Brief Summary

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

In a population of boys and girls high school basketball players, the primary objectives are to assess 1) bone mineral density and vitamin D status, and 2) energy intake and dietary quality.

The secondary objectives are to assess 1) nutrients related to bone health (calcium, magnesium, vitamin K, protein) and 2) protein intake over the day.

Data collection takes place pre-, mid-, and post-season.

Detailed Description

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

This study will assess the dietary intake male and female 14-19 year old student athletes, specifically energy intake and dietary quality (i.e. how closely do their diets meet recommendations).

Investigators hypothesize that vitamin D status will be suboptimal in most participants though bone density will be normal.

Investigators hypothesize that participants will maintain energy balance over the course of the season (no significant changes to body mass or body composition) but dietary quality will not meet recommendations.
