An under active thyroid is not usually serious and is combated through the use of hormone tablets to replace the hormones that the thyroid isnt making (thyroxine). A normal thyroid produces to hormone one called thyroxine (T4) and another called triiodothyronine (T3). In the cells the T4 is converted to T3. Its the T3, derived from the T4 or secreted as T3 from the thyroid gland, which is biologically active and influences the activity of all the cells and tissues of the body. what causes the thyroid to be under active is the fact that not enough thyroxine is produced (hypothyroidism).
The syptoms of hypothyroidism
- being sensitive to cold
- weight gain
- muscle aches and weakness
- muscle cramps
- dry and scaly
- brittle hair and nails
- carpal tunnel syndrome
Anyone with an underactive thyroid should not be dettered from wanting to pursue a life in the fitness industry or prevent it from wanting to achieve that desired body. Sarah has proven this with her hard work and dedication, she has been on top her medication and has kept on top of her calorie controlled diet and exercise. Sarah has learnt how to control it so well she can even enjoy meals out and nights out with her friends.
Sarahs routine has been comprised of taking part in very intermitent exercise such as interval training, circuit training and insanity. With regards to any cardiovascular training the after burn effect has been taken into great consideration, therefore sarah is burning more calories when sedentary. Also, in order to increase sarahs metabolism, more resistance training has been incorporated into her routine. this will increase her lean mass and will therefore increase her fat burning potential when she isn't at the gym.
