The purpose oi this study is to identify clearly the physiologic significance of autonomic nervous system. This study is to find the loose of endogenous neurotransmitter while using the neural response of the neural excitatory action which is distributed to the perivascular smooth muscle through the electrical stimulation of the smooth muscle of coronary artery of pig. The effects of perivascular nerve stimulation were investigated on isolated coronary artery of pig.1 . The magnitude of contractile response to perivascular nerve stimulation increased with increasing frequency (2-80 Hz) of stimulation. 2. The contractions to perivascular nerve stimulation(40V, 40Hz. 0.5msec, 1 min) were increased greatly by pretreatment of the cholinestrase inhibitor physostigmine. 3. The contraction to perivascular nerve stimulation(40V,40Hz, 0.5msec, 1min) was antagonised markedly by the muscarinic antagonist atropine. 4. The contraction to perivascular nerve stimulation(40V, 40Hz, 0.5msec, 1 min) was blocked by the neural blocker tetrodotoxin. 5. The contractions to perivascular nerve stimulation(40V. 40Hz, 0.5msec, 1 min) were not affected significantly by the -adrenergic antagonist phentolamine or - adrenergic antagonist propranolol. 6. The contractile response by the acetylcholine was increased by the pretreatment of cholinestrase inhibitor physostigmine. The finding suggest that it is powerful excitatory action linked to muscarinic receptor by cholinergic nerve in coronary artery of pig.

The Effects of Core Strengthening Training on Baseball Throwing

The purpose of this study was to investigate the effects of core strengthening training on baseball throwing. A total of 14 subjects were recruited from among middle school baseball players. The main outcome measures were as follows: speed guns were used to measure the velocity of baseballs thrown; scored targets were used to measure throwing accuracy; and 50m measuring tapes were used to measure throwing distances. It was found that core strengthening training improved the velocity of baseballs thrown and throwing accuracy and distance. Thus, core strengthening training is effective for improving the throwing ability of baseball players.
