      Basic Training.

AB  - We assessed dietary intake and nitrogen balance during 14 weeks of Basic Training 
      (BT) in British Army Infantry recruits. Nineteen men (mean +/- SD: age 19.9 +/- 2.6 
      years, height: 175.7 +/- 6.5 cm, body mass 80.3 +/- 10.1 kg) at the Infantry Training 
      Centre, Catterick (ITC(C)) volunteered. Nutrient intakes and 24-h urinary 
      nitrogen balance were assessed in weeks 2, 6 and 11 of BT. Nutrient intake was 
      assessed using researcher-led weighed food records and food diaries, and 
      Nutritics professional dietary software. Data were compared between weeks using a 
      repeated-measures analysis of variance (ANOVA) with statistical significance set 
      at p </= 0.05. There was a significant difference in protein intake (g) between 
      weeks 2 and 11 of BT (115 +/- 18 vs. 91 +/- 20 g, p = 0.02, ES = 1.26). There was no 
      significant difference in mean absolute daily energy (p = 0.44), fat (p = 0.79) 
      or carbohydrate (CHO) intake (p = 0.06) between weeks. Nitrogen balance was 
      maintained in weeks 2, 6 and 11, but declined throughout BT (2: 4.6 +/- 4.1 g, 6: 
      1.6 +/- 4.5 g, 11: -0.2 +/- 5.5 g, p = 0.07). A protein intake of 1.5 g.kg(-1).d(-1) 
      may be sufficient in the early stages of BT, but higher intakes may be 
      individually needed later on in BT.
