ABSTRACT
Capsuloligamentous injury at the first metatarsophalangeal (MTP) joint is a common traumatic injury during physical activity, particularly on artificial turf. Mechanism of injury include excessive flexion, extension, or valgus stress. We report a non-operatively treated capsuloligamentous injury at the first MTP joint, which did not occur traumatically but developed by a stress-related mechanism in a collegiate rower.

El objetivo de esta investigación fue describir las características antropométricas de remeros varones de la categoría juvenil chilenos que han participado en un proceso de selección durante los años 2011 y 2012. Se evaluaron 27 deportistas con una edad promedio de 16,95+/-0,97 en los cuales se midieron 25 variables antropométricas. Se calculó la composición corporal pentacompartimental, el somatotipo y la proporcionalidad. Se utilizó estadística descriptiva para la caracterización de los deportistas. El promedio de los resultados mostró que los remeros juveniles chilenos presentan un porcentaje de masa muscular elevado, de tejido adiposo bajo y un somatotipo mesomórfico balanceado.
The aim was to describe the anthropometric characteristics of Chilean junior category male rowers who participated in a selection process during the years 2011 and 2012. We evaluated 27 athletes with a mean age of 16.95+/-0.97 in which 25 anthropometric variables were measured. We calculated pentacompartimental body composition, somatotype and proportionality. Descriptive statistics were used to characterize athletes. The average of results showed that Chilean junior rowers have a high percentage of muscle mass, low body fat and a balanced mesomorphic somatotype.

The purpose of this study was to investigate the effects of creatine loading on rowing performance in well-trained male competitive rowers (age 19.4±0.2 yr, height 182.2 ± 1.2 cm, weight 76.6±1.1 kg, mean±SE) . Twenty subjects were randomly separated into creatine (n=10) or placebo group (n=10) . Subjects performed simulated 2000 m rowing race and 20 sec maximal rowing on a rowing ergometer, before and after 6 days of creatine (20g of creatine monohydrate plus 4g of lactose per day) or placebo (24g of lactose per day) ingestion, The creatine and placebo were administered in a double-blind research design. Performance time for 2000 m rowing was improved significantly from 407.9±5.3sec to 404.7±5.4sec (p<0.01) in the creatine group, but no significant changes were observed in the placebo group. No significant changes were observed in power output during 20 sec maximal rowing in either groups. These results suggest that creatine loading can enhance performance in simulated 2000 m rowing race in well-trained competitive male rowers but has no beneficial effect on 20 sec maximal rowing.
