Cards

Term

Vo2 Max

definition

how determined and improved

 

Definition

definition - serves as an indicator of aerobic and cardiovascular preformance

(greater aerobic capasity=greater ability to deliver and use oxygen)

 

- Primarily determined by genetics but can be incresed up to 30% w/training

Term

What is absolute Vo2 measured in?

 

What is Relative Vo2 measured in?

 

Why is realative Vo2 better?

Definition

Absolute Vo2 is measured in L/min

 

Relative Vo2 is measured in ml/kg/min

 

Relative Vo2 is better because it allows for comparisons among people with different body masses

Term
What are the Direct and Secondary indicators of Vo2 Max?
Definition

Direct - an observable plateau in Vo2 with increasing work loads

 

Secondary - RER above 1.15,

 

HR above predicted max ( 220 -age)

 

Volitional Fatigue (sometimes used, not as valid)

 

Term

What is RER or Respiratory Exchange Ratio and how is it used?

 

What do the values represented by RER indicate?

Definition

RER is the measurement of gas exchange at the mouth

 

Can be used to predict which macronutrient is being used during exercise to produce ATP

- .70 (100% fats)

- 1.00 (100% carbs)

- Resing RER is .8 (1/3 carbs, 2/3 fats)

Term

Vo2 Peak

 

when it occurs

 

Definition

Definition

If Vo2 max indicators do not occur then a Vo2 peak occurs

 

Vo2 reached by the subject but is not necessarily the max

Term
What is Bicarbonate Buffering?
Definition
- system that works to relieve the body of excess Hydrogen ions that comes from lactic acid dissociation(seperation)
Term
Vo2 equation
Definition

Vo2= (Vi x Fio2) - (Ve x Feo2)

 

Vi = volume of inspired air

Ve = volume of expired air

Fio2 = fraction of inspired oxygen

Feo2 = Fraction of expired oxygen

 

Term
RER equation
Definition

RER=VCO2/VO2

 

(just divided not times 2)

Term

Body composition definition

 

 

Definition
the relative contribution of fat mass and fat free mass to total body mass
Term

Two compartment Model

 

Fat Mass includes...

 

Fat Free Mass includes...

 

 

Definition

Fat Mass contains weight of subcutaneous fat, visceral fat and fat from the mylein sheath of the nerves

 

Fat Free mass contains weight of all fat free mass, bones, muscle, organs, water, connective tissue.

Term

Anaerobic definition

 

Why shouldnt we store atp?

 

Definition

The ability to life, grow where free oxygen isn't present.

 

ATP  is heavy!

Term
CP system and Glysolosis comparison
Definition

CP system is faster but less sustainableof ATP

 

Glycolosis is slower but more sustainable of ATP

Term
What determines the Anaerobic capasity
Definition
determined by the ATP  supplied by glycogenic pathway rather than the CP system
Term
What are the different types of muscle fibers and what are their characteristics?
Definition

Type 1-slow twitch oxidative fibers, low power, very fatigue resistant

 

Type 2a-fast twitch oxidative/glycolytic fibers, medium power, medium fatigue resistant

 

Type 2b-fast twitch glycolytic, high power, low fatigue resistant.

Term
Biomechanics definition
Definition
the study of biological phenomena using the methods of mechanics
Term

What is velocity and what is the equation for it?

 

What units is velocity measured in?

Definition

The rate of change of displacement

 

V=change in position/time

or

V=d/t

 

d=displacement

 

Units:m/s

Term

What is momentum and what is the equation for it?

 

Units?

Definition

The product of mass ( in kg) times velocity

 

Eq: m x v

 

Units kg*m/s

Term

What is Kinetic Energy

 

Equation

 

Units

Definition

The energy that an object possesses as a result of its ability to do work

 

KE=1/2mv^2

 

Units:kgm^2/s^2

Term

Acceleration

 

definition

 

Equation

 

Units

Definition

the change in velocity

 

a=change in velocity/time

 

Units:m/s^2

Term
What is a neuron made up of and what do those parts do?
Definition

Made up of three parts

 

Cell Body-processes info +decides actions

 

Axon-takes info away from cell body

 

Dendrites-brings info towards cell body

Term

Afferent and Efferent and Interneurons

 

definition

Definition

Afferent (aahhhhh)sends impluses from sensory receptors to brain or spinal cord

(doesnt produce movement)

 

Efferent (effffort) sends impulses from brain or spinal cord to muscles

(produces movement)

 

Interneuron-connects afferent to efferent neurons

Term
Motor Control defiiniton
Definition
study of the organization of the CNS for coordination of movement
Term
Motor Learning definition
Definition
area of study focused on understanding the execution of motor processes and the variables that mediate their execution
Term
What are the types of feedback?
Definition

Intrinsic-inherent and occurs as a result of movement

 

Extrinsic-information from performance provided by artificial fashion

Term
What are the two types of extrinsic feedback
Definition

Qualitative-knowledge of results indicates if performance was: short/long, fast/slow ect.

 

Quanitative-knowledge of results indicated with direction or magnitude or error.

 

(Qualitative is always better)

Term
What is Motor Behavior?
Definition
the study of variables and processes that contribute to the performance or behavior of the actor
