Análisis de composición corporal y somatotipo de judokas infantiles y cadetes en el campeonato de españa 2012 / Analysis of body composition and somatotype of junior and cadet judokas in the 2012 spanish championship

El objetivo de este estudio es analizar la composición corporal y el somatotipo de judokas participantes en el campeonato escolar de España. Fueron estudiados 57 niños de categoría infantil (13,33±0,66 años) y 40 niños de categoría cadete (15,18±0,74 años) (n=97), mediante un fraccionamiento corporal tetracompartimental y el análisis del somatotipo según el método de Heath-Carter. En categoría infantil obtuvimos una media de 48,11% de masa muscular, 25,49% de masa residual, 14,80% de masa grasa y 11,56% de masa ósea. En categoría cadete, 47.67% de masa muscular, 25,25% de masa residual, 16,46% de masa grasa y 10,57% de masa ósea. Se encontraron diferencias significativas únicamente en el compartimiento de masa ósea entre ambos grupos. El somatotipo medio para ambas categorías es Ectomorfo Balanceado.

The aim of the study was to analyze body composition and somatotype of the judokas participants at the Spanish Junior Championship. We analyzed 97 male judokas (n= 97): 57 junior (13.33±0.66 years) and 40 cadets (15.18±0.74 years), through a Tetracompartimental Fractionation and the somatotype through a Heath-Carter method. In junior category, 48.11% of muscle mass, 25.49% of residual mass, 14.80% of fat mass and 11.56% of bone mass. In cadet category, 47.67% of muscle mass, 25.25% of residual mass, 16.46% of fat mass and 10.57% of bone mass. Significant differences were found only in the bone compartment between both groups. The average somatotype for both categories was Ectomorph Balanced.

Exhaled breath condensate analysis after long distance races.

The impact of an endurance race on pulmonary pro-oxidative formation and lipoperoxidation was evaluated using exhaled breath condensate (EBC). 3 groups of 12, 12 and 17 healthy recreational runners of both sexes ran 10, 21.1 and 42.2 km, respectively. EBC samples were obtained before the run and at 20 and 80 min post run. Concentrations of H2O2, NO2 - , malondialdehyde and pH were determined. The 10 km group showed no post-run variations for H2O2 and NO2 - concentrations. The 21.1 km group showed significant increments for NO2 - , and H2O2 concentrations in 20 min and 80 min samples. The 42.2 km group, showed increased NO2 - concentration in 20 min and 80 min samples, while H2O2 concentration increased only in the 20 min sample. In the 10 and 42.2 km groups neither malondialdehyde concentration nor pH showed differences. The 42.2 km group exhibited ΔH2O2 and ΔNO2 - medians higher than the 10 km group. ΔpH median decreased in 21.1 and 42.2 km groups, exhibiting values significantly lower than the 10 km group. ΔH2O2 y ΔNO2 - correlated directly with race time, while ΔpH, correlated inversely. In conclusion, intense prolonged exercise favors the increase in pulmonary pro-oxidative levels, with no modifications on lipoperoxidation. Running time relates to the magnitude of acute post exercise pro-oxidative formation.

Arthroscopic treatment of the snapping iliopsoas tendon through the central compartment of the hip: a pilot study.

We undertook a prospective pilot study to determine whether arthroscopic surgery through the central compartment of the hip was effective in the management of a snapping iliopsoas tendon. Seven patients were assessed pre-operatively and at three, six, 12 and 24 months after operation. This included the assessment of pain on a visual analogue scale (VAS) and function using the modified Harris hip score. All the patients had resolution of snapping post-operatively and this persisted at follow-up at two years. The mean VAS score for pain fell from 7.7 (6 to 10) pre-operatively to 4.3 (0 to 10) by three months (p = 0.051), and to 3.6 (1 to 8) (p = 0.015), 2.4 (0 to 8) (p = 0.011) and 2.4 (0 to 8) (p = 0.011) by six, 12 and 24 months, respectively. The mean modified Harris hip score increased from 56.1 (13.2 to 84.7) pre-operatively to 88.4 (57.2 to 100) at one year (p = 0.018) and to 87.9 (49.5 to 100) at two years (p = 0.02). There were no complications and no weakness occurred in the musculature around the hip. Our findings suggest that this treatment is effective and would support the undertaking of a larger study comparing this procedure with other methods of treatment.

Cerivastatin improves insulin sensitivity and insulin secretion in early-state obese type 2 diabetes.

In a double-blind, placebo-controlled, randomized crossover study, 15 stable mild hyperglycemic patients without treatment and with features of metabolic syndrome were treated with cerivastatin (0.4 mg/day) or placebo for 3 months. The insulin sensitivity index during the euglycemic-hyperinsulinemic clamp (EHC; 5.4 mmol/l; 80 mU x m(-2) x min(-1)) was increased by cerivastatin treatment (66.39 +/- 3.9 nmol x lean body mass [LBM](-1) x min(-1) x pmol(-1) x l(-1)) as compared with placebo (58.37 +/- 3.69 nmol x LBM(-1) x min(-1) x pmol(-1) x l(- 1); P < 0.01) by 13.7%. Glucose oxidation during EHC was significantly higher with statin treatment (16.1 +/- 1.37 micromol x LBM(-1) x min(-1)) as compared with placebo (14.58 +/- 1.48 micromol x LBM(-1) x min(-1); P < 0.05). During hyperinsulinemia (approximately 800 pmol/l) in EHC steady-state, lipid oxidation was significantly decreased and respiratory quotient was significantly increased with statin treatment (0.33 +/- 0.05 mg x LBM(-1) x min(- 1), 0.94 +/- 0.01) as compared with placebo (0.48 +/- 0.06 mg x LBM(-1) x min(-1), 0.91 +/- 0.01; P < 0.01 and P < 0.05, respectively). During statin treatment, the first-phase insulin response increased from 2.07 +/- 0.28 to 2.82 +/- 0.38 pmol x l(-1) x pmol(-1) (P < 0.05). The second phase of insulin responses examined by C-peptide and insulin levels averaged during the hyperglycemic clamp (20 mmol/l) was unchanged. In conclusion, this study demonstrates that 0.4 mg cerivastatin therapy improves first-phase insulin secretion and increases insulin-mediated glucose uptake and respiratory quotient in the early state of obese type 2 diabetes.

Delayed diagnosis of fatigue fractures in the elderly.

A retrospective study was made of 30 stress fractures in elderly patients engaged in noncompetitive sporting activities, mostly marching and running. Fractures were located exclusively in the lower limbs. In many cases the diagnosis was delayed and in several cases was incorrect because the stress fracture was mistaken for other conditions. Given that the number of senior citizens engaged in active life and sporting activities is constantly growing, physicians should be aware of this type to ensure early diagnosis and appropriate treatment.
