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.

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.

Download or read book The Effects of Carbohydrate protein Supplementation on Endurance Exercise Performance Recovery and Training Adaptation written by Lisa Ferguson Stegall and published by . This book was released on 2010 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent research suggests that adding protein (PRO) to a carbohydrate (CHO) supplement can have substantial benefits for endurance exercise performance and recovery beyond that of CHO alone. CHO+PRO supplements are often commercially available formulations consisting of carbohydrates (dextrose, maltodextrin) and whey protein. The effects of a supplement containing moderate protein and a low-CHO mixture on endurance performance has not been investigated. Also, the effects of CHO+PRO supplementation in the form of a natural food, flavored milk, on measures of recovery from acute endurance exercise, as well as on chronic aerobic exercise training adaptations, have not been characterized. Therefore, in this series of four studies, the effects of CHO+PRO supplementation on the following areas of endurance exercise performance, recovery, and adaptation are investigated: acute endurance exercise performance, inflammatory and muscle damage markers, muscle glycogen resynthesis, activation of signaling proteins involved in the initiation of protein synthesis and degradation, subsequent endurance exercise performance, and chronic aerobic training adaptations (maximal oxygen consumption, oxidative enzyme activity, body composition, immune cell levels, and inflammatory markers). Study 1 demonstrated that a supplement containing a low-CHO mixture plus moderate protein significantly improved aerobic endurance when cycling at or below the ventilatory threshold, despite containing 50% less CHO and 30% fewer calories relative to a higher CHO beverage. Study 2 demonstrated that CHO+PRO supplementation in the form of chocolate milk (CM) is an effective post-exercise supplement that can improve subsequent performance and provide a greater intracellular signaling stimulus for protein synthesis compared to CHO and placebo. Study 3 found that post-exercise CM supplementation during 4.5 wks of aerobic exercise training improves the magnitude of cardiovascular adaptations more effectively than isocaloric CHO or placebo, while the fourth study demonstrated that post-exercise CM supplementation during 4.5 wks of aerobic training improves body composition more effectively than isocaloric CHO or placebo. The fourth study also demonstrated that 4.5 wks of training does not appear to perturb resting immune cell concentrations or markers of inflammation and muscle damage. Taken together, the results of this research series suggest that CHO+PRO supplementation extends endurance performance, improves recovery, and increases training adaptations more effectively than CHO or placebo.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eccentric exercise often results in the production of markers of oxidative stress and an inflammatory response, which leads to delayed onset muscle soreness (DOMS). DOMS is associated with impaired muscular performance. Dietary interventions may reduce inflammation and improve physical performance. The first aim of this investigation was to determine if Acai supplementation reduces markers of oxidative stress and the inflammatory process caused by eccentric exercise. The second aim was to determine if Acai supplementation reduces muscle soreness and improves muscle function. Individuals were counterbalanced/stratified into the Acai group or a placebo group. Supplementation started 48 hours prior to downhill running. Markers of oxidative stress and inflammation, and range of motion, muscle soreness perception, agility, and vertical jump displacement were assessed at baseline, after, 24, and 48 hours after downhill running. Twenty collegiate athletes and non-athletes (21±2 years old) completed the protocol. The Acai group (N = 10) reported significantly less muscle soreness in the quadriceps muscle (p = .011) compared to the placebo group (N = 10). In addition, there was a significant difference (p = .023) in the group by time interaction in the quadriceps muscle soreness. Furthermore, the Acai group scored slightly different on range of motion, agility, vertical jump displacement, creatine kinase, and c-reactive levels compared to the placebo group throughout all 4 time periods. Acai has demonstrated to be an effective supplement to decrease quadriceps muscle soreness after downhill running. Furthermore, the consistency of results throughout the 4 time periods may suggest its potential to slightly change performance and levels of oxidative stress and inflammation.

Book excerpt: "Purpose: To investigate the effects of an acute multi-nutrient supplement on game-based exercise performance, peak power output, anaerobic by-products, hormonal profilers, markers of muscle damage and perceived muscular soreness prior to, immediately post and 24 hr following rugby union competition. ... Conclusions: These findings suggest SUPP [multi-nutrient supplement] may assist in the maintenance of VHIR [very high intensity running] during rugby union matches, possibly via the buffering qualities of ingredients. Correlations between increased work completed at very high intensities and muscular degradation in SUPP conditions however, mask the anti-catabolic properties of the SUPP."-- Abstract.

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 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 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose To compare the effect of milk based protein-carbohydrate beverage (MP-CHO) and a carbohydrate only beverage (CHO) immediately following Gaelic football match play on markers of muscle damage and inflammation, muscle soreness and sprint performance. Methods Male Gaelic football players with a mean age of 17.4 years played a competitive Gaelic football game after which they consumed a 500 mL of either a MP-CHO beverage or a CHO only beverage. Blood samples were taken and subjective muscle soreness was measured before, immediately post-game and at 12 h, 36 h and 60 h post-game. Sprint performance was measured pre-game and at 12 h, 36 h and 60 h post-game. Heart rate and movement patterns were continuously measured using telemetry and GPS tracking, respectively. Results Measured activity characteristics and impact zones were similar in MP-CHO and CHO during match-play. No significant main effect for group or interaction effects between time and group was observed for CK, circulating leukocytes, muscle soreness or 5 m and 20 m sprint times. Creatine kinase (CK) levels were elevated (p

This book was released on 2013 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate the effects of 6 weeks of hydroxytyrosol (HT) supplementation on markers of muscle damage in healthy, recreationally active men before and throughout acute aerobic exercise bouts. Using a randomized, double-blind, repeated-measures, placebo-controlled design, sixty-one (n = 61) subjects (21.46 ± 0.22 yrs, 179.46 ± 0.79 cm, 78.91 ± 1.19 kg) consumed either a high dose (HI) HT supplement (150 mg HT), a low dose (LO) HT supplement (50 mg HT), or a placebo (PLA) every day for 6 weeks. Throughout the course of the study, the subjects performed four time trial rides (TT1-TT4) on a cycle ergometer. TT1 occurred before supplementation, TT2 halfway through the supplementation period, and TT3 and TT4 occurred in the sixth week and final two days of supplementation. Blood was drawn prior to (pre) and just before termination (end) of each time trial to measure markers of muscle damage during exercise. We observed that endurance exercise increased indicators of muscle damage, CPK and myoglobin, but an association between HT treatment and reduced muscle damage indicators during exercise were not demonstrated. However, the HT supplementation for 6 weeks in recreationally-active males improved time trial performance in the HT treatment groups over the course of the study and this improvement was accompanied by a lower increase in myoglobin concentration in blood in the HI treatment group than in the LO treatment group. Also, performance was improved after 6 weeks in the PLA group. This improvement was associated with an increase in rating of perceived exertion (RPE). RPE was not increased in either the LO and HI treatment groups, although time trial performance was significantly improved. It is possible that HT can improve performance by altering perception of effort. We conclude that chronic and acute HT supplementation did not reduce markers of muscle damage in this population at rest, during, or following exercise, but improved aerobic performance.

Download or read book The Role of Protein Following Intense Exercise in Competitive Youth Athletes written by Brandon McKinlay and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall purpose of this thesis was to examine the role of post-exercise dairy protein consumption (isolated and whole-food) on recovery indices (performance and muscle damage) and inflammation following intense exercise within the context of different ecologically valid sporting environments, i.e., acute competition and a short-term period of intensified training, in competitive youth athletes. For this, two studies were conducted. Study 1 (Chapter 3) investigated the effect of whey protein consumption following a high-intensity interval swim session (HIIS) among adolescent swimmers on subsequent performance, muscle soreness, plasma creatine kinase and inflammatory cytokines, compared with isoenergetic carbohydrate and flavoured water in the acute (0-8 h) and short-term (8-24 h) recovery periods. Study 2 (Chapter 4) examined the effects of increased protein consumption, via plain Greek yogurt, compared with an isoenergetic carbohydrate control on performance recovery, inflammation, and muscle damage, during a 5-day simulated soccer training camp in competitive adolescent female soccer players. The collective findings indicate that during both acute and short-term periods of intensified exercise, the provision of dairy protein regardless of form (isolated or whole food), provided no added benefit at enhancing performance recovery or ameliorating muscle damage above that of energy matched carbohydrates. However, it does appear that the consumption of calories, regardless of type (e.g., carbohydrates or dairy protein), when rapid recovery is required, offers greater performance retainment than water. Therefore, during periods of intensified exercise that may be accompanied by inadequate recovery, the replenishment of energy should be the primary focus. Further, in both studies the consumption of dairy protein following exercise leads to an augmented anti-inflammatory response (i.e., increased IL10), not observed in the control conditions (i.e., water or energy-matched carbohydrates). Thus, it is possible that dairy protein consumption post-exercise may benefit the acute immune response. This possibility requires further study.

This book was released on 2011 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: The purpose of the present study was to investigate indices of muscle damage and recovery in novice runners following completion of a marathon, and compare responses in these indices when receiving carbohydrate (CHO) or carbohydrate-protein (CHO+Pro) supplementation during the marathon run. Methods: 16 subjects were arranged into matched-pairs based on muscle damage responses; determined by serum kinase (CK) levels following an 18-mile training run. Subjects' perceived ratings of muscle soreness and mental/physical energy/fatigue, maximal isometric force of the leg extensors (MVC), and serum CK were measured on three occasions: prior to the marathon, 24 hours post-marathon and 72 hours post-marathon. During the 26.2-mile marathon run, subjects consumed energy gels (100 kcal/packet) at four-mile intervals throughout the event. Members of each matched-pair were assigned to a CHO (25 g CHO) or CHO+Pro (20 g CHO, 5 g Pro) gel in a randomly counterbalanced design. Results: Significant declines in MVC, and mental energy ratings were observed 24-hours post-marathon, with significant increases in serum CK, muscle soreness, and physical fatigue ratings. These responses were attenuated by 72 hours post-marathon (in comparison to 24-hour levels), but serum CK and perceived muscle soreness remained significantly different from pre-marathon levels. No significant differences were observed between CHO and CHO+Pro treatments for any of the muscle recovery variables studied. Conclusions: Marathon running results in significant impairment in skeletal muscle function, soreness/fatigue, and elevated markers of sarcolemmal damage for at least 72 hours post-event. CHO+Pro ingestion during the marathon does not appear to influence post-marathon muscle recovery in comparison to CHO intake alone.
