The purpose of this study was to determine the effects of a six month aerobic exercise training regimen on cardiovascular responsivity to mental arithmetic in healthy middle-aged men and women. Subjects were randomly assigned to a moderate intensity exercise intervention or to an assessment-only control group. Before and after the intervention subjects' heart rates and blood pressures were measured doing a mental arithmetic task (N = 83). Other physiological and psychosocial measures included the Type A structured interview and a maximal exercise treadmill test. Validated adherence to the exercise regimen exceeded 75% and there were significant increases in aerobic capacity in those subjects receiving exercise training. Exercise did not significantly reduce cardiovascular responsivity to the stress task. Type A behavior did not interact with reactivity across exercisers or controls nor was it significantly correlated with adherence. The results are discussed with respect to factors that have been previously reported to potentially influence the exercise/reactivity relationship.
Plasmatic lipoproteins were evaluated in a group of 11 professional football-players after a 3-week rest, and one month later, after an intensive training (characterized by a succession of aerobic and anaerobic efforts), for engaging a new competition. At day 0, total cholesterol (TC = 4.4 +/- .04 mmol/l), triglycerides (TG = .6 +/- .04 mmol/l), and LDL-TC (2.54 +/- .18 mmol/l) were significantly decreased versus sex and age matched sedentary subjects (TC = 5.13 +/- .2 mmol/l, P less than .02; TG = .99 +/- . mmol/l, P less than .01; LDL-CT = 3.26 +/- .2 mmol/l, P less than .02). HDL-TC was increased (1.50 +/- .06 vs 1.30 +/- .05 mmol/l, P less than .05). The apoprotein A1 (apoA1) was higher in football-players (1.5 +/- .06 vs 1.16 g/l, P less than .001), while the apoprotein B (apoB) was lower (.6 +/- .03 vs .88 +/- .04 g/l, P less than .001). Even after 3 weeks of rest, the football-players lipoproteins were still identical to aerobic elite-athletes. At day +30, after a daily training involving 2 anaerobic sequences, the maximal aerobic capacity was increased by 21%, without any change in nutritional, plasmatic and hepatic status. Weight was diminished (-0.8 kg, P less than 0.05). TC (4.14 +/- .2 mmol/l), TG less than .64 +/- .08 mmol/l), LDL-TC (3.37 +/- .17 mmol/l), apo B (.64 +/- .05 g/l) were unchanged. HDL-CT fell to controls values while apoA1 increased (1.66 +/- .06 mmol/l, P less than .001). Thus, HDL-CT/apoA1 ratio (indicating the TC content of HDL) was decreased, whereas apoB/apoA1 ratio was unchanged. The decrease of TC content of HDL was not related to dietary change nor to weight decrease. As TG were stable, the lipoprotein lipase activity could not be modified.(ABSTRACT TRUNCATED AT 250 WORDS)
Investigations of some dairy enterprises of Moscow and Moscow Province have shown that the requirements of the sanitary legislation on hygienic training of workers of these enterprises are partially fulfilled, the efficiency of training is not checked up. It is necessary to improve a training programme and the latter should be implemented only by specialists. Drawbacks in the hygienic training of dairy workers should be eliminated to provide the proper quality of dairy products.
Caregivers of the residents in nursing homes are exposed to a high degree of physical and mental stress. The purpose of this study was to develop and to test the effects of skill training aimed at reducing occupational stress. The training consisting of 12 sessions of 90 minutes each was designed for nursing assistants and for care supervisors, respectively. Contents of the program are communicating with the demented, coping with job stress and cooperating with colleagues and subordinates, respectively. Eleven homes for the elderly and nursing homes were involved in the pilot study; 88 caregivers participated in the training, 34 of them were supervisors and 54 nursing assistants. The participants mainly appreciated the contents of the training. A controlled study design was applied to evaluate the training effects. 56 participants assessed their competencies, their job conditions and their health status at the beginning, at the end of the training as well as 12 weeks after the intervention had been finished. 56 persons completed the questionnaire receiving no training. Among the training participants, particularly the self-care skills improved. In addition, occupational stress could be reduced and the climate with the residents improved significantly, whereas the frequency of health problems did not change. Compared to the changes also observed in the control group, statistically significant effects were confined to the improvement of the climate with the residents. Care supervisors in general reported a higher benefit from the training than did nursing assistants. The results of the pilot study were used to adapt the training to the caregivers' needs.
When staff members of a community mental health center's day treatment program for adults with emotional problems found there was not enough time for planning and meeting program goals, they considered using volunteers to help in the treatment process. The center staff worked with the local mental health association to plan the training and use of volunteers. Twenty-five volunteers were initially selected and trained. They evaluated the training through questionnaires immediately after training and after three and six months of service. Respondents felt the training prepared them to perform their duties and understand their roles as volunteers. Volunteers have worked in the program for two and a half years; currently 28 volunteers each work approximately three hours a week.
OBJECTIVES: To provide baseline data on resident continuity of care experience, to describe the effect of ambulatory centre surgery on continuity of care, to analyse continuity of care by level of resident training and to assess a resident-run preadmission clinic's effect on continuity of care. DESIGN: Data were prospectively collected for 4 weeks. All patients who underwent a general surgical procedure were included if a resident was present at operation. SETTING: The Division of General Surgery, Queen's University, Kingston, Ont. OUTCOME MEASURES: Preoperative, operative and inhospital postoperative involvement of each resident with each case was recorded. RESULTS: Residents assessed preoperatively (before entering the operating room) 52% of patients overall, 20% of patients at the ambulatory centre and 83% of patients who required emergency surgery. Of patients assessed by the chief resident, 94% were assessed preoperatively compared with 32% of patients assessed by other residents (p < 0.001). Of the admitted patients, 40% had complete resident continuity of care (preoperative, operative and postoperative). There was no statistical difference between this rate and that for emergency, chief-resident and non-chief-resident subgroups. Of the eligible patients, 58% were seen preoperatively by the resident on the preadmission clinic service compared with 54% on other services (p < 0.1). CONCLUSIONS: This study serves as a reference for the continuity of care experience in Canadian surgical programs. Residents assessed only 52% of patients preoperatively, and only 40% of patients had complete continuity of care. Factors such as ambulatory surgery and junior level of training negatively affected continuity experience. Such factors must be taken into account in planning surgical education.
Televised endoscopy and the concept of the "assisted" endoscopic operation is of great help in teaching surgical endoscopic techniques. The use of training dummies provides a new method of training manual dexterity and surgical skills in special courses or in surgical skill laboratories. We have developed a training system for transanal endoscopic microsurgery. Operations with our technique were performed on 116 patients. Like other microsurgical techniques, our method requires a special introduction and intensive training. This paper presents our multistage, video-supported training course for teaching transanal endoscopic microsurgery. The one-day training session is divided into four steps: (1) becoming acquainted with the technology; (2) training on cloth phantom; (3) training on opened bowel; (4) training on closed bovine bowel distended by gas insufflation. Each step is introduced by a short videotape didactically demonstrating the particular aspects of the method.
Previous research and anecdotal reports have suggested that when certain teaching approaches are used, students not only learn more but also experience greater satisfaction with the training process. This study examined the effects of integrative-learning-based (IL) training in relation to lecture-based training. Employees enrolled in a 3-day manufacturing resource planning training course were randomly assigned to either IL or traditional training. Subjects reacted more favorably to IL-based training. Trained subjects performed significantly better than those in a no-treatment control group, but no differences were noted between training interventions.
OBJECTIVES: To describe how the Michigan Center for Public Health Preparedness (MI-CPHP) responded to the challenge and urgency in delivering competency-based preparedness training and documenting its impact utilizing a responsive evaluation approach. METHODS: Pretest-posttest evaluation designs were implemented when feasible to document the impact of training activities on knowledge and competency gains. The development of evaluation instruments is described with a focus on being responsive to the specific goals of each training activity. A randomized experimental design was used to examine the effects of taking a pretest for one of the training events. RESULTS: The analyses noted statistically significant improvements for every comprehensive training event in key content knowledge and self-rated competencies. The impact of taking a pretest revealed a modest, but statistically significant, effect on the self-rated competencies and a nonsignificant effect on the content knowledge scores. CONCLUSIONS: A summary of the results and their implications is followed by a discussion about taking a responsive approach to evaluating the training activities of the MI-CPHP. The challenge of evaluating the impact of knowledge-focused training activities on the development of performance competencies was also reviewed.
