Dr. James W. Navalta and Dr. T. Scott Lyons (the author), both Associate Professors of Exercise Science at Western Kentucky University, are the founders of the International Journal of Exercise Science (IJES).

IJES is a student-focused journal, in that the editors are specifically seeking research that is led by graduate or undergraduate students. Manuscripts submitted by professionals (defined as those holding a terminal degree) are also gladly accepted, provided at least one student was involved in the project and is listed as a co-author. The review process includes both student and professional researchers.

This document is a summary case study on the origination, development, marketing and on-going management of this unique research journal.

Other Evaluation of Metabolic Stress between Jumping at Different Cadences on the Digi-Jump Machine http://works.bepress.com/scott_lyons/3 http://works.bepress.com/scott_lyons/3 Wed, 24 Aug 2011 14:22:16 PDT The American College of Sports Medicine (ACSM) recommends that healthy adults achieve a minimum of thirty minutes of moderate intensity aerobic exercise five days per week. While cycling, walking, and jogging are commonly observed methods of achieving these recommendations, another option may be repetitive jumping. The purpose of this study was to examine the metabolic responses between repetitive jumping at a cadence of 120 jumps per minute (JPMs) vs. 100 JPMs when utilizing the Digi-Jump machine. Twenty-eight subjects completed two jumping trials, one at 120 JPMs and one at 100 JPMs. Subjects jumped until volitional exhaustion, or for a maximum of fifteen minutes. Oxygen uptake (VO2), heart rate (HR), respiratory exchange ratio (RER), and rating of perceived exertion (RPE) were assessed each minute of each exercise trial. RPE was differentiated, in that subjects reported perceived exertion of their total body, their upper-leg, and their lower leg. Results of this study indicated that there was no significant difference between the two trials for VO2, HR, or total body RPE. Differences were reported between trials for peak and average RER, with the 120 JPM trial eliciting a lower RER for both (peak: 1.08 + .087 vs. 1.17 + .1 p=.000; average: .99 + .076 vs. 1.04 + .098 p=.002), peak upper leg RPE (120: 15.29 + 3.89 vs. 100: 16.75 + 2.52 p=.022), and average lower leg RPE (120: 15.04 + 2.55 vs. 100: 13.94 + 2.02 p=.019). Also, there was a significant difference in exercise duration between the trials, with subjects able to exercise longer during the 120 JPM trial (12.4 + 3.42 mins vs. 9.68 + 4.31 mins p=.000). These data indicate that while the physiological stress may not be different between the two trials as indicated by VO2 and HR, the 120 JPM trial appears less strenuous as evidenced by RER values and by subjects’ ability to exercise longer at that cadence.

Cardiovascular Physiology Metabolism and Nutrition Test-Retest Reliability of the Digijump Machine http://works.bepress.com/scott_lyons/2 http://works.bepress.com/scott_lyons/2 Wed, 24 Aug 2011 14:22:14 PDT Repetitive jumping has been identified as a possible exercise modality able to provide sufficient stimulus to improve bone health. However, it is necessary to establish whether repetitive jumping can elicit a consistent physiological response with the ablity to monitor work rate. The purpose of this investigation was to determine the stability reliability of the Digijump device for the commonly used laboratory measures of oxygen uptake (VO2), heart rate (HR), and rate of perceived exertion (RPE). College-aged individuals (N = 17) completed two 3-min repetitive jumping bouts on the Digijump machine (120 jumps per minute, jump height = 1.27 cm) at least seven days apart. Stability reliability was calculated using the intraclass correlation coefficient derived from 1-way ANOVA. Absolute VO2 displayed the highest test-retest reliability (0.95), while the coefficient for relative VO2 was also acceptable (0.71). The test-retest reliability coefficients for HR (0.89), and RPE (0.75) were determined to be within acceptable limits. Coefficients for all variables compared well with the stability reliability reported for other ergometers such as the Stairmaster, treadmill, and cycle. This data represent an important step in determining the validity of the Digijump machine for physiological testing.
