About this trial
The goal is to improve nutrition screening and support for Division III athletes.
The study will use standard, low-risk nutrition screening methods, such as measuring height, weight, grip strength, and body composition, as well as having athletes complete questionnaires. Dietitians trained in sports nutrition will provide nutrition advice based on these screenings.
Data will be collected at three points during the season: before the season starts, mid-season, and after the season ends. This study builds on earlier research conducted at Case Western Reserve University that showed nutrition support can improve athletes' health and performance.

Trial outcomes
Primary outcomes
1
Grip Strength
Grip force in kilograms determined by a handgrip dynamometer, conducted on both arms, according to standard practice procedures.
Time frame
Baseline/Pre-season (August 2025), Mid-season (~2 months after baseline; October 2025), End of Study/End of Competitive Season (~4 months after baseline; December 2025)Secondary outcomes
1
Low Energy Availability in Females Questionnaire (LEAF -Q)
Female participants only. Focuses on physiological symptoms of insufficient energy intake. includes 25 questions arranged in three separate, sequential sections: injuries, gastrointestinal, and reproductive functions. (score; 0-36; total score ≥8 is to be considered at risk)
Time frame
Baseline/Pre-season (August 2025), Mid-season (~2 months after baseline; October 2025), End of Study/End of Competitive Season (~4 months after baseline; December 2025)2
Low Energy Availability in Males Questionnaire (LEAM -Q)
The low energy availability in males questionnaire (LEAM -Q), focuses on physiological symptoms of relative energy deficiency. Categories include dizziness, gastrointestinal function, thermoregulation at rest, health problems, and recovery. The questionnaire also focuses on physiological symptoms of relative energy deficiency. A higher total score indicates a greater risk of low energy availability. Precise scoring cutoffs are not yet defined.
