Morphological characteristics of European slalom canoe and kayak paddlers / Características morfológicas de los remeros de canoa y kayak de slalom europeos

SUMMARY: The primary aim of this study was to determine the morphology of elite canoe slalom paddlers and to identity if morphology differences existed between kayak and canoe paddlers. The survey included a total of 74 canoe slalom paddlers who competed in the 2018 European Championship. These competitors were assessed using a battery of anthropometric dimensions according to standardized anthropometric techniques and bioimpedance analysis using the multifrequency octopolar device Tanita MC-980. Elite slalom male competitors can be characterized to having average body height (~180 cm), average weight (~75 kg), with ectomorphic mesomorph somatotype (1.3 - 5.5 - 2.7), well developed trunk and arm muscles (biceps girth: 35.4 ± 1.8), low hypertrophy of legs and low body fat (8 ± 3.2 %). In addition, there are no significant differences between canoe (C1) and kayak (K1) paddlers. For female competitors we can conclude, there has been little change in anthropometric values through the decades. However, C1 competitors are younger, more mesomorphic and less ectomorphic.

RESUMEN: El objetivo de este estudio fue determinar la morfología de los remeros de canoa de slalom de élite e identificar si existían diferencias morfológicas entre los remeros de kayak y canoa. El análisis incluyó un total de 74 remeros de canoa slalom que compitieron en el Campeonato de Europa de 2018. Los competidores fueron evaluados mediante una batería de dimensiones antropométricas según técnicas antropométricas estandarizadas y análisis de bioimpedancia utilizando el dispositivo octopolar multifrecuencia Tanita MC-980. Los competidores masculinos de slalom de élite se pueden caracterizar por tener una estatura corporal promedio (~ 180 cm), un peso promedio (~ 75 kg), con somatotipo mesomorfo ectomorfo (1,3 - 5,5 - 2,7), músculos del tronco y del brazo bien desarrollados (circunferencia del bíceps: 35,4 ± 1,8), baja hipertrofia de piernas y baja grasa corporal (8 ± 3,2 %). Además, no existen diferencias significativas entre los remeros en canoa (C1) y kayak (K1). Para las competidoras, podemos concluir que se han observado pocos cambios en los valores antropométricos a lo largo de las décadas. Sin embargo, los competidores de C1 son más jóvenes, más mesomórficos y menos ectomórficos.

T-cell gamma/delta hepatosplenic lymphoma - prolonged remission induced by aggressive first line treatment.

T-cell gamma/delta hepatosplenic lymphoma is a primary extranodal lymphoma, distinct from other T/LGL lymphomas. The clinical course is aggressive, and despite use of the multiagent chemotherapy and young age of the patients, the median survival is less than 1 year. Curability of this disease is still uncertain. We reported a case of the successful intensive treatment with splenectomy, chemotherapy a first line autologous stem cell transplant. High intensity cytarabine- platinum containing regimen (EDHAP) may overcome primary resistance to conventional alkylating agents.

Effect of paddle grip on segmental fluid distribution in elite slalom paddlers.

Issues of high levels of muscular asymmetry have been associated with injury risk, and therefore have potential implications for decremental performance at the elite sport level. The aim of this current study was to assess the relationship between the segmental fluid distribution and the paddle grip in elite male and female slalom kayakers and canoeists. Eighty-four world-cup competitors (61 males and 23 females) took part in the study. Impedance analysis was used to assess segmental fluid asymmetry. The effect of paddle grip (loose/fixed hand in kayakers, lower/upper hand in canoeists), morphological dominance (dominant/non-dominant) and discipline (canoe/kayak) were evaluated by repeated measures ANOVA. The findings indicated a significant effect of paddle grip in canoeists on morphological asymmetry in upper limbs (arm of lower paddle hand mean fluid distribution 3.28, s=0.43 litres; arm of upper paddle hand mean fluid distribution 3.19, s=0.41 litres; P=0.000, [Formula: see text]=0.33). The sternmen demonstrated higher asymmetry between the arms of upper and lower paddle hand (mean 0.11, s=0.04 litres, P=0.000, [Formula: see text]=0.80) than the bowmen (mean 0.04, s=0.06 litres, P=0.015, [Formula: see text]=0.44) in double-canoes. Significant morphological asymmetry was found also in kayakers but the effect of paddle grip was not substantial. The use of segmental impedance analysis may be a suitable diagnostic tool for assessing morphological changes, which can be related to paddling training. Likewise muscular asymmetry is associated with injury risk; the evaluation of morphological changes during the training process may be considered by sport trainers and physical therapists.
