AB  - This study examined the effects of whey and pea protein supplementation on 
      physiological adaptations following 8-weeks of high-intensity functional training 
      (HIFT). Fifteen HIFT men (n = 8; 38.6 +/- 12.7 y, 1.8 +/- 0.1 m, 87.7 +/- 15.8 kg) and 
      women (n = 7; 38.9 +/- 10.9 y, 1.7 +/- 0.10 m, 73.3 +/- 10.5 kg) participated in this 
      study. Participants completed an 8-week HIFT program consisting of 4 training 
      sessions per week. Participants consumed 24 g of either whey (n = 8) or pea (n = 
      7) protein before and after exercise on training days, and in-between meals on 
      non-training days. Before and after training, participants underwent 
      ultrasonography muscle thickness measurement, bioelectrical impedance analysis 
      (BIA), two benchmark WODs (workout of the day), 1-Repetition Maximum (1RM) squat 
      and deadlift testing, and Isometric Mid-thigh Pull (IMTP) performance. Separate 
      analyses of covariance (ANCOVA) were performed on all measures collected at POST. 
      Both groups experienced increased strength for 1RM back squat (p = 0.006) and 
      deadlift (p = 0.008). No training effect (p > 0.05) was found for body 
      composition, muscle thickness, IMTP peak force, IMTP rate of force development, 
      or performance in either WOD. Using PRE values as the covariate, there were no 
      group differences for any measured variable. We conclude that ingestion of whey 
      and pea protein produce similar outcomes in measurements of body composition, 
      muscle thickness, force production, WOD performance and strength following 
      8-weeks of HIFT.
