- - This study investigates the factors leading to attrition in a 10-week military training program for male and female candidates, analyzing data from 1006 participants who underwent various assessments including blood draws, questionnaires, and fitness tests.
- - Of the candidates, 260 (25.8%) left the program, with the highest dropout rate occurring in week 5, primarily due to musculoskeletal injuries (30%) and other medical or voluntary reasons.
- - Key predictors associated with attrition include sex, body mass index (BMI), resilience, and physical fitness test scores, with the final model highlighting combat fitness test scores and resilience as significant indicators, suggesting that these factors can aid early screening processes for candidates at risk of not completing the
Article Synopsis
- - The study aimed to explore how deficiencies in vitamin D and iron among Marine Officer Candidates could affect their skeletal health and risk of injuries during military training, assessing their micronutrient levels before and after 10 weeks of training.
- - Results indicated that micronutrient levels decreased after training, with those having optimal vitamin D and iron status showing better bone strength and lower injury risks compared to those with deficiencies.
- - The findings highlight the importance of maintaining adequate vitamin D and iron levels for improving readiness and reducing injury risks in military personnel during rigorous training.
Background: Arduous military training frequently consists of prolonged physical activity, sleep disturbance, and stress that increases musculoskeletal injury risk and performance decrements. Inflammatory and oxidative stress responses have been reported in response to arduous training, but with inconsistencies across markers and with underrepresentation of women. The purpose of the current report was to measure circulating inflammation and oxidative stress responses to military training and to correlate biomarkers with subjective measures of stress and sleep quality as well as military fitness test performance.

The purpose of this study was to determine the association between overuse MSKI occurrence and physiological characteristics of allostatic load characterized as maladaptive biological responses to chronic stress measured by wearable devices in US Marine Corps officer candidates during a 10-wk training course.
Methods: Devices recorded energy expenditure (EE), daytime heart rate (HR), sleeping HR, and sleep architecture (time and percentage of deep, light, rapid eye movement sleep, awake time, total sleep).
