Changes In Reproductive Morphology And Physiology Observed In The Amphipod Crustacean, Melita Nitida Smith, Maintained In The Laboratory On Polluted Estuarine Sediments, John T. Tanacredi Ph.D., B. Borowsky, P. Aitken-Ander 2018 Molloy College

Changes In Reproductive Morphology And Physiology Observed In The Amphipod Crustacean, Melita Nitida Smith, Maintained In The Laboratory On Polluted Estuarine Sediments, John T. Tanacredi Ph.D., B. Borowsky, P. Aitken-Ander

Dr. John T. Tanacredi

An earlier study showed that the amphipod crustacean Melita nitida Smith maintained on sediments dosed with waste crankcase oil developed physiological and morphological abnormalities. Most notably, mature females developed abnormal setae along the edges of their brood plates. The present study was conducted to determine whether similar abnormalities might be induced in animals maintained on polluted field sediments containing petroleum by-products among other toxic substances. In the laboratory, heterosexual pairs were maintained on three sediments taken from Jamaica Bay (New York) plus one control sediment and one toxic substratum (Ulva lactuca (L.) thalli). The results mirrored the results of the ...

Behavior Change Techniques And Physical Activity Using The Fitbit Flex®, Emily E. Dunn, Jennifer Robertson-Wilson 2018 Wilfrid Laurier University

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 ...

The Accuracy And Validity Of Ios-Based Heart Rate Apps During Moderate To High Intensity Exercise, Alexa M. Bouts, Lauren Brackman, Elizabeth Martin, Adam M. Subasic, Edward S. Potkanowicz Ph.D.

International Journal of Exercise Science

International Journal of Exercise Science 11(7): 533-540, 2018. People use their smartphones for everything from web browsing to tracking fitness metrics. However, it is unclear whether smartphone-based apps that use photoplethysmography to measure heart rate are an accurate or valid measure of exercise intensity. Purpose was to determine the accuracy and validity of two iOS-based heart rate monitors, Runtastic Heart Rate Monitor and Pulse Tracker PRO by Runtastic (Runtastic) and Instant Heart Rate+: Heart Rate and Pulse Monitor by Azumio (Instant Heart Rate), when compared to the electrocardiogram (ECG) and Polar® T31 uncoded heart rate monitor from moderate to ...

A Descriptive Study Of Objectively Measured Pokémon Go Playtime In College Students, Charles J. Fountaine, Emily J. Springer, Jasmine R. Sward

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 ...

International Journal of Exercise Science

International Journal of Exercise Science 11(7): 516-525, 2018. The purpose of the study was to compare smart apparel (SA) muscle activity measurements to surface electromyography (sEMG) muscle activity measurements during exercise, and determine if any systematic bias of the apparel exists. Thirty-five male participants (Ages 23.1±2.92 yrs, height 178±0.09 cm, mass 81.14±10.59 kg, body fat percentage 15.4±4.79%) provided informed consent for participation. During two separate exercise sessions, participants performed three sets of 12 bodyweight squats and pushups in both SA and sEMG. Conditions (sEMG or SA) were randomly ...

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 ...
