Simple Explanation

Spinal cord injuries disrupt the body's ability to regulate temperature, especially in athletes. This study looked at whether spraying water on the skin could help athletes with spinal cord injuries stay cool during exercise. The study compared the effect of water spray on core temperature during exercise in athletes with tetraplegia, paraplegia, and able-bodied individuals. The results showed that water spray helped to keep core temperature down in athletes with tetraplegia, suggesting it can be a useful cooling technique.

Study Duration
Not specified
Participants
11 individuals with SCI (7 tetraplegia, 4 paraplegia) and 16 able-bodied controls
Evidence Level
Interventional crossover study

Key Findings

  • 1
    Water spray significantly attenuated the rise in core temperature in athletes with tetraplegia during exercise.
  • 2
    The change in core temperature was significantly higher in the tetraplegia group compared to paraplegia and able-bodied groups under control conditions.
  • 3
    Water spray did not significantly change the change in core temperature in athletes with paraplegia or able-bodied individuals.

Research Summary

This study evaluated the effect of water spray (WS) on core temperature (Tc) during exercise in athletes with spinal cord injury (SCI) compared to able-bodied (AB) individuals. The key finding was that WS effectively attenuated Tc elevation during exercise in athletes with tetraplegia (TP), allowing them to dissipate heat as efficiently as AB individuals. WS had no significant impact on Tc in persons with paraplegia (PP), but interestingly, provided additional heat dissipation to AB persons only after 60 minutes of exercise.

Practical Implications

Practical Cooling Strategy

Water spray is a practical and effective cooling strategy for athletes with tetraplegia during exercise.

Targeted Application

Water spray should be applied to a minimum of 40% of total body surface area, including the forehead, chest, and back, for optimal cooling.

Competition Use

The findings support the use of water spray by paralympic athletes with tetraplegia during competitions to manage core temperature.

Study Limitations

  • 1
    Small and unequal sample sizes
  • 2
    Data collection on the same day for able-bodied group only
  • 3
    Different sports played between groups
