uses of hormones in life Flashcards
1
Q
growth hormone
A
- abuse in sports
- more difficult to detect
- enhances physical performance (not true, however believed)
2
Q
anabolic steroids
A
- illegal, banned
- hormones from males and females
- muscles bigger, recover quicker, reduces muscle damage from training, increased aggressiveness
3
Q
testosterone and androgenic anabolic steroids
A
- AAS’s, derived from male hormone testosterone
- increase protein synthesis
- prominent breasts, balding (men)
- deeper voice, enlarged clitoris, increased body hair, baldness and infrequent or absent periods (women)
- severe acne, liver abnormalities, tumours, increased risk for tendinitis and tendon rupture
- high blood pressure (hypertension), heart and circulatory problems, aggressive behaviours, psychiatric disorders (depression), inhibited growth and development in teenagers
4
Q
female hormones
A
- after pregnancy women are stronger from hormones
- oral contraceptives are permitted and desired, reduce menstrual loss and subsequent less iron deficiency, also menstruation is more tolerable and can be adjusted to avoid the competitions dates
5
Q
EPO
A
- naturally occurring produced by kidney to regulate red blood cell formation
- introduction increases red blood cell production
- increase in endurance
- not easy to detect and lasts for 24 hours
- dangerous because it ‘thickens’ the blood and can cause clots, stokes or heart attacks
6
Q
hCG and LH
A
- human chorionic gonadotrophin
- Luteinising hormone
- increases production of testosterone
7
Q
insulin
A
- works with GH (growth hormone) to control blood glucose
8
Q
adrenalin
A
- increases heart rate
- force of muscle contractions and respiration
- stimulates nervous system
- body begins to sweat (cool down) and pupils dilate to increase awareness of surroundings
9
Q
cortisol
A
- increase glucose levels, increasing energy levels
- temporarily inhibits other systems, digestion, growth, and immune (saving energy for activity)
- catabolic effect on muscle tissue (breakdown), they are able to recover if the body is at rest
- over-train cortisol levels become chronically elevated
- performance will be negatively affected if muscles can not recover
10
Q
stress system
A
- adrenaline and cortisol
- adrenalin will work first to get our body ready
- cortisol is then released to maintain a time of action
- adrenalin will be more but the cortisol lasts longer and build over periods of time
- weakened activity of immune system, can become ill
- reduced bone formation (can lead to long term osteoporosis - progressive bone disease)
- reduced production of protein
- reduced ability to remember information that had been stored
