Impact of Nutrition Education and Whey Supplementation on Body Composition and Endurance Performance of Athletes
- Conditions
- Healthy
- Registration Number
- NCT06682715
- Lead Sponsor
- University of Veterinary and Animal Sciences, Lahore - Pakistan
- Brief Summary
Objectives of study are:
* Examining the influence of nutrition education/counseling on overall dietary protein consumption.
* Change in body composition parameters (body mass in kg, BMI kg/m2, fat mass(kg), fat free mass(kg), skeletal muscle mass(kg), percent body fat ) measured by InBody-270 analyzer over 5 weeks.
* Change in maximal oxygen consumption assessed using the Rockport Fitness Test after 5 weeks of supplementation.
20 participants will be randomly assigned to whey or placebo (maltodextrin) group. Pre and post-analysis will be done for body composition, nutrition knowledge and dietary assessment and maximal oxygen consumption. Along with supplementation during week 2-6, individualized nutrition education with food logging will be provided with their programmed training. Changes in body composition (body mass in kg, BMI kg/m2, fat mass(kg), fat free mass(kg), skeletal muscle mass(kg), percent body fat) using In Body Composition Analyzer, maximal oxygen consumption using Rockport Fitness test (1 mile test), protein intake and nutrition knowledge using Nutrition for Sports Knowledge Questionnaire will be assessed.
- Detailed Description
Proposed place of work:
I. Football team players from public universities in Lahore.
Plan of work and methodology adopted:
* Study design: Experimental
* Duration of study: 7 weeks
* Participants recruitment: 20 male football players, aged between 18-30 years.
Intervention plan:
Groups Dose Duration Treatment group(n=15) 24g whey protein 5 weeks Placebo group(n=15) Isocaloric maltodextrin 5 weeks
Subjects:
Participants (n=20) will be recruited after initial consent in which they will be fully informed about all benefits, risks, and discomforts of this investigation. Screening process will include Minimum Age: 18 Years Maximum Age: 30 Years
Inclusion Criteria:
Age range: 18-30 years BMI: 18.5 kg/m² to 30 kg/m² Participation in ≥5 training sessions per week
Exclusion Criteria:
Known allergies to whey Recent history of illnesses, musculoskeletal issues, or metabolic diseases use supplementation/medication
Research layout plan:
A randomized study design will be used to compare the effects of whey vs maltodextrin (placebo) on university football players. The study will be performed during the time period of 7 weeks.
Pre and post testing:
In the 1st and 7th week, each participant will have their body composition analysed using InBody-270, USA. Parameters of interest in BIA are fat-mass, fat-free mass, BMI. Nutrition knowledge will be assessed using modified The Nutrition for Sports Knowledge Questionnaire and endurance performance will be assessed using Rockport fitness test (1mile test) for maximal oxygen consumption calculation.
Dietary assessment:
3 day food dietary recall will be used initially in the 1st week to assess their dietary protein intake. Based on a dietary analysis, participants will be given a dietary plan (taking into account the resting metabolic rate and total daily physical activity related energy expenditure) and their daily protein needs will be calculated using 1.4g/kg of body weight for each participant.
Nutrition education and supplementation:
Nutrition education will be given using evidence based nutrition education hand-outs and one-on-one counselling for each athlete in which they will be guided about sources of high biological value protein sources to meet daily protein requirement. Dietary intake will be monitored using 3 day food record method during 2-6 weeks of supplementation. Food logs will be filled out by participants during each week to monitor their protein intake. Three food logs (2 weekdays \[Mon-Thurs/Tue-Fri\] and 1 weekend day \[Sat/Sun\]) will be submitted by each subject every week.
Supplemental drinks will include 24g whey protein or iso-caloric amount of maltodextrin for placebo. Participants will be directed to perform their regular training sessions 5-6times/ week.
Performance test:
A valid field test to determine maximal oxygen consumption in the public is the Rockport Walk Fitness test. Furthermore, it requires little preparation and can be delivered to big crowds. Participants will be given instructions to abstain from strenuous exercise beginning 24 hours before to Rockport walk/run fitness test. On the day of the exam, they will be instructed to eat a light breakfast and report to the gym for recording after two hours. On the treadmill, participants will be told to walk as quickly as they can for 1 mile. The stopwatch will be used to time how long it takes to finish the test. The heart rate will be assessed pre and post 1 mile walk. Maximal oxygen consumption will be calculated by using equation.
