“…The PPG potential for the evaluation of vascular disease has been recognized for decades [18] and it is currently used in venous hemodynamic studies, allowing venous refill evaluation and venous reflux quantification parameters [1,16,[22][23] . In turn, LDF has gained relevance as a sophisticated instrument to assess the blood flow in small tissue volumes, particularly in skin areas of low capillary density [24][25][26][27][28][29][30][31] . In any case, however, none of these systems provide numbers expressed in absolute values, which means that a direct correspondence with the physiological variables cannot be drawn.…”

The muscle pump activity is an important component of venous return. Muscle weakness in the lower limb can decrease the efficacy of the calf muscle pump and compromise adequate venous return. The aim of this study was to propose an experimental model to evaluate the impact of the calf muscular pump influence on peripheral microcirculation. We studied the local microvascular response to isometric calf contraction in the standing position. Six healthy subjects (31± 9 years old) participated in this study after giving informed consent. After standing for 5 minutes, subjects performed 1 minute of maintained isometric plantar flexion with both feet before resuming the original position for another 5 minutes. Local (foot) perfusion was evaluated with photoplethysmography (PPG) and laser Doppler flowmetry (LDF), pulse rate (PR) obtained from the PPG, and calf muscle activity was followed by electromyography (EMG). Nonparametric statistics were used for phase comparisons. During calf pump activity we observed significant differences of wave PPG and LDF amplitude with a rapid replacement after calf muscle contraction stopped. Pulse rate did not change during the three protocol phases. Thus, this proposed model appears suitable to further explore the role of the muscular pump activity on the peripheral microcirculation.

Introduction: In today's rapid development of science and technology, digital network data mining technology is developing as fast as the expansion of the frontiers of science and technology allows, with a very broad application level, covering most of the civilized environment. However, there is still much to explore in the application of sports training. Objective: Analyze the feasibility of data mining based on the digital network of sports training, maximizing athletes’ training. Methods: This paper uses the experimental analysis of human FFT, combined with BP artificial intelligence network and deep data mining technology, to design a new sports training environment. The controlled test of this model was designed to compare advanced athletic training modalities with traditional modalities, comparing the athletes’ explosive power, endurance, and fitness. Results: After 30 days of physical training, the athletic strength of athletes with advanced fitness increased by 15.33%, endurance increased by 15.85%, and fitness increased by 14.23%. Conclusion: The algorithm designed in this paper positively impacts maximizing athletes’ training. It may have a favorable impact on training outcomes, as well as increase the athlete's interest in the sport. Level of evidence II; Therapeutic studies - investigating treatment outcomes.

“…The chronic symptoms of the diseases may decrease the patient activity and precipitate them. The calf muscle may assist the heart’s pumping ability in a sitting or standing posture by pushing deoxygenated blood in the lower limbs up to the heart and by facilitating diastolic filling of the capillaries [ 6 , 7 , 8 ]. Accordingly, sarcopenia and dynapenia of the calf muscle may increase the heart’s workload and worsen the cardiovascular disease condition [ 6 ].…”

BackgroundThe lower limb muscle may play an important role in decreasing the heart’s pumping workload. Aging and inactivity cause atrophy and weakness of the muscle, leading to a loss of the heart-assisting role. An electrical lower limb muscle stimulator can prevent atrophy and weakness more effectively than conventional resistance training; however, it has been reported to increase the heart’s pumping workload in some situations. Therefore, more effective tools should be developed.MethodsWe newly developed a cardiac cycle-synchronized electrical lower limb muscle stimulator by combining a commercially available electrocardiogram monitor and belt electrode skeletal muscle electrical stimulator, making it possible to achieve strong and wide but not painful muscle contractions. Then, we tested the stimulator in 11 healthy volunteers to determine whether the special equipment enabled lower limb muscle training without harming the hemodynamics using plethysmography and a percutaneous cardiac output analyzer.ResultsIn 9 of 11 subjects, the stimulator generated diastolic augmentation waves on the dicrotic notches and end-diastolic pressure reduction waves on the plethysmogram waveforms of the brachial artery, showing analogous waveforms in the intra-aortic balloon pumping heart-assisting therapy. The heart rate, stroke volume, and cardiac output significantly increased during the stimulation. There was no change in the systolic or diastolic blood pressure during the stimulation.ConclusionCardiac cycle-synchronized electrical muscle stimulation for the lower limbs may enable muscle training without harmfully influencing the hemodynamics and with a potential to reduce the heart’s pumping workload, suggesting a promising tool for effectively treating both locomotor and cardiovascular disorders.
