Risk factors for CHD

Day 6 Make March Memorable

What factors can increase the risk of CHD??????

 FATTY DIET

STRESS

SMOKING

SEDENTARY LIFESTYLE



OBESITY

BAHL

Day 5  Make March Memorable

What is BAHL?

Balanced Active Healthy Lifestyle

WE ARE NOT TALKING ABOUT SKILLS!!!!!!

so what are we looking at.......

healthy diet
loosing weight
30mins x 5 days (adults)
friends active
role models
5 a day fruit and veg
particpation
lifelong activity

Atherosclerosis

Day 1 Make March Memorable

Atherosclerosis

Its the narrowing of the lumen in the arteries

because of...........................

The chlorestorol build up on the artery wall

so a plaque forms

causes........

blood clots

and

high blood pressure/heart attack

WAT - 3.8km running line.  #boyMoMwelldone

Mix of muscle fibre types

Day 28 Face February Fighting

How does the mix of muscle fibre types determine the success of the performer?



A mix of fibres good for aerobic and anaerobic events.  Team games.

Slow twitch (slow oxidative) - endurance activties, marathon

Fast Twich (fast oxidative) - anaerobic/explosive events, 100m


WAT - LAST FFF day, its been emotional.

Blood pressure

Day 24 Face February Fighting

Defintion of Blood pressure.....

Blood Flow x Resistance
or
The pressure exerted by blood on the walls of a blood vessel.

Measurements
                     Average              Hypertension
Sytolic            120   mmHg            140   mmHg
--------           -----                       -----
Diastolic           80    mmHg            90    mmHg

WAT - hockey practice  #gettingslightlybetter #sandintrainers

Ways to improve joint stability.....

Day 21 Face February Fighting

How can joint stability be improved?

Think about the parts of a joint first......
Then think bigger/stronger/thicker.


Muscle
They get bigger - hypertophy.  Plus more fibres.

Ligaments
They get stronger & more elastic

Tendons
Tendons become stronger

Cartilage
Increase thickness of articular/hyaline cartilage

How is oxygen and carbon dioxide in the blood?

Day 20 Face February Fighting

Oxygen Transport.......

Combines with Haemoglobin to form Oxyhaemoglobin
or
Dissolved in blood plasma




Carbon Dioxide transport......

Combines with Haemoglobin to form carbominohaemoglobin
or
Dissolved in blood plasma
or
dissolved in water as carbonic acid.


WAT - Badminton with son and cricket net (no DIY) - 120 mins.

Changes due to Neural control

Day 17 of Face February Fighting

 

WAT - fence fixing failed so had to do again! #rubbishatDIY

Neural control

Day 16 of Face February Fighting

NeuRal Control

 

3 Receptors

Baroreceptors     Chemorecpetors      Proprioreceptors

Detect changes in……………………………….

Increase in Blood pressure            

Chemical changes 

decrease in pH,

increase in CO², Lactic Acid    

 

Increase in movement

                              

They all inform either

CARDIAC CONTROL CENTRE            -    HEART!

RESPIRATORY CONTROL CENTRE    -    BREATHING!

WAT - fixed the fence. #nothappywithwind

 

 

Motion

Also linear can be striking a ball through its centre of mass.
Also angular can be striking a ball off centre of mass causing spin or swerve.

WAT - 75.18mins. 2.9km.  Running the line in my lad's game this morning!!!!

Stroke Volume

Day 12 of "Face February Fighting"

Stroke Volume

• What is it?

 
The volume of blood ejected by the heart ventricle(s) per beat.

• How is it measured?

In ml -
an average value at rest is between 60ml and 90ml
a maximal value would be between 120ml - 200ml.

• What changes take place from rest to max?

SV increases
SV plateau's during sub max work
SV decreases at very high intensity exercise because HR is too high for ventricles to fill fully

WAT - focussed on psychomotor abilites to help for a fine motor skill.  Playing the piano!
(see email for evidence)

Venous Return and its affects on performance

Day 11 of "Face February Fighting"

What is venous return.............?
            Blood   back (to heart)


4 methods.......

1. Skeletal Muscle Pump
2. Respiratory Muscle Pump




3. Valves in Veins to prevent backflow


4. Gravity helps in veins above the heart.



How does it affect performance?????

Well.......

Stroke volume is dependent on Venous return
so.......an increase in VR will increase SV.

It doesnt take....

to work out that

Cardiac Output = SV x HR

So any increase in SV will have to increase Cardiac Output.
Similiarly with any increase in HR too!!!!

HR increases due to the SA node firing more because of the stretch of the atrial wall with the increase in VR.

If the atrial walls are stretched more then so will the ventricle walls so more blood is pumped out per beat............. SV!!!!!!!
 WAT - 40mins Dodgeball with y10!!!

Osteoarthritis

Day 7 of "face February fighting"



 WAT - 30 mins
Knackerball (TENNIS AND SQUASH MIXED) - i know what you are thinking.........
he can play it due to modifed/adjusted motor programmes using the schema theory.

WAT   (2)  8   5   7

HAL    (1)  6   7   5

 

#greatgame #unluckyHAL

Warm up & skeletal muscle

Day 3 of "Face February Fighting"

 

WAT - Hockey practice 60 mins

Respiration Tarsia

Cardiovascular and Respiratory response to exercise

Here is a diagram that puts everything together when talking about the response of the heart and breathing when exercising and the regulation of the heart and breathing rate.

External and Internal Respiration

The video shows clearly using animation and voice over the difference between the two processes.

The Respiratory System

 
Here is a pre-view of some of the stuff that we will be covering over the next few weeks.

CHD conditions

Coronary heart disease (CHD) is the UK's biggest killer, causing around 82,000 deaths each year. About one in five men and one in eight women die from the disease.

http://www.nhs.uk/Conditions/Coronary-heart-disease/Pages/Introduction.aspx

We can split it up into discrete areas for revision!

This post is about conditions of CHD, more will come on Risk Factors and Preventions........

Description

CHD is the  failure of the coronary arteries to supply enough oxygen to the myocardium/heart muscle. 

It is the depositing of fatty materials in the coronary arteries of the heart causing a blockage.

Conditions

Angina

Chest pain caused by the partial blockage of coronary artery

which ........

causes lack of oxygen to myocardium or heart tissue


Heart attack or myocardial infarction or cardiac arrest

sudden and severe restriction / complete blockage of oxygen supply to myocardium (heart tissue)

arteriosclerosis

a condition where the walls of the coronary arteries become thicker or hard or less elastic

atherosclerosis

most common cause of CHD

and it is......

the accumulation of fatty deposits or cholesterol or plaque on walls of coronary arteries

which.....

leads to narrowing or blocking of the lumen or blood vessels

and it turn can.......

leads to stroke or heart attack or myocardial infarction
