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.
Answer:
Common tests & procedures
X-ray: X-ray of chest is taken to identify the presence of tumor.
CT scan: CT scan of the lungs is performed to identify the location and size of the tumor mass.
Magnetic resonance imaging (MRI): MRI of the lungs can detect the severity and spread of cancer cells.
Positron emission tomography (PET): To observe the function of lungs and its tissues.
Sputum cytology: Sputum tests may be performed in certain cases to look for cancerous cells.
Biopsy: A small sample of the lung tumor cells is obtained to determine if they are cancerous.
It takes about three to six months for most lung cancers to double their size. Therefore, it could take several years for a typical lung cancer to reach a size at which it could be diagnosed on a chest X-ray.
