This review article examines the physical attributes related to performance of essential military tasks like load carriage, manual material handling and casualty evacuation. It also discusses physical training intervention studies in military settings to enhance performance in these tasks. The results highlight the importance of muscular fitness in successfully completing these military tasks and suggest that combining strength, aerobic, and specific load carriage training may be an effective way to improve performance.
Physically demanding essential military tasks include load carriage, manual material handling and casualty evacuation. This narrative review characterizes the main physical attributes related to performance of these occupational tasks and reviews physical training intervention studies in military settings to improve performance in these military tasks. Load carriage performance requires both aerobic and neuromuscular fitness with greater emphasis on maximal strength and absolute maximal oxygen uptake, especially when carrying heavier loads. In manual material handling, maximal strength and power are strongly associated with discrete lifting, while muscular strength, muscular endurance and aerobic fitness are also associated with repetitive lifting performance. Maximal strength including grip strength, muscular endurance, absolute maximal oxygen uptake and anaerobic capacity are associated with casualty evacuation performance. The results of the present review particularly emphasize the role of muscular fitness in successful performance of the reviewed military occupational tasks. Training intervention studies indicate that load carriage performance can be effectively improved by combining strength, aerobic and specific load carriage training. Improvement in maximal lifting capacity can be achieved by strength training or combined strength and aerobic training, while strength and aerobic training alone, or their combination are effective in improving repetitive lifting, and carry tasks. Only a few studies are available for casualty evacuation and the results are inconclusive but may indicate benefits of strength or combined training. Moreover, emphasis on lower volume but higher intensity in combined training may be a feasible and effective mode to improve military occupational performance in recruits and active-duty soldiers.

Summary: This study examined the role of individual differences in baseline sleep on baseline physical performance and on changes in physical performance during exposure to simulated military operational stress. The results suggest that higher daytime sleepiness and slow wave activity may reflect more chronic exposure to insufficient sleep and higher baseline sleep drive, which in turn compromise physical performance.

Summary: Optimal motor control in gait variability is crucial for stable and adaptable movement. Load carriage and forced-marching are common perturbations that affect gait and are associated with a high incidence of musculoskeletal injuries in military populations. This study investigated the effects of load magnitude, locomotion pattern, sex, and task duration on motor variability, stride regulation, and spatiotemporal complexity during gait in recruit-aged adults.

Associations of serum 25(OH)D levels with physical performance and anabolic hormones in young men

Akseli Laaksi, Ilkka Laaksi, Harri Pihlajamaki, Jani P. Vaara, Tiina Luukkaala, Heikki Kyrolainen

Summary: The present study examined the association of serum 25(OH)D levels with physical performance outcomes and serum levels of anabolic hormones in young men. The results showed a positive association between serum 25(OH)D levels and both aerobic and muscular fitness. Participants with sufficient levels of vitamin D also had higher levels of testosterone. Maintaining a sufficient serum 25(OH)D level may have beneficial effects on physical performance and anabolic state in young men.

Summary: This intervention study examined the effects of low-intensity and high-intensity endurance training on durability. The results showed that both types of training improved durability by reducing physiological drifts and delaying their onset, as well as by changing physiological strain. However, these improvements may not be significant for untrained individuals.

Physiological and physical performance changes during a 20-day winter military training course and its subsequent 10-day recovery period

Tommi Ojanen, Kai Pihlainen, Jani P. Vaara, Heikki Kyrolainen

Summary: The present study examined the changes in physiological, mental, and physical performance during a 20-day winter military training course and the subsequent 10-day recovery period. The study included 58 male soldiers who underwent measurements of body composition, serum biomarker levels, and performance tests. The results showed significant declines in body and fat mass, physical performance variables, testosterone, and IGF-1 concentrations, while sex hormone-binding globulin, creatine kinase, and C-reactive protein values increased. Although some physical performance variables returned to baseline after the recovery period, explosive force production in the upper and lower bodies remained unrecovered.

A systematic review of HRV during diving in very cold water

Richard Viking Lundell, Tommi Ojanen

Summary: Heart rate variability (HRV) is a useful method to study the autonomic nervous system (ANS) status. This study aimed to review the human ANS responses in cold water diving and summarize the existing knowledge of HRV studies in diving and hyperbaric exposure. A literature search identified 26 articles meeting the criteria, suggesting that cold water strengthens the ANS responses of diving, particularly parasympathetic nervous system (PNS) activity. Cold and pressure-induced centralization of blood play a role in this response, with predominant PNS activity observed during water immersion and increased ambient pressure.
