TI  - "Train-High Sleep-Low" Dietary Periodization Does Not Alter Ventilatory 
      Strategies During Cycling Exercise.

AB  - Objective: The purpose of this study was to investigate the effects of 
      "train-high sleep-low" (THSL) dietary periodization on ventilatory strategies 
      during cycling exercise at submaximal and maximal intensities.Method: In a 
      randomized crossover design, 8 trained men [age (mean +/- SEM) = 28 +/- 1 y; peak 
      oxygen uptake = 56.8 +/- 2.4 mL kg(-1) min(-1)] completed two glycogen-depleting 
      protocols on a cycle ergometer on separate days, with the cycling followed by a 
      low carbohydrate (CHO) meal and beverages containing either no additional CHO 
      (THSL) or beverages containing 1.2 g kg(-1) CHO [traditional CHO replacement 
      (TRAD)]. The following morning, participants completed 4 minutes of cycling below 
      (Stage 1), at (Stage 2), and above (Stage 3) gas exchange threshold, followed by 
      a 5-km time trial.Results: Timetrial performance was significantly faster in TRAD 
      compared to THSL (8.7 +/- 0.3 minutes and 9.0 +/- 0.3 minutes, respectively; 
      p = 0.02). No differences in ventilation, tidal volume, or carbon dioxide 
      production occurred between conditions at any exercise intensity (p > 0.05). 
      During Stage 1, oxygen uptake was 37.9 +/- 1.5 mL kg(-1) min(-1) in the TRAD 
      condition and 39.6 +/- 1.8 mL kg(-1) min(-1) in THSL (p = 0.05). During Stage 2, 
      VO2 was 44.6 +/- 1.7 mL kg(-1) min(-1) in the TRAD condition and 47.0 +/- 1.9 mL 
      kg(-1) min(-1) in THSL (p = 0.07). No change in operating lung volume was 
      detected between dietary conditions (p > 0.05).Conclusions: THSL impairs 
      performance following the dietary intervention, but this occurs with no 
      alteration of ventilatory measures.
