Blood Flow Restriction As A Potential Therapy To Restore Physical Function Following Covid-19 Infection, Isaac J. Wedig, John J. Durocher, John Mcdaniel, Steve Elmer
Blood Flow Restriction As A Potential Therapy To Restore Physical Function Following Covid-19 Infection, Isaac J. Wedig, John J. Durocher, John Mcdaniel, Steve Elmer
Michigan Tech Publications, Part 2
Accumulating evidence indicates that some COVID-19 survivors display reduced muscle mass, muscle strength, and aerobic capacity, which contribute to impairments in physical function that can persist for months after the acute phase of illness. Accordingly, strategies to restore muscle mass, muscle strength, and aerobic capacity following infection are critical to mitigate the long-term consequences of COVID-19. Blood flow restriction (BFR), which involves the application of mechanical compression to the limbs, presents a promising therapy that could be utilized throughout different phases of COVID-19 illness. Specifically, we hypothesize that: 1) use of passive BFR modalities can mitigate losses of muscle mass …

This study aimed to model adolescents’ cardiorespiratory fitness performance change trajectories longitudinally across high school years and its relation to school- and individual/student-level factors. We employed hierarchical linear modeling to examine longitudinal cardiorespiratory fitness performance changes, as measured by the progressive aerobic capacity endurance run (PACER), over the years, between sexes, and in association with the school-level variables. Participants were 76,227 adolescents from 80 high schools in the mid-Atlantic region of the United States. School-level academic performance (SAP), the percent of students eligible for free and reduced-price meals (FARM), and physical education student-faculty ratio were obtained with permission from the …
Validation Of A Novel Vo2max Protocol, Griffin Green
Validation Of A Novel Vo2max Protocol, Griffin Green
Masters Theses & Specialist Projects
Though there are several to choose from, the Bruce protocol is the most commonly utilized treadmill protocol when assessing maximal oxygen consumption (VO2max). Originally developed for cardiac patients, the Bruce protocol may not be an appropriate treadmill protocol for young or trained individuals with higher levels of cardiorespiratory fitness. The steep grade used often leads localized muscular fatigue, which may cause participants to end the test prior to reaching their true VO2max. Another popular protocol, the Astrand, also utilizes a steep grade, but the speed remains constant. Similar to the Bruce, the Astrand protocol may not prompt a maximal cardiovascular …
The Difference In Aerobic Capacity And Anaerobic Power Between Young Male Recreational Basketball And Soccer Players, Lesley Ngo
Kinesiology Student Research
Basketball and Soccer are two sports that are usually played recreationally that provide for an active lifestyle. At competitive levels of both sports athletes undergo different kinds of training in order to improve performance for longer periods of time but not recreationally. Basketball and soccer are sports which often require the use of both anaerobic and aerobic faculties of energy production in activities including but not limited to: dribbling, sprinting, passing, shooting, walking and jumping. The purpose of this research was to investigate the difference in aerobic capacity and anaerobic power between young male recreational basketball and soccer players. It …

Are You More Fit Than A Third Grader?, Stevie Carpenter, Taylor Elrod, Jesse Gruber, Danny Sayavong
Kinesiology Student Research
Previous studies have tested why adults seem to perform better in the areas of aerobic and anaerobic capacity, they have found that this occurs because with age comes a higher lung capacity. Also previous studies have looked at the comparison between motor development and its effect on fitness level. It was found that the higher an individuals motor proficiency the higher their fitness level appeared.
Aerobic Capacity Of Wheelchair Basketball Players During Arm Crank Ergometry Vs Treadmill, Steve Quaker
Aerobic Capacity Of Wheelchair Basketball Players During Arm Crank Ergometry Vs Treadmill, Steve Quaker
Kinesiology Student Research
It is difficult to determine the aerobic capacity of wheelchair athletes by the accepted standards and methods of testing. The levels of disability and the associated functionality of the individual as well as wheelchair design itself impacts the measure of VO2 peak. VO2 peak is the maximum volume of O2 that a person's body can transport to tissue during incremental exercise. At the current time VO2 peak is the best indicator of physical fitness of an individual.

Objective- Individuals with diabetic autonomic neuropathy (DAN) exhibit an increased resting heart rate but depressed maximal heart rate. Thus, the purpose of this study was to examine the validity of using either percent of heart rate reserve (HRR) or a rating of perceived exertion (RPE) scale to prescribe exercise intensity in diabetic individuals both with and without DAN.
Research Design and Methods-The subjects consisted of 23 individuals with type 2 diabetes, ages 45-75 years, with (DAN; n=13) or without (No DAN; n=10) clinical signs of DAN, as assessed by heart rate variability using the expiration-to-inspiration ratio of the …
Vo2 Reserve And The Minimal Intensity For Improving Cardiorespiratory Fitness, David P. Swain, Barry A. Franklin
Vo2 Reserve And The Minimal Intensity For Improving Cardiorespiratory Fitness, David P. Swain, Barry A. Franklin
Human Movement Studies & Special Education Faculty Publications
Purpose: The American College of Sports Medicine has stated that aerobic: training needs to occur at a minimum threshold intensity of 50% VO2max for most healthy adults and at 40% VO2max for those with a very low initial fitness. Recently, the concept of VO2 reserve (% VO2R, i.e., a percentage of the difference between maximum and resting VO2 has been introduced for prescribing exercise intensity, This analysis was designed to determine the threshold intensity for improving cardiorespiratory fitness expressed as %VO2R units. Methods: Previous studies in healthy subjects (N = 18) that …

Fine-Tuning The Exercise Formula, David Swain

(First paragraph) One hundred years ago, our forebears consumed more calories than we do today, yet they were leaner. Labor-saving devices were a rarity, and so in everyday life most people worked very hard physically. Obesity was present, of course, but afflicted only a small fraction of the population. We are not as fortunate today.
