This book was released on 2014 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results: The HMB-HIIT intervention showed significant (p[less than]0.05) gains in V̇O2peak, VT, and PVT versus the CTL and HIIT group. Both HIIT and HMB-HIIT treatment groups demonstrated significant (p[less than]0.05) improvement over CTL for P[subscript peak], T[subscritp max], RCP, and PRCP with no significant difference between the treatment groups. There were no significant differences observed for any measures of body composition. An independent-samples t-test confirmed that there were no significant differences between the training volumes for the HIIT and HMB-HIIT groups. Conclusion: These findings suggest that the addition of HMB supplementation may result in greater changes in V̇O2peak and VT than HIIT alone. Therefore, in college-aged men and women, the use of HMB supplementation may enhance the benefits of HIIT on aerobic performance measures.

Download or read book The Effects of Four Weeks of High Intensity Interval Training and beta hydroxy beta methylbutyric Free Acid Supplementation on the Onset of Neuromuscular Fatigue written by Amelia Anne Miramonti and published by . This book was released on 2015 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of this study indicate that HIIT was effective in delaying the onset of fatigue, but supplementation with HMBFA in conjunction with HIIT was more effective than HIIT alone. An increase in PWCFT represents an increase in the maximal power output an individual can sustain without eliciting fatigue. Therefore, HIIT can be used to improve performance in both endurance activities as well as intermittent sports. In addition, HMBFA supplementation is a simple method that can be used to maximize the benefits of HIIT. Acknowledgments: Metabolic Technologies, Inc. provided the supplement and funding for this study.

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.

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.

Download or read book The Effects of a Reduced exertion High intensity Interval Training Protocol on Measures of Cardiovascular and Metabolic Health in Physically Inactive Individuals written by Michael Makela and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiometabolic diseases such as diabetes and cardiovascular disease are a growing threat to the quality of life of the population. Exercise is a frontline approach to treat and prevent cardiometabolic disease and its associated risk factors. The majority of individuals, however, are physically inactive and fail to meet weekly physical activity guidelines primarily due to time-constraints. High-intensity interval training (HIIT) is a time-efficient method of exercise for improving physical fitness and reducing cardiometabolic risk factors compared to moderate-intensity continuous training (MICT). Recent research indicates that the number of repetitions and duration of high-intensity intervals can be reduced without attenuation of health benefits. This study recruited nine physically inactive but otherwise healthy participants (6 female, 3 male) which engaged in a 6 week reduced-exertion HIIT protocol. Participants were assessed before and after a 2 week run-in period, and again upon completion of the exercise protocol to assess the effect on predicted aerobic capacity (VO2max), resting heart rate (HR), resting blood pressure, heart rate variability (HRV), fasting blood glucose, peak power, mean power, body mass, and body fat %. Participants improved predicted VO2max F(2,16)=6.33, p=.009, peak power F(2,16)=10.84, p=.001, and mean power F(2,16)=20.87, p=.00006, but no changes were observed in body mass, body fat %, resting HR, resting blood pressure, resting HRV, and fasting blood glucose. In conclusion, a reduced-exertion HIIT protocol with minimal time-commitment improved predicted VO2max, peak power, and mean power and is a time-efficient alternative or adjunct method of exercise for eliciting health benefits in physically inactive individuals.
