Studies were made on forestomach contraction frequencies as affected by diet (brome hay, alfalfa hay, alfalfa silage and barley concentrate diet), acute cold stress and acute psychological stress. Four 15-mo-old steers fitted with ruminal fistulae were used in a 4 × 4 Latin square design. Diets did not influence contractile frequencies of the forestomachs, and did not interact with the effects of the stresses. Acute cold stress and psychological stress both produced significant increases of forestomach contraction frequencies and of heart rate. Key words: Cold stress, psychological stress, forestomach contractions, heart rate

Acute Psychological Stress

Abstract Psychological stress may have harmful physiological effects and result in deteriorating health. Acute psychological stress acts also on cardiac autonomic regulation and may lead to nonstationarities in the interbeat interval series. We address the requirement of stationary RR interval series to calculate frequency domain parameters of heart rate variability (HRV) and use binary symbolic dynamics derived from RR interval differences to overcome this obstacle. 24 healthy subjects (12 female, 20–35 years) completed the following procedure: waiting period, Trier Social Stress Test to induce acute psychological stress, recovery period. An electrocardiogram was recorded throughout the procedure and HRV parameters were calculated for nine 5-min periods. Nonstationarities in RR interval series were present in all periods. During acute stress the average RR interval and SDNN decreased compared to rest before and after the stress test. Neither low frequency oscillations (LF), high frequency oscillations (HF) nor LF/HF could unambiguously reflect changes during acute stress in comparison to rest. Pattern categories derived from binary symbolic dynamics clearly identified acute stress and accompanying alterations of cardiac autonomic regulation. Methods based on RR interval differences like binary symbolic dynamics should be preferred to overcome issues related to nonstationarities.
