    Stanford Report, August 29, 2012
    Stanford researchers' cooling glove 'better than steroids' – and helps solve physiological mystery, too

    The temperature-regulation research of Stanford biologists H. Craig Heller and Dennis Grahn has led to a device that rapidly cools body temperature, greatly improves exercise recovery, and could help explain why muscles get tired.

    The rapid thermal exchange device, nicknamed 'the glove,' creates a vacuum to draw blood to the surface of the palms. Cold circulating water cools the blood, which returns to the heart and rapidly lowers the body's core temperature.

    "Equal to or substantially better than steroids … and it's not illegal."

    This is the sort of claim you see in spam email subject lines, not in discussions of mammalian thermoregulation. Even the man making the statement, Stanford biology researcher Dennis Grahn, seems bemused. "We really stumbled on this by accident," he said. "We wanted to get a model for studying heat dissipation."

    But for more than a decade now, Grahn and biology Professor H. Craig Heller have been pursuing a serendipitous find: by taking advantage of specialized heat-transfer veins in the palms of hands, they can rapidly cool athletes' core temperatures – and dramatically improve exercise recovery and performance.

    The team is finally nearing a commercial version of their specialized heat extraction device, known as "the glove," and they've seen their share of media coverage. But what hasn't been discussed is why the glove works the way it does, and what that tells us about why our muscles become fatigued.

    Are you thinking what im thinking ?

    This is similar to the Core Control device. They are great for recovery and work best after exercise. Indeed, far better than anything on the market. They do not work well, however, for general cooling (veins are not open enough) and are not very portable. And they are very expensive. Not great for the average MSer, but if you work out hard at home, it could provide a huge boost.

      $3000.00 is the cost for that unit i think. That's alot for a beer can in a vacuum.

        Bench press study

        http://www.avacore.com/sites/default...-MSSE-2010.pdf

        ABSTRACT
        KWON, Y. S., R. A. ROBERGS, L. R. KRAVITZ, B. A. GURNEY, C. M. MERMIER, and S. M. SCHNEIDER. Palm Cooling Delays
        Fatigue during High-Intensity Bench Press Exercise. Med. Sci. Sports Exerc., Vol. 42, No. 8, pp. 1557–1565, 2010. Local cooling can
        induce an ergogenic effect during a short-term intense exercise. One proposed method of personal cooling involves heat extraction from
        the palm. Purpose: In this study, we hypothesized that local palm cooling (PC) during rest intervals between progressive weight
        training sets will increase total repetitions and exercise volume in resistance-trained subjects exercising in a thermoneutral (TN)
        environment. Methods: Sixteen male subjects (mean T SD; age = 26 T 6 yr, height = 178 T 7 cm, body mass = 81.5 T 11.3 kg, onerepetition
        maximum (1RM) bench press = 123.5 T 12.6 kg, weight training experience = 10 T 6 yr) performed four sets of 85% 1RM
        bench press exercise to fatigue, with 3-min rest intervals. Exercise trials were performed in a counterbalanced order for 3 d, separated by
        at least 3 d: TN, palm heating (PH), and PC. Heating and cooling were applied by placing the hand in a device called the rapid thermal
        exchanger, set to 45-C for heating or 10-C for cooling. This device heats or cools the palm while negative pressure (j35 to j45 mm Hg)
        is applied around the hand. Results: Total exercise volume during the four PC sets (2480 T 636 kg) was significantly higher than
        that during TN (1972 T 632 kg) and PH sets (2156 T 668 kg, P G 0.01). The RMS of the surface EMG with PC exercise was higher
        (P G 0.01), whereas esophageal temperature (P G 0.05) and RPE (P G 0.05) were lower during PC compared with TN and PH.
        Conclusions: PC from 35-C to 20-C temporarily overrides fatigue mechanism(s) during intense intermittent resistance exercise.
        The mechanisms for this ergogenic function remain unknown.
        (RTX Heating/Cooling Model No. 200962-006B; AVAcore,
        Inc., Palo Alto, CA). The RTX consists of a metallic cone
        heat exchanger surface on which the palm of the hand is
        placed and a plastic chamber that encloses the hand. A seal
        above the wrist maintains a vacuum around the hand. Air is
        pumped from the device, and negative pressure can be
        controlled and maintained. The circulating water temperature
        was maintained at 10-C during the cooling trials and
        at 45-C during the heating trials, and negative pressure
        was maintained at 45 mm Hg. The 10-C temperature was
        chosen based on previous research of hand immersion
        showing that this temperature is optimal and causes limited
        vasoconstriction in the hand.


        Does this seem that hard to make?
