The study aimed to examine the relationship between cardiorespiratory fitness, stress response, cognitive function and military performance during prolonged military exercise.</p><p><strong>Methods: </strong>66 army cadets were included in the study. The subjects participated in a 4.5-day military winter training in northern Sweden. Maximal oxygen uptake (VO₂max) was estimated from a cycle test. Cognitive tests (design fluency, DF test) and measurements of heart rate variability (HRV) were conducted before and after the exercise. Assessment of military performance as an individual soldier (P-ind) and performance as a team leader (P-lead) was carried out during the final day of the exercise. Pearson's coefficient of correlation (<i>r</i>) and Spearman's rho were used to evaluate correlations, and linear regressions were used to examine the relationships between VO₂max, HRV, DF test scores and military performance. Simple mediation analyses were performed with DF test scores and military performance (P-ind, P-lead) as dependent variables, VO₂max as a predictor and HRV as a mediator.</p><p><strong>Results: </strong>Post-exercise HRV was related to military performance (P-ind: <i>r=</i>0.40, p<i><</i>0.01; P-lead: <i>r=</i>0.32, p<0.05). Absolute VO₂max was positively correlated with P-ind (<i>r</i>=0.28, p<0.05), and the effect of VO₂max on military performance was mediated by HRV.

These proteins are under the control of genes. The study of these genes and the interplay between multiple genes is pharmacogenomics, with individual genes being termed pharmacogenes. The greatest understanding of pharmacogenetics is of the drug metabolising enzymes, the cytochrome P450s. Almost the entire UK population is likely to have at least one genetic variant that controls these P450s and thus the phenotype for metabolic competence. This means two patients receiving the same medication and dose may have very different responses, from adverse reaction to being ineffective. An individual military person's response to medications can be predicted from their pharmacogenetics, as an example; the response to the commonly prescribed 'pain killers', codeine, tramadol, hydrocodone or oxycodone. These opioids are metabolised into their active forms by the cytochrome 2D6. Four phenotypes classify an individual's metabolic competency: ultra-rapid, extensive, intermediate or poor. A poor metaboliser is at risk of ineffective pain relief from one of the opioids listed, whereas an ultra-rapid metaboliser is at risk of overexposure and subsequent dependency or abuse. In white European populations, the prevalence of the phenotypes is well known and may be used to guide prescribing; however, in other populations such as Nepalese or Pacific Islander the distribution of these phenotypes is unknown. Genotyping provides a framework for the precise treatment of patients and cost-effective use of medication for the UK Armed Forces, as well as potentially providing equity for minority groups.</p>","PeriodicalId":48485,"journal":{"name":"Bmj Military Health","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142056978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
