Immediate Effects Of Exercise on the Muscular Syst
-Increases the body's demand for oxygen and glycogen (muscles need more fuel to function)
-Extra Waste Products Are Produced (eg. lactic acid)
Define ISOMETRIC muscle contraction!
-Muscle contraction which results in increased tension but the length does not alter
Define ISOTONIC muscle contraction?
-Muscle contraction that results in limb movement
Long Term Effects to MUSCULAR SYSTEM of particpati
-Increased Muscular Endurance
Soft Tissue Injuries - strain & sprain
-you STRAIN a MUSCLE
....and SPRAIN a JOINT :)
(eg. twisted ankle = sprain)
When would a performer experience reversibilty?
-During time taken off sport due to illness/time taken off training
Why is CARBOHYDRATE a better energy source than FA
-Carbohydrates release energy quicker
-Their energy can be used in both aerobic and anaerobic activity
Physical benefits of taking part in physical activ
-Contributes to good physical health
- improve cv fitness
-improve muscular strength/endurance
-improve body composition
SOCIAL benefits of taking part in physical activit
-Mix wih others
-make new friends
-meet current friends
-work with others
MENTAL benefits of physical activity
-relieve/prevent stress and tension
-increase self-esteem and confidence
-help the individual feel good
-contribute to the enjoyment of life
INFLUENCES ON TAKING PART
-Health & well-being
SPORT ENGLAND: Start, Stay, Succeed
-START: increase participation in sport in order to improve the health of the nation, with a focus on priority groups.
-STAY: retain people in sport through an effective network of clubs, sports facilities, coaches, volunteers and competitive opportunities.
-SUCCEED: create opportunities for talented young performers to achieve success.
SPORTS PARTCICPATION PYRAMID
-Elite: this is where inidividuals reach sporting excellence. pyramid narrows as fewer people take part in this level. Governing bodies of sport are responsible for development at this level.
-Performance: during this stage young people start to concentrate on specific skills & develop talent in specific sports. Quality coaching is an essential part of player development at this level.
-Participation: this stage is where young people begin to participate reguarly in a specific activity for enjoyment. Sports club become important at this stage as they make the link to the next stage of development.
-Foundation: base of the pyramind. learning/experiencing basic sporting skills (multi sports sessions, primary PE lessons)
-A form of physical activity which maintains or improves health and/or physical fitness
7 Principles of training :)
4 MICRO NUTRIENTS
weight loss as a result of physical activity is ac
-Working harder than you normally do
-Using more calories than taken in
FACTORS AFFECTING OPTIMUM WIEGHT
6 performance enhancing drugs
-peptide hormones (eg. EPO)
Side effects of anabolic steroids
-high blood pressure
-increased risk of heart attacks and strokes
-infertility in women
What do anabolic steroids do?
-mimic the male hormone testosterone and promote bone an muscle growth
What do beta blockers do?
-control the heart rate and have a calming and relaxing effect
Side effects of beta blockers?
-nausea and diarrhoea
-insomnia and nightmares
what do DIURETICS do?
-elevate the rate of urine production
Side effect of diuretics??
-dehyrdation (which can cause dizziness,nausea, headaches and muscle cramps)
-long term effects such as kidney problems
What do narcotic analgesics do?
-reduce pain, allowing a performer to continue to participate despite having an injury
Side effects of NARCOTIC ANALGESICS?
-loss of concentration
-loss of balance
-loss of coordination
-emotional effects (eg. hallucinations)
what do STIMULANTS do?
-effect the central nervous system (CNS), for example, increased mental and/or physical alertness
Side effects of STIMULANTS
-irregular heart beat
-increased heart rate
-high blood pressure
What do PEPTIDE HORMONES do?
-cause other hormones to be released
-(EPO) increase the number of red blood cells, and therefore the amount of haemoglobin) allowing the body to carry extra oxygen (increased aerobic capacity) and quickly disperse waste products & lactic acid - making it ideal for long distance events.
-(HGH) increase muscle development
Side effects of ERYTHOPOIETIN (EPO)
-thickens the blood making it difficult for blood to pass through the small capillaries and thus increases the risk of heart attack or stroke
Ways to Balance Competition.
-mixed or single gender
what is SYSTOLIC and DIASTOLIC blood pressure?
-SYSTOLIC BLOOD PRESSURE: maximum pressure in the arteries when the heart contracts and pushes blood through the aorta and into the body. Rises during activity as more blood is required by the body.
-DIASTOLIC BLOOD PRESSURE: pressure of the blood during the relaxation phase between heart beats (when the heart is at rest). It depends mainly on the elasticity of the arteries and quality of the vessels.
what is PULSE PRESSURE?
-the difference between systolic and diastolic blood pressure
Immediate effect of exercise on the body
-breathing becomes faster and deeper
-body temperature increases
-sweating starts (so body requires fluids)
-muscles begin to ache
Effects of REGULAR exercise on the CARDIOVASCULAR
-decreased resting heart rate
-increased heart recovery rate
-increased stroke volume
-reduced blood pressure
-more capillaries within the heart muscle
Factors that have a negative effect on the cardiov
-high cholesterol (which is caused by a diet high in animal fats)
-sedentary lifestyle and lack of exercise (hypokinetic disease)
Immediate & short-term effects of physical activit
-breathing quickens and deepens
-oxygen debt (the extra oxygen consumed after anaerobic activity to make up for the short fall)
