    Acute supplementation of 200 mg Panax ginseng (PG) or 30 gm honey (H30) or 60 gm honey (H60) imparted beneficial effects on endurance performance parameters. This self-controlled double-blind study was conducted in 12 healthy males (aged 20-25 years) to assess whether combination of H30 and PG (H30PG) or combination of H60 and PG (H60PG) could be more effective than placebo (PL) in enhancing endurance exercise performance. Heart rate and rate of perceived exertion (RPE) were recorded after every 10 minutes. Blood samples were taken before supplementation and at exhaustion for analysis of glucose, insulin, lactate, free-fatty-acids, lipid peroxidation, superoxide-dismutase, catalase, and total-thiol. Data were analyzed by paired t-test and one-way ANOVA with post-hoc analysis. Endurance time was significantly (p<0.05) higher in H60PG trial followed by H30PG trial compared to PL trial. Experimental trials showed significantly (p<0.05) higher values than PL trial in exercise heart-rate, RPE, glucose, insulin, catalase, superoxide-dismutase, and total-thiol while significantly (p<0.05) lower values in plasma lactate, free-fatty-acid, and lipid-peroxidation. Though no significant change was observed between H60PG and H30PG trials, yet H60PG showed better result than H30PG. Thus, ingestion of H30PG and H60PG exerted better ergogenic effect than PL in healthy adults.

    The goal of this study was to examine the prevalence of musculoskeletal disorders (MSDs) among nursing personnel in different hospitals and nursing homes of West Bengal, India and to assess various work-related factors as the causative elements contributing towards MSDs. Maintaining the inclusion and exclusion criteria of this study, 58 registered nurses were chosen. Modified Nordic Questionnaire and Copenhagen Psychosocial Questionnaire (COPSOQ) were used. Percentage analysis, Correlation analysis, and χ2 tests were performed. Almost 90% of the total population (N = 58) complained of various types of MSDs. The most prevalent one among them was lower back pain (LBP) (62.1%). LBP and ankle/feet pain showed significant correlations with some demand and job content scales of the COPSOQ. 74.1% and 25.9% of subjects belonged to the high and low demand category respectively, likewise, 75.9% and 24.1% were in the high and low job content category. For LBP and job demand, χ2 (1) = 10.771, p = 0.001 and for LBP and job content, χ2 (1) = 4.383, p = 0.036. MSDs are highly frequent in the nursing profession and LBP is the most recurrent one. High physical and psychological demands imposed stronger effects than job content factors on MSDs.

    Traffic policing is always an exigent and difficult assignment due to its occupational needs and working conditions. They are vulnerable to musculoskeletal disorders as they have an awkward posture on and off the road, prolonged standing, and continuous repetitive movement of their shoulders and hands, causing rigorous stress. The study is aimed at assessing the effect of occupational stress on the musculoskeletal health of traffic police personnel in Kolkata. A modified Nordic Musculoskeletal Questionnaire was used to interview and a BPD score rating was used to measure discomfort. OWAS and RULA methods are used to assess the postural analysis. The most frequent types of pain include low back pain, neck pain, knee pain, and upper back pain. Cops exposed on the roads mostly felt lower back pain due to prolonged standing for four to six hours, and often even more than six hours. Posture analysis showed they are in medium-risk zone. Prolonged and unforeseen duty hours, insufficient manpower, and variable workplaces create physical stress on them, while prolonged static posture causes muscle and joint pain, thighs, knees, and ankles, and even injuries. Regular physical exercise, frequent medical check-ups, and healthy food intake are being suggested to cope with health problems.
