Modern Cavemen? Stereotypes And Reality Of The Ancestral Health Movement, David B. Schwartz, Hamilton M. Stapell 2013 Ancestral Health Society

Modern Cavemen? Stereotypes And Reality Of The Ancestral Health Movement, David B. Schwartz, Hamilton M. Stapell

Journal of Evolution and Health

Both academic and popular interest in the ancestral health movement, or “paleo” lifestyle, has grown rapidly in recent years. More people than ever are joining the movement, and more books and articles are being published on the topic. Media coverage and certain societal preconceptions of the movement have also increased. More often than not, followers of a paleo lifestyle are thought to be “modern cavemen”: athletic, single, meat-eating, young, white, and male. To test whether or not these stereotypes are true, the authors of the present study created the first large, academic survey (N = 3,967) of the ancestral health ...

Lateral ankle sprains most frequently occurs during sports. Individuals who experienced a first time ankle sprain had a high reoccurrence rate and residual symptoms and functional instability leading to chronic ankle instability (CAI). The purpose of this study was to investigate kinematic and kinetic differences between CAI individuals and healthy subjects in single-leg drop landing on a flat surface, an inverted surface and a combined surface of inversion and plantarflexion. A total of 17 subjects (6 subjects with chronic ankle instability, 11 healthy subjects) performed five trails in each of four dynamic movement conditions of drop landing from a height ...


The Effects Of 8 Weeks Of Low Dose Supplementation Of Creatine And Sodium Bicarbonate On Exercise Performance, Amanda Jessica Morris 2013 California Polytechnic State University

The Effects Of 8 Weeks Of Low Dose Supplementation Of Creatine And Sodium Bicarbonate On Exercise Performance, Amanda Jessica Morris

Master's Theses and Project Reports

Short-term (3-7 days), high doses of creatine (20g/d) and/or sodium bicarbonate (0.5g/kg body weight) supplementation increase exercise performance during short term high intensity activities; however, it remains unclear whether long-term, low doses of these supplements have a positive impact on exercise performance. The purpose of this study was to determine the effects of long-term (8 weeks), low dose creatine supplementation on exercise performance, and whether combining creatine and sodium bicarbonate supplementation has an additive effect. Sixty-three healthy, habitually active, adults (28 M, 35 W; 22+2 years; 23+ 3 BMI) were randomly assigned by sex to ...

Faculty of Health Sciences & Medicine Publications

Introduction

In this Research Review we have taken a slightly different tact than usual and chosen a position statement on a debatable topic that’s very worthy of serious attention. This article it is hot off the press and caught our eye, not because of its title, but because of all the gurus of strength training listed as authors, including (but not limited to) Faigenbaum, Stone, Pierce, Micheli, Kraemer, McBride and Chu. Our philosophy was, if all of these experts are collaborating on an article, it’s a must read. Even better, it’s an International Consensus on youth resistance ...

Research Review: Give Someone Enough Rope?, Michael Climstein, Joe Walsh

Faculty of Health Sciences & Medicine Publications

Introduction:

It’s a beautiful morning here in South East Queensland, and as I make my way back from an early surf I notice the personal trainers and performance enhancement specialists out in force, directing a number of outdoor strength and conditioning activities. There’s one new commonality in particular that seems to be becoming very popular among fitness professionals and their clients, namely ‘thick/heavy rope training’. And its popularity is substantiated as there are even several rope training/instruction certifications now available. Although there have been quite a number of research studies on jumping rope and kettlebells, this ...


The Effects Of Acute High- And Low-Intensity Exercise On Hsp70 And Hsp90 Accumulation In Rat Skeletal Myofibres And Vasculature, Hana Kowalchuk 2013 Western University

The Effects Of Acute High- And Low-Intensity Exercise On Hsp70 And Hsp90 Accumulation In Rat Skeletal Myofibres And Vasculature, Hana Kowalchuk

University of Western Ontario - Electronic Thesis and Dissertation Repository

Exercise induces cytoprotective stress proteins in blood vessels (BV) and skeletal myofibres. The localization and extent of induction with different exercise intensities is unclear. Rats (n=10 per group) were run at high (HIEX; 30m/min) versus low-intensity exercise (LOEX; 15m/min) for 1hr, sacrificed 24hr later. Sections of the white portion of the vastus were immunofluorescently stained for Hsp70 and Hsp90. It was hypothesized that: 1) a greater abundance of Hsp70 and Hsp90 would be observed in BVs following HIEX, 2) due to earlier recruitment, larger BVs would have a more robust response than small BVs, 3) more myofibres ...


Association Between Iliotibial Band Syndrome Status And Running Biomechanics In Women, Eric Henri Foch 2013 University of Tennessee, Knoxville

Association Between Iliotibial Band Syndrome Status And Running Biomechanics In Women, Eric Henri Foch

Doctoral Dissertations

Iliotibial band syndrome (ITBS) is common knee overuse injury that is twice as likely to afflict women compared to men. Etiological factors associated with ITBS include atypical biomechanics during running, as well as iliotibial band flexibility and hip abductor muscle weakness. This dissertation implemented a combination of discrete and continuous analyses to identify lower-extremity and trunk movement patterns that may be associated with ITBS injury status in female runners with current ITBS, previous ITBS, and controls. Three studies were conducted. Study 1 examined discrete joint and segment biomechanics during running, iliotibial band mechanics via musculoskeletal modeling and dynamic simulation, and ...

Effects Of Lateral Shoe Wedges And Toe-In Foot Progression Angles On The Biomechanics Of Knee Osteoarthritis During Stationary Cycling, Jacob Kale Gardner

Doctoral Dissertations

Exercise is important for individuals with knee osteoarthritis (OA) but certain activities can be painful and discourage participation. Cycling is commonly prescribed for OA but practically no previous literature exists. Due to their altered knee kinematics, OA patients may be at greater risk of OA progression or other knee injuries during cycling. The purpose of Study One was to investigate the effects of lateral wedges on knee joint biomechanics and pain in patients with medial compartment knee OA. The purpose of Study Two was to investigate the effects of toe-in foot progression angles on the same variables. Thirteen OA subjects ...
