Here is an interesting research idea funded by public Money. Just read and than compare with the ongoing discussion we have on using % of maximal performance on values of any further outcome. Take the case stduy we did with the 28 year old and the 55 year old. Take the wattage of the MAP and calculte 75 % of that . Remember 527 Watt ( 75 % ) and 400 watt 75 % and nnow here the Max watt in the FaCT 28 Year old 527 MAP 340 FaCT 55 year old 400 MAP and 360 FaCT 28 year old MAP ( 75% = 395 Watt ) FaCT ( 75 % = 255Watt still above LBP ) 55 year old MAP ( 75 % = 300 Watt ) FaCT ( 75 % = 270 watt ) Now here the publicliy funded research : This study will take place in Dr. Koehle's Laboratory in the Wesbrook Building at the University of British Columbia. Overview of the Study You will be requested to come to the laboratory on three occasions. The first visit will consist of a maximal incremental exercise test on a cycle ergometer (approximately 40 minutes). The remaining 2 days will consist of 2 time trials to exhaustion at 75% of your maximum power (achieved in day 1) separated by 3 hours of rest. During that rest time you wear either a shielded garment or a placebo garment. Whichever garment you did not wear on your first visit to the laboratory you will wear on the second visit. The order of placebo and shielded garment will be randomized. You will not know which garment you are wearing until after the study is complete. Questions like recovery , use of muscle fiber, Nutritional set up. Preparation to teh test and so on ? Interesting idea and for sure fun to work on. Have fun to think and you may see, why we have as well some "critical" ideas on values of many of our own and other so called research . Remember the warnig" by Sheppard and Bannnister , that an ARMY of researcher ( including us ) will do a million of "stduies" of very little value or as repetitions of already done studies for the sake of a paper ( Ph.D or a final work at an insitution. All this funded by public money. Don't get me wrong . I think any "study " has values for the people, who do the study , as durig thsi time we try to understand the practical applications and limitations testing equipment and information may have after the outcome. The bigger question is, whether it is up to the public to "sponsor" own interest and curious questions, or whether it is like a painter or singer. Have fun and hope somebody may like what you do. So have fun in the upcoming year to read some of our often fun but potentially worthless studies whcih have the one goal : Fun and test equipment on the value of using it in the field or as coaches and athletes for our own purpose and potential benefit. We welcome any positive critical discussion on any of our crazy ideas, as this is the only way we can go and search for further ideas and equipment , which may or may not be beneficial for health and sport activity. Have all a happy new year and I hope to see and hear from so many places from all over the globe again in 2009. Juerg for FaCT Canada. HAPPY NEW YEAR . | ||

Here the full research plan : " December 30/08 Noon EST - Elite Competitive Cyclists Needed for Research Study Posted by Editor on 12/30/08. ---------------------------------------- ---------------------------------------- Elite Competitive Cyclists Needed for Research Study Elite competitive cyclists or triathletes with no significant cardiac or respiratory health problems are invited to take part in a research study on recovery and the performance benefits of certain garments. BACKGROUND Recovery between competitions is a key to performance in multi-race events. The difference in performances between elite athletes is very small, so every potential advantage can make a key difference. Clothing that is designed to block electromagnetic radiation (such as radio waves, x-rays and microwaves) has been shown to decrease delayed onset muscle soreness after intense exercise. It therefore has the potential to enhance recovery over the medium term. The purpose of this study is to look at short term recovery between repeated simulated competitions to assess for a performance benefit of this type of garment. WHO CAN PARTICIPATE IN THE STUDY? To participate, you must be a male category 1-2 cyclist (or equivalent) or a triathlete capable of performing a 40 km time trial in less than 60 minutes. You must be free of heart or respiratory disease, and must be a nonsmoker. You must between the ages of 19 and 40. WHAT IS THE PURPOSE OF THE STUDY? The purpose of this study is to determine whether there is a benefit of wearing a shielded garment in two repeated maximal cycling efforts separated by 3 hours. WHAT ARE THE BENEFITS OF PARTICIPATING IN THIS STUDY? We will be able to provide you with information pertaining to your maximum power output, as well as heart rates at various workloads during exercise. We hope that the information learned from this study can be used in the future to benefit competitive athletes and exercisers hoping to improve their recovery from exercise. You will also receive an honorarium for your participation. WHAT DOES THE STUDY INVOLVE? This study will take place in Dr. Koehle's Laboratory in the Wesbrook Building at the University of British Columbia. Overview of the Study You will be requested to come to the laboratory on three occasions. The first visit will consist of a maximal incremental exercise test on a cycle ergometer (approximately 40 minutes). The remaining 2 days will consist of 2 time trials to exhaustion at 75% of your maximum power (achieved in day 1) separated by 3 hours of rest. During that rest time you wear either a shielded garment or a placebo garment. Whichever garment you did not wear on your first visit to the laboratory you will wear on the second visit. The order of placebo and shielded garment will be randomized. You will not know which garment you are wearing until after the study is complete.

Here some short background information: 1." Clothing that is designed to block electromagnetic radiation (such as radio waves, x-rays and microwaves) has been shown to decrease delayed onset muscle soreness after intense exercise" DOMS = delayed onset muscle soreness. This definition, based on Dr. Alan Donnelly's information ( Senior lecturer , Department of Physical Education and Sport science , University of Limerick , Limerick Ireland ). " Exercise including ECCENTRIC muscle contraction, where the muscle lenghtens as it produces force, is associated with DOMS, or muscle stiffness. Running, particular downhill, is a common cause of DOMS." First Question: DOMS and cycling ? Cycling and eccentric ? " Unaccustomed exercise. Temporary muscle soreness can occur during the final stage of a high exercise bouts, probably as a result of metabolite accumulation. This receeds on cessation of exercise. In Contrast, DOMS is characterized by its late onset, most commonly one day after unaccustomedexercise and with maximum soreness occuring two or three days after exercise. Muscle soreness is felt when the limb is moved or on palpation and declines completely between five and nine days after exercise. The precise mechanisme by which muscle soreness arises is not clear, although monocyte-derived prostagladines and tissue oedema have been proposed as causative factor." Question 2 : Unaccustomed exercise.(DOMS) "Elite Competitive Cyclists Needed for Research Study" 3: DOMS is characterized by its late onset, most commonly one day after unaccustomed exercise. The remaining 2 days will consist of 2 time trials to exhaustion at 75% of your maximum power (achieved in day 1) separated by 3 hours of rest. During that rest time you wear either a shielded garment or a placebo garment. Question: How many Elite cyclists will or experience a DOMS after a TT of 75 % to exhaustion and what is the definition of exhaustion ? Example: In the 2 case stduies from the Top: Athlete 28 year old actually will bike potetially 2 - 5 min if we use 75 % of the MAP test. When we use the FaCT 3 min step test he will potentilly bike 30 - 60 min as it is still above LBP ( or FTP) The 55 year old will if using MAP 75 % bike for 30 min on 300 watt and more motivational limitation and food ( glucose ) limitation on the Step test 75 %. Now if in the step test to exhaustion the motivation is high htan the second part will be short and fast over. If one or the other athlte does not push all out the second part could be a long way to go. So the "fatigue " in the second part with the rest of three hours will have a lot of variabilities on the part of recovery and it will be very interesting to see, how they can quantify , what was changing the recovery, as well whether the second time arround the 2 tests with the 3 hours rest is really a good way to assess a recovery unit like they try to assess. What are your thoughts ? |
