Spraying L-menthol does not enhance running performance in the heat (research article)

L-Menthol stimulates cutaneous thermoreceptors and induces cool sensations improving thermal comfort but has also been linked to heat storage responses. Therefore, L-Menthol application could lead to a conflict in behavioural and thermoregulatory drivers improving comfort but leading to a higher rate of deep body temperature rise; the present study examined this possibility. That is from the study Spraying … Continue reading  Spraying L-menthol does not enhance running performance in the heat (research article)

Running Misfits

Can "Crossfit logic" meet running? Try this: 4 x 800 meters at threshold, 2 minutes recovery 400 meters all-out, 2 minutes recovery 300 all-out, 2 minutes recovery 200 all-out, 2 minutes recovery What's that all about? If you’re wondering what sets Track Mafia apart from all the other running crews out there (TM is actually an off-shoot … Continue reading Running Misfits

Save time with short, intense sprints (Research Study)

Little Byte Summary: Short sprints at timed intervals can help you get the same health benefits in less time than longer-duration exercise sessions. Researchers in Norway conducted a small study comparing 12 weeks of a medium-intensity, 50 minute, cycling workout with  a 3x20 second "max" sprint workout  (1 minute total), in which the sprints were interspersed … Continue reading Save time with short, intense sprints (Research Study)

The Effects of Ketogenic Dieting on Body Composition, Strength, Power

Little Byte Summary: Male athletes on a ketogenic diet observed body composition and testosterone changes compared to a control group on a different diet. Altering dietary carbohydrate intake seems to have a profound impact on mass and blood profiles in this group. Background: We recently mentioned Prof. Jeff Volek and some ketogenic products in a … Continue reading The Effects of Ketogenic Dieting on Body Composition, Strength, Power

Actins: the “sprinter” gene family has multiple isoforms

If you have had any genetic tests, you've probably come across the "sprinter gene", or Actin. Here is a paper showing that there are multiple actins, each with small differences in amino acid structure. These include cariac-, smooth-, and muscle- isoforms. Interestingly, small differences can lead to different function: Although actin is often thought of … Continue reading Actins: the “sprinter” gene family has multiple isoforms
