Patellofemoral Syndrome, Prystyn M. Covington

International Journal of Exercise Science: Conference Proceedings

CLINICAL PRESENTATION & EXAM: Patellofemoral syndrome is an aching pain at the front of the knee and is common in athletes. Patellofemoral syndrome occurs due to many factors such as overuse (repetitive stress on the knee), trauma to the knee, surgery, and weak muscles. Surgery to the knee using the patellar tendon as a graft to fix the anterior cruciate ligament greatly increases the risk of pain. Many factors play a role in increasing the risk of developing patellofemoral syndrome such as sports, age, and gender. Most people who develop patellofemoral syndrome tend to be adolescents or young adults. …

METHODS: Fourteen participants (8 women, 6 men), with a mean (sd) age of 20.14 (0.91) yrs, completed the Ten-Item Personality Inventory to determine personality types (neuroticism, conscientiousness). Participants then performed in a random order, a high intensity physical activity (pacer test) and a low intensity …

Do Implantable, Progestin Only Contraceptives Alter The Bone Response To Unloading?, Ximena S. Vargas, Heather Cm Allaway, Sarah Little, Susan Bloomfield

International Journal of Exercise Science: Conference Proceedings

Hormonal contraception is routinely used by premenopausal women, including female astronauts, to suppress reproductive function. Long-acting reversible contraceptives (LARC-progestin only) have become a common choice amongst women due to their practicality. PURPOSE: Understand the interaction of unloading and LARC on bone health. We hypothesize that the decrease in bone mineral density (BMD) and cortical thickness of the tibia associated with hindlimb unloading (HU) will be lessened by LARC implantation. METHODS: Virgin female Sprague-Dawley rats (n=26; 4-mo-old) were singly housed and randomly assigned to placebo (PL) and LARC groups, via a slow-release etonogestrel pellet (0.00 vs. 0.09 vs. 0.17 …

An In Vitro Investigation Of The Effects Of Formoterol On Thyroid Hormone-Related Gene Expression During Myogenesis, Gena D. Guerin, Ryan A. Gordon, Emily L. Zumbro, Anthony A. Duplanty

International Journal of Exercise Science: Conference Proceedings

Thyroid hormone (TH) is a primary driver of skeletal muscle (SKM) metabolism as well as myogenesis through stimulation its genetic targets. The conversion and activation of thyroid hormone (T4 to T3) is controlled by local deiodinase 2 and 3 (DIO2, DIO3) activity. This leads to expression of nuclear receptors in promotor regions of specific genes including sarco/endoplasmic reticulum calcium ATPase 1(SERCA1), which is important for homeostasis of calcium regulation during muscle contraction. PURPOSE: The purpose of the study was to examine the effects of the exercise mimetic Formoterol (FORM), a beta-adrenergic receptor agonist, on the expression of thyroid hormone-related …

Current literature regarding risks of muscle damage associated with the FW are limited impacting possible use in exercise prescription and application. PURPOSE: The purpose of the study was to investigate the neuromuscular and biochemical responses to the FW when compared to an individual’s unloaded walking pattern (Non-weighted condition; NWC). METHODS: Fifteen participants (Mean ± SEM; age: 21.6 ± 0.5yo; ht: 172.5 …

The Effect Of Preparatory Motion And Visual Vs. Audio Cues On Response Time, Katherine Bricarell, Scott P. Mclean

International Journal of Exercise Science: Conference Proceedings

In many sports, athletes must perceive and interpret information quickly and effectively to provide sufficient time to plan and execute subsequent movements (Filipic et al., 2009). Preparatory movements in discrete motor skills may improve such performance by enhancing processes such as the stretch-shortening response (Bernardi et al., 1998). For example, in a tennis service return, athletes have incorporated a preparatory small vertical jump (referred to as a “split step”) to reduce reaction time (Filipic et al., 2017). Such preparatory movements are now being used by baseball and softball position players in an attempt to improve their fielding response. Supporting evidence …
