Book excerpt: The purpose of the study was to determine the separate and combined effects of creatine and caffeine supplementation during resistance training on body composition, muscle thickness and muscle performance (strength, endurance) in trained young adults. Twenty-eight participants were randomized to supplement with Creatine and Caffeine (CR-CAF; n = 9; 22 ± 4 yrs; 0.1 g·kg-1·d-1 of creatine monohydrate powder + 3 mg·kg-1·d-1 of caffeine anhydrous micronized powder); Creatine (CR; n = 7; 22 ± 4 yrs, 0.1 g·kg-1·d-1 of creatine + 3 mg·kg-1·d-1 of caffeine placebo [micronized cellulose powder]), Caffeine (CAF; n = 6; 19 ± 1 yrs, 3 mg·kg-1·d-1 of caffeine + 0.1 g·kg-1·d-1 of creatine monohydrate placebo [maltodextrin]) or placebo (PLA; n = 6; 23 ± 7 yrs, 0.1 g·kg-1·d-1 of creatine monohydrate placebo + 3 mg·kg-1·d-1 of caffeine placebo) one hour before performing resistance training for 6 weeks. Prior to and following training and supplementation, measurements were made for body composition (fat-free and fat mass by air-displacement plethysmography), muscle thickness (elbow and knee flexors and extensors by ultrasound), muscle strength (leg press and chest press by 1-repetition maximum [1-RM]) and muscle endurance (1 set of repetitions to volitional fatigue using 50% baseline 1-RM for leg press and chest press). There was a group x time interaction (p = 0.049) for knee extensor muscle thickness with the CR group experiencing an increase over time with no changes for the other groups. There were no other between group differences for any variable. In conclusion, 6 weeks of creatine and caffeine supplementation during resistance training has no effect in trained young adults.

Book excerpt: The purpose was to examine the effects of intra-workout creatine supplementation during resistance training sessions on muscle mass and exercise performance in physically active young adults. Twenty-two participants were randomized to supplement with creatine (CR: n = 13, 26.15 ± 4.66 yrs, 80.5 ± 18.07 kg, 174.50 ± 10.53 cm; 0.0055 g/kg post training set) or placebo (PLA: n = 9, 26.44 ± 5.10 yrs, 79.88 ± 19.97 kg, 175.05 ± 12.09 cm; 0.0055 g/kg post training set) during 6 weeks of resistance training (18 sets per training session). Prior to and following training and supplementation, measurements were made for muscle thickness (elbow and knee flexors and extensors, ankle plantarflexors; ultrasound), muscular power (vertical jump, medicine ball throw), muscular strength (leg press and chest press 1-repetition maximum [1-RM]) and muscular endurance (1 sets of repetitions to volitional fatigue using 50% baseline 1-RM for leg press and chest press). There were group x time interactions for leg press and chest press strength and leg press and total body endurance. The creatine group experienced a significant increase in leg press (pre 188.06 ± 88.68 kg, post 231.68 ± 89.39 kg; p
Download or read book The Effects of 8 weeks of Caffeine Supplementation on Markers of Protein Metabolism in Resistance Trained written by James Gerosa and published by . This book was released on 2017 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resistance training is performed by collegiate and recreational athletes to increase skeletal muscle fiber size and strength. The use of caffeinated beverages and supplements is common among collegiate and recreational athletes with 85% of people aged 18-24 consuming caffeine. The use of caffeine may influence the adaptations to resistance training by altering protein metabolism. PURPOSE: To determine if caffeine intake will alter markers of protein metabolism, strength gains, or body composition in response to resistance training in resistance trained young adult males during an 8-wk training protocol. METHODS: Resistance trained males (n=20, 22.1±2.4 y; 178.1±7.5 cm; 82.8±15.7 kg) were randomly assigned into a caffeine (CAF; n=10) or placebo supplementation group (PLA; n=10). Participants were instructed to consume three caffeine (200 mg per capsule; 7.7±1.3 mg·kg-1) or placebo capsules per day during the course of an 8 wk resistance training protocol. Both groups followed 4-day meat-free meal plans before study commencement, during the 4th week of the protocol, and during the 8th week of the protocol. Skinfold and 10-repetition max test were performed to test body composition and strength, respectively, at each time point. Urine collection (24-hr) was performed to determine urinary 3-methylhistidine (3MH), urinary creatinine (Cr), and the 3MH:creatinine (3MH:Cr). A 2x3 factorial MANOVA with a Bonferroni post-hoc test was used to test significance (p

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: The timing of nutrient ingestion continues to be advocated by athletes, nutritionists, and coaches to augment potential exercise training adaptations. While creatine supplementation is well-established for its ergogenic potential, limited research is available on the potential impact of creatine monohydrate administration before or after workouts among athletes. The aim of this study was to investigate the effects of pre- versus post-exercise creatine monohydrate supplementation on resistance training adaptations, body composition, and work capacity following 8-weeks of supplementation and resistance training. Methods: In a randomized, double-blind, placebo-controlled, parallel design, 34 health resistance-trained male and female athletes were randomly assigned and matched according to fat free mass to consume a placebo, or 5-g dose of creatine monohydrate within 1 hour before training, or within 1 hour after training for 8 weeks while completing a weekly resistance training program. At each time point all participants co-ingested a 25-gram dose whey isolate and a 25-gram dose of carbohydrate powder along with their assigned supplement. A 4-week non-supplementation period of resistance training occurred before the supplementation period to account for any early neuromuscular adaptations associated with starting a new program. Body composition using a 3-compartment field model, muscular strength and muscular endurance using bench press and back squat exercises along with isometric mid-thigh pull were assessed before and after the 8-week supplementation period. A 3 x 2 mixed factorial ANOVA with repeated measures on time were used to determine any statistically significant differences for time and group main effects and group x time interaction effects. Results: Over the training and supplementation period, all groups experienced a significant increase in fat free mass, upper and lower body strength, work capacity, and a decrease in body mass, fat mass, and percent body fat, with no differences observed between groups. Conclusions: Daily supplementation with carbohydrate plus protein with or without creatine monohydrate leads to significant increases in fat-free mass, performance indicators, and work capacity while the ingestion of, or timing creatine monohydrate did not seem to exert any additional influence over the measured outcomes. Retroactively registered on clinicaltrials.gov as NCT05451498.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose was to investigate the effects of progressive resistance training and creatine supplementation in individuals' post-stroke. Participants were randomized to one of two groups: creatine (n = 5; 51 ± 15 yrs, 173.04 ± 10.75 cm, 84.74 ± 19.24 kg) or placebo (n = 3; 73 ± 8 yrs, 171.26 ± 5.31 cm, 73.33 ± 5.83 kg) during 10 weeks of supervised, progressive resistance training. Prior to and following training and supplementation, assessments were made for body composition (lean tissue, fat mass, bone mineral; dual energy x-ray absorptiometry), muscle thickness (elbow and knee flexors and extensors; ultrasound), muscle strength (1-repetition maximum leg-press, chest-press), tasks of functionality (berg balance scale, six-minute walk test), cognition (Montreal Cognitive Assessment), and symptoms of anxiety (Generalized Anxiety Disorder Assessment) and depression (Center for Epidemiological Studies Depression Scale).

This book was released on 2008 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Creatine monohydrate has become one of the most popular ingested nutritional supplements due to its potential enhancement of athletic performance. Creatine absorption from the serum into skeletal muscle occurs through the utilization of a membrane-spanning protein, CreaT1. Numerous creatine formulations have been developed primarily to maximize creatine absorption. Creatine ethyl ester (CEE) has been chemically modified by adding an ester group and is thought to increase creatine bio-availability by by-passing the CreaT1. This study examined how a seven week supplementation regimen with CEE affected body composition, muscle mass and performance, whole body creatine retention, as well physiological and molecular adaptations, associated with creatine uptake in nonresistance-trained males following a resistance-training program. Results demonstrated that CEE did not show any additional benefit to increases in muscle strength/performance or a significant increase in total muscle creatine when compared to creatine monohydrate or placebo. CEE supplementation did show a large increase in creatinine levels throughout the study.

Download or read book The Effects of a Single Dosage of Creatine Hydrochloride on Total Training Volume in Resistance Trained Men Versus Women written by Emily Marie Reuland and published by . This book was released on 2016 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers have reported that creatine monohydrate is an effective ergogenic aid. With a lack of research on women and creatine hydrochloride, there was a need for further research into creatine hydrochloride’s effect on men versus women during resistance training. This study compared the change in total training volume (TTV) from a control trial to an experimental trial between men and women who ingested either a placebo or a single dose of 0.033 grams per kilogram of body weight of creatine hydrochloride. Both sexes in the creatine group and the placebo group significantly increased TTV from the control trial to the experimental trial during the leg press, but there was no significant change in TTV for the bench press. The change in TTV for the leg press compared between the creatine and placebo groups was not significant. There was a significant difference between men and women’s TTV, with women in the creatine group performing more total repetitions than men in the creatine group during the leg press. The efficacy of creatine hydrochloride on resistance training remains unclear.
