An Investigation of the Sled-Push Exercise Using a Resisted Sled Machine in Apparently Healthy Older Adults: An...

Area of Science:

• Gerontology
• Exercise Physiology
• Sports Science

Background:

• Physical function is crucial for healthy aging.
• Exercise is a key factor in maintaining physical function in older adults.
• Novel exercise modalities are needed to promote cardiovascular health in this population.

Purpose of the Study:

• To assess the feasibility and physiological/psychological responses to an acute progressive sled-push (SLP) exercise session using the XPO Sled Trainer in older adults.
• To compare these responses with a walking (WKC) condition.
• To evaluate the safety and potential benefits of SLP exercise for older adults.

Main Methods:

• Thirty-six older adults were randomized into SLP or WKC groups.
• The SLP protocol involved six bouts of progressive intensity exercise with rest periods.
• Physiological (heart rate, blood pressure, lactate, RPE) and psychological (enjoyment) measures were collected.

Main Results:

• No adverse events occurred; all participants completed the protocol.
• SLP exercise elicited significantly higher physiological responses compared to WKC as intensity increased.
• Enjoyment declined with increasing intensity during SLP but was similar to WKC overall.

Conclusions:

• Progressive sled-push exercise using the XPO Sled Trainer is safe and feasible for older adults.
• SLP is an intensity-driven exercise modality with potential for positive cardiovascular adaptations.
• This exercise offers acceptable enjoyment levels for older adults, supporting its use in healthy aging interventions.
