Fun versus Practical: Physiological Responses and Preference of Exercise Equipment

The elliptical cross trainer has become a popular a mode of exercise, but can only be used indoors. The StreetStrider was designed as an outdoor elliptical-bike. PURPOSE: The purpose of this study is to determine whether the elliptical or the StreetStrider was more enjoyable, and to compare the physiological variables for energy expenditure, heart rate (HR), VO2, and Rate of Perceived Exertion (RPE). METHODS: Thirty participants (15 male, 15 female, mean age=22±2) from Cleveland State University exercised for 20 minutes at 75% of their age predicted maximal heart rate on the StreetStrider and elliptical. Energy expenditure was measured with a COSMED K4b metabolic system. Participants’ RPE was recorded every five minutes using the Borg Scale for Rate of Perceived Exertion. Data was analyzed using SPSS version 18. A paired sample t-test compared physiological responses. A one-way ANOVA analyzed gender differences. A significance level of .05 was used to determine significance. RESULTS: No significant differences were shown in energy expenditure (p=.930), HR (p=.098), or in average RPE (p=.529) between the exercise trials. A preference survey concluded that most subjects found the StreetStrider more enjoyable than the elliptical. CONCLUSION: The StreetStrider is more enjoyable than the elliptical and as effective in energy expenditure, and could serve as a substitute for the elliptical.https://engagedscholarship.csuohio.edu/u_poster_2014/1034/thumbnail.jp

Comparison of Electronic and Mechanical Handgrip Devices in Lowering Blood Pressure

Hypertension causes billions of deaths per year (Millar et al., 2013). The Zona PlusTM is an expensive tool designed to lower blood pressure (BP) using isometric exercise. This exercise may be achieved using a less expensive Handgrip Dynamometer. PURPOSE: The purpose of this research is to determine if the Zona or Handgrip Dynamometer is more efficient at lowering BP and most cost effective for patients. METHODS: Twenty subjects used the Zona and twenty subjects used the dynamometer three times per week for six weeks. BP was taken once per week prior to the treatment. A maximum voluntary contraction (MVC) was recorded for each hand before every treatment. Participants were required to hold the handgrip at 30% of their MVC for four two-minute contractions. A paired samples T test was used to analyze changes in participants’ BP. A one-way ANOVA was used to compare the BP changes between the Zona and the Handgrip. RESULTS: The results indicated no significant changes in participants’ pre- and post- treatment after training when using the Zona for either stolic (p=0.225) or diastolic BP (p=1.000). There was also no significant difference in participants’ post treatment systolic BP (p=0.199), however, the post treatment for diastolic increased significantly (p=0.027 BP between those that used the Zona PlusTM and Handgrip Dynamometer. CONCLUSION: Though the Dynamometer is more cost efficient, neither the Zona nor the Dynamometer resulted in lowered BP.https://engagedscholarship.csuohio.edu/u_poster_2014/1037/thumbnail.jp

Physiological responses and exercise preference between the Trikke and the bicycle ergometer

Background/Objective: The positive relationship between health benefits or the wellbeing of individuals and their engagement in physical activity is well-documented. Nevertheless, many Americans show no interest or perceive that “exercise is boring” as one of the reasons for not exercising. For these reasons, it is important to promote fun and enjoyment aspects of the activity to motivate people to participate in physical activity. The purpose of this study was to examine the physiological responses and the perception of enjoyment between the Trikke and the bicycle ergometer. Methods: Thirty college students (15 males and 15 females) aged 18–45 years old voluntarily participated in the study and showed up on three occasions. The first session involved a 5-minute instructional video and practice on the Trikke. Participants were then randomized into sessions which involved either riding the Trikke or the bicycle ergometer. Participants of each group performed a 20-minute ride at 75–80% of maximal predicted heart rate. Results: Results of mixed design analysis of variance (ANOVAs) indicated that VO2, energy expenditure, and rate of perceived exertion (RPE) of the participants were significantly (p < 0.001) higher when using the bicycle ergometer than the Trikke, and female participants were able to manipulate the Trikke more efficiently than their male counterparts. Conclusion: Participants were more efficient in using the Trikke than the bicycle ergometer. The Trikke may be an enjoyable alternative for those individuals, particularly women, who have lost interest in traditional forms of exercise
