Interceptive actions require individuals to time their movements with an external event. To meet the intense spatial-temporal demands needed for successful interception, a tight coupling and coordination between perceptual and motor processes is required. The control strategy that underlies successful performance is a matter of debate. On the one hand, a(More)
We determined the gaze and stepping behaviours of elite ballet dancers and controls as they walked normally and along progressively narrower 3-m lines (l0.0, 2.5 cm). The ballet dancers delayed the first step and then stepped more quickly through the approach area and onto the lines, which they exited more slowly than the controls, which stepped immediately(More)
Heat and hypoxia exacerbate central nervous system (CNS) fatigue. We therefore investigated whether essential amino acid (EAA) and caffeine ingestion attenuates CNS fatigue in a simulated team sport-specific running protocol in a hot, hypoxic environment. Subelite male team sport athletes (n = 8) performed a repeat sprint running protocol on a nonmotorized(More)
Interceptive actions, such as catching, are a fundamental component of many activities and require knowledge of advanced kinematic information and ball flight characteristics to achieve successful performance. Rather than combining these sources of information, recent exploration of interceptive actions has presented them individually. Thus, it still is(More)
Quiet eye (QE) is a robust phenomenon in golf putting and expert players frequently demonstrate longer QE periods (i.e., the final fixation prior to the onset of the putting motion) relative to their less-skilled counterparts. In this experiment we used a pre-test/post-test design to determine whether we could use novel training aids and instructions to(More)
This study investigated the effectiveness of action observation (AO) on facilitating learning of the power clean technique (kinematics) compared with traditional strength coaching methods and whether improvements in performance (kinetics) were associated with an improvement in lifting technique. Fifteen subjects (age, 20.9 ± 2.3 years) with no experience in(More)
This study examined how practice distribution influenced performance and learning of a discrete sport skill, the Australian Football (AF) handball pass. A secondary aim was to assess whether previous experience playing competitive Australian Football influenced learning. Participants performed the handball 50 times (5 blocks x 10 repetitions) using either a(More)
The integration of separate, yet complimentary, cortical pathways appears to play a role in visual perception and action when intercepting objects. The ventral system is responsible for object recognition and identification, while the dorsal system facilitates continuous regulation of action. This dual-system model implies that empirically manipulating(More)
