Effect of circulatory system response to motor control in one-sided contractions

Effect of circulatory system response to motor control in one-sided contractions Purpose The purpose of this study was to clarify the effect one-sided skeletal muscle contraction has on the circulatory system, spinal α-motoneuron excitability, and somatosensory-system-evoked potential. Method Nine healthy males maintained tension at 10, 20, and 30% of maximal voluntary contraction in static gripping in right hand. Heart rate, ln high frequency (HF), blood pressure (BP), F-wave, and somatosensory-evoked potential (SEP) were recorded during gripping task. BP, F-wave and SEP were recorded from left hand (contralateral side from contracting side). Result and conclusion There were significant main effects of contractions strength on heart rate (0%: 68.2 ± 6.8 bpm, 10%: 67.6 ± 7.4  bpm, 20%: 69.7 ± 8.5  bpm, 30%: 73.7 ± 9.3  bpm, F =9.18, P < 0.01), systolic BP (0%: 127.7 ± 15  mmHg, 3.24 10%: 136.2 ± 13.5 mmHg, 20%: 136.2 ± 13.5 mmHg, 30%: 140.0 ± 17.1 mmHg, F =23.93, P < 0.01), diastolic BP (0%: 3.24 69.3 ± 8.5 mmHg, 10%: 76.9 ± 11.1 mmHg, 20%: 79.9 ± 12.5 mmHg, 30%: 86.2 ± 14 mmHg, F =17.09, P < 0.01), and 3.24 F-wave appearance rate (0%: 29.7 ± 15.6%, 10%: 39.3 ± 20.5%, 20%: 47.5 ± 22.9%, 30%: 55.2 ± 21.8%, F =14.04, P < 0.01). 3.24 For the ln HF (0%: http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png European Journal of Applied Physiology Springer Journals
