The Effect of Exercise on the Specific Metabolic Rate of a Procambarus sp.
Lizzie Sweyer
1 Abstract The objective of this study was to find out the effects of exercise on the specific metabolic rate of three different Pocambarus sp., a species of crayfish. During metabolism, oxygen or O2 plays a big role in receiving electrons at the end of an electron transport chain. These electrons are then transported down the chain where they give off energy to convert low-energy ADP to high-energy ATP. By increasing the need of oxygen as well as the usage of energy in the Pocambarus sp., it would result in the uptake of O2 to increase. Due to this, we hypothesized that when there is an increase in exercise, O2 levels would rise and directly increase the specific metabolic rate of the Pocambarus sp. This hypothesis was used on three different Pocambarus sp., all

The specific metabolic rate of the exercised metabolic rate in crayfish one was 0.0229 O2*g-1*min-1, in crayfish two was 0.0164 O2*g-1*min-1, in crayfish three was 0.0155 O2*g-1*min-1. The mean metabolic rate of the three non-exercised Procambarus s. in room temperature water over the 20 minutes of experimentation was 0.01608 +/- 0.0025 O2*g-1*min-1 while the three exercised Procambarus s. in room temperature water over the 20 minutes of experimentation was 0.0182 +/- 0.0040 O2*g-1*min-1. The general trend of crayfish 1 was the non-exercised metabolic rate was lower than the exercised metabolic rate, while in crayfish 2 the non-exercised metabolic rate was higher than the exercised metabolic rate and in crayfish 3 the non-exercised metabolic rate was barely higher than the exercised metabolic rate (Figure 1). The paired, one-tail t-test that compared metabolic rate from exercise and non-exercised yielded a p-value of
