Objective:To observe the effect of different exercise methods on the prevention and treatment of senile sarcopenia.Methods:A cross-sectional investigation was carried out to select the elderly who visited the First Affiliated Hospital of Zhejiang University School of Medicine and Tongxiang Hospital of Traditional Chinese Medicine from October 2016 to December 2023 for medical check-ups at the geriatrics department and physical examination center.General information was collected, and the Hologic Discovery-Wi bone density scanner(Hologic, USA)was used to measure appendicular lean mass(ALM).Walking speed over 6 meters and grip strength were measured, and the appendicular skeletal muscle index(ASMI=limb muscle mass/height 2)was calculated.The subjects were divided into three groups aged 60-69, 70-79, and 80-89 years and the relevant information was obtained through standard questionnaires.Based on the exercise methods and time, each age group was categorized into three groups: non-exercise, aerobic exercise, and resistance exercise.Differences in related indicators of sarcopenia among the elderly in different age groups with different exercise methods were analyzed. Results:In all three age groups, the ASMI of the resistance exercise group was higher compared to the aerobic exercise and non-exercise groups: In the 60-69 years old group, (7.50±0.31)kg/m 2vs.(6.93±0.37)kg/m 2 and (6.81±0.27)kg/m 2, F=38.146, P<0.001; In the 70-79 years old group, (7.26±0.30)kg/m 2vs.(6.82±0.38)kg/m 2 and (6.50±0.36)kg/m 2, F=35.784, P<0.001; In the 80-89 years old group, (7.00±0.59)kg/m 2vs.(6.53±0.63)kg/m 2 and (5.89±0.66)kg/m 2, F=23.380, P<0.001.The resistance exercise group also had higher grip strength than the aerobic and non-exercise groups: In the 60-69 years old group, (39.23±1.78) kg vs.(26.21±4.79) kg and (24.68±3.55) kg, F=127.806, P<0.001; In the 70-79 years old group, (37.78±2.50) kg vs.(27.21±5.47) kg and (24.43±3.49) kg, F=75.265, P<0.001; In the 80-89 years old group, (28.75±4.71) kg vs.(21.37±5.57) kg and (17.08±4.50) kg, F=33.148, P<0.001; Both the resistance and aerobic exercise groups had a faster walking speed compared to the non-exercise group: 60-69 years old group (1.30±0.14) m/s and (1.31±0.15) m/s compared to (1.20±0.14) m/s, F=5.905, P=0.003; 70-79 years old group (1.26±0.13) m/s and (1.24±0.17) m/s compared to (1.16±0.16) m/s, F=4.931, P=0.009; and (1.00±0.20) m/s and (1.02±0.27) m/s over (0.84±0.24) m/s in the group of 80-89 years old, F=6.913, P=0.001.The results of two-by-two comparisons showed that among the older adults in the 70-79 and 80-89 age groups, ASMI was higher in the aerobic exercise group than in the non-exercise group ( t=0.070, 0.048, both P<0.001), and grip strength was higher in the aerobic exercise group than in the non-exercise group ( t=0.885, 0.976, P=0.002, <0.001); however, there was no difference in step speed between the resistance exercise group and the aerobic exercise group among older adults in the three age groups ( t=0.031, 0.035, 0.701, P=0.605, 0.593, 0.841). Conclusions:Compared with non-exercise and aerobic exercise, resistance exercise has a clear effect on the prevention and treatment of sarcopenia in the elderly.As age increases, aerobic exercise can also prevent and treat sarcopenia in the elderly aged 70-89 years.Both resistance exercise and aerobic exercise have obvious effect on maintaining the pace of the elderly.

Bedridden patients mostly use the back cushion object,raise the bedside position,and other methods to obtain the semi-decumbent position.However,the existing methods have shortcomings such as insufficient execution,wrong angle estimation,weak consciousness,forgetting,decreased comfort,easy to cause pressure sore and aspiration pneumonia.To solve the shortcomings of the existing eating position placement method,the department of geriatric medicine team of Tongxiang City Hospital of Traditional Chinese Medicine designed a bed-rest pillow for bed patients to eat or other requirements of semi-lying position,and obtained the National Utility Model Patent of China(patent number:ZL 202122859891.4).This device places the pillow on a flat bed,with the back of the pillow next to the head of the bed for support and to prevent sliding.The patient was placed in a retainer slot,head in the first retainer slot,shoulder and back in the second retainer slot,waist and abdomen in the third retainer slot,and hands on the armrests on both sides of the pillow.The use of pillows for bedridden patients is simple and easy to learn,convenient,economical and practical,time-saving and labor-saving,and convenient supervision and inspection,which can reduce complications such as aspiration and pressure ulcers,thereby reducing the economic burden of the patient,improving the quality of life,and improving the satisfaction of patients and their families,and is worthy of clinical promotion and use.
