The Effect of Steroid Dose Regimen on the Relationship Between Lower Extremity Muscle Function and Cardiac Function in Post Heart Transplant Patients

Description: Differences in cardiovascular/aerobic function in heart transplant patients might be attributed to the rate of corticosteroid withdrawal and/or to skeletal muscle function. This hypothesis was tested among nine male, cardiac transplant recipients. Prednisone dosage was monitored, and isokinetic strength testing was performed at 4 different time periods throughout the first year post-transplantation. Cardiovascular/aerobic measurements were obtained at the fourth time period. Pre-surgery charact… more

Perceived Submaximal Leg Extension Forces of Young Adult Males

Description: The purpose was to examine actual force (AF) productions of males for accuracy during leg extensions when given a random desired force (DF) ranging from 10-90% of maximal force (MF). Thirty males ranging from 18 to 30 years of age (M = 21.99 + 3.04), who had no previous experience with the test equipment, went through 9 randomly ordered submaximal efforts followed by a maximal effort. Correlations between AF and DF were high (r > .79) and test-retest was consistent between AF (r = .87) and MF (… more

The Construct Validity of Self-Reported Historical Physical Activity

Description: The purpose of this study was to determine the construct validity of self-reported historical walking, running, and jogging (WRJ) activity. The criterion measure was concurrent performance on a maximal treadmill test. Subjects completed a medical exam and treadmill test between the years 1976 and 1985, and completed a follow-up questionnaire in 1986. Questionnaire included an item that assessed WRJ for each year from 1976 through 1985. Data analysis included Spearman correlations, partial corre… more

Effect of Chronic Alcohol Abuse and Resistance Training on the Skeletal Muscle Androgen Receptor Concentration of Rats

Description: The purpose was to examine the effect of chronic alcohol abuse on the androgen receptor content (AR) in skeletal muscle, and to determine if this effect was influenced by resistance training. Thirty-four male rats (456 ± 1 g; mean ± SE) were divided into 4 groups: Sham exercise-Ethanol, Sham exercise-Normal diet, Exercise-Ethanol, and Exercise-Normal diet. Both Exercise groups underwent a 6-week "squat" resistance training protocol and both Ethanol groups received an alcohol-rich diet throughou… more

The Effects of Motivational and Instructional Self Talk on the Attentional Focus of High School Distance Runners.

Description: The purposes of this study were to examine the (a) attentional focus strategies used by high school distance runners, (b) changes in attentional focus across four laps in three 1.6 km runs, and (c) effects of a pre-performance intervention using motivational and instructional self talk on the attentional focus strategies used by and performance of high school distance runners. Participants (N = 42) completed a background and demographic questionnaire, the Cross Country Attentional Focus Invento… more

Accuracy of Self-Reported Height, Weight, and Calculated BMI and Resulting FITNESSGRAM® Healthy Fitness Zone Classification

Description: The determination of adiposity in adolescents is often assessed with calculations of body mass indices (BMI). Researchers often obtain these measurements from self-reported (SR) values. The purpose of this study was to determine the accuracy of SR height, weight, and calculated BMI (from height and weight). SR and actual measured (ME) BMI values were compared with standards from the FITNESSGRAM® Healthy Fitness Zone (HFZ) classifications. SR height and calculated BMI were found to be accurate w… more

Treadmill validation of the Siconolfi step test.

Description: Maximal oxygen uptake (VO2max) is the internationally recognized measure of a person's cardiorespiratory fitness. Currently the most accurate way of assessing one's true VO2max involves the use of maximal exercise tests, which require the use of specialized equipment, and are time consuming and costly. The purpose of this study was to determine the validity of the submaximal Siconolfi step test to estimate VO2max. A second purpose was to determine if body fat percentage improved the validity. T… more
