Download or read book The Dose Dependent Effects of Polyphenol Supplementation on Inflammatory Markers Following Eccentric Exercise written by Kevin Michael Christmas and published by . This book was released on 2012 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unaccustomed eccentric exercise can lead to decreases in muscle force production, increases in soreness, swelling, stiffness, and discomfort. The purpose of this study was to test the dose response of pomegranate juice concentrate on serum markers of muscle permeability, inflammation, and total anti-oxidant status. To test this hypothesis, 45 healthy recreationally active males (22.3 ± 0.5 y, 73.8 ± 1.71 kg, 174.9 ± 0.9 cm) were recruited from the local Austin community for participation in this study. Subjects were disqualified from participation in the study if in the past 6 months they were engaged in an exercise training program. Subjects were placed into either the placebo group, the once-daily, or twice-daily pomegranate juice concentrate supplementation group. Subjects performed a total of 8 days of supplementation. On day 4, all subjects came to the laboratory and underwent an eccentric exercise protocol consisting of 2 minutes of downhill running at -10% grade at 7.5 mph repeated 10 times, resulting in ~20 minutes of total downhill running. Thereafter, subjects performed 50 eccentric elbow extensions each lasting 5 seconds using a weight equal to their concentric one-repetition maximum. Blood measures were made pre-exercise (baseline), and 2, 24, 48, 72, and 96 hours post exercise and analyzed for interleukin-6, creatine kinase, myoglobin, and total anti-oxidant status. Creatine kinase was significantly elevated at 96 hours post exercise, but with no significant differences between treatments. Myoglobin was significantly elevated above baseline at 2 and 96 hours, but with no differences between treatments. There was no effect for time or treatment on the total anti-oxidant status of the serum. Il-6 was significantly higher at 2 and 24 hours after exercise, but with no difference between treatments. The percent increase in interleukin-6 from baseline was significantly lower in the twice-daily POM supplementation group versus placebo (124.3 ± 9.4, 188.6 ± 16.0% of baseline; respectively) during the 2-96 hours following eccentric exercise, but no statistical difference between 1x and 2x or 1x and placebo was observed. This suggests that 8 days of supplementation with pomegranate juice concentrate twice a day significantly reduces the percent increase in a marker of inflammation (interleukin-6) during the 96 hours following eccentric exercise; however, neither supplement was different than the placebo in regards to all other measures.

This book was released on 2012 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: An acute bout of unaccustomed eccentric exercise causes prolonged strength loss and delayed onset muscle soreness (DOMS) for several days. Chronic dietary supplementation with polyphenols, from pomegranates, has been shown to accelerate recovery following eccentric exercise, but the optimal dose is unknown. The purpose of this study was to determine the effect of dietary supplementation with different doses of pomegranate juice concentrate (PJC) on muscular strength, power, and soreness throughout a 96-hour time period following an acute bout of eccentric exercise. Healthy recreationally active males (n=45) were assigned to one of three treatment groups: Once-daily PJC (1x), twice-daily PJC (2x), or placebo (PLA) supplementation over a period of eight days. A 1x dose of PJC provided approximately 650 mg GAE. On day four of each treatment, subjects performed downhill running intervals ( -10% grade) over a 40-minute period followed by 40 repetitions of eccentric elbow flexion at 100% of concentric 1-RM. Muscle soreness of arms and legs, maximal isometric strength of the elbow flexors (EF) and knee extensors (KE), vertical jump height (VJ[subscript height]) maximal cycling power (P[subscript max]), and 10-meter sprint velocity (V[subscript 10m]) were assessed pre-exercise and 2, 24, 48, 72, 96 hours post-exercise. Additionally, maximal instantaneous power (IP[subscript max]), maximal velocity (V[subscript max]), maximal torque (T[subscript max]), and torque at 0° (T0) were assessed on the inertial load power cycle pre-exercise and 24, 48, 72, 96 hours post-exercise. Throughout the 96-hours post-exercise, isometric EF strength was significantly higher in 1x and 2x groups as compared to PLA (main treatment effect, 83.6 ± 2.7% vs. 85.6 ± 1.9% vs. 78.4 ± 1.8%, respectively; p

Download or read book Functional Foods written by I. Goldberg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Accuse not Nature! She has done her part; Do Thou but Thine!" Milton, Paradise Lost 1667 The concept that nature imparted to foods a health-giving and curative function is not new. Herbal teas and remedies have been used for centuries and continue in use in many parts of the world today. In modern society, we have turned to drugs to treat, miti gate, or prevent diseases. However, since the discovery of nutrients and our increasing analytical capabilities at the molecular level, we are beginning to become more knowledgeable of the biochemical structure-function relationship of the myriad of chemicals that occur naturally in foods and their effect on the human body. The holistic approach to medicine and diet that began in the 1970s has now seen a renewal as we realize that certain foods, because of the presence of specific biochemicals, can have a positive impact on an individual's health, physical well-being, and mental state. In fact, because of the negative image of drugs, and the grey area of s- xi Foreword xii plements, the use of foods that are "functional" is becoming a growth area for the food industry. In Japan this concept has led to one of the largest growing markets, where they have defined "functional foods" as regular foods derived only from naturally occurring in gredients. The Japanese further require that the functional foods be consumed as part of the diet and not in supplement form (i. e.
