Observational research is a type of evidence in which an investigator watches one or more groups of participants without taking any action. For example, observational research can entail following a group of participants over time to determine which of them will have a particular illness ("Lecture Notes Week 2," 2024). In this scenario, the results will be deduced from the subjects' lifestyle and activity habits. However, when using this method, it might sometimes be unclear how a person's lifestyle contributes to the development of the condition. The second type of evidence is from randomized controlled trials (RCT). RCTs are the best form of experimental scientific research. Their significance in research is that a sample of subjects is drawn from a defined population, for instance sedentary individuals. In such a case, the subjects are then divided into two groups. One group is known as the control group, and it is associated with no interventions taking place. From the identified example of sedentary individuals, the control group would remain sedentary for the duration of the RCT ("Lecture Notes Week 2," 2024). On the other hand, the other group receives the intervention, such as an exercise prescription. At the end of the RCT, evidence from the control and intervention groups is compared, and a decision is made to accept or reject the hypothesis. The third type of evidence is from systematic reviews. They are a type of scien...
