International Journal of Exercise Science

International Journal of Exercise Science 12(5): 979-988, 2019. The basis of learning is knowledge of discrete information such as terms and definitions that can be developed through memorization. A strong knowledge base is something students strive to develop through self-directed study. Little research has investigated the role of simultaneous exercise and memorization on recall ability with a delay in recall of at least 24 hrs. The purpose of this study was to evaluate the effect of an exercise bout on memory by requiring participants to recall words 24 hrs after exposure to three different interventions: memorization while cycling, memorization ...


Quantitative Analysis Of The Kinematics Of The Foot During Gait With Respect To Barefoot Running Shoes Using A Multi-Segment Foot Model, Lisa Y. Oikawa 2019 The University of Western Ontario

Quantitative Analysis Of The Kinematics Of The Foot During Gait With Respect To Barefoot Running Shoes Using A Multi-Segment Foot Model, Lisa Y. Oikawa

Electronic Thesis and Dissertation Repository

Kinematics of the foot during static and dynamic tasks are technically challenging to accurately measure, making it difficult to evaluate their contribution to running-related injuries. Motion capture can detect changes in running mechanics, such as with differing footwear. Habitual barefoot runners and/habitual minimalist shoe runners underwent a biomechanical evaluation of their foot movement during running using reflective markers and optical motion capture. A five-segment foot model was used to compare motions between the different parts of the foot while running barefoot and wearing Vibram Five Fingers™ (VFF) barefoot mimicking shoes. Supination/pronation in the forefoot was larger but not ...

Implementing Eccentric Resistance Training—Part 1: A Brief Review Of Existing Methods, Timothy J. Suchomel, John P. Wagle, Jamie Douglas, Christopher Taber, Melissa Harden, G. Gregory Haff, Michael H. Stone

Christopher Taber

The purpose of this review was to provide a physiological rationale for the use of eccentric resistance training and to provide an overview of the most commonly prescribed eccentric training methods. Based on the existing literature, there is a strong physiological rationale for the incorporation of eccentric training into a training program for an individual seeking to maximize muscle size, strength, and power. Specific adaptations may include an increase in muscle cross-sectional area, force output, and fiber shortening velocities, all of which have the potential to benefit power production characteristics. Tempo eccentric training, flywheel inertial training, accentuated eccentric loading, and ...

Student-Athlete Compensation: An Alternative Compensation Model For All Athletes Competing In Ncaa Athletics, Mike Stocz, Nicholas Schlereth, Dax Crum, Alonzo Maestas, John Barnes

Faculty Publications

The Ed O’Bannon case (O’Bannon v. National Collegiate Athletic Association, 2015) has brought student-athlete compensation to the national spotlight. While the NCAA continues to defend its policy of amateurism, the time for college athlete compensation may soon become a reality (NCAA Division I Manual, 2019). Recent college athlete compensation models have explored revenue sharing models similar to that of professional sports leagues, although previous research failed to develop a compensation model for athletes in sports beyond basketball and football (Huma & Staurowsky, 2013). The current research argues for a more applied, market economy compensation model to offer fair compensation ...

Cluster set loading in the back squat: Kinetic and kinematic implications. J Strength Cond Res XX(X): 000–000, 2018—As athletes become well trained, they require greater stimuli and variation to force adaptation. One means of adding additional variation is the use of cluster loading. Cluster loading involves introducing interrepetition rest during a set, which in theory may allow athletes to train at higher absolute intensities for the same volume. The purpose of this study was to investigate the kinetic and kinematic implications of cluster loading as a resistance training programming tactic compared with traditional loading (TL). Eleven resistance-trained ...

BACKGROUND: Traditional exercise [supervised exercise (SE)] intervention has been proved to be one of the most effective ways to improve metabolic health. However, most exercise interventions were on a high-cost and small scale, moreover lacking of the long-term effect due to low engagement. On the other hand, it was noteworthy that gamification and social incentives were promising strategies to increase engagement and sustain exercise interventions effects; as well as mobile technologies such as WeChat also can provide an appropriate platform to deploy interventions on a broader, low-cost scale. Thus, we aim to develop a novel exercise intervention ('SandG exercise intervention ...
