THERMOREGULATION AD COOLING STRATEGIES IN ATHLETES WITH A SPINAL CORD INJURY
Athletes with a spinal cord injury SCI
- Inability to thermoregulate effectively
oImpaired sweating and blood flow responses
oLoss of skeletal muscle pump activity
- Thermoregulatory impairment is related to level and completeness of the lesion
- C4 at top; quadriplegia – large proportion of body affected by ability to sweat and
redistribute blood
oAs move down; impairment becomes lessor and lessor
Paralympic sports for those with SCI
- Triathlon, tennis, horse riding, basketball, track
Precooling
- Reducing core body temp before exercise
oDec thermal strain
oImproves performance
- Various methods have been used to able bodied athletes
- Minimal research with Paralympics
Overview: precooling study
- Pre cooling (20 mins) – monitor for 60 mins
- Paraplegic athletes
- Slushies, slushies with cold towels
- Cold water emerging
- Control

Document Summary
Thermoregulation ad cooling strategies in athletes with a spinal cord injury. Inability to thermoregulate effectively: impaired sweating and blood flow responses, loss of skeletal muscle pump activity. Thermoregulatory impairment is related to level and completeness of the lesion. C4 at top; quadriplegia large proportion of body affected by ability to sweat and redistribute blood: as move down; impairment becomes lessor and lessor. Reducing core body temp before exercise: dec thermal strain, improves performance. Various methods have been used to able bodied athletes. Pre cooling (20 mins) monitor for 60 mins. Cold water emersion and slushies and towels may be effective: cold water for lower duration, depending on how soon before exercise it is used. Slushies should be combine with more cooling strategies or a greater volume. Consideration for how the severity of a sci may influence cooling rates is important.
