Item Comparative study of nerve conduction parameters in peripheral nerves of upper limb (dominant hand) in mobile users with different usage time and type(Mrs Dipika Charan of MedScience (India) Publications, 2022-08) Dubey, N; Sahu, A; Arora, J.Background: With the advancement in digital world, but smart phone usage has increased among all age groups but youngsters are involved in heavy gaming on smart phones which has led to increased risk of ill-effects especially on eyes and hands. Aim and Objectives: The study was designed to study the ill-effects of excessive usage if smart phones on peripheral nerves of hands especially of dominant hand among young adults. Materials and Methods: Nerve conduction study was performed on 100 young adults who were divided into three groups on the basis of mobile usage time. Nerve conduction velocities as well as distal latencies of motor and sensory nerves of the dominant hand were measured among different groups. Results: One-way ANOVA test was applied to study the results among different groups. Although no significant difference in conduction velocity or latency was observed in motor or sensory nerves among three groups, Ulnar sensory conduction velocity has been found to be slow as well as distal latency was found to be prolonged in third group with heavy usage of smart phones as compared to other groups. Conclusion: The reason for the above results could be due to less usage time in hours as well as in years due to which no significance differences were observed in conduction velocity/distal latency in our study. Hence, further studies are suggested with more sample size and more usage time in terms of years as well as in hours.Item Effect of body mass index on VO2 max among apparently healthy male young adults: A cross-sectional study(Mrs Dipika Charan of MedScience (India) Publications, 2022-06) Dubey, N; Roy, P; Arora, J.Background: Factors determine the change in aerobic capacity (VO2 max). This study discovered an association between body mass index (BMI) with aerobic capacity (VO2 max) in apparently healthy male young adults. Aims and Objectives: The study aimed to determine the effect of obesity on cardiopulmonary health of apparently healthy male young adults with following objectives: (i) To compare the VO2 max in different BMI groups and (ii) to study the correlation of BMI with VO2 max. Materials and Methods: A study was conducted among 100 male subjects of 18–30 years assessing BMI (height/weight2) and VO2 max by CPET Ergo-bike machine. Statistical analysis was done with unpaired t-test. Results: In correlation between four BMI groups and their respective VO2 max, we found that VO2 max in the underweight group (BMI <18.5) is positively correlated and statistically significant. In the normal group (BMI 18.5–24.9), it is negatively correlated and insignificant. In the overweight group (BMI 24.9–29.9), it is negatively correlated and significant and in the obese group (BMI ?30), it is negatively correlated and not significant. Conclusion: VO2 max is gradually increasing with BMI toward the normal range and decreasing away from the normal range significantly in both underweight and overweight groups. Whereas, this change of VO2 max is not so significant in both normal and obese groups as per. As BMI is inversely related to cardiopulmonary function, persons having high BMI can be motivated toward a healthy lifestyle.
