity stays the same through contraction

3 Mechanical factors that influence development of muscles tension

1) rate of contraction

2) muscle action

3) joint position

3 morphological factors that influence development of muscle tension

1)cross-sectional area

2) pennation angle

3)muscle fiber type

3 neural factors that influence development of muscle tension

1) motor unit recruitment (number coding)

2) firing frequency (rate coding)

2) inter-muscular coordination
