ABSTRACT
Objective: Memory is formed on the basis of sensory stimuli perceived. Vision and Auditory sense are the most common modes to form visual and auditory memory. This study was planned to find the preferred sense route for the formation of memory, between the two genders. Method: In the present cross sectional experimental study, 40 male and 40 female subjects between 18- 20 years of age were tested for visual & auditory memory. Results: The results suggested statistically significant higher scores of ‘Memory Test’ in women in comparison to men (F479 3.312, p=<0.001). The mean score for memory subtests was best for black & white pictures followed by colored pictures, visual words, visual digits, auditory digits and auditory words in that order in men, whereas in women, mean score was best for colored pictures followed by black & white pictures, auditory words, auditory digits, visual words and visual digits. Conclusion: It may be concluded that in men visual sense and in women auditory sense are more effectual for the formation of memory.
ABSTRACT
The effect of short term (12 weeks) physical exercise on serum total testosterone level was evaluated in 30 young male adults, aged 18-27 years (mean age 21.67±2.26 years). These medical students, having sedentary life style underwent heavy exercise by attaining heart rate 125-150 beats/min on bicycle ergometer for 15 min on alternate day basis amounted to 670 kilopond metre per minute work done and percentage of VO2max was 71±3. Pre-exercise serum total testosterone levels (5.49±1.31) of students were compared with those obtained after 1 week and 12 weeks of initiation of exercise. The serum total testosterone was measured by DRG Testosterone ELISA kit. After 1 week of exercise, a statistically insignificant decrease (5.488±1.32; P>0.05) was found while after 12 weeks of exercise, a statistically significant increase (6.41±2.28 P<0.05) was noticed between the pre-and post-exercise serum total testosterone levels. We conclude that short-term exercise produces an elevation in serum testosterone levels in young adults.
