Assessment Of Hrv After Maximal Exercise In Trained Postmenopausal Women, Julia Orri, E. M. Hughes, D. G. Mistry, A. Scala

Kinesiology (Formerly Exercise and Sport Science)

Increased parasympathetic tone achieved with endurance training may provide cardioprotection after menopause. To compare heart rate variability (HRV) from rest through maximal exercise and recovery in trained postmenopausal women. Thirtysix postmenopausal women who self-reported training at either moderate (MOD; 3-5.9 METS; 58.9±4.4 year) or vigorous (VIG; >6 METS; 59.7±5.2 year) intensities participated. HRV was measured for 5 min in the supine position, in the last minute of the VO2max test and after 2 min of active recovery. HRV in MOD and VIG was compared using a factorial ANOVA with repeated measures on time. MOD and VIG responded similarly over the …

The Effect Of Movement Variability On Putting Proficiency During The Golf Putting Stroke, Ashley K. Richardson, Andrew C.S. Mitchell, Gerwyn Hughes

Kinesiology (Formerly Exercise and Sport Science)

Movement variability has been considered important to execute golf swing yet is comparatively unexplored regarding the golf putt. Movement variability could potentially be important considering the small margins of error between successful and a missed putt. The aim of this study was to assess whether variability of body segment rotations influence putting performance (ball kinematic measures). Eight golfers (handicap range 0-10) performed a 3.2 metre level putt wearing retro-reflective markers which were tracked using a three-dimensional motion analysis system sampling at 120 Hz. Ball roll kinematics were recorded using Quintic Ball Roll launch monitor. Movement (segment) variability was calculated based …

Full Gait Cycle Analysis Of Lower Limb And Trunk Kinematics During Walking In Participants With And Without Ankle Instability, Lynsey Northeast, Charlotte N. Gautrey, Lindsay Bottoms, Gerwyn Hughes, Andrew C.S. Mitchell, Andrew Greenhalgh

Kinesiology (Formerly Exercise and Sport Science)

Background: Chronic ankle instability (CAI) has previously been linked to altered lower limb kinematics and muscle activation characteristics during walking, though little research has been performed analysing the full time-series across the stance and swing phases of gait. Research Question: The aim of this study was to compare trunk and lower limb kinematics and muscle activity between those with chronic ankle instability and healthy controls. Methods: Kinematics and muscle activity were measured in 18 (14 males, 4 females) healthy controls (age 22.4 ± 3.6 years, height 177.8 ± 7.6 cm, mass 70.4 ± 11.9 kg, UK shoe size 8.4 ± …

The Relationship Between Sports Sponsorship And Corporate Financial Returns In South Africa, Michael Goldman, Julian Blake, Sonja Fourie

Sport Management

Purpose

Sponsorship is a major contributor to income in the South African sports arena, and is a critical component allowing sports unions to remain financially viable and sustainable. Sports sponsoring companies, however, have long questioned the financial returns generated from these ventures. The purpose of this paper is to understand whether financial returns of companies with sports sponsorship in South Africa are significantly different to those without. This research was conducted on Johannesburg Stock Exchange (JSE) listed companies that sponsored sport consistently between 2000 and 2015 for a period of two years. A quantitative methodology was employed whereby share price, …

Corruption And Soccer In Africa: Empirical Evidence On The Determinants Of Association Soccer Success In The Continent, Mustafa Zahid

Undergraduate Honors Theses

Despite the popularity of soccer in Africa, African teams tend to underperform in international competitions such as the World Cup relative to European and South American teams. Studies have been conducted on what determines performance in international soccer. These studies stress the importance of wealth, talent pool, and soccer culture on determining performance. However, these studies focus more generally on the entire world, and, in some instances, omit African nations due to a lack of data. Additionally, the focus on a wide sample of the world results in the omission of some potentially crucial variables in relation to Africa, specifically …
