“…The choice of the interval SRC mode is due to the better subjective tolerance of intermittent exposurewith a shorter exposure subjects note less discomfort caused by prolonged leg strain during overload. Moreover, in real SF, the comparative analysis of various modes of locomotor training showed higher preventive effectiveness of interval training compared to continuous workouts (Fomina et al 2016).…”

Short-radius centrifugation (SRC) is a promising and economically feasible countermeasure in space ight and applies to gravity therapy in terrestrial medicine. The potential occurrence of undesirable orthostatic and vestibular reactions limits the use of this method. One way to minimize these risks is the ability of a human to adapt to the effects of overload. It is known that arti cial gravity training may improve orthostatic tolerance. New data demonstrated that cardio-postural interactions and musclepump barore ex activation are present during short-arm centrifugation. Based on previous studies, we hypothesized that repeated SRC in the interval training mode with angular velocities from 22 to 28 rpm may also improve postural tolerance. Six healthy male volunteers were observed before and immediately after ve consecutive SRC sessions. The rest between SRC was at least three days. The SRC mode was an interval and included ve 300-second platforms with 1.27 g at the feet and four 300-second platforms with 2.06 g at the feet. We registered the main postural characteristics and ground reaction forces data when the participant kept the center of pressure at a given point in a standing position with biofeedback and without this. After the rst SRC session, there was a signi cant posture decondition. The SRC training effect was already noticeable after the second SRC session and was stable until the end of the experiment. The results demonstrate the development of postural tolerance to arti cial gravity exposure in this mode and expand the understanding of sensorimotor adaptation capabilities.

“…When the COG moved, a quick return establishes a solid foundation of support beneath the COG, or additional external support is required to stop someone from falling. The definition of balance changes when a person moves more quickly because the momentum of their bodily movement must also be considered [8,9].…”

Balance is the ability to move and/or preserve a particular position while not falling under external force. Human balance is a complex process of integration and coordination of the sensory, motor, and biomechanical components, which is influenced by intrinsic and exogenous factors. One inherent factor that is hypothesized to have an impact on balance is cognition. However, studies about cognition's role in balance control are still limited, and study literature is needed to gain a better understanding. Cognition is involved in various thinking processes. Attention, memory, visuospatial, and executive functions are among the cognitive areas integrated with information processing in the processing of information, followed by a reaction that aims to preserve body balance and prevent falls. Cognition limitation has been linked to decreased function associated with gait alterations, mobility limitation, and increased risk of falling. Cognitive function impairments such as executive function (EF) limitations are thought to increase the risk of losing. Injury to the cerebral cortex, basal ganglia, and cerebellum can also affect the cognitive function in balance. The role of cognition in maintaining physical balance is critical. Deficits in cognitive function caused by diseases or injuries will impact bodily balance control.

“…Countermeasures against functional and structural changes in skeletal muscles caused by gravitational unloading play an important role in the medical support of manned space flights. Numerous studies conducted with the participation of cosmonauts and astronauts on the orbital stations Salyut, Mir and the International Space Station, as well as under the simulated microgravity conditions on Earth, show that the changes caused by microgravity can be partially or completely prevented by means of countermeasures [ 240 , 241 , 243 , 244 ].…”

“…Within the framework of this experiment, two protocols of countermeasures were compared—intensive interval exercise combining aerobic and anaerobic loading zones, and prolonged low intensive aerobic exercise. Interval exercise in space flight led to the preservation of muscle function almost at the pre-flight level [ 243 ]. In 2020, the effectiveness of high-intensity exercise on orbit was confirmed in an experiment by NASA [ 244 ].…”

Skeletal muscle is capable of changing its structural parameters, metabolic rate and functional characteristics within a wide range when adapting to various loading regimens and states of the organism. Prolonged muscle inactivation leads to serious negative consequences that affect the quality of life and work capacity of people. This review examines various conditions that lead to decreased levels of muscle loading and activity and describes the key molecular mechanisms of muscle responses to these conditions. It also details the theoretical foundations of various methods preventing adverse muscle changes caused by decreased motor activity and describes these methods. A number of recent studies presented in this review make it possible to determine the molecular basis of the countermeasure methods used in rehabilitation and space medicine for many years, as well as to identify promising new approaches to rehabilitation and to form a holistic understanding of the mechanisms of gravity force control over the muscular system.
