Effect of Yoga and Walking on Glycemic Control for the Management of Type 2 Diabetes: A Systematic Review and Meta-analysis.

Background: A daily habit of yogic practice or walking, along with an oral hypoglycemic agent (OHA) could be beneficial for better control of type 2 diabetes mellitus (T2DM). We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to find out the efficiency of yoga or walking on glycemic control in T2DM. Methodology: The present systematic review and meta-analysis were completed according to the PRISMA guidelines. The risk of bias in included studies was evaluated, by using the revised Cochrane risk-of-bias tool for randomized trials. Meta-analysis was implemented using RevMan software. Forest plots were used to illustrate the study findings and meta-analysis results. Results: Sixteen studies were included in this systematic review, where 1820 participants were allocated to one of the following interventions: yoga, walking, and without any regular exercise (control group). Participants were between 17-75 years of age. Compared to the control group, the yoga group had a significant reduction in fasting blood glucose (FBG) by 31.98 mg/dL (95% CI = -47.93 to -16.03), postprandial blood glucose (PPBG) by 25.59 mg/dL (95% CI = -44.00 to -7.18], glycosylated hemoglobin (HbAlc) by 0.73% (95% CI = -1.24 to -0.22), fasting insulin by 7.19 µIU/mL (95% CI = -12.10 to -2.28), and homeostatic model assessment for insulin resistance (HOMA-IR) by 3.87 (95% CI = -8.40 to -0.66). Compared to the control group, the walking group had a significant reduction in FBG by 12.37 mg/dL (95% CI = -20.06 to -4.68) and HbA1c by 0.35% (95% CI = -0.70 to -0.01). Compared to the walking group, the yoga group had a significant reduction in FBG by 12.07 mg/dL (95% CI = -24.34 to - 0.20), HbA1c by 0.20% (95% CI = -0.37 to -0.04), fasting insulin by 10.06 µIU/mL (95% CI = -23.84 to 3.71) and HOMA-IR by 5.97 (95% CI = -16.92 to 4.99). Conclusions: Yoga or walking with OHA has positive effects on glycemic control. For the management of T2DM, yoga has relatively more significant effects on glycemic control than walking.Review registration number: PROSPERO registration number CRD42022310213.

Effect of Karate on Neurocognitive Physiology: A Focused Review.

Background: The literature survey shows improvement in cognitive performance following acute bouts of physical exercise and chronic exercise patterns. However, neurocognitive growth through karate, a moderate intensity physical activity, is very limited. The synchronization of the nervous and endocrine system can be best reflected through this martial art form through neurogenesis and cognitive potentiation. Numerous outstanding reviews have summarized these findings for martial arts like judo and taekwondo. This review tries to orchestrate the efficiency of karate in neurocognition. Objective of the Study: The specific aim of this review paper is to magnify the efficiency of karate training in cognitive functions, through its response to neurochemical transmissions and electrophysiological signaling. Materials and Method: Numerous related literature were evaluated, screened, and selected using the Preferred Reporting Items for Systematic reviews and Meta-Analyses eligibility criteria. All appropriate publications that satisfied the primary objective of the study were scientifically and schematically presented in this review paper. Results: The psychophysiological effect of karate training and their relation with brain functions have been elaborated. This review compiles the few studies established on the cognitive benefits of karate through the electrical stimuli and neurochemical release. Conclusion: Karate may be effective in advancement of particular brain functions and neurocognitive actions through a life time. Electrophysiological studies have unraveled improved neural efficiency, stress tolerance, working and muscle memory but need further exploration. Similarly, to better understand the effects of karate on neurochemical secretions, further research involvement is required.

Effect of regular yogic training on growth hormone and dehydroepiandrosterone sulfate as an endocrine marker of aging.

Growth hormone (GH) and dehydroepiandrosterone sulfate (DHEAS) secretion decline with advancing age and are associated with the symptoms of aging. Yogic texts claimed that regular practice of yoga may restore and maintain general endocrinological properties in the human body. Objective of the Study. To observe the effect of yogic training for twelve weeks on basal level of GH and DHEAS in middle aged group. Method. Forty-five untrained volunteers were divided into two groups, that is, yoga practicing (experimental: male 15, age 42.80 ± 7.43 yrs; female 8, age 44.75 ± 8.40 yrs) and waitlisted control group (male 15, age 41.67 ± 7.87 yrs; female 7, age 45.43 ± 7.00 yrs). The experimental group underwent combined yogic practices daily in the morning for 6 days/week for 12 weeks, whereas control group continued their usual routine activities. Standing height, body weight, body mass index, and basal level of GH and DHEAS were measured before commencement and after six and twelve weeks of yogic training period. The repeated measure ANOVA was used for data analysis. Results. 12 weeks of yogic training produces a significant increase in GH and DHEAS for both male and female groups as compared to their baseline data, whereas no as such changes were observed in the control group. Conclusion. Combined approach of graded yogic training may be beneficial for maintaining the basal level of GH and DHEAS in the human body, thus promoting healthy aging.
