Abstract
Background: Load-carrying is a ubiquitous activity in daily life, often performed asymmetrically with one hand. The biomechanics and kinesiology of asymmetrical load-carrying during walking have attracted considerable attention. The additional weight from carrying loads can impact movement and walking patterns, including joint angles, range of motion, muscle activation, and overall walking mechanics.
Aim: This systematic review aims to understand the specific changes in walking kinematics and kinetics resulting from load-carrying, with the goal of developing strategies to mitigate potential negative effects. Furthermore, this research is crucial for devising effective injury prevention and rehabilitation strategies.
Method: Comprehensive computerized literature searches were conducted in PubMed, Scopus, and Web of Science databases to identify articles related to load-carrying during walking. Participant characteristics, load-carrying conditions, study protocols, outcome measures, and main findings were extracted and qualitatively analyzed.
Results:
1. Kinematics: Load-carrying may induce alterations in joint angles in the lower extremities during different phases of the gait cycle. Specifically, investigations have examined changes in hip flexion/extension, knee flexion/extension, and ankle dorsiflexion/plantarflexion.
2. Kinetics: Increasing loads can lead to changes in joint torque, power, and ground reaction forces. These changes may encompass torque in the sagittal, frontal, and horizontal planes, as well as ground reaction forces in the vertical and horizontal planes.
Conclusions: The study of kinematics and kinetics in the context of asymmetrical load-carrying during gait provides valuable insights into the effects of weight-bearing activities on human movement patterns. Research demonstrates that load-carrying significantly alters joint angles and range of motion in the lower extremities, particularly during different phases of the gait cycle. Moreover, kinetic analysis indicates that increased loads can induce changes in joint torque, power, and ground reaction forces, consequently affecting the overall mechanics of walking. These findings underscore the importance of comprehending the biomechanics of load-carrying activities in daily life, as they hold significant implications for human health, safety, and performance. Future studies should further explore this area to unravel the intricate interplay between load-carrying and human movement dynamics.
