Timing Of Ergogenic Aids And Micronutrients On Muscle And Exercise Performance, Richard A. Stecker, Patrick S. Harty, Andrew S. Jagim, Darren G. Candow, Chad M. Kerksick

Faculty Scholarship

The timing of macronutrient ingestion in relation to exercise is a purported strategy to augment muscle accretion, muscle and athletic performance, and recovery. To date, the majority of macronutrient nutrient timing research has focused on carbohydrate and protein intake. However, emerging research suggests that the strategic ingestion of various ergogenic aids and micronutrients may also have beneficial effects. Therefore, the purpose of this narrative review is to critically evaluate and summarize the available literature examining the timing of ergogenic aids (caffeine, creatine, nitrates, sodium bicarbonate, beta-alanine) and micronutrients (iron, calcium) on muscle adaptations and exercise performance. In summary, preliminary data …

Implementing Eccentric Resistance Training—Part 2: Practical Recommendations, Timothy J. Suchomel, John P. Wagle, Jamie Douglas, Christopher Taber, Melissa Harden, G. Gregory Haff, Michael H. Stone

Exercise Science Faculty Publications

The purpose of this review is to provide strength and conditioning practitioners with recommendations on how best to implement tempo eccentric training (TEMPO), flywheel inertial training (FIT), accentuated eccentric loading (AEL), and plyometric training (PT) into resistance training programs that seek to improve an athlete’s hypertrophy, strength, and power output. Based on the existing literature, TEMPO may be best implemented with weaker athletes to benefit positional strength and hypertrophy due to the time under tension. FIT may provide an effective hypertrophy, strength, and power stimulus for untrained and weaker individuals; however, stronger individuals may not receive the same eccentric (ECC) …

The Influence Of Strength In Load-Velocity Relationships In The Back Squat, Thaddeus Light

The Association Of Handgrip Strength And Mortality: What Does It Tell Us And What Can We Do With It?, Samuel L. Buckner, Scott J. Dankel, Zachary W. Bell, Takashi Abe, Jeremy P. Loenneke

Faculty and Student Publications

© Copyright 2019, Mary Ann Liebert, Inc., publishers 2019. The relationship between grip strength and mortality is often used to underscore the importance of resistance exercise in physical activity guidelines. However, grip strength does not appear to appreciably change following traditional resistance training. Thus, grip strength could be considered reflective of strength independent of resistance exercise. If true, grip strength is not necessarily informing us of the importance of resistance exercise as an adult, but potentially highlighting inherent differences between individuals who are stronger at "baseline" compared to their weaker counterpart. The purpose of this article is to discuss: (1) …

An Examination Of The Effects Of Bilateral And Unilateral Very Short-Term Dcer Training On Strength And Neuromuscular Responses Within The Lower Limb Bilateral Deficit, Mark Travis Byrd

Theses and Dissertations--Kinesiology and Health Promotion

The very short-term resistance training (VST) model, utilizing only 2-3 training sessions, has been used to examine early phase skeletal muscle, neural, and performance adaptations. The VST model has previously been used to examine these early phase adaptations in bilateral and unilateral, isometric, isokinetic, and dynamic muscle actions in the limbs of the upper- and lower-body. The bilateral deficit (BLD) is a phenomenon in which the sum of the forces produced unilaterally is greater than the force produced bilaterally during maximal contraction of the limbs. The appearance of a bilateral deficit has been be related to various factors; including training …
