Mod 6 Flashcards
Role of vitamins and benefits
- essential for maintaining bodily functions in small quantities
- help in energy release and metabolic regulation.
- Chemical compounds the body is UNABLE TO MANUFACTURE → need to be consumed.
Consumption of vitamins CONS
- The body requires limited amounts: excretes & a waste.
- Vitamin A & D can be dangerous.
- false sense of security for those eating poorly.
Less adequate than vitamins in fruits and vegetables: some may use it as a replacement.
Water soluble vitamins(B&C) are excreted in urine if in excess.
fat soluble nutrients (A&D) can be stored in the body, causing pain, nausea, headaches and fatigue if consumed in excess.
Role of minerals and consumption benefits
Chemical compounds essential in bodily functions.
Iron
Calcium
IRON: help deficiency women, weight training, endurance athletes.
CALCIUM: bone density issues, estrogeon.
Cons of mineral consumption
adequate diet counters any need for calcium or iron tablets.
IRON: too much = toxic, lean meat and leafy greens.
CALCIUM: found in abundance of diary products.
Role of protein and benefits of shake.
- essential for recovery, helps muscle GROWTH, MAINTANCE, REPAIR
- absorbed quicker, practicle
Cons of protien shakes
- contains carbohydrate components, which should be considered.
- unregulated content
- impair kidney function
- weight gain.
Creatine and benefits
has been proven to be beneficial for ATP sports / lactic acid dependency such as sprints or weight training.
a naturally occurring product.
helps supply energy to muscles.
exhausted quickly.
Concerns of creatine
- overdose: kidney
- cramps
- dehydration
- no long term studies.
How the body prepares itself when stressed
Stress readies the body for action inclining the production of adrenaline. In response, the body:
Increases blood supply to skeletal muscles.
More oxygen to lungs
Increases glucose production: provides extra fuel.
Increases sweat production
Tightens muscles.
Characteristics of a learner
PE chap
- prior experience: application of past skills or knowledge
- confidence: self belief copy mechanisms, prevents negative influence of others
- hereditary: % muscle fibres, somatotype, height, gender, race, information process capacity.
- ability: perception (reading play), precision.
- personality traits: self discipline, focus, determination
Aerobic training effect on performance
Allow the athlete to perform at higher workloads without fatigue for longer periods as they progressively become a lower intensity by….
- improving waste removal
- increasing delivery of oxygen to working muscles
- improving lactic acid inflection point
- involving large muscle groups.
mHR for aerobic training
60-85% mHR
Pros of circuit training
It can improve the aerobic system altogether or specialise to meet certain needs such as improving: strength Endurance Flexibility coordination
Can incorporate skill and fitness components → beneficial for sports.
mHR from anaerobic training
85 % mHR
1:3 work: rest
Short duration, high intensity.
Anaerobic training effect on performance
IMPROVES STRENGTH, POWER AND SPEED: further and faster throws and kickers.
IMPROVES RECOVERY RATE:\ the rate at which the muscle deals with pyruvic acid and removes lactate from the muscle.
INCREASES PC STORES
SPEEDS UP GLYCOLYSIS: Increases the rate ATP is receives, allowing higher intensity to be maintained for longer
