Conclusion: These results confirm that elite divers present a potentiation of the well-known apnoea response in both SA and DA conditions. This response is associated with higher brain perfusion which may partly explain the high levels of world apnoea records. (Source: Acta Physiologica)

REVOLUTION SHOE POCKET

• The Revolution fin shoe pocket is conceived and designed like a real shoe, and is surely the most comfortable shoe pocket available on the market today.
• It is available in seven sizes: from 40 to 46.
• The vamp of the shoe pocket is premoulded and built in nylon with a polyurethane covering.
• Both materials are water-proof and highly resistant in water.
• The padding and internal sole are also water-repellent, so they do not absorb water or allow for water stagnation.
• The three Velcro straps give the shoe a perfect grip, while also changing the thickness of the shoes.
• The sole is made in Grivory thermoplastic by EMS with non-slip heels made inpolyurethane.
• The stiffness of these materials allows the diver to unload leg movement on the fins without wasting energy, giving you the highest level of performance.
• The sole also has drain channels on the inside, which allow for emptying of water after fishing, in order to avoid water stagnation or build-up of mold in the shoe.
• The vamp is connected to the sole through structural bonding. Moreover, in the front part of the shoe, where there is the most stress while swimming, the top part is connected to the sole by two rust-proof rivets.

REVOLUTION BLADE

• Removable and replaceable fin with high modulus polypropylene.
• The 26º angle of the fin, with respect to the axis of the sole, creates a push that is equal during down-kick and up-kick, limiting the area of standstill where there is no thrust.
• Five stabilizers have been inserted in the fin.
• The four lateral stabilizers, two on the upper part and two on the bottom, impede fin leeway during swimming.
• The central-upper stabilizer, moreover, while standing still during fishing, keeps the fin slightly off the sea floor and thus limits any lifting of sediments.
• The fin is connected to the shoe pocket through the use of three stainless steel M5 metric screws.
• It is available in two versions: in standard black or with the green camouflage finish.

Wszystko zaczęło się styczniowego popołudnia 2004 r. kiedy to na portalu “bigblueteam.com.pl” Andrzej Wiland natknął się na listę ludzi zainteresowanych freedivingiem. Jedną z osób, z którą udało mu się później skontaktować był Hubert Choma, który od początku deklarował chęć do wspólnego nurkowania. Kilka dni później Andrzej i Hubert spotkali się po raz pierwszy na basenie…

Freediving Team Warszawa stawał się coraz silniejszy, a jego członkowie zarażeni wspólną pasją do swobodnego nurkowania, z powodzeniem reprezentowali stolicę w zawodach basenowych i na wodach otwartych.

Od tego czasu skład zmieniał się wielokrotnie by na początku 2009 rok ukształtował się w zgraną paczkę kilku zapaleńców zafascynowanych pięknem tego sportu.

Time course of carbon monoxide transfer factor after breath-hold diving.
Undersea Hyperb Med. 2009 Mar-Apr;36(2):93-101

Breath-hold divers may experience haemoptysis during diving. Central pooling of blood as well as compression of pulmonary gas content can damage the integrity of the blood-gas barrier, resulting in alveolar hemorrhage. The single-breath carbon monoxide test (DL,CO) was used to investigate the blood-gas barrier following diving. The study population consisted of 30 divers recruited from a training course. DL,CO levels were measured before diving and at 2, 10 and 25 min after the last of a series of four dives to depths of 10, 15, 20 and 30 m. When compared to pre-diving values, DL,CO values increased significantly at 2 min following diving in all subjects except one. Thereafter values progressively decreased toward baseline at 10 and 25 min in all subjects but…

Cardiovascular regulation during apnea in elite divers.
Hypertension. 2009 Apr;53(4):719-24

Involuntary apnea during sleep elicits sustained arterial hypertension through sympathetic activation; however, little is known about voluntary apnea, particularly in elite athletes. Their physiological adjustments are largely unknown. We measured blood pressure, heart rate, hemoglobin oxygen saturation, muscle sympathetic nerve activity, and vascular resistance before and during maximal end-inspiratory breath holds in 20 elite divers and in 15 matched control subjects. At baseline, arterial pressure and heart rate were similar in both groups. Maximal apnea time was longer in divers (1.7+/-0.4 versus 3.9+/-1.1 minutes; P0.0001), and it was accompanied by marked oxygen desaturation (97.6+/-0.7% versus 77.6+/-13.9%; P5-fold greater muscle sympat…

The ability to hold your breath for long periods of time can come in handy whether you are a freediver, surfer, kayaker, or other water-sports enthusiast. One way to increase the maximum amount of time that you can hold your breath is through the use of breath hold tables. The Breath Hold app puts the power of breath hold table workouts conveniently on your iPhone or iPod Touch. At the very least, you will be able to impress your friends with how long you can hold your breath!

A personal blog full of thoughts ideas training and pictures. Lots of sharks!

The successor of the C4 Flap 80, with the anatomic Mustang footpockets, this time in signal yellow for high visibility and safety. New Variable Geometry Rails, new stronger carbon fiber, and shape optimized for apnea/freediving (not for spearfishing).

Developed specially for freediving (no spearfishing or fin-swimming). They are made with MEGAFORCE T700 carbon fiber, a new carbon fiber, 40% stronger than the old one. The water-rails are VGR type (Variable Geometry Rails). Anatomical footpoket right and left with adjustable cloosing in 5 differents sizes.
The footpoket and the water-rails are yellow, for high visibility and safety.

The DOL-Fin is the first monofin designed to incorporate a highly efficient low-area hydrofoil fin, which minimizes body pitching to allow use with SCUBA equipment. Compared to traditional fins, the DOL-Fin design provides greater efficiency and speed, as well as increased comfort and a reduction of leg cramps.

The original concept for the DOL-Fin began as an experiment to create a more efficient swimming fin for freedivers. The project was a complete success and the DOL-Fin went on to win its first award in the 1995 BF Goodrich Collegiate Inventors Program. Since then, it has been improved and has developed into a truly impressive diving fin for both SCUBA and freediving. The DOL-Fin uses a patented fin suspension system to provide automatic active control of the high-aspect ratio fin to deliver powerful and efficient diver propulsion approaching the fluidic perfection found in nature's designs. Don't settle for old-fashioned flexible flippers when you could be swimming with a DOL-Fin.

It is our great pleasure to invite you to the first Croatian freediving competition RAB DIVE OFF 2008.

The competition will take place in deep waters around island Rab with the depth limit to – 105 meters.
