The combined results suggest that the chosen exercise protocol was not able to cause cardiolocomotor synchronization, and appears to be an effect of the simultaneous action of sympathetic system over both cardiac and muscular rhythms.

Synchrogram and iCP tools currently employed for measuring CLC are not appropriate because they indicate the occurrence of this phenomenon even among subjects who ran on different days and times of each other.
The Entrainment Frequency of Cardiolocomotor Synchronization in Long-Distance Race Emerges Spontaneously at the Step Frequency
- 2020
Medicine
Spontaneous CLS occurred at faster speeds predominantly, and the entrainment frequencies matched the locomotor task, which is compatible with the concept that interventions that determine optima conditions of CLS may potentiate the benefits of the cardiac and muscle systems synchronized in distance runners.
Temporal cross-correlation between Polar ® heart rate monitor interface board and ECG to measure RR interval at rest

Medicine
The Polar HRMI Board is acceptable for assessment of serial RR intervals and the results support the reliability of the Mean RR interval compared to a resting ECG.

Determining the probability of CLS by chance as a function of its duration found that, during running, CLS likely results from entrainment, whereas, during cycling, it results from chance, occurring when the cardiac rhythm approached the locomotor rhythm.
Time-frequency analysis of heart rate variability reveals cardiolocomotor coupling during dynamic cycling exercise in humans.

Medicine, Engineering
It is indicated that cycling continuously modulates the cardiac chronotropic response to exercise, inducing a new component in HRV, and that workload increase during intense exercise further accentuates this cardiolocomotor coupling.

All HRV, particularly HFP, is predominantly under vagal control, and within subjects, lnLFP, lNHFP, and lnTP increased linearly with the gradually decreasing vagal blockade in all postures.

During running with a high degree of co‐ordination, oxygen uptake for a given work load was slightly but significantly lower than during running with weak co-ordination and could be increased significantly by paced breathing.

A computer-controlled, dynamic, thigh cuff occlusion device is developed that enables bilateral thigh cuffs to repeatedly inflate and deflate, one side after the other, to simulate rhythmic IMP changes during bipedal locomotion to test the hypothesis that the heartbeat is coupled with intramuscular pressure (IMP) changes so as to time the delivery of blood through peripheral tissues when the IMP is lower.

Investigation of the relationship between steady state locomotor-respiratory coordination dynamics and oxygen consumption and the results conclude that it is the increased variability of frequency coupling that results in lower oxygen consumption.

The findings suggest that running training does not change the strength of locomotor–respiratory coupling but rather how these systems adapt to changing speeds.

Medicine
The results suggest the existence of a mechanism that provides beat-by-beat regulation of RRI even when it is very short, i.e., a cardio-locomotor synchronization develops during running, when the frequencies of the two rhythms approach one another.
