• Kinematic stability in cardiac locomotor synchronization during regular walking

  Benio Kibushi

  In locomotion, previous studies have identified a phenomenon known as cardiac locomotor synchronization (CLS), characterized by the phenomenon where heartbeats consistently occur at a specific time within the locomotor cycle. While the physiological significance of CLS is well recognized, its kinematic benefits remain uncertain. Therefore, this study aimed to elucidate the kinematic benefits of CLS under regular walking. Smoothness of walking and local dynamic stability was assessed through the RMS of center of mass acceleration (RMS-CoM_acc) and maximum Lyapunov exponent (maxL). It was hypothesized that stronger CLS would lead to reduced RMS-CoM_acc and maxL. Thirteen participants performed a 10-minute walk at 5.0 km/h. The electrocardiogram and the motion capture data were recorded. To evaluate the CLS, phase coherence (λ) between cardiac and walking step rhythm was computed. The high and low-phase coherence was defined as λ ≥ 0.1 (λ_high) and λ < 0.01 (λ_low); corresponding RMS-CoM_acc and maxL values were compared for each state. Although the λ_high was significantly higher than λ_low, no significant differences in RMS-CoM_acc and maxL were observed between the high and low states. The relatively weak CLS observed herein might not have led to a reduction in RMS-CoM_acc and maxL. In addition, regular walking speed might be a velocity at which it is challenging to generate intervention effects. Hence, the CLS appears to have negligible impact on the smoothness of walking or local dynamical stability at a 5.0 km/h.

• Muscle synergies of multidirectional postural control in astronauts on Earth after a long-term stay in space.

  Movements of the human biological system have adapted to the physical environment under the 1-g gravitational force on Earth. However, the effects of microgravity in space on the underlying functional neuromuscular control behaviors remain poorly understood. Here, we aimed to elucidate the effects of prolonged exposure to a microgravity environment on the functional coordination of multiple muscle activities. The activities of 16 lower limb muscles of 5 astronauts who stayed in space for at least 3 mo were recorded while they maintained multidirectional postural control during bipedal standing. The coordinated activation patterns of groups of muscles, i.e., muscle synergies, were estimated from the muscle activation datasets using a factorization algorithm. The experiments were repeated a total of five times for each astronaut, once before and four times after spaceflight. The compositions of muscle synergies were altered, with a constant number of synergies, after long-term exposure to microgravity, and the extent of the changes was correlated with the increased velocity of postural sway. Furthermore, the muscle synergies extracted 3 mo after the return were similar in their activation profile but not in their muscle composition compared with those extracted in the preflight condition. These results suggest that the modularity in the neuromuscular system became reorganized to adapt to the microgravity environment and then possibly reoptimized to the new sensorimotor environment after the astronauts were reexposed to a gravitational force. It is expected that muscle synergies can be used as physiological markers of the status of astronauts with gravity-dependent change.NEW & NOTEWORTHY The human neuromuscular system has adapted to the gravitational environment on Earth. Here, we demonstrated that prolonged exposure to a microgravity environment in space changes the functional coordination of multiple muscle activities regarding multidirectional standing postural control. Furthermore, the amount of change led to a greater regulatory balancing activity needed for postural control immediately after returning to Earth and differences in muscular coordination before space flight and 3 mo after the return to Earth.

• Lower local dynamic stability and invariable orbital stability in the activation of muscle synergies in response to accelerated walking speeds

  Kibushi B, Hagio S, Moritani T, Kouzaki M

  In order to achieve flexible and smooth walking, we must accomplish subtasks (e. g., loading response, forward propulsion or swing initiation) within a gait cycle. To evaluate subtasks within a gait cycle, the analysis of muscle synergies may be effective. In the case of walking, extracted sets of muscle synergies characterize muscle patterns that relate to the subtasks within a gait cycle. Although previous studies have reported that the muscle synergies of individuals with disorders reflect impairments, a way to investigate the instability in the activations of muscle synergies themselves has not been proposed. Thus, we investigated the local dynamic stability and orbital stability of activations of muscle synergies across various walking speeds using maximum Lyapunov exponents and maximum Floquet multipliers. We revealed that the local dynamic stability in the activations decreased with accelerated walking speeds. Contrary to the local dynamic stability, the orbital stability of the activations was almost constant across walking speeds. In addition, the increasing rates of maximum Lyapunov exponents were different among the muscle synergies. Therefore, the local dynamic stability in the activations might depend on the requirement of motor output related to the subtasks within a gait cycle. We concluded that the local dynamic stability in the activation of muscle synergies decrease as walking speed accelerates. On the other hand, the orbital stability is sustained across broad walking speeds.
