Description
OBJECTIVES:
A comprehensive understanding of the kinematics and kinetics of resistance exercise performance in microgravity is necessary to optimize exercise prescription by including the exercise variations that have the greatest potential health benefits. However, to date, there have been no biomechanical investigations of resistance exercise performance on the International Space Station (ISS), and none of Advanced Resistive Exercise Device (ARED) exercise in microgravity. Collecting biomechanical data during actual exercise sessions on the ISS is expensive and complex, but is required for program optimization. The investigators proposed this initial ground-based evaluation that would increase the probability of success for a future experiment to be performed on the ISS. The purpose of this investigation was to quantify the joint loading that occurs during typical resistance exercise on the ARED. The goal is to determine a subset of exercises that show the greatest potential for maximizing health benefits to inform a future proposal that will include a biomechanical analysis of exercise on the ISS.

Specific Aim 1: To quantify the joint loading that occurs during resistance exercise using the ARED.
The goal of this aim was to determine joint kinematics, torque, power, and work during typical resistance exercise on the ARED. The objective was to identify the exercises that will optimize exercise effectiveness for bone and muscle health, and to determine if kinetic responses depend upon exercise type.

Specific Aim 2.: To create a list of exercises that will be used during a future in-flight analysis of resistance exercise on the ARED.
The goal of this aim was to determine which form variations of the squat and deadlift exercise would be most beneficial to study during an in-flight study of resistance exercise. The objective was to determine the exercises that either maximize joint loading or are sufficiently different from other form variations to be considered unique.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.

The Human Research Roadmap is located at: https://humanresearchroadmap.nasa.gov/
