This study investigated the effect of branched-chain amino acid (BCAA) supplementation on recovery from eccentric exercise. Twenty males ingested either a BCAA supplement or placebo (PLCB) prior to and following eccentric exercise. Creatine kinase (CK), vertical jump (VJ), maximal voluntary isometric contraction (MVIC), jump squat (JS) and perceived soreness were assessed. No significant (p > 0.05) group by time interaction effects were observed for CK, soreness, MVIC, VJ, or JS. CK concentrations were elevated above baseline (p < 0.001) in both groups at 4, 24, 48 and 72 hr, while CK was lower (p = 0.02) in the BCAA group at 48 hr compared to PLCB. Soreness increased significantly from baseline (p < 0.01) in both groups at all time-points; however, BCAA supplemented individuals reported less soreness (p < 0.01) at the 48 and 72 hr time-points. MVIC force output returned to baseline levels (p > 0.05) at 24, 48 and 72 hr for BCAA individuals. No significant difference between groups (p > 0.05) was detected for VJ or JS. BCAA …

Muscle Adaptations To High-Load Training And Very Low-Load Training With And Without Blood Flow Restriction, Matthew B. Jessee, Samuel L. Buckner, J. Grant Mouser, Kevin T. Mattocks, Scott J. Dankel, Takashi Abe, Zachary W. Bell, John P. Bentley, Jeremy P. Loenneke

Faculty Scholarship

An inability to lift loads great enough to disrupt muscular blood flow may impair the ability to fatigue muscles, compromising the hypertrophic response. It is unknown what level of blood flow restriction (BFR) pressure, if any, is necessary to reach failure at very low-loads [i.e., 15% one-repetition maximum (1RM)]. The purpose of this study was to investigate muscular adaptations following resistance training with a very low-load alone (15/0), with moderate BFR (15/40), or with high BFR (15/80), and compare them to traditional high-load (70/0) resistance training. Using a within/between subject design, healthy young participants (n = 40) performed four …

Multi-Ingredient Pre-Workout Supplements, Safety Implications, And Performance Outcomes: A Brief Review, Patrick S. Harty, Hannah A. Zabriskie, Jacob L. Erickson, Paul E. Molling, Chad M. Kerksick, Andrew R. Jagim

Faculty Scholarship

In recent years, a new class of dietary supplements called multi-ingredient pre-workout supplements (MIPS) has increased in popularity. These supplements are intended to be taken prior to exercise and typically contain a blend of ingredients such as caffeine, creatine, beta-alanine, amino acids, and nitric oxide agents, the combination of which may elicit a synergistic effect on acute exercise performance and subsequent training adaptations compared to single ingredients alone. Therefore, the purpose of this article was to review the theoretical rationale and available scientific evidence assessing the potential ergogenic value of acute and chronic ingestion of MIPS, to address potential safety …

Resistance training and maintenance of a higher protein diet have been recommended to help older individuals maintain muscle mass. This study examined whether adherence to a higher protein diet while participating in a resistance-based exercise program promoted more favorable changes in body composition, markers of health, and/or functional capacity in older females in comparison to following a traditional higher carbohydrate diet or exercise training alone with no diet intervention. In total, 54 overweight and obese females (65.9 ± 4.7 years; 78.7 ± 11 kg, 30.5 ± 4.1 kg/m², 43.5 ± 3.6% fat) were randomly assigned to an exercise-only …

Nutrition Knowledge Among Adolescent Athletes, Caregivers, And Coaches, Ann-Kathrin Puschkasch

Theses

The thesis, Nutrition Knowledge Among Adolescent Athletes, Caregivers, and Coaches, explores the nutritional knowledge of these three groups and highlights gaps that may impact young athletes' performance and health. Conducted in Missouri, the study used customized online surveys to evaluate participants' understanding of general and sports nutrition, including macronutrients, hydration, and supplementation. A total of 306 participants, comprising 47 athletes, 117 caregivers, and 142 coaches, completed the surveys.

Findings revealed significant gaps in knowledge across all groups, though coaches scored the highest, followed by caregivers and then athletes. For example, many athletes lacked awareness of basic nutritional concepts like …

Effects Of Triphasic Training On Strength And Power On Men's Volleyball Players, Grant Kastelan

Theses

Triphasic training is a method popularized by Cal Dietz (Dietz & Peterson, 2012) which includes three different phases: accumulation, transmutation, and realization. Different goals are set for each phase with power development being the overarching theme. During the accumulation phase, the training block is split into the three muscle actions eccentric, isometric, and concentric. During each phase, one action is the emphasis of the program. The purpose of this study was to examine the effects of the accumulation phase of the triphasic training program on collegiate men's volleyball players I-Repetition Max strength, vertical jump, and isometric force. Additionally, the researcher …

Effects On Muscular Strength And Muscular Power While Using Weighted-Chains During A 4-Week Bench Press Resistance-Training Program, Richard Stecker

Theses

This study investigates the effects of weighted chains on muscular strength and power during a four-week bench press resistance-training program in recreationally trained college-aged men. The research addresses a gap in the literature regarding the effectiveness of chain-loaded resistance as a method to enhance upper body performance, particularly in the bench press. Thirty healthy males aged 18–40 with a minimum of two years of training experience were randomly assigned to one of three groups: a weighted-chains group (60% 1RM: 40% bar weight, 20% chain), a top-weight-matched group (60% 1RM with no chains), and a bottom-weight-matched group (40% 1RM with no …

Effect Of Long-Term Beta-Alanine Supplementation On Performance In Male Collegiate Rugby Athletes, Charles Smith

Theses

This study investigated the effects of six weeks of beta-alanine (BA) supplementation on the anaerobic performance of collegiate male rugby players. Beta-alanine is a precursor to carnosine, an intramuscular buffer that helps maintain pH during high-intensity exercise. Rugby is a sport characterized by repeated bouts of high-intensity efforts, making it a prime candidate to benefit from improved buffering capacity.

Twenty-one male rugby players were recruited for the double-blind, placebo-controlled study, with 16 completing the post-testing. Participants were randomly assigned to either a beta-alanine group (6.4 g/day) or a placebo group (6.4 g/day of maltodextrin). Both groups continued their normal team …

The Relationship Between Lower Extremity Strength, Mobility, Movement Quality, And Pain In Collegiate Synchronized Swimmers, Paul Borges Costa
