Estudio preliminar de la acción del músculo obturador interno sobre el diámetro biespinoso pélvico

Objective: To evaluate the effect of isometric active contraction of the internal obturator muscles on the bispinous diameter of the minor pelvis in nulliparous women. Subjects and methods: We performed a quasi-experimental study with pre-test-post-test: resting muscle position versus active contraction. We calculated the arithmetic mean of three consecutive measurements of the bispinous diameter of the minor pelvis obtained by magnetic resonance imaging performed in six nulliparous women. Results: No statistically significant differences (. P=.08) in the bispinous diameter were found between rest and during isometric contraction of the internal obturator muscles: in absolute values, the mean difference between the two measurements was - 5.4 pixels (95% CI: -11.8 to 0.9). Conclusions: The bispinous diameter of the minor pelvis cannot be increased in young nulliparous women by means of isometric contraction of the internal obturator muscles starting from a neutral position of both hips. © 2011 SEGO.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Efectos de un programa de entrenamiento estructurado de Gimnasia Abdominal Hipopresiva sobre la estática vertebral cervical y dorsolumbar

Objective. Try to target the effects of a training of Gymnastic Hipopressive (GH) of 10 meetings on the statics of the dorsolumbar column. Material. Different instruments of measurement were used: plummet, metric tape; as well as a camera Nikon Coolpix 5200, which images were treated with the computer software "Image Tool". Methods. A double blind study, where the population were of the same age. Twenty nine students, divided in 2 groups: the first group was trained with GH for an hour a week during ten weeks, with standardization of the exercises; while the second one followed only a postural training. To all of them a series of test were realized before the study and also later: flexibility of the vertebral column, muscular extensibility and enclosed pose measurements static and dynamic; so that every parameter was compared statistically by means of the test Student-Newman-Keuls. Results. We have found significant variations in the group of study with regard to the controls: in the static of the spine (cervical arrow: p = 0.002; dorsal p = 0.0001; lumbar p = 0.006) in the position of the occipital axis (p = 0.04); as well as also in the measurements of flexibility of the column, above all, in the flexion of trunk parameters (p = 0.005). And also in the isometric strength of the expanding muscles: Sorensen-Biering test (p = 0.02). Conclusions. The GH has an effect on the statics of the dorsolumbar column and believe that these results are very encouraging and must be considered, nevertheless, the research must continue.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Contribución al estudio anatomo-morfológico del suelo pélvico en la mujer asintomática: utilización de la imagen por RMN.

To confirm the results of previous studies demonstrating the morphology of the levator ani muscle in the living subject is different to that described in classic anatomical works; to evaluate the anatomical-morphological differences of the pelvic floor between nulliparous and multiparous women in order to analyze the influence of pregnancy and delivery.Comparative StudyEnglish AbstractJournal Articleinfo:eu-repo/semantics/publishe

The effect of a passive stretch training protocol on performance during a drop jump in humans.

Aim: Our study's aim is to show how a five-week stretch training protocol, based on passive stretching, can change muscle performance during a drop jump (stretch shortening cycle). Methods: This study observes in 8 healthy subjects (four males and four females), the effect of a 5-week passive stretch training protocol on the stretch shortening cycle (SSC) during the performance of a drop jump, and identify the architectural changes in the muscle. Subjects underwent measurements of their drop jump performance 3 times before, and 3 times after, the stretch training protocol. For the muscle tendon unit (MTU), changes were measured using the Hawkins and Hull's model. In order to calculate the length changes in the MTU, we measured the ankle and knee angles. For changes in the fascicle, the pennation angle and the thickness of the gastrocnemius medialis (GM) muscle were measured. Results: After the 5-week stretch training protocol, a significant increase in flexibility was observed in the fascicle during the first phase of the jump (a shortening of 10% after training vs. 20% before). No significant change was observed in the tendon, while the MTU showed a highly significant improvement (P<0.01) in muscle compliance during the landing phase. The average performance during the drop jump also showed a highly significant change (P<0.01). Conclusion: The results show a higher degree of flexibility in the MTU, enabled the latter to store more energy which was then converted to kinetic energy during the push-off phase of the drop jump.Journal Articleinfo:eu-repo/semantics/publishe

A red orange extract modulates the vascular response to a recreational dive: a pilot study on the effect of anthocyanins on the physiological consequences of scuba diving.

Nutritional antioxidants have been proposed as an expedient strategy to counter the potentially deleterious effects of scuba diving on endothelial function, flow-mediated dilation (FMD) and heart function. Sixteen volunteers performing a single standard dive (20 min at 33 m) according to US Navy diving procedures were randomly assigned to two groups: one was administered with two doses of 200 mg of an anthocyanins (AC)-rich extract from red oranges, 12 and 4 h before diving. Anthocyanins supplementation significantly modulated the effects of diving on haematocrit, body water distribution and FMD. AC administration significantly reduces the potentially harmful endothelial effects of a recreational single dive. The lack of any significant effect on the most common markers of plasma antioxidant capacity suggests that the mechanism underlying this protective activity is independent of the putative antioxidant effect of AC and possibly involves cellular signalling modulation of the response to high oxygen.info:eu-repo/semantics/publishe

The 'normobaric oxygen paradox': does it increase haemoglobin?

A novel approach to increasing erythropoietin (EPO) using oxygen (O2) (the 'normobaric oxygen paradox') has been reported in healthy volunteers. We investigated whether the EPO increase is sufficient to induce erythropoiesis by comparing two protocols of O2 administration.Journal ArticleSCOPUS: ar.jinfo:eu-repo/semantics/publishe
