Efectos de la periodización nutricional en la composición corporal de corredores de media distancia de Djibouti / Efeitos da periodização nutricional na composição corporal em corredores de média distância do Djibutiano / Effects of nutritional periodization on the body composition of middle-distance runners from Djibouti

RESUMEN Introducción: La composición corporal es un indicador fundamental para definir el estado nutricional del corredor. Objetivo: El estudio tuvo como objetivo evaluar los efectos de la intervención de periodización nutricional en la composición corporal de corredores juveniles djiboutianos de élite en distancia media. Materiales y métodos: La muestra fue de 22 corredores masculinos, en edades comprendidas entre 16 y 18 años. Para la valoración, se diseñó un experimento constituido por 11 sujetos en el grupo control y 11 en el experimental. Como mediciones antropométricas se tomaron el peso, estatura y seis panículos adiposos para evaluar el porcentaje de grasa, índices de adiposidad, índice de masa corporal y el de sustancia corporal activa pues, para llevar el seguimiento de la intervención propuesta, se realizó una entrevista de recordatorio 24 horas de siete días. Resultados: Se diseñó una dieta periodizada, con la manipulación de los carbohidratos. La periodización nutricional con alta y baja ingesta de carbohidratos durante 12 semanas disminuyó significativamente (p< 0,05) el porcentaje de grasa, sin alterar el peso corporal ni el índice de sustancia corporal activa en los corredores djiboutianos de media distancia juveniles del grupo experimental. Conclusiones: Los resultados expuestos contribuyen a mejorar el control biomédico del entrenamiento en los corredores de élite juveniles de distancia media en Djibouti, ya que existían limitaciones de datos sobre su composición corporal y el efecto que pudiera tener la nutrición periodizada sobre esos indicadores

SÍNTESE Introdução: A composição corporal é um indicador chave na definição do estado nutricional do corredor. Objetivo: O estudo visava avaliar os efeitos da intervenção de periodização nutricional sobre a composição corporal em corredores de elite júnior djibutianos de meia distância. Materiais e métodos: A amostra consistiu de 22 corredores masculinos, de 16-18 anos de idade. Para a avaliação, foi projetado um experimento com 11 sujeitos no grupo de controle e 11 no grupo experimental. Como medidas antropométricas, foram tomadas medidas de peso, altura e seis panniculi adiposos para avaliar a porcentagem de gordura, índices de adiposidade, índice de massa corporal e índice de substância corporal ativa. Para acompanhar a intervenção proposta, foi realizada uma entrevista de lembrete de sete dias, 24 horas por dia. Resultados: Foi projetada uma dieta periódica, com a manipulação de carboidratos. A periodização nutricional com alta e baixa ingestão de carboidratos por 12 semanas diminuiu significativamente (p<0,05) o percentual de gordura, sem alterar o peso corporal ou o índice de substância corporal ativa em corredores djibutianos juvenis de meia distância no grupo experimental. Conclusões: Os resultados acima contribuem para melhorar o monitoramento biomédico do treinamento em corredores de elite de distância média júnior em Djibuti, já que havia limitações de dados sobre sua composição corporal e o efeito que a nutrição periodizada poderia ter sobre esses indicadores.

ABSTRACT Introduction: Body composition is a fundamental indicator to define the nutritional status of the runner. Objective: The study aimed to evaluate the effects of the nutritional periodization intervention on the body composition of elite junior Djiboutian runners in middle distance. Materials and methods: The sample consisted of 22 male runners, aged between 16 and 18 years. For the assessment, an experiment consisting of 11 subjects in the control group and 11 in the experimental roup was designed. As anthropometric measurements, weight, height and six adipose tissue were taken to evaluate the percentage of fat, adiposity index, body mass index and active body substance index, since, in order to monitor the proposed intervention, an interview of reminder 24 hours seven days. Results: A periodized diet was designed, with the manipulation of carbohydrates. Nutritional periodization with high and low carbohydrate intake for 12 weeks significantly (p<0.05) decreased percentage fat without altering body weight or active body substance index in juvenile middle-distance Djiboutian runners from the experimental group. Conclusions: The exposed results contribute to improve the biomedical control of training in elite junior middle-distance runners in Djibouti, since there were data limitations on their body composition and the effect that periodized nutrition could have on these indicators.

Unilateral versus bilateral laparoscopic ovarian electrocautery in patients with polycystic ovarian syndrome: a prospective hormonal and clinical study

The aim of this work was to assess the efficacy of unilateral and bilateral laparoscopic ovarian electrocautery in correcting the endocrine abnormalities and inducing ovulation in infertile patients with clomiphene citrate resistant PCOS. Fifty patients were included in this study. They were randomly allocated to either unilateral [25 cases] or bilateral [25 cases] laparoscopic ovarian electrocautery. Serum LH FSH and testosterone [T] levels were estimated in the early follicular phase before and after the operation. The cases were followed postoperatively for 6 months to detect, the occurrence of ovulation and pregnancy. A highly significant postoperative fall of serum LH and LH/FSH ratio [P<0.0001] was detected following either unilateral or bilateral ovarian electrocautery. Also serum FSH increased significantly [P<0.05] and serum T decreased significantly [P<0.05]. Ovulation occurred in 72% of the patients following unilateral ovarian electrocautery and in 76% following bilateral ovarian electrocautery. It was found that neither the preoperative LH, FSH nor T level could be used to predict the occurrence of postoperative response. Unilateral ovarian electrncautery resulted in bilateral ovarian activity in all responders. Pregnancy occurred in 48% of the patients of unilateral ovarian electrocautery and in 56% of the patients of bilateral ovarian electrocautery. The less traumatizing technique of unilateral laparcscopic ovarian electrocautery resulted in endocrine and clinical effects nearly similar to that produced by bilateral ovarian elctrocautery with no statistically significant difference. It has the advantage of preserving one side of the pelvis away from possible postoperative adhesions

role of serum creatine kinase as a marker for tubal pregnancy

There has been a great deal of interest to find a biochemical marker for tubal pregnancy which can be employed as a single randomly timed assay. The role of creatinekinase [CK] as a marker for tubal pregnancy has been evaluated in a prospective controlled study. We compared CK levels in the study group of 31 patients with tubal pregnancy and two control groups. 31 patients having missed abortion and 31 patients with normal pregnancy at comparable gestational age. CK level was > 50 IUIL. in all patients with tubal pregnancy, significantly higher than the level in either of the two control groups [P< 0.01]. We conclude that CK can serve as an additional diagnostic tool in the diagnosis of tubal pregnancy
