Effect of forward walking on cardiovascular parameters among the military

Introduction

The effect of forward walking on cardiovascular parameters among military personnel is a critical area of research, given the physical demands placed on soldiers during training and combat. This synthesis examines how forward walking, particularly under various conditions such as load carriage and hydration status, impacts cardiovascular health and performance in military settings.

Key Insights

Impact of Load Carriage on Heart Rate and Oxygen Uptake:
- Carrying heavier loads significantly increases heart rate and oxygen uptake, leading to greater physiological strain. Soldiers carrying loads of 22%, 44%, and 66% of their body mass experienced higher heart rates and oxygen uptake compared to carrying no load .
Hydration Status and Heart Rate:
- Hydration status plays a crucial role in managing heart rate during prolonged walking. Dehydrated soldiers exhibited significantly higher heart rates compared to their hydrated counterparts, indicating increased cardiovascular stress.
Walking Speed and Load Carriage:
- Heavier loads result in a significant decrease in walking speed. Soldiers carrying heavier loads (up to 66% of body mass) walked slower compared to those carrying lighter loads, suggesting that load carriage affects movement efficiency.
Posture and Gait Changes with Load:
- Increased load carriage alters soldiers' posture and gait, leading to greater forward trunk flexion and changes in knee and femur range of motion. These biomechanical adjustments are necessary to counterbalance the load but may increase the risk of musculoskeletal injuries.
Cardiovascular Function and Walking Training:
- Walking training at specific heart rate thresholds can improve cardiovascular function and autonomic regulation. This includes reductions in systolic and mean blood pressures, heart rate, and vascular resistance, as well as improvements in baroreflex sensitivity and walking capacity.

Conclusion

Forward walking, especially under conditions of load carriage and varying hydration status, significantly impacts cardiovascular parameters among military personnel. Heavier loads increase heart rate and oxygen uptake, reduce walking speed, and necessitate biomechanical adjustments that may lead to injury. Maintaining hydration is crucial to managing cardiovascular stress. Additionally, targeted walking training can enhance cardiovascular function and autonomic regulation, suggesting potential benefits for military training programs.

Overburdened soldiers experience severe impairments in walking speed when carrying recently developed military load-carrying equipment, suggesting that work intensity may be better described relative to heart rate rather than oxygen uptake.

Influence of carrying heavy loads on soldiers' posture, movements and gait

Carrying heavy loads in military load carriage systems alters soldiers' posture and gait, with the head and trunk working together to counterbalance the load, potentially leading to injury, muscle strain, and joint problems.
