Can anti-gravity running improve performance to the same degree as over-ground running?

Area of Science:

• Sports Science
• Exercise Physiology
• Biomechanics

Background:

• Athletes often use various training methods to enhance running performance.
• Anti-gravity (AG) treadmills offer a low-impact alternative for training.
• The long-term effects of AG running on performance and physiological markers require further investigation.

Purpose of the Study:

• To compare the effects of 8-week anti-gravity (AG) running versus over-ground (OG) running on running performance, maximal blood lactate, and running kinematics in elite cricketers.

Main Methods:

• Fifteen elite male cricketers were divided into an AG group (training on AG treadmill and OG) and a CON group (OG training only).
• Both groups trained for 8 weeks, with performance metrics, blood lactate concentrations, and running kinematics assessed.

Main Results:

• Both AG and OG training improved time trial and shuttle run performance similarly.
• OG training led to greater improvements in maximal running performance and maximal blood lactate concentrations compared to AG training.
• AG training resulted in moderate increases in stride length and decreases in stride rate, indicating altered running mechanics.

Conclusions:

• While AG running can supplement OG training, its prolonged use may negatively impact stride mechanics and blood lactate response.
• Athletes and coaches should cautiously integrate AG training into performance programs.
• OG running appears more effective for enhancing maximal running capacity and lactate accumulation in this population.
