Reema wished to be a participant in the Annual Sports Day. After she took part in athletics for the sports selection, she suffered severe muscular pain. a) Why did Reema get a muscular cramp after running?
b) Which type of respiration took place in her muscle cells while
running? Suggest a way for Reema to overcome her pain.

Hey there mate ;)

According to questions:-

(i) Reema got muscular cramps because excessive anaerobic respiration has taken place. Since she took part in athletics, her legs had to run as fast as possible. which means that her heart beat rate became faster. Therefore, lactic acid along with other substances was formed in her legs.

(ii) During Reema's running, anaerobic respiration took place. In order to relieve her pain, she can do three main steps :-

★ Reema can take a hot shower, which can help her with her tight legs.

★ She also can apply warm towel to increase the flow of blood in her legs again.

★ Or else, Reema can be given a massage, which is the easiest and most accurate option.
