Effects Of Lowering Body Temperature Via Hyperhydration, With And Without Glycerol Ingestion And Practical Precooling On Cycling Time Trial Performance In Hot And Humid Conditions, Megan Ross, Nikki Jeacocke, Paul Laursen, David Martin, Christopher Abbiss, Louise Burke

Research outputs 2012

Background: Hypohydration and hyperthermia are factors that may contribute to fatigue and impairment of endurance performance. The purpose of this study was to investigate the effectiveness of combining glycerol hyperhydration and an established precooling technique on cycling time trial performance in hot environmental conditions.Methods: Twelve well-trained male cyclists performed three 46.4-km laboratory-based cycling trials that included two climbs, under hot and humid environmental conditions (33.3 ± 1.1°C; 50 ± 6% r.h.). Subjects were required to hyperhydrate with 25 g.kg-1 body mass (BM) of a 4°C beverage containing 6% carbohydrate (CON) 2.5 h prior to the time trial. On two occasions, …

Acute Effects Of Three Different Stretching Protocols On The Wingate Test Performance, B L Franco, G R Signorelli, Gabriel Trajano, P B Costa, C G De Oliveira

Research outputs 2012

The purpose of this study was to examine the acute effects of different stretching exercises on the performance of the traditional Wingate test (WT). Fifteen male participants performed five WT; one for familiarization (FT), and the remaining four after no stretching (NS), static stretching (SS), dynamic stretching (DS), and proprioceptive neuromuscular facilitation (PNF). Stretches were targeted for the hamstrings, quadriceps, and calf muscles. Peak power (PP), mean power (MP), and the time to reach PP (TP) were calculated. The MP was significantly lower when comparing the DS (7.7 ± 0.9 W/kg) to the PNF (7.3 ± 0.9 W/kg) condition (p < 0.05). For PP, significant differences were observed between more comparisons, with PNF stretching providing the lowest result. A consistent increase of TP was observed after all stretching exercises when compared to NS. The results suggest the type of stretching, or no stretching, should be considered by those who seek higher performance and practice sports that use maximal anaerobic power.

Swing And Launch Parameters In Approach-Iron Shots Hit With Varying Height And Trajectory In Golf, Samuel J. Robertson, Angus Burnett

Research outputs 2012

The first aim of this study was to determine whether relationships existed between variability of swing and launch parameters and variability in shot outcome for straight golf shots. The second aim was to determine whether differences existed for swing and launch parameters in shots intentionally played with varying height and trajectory. Elite (n=20) and high-level amateur (n=22) golfers hit; 1) five straight shots of normal height and 2) nine shots of differing height (low, normal, high) and trajectory (straight, draw, fade). Variability of club attack angle, face angle and ball spin axis was significantly associated (p

Spatio-Temporal Modelling Of Malaria Incidence For Evaluation Of Public Health Policy Interventions In Ghana, West Africa, Simon K. Appiah, Ute Mueller, James Cross

Research outputs 2011

Malaria is a major challenge to both the public health and the socio-economic development of Ghana. Major factors which account for this situation include poor environmental conditions and the lack of prevention services. In spite of the numerous intervention measures, the disease continues to be the most prevalent health problem in the country. The risk assessment reports for Ghana were based on household surveys which provide inadequate data for accurate analysis of incidence cases. This poses a serious threat to planning and management for the health care delivery system in Ghana. Malaria transmission varies with geographical location and time (or …

Bullying In School And Cyberspace: Associations With Depressive Symptoms In Swiss And Australian Adolescents, Sonja Perren, Julian Dooley, Therese Shaw, Donna Cross

Research outputs pre 2011

Background Cyber-bullying (i.e., bullying via electronic means) has emerged as a new form of bullying that presents unique challenges to those victimised. Recent studies have demonstrated that there is a significant conceptual and practical overlap between both types of bullying such that most young people who are cyber-bullied also tend to be bullied by more traditional methods. Despite the overlap between traditional and cyber forms of bullying, it remains unclear if being a victim of cyber-bullying has the same negative consequences as being a victim of traditional bullying. Method The current study investigated associations between cyber versus traditional bullying and …

Testing An Exergame For Effectiveness And Attractiveness, Jeffrey Ronald Sinclair, Philip Hingston, Martin Masek, Kazunori Nosaka

Research outputs pre 2011

In this paper, we report on an experimental study in which we investigated the use of feedback mechanisms in exergames. We based the study around the Dual Flow model for exergame design, using biophysical feedback to control exercise intensity, and player performance feedback to control gameplay challenge. We found good success in controlling exercise intensity to achieve an effective workout, while controlling gameplay challenge to improve enjoyment and attractiveness was problematic. We offer some possible reasons for this, suggesting the need for further investigation.

Literacy And Recent History Of Diarrhoea Are Predictive Of Plasmodium Falciparum Parasitaemia In Kenyan Adults, Rodney Coldren, Trish Prosser, Fredrick Ogolla, Victor Ofula

Research outputs pre 2011

Background - Malaria is one of the most serious health problems in Kenya. In 2004, the Kenya Medical Research Institute and the US Army Medical Research Unit – Kenya surveyed adults in Samburu, Malindi, and Busia districts to determine socioeconomic risk factors for infection.

Methods - Sociodemographic, health, and antimalarial data were collected along with blood for malaria testing. A smear was considered negative only if no Plasmodium falciparum parasites were observed in 100 high-powered fields. Univariate analysis was performed with Pearson's Chi-square test and univariate logistic regression. A multivariate logistic regression model was then created which included only variables …
