Effects Of A Strength Training Intervention And Quality Of Life: Case Study On A Sedentary Adult Female, Lucas Frazier
Effects Of A Strength Training Intervention And Quality Of Life: Case Study On A Sedentary Adult Female, Lucas Frazier
Williams Honors College, Honors Research Projects
The purpose of the project is to evaluate physiological and quality of life changes in a
sedentary, senior-aged (55 or older) female using a six-week strength training
intervention. This case study will instruct how to perform a push-pull-legs split
routine by going to the gym three times per week. Prior to the six week intervention,
both quantitative and qualitative variables will be collected to assess baseline data,
including the subject’s resting heart rate, resting blood pressure, grip strength, one-
repetition maximum on seven whole body exercises (dumbbell bicep curl, tricep
pushdown, barbell bench press, wide-grip lat pull-down, seated dumbbell press, …

Background: Left ventricular (LV) torsion is an important indicator of cardiac function that is limited by high inter-test variability (50% of the mean value). We hypothesized that this high inter-test variability is partly due to inconsistent breath-hold positions during serial image acquisitions, which could be significantly improved by using a respiratory navigator for cardiovascular magnetic resonance (CMR) based quantification of LV torsion.
Methods: We assessed respiratory-related variability in measured LV torsion with two distinct experimental protocols. First, 17 volunteers were recruited for CMR with cine displacement encoding with stimulated echoes (DENSE) in which a respiratory navigator was used to measure …
