Estimates Of Persistent Inward Current Decline In Human Soleus Motor Units During Fatigue, Kirby Mendes
Estimates Of Persistent Inward Current Decline In Human Soleus Motor Units During Fatigue, Kirby Mendes
Theses and Dissertations (Comprehensive)
Fatigue is defined as any exercise induced reduction in strength or power, and can be attributed to central and peripheral components. Many central and peripheral mechanisms have been extensively studied, but few studies have looked at the changes in the intrinsic properties of motor neurons and their contribution to fatigue. Persistent inward current (PIC) is an important intrinsic property of motor neurons responsible for setting a large increase in the gain of motor output and may contribute to fatigue. Inhibitory inputs such as reciprocal inhibition (RI) have been shown to turn off PICs and reducing the gain of output. PIC …
Effects Of A Heart Rate Variability Biofeedback Intervention On Athletes’ Psychological Responses Following Injury, Andrew S. Rollo Mr.
Effects Of A Heart Rate Variability Biofeedback Intervention On Athletes’ Psychological Responses Following Injury, Andrew S. Rollo Mr.
Theses and Dissertations (Comprehensive)
The purpose of this study was to evaluate the effectiveness of heart rate variability biofeedback (HRV BFB), a form of psychophysiological skills intervention, to improve athletes’ psychological response following an injury. Further, to examine the effects of HRV BFB on self-efficacy, perceived stress and anxiety, pain management, and the psychological responses of injured athletes. HRV BFB effects on athletes’ physiological indices including HRV, HR, and respiration rate were also assessed. Participants were 32 athletes who had sustained a moderate to severe musculoskeletal sports injury, ranging in age from 18 to 36 years (Mage = 20.82, SD = 3.41). …
