Villanueva, Natalie
Cardiorespiratory responses can be evaluated by measuring the workload, heart rate (HR), blood pressure (BP), and rate of perceived exertion (RPE) in a submaximal test. Although it is often used to determine an exercise prescription, it also evaluates the aerobic fitness of an individual. There are many aerobic activities that benefit health/fitness. Swimming has been one of most popular fitness activities. Swimming is a non-weight bearing exercise that allows individuals who have joint problems or arthritis to exercise. Although, swimming has been ranked second to walking, dancing has become increasingly popular. Zumba is a weight bearing exercise that consists of different types of dance styles such as salsa and rumba.

2015-01-01T00:00:00ZA Comparison of Continuous and Intermittent Exercise Effect on Excess Post-Exercise Oxygen Consumption (EPOC)Tran, Kellyhttp://hdl.handle.net/10106/266122023-06-26T15:28:08Z2015-01-01T00:00:00ZA Comparison of Continuous and Intermittent Exercise Effect on Excess Post-Exercise Oxygen Consumption (EPOC)
Tran, Kelly
INTRODUCTION: As individuals conduct exercise, the body’s oxygen consumption rate is elevated to provide the increase oxygen demanded by the working muscles. During recovery, oxygen consumption declines but remains elevated above pre-exercising resting levels. The length of time that oxygen consumption remains elevated is dependent on the intensity and duration of the exercise, as well as the fitness level of the individual. The oxygen that is consumed above resting levels during recovery is referred to as excess post-exercise oxygen consumption (EPOC).
PURPOSE:The purpose of this study is to determine if there is a difference in excess post-exercise oxygen consumption between continuousand intermittent exercise.
METHODS: Five men (M: age 23.4 ±3.71) from the University of Texas at Arlington, volunteered to participate in this study. Each participant’s height and weight were measured and recorded. Participants came in for two separate testing sessions (continuous and intermittent). Each protocol was randomly assigned to each participant. During continuous protocol, participants cycled on a monark cycle ergometer for twenty minutes. For intermittent protocol, participants cycled in ten minute intervals. Participants performed both tests at 70 percent of their age predicted heart rate max. While conducting the test, oxygen consumption (VO2) was measured by the metabolic cart.
RESULTS: The EPOC that was calculated for continuous exercise was 0.29 ±0.071 L/min and for intermittent the EPOC was 0.36 ±0.18 L/min there was no significant difference (p > 0.05). The total net VO2for continuous exercise was calculated to be 1.43 ±0.36 L/min and the intermittent values were 1.79 ±0.88 L/min; there was no significant difference (p > 0.05). The time it took for the participants to recover after continuous protocol was 4.8 ±1.79 minutes. For intermittent exercise, the recovery time was 5.2 ±0.84 minutes; there was no significant difference in recovery time (p > 0.05). The average heart rate during recovery for continuous exercise was 111.84 ±6.26 bt/min, while the average heart rate during recovery for intermittent exercise was 112 ±5.14 bt/min. There was no significant difference in average recovery heart rate (p > 0.05).
CONCLUSION: The results of this study indicate that there is no difference between continuous and intermittent exercise and its effect on EPOC. Future research should be conducted to determine the role that intensity has on EPOC.

2015-01-01T00:00:00ZImpact of Diminished Visual Feedback on Postural ControlThomas, Kripahttp://hdl.handle.net/10106/266112023-06-26T15:29:24Z2015-01-01T00:00:00ZImpact of Diminished Visual Feedback on Postural Control
Thomas, Kripa
INTRODUCTION: Sensory systems are an integral key to efficient postural control. Out of all the sensory systems, visual has shown to be the most heavily relied on. With the progression of age there is a decline with not only this sensory system but also postural control. The vestibular sensory system contributes to equilibrium, balance, and spatial orientation.
PURPOSE: The purpose of this study was to evaluate postural control when visual feedback was diminished in an unstable support surface.
METHODS: Twelve women (age 75 +10.0 yrs), of the Center of Healthy Living and Longevity, volunteered to participate in this study. Each subject participated in a 12 week balance/strength training program to increase balance. A pretest was given to them before the program started and a post test after the last session. The tests before and after included a Sensory Organization Test on the Neurocom (The SMART Balance Master®). The condition of eyes closed with an unstable support surface was analyzed after three trials and an average of the scores were taken for comparison.
RESULTS: The hypothesis was not supported. After analyzing the data with a dependent sample t-test, post testing equilibrium scores (M = 70.70, SD= 7.53) did not yield a significantly greater mean score than pre testing equilibrium scores (M = 67.52, SD= 10.82) t (11) = -1.22, p= .25.
CONCLUSION: Although there was an increase in vestibular function during post testing; the results of this study indicate that balance/strength training does not aid in a significant difference for vestibular function in regards to postural control.

2015-01-01T00:00:00ZEffects of C4 on Maximum Testing During Bruce ProtocolPatel, Darshanhttp://hdl.handle.net/10106/266102023-06-26T19:58:31Z2015-01-01T00:00:00ZEffects of C4 on Maximum Testing During Bruce Protocol
Patel, Darshan
INTRODUCTION: The Bruce Protocol is a commonly used test for determining maximal oxygen consumption (VO2max). The VO2maxvalue is a measure of an athlete’s aerobic endurance. VO2maxcan be reported in absolute terms (L/min) or it can be reported in relative terms (ml/kg/min). C4 is one of the most popular pre-workout supplements on the market. Research has showed that C4 can improve an athletes’ anaerobic power and endurance, but not much research has been done on how C4 can affect aerobic endurance.
PURPOSE: The purpose of this study was to evaluate the effects that C4 had on subjects during maximal exercise testing using the Bruce Protocol.
METHODS: Five men (age 23.4 ±3.71 yrs) from UTA volunteered to participate in this study. All five men were active and participated in some type of sport during and through the 6 months prior to this study. Each subject completed the Bruce Protocol, which is a graded exercise test on a treadmill, which increases speed and elevation every 3 minutes until they could not run anymore. Each subjected completed this test twice: once after drinking a placebo and the other after drinking C4. During each test heart rate (HR), rate of perceived exertion (RPE), relative maximal oxygen consumption (mL/kg/min), and time of exercise were all recorded.
RESULTS: The maximum HR for the placebo trial was 191.6 ±9.0 bpm compared to 191.4 ±5.8 bpm with the C4 trial. This difference was not significant (p= 0.14). The average relative VO2maxfor the placebo trial was 42.12 ±6.9 mL/kg/min compared to 44.16 ±6.8 mL/kg/min for the C4 trial which was also not significantly different
(p= 0.43). The average time of exercise for the subjects during the placebo trial was 11 min ±6 sec compared to an average time of 11 min ±8.4 sec on the C4 trial (p= 0.43) which was also not significantly different. Finally, the average RPE for the placebo trial was 17.4 ±1.5 compared to 18.2 ±1.3 on the C4 trial resulted in no significant difference between the two conditions (p= 0.19).
CONCLUSION: The results of this experiment do not support the claims that C4, when consumed prior to exercise, will improve performance. However, this study evaluated maximal exercise only. Further studies are need to determine if C4 will improve performance during submaximal exercise, such as the type generally involved in a “workout.”
