The Relationship Between Linear And Nonlinear Analysis On Activity Data, Katlyn J. Nimtz 2018 University of Nebraska at Omaha

The Relationship Between Linear And Nonlinear Analysis On Activity Data, Katlyn J. Nimtz

Student Research and Creative Activity Fair

Activity monitoring in older adults is a great way to predict disability without interfering in their daily life. We can analyze that data using linear and nonlinear analysis. While linear analysis measures the variation of activity during a specific period of time (i.e., mean, standard deviation), nonlinear analysis focuses on the evolution of activity over a period of time. Therefore, the purpose of this study was to observe the relationship between linear and nonlinear analysis of activity data obtained by activity monitoring in older adults. Eight participants wore an activity monitor around their waist for seven days. Linear analysis ...


A Novel Task To Decrease Step Width Variability In Older Adults, Andreas Skiadopoulos, Katherine Allen, Nicholas Stergiou 2018 University of Nebraska at Omaha

A Novel Task To Decrease Step Width Variability In Older Adults, Andreas Skiadopoulos, Katherine Allen, Nicholas Stergiou

Student Research and Creative Activity Fair

Walking is the most common fall-related activity among older adults. Also, older adults experience greater step width variability when walking. Importantly, increased step width variability during walking has been found to be a strong predictor of fall risk and incidence. Therefore, an intervention for reducing increased step width variability may consequently reduce fall risk for older adults. In the present study, we proposed that lateral stepping training program improve walking in older adults by reducing the increased step width variability to normal values. Therefore, the purpose of the present study is to determine the effect of a six-week lateral stepping ...

Department of Biomechanics, University of Nebraska at Omaha, Omaha, NE 68182

With findings that the 6MWT is more efficient than the original 12-minute walk test (12MWT), perhaps it can be evident that even the 6MWT can be shortened to examine its effects in a shorter duration that can be more beneficial to the participant. The objective of this study is to examine the outcomes of each minute throughout the 6MWT trials and to see if functional measures can be ...

Examination Of Resistance Settings Based On Body Weight For The 3-Minute All-Out Critical Power Test, Marlene J. Schulte, Jody L. Clasey, Bradley S. Fleenor, Haley C. Bergstrom

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 585-597, 2018. There are conflicting suggestions regarding the most valid resistance (3-5% of body weight) to use for the critical power (CP) 3-min all-out (CP3min) test to estimate CP and anaerobic work capacity (AWC). The purpose of this study was to determine if the CP and AWC estimates from the CP3min test were affected by the percentage of body weight used to set the resistance on a Monark cycle ergometer. Ten recreationally trained participants (mean ± SD: Age: 22.2 ± 2.2 yrs.) completed the CP3min test at resistances of 4 ...

Behavior Change Techniques And Physical Activity Using The Fitbit Flex®, Emily E. Dunn, Jennifer Robertson-Wilson

International Journal of Exercise Science

International Journal of Exercise Science 11(7): 561-574, 2018. Due to the availability of low-cost accelerometers, there has been an increase in the adoption of physical activity monitors (e.g., Fitbit®) (14) accompanied by a desire to understand the behavior change techniques (BCTs; 15) present in such monitors. One specific Fitbit® monitor incorporates 20 BCTs (15), but how users experience these BCTs has yet to be explored. The purpose of this study was to explore user’s experience with the Fitbit Flex® regarding physical activity behavior and BCTs. The specific research objectives were to: 1) describe Fitbit Flex® users and ...

Validation Of Piezorx Pedometer Derived Sedentary Time, Katelynn Donahoe, Dany Macdonald, Mark Tremblay, Travis Saunders

International Journal of Exercise Science

International Journal of Exercise Science 11(7): 552-560, 2018. Although pedometers are valid tools for measuring physical activity, to date they have not been used to assess sedentary time. The primary purpose of this study was to determine if the PiezoRx pedometer is a valid and reliable measure of sedentary time compared to the hip-worn Actical accelerometer. A secondary purpose was to compare sedentary time derived via the Fitbit Flex with that of the Actical. Finally, a third purpose was to compare sedentary time derived from the above devices, with that of the ActivPAL inclinometer. Thirty-five participants ages 11-69 years ...

International Journal of Exercise Science

International Journal of Exercise Science 11(7): 526-532, 2018. Since its debut in July 2016, Pokémon GO has been a wildly popular mobile gaming app. In contrast to many previous apps, Pokémon GO requires the user to be physically active. However, the extent to which Pokémon GO contributes to physical activity is unknown. Therefore, the purpose of this study was to investigate the physical activity profile of playing Pokémon GO for 60 minutes in recreationally active college students. College students (n=27, n=19 female) were fitted with an accelerometer, pedometer, and heart rate monitor to assess the activity demands ...

A Real-Time Wireless Sweat Rate Measurement System For Physical Activity Monitoring, Andrew Brueck, Tashfin Iftekhar, Alicja B. Stannard, Kumar Yelamarthi, Tolga Kaya 2018 Central Michigan University

A Real-Time Wireless Sweat Rate Measurement System For Physical Activity Monitoring, Andrew Brueck, Tashfin Iftekhar, Alicja B. Stannard, Kumar Yelamarthi, Tolga Kaya

Alicja Stannard

There has been significant research on the physiology of sweat in the past decade, with one of the main interests being the development of a real-time hydration monitor that utilizes sweat. The contents of sweat have been known for decades; sweat provides significant information on the physiological condition of the human body. However, it is important to know the sweat rate as well, as sweat rate alters the concentration of the sweat constituents, and ultimately affects the accuracy of hydration detection. Towards this goal, a calorimetric based flow-rate detection system was built and tested to determine sweat rate in real ...

International Journal of Exercise Science 11(3): 468-478, 2018. The purpose of the current study was to determine changes in balance and strength following an eccentric resistance training program in community-dwelling older adults who reported no history of falling. Participants (N = 14, 8 female, 6 male; age = 63.5 ± 2.0 years) completed an 8-week eccentric exercise training intervention on a commercially available eccentric step machine. Training included 2 training sessions per week, with a duration of 5 to 10 minutes and an intensity of 30 to 50% maximal eccentric strength. Single leg stance, 30-second repeated chair stand, timed up-and-go ...

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 479-492, 2018. The purpose was to determine if pull-up performance was affected by the use of chalk (100% magnesium carbonate) during open-handed and pinch grip weight-assisted pull-ups (WAPU) in recreationally-trained rock climbers. Furthermore, the reliability of open-handed and pinch grip WAPU was also investigated. Recreationally-active volunteers (n = 9) completed six counterbalanced trials. Participants used chalk during four trials to determine the reliability (test-retest) of the open-handed and pinch grips. While two of the six trials were used to determine if open-handed and pinch grip WAPU performance was affected without using chalk. Three of ...

International Journal of Exercise Science

International Journal of Exercise Science 11(6): 462-467, 2018. Mild traumatic brain injuries (mTBIs) are common in contact sports. There is an association between mTBIs and altered motor function. BioSway technology measures individuals’ balance using the Balance Error Scoring System (BESS). Prior to incorporating BESS testing in concussion protocol, other variables that influence the BESS test require review. The objective of this study is to determine if game fatigue in hockey players also influences the BESS score. 23 male (21.08 ± 1.09) National Collegiate Athletic Association (NCAA) athletes were tested using the BioSway™ (Biodex, USA). The BESS test measures ...
