Lo que sí es importante, dice, es “aprender a diferenciar el dolor que causan las agujetas del dolor agudo producido por lesión o por fatiga muscular, puesto que eso son problemas que deben abordarse de otro modo”. Pero si persisten, debe practicarse ecografía muscular y empezar sesiones de fisioterapia y tratamiento médico, porque significa que la rotura ha ido más allá de la simple agujeta”, concluye el doctor Bigas. Y “completamente equivocada”, según explica el doctor en Medicina del Deporte Ángel Bigas, que recuerda que “se ha visto que las agujetas se producen por un trabajo excéntrico repetido a una intensidad demasiado elevada y, por lo general, aparecen a las 24 horas siendo el pico más alto de dolor (punzadas agudas) entre las 24 y 48 horas después del ejercicio”.
Todos los expertos también insisten en que hay que descansar. Hay también quien recurre a los antiinflamatorios, como el ibuprofeno o naproxeno, para aliviar el dolor, aunque son una ayuda a medias, puesto que no aceleran para nada la c uració n. Además, tal como advierten los especialistas, tomarlos antes de un ejercicio de resistencia puede llegar incluso a ser contraproducente. Se producen cuando el músculo es sometido a un ejercicio que tiene una exigencia superior al que suele realizar de forma habitual y, por lo general, van acompañadas de la inflamación de dicho músculo. En otras palabras, las agujetas son la respuesta normal a un esfuerzo extra y suponen un “proceso de adaptación que conduce a una mayor resistencia y fuerza para los músculos”, explica el entrenador personal Fito Florensa. 5. Yoga. Hay una creciente tendencia a recomendar yoga, y en especial sus técnicas de respiración, para reducir el dolor.

This helps maintain the low pressure formed in the venturi, which drives the secondary flow and thereby helps maintain the potential useful power output that can be achieved. Output can drop dramatically if the wave frequency differs from this design resonant frequency. The first pipes are provided with a series of holes spaced along its length and are connected to a flow conduit having an inlet into the body of water.

In one embodiment as shown in Figure 16 the spacers 114a, 114b can be connected by a septum 116 within the venturi section. Figure 14 shows an array of bi-directional pipes 100 with spacers elements 114 located within the diffuser sections 108a, 108b formed by adjacent pipes 100. Spacer elements 114 can be positioned within the diffuser section to allow a short chord length over the whole assembly to be used whilst still preserving a small effective angle to aid pressure recovery. The modules can be installed to be moveable within the body of water. The heights of the pipes are selected to suit the depth of the river where the structure is to be installed.
Figure 30 shows a general view of the apparatus in operation, with three structures 200 positioned along the length of the river 202. Further structures can be installed as required. For optimal functioning of the venturi pump the low pressure regime is required to be WO 2011/114155 PCT/GB2011/050523 12 preserved inside the venturi section in accordance with Bernoulli’s theorem. Contracciones con dolor de espalda . For the swept disc to gain exposure to the maximum incident current energy, the blades have to be very long which in turn requires sophisticated design and materials WO 2011/114155 PCT/GB2011/050523 2 to accommodate the stresses at the blade root. This problem can be lessened by making an installation very large but this in turn can lead to further complexity and expense and may lead beyond the limits of current engineering capability. A second aspect of the invention comprises an element for inclusion in an apparatus according to the first aspect of the invention for generating electricity using fluid flow in a body of water; the element defining an elongate flow passage and having an upstream side and a downstream side, the element being provided with a series of holes spaced along its length, the downstream side extending and tapering in the direction of flow, such that when elements are placed side by side in an array opposing walls of adjacent elements define a venturi section and a diffuser section extending downstream from the venturi section.

In order to achieve a low diffuser angle a pipe with a long chord length is obtained. With reference to Figure 15 the spacers 114 can be moveable in and out of the diffuser sections 108a, 108b. Movement of the spacers 114 changes the blockage ratio which can help performance in a tidal flow where the primary flow velocity is continuously variable. Providing a tapered section on the downstream side of the pipes helps aid pressure recovery as the primary flow decelerates out of the venturi. A larger pressure drop will help facilitate the secondary flow out up the holes to join the primary flow through the venturi. The inlet 188 for the secondary flow 190 can be located at the free edges to encourage the primary flow 192 to pass between the pipes 186 rather than around the free edges. A tube 174 is connected to each chamber and extends from the chamber to below the minimum free surface level 176 that the free surface of the secondary flow water will reach.
A substantially vertical barrier 226 extends upwards from the horizontal barrier 220. The vertical barrier 226 is impervious to water and retains the upstream water level above the top of the pipes. As the current flows through the venturi between the pipes an amplified head loss occurs in the venturi. The holes may comprise a closure mechanism operable between an open position and a closed position such that when the mechanism is in the closed position water is prevented from flowing through the holes. Any tendency for the free surface to depress in the pipe can have a detrimental effect on the performance of the device. By positioning management vanes across the pipes depression of the free surface can be inhibited.
The apparatus can further comprise horizontal flow management vanes arranged horizontally across the elements. The separation panel can be controllable to change the cross sectional area of the flow passage. This can help prevent flow dividing around the spacer unevenly and can help flow conditioning. The horizontal vanes can be flat to keep the flow substantially horizontal as it passes through the venturi. Dolor de brazo izquierdo y espalda . The aspect ratio of the profile of the pipes can be varied to provide the optimum performance of the array. The buoyancy means may be an airtight chamber into which air may be introduced or removed.
The system may comprise a buoyancy means in order to control or vary the buoyancy of the system and for example to raise or lower its depth in the water. The modules can use the current or tidal flow of the water to generate electricity. Each manifold can comprise a series of chambers, each chamber positioned adjacent the end of a flow passage; and a feeder tube extending from the chamber and having an inlet located below the series of chambers. With a V shaped front end on the upstream side a larger pressure drop in the venturi may occur. The horizontal septums may WO 2011/114155 PCT/GB2011/050523 5 help minimise the size of vortexes in the vertical plane between adjacent elements. Water 62 enters the flow conduit via the inlet and the pipes 50 are connected to the outlets of the manifold 64 such that flow of water past the arrangement of pipes causes the WO 2011/114155 PCT/GB2011/050523 10 venturi to act as venturi pumps inducing flow from inside the pipes through the holes so as to draw water through the flow conduit and drive the turbine.
Gaps may be incorporated into the WO 2011/114155 PCT/GB2011/050523 17 SMEC apparatus to permit the passage of water crafts, fish or marine mammals up and down the river. The roughened surface helps to promote turbulent flow in the boundary layer which can promote mixing and aid pressure recovery. Como disminuir el dolor muscular . Each element can comprise a moveable separation panel to separate the upstream side from the downstream side.
The aspect ratio of the profile of the pipe is ratio of the length of L of the profile and of the width W of the profile at its widest point. The invention is broadly based on the technology disclosed in W02008/015047, which describes an apparatus comprising an arrangement of first and second pipes for generating electricity using tidal, wave or current flow in a body of water. As shown in Figure 31 the modules can comprise a buoyancy section 92 or external float, which keeps the top of the pipe 20 at the water surface level 94. As the water level 94 falls the SMEC can roll on the river bed 96 such that the holes 30 of the pipes 20 and the module will stay substantially submerged as the water level rises and falls.

Each flow passage can comprise a series of chambers positioned vertically down the flow passage; and a feeder tube extending from each chamber and having an inlet located below the series of chambers. The use of controllable-pitch turbines can help maximise performance. The hydrodynamic efficiency of the power offtake turbines can affect the overall performance of the apparatus. Figures 10 and 11 show different embodiments of the pipes for the apparatus having differing bracings, struts and plate arrangements to provide strengthening to the pipes. Other high alloy steels and metals can also be used where appropriate. Figures 6-11 show examples of profiles of the pipes that can be used for forming the apparatus for use in unidirectional flows. This will help sustain a reduced pressure drop downstream of the turbine which increases the power that can be extracted from the secondary flow. The pipe 70 has a tapered elongated downstream side 74 which is longer then the upstream side 72 and closed off from the upstream side 72. Holes 78 are located along the length of the pipe70 in the upstream side 72 near the boundary with the downstream side 74 for secondary flow from the flow passage 76 into the venturi.
