exercise than to endurance exercise.

BACKGROUND: Heat sensitivity (HS) is reported by 58% of all persons with multiple
sclerosis (MS), causing symptom exacerbation possibly limiting exercise
participation.
OBJECTIVE: The purpose of this study was to test the hypotheses
that (a) a relationship between exercise-induced changes in core-temperature
(C(temp)) and changes in symptom intensity exists, and (b) that resistance
exercise (RE), as a consequence of a minor increase in core temperature, will
induce a lesser worsening of symptoms than endurance exercise (EE) in HS persons
with MS.
METHODS: On two separate days, 16 HS persons with MS randomly completed
a session of RE and EE, or EE and RE, respectively. Testing was conducted pre,
post and one hour after exercise and consisted of Visual Analogue Scale (VAS)
scoring (fatigue, spasticity, pain, strength, walking and balance), the 5-time
sit-to-stand (5STS), the Multiple Sclerosis Functional Composite (MSFC) and Body
Sway. Composite scores describing average subjective symptom intensity (SI) and
total number of symptoms (SN) were calculated from VAS scores.
RESULTS: C(temp)
(0.9±0.4°C vs 0.3±0.1°C, p<0.001), SI (1.7±1.9 cm vs 0.6±1.5 cm, p<0.05) and SN
(1.6±1.9 vs 0.6±2.1, p<0.05) increased significantly more during EE than RE.
Changes in C(temp) correlated to changes in SI (r=0.50, p<0.01). No differences
were observed in 5STS, MSFC and Body Sway scores after EE when compared to RE.
CONCLUSION: An exercise-induced increase in C(temp) is associated with increased
number and severity of perceived symptoms in HS persons with MS. Based on these
findings it is expected that HS persons with MS do tolerate RE better than EE.
