Influence Of Post-Exercise Nutrient Intake On Recovery And Subsequent Exercise Performance In Youth Cyclists, Andrew Law May 2019

Influence Of Post-Exercise Nutrient Intake On Recovery And Subsequent Exercise Performance In Youth Cyclists, Andrew Law

Masters Theses, 2010-2019

Purpose: The purpose of this study was to determine if chocolate milk (CM) consumption after high-intensity cycling exercise affects post-exercise recovery and subsequent exercise performance in youth cyclists, compared to a carbohydrate-only (CHO) and a placebo (PL) beverage. Methods: Eight youth cyclists (15-18 y, VO2peak = 61.8 ± 7.7 mL·kg-1·min-1) performed an exercise/recovery protocol consisting of 2 bouts of exercise, on 3 separate occasions, in a randomly counterbalanced crossover design. The first exercise bout (EX1) consisted of 30 min of constant-load cycling (40-60% Wmax), and 60 min of high-intensity intervals (alternating 2 min …

Does Acute Preprandial Exercise Modify Postprandial Inflammation After A High Fat Meal In Young And Older Adults?, William Wisseman

Masters Theses, 2010-2019

A single high-fat meal (HFM) can increase systemic inflammation (postprandial inflammation; PPI) and may be attenuated by recent exercise. However, the effect of preprandial exercise on PPI in older adults (OA) is not clear. Purpose: To determine if preprandial exercise attenuates PPI in YA and OA. Methods: 12 YA (23.3±3.9 years n= 5 M/7 F) and 12 OA (67.7±6 years, n= 8 M/4 F) completed two HFM challenges in a randomized order. During HFM alone, participants abstained from exercise 48 hours prior to the HFM session (except for the exercise session) and adhered to a 12 hour overnight …
