Book excerpt: Background: Betalains are phytochemical pigments of red beets that have antioxidant and anti-inflammatory properties. The purpose of this study was to determine the effects of betalain-rich concentrates (BRC) containing no sugars and nitrates on exercise performance and recovery in competitive triathletes. Methods: Twenty-two (9 men and 13 women) triathletes (38 ± 11 yrs) completed two double blind, cross-over, randomized trials (BRC and placebo) separated by 7 days. Each trial was preceded by 6 days of supplementation with 50 mg of BRC or placebo, twice per day for a total of 100mg per day. On the 7th day of supplementation, exercise trials commenced 120 min after supplementation with 50mg BRC or placebo and consisted of 40 min of cycling (75±5 %VO2max) followed by a 10 km running time trial (TT). Subjects returned 24 hours later to complete a pre-exercise blood draw and a 5km running TT to assess recovery. Heart rate (HR), rate of perceived exertion (RPE), oxygen consumption (VO2), respiratory exchange ratio (RER), blood lactate, hematocrit, serum glucose and markers of muscle damage (creatine kinase [CK] and lactate dehydrogenase [LDH]) and subjective evaluations of whole body muscle soreness and fatigue (via visual analogue scales) and a brief fatigue inventory (BFI) were assessed. Results: There were no differences between treatments during the sub-maximal cycling bout at the same exercise intensity. 10km running TT duration (49.5±8.9 versus 50.8±10.3 min, p=0.03) was faster in 15 of the 22 subjects with the BRC treatment compared to placebo. Despite running faster, average HR (161.7±11.4 versus 161.9±12.4 bpm) and RPE (5.8±1.2 versus 5.7±1.1 out of 10) were not different between BRC and placebo. 5-km running TT duration 24 hours after the 10-km TT (23.2±4.4 versus 23.9±4.7 min, p=0.003) was faster in 17 of the 22 subjects with the BRC treatment compared to placebo. Average HR during the 5-km TT (166.3±12.6 versus 162.8±14.5 bpm, p=0.004) was higher with BRC treatment, but RPE (6.5±1.4 versus 6.4±1.3 out of 10) was not different between BRC and placebo. CK, a muscle damage marker, increased less (40.5±22.5 versus 49.7±21.5 UL−1, p=0.02) from pre-exercise to after the 10-km TT and fatigue increased less from the BFI (-0.05±6.1 versus 3.23±6.1, p=0.05) 24 hours after the 10-km TT with the BRC treatment. There were no differences due to treatment for VO2, or RER. Conclusion: Betalain-rich concentrate supplementation improved 10-km TT performance in competitive male and female triathletes. Improved 5-km TT performances 24h after the 10-km TT and the attenuated increase of CK and fatigue, suggest an increase in recovery, and the ability to work harder with the same effort while taking BRC.

Download or read book Effects of Betalain rich Extract Supplementation on the Physiological Response to Exercise in Competitive Runners written by Justin Scott Van Hoorebeke and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Betalain-rich extracts (BREs) are a pigment found in food sources such as beetroot and prickly pear. They have been touted for their potent anti-oxidant and anti-inflammatory properties and these properties have been studied in both healthy and diseased models. Using a randomized, double-blind, crossover design, we tested the hypothesis that BRE supplementation would decrease markers of muscle damage, muscle soreness and fatigue and thus, improve running time trial performance compared to control in competitive, male runners (n=13). Subjects were supplemented with 50 mg of BRE or 50mg of oat [beta]-glucans (control) twice per day for 7 days prior to each trial. On the day of experimentation, cardiopulmonary and metabolic measurements and markers of muscle damage were obtained at rest, during a 30 min submaximal exercise trial, and during a 5 km TT with ~3 to 5 minutes of rest between trials. Measurements were also obtained following a 15 min recovery. Compared to control, BRE treatment resulted in a 3% lower HR and an 11% lower rate of perceived exertion (p

Download or read book Free Radicals in Exercise and Aging written by Zsolt Radák and published by Human Kinetics. This book was released on 2000 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explore the emerging field of free radical biology, exercise, and aging with this definitive reference. Free Radicals in Exercise and Agingaddresses the current debate regarding whether free radicals released during exercise accelerate the aging process. It explains how free radicals can serve as important regulators of aerobic processes, and it clarifies the importance of exercise in increasing the efficiency of the antioxidant and oxidative repair systems. Mounting research data indicate that free radicals are involved in a variety of physiological and pathophysiological processes. This book focuses on exercise-induced adaptation. In general, a person's ability to adapt to internal and external changes decreases during the aging process. However, by continually exposing the body to different challenges, regular exercise triggers an adaptation process that keeps the body and mind fit. Free Radicals in Exercise and Agingelucidates the role of free radical species in regulating this process. This text is also one of the first to provide an in-depth review of skeletal muscle oxidative stress and aging. This issue is pivotal because muscle serves such a critical role in mobility and normal life. Free Radicals in Exercise and Aging shares the most current understanding of how reactive oxygen species influence the biology of skeletal muscles. It explores some of the unique characteristics that skeletal muscle displays during aging, both in terms of free radical production and with regard to antioxidant systems. The implications of this research are far-reaching. Mutation of DNA is linked very closely to cancer, and if regular exercise improves the regulation of the antioxidant systems and the oxidative damage repair system, these mechanisms may be a very important tool against this deadly disease. This research-oriented text presents the latest information on the subject. It reviews and critiques current literature and provides critical information for exercise physiologists, sports medicine specialists, sport nutritionists, and gerontologists.
