The Acute Effects Of Carrying A Heavy Grocery Bag On Handgrip Rapid Strength In Young And Older Women, Lilly M. Frans, Kayla P. Sisneros, Evan Johnson, Tyler R. Cole, Ty B. Palmer

International Journal of Exercise Science: Conference Proceedings

Declines in handgrip rapid strength characteristics, which include rate of force development (RFD), are commonly reported as a consequence of aging. These declines have been shown to have a detrimental effect on the functional performance abilities of older adults. Such an effect may be amplified by a further decrease in handgrip RFD as a result of fatigue. Evidence suggests that carrying a heavy grocery bag can elicit fatigue-induced changes in muscle activity and cardiovascular parameters. It is unclear if carrying a heavy grocery bag will elicit fatigue-induced changes in handgrip RFD. PURPOSE: The purpose of this study was to …

Driving Entrainment Of Locomotor And Respiratory Systems To Determine Metabolic Efficiency, Michael T. Young, Jennifer M. Yentes, Kuanting Chen Feb 2024

Driving Entrainment Of Locomotor And Respiratory Systems To Determine Metabolic Efficiency, Michael T. Young, Jennifer M. Yentes, Kuanting Chen

International Journal of Exercise Science: Conference Proceedings

Many biological rhythms, including breathing and locomotor rhythms, are interconnected through a phenomenon known as coupling. Locomotor respiratory coupling (LRC) is quantified using a ratio of stride cycles to breaths. For example, an entrained LRC ratio of two strides to one breathing cycle, is a typical ratio humans use while walking. While various ratios have been recorded, previous research has suggested that not deviating from a particular ratio is associated with low energy expenditure. However, recent research challenges the assumption that stronger LRC correlates with lower energy expenditure, but rather, LRC variability is associated with lower energy expenditure. In addition, …

Dehydration may alter the ratio between the extracellular water (ECW) and intracellular water (ICW). Nevertheless, it is unknown whether the ratio between ECW and ICW following resistance exercise (RE) is affected by dehydration. PURPOSE: To determine the effect of dehydration on fluids shift after heavy RE. METHODS: 13 resistance-trained men (age: 21±2years; height: 176.4±6.0cm; weight: 79.5±11.5kg) completed a heavy RE consisting of bilateral leg press and knee extension exercises (5 x 10 at 80% of 1 repetition maximum with 2-mins rest between sets & exercises) either under a hydrated (HS; urine specific gravity [USG] < 1.020) or a dehydrated state (DS; USG ≥ 1.020; 24-hour fluid restriction). The two conditions were separated by two weeks. The ratio of ICW/ECW and total body water (TBW) were measured before (PRE), 1 hour (1H), and 3H after RE using bioelectrical impedance spectroscope (BIS). Additionally, vastus lateralis muscle samples were collected at PRE, 1H, and 3H via muscle biopsy. Muscle samples were weighed (Wt) before (Wet) and after (Dry) heating at 80°C for 55 minutes. For BIS parameters, values were normalized to each participant's HS PRE value. For muscle Wt, percent changes from Dry to Wet were calculated. Repeated measures ANOVAs were used to identify the differences. RESULTS: A significant …

Micronized Biocompatible Ceramic Promotes Muscle Derived Il-6 Release In Disuse, Jacob Kendra, Shadi Golpasandi, Alexandra Naman, Mariam Othman, Joo Kim, Rachel Rauth, Khaled Moustafa, John Lawler, Aaron Morton

International Journal of Exercise Science: Conference Proceedings

Skeletal muscle is remarkably plastic and undergoes significant muscle wasting in response to mechanical unloading. Chronic bedrest and microgravity conditions promote disuse-induced muscle atrophy and dysfunctional myogenesis. While these pathological effects have been well documented, there are currently no effective therapies to remedy this muscle loss. Time-release ion matrices (TRIM) are amorphous non-crystalline biomaterials that promote regenerative gene transcription when injected in soft tissue. However, the detailed pathways involved in TRIM activated regeneration of skeletal muscle are unexplored. Degenerative and regenerative inflammation are key processes in regeneration. PURPOSE: The purpose of this study was to investigate muscle inflammation in response …

Release Of Microrna15a/16 From Skeletal Muscle During Exercise Regulates Proteostasis In Muscle And Cancer, Patrick Ryan, Selina Uranga, James D. Fluckey Feb 2024

Release Of Microrna15a/16 From Skeletal Muscle During Exercise Regulates Proteostasis In Muscle And Cancer, Patrick Ryan, Selina Uranga, James D. Fluckey

International Journal of Exercise Science: Conference Proceedings

Proteostasis, the intricate process of maintaining the proteome, is a critical matter for cellular health. The regulation of the multiple intersecting metabolic pathways comprising the proteostatic network is correspondingly complex and incompletely understood; however, a new and intriguing candidate in understanding this process has emerged in the form of microRNA (miRNA), small RNA species which are capable of regulating hundreds of genes at once by binding to and degrading mRNA transcripts. We have previously shown that muscle contraction results in the release of two miRNA species (miR15a/16) from skeletal muscles, and that a perfusate rich in these miRNAs slows growth …

Effects Of Continuous Aerobic Exercise On Skeletal Muscle Atrophy Induced By Heart Failure, Carolina Tonon, Bertha F. Polegato, Quinten Pigg, Dillon Harris, Aaron Garcia, Daniela S. Inoue, Mariana Janini Gomes

International Journal of Exercise Science: Conference Proceedings

Heart failure is a common and severe disease that worsens morbidity, mortality, and quality of life. One of the clinical manifestations of heart failure is peripheral muscular atrophy, whose presence impacts the prognosis of heart failure patients. Inflammation is one of the main mechanisms related to muscle atrophy. We hypothesized that inflammation, through excessive activation of the Nlrp3 inflammasome, would be tightly associated with skeletal muscle atrophy induced by heart failure. Additionally, aerobic exercise, well known for its anti-inflammatory action, would counteract this condition in a rat model of heart failure. PURPOSE: We aimed to evaluate the effects of continuous …

International Journal of Exercise Science: Conference Proceedings

Body volume (BV) indicates the total 3-dimensional (3D) space an individual occupies. BV is either used alongside body mass in density-based two-compartment models or in conjunction with other body components in multi-compartment models to estimate body composition (BC). BV estimates are typically produced by costly laboratory methods, such as hydrostatic weighing or air-displacement plethysmography (ADP). However, more accessible options are emerging. Smartphone-based 3D scanning uses the phone’s built-in camera to provide a BV estimate in a time-efficient and cost-effective manner. However, few investigations have validated this method against an accepted laboratory technique. PURPOSE: To determine the validity of BV from …

Effects Of Menstrual Cycle Phase On Cold Pressor Test Responses, Zachary R. Oldham, Caitlin P. Jarrard, Craig G. Crandall

International Journal of Exercise Science: Conference Proceedings

Previous research has demonstrated women in the luteal phase have a greater time to pain threshold with similar cardiovascular responses during a cold pressor test (CPT), however, not all studies have confirmed these findings. PURPOSE: The purpose of this study was to test the hypothesis that during a CPT, perceived pain will be lower in females in the luteal phase, with no difference in the accompanying cardiovascular or autonomic responses to that CPT between menstrual cycle phases. METHODS: Thirty healthy women, 15 in the follicular phase of the menstrual cycle (age: 27 ± 5 yrs, body mass: 73 …
