Systematic cold weather training is essential for soldiers to best prepare to operate during, and recover from, cold weather operations. The purpose of this review is to highlight key aspects of cold weather training, including (1) human responses to cold, (2) nutrition, (3) sleep and (4) protective equipment requirements. Bringing science to practice to improve training principles can facilitate soldiers performing safely and effectively in the cold. Cold weather training prepares soldiers for operations in cold, harsh environments. However, decreases in physical, psychological and thermoregulatory performance have been reported following such training, which influences operational ability and increases the overall risk of injuries. When optimising the planning of field training exercises or operational missions, it is important to understand the soldiers' physical and cognitive performance capacity, as well as their capacity to cope and recover during and after the exercise or mission.

Physiological and biomechanical data can help illuminate the relationship between load carriage and injuries for service members. This review highlights characteristics that affect load carriage performance and summarises novel approaches to evaluate associated biomechanical changes. Personal characteristics, such as physical fitness and body composition, are good predictors of injury risk and load carriage ability. Effective training programmes can improve load carriage ability by altering fitness and body composition; however, careful planning is needed to integrate training with regular duties to prevent overtraining and, consequently, reduce injury risk in service members. Recent research supports the need for sex-specific training programmes since men and women achieve different training outcomes from similar stimuli. To further minimise injury risk, it is necessary to consider the effects of equipment characteristics (eg, load distribution, form and comfort) on physiological and biomechanical responses. Moreover, novel approaches to evaluate the effects of the various characteristics on load carriage performance are summarised in this review. Markerless motion capture and inertial measurement units have recently been used to evaluate kinematic changes while wearing various combat ensembles. Musculoskeletal modelling can complement kinematic analyses by evaluating internal joint mechanics during dynamic movements. By using frameworks that can leverage modelling approaches in real-time, service members can receive data-driven biofeedback on their load carriage performance and understand the loading experienced by their tissues to ultimately help mitigate their injury risks.</p>","PeriodicalId":48485,"journal":{"name":"Bmj Military Health","volume":" ","pages":"458-462"},"PeriodicalIF":1.7,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144128956","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}

Effective evidence-based intervention strategies are essential to reduce MSKI incidence, and research has shown the positive effect of both nutritional interventions and physical training (PT) interventions on reducing MSKI incidence. Levels of vitamin D metabolites have been associated with MSKI and bone stress fracture risk, while calcium and vitamin D supplementation has been shown to reduce the incidence of stress fractures during military training. Protein and carbohydrate supplementation during arduous military training (high volume, high intensity) has also been shown to reduce MSKI risk and the number of limited/missed duty days. PT has played a key role in soldier development to meet the occupational demands of serving in the armed forces. Paradoxically, while PT is fundamental to enhancing soldier readiness, PT can also be a major contributor to MSKI; emerging evidence suggests that the nature of the PT being performed is a risk factor for MSKI. However, strategies like reducing training load and implementing PT programmes using evidence-based training principles can reduce MSKI incidence among military service members by 33-62%, and reduce the financial burdens for military services.
