Cycle Ergometer Hardware Evaluation (DTO 651)
Principal Investigator
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
The Shuttle Treadmill is the only certified in-flight exercise hardware that is flown on missions of varying durations. Treadmill use has raised several concerns including noise, vibration, subject discomfort, and the inability to quantify workload. These concerns warrant evaluation of alternate in-flight exercise hardware.

The objectives of this study were 1) to evaluate the cycle ergometer for ease of set up and stowage, physical comfort, and subject restraint affectivity on different crewmembers' performance; 2) to quantify the magnitude and frequency spectrum of vibration during cycle ergometer exercise sessions; and 3) to compare crewmember responses to cycle ergometer workloads using a heartwatch.
