Research Investigation on High-Intensity Interval Training (HIIT)

Homework #3
Option 2 Questions
1 What was the purpose of this article? (10pts)
The research investigation aimed to establish the effects outcomes six-week high-intensity interval training (HIIT), moderate-intensity continuous training (MICT), and resistance training (RT) regimens had on upper and lower-limb endothelial functioning among older adults.
2 If other research focused on upper limb blood flow, why did these authors choose to look at lower limbs as well? (5 pts)
The study investigated the flow of blood in the lower limbs because the lower appendage arteries such as popliteal arteries are more susceptible to atherosclerosis and peripheral vascular diseases than upper-limb arteries. Also, they saw a need to establish the difference in the outcomes of exercise training on the functioning of vascular endothelial in lower and upper limb arteries.
3 Define and explain the following (2 pts each):
1 Endothelial tissue refers to cells found in blood vessels that determine the overall health of the blood vessels.
2 FMD- it is the determination of the endothelium’s capability to make and let out nitric oxide once reactive hyperemia occurs due to past distal ischemia.
3 POP-popliteal arteries are arteries found in lower limbs, which are highly likely to endure atherosclerosis and peripheral vascular ailments.
4 L-FMC- it is the reduction in diameter of conduit arteries due to a distal ischemic episode.
5 HIIT-it is a form of exercising that combines intense exercises with low-intensity periods of recovery.
6 MICT- it is a form of exercising that incorporates moderate-intensity workouts for an extended period.
4 When the authors discuss how “L-FMC and reduced shear stress influences vascular tone…” what does this mean? (may need to review Ex Phys, Cardiopulmonary, Clinical to investigate) (10 pts)
The authors meant that the two affect the oxidation reaction process of the vascular wall by controlling the occurrence of various oxidase systems such as thrombosis and inflammation of vessel walls, leading to different patterns of responses.
5 Describe who the participants were? (10 pts)
The article’s subjects were thirty-eight women aged fifty-six to eighty-three years old sampled from Acadia University’s Active Aging program. The ladies were characterized by a resting blood pressure of 140/90 and the absence of physical issues that would deem exercising a problem. Out of the 38 ladies, three were under medication for hypothyroidism, four were under high blood pressure medication, and another had asthma.
6 Explain IN DETAIL the three different exercise protocols used during the ...
