The Relationship

Participants' heart rate and skin resistance responses to emotional memories (fear, anger, joy, sadness, and embarrassment) were studied to determine if the recollection of emotion is sufficient to produce psychophysiological changes, to determine if such changes differ for the various emotions, and to determine the relationship between imaginal abilities and psychophysiological responses to emotional memories. The Absorption Scale of the Multidimensional Personality Questionnaire was used as the measure of imaginal ability [1]. A repeated measures analysis of variance indicated significant differences for skin resistance but not heart rate among emotional memories, F(5,75) = 4.22, p = .002. Recollection of emotional memories, therefore, can produce psychophysiological changes in skin resistance which resemble emotions in real-life circumstances. A theoretical framework for interpretation of results on emotional memories is presented.

Purpose:This study looked at the physiological effects of performance in Highland-dance competition to consider whether the traditional methods used during class and rehearsal provide an appropriate training stimulus toward this performance.Methods:Nine championship standard, female Highland dancers (age 14.2 ± 1.47 years) had their heart rate and blood lactate concentrations measured before and after 3 dances during a championship competition. Heart rate was also measured during the same 3 dances in rehearsal and during class.Results:Repeated-measures analysis of variance showed significant differences in pre dance lactate concentrations between the first dance (Highland Fling, 1.4 ± 0.3 mM/L), the second dance (Sword dance, 2.3 ± 0.8 mM/L), and the third dance (Sean Truibhas, 3.5 ± 1.8 mM/L; F2,16 = 11.72, P < .01. This, coupled with a significant rise in lactate concentration during the dances (F1,8 = 76.75, P < .001), resulted in a final post dance lactate concentration of 7.3 ± 2.96 mM/L. Heart-rate data during competition, rehearsal, and class (195.0 ± 6.5, 172.6 ± 5.4, and 151.9 ± 7.4 beats/min, respectively) showed significant differences between all 3 (F2,16 = 107.1, P < .001); these are comparable to research on other dance forms.Conclusions:Given the disparity between the anaerobic predominance of competition and the aerobic predominance during class, it is suggested that the class does not provide an appropriate training stimulus as preparation for competitive performance in Highland dance.

ABSTRACT Objective:  To investigate the relationship between a micropulse vibration device and pain perception during orthodontic treatment. Materials and Methods:  This study was a parallel group, randomized clinical trial. A total of 58 patients meeting eligibility criteria were assigned using block allocation to one of two groups: an experimental group using the vibration device or a control group (n  =  29 for each group). Patients used the device for 20 minutes daily. Patients rated pain intensity on a visual analog scale at appropriate intervals during the weeks after the separator or archwire appointment. Data were analyzed using repeated measures analysis of variance at α  =  .05. Results:  During the 4-month test period, significant differences between the micropulse vibration device group and the control group for overall pain (P  =  .002) and biting pain (P  =  .003) were identified. The authors observed that perceived pain was highest at the beginning of the month, following archwire adjustment. Conclusion:  The micropulse vibration device significantly lowered the pain scores for overall pain and biting pain during the 4-month study period.

Background:Little is known about the relationship between children’s physical activity (PA) in preschool (in-school) and outside of preschool (out-of-school). This study described this relationship.Methods:Participants were 341 children (4.6 ± 0.3 years) in 16 preschools. Accelerometers measured moderate-to-vigorous physical activity (MVPA) and total physical activity (TPA) in-school and out-of-school. In the full sample, Pearson correlation was used to describe associations between in-school and out-of-school PA. In addition, children were categorized as meeting or not meeting a PA guideline during school. MVPA and TPA were compared between the 2 groups and in-school and out-of-school using 2-way repeated-measures analysis of variance.Results:In the full sample, in-school and out-of-school PA were positively correlated for MVPA (r = .13, P = .02) and TPA (r = .15, P = .01). Children who met the guideline in-school remained comparably active out-of-school. However, those who did not meet the guideline were more active out-of-school than in-school. The groups were active at comparable levels while out-of-school. Identical patterns were seen for MVPA and TPA.Conclusions:Children’s in-school PA was positively associated with out-of-school PA. Children who did not meet the guideline in-school were more active out-of-school than in-school, suggesting preschool and classroom factors may reduce some children’s PA in-school.

Aim: to assess the relationship between deep overbite with palatal impingement and periodontal health status in a cohort of adult Saudi dental patients. Materials and Methods:Ten patients (4 males and 6 females, aged 16 to 31 years old) with deep traumatic overbite and palatal impingement were examined. A Hawley retainer appliance with an anterior bite plate was provided for all patients.Pocket depth, bleeding index, gingival index, plaque index and mobility were recorded for four visits after using the appliance with fixed intervals in-between. Repeated measures analysis of variance (ANOVA) was used to assess the differences between visits, control /experimental teeth and surfaces (palatal /labial) for pocket depth, bleeding index, plaque index,gingival index and mobility.

Abstract. The effects of time after birth and of twinning on rectal temperature (RT), heart rate (HR), respiratory rate (RR) and body weight (BW) values were evaluated in five singleton Comisana lambs (three males and two females), five singleton Maltese Kids (three males and two females), four couples of twin Comisana lambs (four males and four females) and four couples of twin Maltese kids (four males and four females) during the first month of life. For all kids and lambs, RT, HR, RR and BW were recorded after 1 and 24 h from birth and every 2 days until the 30th day of life. The application of two-way repeated measures analysis of variance (ANOVA) showed a statistically significant effect of time (P < 0.0001) on RT, HR, RR and BW values in all lambs and kids during the first month of life. Any significant effect of twinning (P > 0.05) on all studied parameters was found in lambs, whereas statistically significant differences in BW, RT and HR values (P < 0.01) were found between twin and singleton kids throughout the first month of life. The results obtained in this study make a contribution to the knowledge of homeostatic, cardiorespiratory and thermoregulatory adaptations occurring in singleton lambs and kids and in twin lambs and kids during the first 30 days of life. Our findings indicate that the BW, RT, HR and RR values, whose homeostasis is still evolving in newborn, should be interpreted dynamically as a function of the period of postnatal adaptation and also of twinning.

Improve Access

To describe the relationship between jaw opening and access to the deep parotid window, we identified the following distances in 10 human skulls: symphysis to angle of mandible, mastoid tip to angle of mandible, angle of mandible to condylar process, and mastoid tip to condylar process. With the jaw closed and open, these distances were measured with 1 to 3 wooden blocks, each measuring 1 cm, between the upper and lower incisors. The triangular deep parotid area formed by the last 3 distances was calculated. A repeated measures analysis of variance showed a significant decrease in the deep parotid area with increasing interincisal distance ( P < .01). A generalized estimating equation model demonstrated a statistically significant decreasing area of the deep parotid window with increasing interincisal distance. These results suggest that nasal intubation may improve access to the parotid window.

Purpose: This study explored the relationship between migrant farmworker (MFW) stress and salivary cortisol (sC) in a sample of MFWs prior to migration. Sample: The sample, 40 ( N = 14 male, 26 female) adult MFWs residing in the lower Rio Grande Valley of Texas, primarily comprised middle-aged immigrants with a middle-school education. Design: This pilot feasibility study included a self-report farmworker stress inventory and five serial sC specimens in 24 hr. Results: The sC measures reflected an expected diurnal pattern. Lower total cortisol (area under the curve with respect to ground) was significantly associated with greater waist circumference ( r = –.63, p ≤ .01). Repeated measures analysis of variance (ANOVA) indicated that participants who perceived high levels of farmworker stress exhibited a significant change in sC over time; F(2.14, 72.65) = 43.90, p < .001. High- and low-perceived-stress groups differed significantly in the trajectory of changes in sC over the five time points. Conclusion: MFWs experienced significant levels of stress during premigration. Their sC responses varied significantly by level of perceived farmworker stress. Lower perceived stress may reflect blunting of the sC response pattern.

The aim of this study was to examine the effect of acuteRhodiola rosea(R. rosea) ingestion on substrate utilisation, mood state, RPE, and exercise affect. Ten males (mean age ± S.D. = 26 ± 6 years) completed two 30-minute cycling trials at an intensity of 70% ofV˙O2max⁡following ingestion of either 3 mg·kg−1body mass ofR. roseaor placebo using a double-blind, crossover design. During exercise, heart rate and RPE were recorded. Participants completed measures of mood state and exercise affect before and after exercise. Expired air samples were taken during exercise to determine substrate utilisation. Repeated measures analysis of variance indicated that RPE was significantly lower at 30 minutes into exercise versus placebo (P=0.003). Perceptions of arousal (P=0.05) and pleasure were significantly higher after exercise withR. roseacompared to placebo (P=0.003). Mood state scores for vigor were also higher inR. roseacondition compared to placebo (P=0.008). There were no significant differences in energy expenditure, carbohydrate, or fat oxidation between conditions (P>0.05). Ingestion ofR. roseafavourably influenced RPE and exercise affect without changes in energy expenditure or substrate utilization during 30-minute submaximal cycling performance.
