Effects Of Ice Hockey Facial Protectors On The Response Time And Kinematics In Goal-Directed Tasks, P M. Dowler, D J. Pearsall, P J. Stapley

Faculty of Health and Behavioural Sciences - Papers (Archive)

Ice hockey facial protectors are essential to prevent eye (and, in some cases, dental) injuries but must also not encumber vision and, in turn, playersapos; performance. The purpose of this study was to investigate the effects of three different facial protection conditions on temporal and kinematic parameters in a goal-directed pointing task: helmet (control), visor, and cage. Start and end target switches captured temporal estimates (reaction time (RT), movement time, (MT), and response time (RT+MT)), while a 13-light target array and 6-camera Vicon Mx system were used to collect upper-body kinematics data (head and thorax orientation, shoulder and elbow joint …

Erps And The Evoked Cardiac Response To Auditory Stimuli: Intensity And Cognitive Load Effects, Robert J. Barry, Carlie Lawrence

Faculty of Health and Behavioural Sciences - Papers (Archive)

The evoked cardiac response (ECR) may be described as the sum of two independent response components: an initial HR deceleration (ECR1), and a slightly later acceleration (ECR2), hypothesized to reflect stimulus registration and cognitive processing load, respectively. This study investigated processing load effects in the ECR and the event-related potential (ERP). Stimulus intensity was varied within subjects, and cognitive load was varied between subjects, in a counting/no counting task with a long interstimulus interval. The ECR showed a significant effect of counting, but not intensity. ERPs showed the expected obligatory processing effects in the N1, and substantial effects of cognitive …

Effect Of High Amylose Maize Starches On Colonic Fermentation And Apoptotic Response To Dna-Damage In The Colon Of Rats, Ian L. Brown, Richard K. Le Leu, Graeme P. Young, Ying Hu

Background

We investigated in rats the effects of feeding different forms of high amylose maize starches (HAMS) rich in resistant starch (RS) to understand what the implications of RS heterogeneity might be for colonic biology, including innate cellular responses to DNA-damage.

Methods

A range of maize starches were compared: digestible cornstarch (Control), HYLON^® VII, Hi-maize^® 1043, Hi-maize^® 240, Hi-maize^® 260 and NOVELOSE^® 330. Included in the comparison was Cellulose. End-points after 4 weeks included: pH, short chain fatty acids (SCFA) levels, colonic epithelial cell kinetics and apoptotic response to carcinogen 'azoxymethane' in the colonic epithelium. …
