Q

water- importance?
Effects of dehydration

A
  • accounts for 2/3 of b body weight and essential for chemical reactions to dissolve and move substances around the body
    -decreased plasma volume, stroke and increased temp and HR and lower endurance and strength

Q

What are anabolic steroids

A

group of synthetic hormones which resemble the male hormone testosterone and are taken to promote protein synthesis and muscle growth

23
Q

3 pros and cons of steroids

A

+ increased muscle mass and strength
+increased speed of recovery
+increased intensity and duration of training

  • irritability
    -liver damage
  • heart failure
24
Q

What is EPO

A

used to increase red blood cell production
already found in the body

25
3 pros and cons of EPO
+ increased red blood cell and haemoglobin count +increased O2 transport +increase in intensity and duration -increased blood viscosity -decreased cardiac output -decreased natural production of EPO
26
What is the Human Growth Hormone
synthetic product copying the naturally produced growth hormone
27
3 pros and ons of HGH
+ increased muscle mass and strength +increased fat metabolism +increase blood glucose levels -abnormal bone and muscle development -enlargement for organs leading to potential failure -increased risk of cancer
28
Physiological aids
used to increase the rate of adaptation by the body to increase performance
29
blood doping
method of increasing red blood cells via freezing blood taken out 4 weeks before comp
30
3 pros and cons of blood doping
+increase RBC count +increased O2 transport and capacity +increased duration and intensity -increased blood viscosity -risk of blood clots -decreased cardiac out put
31
Intermittent hypoxic training
athletes are a sea level but are put under low partial pressure conditions.
32
3 pros and cons of IHT
+ acclimatisation for events at altitude +increased RBC and haemoglobin +increased mitochondria and buffering capacity -any benefit lost when IHT stops -may lose motivation and training patterns -hard to reach normal work rates
33
Pre- event cooling aids
ice vets or cold towel wraps reduces over heating, reduces cardiovascular drift and thermal strain
34
injury treatment
ice packs, sprays
35
post event
ice baths used to decrease DOMS
36
3 pros and cons for cooling aids
+ reduces core body temp +decreased sweating and dehydration +decreased swelling -ice burns -hide injuries -reduced efficiency in elderly
37
What pre- event meal will an athlete have
3 hours before- slow digesting carb meal e.g oats 1-2 hours- smaller fast digesting carb meal e.g bagel
38
What during event event meal should an athlete have
Fast digesting carbs to maintain blood glucose levels e.g banana
39
What post event meal should on athlete have
Moderate and fast digesting carbs as recovery is aided by 1-1.5 g per kg of carb per hour
40
Pre and post raining meals
Pre- small meal with fast digesting proteins and carbs e.g whey protein and rice Post- within 2 hours, fast digesting carbs and proteins e.G protein shake
41
Glycogen/ carb loading
Involves the careful manipulation of carb intake a week before competition to maximise stores of glycogen in muscles and liver.
42
3 benefits and risks of carb loading
+increased glycogen stores +increased endurance capacity +delays fatigue -poor recovery rates in depletion stage -increased risk of injury -affects mental prep before comp
43
Effects of dehydration
- decreased heart regulation and increased temp -increased blood viscosity -increased HR -increased fatigue -decreased skill level
44
Hypotonic sports drink
Drinks that contain a lower concentration of glucose than the blood stream. Used for athletes who don’t need energy boost e.g gymnastics
45
Isotonic sports drink
Drinks that contain equal levels of glucose to the blood stream. Rehydrate and supply glucose used by middle distance runners and game players
46
Hypertonic solutions
Drinks that contain a higher concentration of glucose than the blood stream. Absorbed slower than water. Used post event by ultra distance runners to replenish glycogen
47
Creatine
Consumption of creatine mono hydrate to increase stores of pc to increase intensity and duration of performance
48
3 benefits and risk of creatine
+ increased PC stores +increased fuel for ATP/PC system +increased intensity n duration -increased weight gain -muscle cramps -water retention
49
Caffeine
Stimulant used to heighten the central nervous system and mobilise fats as fuel for aerobic energy
50
3 benefits and risks of caffeine
+ increased nervous stimulation +increased focus and concentration +increased mobilisation of fats -diuretic effect leading to dehydration -insomnia -gastrointestinal problems
51
Bicarbonate
An alkaline such acts as a buffer to neutralise the rise in Latin acid associated with intense anaerobic activity.
52
3 benefits and risks of bicarbonate
+ increased buffering capacity +increase tolerance to Latin acid +increased intensity and duration -possible gastrointestinal problems -unpleasant taste causing nausea
53
Nitrates
Inorganic compounds which dilate blood vessels, reducing blood pressure and increasing blood flow to muscles
54
3 benefits and risks of nitrates
+ reduced blood pressure +increased blood flow +increased intensity of performance -headaches -long term health affects unclear -dizziness
