The Effect Of Ankle And Hallux Positioning On Hallux Force Production, Mickelle Maccabe, Tanner Krupp, Joshua Sponbeck, Wayne Johnson, Dustin Bruening
International Journal of Exercise Science: Conference Proceedings
The foot is not simply a rigid lever, but contributes substantially to movement energetics, primarily through muscle-tendon dynamics. However, more research is needed to understand how the small muscles of the foot generate and regulate force production. PURPOSE: We quantified the effects of ankle and hallux positioning on hallux flexion force production, isolating the contribution of the flexor hallucis longus (FHL) and brevis (FHB). We hypothesized the FHL length changes would influence hallux force. METHODS: Eighteen healthy adult volunteers participated with written consent. Participants assumed each of four testing positions on a custom-built isometric toe flexion force sensor: ankle …

Neutrophil- And Myeloid-Derived Suppressor Cell-Conditioned Medias Cause Myotube Atrophy And Alter The Myotube Transcriptome, Heidi Disbrow, Jonathan Specht, Michael Deyhle
International Journal of Exercise Science: Conference Proceedings
Cancer-related inflammation and altered hematopoiesis leads to increased neutrophil and myeloid-derived suppressor cell (MDSC) production and reduced lymphoid and erythroid cell production. Recently, we found cells bearing a surface antigen belonging to both MDSCs and neutrophils accumulate in skeletal muscle and contribute to atrophy that occurs in cancer cachexia. It is unknown if these cells cause skeletal muscle atrophy directly, or if MDSCs and neutrophils impact atrophy differently. The PURPOSE of this study was to explore the direct effects of neutrophil- and MDSC-conditioned media relative to control medium on myotube atrophy and transcriptome.METHODS: Neutrophils were isolated from the …
Changes Of Achilles Tendon Size Across Different Running Races: A Preliminary Study, Summer S. Hollifield, Joshua Sponbeck, Lee J Hinkle, Alyson Radford, Camille Nguyen, Aaron W. Johnson
Changes Of Achilles Tendon Size Across Different Running Races: A Preliminary Study, Summer S. Hollifield, Joshua Sponbeck, Lee J Hinkle, Alyson Radford, Camille Nguyen, Aaron W. Johnson
International Journal of Exercise Science: Conference Proceedings
A common form of physical activity is running. However, a large percentage of runners will injure a lower extremity tendon. Ultrasound imaging provides useful insight on tendon health and prevalence of structural changes. Previous research in younger adults has shown the Achilles tendon (AT) thins over the course of a distance run. This suggests that tendon structure may become altered based on the distance and surface of the course. Research studies have also found that a greater than 20% increase in AT thickness from the proximal calcaneous to the thickest portion of the tendon is associated with tendinopathy. PURPOSE: To …

International Journal of Exercise Science: Conference Proceedings
Non-local fatigue occurs when one muscle group causes the fatigue of a different muscle group within a training session. This phenomenon may be explained by an increase in deoxygenated hemoglobin due to the competition of oxygenated blood between muscle groups. PURPOSE: Therefore the purpose of the study was to determine if adding upper body exercises to a lower body workout results in a significant difference in vastus lateralis deoxygenated hemoglobin values compared to lower body only. METHODS: One lower-body workout (LB) consisted of five sets of leg extension (quadriceps only exercise) at 90% of their maximum strength with …

International Journal of Exercise Science: Conference Proceedings
Although a single session of low to moderate intensity exercise induces post-exercise hypotension (PEH), the effect of blood flow restriction (BFR) exercise on PEH is still unknown. PURPOSE: We tested hypothesis that aerobic exercise with BFR induced (PEH), and the reduction in blood pressure (BP) was due to peripheral vasodilation via the histamine receptors. METHODS: Ten male subjects participated in this study. The subjects were randomly assigned to walk on the treadmill for 10 minutes at 6.4 k/m, 0% grade with or without BFR after taking histamine receptor blockade. Following exercise, BP was measured at 10 min interval for 60 …
Are Responses To Submaximal Exercise Less Reproducible In Females Vs Males Due To The Menstrual Cycle?, Grace Loveless, Hadley Peay, Jayson Gifford, Jessica Linde
Are Responses To Submaximal Exercise Less Reproducible In Females Vs Males Due To The Menstrual Cycle?, Grace Loveless, Hadley Peay, Jayson Gifford, Jessica Linde
International Journal of Exercise Science: Conference Proceedings
Exercise-science research often excludes young eumenorrheic females due to the presence of a menstrual cycle (MC) and lack of knowledge on how much variability the MC adds to the physiological responses to exercise. PURPOSE: To determine if the metabolic response to submaximal exercise is less reproducible in females with a menstrual cycle compared to males. We hypothesized females would exhibit greater variability in the metabolic response to submaximal-intensity exercise across the MC than males across a similar timespan. METHODS: Eumenorrheic, endurance-trained females (n=10, age=24.1 ± 5.59) performed two 5-minute bouts of constant-load, moderate-intensity cycling at three time points across the …

International Journal of Exercise Science: Conference Proceedings
Hiking is a popular form of recreation with over 57 million participants in the U.S. Many of those hikers also use smart-watches to track their steps, distance and other variables. Anecdotally, the use of trekking poles appears to reduce the accuracy of these smart-watch measures, most notably step counts. PURPOSE: To determine if differences were observed in step counts when hiking with or without trekking poles. METHODS: 10 recreationally active adults (n=5 males, n=5 females, aged 20-39 yrs) randomly completed three trekking pole hiking conditions (no poles, 1 pole, or 2 poles) of ~10 min. uphill and ~10 min. downhill …
Body Mass & Muscle Weight Following Volumetric Muscle Loss Injuries, Kyndal Jones, Jj Payne, Matt Mangus, Jake Sorensen
Body Mass & Muscle Weight Following Volumetric Muscle Loss Injuries, Kyndal Jones, Jj Payne, Matt Mangus, Jake Sorensen
International Journal of Exercise Science: Conference Proceedings
Volumetric muscle loss (VML) is the traumatic or surgical loss of a significant amount of skeletal muscle, resulting in decreased function and regenerative abilities. Despite the decrease in function, when one muscle is injured or removed, there is typically a compensatory response in the surrounding muscles that promote hypertrophic adaptations. PURPOSE: The purpose of this study was to observe how surgery impacts body mass and the weight of certain muscle groups 6 weeks after a VML injury to the tibialis anterior (TA) muscle, with particular interest in determining if a hypertrophy response occurs in surrounding muscle groups. METHODS: …

Effect Of Barefoot Strength Training On Time To Stabilization And Ankle Inversion During Single-Leg Drop Landing In Ncaa Division I Female Volleyball Players, Logan Manley, Sydney Leisz, Trevor Gillum, William Boyer, Jared Coburn
International Journal of Exercise Science: Conference Proceedings
When volleyball players land from a jump, there is a large energy transfer that occurs throughout the kinetic chain. Time to stabilization (TTS) is a measure that represents the ability to control ground reaction forces (GRF) upon landing. Ankle inversion (INV) angles upon landing also represent the risk of ankle injury due to forceful inversion of the ankle joint. Prior research has found differing risk for injury when accounting for volleyball sport-specific limb dominance and inter-limb asymmetries. A joint is weakened when exposed to repetitive landing movements, putting it at a higher risk of injury due to continual absorption of …

The serve penetration test has been used in tennis to assess the approximate skill level of a player. While similar to tennis, pickleball is less studied. We adapted the serve penetration test to the pickleball court. PURPOSE: The purpose of the study was to assess interposition reliability, interrater reliability, and intertarget reliability of the adapted pickleball serve penetration test. METHODS: For the pickleball serve penetration test, there were four different targets that the subject aimed for, located on the left and right corners, as well as the left and right middle of the court. Each target had four …

Running is one of the most common forms of exercise. Tendinopathy is among the most prevalent injuries found among runners. Ultrasound imaging of tendinopathy presents as an enlargement of the tendon with a decrease in echo intensity. Previous research has found that aging leads to an increased susceptibility to tendinopathy. PURPOSE: This study aimed to determine how the effects of aging will impact the structural change of the Achilles tendon (AT) before and after long distance running. METHODS: 27 senior runners (age: 70.9±9.8 yrs; Female=15 Male=12) ran 5k or 10k distances at the Huntsman World Senior Games. Each …
