Effect of Posture on Respiratory Sinus Arrhythmia in Young Females
Effect of posture on the amplitude of respiratory sinus arrhythmia (RSA) at some breathing periods between 4 and 12 sec was studied in standing and supine female students of a physical education college.Tidal volume increased in accordance with the respiratory period. RSA amplitude, measured as heart period (i. e, pulse interval) change, was greater in supine position than in standing posture when the respiration period was rather short, that is …
Differential Fatiguability of Human Skeletal Muscles
Fatiguability for sustained isometric contraction was investigated for human limb muscles by means of frequency analysis of the bipolar surface electromyogram. The contraction strength was two-thirds or a half of themaximum strength. The increase of slow wave ratio (the proportion of the integrated amplitude in the frequency component below 60 Hz to the total activity) in the electromyogram from initial slow wave ratio was calculated to evaluate …

Differential Fatiguability between the One- and Two-Joint Muscles
The present study was designed to confirm the differential f atiguability between the one and two-joint muscles by the frequency analysis of the EMG activities of each pair of elbow flexors (M. biceps brachii and M. brachioradialis), knee extensors (M. rectus femoris, M. vastus medialis, and M. vastus lateralis), and ankle extensors (M. gastrocnemius and M. soleus). The results are summarized as follows :(1) The lowering in the frequency spectra …
