Serving Breakfast All Day- Post Exercise Recovery Research

October 29, 2009

P1010189 Pass the electrolyte aisle and proceed to the cereal aisle for your next post-exercise recovery meal. The Journal of International Society of Sports Nutrition printed a research article this past May comparing a carbohydrate-electrolyte sports drink with whole grain cereal and nonfat milk in their effectiveness of recovery. They used a small sample size of 12 trained cyclists and triathletes performing two hours of cycling at 60-65% maximum oxygen uptake. Post exercise, they consumed either a sports drink or a bowl of cereal and nonfat milk. The researchers took a muscle biopsy from the lateral quadriceps muscle immediately after exercise (and before the drink or cereal) and then again 1 hour after the drink or cereal to determine muscle glycogen synthesis. In addition to the biopsy, blood was also drawn at the end of exercise, and then at 15 min, 30 min, and 60 min post exercise to test for other recovery markers. Results: • Both the drink and cereal raised muscle glycogen (although not significantly differently between the two) one hour after exercise. • Blood insulin was significantly higher after consumption of the cereal and milk versus the sports drink. • mTOR, a muscle signaling protein, was significantly elevated after consumption of the cereal and milk, but not the sports drink. mTOR is known to aid in muscle growth and repair and initiate protein synthesis. Of course, more research is needed with a bigger sample size, different sports and various exertions. However, if you are cycling at 60-65% maximum oxygen uptake for two hours, you may want to try having a second breakfast to aid in your recovery. J Int Soc Sports Nutr. 2009 May 14; 6(1):11

What is Kinesiotaping?

KinesioTape1 What is Kinesiotape? By Johanna Lelke, DC, ART Have you heard of Kinesio® taping? There’s a good chance that you have seen it on pro athletes, maybe unaware that it’s any different than traditional white sports tape except for its fancy blue, black, pink, or flesh colors. Kinesio® tape has been used in the sports realm for over a decade, but wider use came during the Bejjing Olympics when my own teacher and mentor, Dr. Ted Forcum of Portland, applied some tape to Kerri Walsh’s shoulder to keep her playing strongly in spite of her injury. Chiropractors are one of several professionals who use “k-tape”, as it is otherwise known, on their patients and report huge therapeutic and performance benefits. Back strains in gymnasts, knee sprains, neck and upper back tension in cyclists, plantar fasciitis, leg strains in runners, and tennis elbow in climbers are just a few conditions in which I’ve found k-tape to work extremely well. What exactly does Kinesio® tape do? Many things. Depending on how it is applied, k-tape holds tension over a muscle that is partially torn, promotes lymphatic drainage in area that is swollen, supports the movement of irritated tendons, and prevents excessive movement at an injured joint. These functions, and others, are accomplished while still allowing near full range of motion. This is a key distinction from white sports tape which limits range of motion. More recently, certain applications of k-tape have been used to increase the kinetic potential in sports-specific muscle groups like quads for cyclists, rotator cuff for overhead throwing athletes and hamstrings for runners. The options are endless when considering how to fine-tune muscle movement for performance enhancement. Scientifically, only a few research papers on k-taping have been published. Clinically, increasing numbers of PTs, OTs, ATCs, DCs, MDs, LaCs, MTs and RNs have been using k-tape methods with success. Sufficiently high-caliber randomized, controlled research trials are expensive to conduct and therefore have not been funded and executed to date. How can you get some? At Innersport, we use k-tape on a regular basis for certain conditions. You will see how we apply it for your specific condition, then we can re-apply it during your office visits as needed (it usually stays on your skin for 2-4 days before peeling at the edges). Also, we can show you how to apply it at home. You can purchase it from several websites for about $14 per roll. Kinesio® is the original brand that researched and developed the method of taping. Other brands now exist, like KT Tape and Rock Tape, which are very similar.
