This study compared the weekly training load (TL) variation across different measures. Fifty-two runners reported their heart rate and distance ran for each training session during four weeks of training. Heart rate measures were used to calculate the weekly TRaining IMPulse (W-TRIMP), whereas the distance ran was used to calculate the weekly…

Purpose: The aim of this study was to examine the physiological demands of trampolining, in comparison with treadmill running, using a larger sample size and a wider range of physiological measures, than had been reported in the previous research. Method: Twenty-three healthy adults completed three, three-minute exercise bouts on both a trampoline…

This study was aimed at investigating the impact of music on exercise performance and affective response to exercise in individuals with Down syndrome (DS). Twelve individuals with DS completed a treadmill walking protocol in both music and no music conditions. Heart rate (HR), walking steps, rate of perceived exertion (RPE), and enjoyment scores…

This study revises and enhances a guided inquiry activity designed to introduce undergraduate and high school students to the physiological concepts of exercise fatigue during a 400-meter dash. This activity has been employed since 2016 in entry-level human physiology courses at the University of Minnesota and across 30 high schools. Using…

Purpose: To compare the effects of a single bout of eccentric cycling (ECC) and eccentric cycling with blood flow restriction (ECC[subscript BFR]) on the changes in cardio-metabolic demand and indirect markers of muscle damage in healthy men. Method: Twenty-one young men (24.0 ± 3.2 y) were randomly allocated in two groups to perform a 30-min…

Objectives: The purpose of the current study was to examine the effects of using an activity workstation on the physiological stress response as measured by heart rate variability while completing cognitively demanding tasks. Participants: Eleven college students (6 females; age: 19.4 ± 0.9 years) participated in the study. Methods: The…

Purpose: The association between an overlooked classical Lactate Threshold (LT), named "Minimum Lactate Equivalent" (LE[subscript min]), with Maximal Lactate Steady State (MLSS) has been recently described with good MLSS prediction results in endurance-trained runners. This study aimed to determine the applicability of LE[subscript min]…

This dissertation is presented in multiple article format with an introduction, a literature review, a design case, a mixed methods study, and a conclusion. The literature review outlines important concepts and theories that appear in subsequent manuscripts. The design case describes the seven-year design process that resulted in the online…

The YMCA step test uses a prescribed step height which is difficult in a telehealth setting. Examine a modification of the YMCA step test allowing for the use of preexisting in-home objects of variable height as the "step" in a virtual environment. Young healthy participants (n = 40) performed step tests with a small and large object of…

Objectives: To explore the preliminary effects and acceptability of a co-produced physical activity referral intervention. Study Design: Longitudinal design with data collected at baseline and post a 12-week physical activity referral intervention. Setting: Community leisure centre. Methods: In all, 32 adults with controlled lifestyle-related…

This study compared the energy expenditure (EE) levels during object projection skill performance (OPSP) as assessed by indirect calorimetry and accelerometry. Thirty-four adults (female n = 18) aged 18-30 (23.5 ± 2.5 years) performed three, 9-min sessions of kicking, over-arm throwing, and striking performed at 6-, 12-, and 30-sec intervals. EE…

Electronic pedometers are relatively inexpensive devices to monitor physical activity. To assess physical activity intensity using a pedometer, establishing the relationship between step-rate measured by a pedometer and the rate of oxygen uptake (VO[subscript 2]) is needed. This study examined the step-counting accuracy of the NL-2000i electronic…

At some point in the future, if mankind hopes to settle planets outside our solar system, it will be crucial to determine the range of planetary conditions under which human beings could survive and function. In this article, we apply physical considerations to determine the limitations that gravity imposes on several systems governing the human…

Purpose: The purpose of this study was to evaluate the agreement of five commercially available accelerometers in estimating energy expenditure while performing an acute bout of high-intensity functional training (HIFT). Methods: Participants (n = 47; average age: 28.5 ± 11.6 years) consisted of recreationally active, healthy adults. Each…

The activPAL is a widely-used measure of sedentary time but few studies have evaluated its ability to estimate physical activity intensity. This study determined the accuracy of the algorithm used by the activPAL to predict metabolic equivalents (METs) from cadence and a curvilinear cadence-METs equation individualized for height. Thirty-six…
