Specifically, the study will evaluate the change in IML following a 2-hour training run and the recovery of IML in response to the post-exercise low-fat or moderate-fat diet in 10 endurance trained athletes who will consume both diets in a randomly assigned cross-over fashion. We hypothesize that IML will be depleted with prolonged endurance exercise, and that replenishment of IML will be impaired by an extremely low-fat diet compared to a moderate-fat diet. Results of this pilot study will be used to apply for extramural grant support from NIH or the US Armed Forces to investigate the effect of dietary fat on the health and performance of individuals performing heavy physical training. It is anticipated that this methodology could also be employed in obesity research to delineate, longitudinally, the reported cross-sectional relationships among IML stores, insulin resistance and obesity."}, "EligibilityModule"=>{"Gender"=>"All", "MaximumAge"=>"49 years", "MinimumAge"=>"18 years", "StdAgeList"=>{"StdAge"=>["Adult"]}, "HealthyVolunteers"=>"Accepts Healthy Volunteers", "EligibilityCriteria"=>"Inclusion Criteria:\n\nHealthy volunteers (developmental phase)\nHealthy endurance-trained subjects\nMaximum age for males is 39\nMaximum age for females is 49"}, "IdentificationModule"=>{"NCTId"=>"NCT00000110", "BriefTitle"=>"Influence of Diet and Endurance Running on Intramuscular Lipids Measured at 4.1 TESLA", "Organization"=>{"OrgClass"=>"NIH", "OrgFullName"=>"National Center for Research Resources (NCRR)"}, "OrgStudyIdInfo"=>{"OrgStudyId"=>"NCRR-M01RR00032-0855"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"M01RR000032", "SecondaryIdLink"=>"https://reporter.nih.gov/quickSearch/M01RR000032", "SecondaryIdType"=>"U.S. NIH Grant/Contract"}]}}, "ArmsInterventionsModule"=>{"InterventionList"=>{"Intervention"=>[{"InterventionName"=>"magnetic resonance spectroscopy", "InterventionType"=>"Procedure"}, {"InterventionName"=>"dietary fat", "InterventionType"=>"Drug"}]}}, "ContactsLocationsModule"=>{"LocationList"=>{"Location"=>[{"LocationZip"=>"35294", "LocationCity"=>"Birmingham", "LocationState"=>"Alabama", "LocationCountry"=>"United States", "LocationFacility"=>"The University of Alabama at Birmingham Nutrition Sciences Department"}]}}, "SponsorCollaboratorsModule"=>{"LeadSponsor"=>{"LeadSponsorName"=>"National Center for Research Resources (NCRR)", "LeadSponsorClass"=>"NIH"}}}}}}
