Peripheral neuropathy is a common complaint of diabetes which could in turn cause balance impairments. Further, hypohydration is known to degrade orthostatic tolerance via reduced blood volume (hypovolemia) which alters baroreceptor responsiveness, and perhaps reducing brain blood flow. However, no data exist on the effect of hypohydration on dynamic balance in people with type II diabetes. PURPOSE: The purpose of this investigation was to examine the effects of hypohydration on dynamic balance in patients with type II diabetes. METHODS: 10 type II males with diabetes (age: 52±8 y, weight: 94.8±22.2 kg, HbA1c: 6.9±1.0%, BMI: 33.1±10.8 kg/m 2 ; body fat: 31.7±6.1%) performed two trials on dynamic postural balance while either euhydrated (urine specific gravity, USG<1.020) or hypohydrated (USG蠅1.020; ‐1% body mass). Euhydration was achieved by standard water prescription in line with the dietary reference intakes for water, and hypohydration was achieved through progressive water restriction over three days leading up to the test. Balance was assessed using a Biodex Balance System examining overall stability index (OSI), medial‐lateral stability index (MLSI), and anterior‐posterior stability index (APSI). RESULTS: USG was lower in euhydrated trial (1.011±0.006) compared to the hypohydrated trial of (1.028±0.006; p<0.05). There was no difference in OSI between euhydrated and hypohydrated trials (3.4±1.8 vs. 3.7±2.4 s; p>0.05). Similarly, there were no differences in MLSI (1.9±1.1 vs. 2.3±1.6) or APSI (2.4±1.2 vs. 2.4±1.5; p>0.05). CONCLUSION The results indicated that mild hypohydration by water restriction does not significantly alter dynamic balance in type II diabetics.
