TI  - Changes in Heart Rate Variability and Executive Functions Following Yoga Practice 
      in Type 2 Diabetes Patients: A Pilot Study.
PG  - 4-10
AB  - CONTEXT: Type 2 diabetes mellitus (T2DM) patients are at increased risk of 
      cognitive impairment and dementia compared to healthy individuals. Lifestyle 
      practices such as yoga can have a vital role in preventing and managing T2DM. 
      Some studies have found that yoga can positively impact cognitive function in 
      T2DM. OBJECTIVE: The study aimed to investigate the benefits of short-term yoga 
      practice on heart rate variability (HRV) and cognitive function for T2DM 
      patients, without a matched control group, to address the paucity of data on the 
      effectiveness of yoga practice on cognitive health on T2DM individuals. DESIGN: 
      Current study is a single group pre post design. SETTING: The study took place in 
      the Department of Yoga and Life Sciences at Swami Vivekananda Yoga Anusandhana 
      Samsthana (S-VYASA) in Bangalore, India. PARTICIPANTS: Participants were 21 T2DM 
      patients from various hospitals, clinics and community setups, in different parts 
      of Bengaluru city in India. INTERVENTION: The participants took part in one month 
      of yoga practice. OUTCOME MEASURES: The research team used the Madrid card 
      sorting test (MCST) to assess participants' executive function (EF) at baseline 
      and postintervention. In addition, the team monitored participants' heart rate 
      variability (HRV) in a resting phase and during task performance. RESULTS: 
      Between baseline and postintervention: (1) participants' reaction time for the 
      MCST decreased for overall task performance (P = .01) and during rule shifting (P 
      = .03); (2) a significant reduction occurred in participants' random errors (REs) 
      and incorrect responses, at P = .02 for both, whereas a significant increase 
      occurred in correct responses and efficient errors (EEs), at P = .03 and P = .01, 
      respectively; (3) the low frequency (LF) and LF/high frequency (HF ) ratio for 
      the HRV decreased; HF increased but the difference wasn't statistically 
      significant; and (4) a statistically significant decrease occurred in LF and 
      LF/HF and an increase in HF occurred during task performance. CONCLUSION: Yoga 
      therapy had beneficial effects on cognitive performance for the T2DM 
      participants. The yoga practice also positively affected autonomic functions 
      during task performance and suggesting that it can reduce task-induced stress. 
      It's important for the future studies to validate the current findings with a 
      randomized controlled trial.
