Nineteen men (mean \u00b1 SD: age 19.9 \u00b1 2.6 years, height: 175.7 \u00b1 6.5 cm, body mass 80.3 \u00b1 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 \u2264 0.05. There was a significant difference in protein intake (g) between weeks 2 and 11 of BT (115 \u00b1 18 vs. 91 \u00b1 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 \u00b1 4.1 g, 6: 1.6 \u00b1 4.5 g, 11: \u22120.2 \u00b1 5.5 g, p = 0.07). A protein intake of 1.5 g\u00b7kg\u22121\u00b7d\u22121 may be sufficient in the early stages of BT, but higher intakes may be individually needed later on in BT.<\/jats:p>","DOI":"10.3390\/nu12072125","type":"journal-article","created":{"date-parts":[[2020,7,17]],"date-time":"2020-07-17T10:22:02Z","timestamp":1594981322000},"page":"2125","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Dietary Intake and Nitrogen Balance in British Army Infantry Recruits Undergoing Basic Training"],"prefix":"10.3390","volume":"12","author":[{"given":"Shaun","family":"Chapman","sequence":"first","affiliation":[{"name":"HQ Army Recruiting and Initial Training Command, UK Ministry of Defence, Upavon, Wiltshire SN9 6BE, UK"},{"name":"Cambridge Centre for Sport and Exercise Sciences, School of Psychology and Sport Science, Anglia Ruskin University, East Road, Cambridge CB1 1PT, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0942-7185","authenticated-orcid":false,"given":"Alex J.","family":"Rawcliffe","sequence":"additional","affiliation":[{"name":"HQ Army Recruiting and Initial Training Command, UK Ministry of Defence, Upavon, Wiltshire SN9 6BE, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Izard","sequence":"additional","affiliation":[{"name":"Defence Science and Technology, Porton Down, UK Ministry of Defence, Salisbury, Wiltshire SP4 0JQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kimberley","family":"Jacka","sequence":"additional","affiliation":[{"name":"HQ Army Recruiting and Initial Training Command, UK Ministry of Defence, Upavon, Wiltshire SN9 6BE, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hayley","family":"Tyson","sequence":"additional","affiliation":[{"name":"HQ Army Recruiting and Initial Training Command, UK Ministry of Defence, Upavon, Wiltshire SN9 6BE, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5340-9833","authenticated-orcid":false,"given":"Lee","family":"Smith","sequence":"additional","affiliation":[{"name":"Cambridge Centre for Sport and Exercise Sciences, School of Psychology and Sport Science, Anglia Ruskin University, East Road, Cambridge CB1 1PT, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3169-2041","authenticated-orcid":false,"given":"Justin","family":"Roberts","sequence":"additional","affiliation":[{"name":"Cambridge Centre for Sport and Exercise Sciences, School of Psychology and Sport Science, Anglia Ruskin University, East Road, Cambridge CB1 1PT, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2565","DOI":"10.1249\/MSS.0000000000001716","article-title":"Sex Differences in Training Loads during British Army Basic Training","volume":"50","author":"Saunders","year":"2018","journal-title":"Med.
