Energy Availability in Male and Female Elite Wheelchair Athletes Over Seven Consecutive Training Days

Completed

• Conditions: Energy Supply; Deficiency
• Interventions: Other: evaluating energy availability

• Registration Number: NCT04254900
• Lead Sponsor: Swiss Paraplegic Research, Nottwil

Brief Summary

Low energy availability (LEA) is a major problem in sports as athletes ingest often a lower amount of energy compared to their actual needs. The availability of energy is calculated based on their daily energy intake and the energy cost of the daily training sessions in relation to their fat-free mass. Based on this calculation, it is known how much energy will available for the body (beside the fuel for training) to keep it in optimal physiological functioning. It has been shown, that LEA occurs very often in female athletes, in endurance athletes as well as athletes in weight-sensitive sports (i.e. jockeys, combat sports, gymnastics, ballet). The purpose of this study was to investigate, whether LEA is a problem in wheelchair athletes as well.

Detailed Description

Energy availability will be assessed over 7 consecutive training days using a dietary and training record as well as the Leisure Time PHysical Activity Questionnaire for spinal cord injury. Resting Energy expenditure will be measured as well as body composition (by a DXA) before the start of data collection.

Primary Outcome Measures

Name	Time	Method
energy availability	7 consecutive days during pre-season	energy availability = (energy intake - exercise energy expenditure) / fat-free mass. Energy intake and exercise energy expenditure are measured using a food and training diary. The fat-free mass will be measured using a DXA scan.
