CYCLISTS WANTED FOR UCT RESEARCH DOES SLEEP DEPRIVATION IMPAIR EXERCISE RECOVERY? The aims of this study are (i) to describe the sleep habits of recreational male cyclists and to relate this to an aspect of their genetic makeup associated with preference for mornings or evenings, as well as sleep timing, and (ii) to compare individuals recovering from a single bout of high intensity interval training following either partial sleep deprivation or normal sleep. We are looking for trained recreational cyclists. If you: Are a male between 20 and 50 years of age Train at least three days per week for at least one hour per session Have a current Argus Cycle Tour time of under 03h45min You can volunteer for this study What is involved? Part A: Complete a questionnaire, donate cheek cell sample to determine your genetic variant for a gene linked to sleep behaviour, perform submaximal and maximal (VO2max) cycle tests. Part B: Have your performance, immune, inflammation and muscle damage responses measured in response to a single high intensity interval training session when you are either sleep deprived, or have had a normal night of sleep. What are the benefits? Personal and general feedback at the end of the study describing the sleep habits of recreational cyclists, as well the effect of sleep deprivation on exercise recovery. If you are interested in taking part in the study and would like additional information, please contact: Tayla Chin Kagiso Dikgomo taylachin@gmail.com kagiso.dikgomo@gmail.com 076 043 6795 074 121 0868
