It is a BC when its hot you dihyrate more than usual
Answer:
b. Karvonen formula
Explanation:
The question ask us to select one so i'm going to stick with the Karvonen Formula. The Karvonen Formula is also known as the Heart Rate Reserve (HRR).
Karvonen Formula emphasize on the quest of looking for the Heart Rate Reserve (Target Heart Rate) by the complex interplay between the combination of finding the Resting Heart Rate and the Maximum Heart Rate. The resting heart rate is said to be potential (i.e to be at rest).
The aim of employing the Karvonen Formula (Heart Rate Reserve Method) is to find out the training intensity based on the difference between someone’s predicted maximal heart rate (MHR) and resting heart rate (RHR).
∴ The Karvonen Formula is given as:
HHR =[(HR max- HR Min) x desired intensity] + HR Rest.
Is there any other part to the question? I feel like something’s missing?
Answer:
a. internal
Explanation:
This experiment results show that the drug effect on patients was effective improving their immune functioning so external validation would be sufficient for this study.
Statistical information shows that the difference between the treatment group and the control group wasn't significant but still shows the improvement on immune system and effectiveness in Jeremy's test.
The drug improved the participants immune functioning as it claimed it would so costruct validation would be sufficient.
We cannot be sure that the drug stablishes a trustworthy cause and effect relation between treatment and outcome on patients and alternative explanations can be found since there was an improvement on the control group immune system as well.
Internal validation requires a trustworthy cause and effect relationship between treatment and outcome stablished by the experiment so it isn't sufficient for this study.
