Project Abstract

Abstract

Proper nutrition is a critical yet often overlooked component of optimizing athletic performance and recovery. While college athletes expend considerable energy through demanding training and competition schedules, many exhibit suboptimal dietary habits that can undermine their physical development, energy levels, injury risk, and overall performance capacity. Limited nutritional knowledge among athletes has been identified as a key contributor to poor dietary choices and challenges adhering to sports nutrition guidelines. This study aims to comprehensively assess nutritional knowledge and dietary patterns among college athletes across a range of varsity sports. Through validated surveys and analyses of multi-day dietary intake logs, the primary objectives are to 1) Evaluate athletes' knowledge of core sports nutrition concepts, 2) Characterize macro and micronutrient intake quantities and quality, 3) Identify common dietary deficiencies and unhealthy eating patterns, and 4) Explore demographic and sport-specific differences in knowledge and habits. Further, qualitative interviews will probe perceived barriers, environmental influences, nutrition education experiences, and dietary strategies around training and competition. By establishing an evidence-based understanding of the current landscape, findings from this research can inform strategies to enhance nutrition literacy and facilitate adoption of optimal dietary practices among collegiate athletes. Specific recommendations may include curriculum development for sports nutrition education programs, improving access to dietary support resources, and informing institutional policies related to meal provision and supplement regulations. Ultimately, enabling college athletes to apply evidence-based sports nutrition knowledge can unlock peak performance outcomes and positive long-term dietary habits.

Project Overview

Chapter 1: Introduction

1.1 Background and Significance The nutritional demands faced by college athletes engaged in intensive training and competition are immense. In addition to meeting basic caloric needs, athletes require specific macro and micronutrient intake patterns to optimize muscle growth and recovery, maintain healthy body composition, support immune function, prevent injury/illness, and sustain peak physical and cognitive performance (Desbrow et al., 2014). However, accumulating evidence indicates that the diets of many college athletes across sports are inadequate and inconsistent with evidence-based sports nutrition guidelines (Shriver et al., 2013). Suboptimal nutritional intake can directly impair training capacity and performance while increasing risks of injury, fatigue, illness, poor recovery, and undesirable body composition changes (Lun et al., 2009). Beyond short-term impacts, poor dietary habits and lack of nutrition knowledge established during the college years often continue later in athletes' careers and lives.

One key factor identified as a barrier to achieving recommended nutrient intake and fueling strategies is athletes' limited knowledge of proper sports nutrition principles (Jacobson & Aldana, 2001). Many college athletes report receiving inadequate education and guidance related to optimal diets, hydration, supplementation, meal timing, and other dietary strategies that can maximize performance and recovery (Edericks & Morse, 2005). Greater nutrition literacy has been linked to more favorable dietary practices across athletes. As nutrition plays such an integral role in optimizing athletic development and output, establishing a clear understanding of college athletes' current nutrition knowledge deficits and dietary habits represents an important area of inquiry.

1.2 Problem Statement Despite extensive scientific evidence highlighting how specific nutritional strategies and intake patterns can profoundly influence athletic performance, achieving peak conditioning, supporting recovery, regulating body composition, and preventing injuries and illness, many college athletes struggle to implement recommended dietary practices. This gap between evidence-based sports nutrition and typical collegiate athlete dietary behaviors appears driven by suboptimal knowledge of proper fueling strategies across the cohort. However, existing research assessing college athletes' sports nutrition knowledge and dietary habits has yielded somewhat mixed results, with findings potentially confounded by limitations around specific sports assessed, survey tools utilized, dietary analysis methodology, and examination of key demographic and contextual factors like gender, sport type, training volume, and institutional resources that may moderate knowledge and behaviors (Alaunyte et al., 2022). A comprehensive, multidimensional evaluation of nutritional knowledge and intake patterns among college athletes is needed to identify specific gaps and inform targeted nutrition education and behavior change initiatives.

1.3 Purpose of the Study The primary aims of this mixed-methods study are to:

1. Assess college athletes' knowledge of core sports nutrition principles through validated survey instruments.
2. Characterize macro and micronutrient intake quantities, sources, and overall dietary quality patterns through multi-day dietary logs and analysis software.
3. Identify common nutritional deficiencies, suboptimal eating patterns or habits, and barriers to adherence to sports nutrition guidelines.
4. Explore how nutritional knowledge, dietary patterns, and attitudes toward sports nutrition vary across key demographic factors like gender, sport type, training volume, and institutional variables.
5. Through qualitative interviews, gain deeper insight into athletes' experiences, perceived challenges, available resources and specific needs surrounding sports nutrition education and adherence.

Establishing a comprehensive understanding of these factors can guide development of targeted educational interventions, policies, and supportive resources to address knowledge gaps and facilitate optimal dietary behaviors for sustaining peak performance and athletic development.

1.4 Research Questions The following research questions will guide this investigation:

1. What is the current level of sports nutrition knowledge among college athletes, and how does this vary across demographic and athletic factors?
2. To what extent do college athletes' diets align with evidence-based sports nutrition guidelines in terms of macronutrient, micronutrient, hydration, and overall dietary quality? What are the most common deficiencies or problematic patterns?
3. What individual, social, environmental, and institutional factors influence college athletes' dietary habits and ability to adhere to sports nutrition principles?
4. What specific education, resources, interventions, or policy considerations do athletes perceive as most valuable for developing sports nutrition literacy and facilitating optimal dietary behaviors?

1.5 Significance of the Study
The findings and recommendations derived from this comprehensive assessment can significantly impact multiple stakeholders:

For college athletes, a clearer understanding of common nutritional gaps can guide targeted education and resources, empowering them to implement evidence-based dietary strategies that optimize training, recovery, injury prevention and peak performance outcomes. Nutrition habits established during college can also foster lifelong healthy practices.

For athletic departments, sports nutrition staff, coaches, and trainers, insights into athletes' needs and barriers can shape team nutrition programming, educational curriculum, dietary support resources, and relevant policies to ensure athletes at all levels receive necessary nutritional guidance.

Within higher education, the study can inform appropriate institutional-level nutrition services, food provision models, facility designs, and wellness policies that create environments conducive to athletes achieving optimal dietary intake with convenience.

For sport nutrition educators and researchers, the investigation can yield opportunities to develop and validate improved educational interventions and assessment tools while identifying important psychosocial factors and determinants of dietary behaviors among athletes.

Overall, establishing empirically-grounded understanding of this issue is a vital step towards systemically optimizing nutritional habits and ultimately unlocking the full performance potential of collegiate athletes.
