A WORKLOAD SELECTION PROCEDURE FOR THE ÅSTRAND-RYHMING TEST FOR WOMEN

Area of Science:

• Exercise Physiology
• Cardiorespiratory Fitness Assessment

Background:

• The Åstrand-Ryhming Submaximal Bicycle Test is a standard method for estimating maximal oxygen consumption (VO2 max).
• A key challenge in administering this test is selecting an appropriate workload to achieve target heart rates.
• Previous protocols have focused on male participants, potentially limiting accuracy for female populations.

Purpose of the Study:

• To develop and validate a specific workload selection procedure for the Åstrand-Ryhming test tailored to female participants.
• To improve the accuracy of maximal oxygen consumption estimation in women by optimizing the test protocol.

Main Methods:

• A new workload selection procedure was designed for female participants.
• The effectiveness of this new procedure was compared against the original Åstrand-Ryhming protocol.
• The primary outcome measure was the average heart rate during the final two minutes (minutes five and six) of the test.

Main Results:

• The newly developed workload selection procedure for women resulted in a final average heart rate closer to the target range of 165-170 bpm.
• This contrasts with the original Åstrand-Ryhming procedure, which was less effective in eliciting the desired heart rate response in female participants.
• The findings suggest improved protocol adherence and potentially more accurate VO2 max estimations.

Conclusions:

• The proposed workload selection method offers a more effective approach for female participants undergoing the Åstrand-Ryhming Submaximal Bicycle Test.
• This optimized protocol enhances the reliability and accuracy of estimating maximal oxygen consumption in women.
• Further research may explore broader applications and validation across diverse female demographics.
