Macronutrient Supplementation For Endurance Athletes, Jonathan B. Hurst

Senior Honors Projects, 2010-2019

Purpose: The present study addressed two questions related to macronutrient supplementation during endurance exercise. Firstly, the effects of carbohydrate and protein co-ingestion on time trial (TT) performance were compared to carbohydrate alone. Secondly, the effects of isolated protein ingestion on TT performance were compared to a placebo.

Methods: Six trained cyclists (Age: 22 ± 1 years; Height: 167 ± 12 cm; Weight: 60 ± 10 kg; VO_2max: 62 ± 7 ml/kg/min) completed four experimental trials, consisting of constant-load cycling for two hours (55% W_max) immediately followed by a 30-km simulated time trial. During the trials, subjects …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The main aim of this study was to determine if IPC after a 5000 m run influences maximal effort 1600 m run performance. A secondary purpose was to determine if the level of IPC pressure used influences run performance. Nine subjects (6 male and 3 female were included in the study; 30 years±5.19 years; Height 173.72cm±8.25; Weight; 72.54±9.97 kg). These subjects were recruited to be in this study via word of mouth or social media advertisement in the Las Vegas area. Participant inclusion criteria was 18- 50 year old apparently healthy, had been running a minimum of 20 miles a …

Effect Of Retinol And Retinol Esters On Performance, Egg Quality, And Blood And Egg Vitamin A Levels In Laying Quails, Murat İlhan, Tuba Bülbül

Turkish Journal of Veterinary & Animal Sciences

This study aimed to determine the effects of retinol and retinol ester supplementation on performance, egg quality, serum and egg oxidative status, and vitamin A levels in laying quails. Three hundred quails were divided into 5 groups. The control group received a basal diet that contained vitamin premix without vitamin A or vitamin A precursors. The treatment groups received dietary supplementation with retinol and retinol esters [retinyl acetate (R-acetate), retinyl palmitate (R-palmitate), retinyl propionate (R-propionate), 3300 IU/kg]. Egg production and feed conversion ratio improved in all experimental groups. Serum β-carotene and malondialdehyde (MDA) levels decreased and serum retinol levels increased …

Effects Of Dietary Chicken Grill And Sunflower Seed Oils On Performance, Egg Yolk Cholesterol Level, Biochemical Parameters, And Oxidant/Antioxidant Status Of Laying Hens, Mustafa Numan Oğuz, Fatma Karakaş Oğuz, Tülay Büyükoğlu

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to investigate the effects of dietary chicken grill oil (CGO) and sunflower seed oil (SO) on performance, some serum and egg yolk biochemical parameters, and blood and liver oxidant/antioxidant status of laying hens. Fifty-four 19-week-old Lohmann laying hens were randomly assigned to three groups. The groups were fed experimental diets containing 5% SO, 5% CGO1, or 7.5% CGO2, respectively. Diets and water were provided ad libitum over 17 weeks. The feed efficiency ratios and cholesterol content in egg yolks with cholesterol and the triglyceride levels in serum were not affected by the diets. However, …

Development And Evaluation Of A Firefighter Physical Performance Program For Undergraduate Fire And Safety Students, Jessica Ann Moody

Online Theses and Dissertations

The number one on-duty cause of death in the fire service is heart attacks. The International Association of Firefighters and the International Association of Fire Chiefs teamed up to create the Candidate Physical Ability Test (CPAT). Fire departments across the nation will have consistent physical performance tests to hire more physically capable candidates as part of the Wellness-Fitness Initiative (International Association of Fire Fighters, 2014).

Eastern Kentucky University is a nationally recognized school for its fire science program; however students are not required to take educational classes to better prepare them for physical performance tests. Students starting in a training …

In Ovo Feeding With Ss-Hydroxy Ss-Methylbutyrate And Broilerperformance, Intestinal Health, And Immunity Status, Ömer Hakan Muğlali, Mustafa Salman, Ayhan Gacar, Fi̇li̇z Akdağ, Mustafa Yavuz Gülbahar, Alper Çi̇ftçi̇, Ertan Emek Onuk, Fi̇li̇z Karadaş, Hüseyi̇n Eseceli̇

Turkish Journal of Veterinary & Animal Sciences

The effects of in ovo administration of β-hydroxy-β-methylbutyrate (HMB) on broiler performance, intestinal health, and immunity were investigated. At day 18 of incubation, fertile eggs were divided into negative (no injection) and positive (physiologic serum injection) controls and three HMB treatment groups. HMB solution was injected at 0.1% (Group 1), 0.2% (Group 2), and 0.3% (Group 3) concentrations. There were no significant differences between the groups for live weight gain, feed conversion rate, and hot carcass, breast meat, liver, and heart weight. However, the gizzard weight in Group 1 was significantly higher than those in the other groups (P < 0.05). Although the intestinal villi lengths in the treatment Groups 1 and 3 on day 20 were greater than those in the control groups (P < 0.01), at the end of the experiment there were no significant differences among the groups. For antibody levels, the differences between groups on days 4 and 42 were highly significant (P < 0.01), and the antibody levels in Group 2 were higher than those in the other groups. Separately, growth performance and antibody levels were positively correlated with the length of villi in Group 2 (HMB 0.2%).

Appraisal Of The Impact Of Aluminosilicate Use On The Health And Performance Of Poultry, Ali Gilani, Hassan Kermanshahi, Abolghasem Golian, Saeed Seifi

Turkish Journal of Veterinary & Animal Sciences

Aluminosilicates are feed additives used for multiple purposes in the poultry industry. Bentonites, zeolites, and kaolins are types of aluminosilicate compounds that appear in the marketplace due to their capabilities as mycotoxin adsorbents and other qualifications. While there are some differences among their efficacies, anecdotal evidence confirms that these additives ameliorate aflatoxicosis and manure ammonia emission, and improve the durability of pelleted diets. Furthermore, these supplements are safe at 0.2%-1% inclusion levels in the commercial diet of broilers and layers and did not have any adverse effects on productive indices, and even promoted birds' performance. Nevertheless, their upper levels, especially …

Effects Of Combining Recombinant Bovine Growth Hormone And Anabolic Implants On Growth Performance And Dietary Energetics Of Holstein Bull Calves Fed Finishing Diets, Victor Gonzalez-Vizcarra, Maria Lopez-Soto, Carolina Pujol-Manriquez, Jesus Urias-Estrada, Alberto Barreras Serrano, Jose Calderon-Cortes, Gilberto Lopez-Valencia, Francisco Monge-Navarro, Alejandro Plascencia

Turkish Journal of Veterinary & Animal Sciences

Twenty-one Holstein bull calves (368 ± 5.2 kg) were used in order to evaluate the effects of combining recombinant bovine growth hormone (bST) and anabolic implants on growth performance and dietary energetics. Steers were assigned (7 repetitions/treatment) to individual pens (16 m2) equipped with automatic waterers and 1.2 m fence-line feed bunks. The experiment lasted 56 days. Treatments were: 1) no bST, no implant; 2) implant; and 3) bST + implant. Compared to implanted cattle, the combination of exogenous bovine somatotropin and anabolic implants did not enhance growth performance or observed dietary energy. Compared to nonimplanted cattle, anabolic implants increased …
