Physiological and Dietary Characteristics of Boys and Girls High School Basketball Players

PepsiCo Global R&D120 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

Bone mineral density

whole body

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Normal whole body bone density would be better.

Bone mineral density

spine

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Normal spine bone density would be better.

Bone mineral density

total hip

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Normal total hip bone density would be better.

Bone mineral density

femoral neck

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Normal femoral neck bone density would be better.

Bone mineral density

vitamin D status

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Adequacy will be defined as a value > 32 ng/mL. Higher Vitamin D values would be better.

Energy intake

24 hour recall

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Energy intake that meets recommendations would be better.

Dietary quality

24 hour recall

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Diet quality that meets recommendations would be better.

Secondary Outcomes

Assess nutrients related to bone health (calcium)

Calcium intake via 24 hour recall and calcium supplement, if any

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Calcium intake that meets recommendations would be better.

Assess nutrients related to bone health (magnesium)

Magnesium intake via 24 hour recall and magnesium supplement, if any

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Magnesium intake that meets recommendations would be better.

Assess nutrients related to bone health (vitamin K)

Vitamin K intake via 24 hour recall and vitamin K supplement, if any

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Vitamin K intake that meets recommendations would be better.

Assess nutrients related to bone health (protein)

Protein intake via 24 hour recall

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Protein intake that meets recommendations would be better.

Protein intake over the day

Times of day protein is consumed

Time frame: Changes from basketball pre-season (October 2022) to mid-season (January 2023) to post-season (April 2023). Looking at pattern of protein intake.
