The Onset Of Exercise-Associated Hyponatremia And Individual Differences In Inappropriate Arginine Vasopressin Excretion: A Review Of Proposed Mechanisms, Michelle Stehman, Stephen A. Maris

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 10, 2021. Exercise-associated hyponatremia (EAH) has been reported to develop during endurance events such as triathlons and marathons. As these events become more popular, the incidence of developing EAH also increases. The development of EAH is commonly associated with the overconsumption of hypotonic fluids such as water and tends to be more prevalent in females. There is also evidence to suggest the inappropriate secretion of arginine vasopressin (AVP) leading to water retention may predispose an individual for developing EAH, especially when coupled with the overconsumption of fluids. Recent research …

The Effects Of Estrogen In The Glucoregulatory Response To Exercise In Type 1 Diabetes, Mitchell James Sammut

Undergraduate Student Research Internships Conference

Regular exercise has shown to benefit the health of individuals with type 1 diabetes mellitus (T1DM). However, a barrier to regular exercise for this population is the fear of low blood glucose (BG) levels, also known as hypoglycemia. Hypoglycemia can result in short and long-term side-effects, such as recurring loss of consciousness or in severe cases death.

In non-diabetics, sex-related differences in fuel selection during exercise are well established. Women shift towards using fats as fuel whereas men rely mostly on sugars (i.e., carbohydrates) for energy production. Exercise during the luteal phase of the female menstrual cycle, where estrogen levels …

Comparison Of Different Neuromuscular Facilitation Techniques And Conventionalphysiotherapy In Knee Osteoarthritis, Ayşenur Gökşen, Fi̇li̇z Can, Seval Yilmaz, Feza Korkusuz

Turkish Journal of Medical Sciences

Background/aim: This study was conducted to compare the effects of conventional physiotherapy and two different `proprioceptive neuromuscular facilitation' (PNF) techniques on knee muscle strength, knee muscular endurance, and proprioception in knee osteoarthritis (KOA). Materials and methods: The study included 35 patients between the ages of 47 and 62 who were diagnosed with stage 1-2 KOA. The patients were divided into three groups with block randomization method as Repeated Stretching Group (N = 12) With Repeated Stretching Technique, Combined Isotonic Contraction Group (N = 11) With Combined Isotonic Contractions (CIC) Technique, And Conventional Physiotherapy Group (n = 12). PNF was applied …

Exercise Capacity, Muscle Strength, Dyspnea, Physical Activity, And Quality Of Life Inpreoperative Patients With Lung Cancer, Gülşah Barği, Ece Baytok, Zeli̇ha Çeli̇k, Merve Şatir Türk, Ali̇ Çeli̇k, İsmai̇l Cüneyt Kurul, Meral Boşnak Güçlü

Turkish Journal of Medical Sciences

Background/aim: To detect the extent to which physical impairments are observed in patients with lung cancer awaiting lung surgery, exercise capacity, muscle strength, physical activity, dyspnea, and quality of life (QOL) were objectively compared between the patients and healthy individuals in current study. Materials and methods: Patients with lung cancer (n = 26) and healthy individuals (n = 21) were included. Exercise capacity, respiratory (maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP)) and quadriceps femoris muscle strength, physical activity, dyspnea and QOL were evaluated using 6-min walk test (6-MWT), a mouth pressure device, a hand-held dynamometer, a metabolic holter device, …

Lutein/Zeaxanthin Isomers Regulate Neurotrophic Factors And Synaptic Plasticity Intrained Rats, Cemal Orhan, Füsun Erten, Beşi̇r Er, Mehmet Tuzcu, Nurhan Şahi̇n, Öznur Ece Durmaz Kurşun, Vijaya Juturu, Kazi̇m Şahi̇n

Turkish Journal of Medical Sciences

Background/aim: This study was conducted to elucidate the effects of lutein/zeaxanthin isomers (L/Zi) on lipid metabolism, oxidative stress, NF-ΚB/Nrf2 pathways, and synaptic plasticity proteins in trained rats. Materials and methods: Wistar rats were distributed into four groups: 1) control, 2) L/Zi: rats received L/Zi at the dose of 100 mg/kg by oral gavage, 3) exercise, 4) exercise+L/Zi: rats exercised and received L/Zi (100 mg/kg) by oral gavage. The duration of the study was eight weeks. Results: Exercise combined with L/Zi reduced lipid peroxidation and improved antioxidant enzyme activities of muscle and cerebral cortex in rats (p < 0.001). In the Exercise + L/Zi group, muscle and cerebral cortex Nrf2 and HO-1 levels increased, while NF-ΚB levels decreased (p

Effects Of Intracerebroventricularly Administered Opioid Peptide Antagonistson Tissue Glycogen Levels In Rats After Exercise, Ayşe Şebnem İlhan, Şevi̇n Güney, Si̇bel Di̇ncer

Turkish Journal of Medical Sciences

Background/aim: Physical exercise is a state of physiological stress that requires adaptation of the organism to physical activity. Glycogen is an important and essential energy source for muscle contraction. Skeletal muscle and liver are two important glycogen stores, and the energy required to maintain exercise in rodents are provided by destruction of this glycogen depot. In this study, the effects of endogenous opioid peptide antagonism at the central nervous system level on tissue glycogen content after exhaustive exercise were investigated. Materials and methods: Rats had intracerebroventricularly (icv) received nonspecific opioid peptide receptor antagonist, naloxone (50 μ/10 μL in saline) and …

The Support Person's Preferences And Perspectives Of Physical Activity Programs For Older Adults With Cognitive Impairment, Terence W. H. Chong, Emily You, Kathryn A. Ellis, Kay L. Cox, Karra D. Harrington, Stephanie R. Rainey-Smith, David Ames, Nicola T. Lautenschlager, Aibl Research Group

Research outputs 2014 to 2021

Objectives: Physical activity (PA) is beneficial for older adults' cognition. There is limited research investigating perspectives of support persons (SPs) of next-of-kins (NOKs) with cognitive impairment. This exploratory study aimed to investigate perspectives of SPs of older adults with Alzheimer's Dementia (AD) or Mild Cognitive Impairment (MCI). Methods: A telephone survey of 213 SPs of NOKs from the Australian Imaging, Biomarkers and Lifestyle Flagship Study of Ageing (AIBL) was undertaken to quantitatively assess SPs' beliefs and knowledge about PA benefits, current PA level of their NOK, and PA program preferences. The contribution of age, gender, diagnosis and mental health symptoms …
