Hemodynamic effects of aerobic vs resistance exercise.

PubMed · 1996-11-01 · 28 citations

Previous studies suggest that aerobic exercise lowers blood pressure (BP), while isometric exercise increases BP, at least transiently. The purpose of this study was to examine the hemodynamic effect of a 6-week training period of aerobic exercise or weight training. Twenty deconditioned healthy males ages 18-36, self-selected a training regimen. The aerobic group exercised 30 min/day, 4 times each week to achieve 60-80% maximal heart rate. The resistance group lifted weights at 65-80% maximal voluntary contraction; 3-4 sets of 8-12 repetitions; 3 day/week using large muscle groups. Hemodynamic measurements of heart rate, BP, venous capacitance, forearm blood flow, and vascular resistance were made at baseline and week 6 by plethysmography and analyzed by 2-way ANOVA. The groups showed no differences in baseline characteristics. A training effect was confirmed by a decrease in resting heart rate in the aerobic group (71.5 +/- 4.4 to 64.5 +/- 3.7, beats per minute, P = 0.004), and an increase in total work capacity in the weight lifting group (6231 vs 7508, P = 0.01). Forearm blood flow increased similarly in both groups, averaging 17% (3.5 +/- 0.2 vs 4.2 +/- 0.2 ml 100 g/min, P = 0.03), while forearm vascular resistance fell 19% (28.8 +/- 1.7 vs 24.3 +/- 1.7 mm Hg/ml/min 100 g, P = 0.08). The main differences between the groups after training was found in their response to isometric stress (1/3 maximal handgrip). The weight-lifting group had a greater increase of forearm blood flow and venous capacitance, less increase in systolic BP (SBP) and a greater fall of forearm vascular resistance, (P < 0.05) while the aerobic group had less increase in SBP and heart rate (P < 0.04) but no significant change of forearm hemodynamics. We conclude that both aerobic and repetitive weight programs have short term favorable effects on resting forearm BP and resistance. The exercise programs differ in altering the individual's physiologic response to subsequent isometric stress. However, exercise training of longer duration or greater intensity or frequency could alter these results.

A Neuroendocrine Study of Stereotactic Sub-Caudate Tractotomy

The British Journal of Psychiatry · 1984-04-01 · 8 citations

The growth hormone and hypotensive responses to clonidine have been measured in six drug free severely depressed patients before, and at two weeks after, the surgical procedure of stereotactic sub-caudate tractotomy. The responses were unaltered two weeks after operation, by which time a small clinical improvement was evident. These findings are discussed in relation to central alpha adrenoceptor functions in depression, and the effect upon this of antidepressant treatment.

Thompson Smoking and Tobacco Knowledge Test

Research Quarterly American Association for Health Physical Education and Recreation · 1964-03-01 · 1 citations

Abstract A smoking and tobacco knowledge test was constructed from valid and scientifically established concepts. Twenty-five multiple choice test items were refined to the point where the item difficulty approached ideal standards for test construction. Reading level of the test was established as appropriate for those who read at or above the seventh-grade level. The test can be used as a pre- and post-test to improve tobacco and smoking health teaching.

Changes in Body Fat, Estimated from Skinfold Measurements of Varsity College Football Players during a Season

Research Quarterly American Association for Health Physical Education and Recreation · 1959-03-01 · 19 citations

Abstract A practical way to study changes in body composition, especially body fat, by the use of skinfolds has been demonstrated. Skinfold measurements, abdomen, chest, arm, were made on varsity football players at the beginning and end of a season. Using this information, changes in body composition that occurred during conditioning and training were studied. Body weight did not change significantly, but significant losses occurred from the three skinfold sites. Body density as estimated from skinfold data increased with training and conditioning. Presumably this increase was due to loss of body fat and increase in muscle mass and other bodily components.

The Selection, Development, and Evaluation of Tobacco Smoking Concepts

Research Quarterly American Association for Health Physical Education and Recreation · 1959-05-01 · 1 citations

Abstract The purposes of this study were to determine the validity and accuracy of tobacco smoking concepts and their value to general education. Concepts were divided into physiological, psychological, and socio-economic categories. Separate juries of experts in each area rated the concepts as “true,” “false,” “debatable,” or “ambiguous.” From the jury ratings, approved lists of concepts were established. Another evaluation by a general education jury established the value of these concepts to general education. A list of comprehensive teachable concepts is available to health educators, science teachers, and others interested in tobacco smoking education.

Football Starting Signals and Movement Times of High School and College Football Players

Research Quarterly American Association for Health Physical Education and Recreation · 1958-05-01 · 5 citations

Abstract An apparatus was designed and constructed to measure movement times of football players. High school and college varsity football players were tested, using certain selected football starting signals. Rhythmic digit, rhythmic word-digit, non-rhythmic word-digit, and non-rhythmic color starting signals were used, and movement times for each starting signal were computed.
