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 …

Neighborhood Socioeconomic Environment And Its Influence On Cardiorespiratory Fitness And Physical Activity In Youth, Morgan N. Clennin

Theses and Dissertations

Among youth, inadequate cardiorespiratory fitness and physical inactivity are powerful markers of health associated with numerous health outcomes across the lifespan. Unfortunately, a majority of U.S. youth have inadequate cardiorespiratory fitness levels and do not meet physical activity guidelines. While previous research has identified several individual-level factors associated with youth cardiorespiratory fitness and physical activity, environmental factors have been increasingly recognized. Of particular interest is the neighborhood socioeconomic environment, which has been consistently associated with several health outcomes among adults. However, little is known regarding the relationship between the neighborhood socioeconomic environment, cardiorespiratory fitness, and physical activity among younger populations. …

The Predictability Of Peak Oxygen Consumption Using Submaximal Ratings Of Perceived Exertion In Adolescents, Danilo V. Tolusso, Ward C. Dobbs, Michael Esco

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 1173-1183, 2018. Rating of perceived exertion (RPE) extrapolation involves mathematically extending the submaximal relationship between RPE and oxygen consumption (VO₂) to maximal intensity. This technique allows practitioners to forego, potentially dangerous, maximal exertion testing while attaining accurate measures of maximal oxygen consumption used for exercise prescription. This method has been proven accurate in adults, but much less in known when applied to an adolescent population. The purpose of this study was to assess the accuracy of the RPE extrapolation as method for estimating VO_2max in adolescents. Twenty-two healthy, asymptomatic adolescents performed …

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 1156-1172, 2018. This study characterized both aerobic and anaerobic energy expenditure (EE) for several Polynesian dances in a group of experienced professional Polynesian dancers. Thirteen men and 17 women were tested using indirect calorimetry to assess aerobic EE (and converted to METs), and fingertip blood lactate to estimate anaerobic EE, during both resting and dancing activities. Total EE was then computed as the sum of both aerobic and anaerobic activity energy expenditure (AEE, or EE above resting). One sample t-tests compared mean MET values for each type of dance to the 3-MET and 6-MET …

Foot-To-Foot Bioelectrical Impedance, Air Displacement Plethysmography, And Dual Energy X-Ray Absorptiometry In Resistance-Trained Men And Women, Justin Merrigan, Sina Gallo Phd, Jennifer Fields, Margaret T. Jones Phd

International Journal of Exercise Science

International Journal of Exercise Science 11(4): 1145-1155, 2018. Accurate assessment of body composition is important to athletic performance goal setting and nutritional program design. Dual-energy x-ray absorptiometry (DXA) is considered the “gold standard” in body composition assessment, yet the cost renders DXA unfeasible for many. Therefore, it is of interest to compare other body composition assessment methods to DXA in resistance-trained individuals whose focus is athletic performance. The purpose of the current study was to determine the agreement in estimates of body composition ((body fat (BF%); fat mass (FM); fat free mass (FFM)) by bioelectrical impedance analysis (BIA; Tanita SC-331S) …

The purpose was to determine if the Alu-insertion (I)/deletion (D) polymorphism of the tissue plasminogen activator (tPA) gene influences the tPA response to maximal exercise. Fifty male subjects (age = 23.6 ± 4.7 yrs) completed a maximal treadmill exercise test. Blood samples were drawn before and immediately after exercise for determination of plasma tPA antigen and activity. Isolated DNA was amplified via polymerase chain reaction, electrophoresed, and visually amplified to determine tPA genotype. Subjects were classified as possessing the D allele (D) (n = 28) or being homozygous for the I allele …

Effects Of Stretching Vs. Self-Myofascial Release On Ankle, Hip, And Shoulder Flexion, Trent S. Edwards

Student Theses and Dissertations

Deficits in range of motion can hinder performance, lead to more issues and prohibit some individuals from doing basic, everyday tasks. Stretching is one way people attempt to increase their range of motion. Self- myofascial release is a newer way of achieving increases in range of motion. Self-Myofascial Release (SMR) has been shown to increase ROM (Blandpied & Dorfman, 2014). However, use of a foam roller produced suboptimal SMR due to inadequate pressure on the roller (Evans, 2014). One solution to this problem would be to create additional pressure using a smaller, more targeted device of denser material. The current …

Effects Of Protein Supplementation On Performance And Recovery In Resistance And Endurance Training, Harry P. Cintineo, Michelle A. Arent, Jose Antonio, Shawn M. Arent Ph.D., Cscs*D, Fissn, Facsm, Fnak

Faculty Publications

There is robust evidence which shows that consuming protein pre- and/or post-workout induces a significant rise in muscle protein synthesis. It should be noted, however, that total daily caloric and protein intake over the long term play the most crucial dietary roles in facilitating adaptations to exercise. However, once these factors are accounted for, it appears that peri-exercise protein intake, particularly in the post-training period, plays a potentially useful role in terms of optimizing physical performance and positively influencing the subsequent recovery processes for both resistance training and endurance exercise. Factors that affect the utility of pre- or post-workout feeding …

Association Between Subjective Indicators Of Recovery Status And Heart Rate Variability Among Divison-1 Sprint-Swimmers, Andrew A. Flatt, Michael R. Esco, Fabio Y. Nakamura

Health Sciences & Kinesiology: Faculty Publications

Heart rate variability (HRV) is a physiological marker of training adaptation among athletes. However, HRV interpretation is challenging when assessed in isolation due to its sensitivity to various training and non-training-related factors. The purpose of this study was to determine the association between athlete-self report measures of recovery (ASRM) and HRV throughout a preparatory training period. Ultra-short natural logarithm of the root mean square of successive differences (LnRMSSD) and subjective ratings of sleep quality, fatigue, muscle soreness, stress and mood were acquired daily for 4 weeks among Division-1 sprint-swimmers (n = 17 males). ASRM were converted to z-scores …

Terrestrial Locomotion Of The Northern Elephant Seal (Mirounga Angustirostris): Limitation Of Large Aquatically Adapted Seals On Land?, Kelsey A. Tennett, Daniel P. Costa, Anthony J. Nicastro, Frank E. Fish

Biology Student Work

The aquatic specializations of phocid seals have restricted their ability to locomote on land. The amphibious northern elephant seal, Mirounga angustirostris, is the second largest phocid seal in the world, with males reaching 2700 kg. Although elephant seals are proficient swimmers and deep divers, their extreme size and aquatic specializations limit terrestrial movement. The kinematics of terrestrial locomotion in northern elephant seals were analyzed from video recordings of animals observed on the beach of Añ o Nuevo State Reserve, CA, USA. The seals moved using a series of rhythmic undulations produced by dorsoventral spinal flexion. The traveling spinal wave moved …
