Persons living in individualistic cultures with low levels of differentiation of self are prone to experiencing internal distress. The specific pathway by which this relationship occurs, however, has been minimally studied. We hypothesized that two psychological constructs which are related to differentiation of self—vulnerable narcissism and malad...

Recently we reported similar performances in both progressive tests to exhaustion (VO2max) and 5km running time trials (5KTT) after consuming low-carbohydrate, high-fat (LCHF) or high-carbohydrate, low-fat (HCLF) diets. Accordingly, we tested the null hypothesis that the metabolic responses during both tests would be similar across diets. In a rand...

A growing number of endurance athletes have considered switching from a traditional high-carbohydrate/low-fat (HCLF) to a low-carbohydrate/high-fat (LCHF) eating pattern for health and performance reasons. However, few studies have examined how LCHF diets affect blood lipid profiles in highly-trained runners. In a randomized and counterbalanced, cr...

Introduction: To examine the effects of voluntary hyperventilation (VH) between sets of bench press (BP) and squat (SQ) at 70 and 90% 1RM on repetitions to failure, power, bar velocity, blood lactate, session RPE (sRPE), and muscle oxygen saturation (SmO2). Methods: Fifteen recreationally trained (2.92 ± 2.18 yrs. of resistance training experience)...

Exogenous ketone esters have demonstrated the capacity to increase oxygen availability during acute hypoxic exposure leading to the potential application of their use to mitigate performance declines at high altitudes. Voluntary hypoventilation (VH) with exercise reliably reduces oxygen availability and increases carbon dioxide retention without al...

The effects of a novel quadrupedal movement training program on functional movement, range of motion, muscular strength, and endurance. J Strength Cond Res XX(X): 000-000, 2020-Quadrupedal movement training (QMT) is a form of bodyweight training incor...

Background: Interest into the health, disease, and performance impact of exogenous ketone bodies has rapidly expanded due to their multifaceted physiological and signaling properties but limiting our understanding is the isolated analyses of individual types and dose/dosing protocols. Methods: Thirteen recreational male distance runners (24.8 ±...

Low-Carbohydrate High-Fat (LCHF) diets have become very popular among athletes due to recent research suggesting performance and numerous health benefits. However, few studies have examined the chronic effects of LCHF diets on the blood lipid profile and other cardiovascular disease risk factors in athletic populations. PURPOSE: To examine the effe...

Ground-based movement training (GMBT) is a unique form of bodyweight training that incorporates various animal poses, transitions, and crawling patterns to reportedly improve fitness and performance. GBMT is growing in popularity and being used in numerous settings including general fitness, strength and conditioning for sport, and physical rehabil...

A quasi-experimental design was employed to (a) assess the long-term impact of study abroad, service-learning, community service, and cultural coursework as alternative methods of expanding long-term global awareness among college students, and (b) evaluate the predictive validity of a standard secular assessment tool at a rural Christian college....

A common belief is that high intensity exercise (>60%VO2max) is best sustained by high rates of carbohydrate oxidation. The belief is based, in part, on an idea developed by Krogh and Lindhard in 1920. In the 100 years since, few studies have tested its validity. We tested the null hypothesis that performance in competitive recreational athletes ex...

Introduction: The purpose of this study was to evaluate the independent and combined effects of energy drink (ED) functional ingredients, caffeine (CAF), taurine (TAU), and glucose (GLU) on 5-km running time trial (5KTT) performance in recreational endurance runners. Methods: Twenty recreational endurance runners (10 men, 10 women, 21.3 ± 2.2 years...
Article
The purpose of this study was to evaluate exercise performance time as well as related physiological and perceptual responses of recreational endurance runners after they had ingested a commercially available energy drink (Red Bull®) containing caffeine, glucose, and taurine. Recreational endurance runners (n = 18, 13 men, 5 women, 20.39 ± 3.27 yea...

... In total, 20 studies were selected in this study, including 15 RCTs [8,[31][32][33][34][35][36][37][38][39][40][41][42][43][44] and 5 non-RCTs [45][46][47][48][49]. All were published between 2016 and 2022 as peer-reviewed articles or dissertations. ...
... Participants were instructed to refrain from caffeine and alcohol consumption for 48 h and racing or training for 24 h, and food and drink for 3 h (post-prandial minimum time window) before each experimental trail. Participants were instructed to maintain their usual training frequency and log (mode, duration, and intensity of each workout) throughout the study intervention (Prins et al., 2020). Training load for each session was calculated by using the session-RPE method (RPE × session duration [min]) (Foster et al., 2001). ...
... Recently we reported the results of a dietary randomized controlled trial in which the same subjects performed 5 km time trials following exposure to LCHF or HCLF diets [47]. As the subjects also completed progressive VO 2 max exercise tests to exhaustion when eating either the HCLF or LCHF diets, we realized that a complete data set was available to determine the effects of these two different diets on carbohydrate and fat metabolism during progressive maximal exercise to exhaustion. ...
... The smallest worthwhile change (SWC) was predetermined to be 0.65%. This is midway between the smallest worthwhile change in day-to-day variability in competitive middle distance and distance runners [34] and the estimated coefficient of variation in our laboratory [25,30,35]. Post hoc analyses of significant main and interaction effects were conducted where appropriate using the Bonferonni adjustment to determine which conditions were significantly different. ...
... The speed indicator and timing devices were concealed from the participant's view throughout the TT. Therefore, participants regulated their treadmill pace according to their perceived exertion associated with the intensity of the exercise and their subjective feelings of their running capabilities [49]. ...
