General Hypothesis: General hypothesis is most general statement that is very likely about the relationship between given variables.

In this situation the general hypothesis is Moderate exercise increases the heart rate.

Null hypothesis: Null hypothesis is the statement which negate any difference or change between two or more variables (phenomenon).

In this situation the Null hypothesis is " there is no difference in the heart rate before and after exercise (µbefore = µafter)".
