Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether a 30 day beef intervention can improve peak cognitive performance in young, normally menstruating adult women. The control group will consume a daily portion of macronutrient equivalent vegetable source of protein.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of the Nutrition, Vision, and Cognition in Health Sport: Beef (IONSport-Beef) study is to conduct a randomized controlled trial to evaluate beef as a nutritional intervention to optimize visual cognitive training performance in generally healthy, normally menstruating women. Female subjects of reproductive age (18-40) will be randomly placed in one of two dietary treatment groups: one serving of beef per day for 30 days or a non-meat protein replacement control. Cognitive performance will be measured in 15 training sessions over 10 days using the sophisticated NeuroTracker™ CORE (NT) 3-Dimensional (3D) software program. It is hypothesized that women consuming 1 serving of beef per day for 30 days will have the highest plasma levels of the beef rich nutrients and demonstrate the highest visual cognitive performance and improvement as compared to the no beef control.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Study participants will be randomized to either one serving of beef or a macronutrient equivalent "veggie patty" per day for 30 days.

Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

note on masking: The title of the study presented to participants is "IONsport: Women and Protein" and the funding source is withheld to mask from participants our underlying hypothesis. It is open label in the sense that they know what they are eating.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

30 day Beef consumption

One serving of beef is consumed each day for 30 days.

Group Type EXPERIMENTAL

30 day Daily consumption of 1 serving of beef

Intervention Type DIETARY_SUPPLEMENT

Beef patty will replace one of the participants protein servings each day for 30 days. Each serving is 114 grams of 90% lean ground sirloin given to participants as an uncooked frozen patty.

30 day Veggie Patty consumption

One serving (1 patty) of a vegetable based protein source is consumed each day for 30 days. The weight of the food, total calories, grams of protein, and total fat are the same as the beef serving.

Group Type PLACEBO_COMPARATOR

30 day Daily consumption of 1 serving of the vegatable protein source

Intervention Type DIETARY_SUPPLEMENT

Veggie patty will replace one of the participants protein servings each day for 30 days. No beef will be consumed during this period. The veggie patty is commercially available Morningstar veggie burger and is given to participants in commercial packaging as a frozen precooked patty.
