You will first ride on a cycle ergometer at the sports science institute in Cape Town with your own bike attached so we can determine your PPO, followed by an established cycling exercise protocol to deplete your muscle glycogen. You will then have to follow a 3 day low carb diet, (we'll give you a the diet plan) plus you'll get sports drinks from us which you will have to drink over these 3 days. These drinks will either be a high carb drink or a low carb drink, but you won't know which drink you'll receive when because the drinks look and taste the same ie: you are so-called 'blinded' to the intervention. Those participants that receive the high carb drink will increase their muscle glycogen levels, where the others will stay low - we know this to be true based on and confirmed by lots of previous research. You will then come back to the lab for the actual data collection ie: you'll ride a 15min steady state at 70% PPO, followed by a 40km time trial performance ride, followed by another 15min steady state ride. During this ride i will have to measure your blood glucose concentration via the finger prick test as used by diabetics 5 times. I will also ask you at certain intervals to give me your Rating of Perceived Exertion, based on the validated Borg Scale (we will explain the scale during your first session ie PPO/depletion ride). And then we need to repeat this whole test ie: the depletion ride, followed by the 3 days of low carb diet and drinks, followed by the performance ride approximately 4 weeks later. So each participant serves as his own control ie comparing apples to apples. If you had the high carb drink in the first round, you'll get the low carb drink in the 2nd round and v.v. But you won't know when you get what. After the data analysis, we'll know how the different muscle glycogen concentrations affect your performance and perception of effort/fatigue.

Dear fellow HubSA members, The MRC/UCT Research Unit for Exercise Science and Sports Medicine is conducting a study to investigate the psychophysiological determinants of pacing during prolonged endurance. The aim of the study is to determine the physical and mental factors that make up the High Performance Athlete. The study will investigate the differences between 'Elite' and 'Sub-Elite' cyclists as well as the differences between the 'Winners' and 'Losers' of a simulated head-on-head competition on a virtual hilly 70km time trial course. Eligibility criteria are: Male Age 18-45 'Elite' cyclists: Sub-3 hours Cape Argus,>8h per week, and if available a PPO of 5.3 to 5.7 W/kg and a VO2max of >60 ml/min/kg 'Sub-Elite' cyclists: 3:15 to 3:30 Cape Argus, 6-8h per week, and if available a PPO of 4.5 to 4.9 W/kg and a VO2max of >55 ml/min/kg Requirements are: 4 visits to the Sports Science Institute of South Africa, Newlands, Cape Town in the next 6 to 8 weeks Visit 1: 3.5-4h, incl. Anthropometry, VO2max testing and 70km Familiarization Visit 2: 2.5-3h, maximal 70km Baseline Time Trial Visit 3: 3-3.5h, maximal 70km Individual Time Trial, incl. questionnaires and blood sampling Visit 4: 3-3.5h, maximal 70km Competition Time Trial against an equally matched cyclist, incl. questionnaires and blood sampling Benefits are: A full and comprehensive VO2max Report Spin Scan analysis of your two Experimental Time Trials A Psychological Performance Profile For more Information see Research Posters attached and/or contact: Dr. Andreas Venhorst, MD andreas.venhorst@gmail.com We are looking forward to having you as a participant!

Just a quick thank-you to City Cycling Club for organizing a great 2 man Team Time Trial at Fisantekraal today. Heading out this morning, the weather could not have been any better. It was a beautiful sunny morning with a gentle 4-7kmh wind from a westerly direction which makes a very pleasant change from a howling south-easter. The race was billed as a 2 man team time trial over a fairly flat 25km circuit with only a few gentle rollers that weren't going to hurt too much. City Cycling Club was well represented as well as the Outriders and a couple of teams from Team Pure Savage and Complete Cyclist. As far as possible the lower seeded pairs started first with the quicker riders starting out last. With a 2 minute gap between the pairs there weren't too many teams passing each other and it worked very well. It was very obvious comparing the difference between the serious TT's on TT specific bikes and those on normal road bikes. The winning average was well over 40kmh.

Hey hubbers. I am doing my first full ironman this year. Yikes. I am keen to get a TT bike, but won't be able to prior to this years event. Was wondering whether there are any kind souls out there, who ride a 56cm TT bike and lives in Joburg who would be willing to let me ride their pride and joy Worth an ask Scrumpy
