  Purpose

This study compared the acute effect of ingesting bananas (BAN) versus a 6% carbohydrate drink (CHO) on 75-km cycling performance and post-exercise inflammation, oxidative stress, and innate immune function using traditional and metabolomics-based profiling.

Primary Outcome Measures:
  • Performance and fuel substrate utilization as measured through metabolomics [ Time Frame: Up to 6 months ] [ Designated as safety issue: No ]
    Will measure shifts in metabolites following 75-km cycling while ingesting bananas or 6% carbohydrate beverage. The shift in metabolites will be assessed using GC-MS. Time frame from date of randomization until the last samples are collected and analyzed will be up to six months.


Secondary Outcome Measures:
  • Exercise-induced inflammation. [ Time Frame: up to 6 months ] [ Designated as safety issue: No ]
    Cytokine panel (IL-6, IL-8, IL-10, TNF-alpha) before and after cycling 75-km; measured with Meso Scale Discovery in pg/ml. Time frame from randomization until the last samples are collected and analyzed will be up to six months.

Arms Assigned Interventions
Experimental: Bananas versus 6% carbohydrate beverage Dietary Supplement: Bananas versus 6% carbohydrate beverage
Trained cyclists (N=14) completed two 75-km cycling time trials (randomized, crossover) while ingesting BAN or CHO (0.2 g/kg carbohydrate every 15 min).
Other Name: Gatorade

Detailed Description:

Trained cyclists (N=14) completed two 75-km cycling time trials (randomized, crossover) while ingesting BAN or CHO (0.2 g/kg carbohydrate every 15 min). Pre-, post-, and 1-h-post-exercise blood samples were analyzed for glucose, granulocyte (GR) and monocyte (MO) phagocytosis (PHAG) and oxidative burst activity, nine cytokines, F2-isoprostanes, ferric reducing ability of plasma (FRAP), and metabolic profiles using gas chromatography-mass spectrometry.
