Nelson and published by . This book was released on 2017 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple ingredient pre-workout supplements (MIPS) are purported to offer favorable acute metabolic changes potentially leading to improvements in body composition over time. However, there is limited information available regarding the long-term benefits, specifically in female populations. Therefore, the purpose of this study was to investigate the long term effects of MIPS on body composition and resting energy expenditure (REE) in recreationally active females participating in a resistance training (RT) program. Nineteen females participated in a randomized, double-blind, placebo controlled study. Experimental testing included body composition and REE measurements before and after a seven-week RT program while ingesting either a MIPS or placebo daily. Subjects were further instructed to follow dietary intake recommendations to elicit moderate weight loss. There were no significant group x time interactions for body fat percentage (p=0.66), fat-free mass (p=0.87), fat mass (p=0.63), REE (p=0.52), or respiratory exchange ratio (p=0.40). Significant overall main effects for time were observed between pre and midway testing for increases in fat-free mass (p

This book was released on 2017 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consuming a multi-ingredient pre-workout supplement (MIPS) to enhance physical capabilities has become increasingly popular. However limited data is available regarding the long term safety of consuming such products. Therefore, the purpose of this study was to examine the effects of pre-workout supplementation on health measurements in recreationally active females. Subjects reported to the laboratory for baseline and identical post-data measurements which included blood pressure, heart rate, and blood lipids. They were then randomly assigned to ingest one serving of the pre-workout supplement or placebo daily during a 7-week period. All subjects also completed a standardized strength training program 3 times per week and were provided dietary recommendations. No significant group x time interactions were observed for heart rate (p=0.43), systolic blood pressure (p=0.18), diastolic blood pressure (p=0.20), high density lipoproteins (p=0.92), low density lipoproteins (p=0.93), triglycerides (p=0.96), or total cholesterol (p=0.99). There was a significant main effect for time observed for diastolic blood pressure which decreased over the course of the study (p ≤ 0.001). Ingesting a MIPS for 7 weeks does not appear to negatively influence clinical markers of health in active females.

This book was released on 2017 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-ingredient pre-workout supplements (MIPS) are popularly used to enhance exercise performance, but little is known regarding the long term effects. Further, limited data are available in female populations. Therefore, the purpose of this study was to examine the long-term effects of a MIPS on training adaptations in active females. Nineteen females participated in a randomized, double-blind, placebo controlled study. Participants completed a seven-week strength training program and followed dietary recommendations. Subjects reported to the laboratory for identical baseline and post-training testing sessions. Lower body power was assessed using a counter-movement vertical jump. Upper body and lower body strength were assessed by one-repetition maximum (1 RM) on the bench press and leg press. Muscular endurance tests were assessed on the bench press and leg press by performing a set to failure at 75% of calculated 1 RM. Both groups showed significant improvement in upper body strength (p=0.00) and lower body strength (p=0.00), but were not significantly different from each other for upper body (p=0.74) or lower body (p=0.53). There were no significant improvements for lower body power (p=0.86), upper body endurance (p=0.39), or lower body endurance (p=0.37). In conclusion, this study suggests that consumption of a MIPS does not significantly influence training adaptations.

This book was released on 2016 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-ingredient pre-workout supplements (MIPS) are consumed with the belief of enhancing exercise performance, but research has primarily dealt with male subjects. The purpose of this study was to examine the acute effects of ingesting a MIPS on active females. Fifteen females participated in a randomized, double-blind, placebo controlled cross-over design study. Subjects reported to the laboratory for a familiarization, baseline, and two experimental testing sessions. Experimental testing included REB, heart rate, and blood pressure. Also, muscular endurance was assessed by performing a set to failure on back squat and bench press (BP) at 85% of their 5-repetition maximum. Anaerobic power was assessed using a counter-movement vertical jump test and a nonmotorized fOrce treadmill sprint test. Subjective measurements were assessed using a 5- point Likert scale. A significant main effect for condition was observed for REE (p~0.021), diastolic blood pressure (p~O.Oil), BP repetitions (p=0.037), and total work (p=0.039) following ingestion of the MIPS. A significant condition x time interaction was observed regarding feelings of fOcus at 80-minutes post ingestion (p=0.046). In conclusion, the current study suggests that consumption of a MIPS significantly increased REE, diastolic blood pressure, upper body muscular endurance, total work completed, and produced an increase in feelings of focus.
Download or read book Effects of Pre workout Supplementation on Core Temperature and Metabolic Rate During Exercise written by Steven J. Czerniejewski and published by . This book was released on 2020 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The aim of this study was to examine the effect of energy supplementation on exercise performance, body temperature, and metabolic rate during exercise. Recreationally active males ages 18-35 (N = 10) participated in three cycle ergometer trials, energy supplement (S), placebo (P), and water (W). Seven ANOVAs were conducted to find no statistically significant changes across each condition among oxygen consumption (VO2), heart rate (HR), core temperature (T), metabolic rate (MR), average power, and blood pressure. Slight differences did exist in that MR was greatest in the S group (12.37 ± 3.65 kcal/min) compared to W (11.96 ± 3.58 kcal/min) and P (12.31 ± 2.42 kcal/min) without a concurrent increase in T (37.77 ± 0.76 oC, 36.75 ± 0.59 oC, and 37.85 ± 0.26 oC respectively) may indicate preworkout supplementation could increase work output without compromising the bodies ability to dissipate heat.
Download or read book Effects of 28 Days of Beta alanine and Creatine Monohydrate Supplementation on Muscle Carnosine Body Composition and Exercise Performance in Recreationally Active Females written by Julie Yong Kresta and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Early research with beta-alanine (beta-ALA) supplementation has shown increases in muscle carnosine as well as improvements in body composition, exercise performance and blood lactate levels. Creatine monohydrate supplementation has been extensively researched for its effects on anaerobic exercise performance. Recently, a new line of studies have examined the combined effects beta-ALA and creatine supplementation on anaerobic exercise performance and lactate threshold. The purpose of the present study is to examine the acute and chronic effects of beta-ALA supplementation with and without creatine monohydrate on body composition, aerobic and anaerobic exercise performance, and muscle carnosine and phosphagen levels in college-aged recreationally active females. Thirty-two females were randomized in a double-blind placebo controlled manner into one of four supplementation groups including beta-ALA only, creatine only, beta-ALA and creatine combined and placebo. Participants supplemented for four weeks and reported for testing at baseline, day 7 and day 28. Testing sessions consisted of a resting muscle biopsy of the vastus lateralis, body composition measurements, a graded exercise test on the cycle ergometer for VO2max and lactate threshold, and multiple Wingate tests for anaerobic exercise performance. Results showed all supplementation strategies increasing muscle carnosine levels over placebo after four weeks, but not between groups. Muscle creatine increased for all groups after four weeks, but not between groups. There were improvements for all groups with body composition after four weeks, despite the present study not including a specific training protocol. There were no group differences observed for aerobic exercise, blood lactate levels, lactate threshold, ventilatory threshold, peak power, mean power, total work or rate of fatigue. There were some trends for anaerobic exercise indicating groups supplementing with creatine may have greater improvements, however, these findings were not statistically significant. The present study failed to show any additive effects of beta-ALA and creatine supplementation for body composition, aerobic exercise, lactate threshold or anaerobic exercise measures. This could be due to the small sample size resulting in low power and effect sizes. Previous research has demonstrated that four weeks of beta-ALA and creatine supplementation was enough time to increase muscle carnosine and phosphagen levels. However, perhaps more time is needed for performance adaptations to occur, especially without the addition of an exercise training component.
Download or read book The Effects of Beta Alanine Supplementation and High Intensity Interval Training on Body Composition VO2 Peak and Critical Power in Recreationally Active Females written by Rebekah Macker and published by . This book was released on 2018 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Beta-alanine (BA) is a non-essential amino acid and has been used as a nutritional ergogenic aid that previous research has claimed to increase muscle carnosine. In addition, research studies have shown that BA decreases feelings of fatigue through its buffering capacity and may possibly enhance training capacity. The aim of this study was to determine whether 4 weeks of BA supplementation combined with a running HIIT workout would improve VO2peak and time during a graded exercise test, as well as peak power (PP) and mean power (AP) during a critical power test for college-aged recreationally active females. A second aim of this study was to determine if the supplementation of BA combined with the running HIIT would improve anthropometric data, lean mass, fat mass, and body fat percentage. Seven recreationally active females completed the study and were randomly assigned to one of three groups, BA (n=3), placebo (PLA; n=2), or a control group (CON; n=2). Body composition was measured for all participants before and after the 4-week intervention along with a graded exercise test to determine VO2peak on a treadmill and an all out cycling test to determine power output on a cycle ergometer. The PLA and BA group completed HIIT 2 days per week on a treadmill while additionally consuming 16.5g of dextrose or 1.5g of BA + 15g of dextrose 4 times daily for the 28 days. The treadmill remained at a constant 5.3% grade while participants performed 4 x 4 minutes of work at 90-95% HRmax with 3 minutes of rest at 75% HRmax. There were no significant differences between groups or significant improvements found as a result of this study. Regardless of group participation here was a decrease in time to exhaustion from pre to post testing however these results were not significant. The results of this study suggest that BA does not have any additional effect on body composition or exercise performance within this sample.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Background: The cardiovascular (CV) and metabolic health benefits or risks associated with consumption of multi-ingredient performance enhancing supplements (MIPS) in conjunction with periodized resistance training (RT) in resistance trained men are unknown. This population is a major target audience for performance supplements, and therefore, the purpose of this study was to investigate the combined effect of RT and commercially available pre- and post-exercise performance supplements, NO-Shotgun® (SHOT) and NO-Synthesize® (SYN), respectively, on CV risk and body composition in resistance trained men. Methods- Twenty-four resistance trained men completed 6 weeks (3 times/week) of whole-body periodized RT while either ingesting SHOT 30 min pre-exercise and SYN immediately post-exercise or an isocaloric maltodextrin placebo (PL) 30 min pre-exercise and immediately post-exercise. Before and after 6 weeks of RT and supplementation, resting heart rate (HR), blood pressures (BP), total body fat, android fat, gynoid fat, fat-free mass (FFM) and fasting blood measures of glucose, lipids, nitrate/nitrite (NOx), cortisol, and high sensitivity C-reactive protein (CRP) were measured. Statistical analysis was conducted using a 2 x 2 (group x time) repeated measures ANOVA. Significance was set at p

This book was released on 2013-11-13 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.
Download or read book Effects of Beta alanine Supplementation and High Intensity Interval Training Among Recreationally Active Females written by Mary E. Yarbrough and published by . This book was released on 2016 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Beta-alanine is a non-essential amino acid that when combined with L-histidine forms the dipeptide carnosine. Recent research has shown that supplementary intake of beta-alanine can substantially increase carnosine content in muscle fibers and has been associated with attenuating fatigue and enhancing high intensity exercise performance. The aim of this study was to examine the effects of 4 weeks of beta-alanine supplementation combined with high intensity interval training (HIIT) on indices of aerobic and anaerobic performance, rowing performance, and body composition. Twenty-one recreationally active females (22.2 ± 2.2 yrs.) participated in a double blind, placebo controlled study and were randomly assigned to one of 3 groups: beta-alanine (BA, n = 8), placebo (PLA, n = 7), or control (CON, n = 6). Prior to and following 4 weeks of supplementation all groups had anthropometric measurements done and body composition was determined using dual energy x-ray absorptiometry (DEXA). Participants also performed a graded exercise test on the rowing ergometer to determine VO2 peak, ventilatory threshold (VT), and time to exhaustion (TTE). Additionally, participants came back to the lab to complete a 1,000 m time trial (TT) to determine time for completion and peak power output (PPO). During the 4 week intervention the BA and PLA groups completed a 7 minute 1: 1 (work: recovery) HIIT protocol that was a pre-determined workload whilst consuming either 6.4 g/day of BA or PLA. All three groups showed significant improvements from pre to post testing in VO2 peak, TTE, VT, TT, PPO and a reduction in total BF% in arms (p ≤ 0.05). While several of the variables had significant interactions between groups: VO2 peak, TTE, TT, PPO, BF% legs, and BF% trunk, (p ≤ 0.05), post hoc testing revealed that peak power output was the only the variable that showed a significant difference between the BA and PLA groups as compared to the CON group during post testing (p = 0.00). The results of this study suggest that HIIT can enhance measures of aerobic capacity and increase PPO, while beta-alanine supplementation did not seem to have much of an effect on training.
