Evoked R-states with Progressive Muscle Relaxation (PMR) and yoga stretching Psychology 1100 051 The present article summarizes Ghoncheh and Smith’s (2004) 5 week study of the evoked effects of progressive muscle relaxation (PMR) and yoga stretching on R-states. Smith’s (1999a‚ 1999b‚ 2001‚ 2002) Attentional Behavioral Cognitive (ABC) relaxation theory proposes 15 psychological relaxation-related states (R-States): Sleepiness‚ Disengagement‚ Physical Relaxation‚ Mental Quiet‚ Rested/Refreshed

enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚ forward (favored by Type II skeletal muscle) and reverse (favored by Type I skeletal muscle and the heart).

February‚ 2013 iWorx Lab Report 01 - Agonist/Antagonist Muscles In this first iWorx lab‚ students studied and observed agonist and antagonist muscles. Agonist‚ which are also known as prime movers‚ are the main muscles that are responsible for bringing two bones closer. The antagonist‚ is the muscle that relaxes as the agonist contracts. The lab was a physical example to show students which muscle was which. It also allowed students to see how the muscle activity was recorded by an electromyogram (EMG)
