Aortic Baroreceptor Reflex Control of Blood Pressure: Effect of Fitness

Description: Aortic baroreflex (ABR) control of blood pressure was examined in 7 untrained (UT) and 8 endurance exercise trained (EET) young men. ABR control of blood pressure was determined during a steady state phenylephrine infusion to increase mean arterial pressure 10-15 mmHg, combined with positive neck pressure to counteract the increased carotid sinus transmural pressure, and low levels of lower body negative pressure to counteract the increased central venous pressure. Functioning alone, the ABR wa… more

The Effectiveness of an Exercise Intervention Program in Reducing Cardiovascular Risk Among Employees in a University Setting

Description: Nine physiological measures were evaluated pre- to post-intervention on subjects participating in a university health promotion program over a seven-month period. Frequency of program attendance and choice of activity were also assessed. Of the 88 employees initially screened, most of the subjects were staff members (n=82, 93%),with a majority being female (n=68, 77%). Significant differences in physiological measures were found pre- to post-intervention between "higher" and "lower" cardiovascu… more

Effects of Endurance Intensity and Rest Interval on Subsequent Strength Performance

Description: The purpose of this study was to examine the acute effects of cycling exercise at different intensities and rest intervals on strength performance. Ten males, engaged in concurrent training for at least one month prior to testing, comprised the subject group for this study. Results show only leg press torque and leg press work to be decreased after cardiorespiratory exercise of moderate intensity. Leg extension average power, chest press torque, chest press power, and chest press work after cyc… more

Responses During Exercise at 90% and 100% of the Running Velocity Associated with VO2max (vVO2max)

Description: Six male long-distance runners participated in this study to evaluate the responses to exercise at 90% and 100% vV02max. Subjects participated in five maximal exercise tests: one incremental, three tests at 90% vV02max, and one test at 100% vV02max. The results of this study demonstrate that V02max can be elicited in a constant-velocity test at 90% vV02max.

Development and Validity of the Teachers' Attitude, Comfort and Training Scale (TACTS) on Sexuality Education

Description: The purpose of the study was to design and validate an instrument designed to investigate teachers' attitudes in regard to adolescent sexuality education. Test development adhered to the guidelines of Aligna and Crocker. Cronbach alpha was performed on the entire instrument and determined the reliability to be .8003, thus the instrument was consistent in measuring the domain areas. A panel of experts assessed content validity of items. A principal component factor analysis and a Pearson's produ… more

The Effectiveness of a Cholesterol Reduction Intervention Program Among Female Employees in a Corporate Setting

Description: Three cholesterol interventions were evaluated in a work-site setting to determine which was most effective in modifying physiological, behavioral, and knowledge measures related to total serum cholesterol. Of the 246 employees initially screened, 135 (55%) were identified as having elevated total serum cholesterol levels (>200 mg/dl) and were eligible for the study. Treatment consisted of either a six-session cholesterol reduction course requiring 30 days dietary monitoring, a six-session cour… more

Critical Power as a Predictor of Performance in a Bicycle Time Trial

Description: Certain measures of aerobic power have been shown to have a high relationship with endurance performance. Critical power (CP) has also been shown to be well correlated to endurance performance, but few studies have evaluated its use in a competitive scenario. In this study, cardiorespiratory-metabolic measures were evaluated in 13 highly trained cyclists to determine their relationship to performance in a 17 km time trial. Critical power, determined from the nonlinear power-time model, was also… more

The Significance of Time to Exhaustion at the Velocity at VO2Max

Description: There were two primary goals in this investigation. The first goal was to determine if inter-individual variability in time to exhaustion at the velocity associated with V02max (Tlim at Vmax) was explained by anaerobic capacity (AC), Vmax, anaerobic threshold (AT), and/or a combination variable in the form [AC • (Vmax - vAT)^-1]. The second goal was to determine if AC could be predicted from Tlim at Vmax, AT, and/or a combination variable in the form [Tlim • (Vmax - vAT)].

Predicting Peak Oxygen Uptake from Ratings of Perceived Exertion During Submaximal Cycle Ergometry

Description: The purpose of this study was to predict VO2pak using ratings of perceived exertion (RPE), heart rate (HR), and percent fat (PFAT). Subjects were males (n= 60) (PFAT, M SD = 14.4 6.1) and females (n= 67) (PFAT, M SD = 23.4 4.9) with ages ranging from 18 to 33 years. Subjects performed an incremental cycle ergometer protocol and RPE, HR and Vo2 were measured at each stage until VO2 ak was achieved. Mean RPE and HR at the submaximal workload of 100 watts were, (RPE100) M= 12.7 2.6 and (HR100) M= … more

Morning and Afternoon Response to Exercise Using Two Test Protocols

Description: The purpose was to investigate time of day on responses to two types of exhaustive cycle ergometer tests. Sixteen males performed six exercise tests: three - constant power protocol and three - incremental protocol. The first test was a learning trial; the other tests were performed one in the morning and one in the afternoon. ANOVA revealed that O2 deficit and lactate were higher in the afternoon than the morning. Regardless of test type, time to exhaustion tended to be higher in the afternoon… more

Event Order in the Biathlon Does Not Have an Effect on Metabolic Response

Description: The purpose of this study was to examine the effects of event order on a cycling(C)/running(R) or R/C biathlon. Eight experienced male biathlete/triathletes with a mean age of 24.9 + 4.6 yr formed the sample of the study. Results show no significant interaction effects on oxygen consumption peak, oxygen consumption during steady-state, ventilation, and heart rate when C/R or R/C are performed at 70% oxygen consumption peak for subsequent R and C respectively. These results seem to indicate that… more
