[Epub ahead of print]Dehydration and Acute Weight Gain in Mixed Martial Arts Fighters Prior to Competition.Jetton AM, Lawrence MM, Meucci M, Haines TL, Collier SR, Morris DM, Utter AC.Source1Department of Health, Leisure, and Exercise Science; Appalachian State University, Boone, North Carolina, 28608. 2Department of Health Sciences, University of Rome 'Foro Italico', Rome, Italy.AbstractABSTRACT: The purpose of this study was to characterize the magnitude of acute weight gain (AWG) and dehydration in mixed martial arts (MMA) fighters prior to competition. Urinary measures of hydration status and body mass were determined 24 h prior and then again 2 h prior to competition in 40 MMA fighters (Mean SE, age: 25.2 0.65 yr, height: 1.77 0.01 m, body mass: 75.8 1.5 kg). AWG was defined as the amount of body weight the fighters gained in the 22 h period between the official weigh-in and the actual competition. On average, the MMA fighters gained 3.40 2.2 kg or 4.4% of their body weight in the 22 h period prior to competition. Urine specific gravity significantly decreased (P < 0.001) from 1.028 0.001 to 1.020 0.001 during the 22 h rehydration period. Results demonstrated that 39% of the MMA fighters presented with a Usg of greater than 1.021 immediately prior to competition indicating significant or serious dehydration. MMA fighters undergo significant dehydration and fluctuations in body mass (4.4% avg.) in the 24 h period prior to competition. Urinary measures of hydration status indicate that a significant proportion of MMA fighters are not successfully rehydrating prior to competition and subsequently are competing in a dehydrated state. Weight management guidelines to prevent acute dehydration in MMA fighters are warranted to prevent unnecessary adverse health events secondary to dehydration. Q J Exp Psychol (Hove). 2013 Feb 26. [Epub ahead of print]Timing of in situ visual information pick-up that differentiates expert and near-expert anticipation in a complex motor skill.Rosalie SM, Muller S.Sourcea Discipline of Exercise Sciences , RMIT University , Bundoora , VIC , Australia.AbstractThe timing of visual information pick-up for visual anticipation was examined by comparing the capability of multiple skill groups, expert and near-expert karate athletes and novices, to block attacks using an in situ temporal occlusion paradigm. Participants stood facing a karate opponent and then attempted to block attacks (kicks and punches), whilst their vision of attacks was occluded: (a) prior to onset of opponent motion (O1), (b) after preparatory head movement (O2), and (c) after initiation of the attacking motion (O3). A no occlusion control condition provided complete vision of attacks (O4). Results revealed that expert anticipation was not significantly different to that of near-experts at O1, but was significantly different to the other group across O2-O4. Expert anticipation, however, was significantly above chance across all occlusion conditions, but near-experts performed above chance at O3 and O4, whilst novices were better than chance at O4. Unexpectedly, unique evidence was found that expert anticipation could be differentiated from near-expert anticipation in the earliest occlusion condition, where it was found that only experts
