1.

Beta blockers slow down the heart rate which can prevent increase in it when you
exercise.less o2 is transported around the body Hence less glucose is broken down to pyruvate
and body goes on increasing anaerobic respiration breaking down glucose to lactate.​(3)

2.injecting a certain area of the ligament can cause the ligaments to weaken. This can lead to
loose joints that bend more than usual. ​(1). Ligaments join bone to bone.

3. They are banned as it makes it impossible for a medical professional to detect any prohibted
substances and their effects as they lose a lot of urine. It can also lead to dehydration and
weight loss which isnt useful during playing the sport ​(2)

4. They will prevent clumping of blood. If if does not work with your blood then your immune
system will produce antibodies against it.​(2)

5. Troponin and tropomyosin ​(2)

6. Actin is the thin filament attached to the Z line on the left. Myosin is thick filament that is right
of the Z line. ​(2)

7. A disease regularly found among particular people or in a certain area.​(0) produced within the
body.

8.Changing the proportion of slow twitch fibres to fast twitch fibres would benefit endurance
athletes in many way. Slow twitch fibres would allow sustained muscle contraction to take place.
Since there are many mitochondria present, it will mainly depend on aerobic respiration for the
production of ATP. greater energy being produced in athletes Muscles with more slow-twitch
fibers have more blood vessels. This is because they need a good and constant supply of blood
and oxygen to let them work for a long time without getting tired.Fast twitch muscle fibres can
produce small amounts of energy very quickly whereas slow twitch muscles can produce large
amounts of energy slowly. There is also less amount of glycogen present​. (4)

9. EPO, by thickening the blood, leads to an increased risk of several deadly diseases, such as
heart disease, stroke, and cerebral or pulmonary embolism. The misuse of recombinant human
EPO may also lead to autoimmune diseases with serious health consequences. ​(2)
