Introduction: This study aimed to investigate the onset time and the electromyographic activity level of the selected lower limb muscles in the active and inactive old women.Materials and Methods: In this case-control study, 28 old women with a Mean±SD age of 61.07±0.88 years were selected in the inactive (15 people) and active (13 people) groups. The electrical activity of the selected muscles of the lower limbs was collected by the EMG device in a stair down movement. Results: The onset time of tibialis anterior, vastus lateralis, and biceps femoris muscles are faster in the active group (p <0.05). Besides, the activity level of the rectus femoris muscle in the interval of 100 ms before the initial contact and the ratio of the vastus medialis muscle to the biceps femoris muscle was significantly lower (p <0.05) in the active group.Conclusion: It seems that the muscles of the lower limbs in the group of women with regular physical activity are activated faster than the inactive group and the decrease in the activity of the rectus femoris muscle and the ratio of the vastus medialis to the biceps femoris muscle in the active women may be accompanied by fatigue and reduced intra-articular forces. Therefore, it is recommended that old women participate in regular and active exercise programs to improve their onset times of muscle activity.

As people get older some may experience reduced mobility and more physical challenges that can affect their quality of life negatively. The research focused on investigating how two different types of training programs sensori-motor and Otago affect the abilities, functional balance and overall well being of men.This study was semi-experimental. This research included 45 men aged 65 to 70 who were selected in an accessible and purposeful and then randomly divided into three groups.. With 15 individuals, in each group, for sensorimotor training group the Otago training group and a control group. Respective exercise groups underwent a total of 24 training sessions done in 8 weeks. To measure abilities and being impact effectively, in this study various assessment methods were used such as Short Physical Performance Battery (SPBB) tests together with time up and go (TUG) evaluations besides implementing SF36 quality of life survey questionnaire. ANOVA and paired sample t-tests were done for data analysis with a significance level set at p≤ 0.05 using SPSS software version 23. The outcomes showed a Significant different, in groups prior and post exercise experimental (p=0.001). Significant variations were noted in the test results when comparing the sensorimotor and Otago groups to the control group at a significance level of p=0.001 for inter group comparisons; whereas no notable variations were observed among the groups during the pre test phase.Both sensorimotor and Otago exercises effectively enhance physical performance, functional balance, and quality of life in elderly men. Since no significant difference was found between the two experimental groups, it can be concluded that either type of exercise can be beneficial for improving these aspects of
