Muscle-Strengthening Exercise Links with Lower Odds for Depression in Adolescents

Purpose:Physical activity is a well-recognized protective factor against depression in adolescents.As a compo-nent of physical activity,muscle strengthening exercise(MSE)is also viewed as a correlate associated with lower risks of depression in adults.However,little is known about the association in adolescents.This study aimed to explore the association between MSE and depression in a sample of Chinese adolescents.Method:A self-reported questionnaire was used for data collection including variables of MSE,depression(assessed by Children’s Depres-sion Inventory)and selected sociodemographic factors(e.g.,sex,grade,height and weight[for body mass index]).Generalized Linear Models was utilized to estimate the association between MSE and depression.Results:Results showed a negative association between MSE and depression(Beta=–0.66;both MSE and depression were treated as continuous variables).When treating MSE(meeting or not meeting the recommendations)and depression as binary variables,odds ratio for depression in adolescents not meeting the MSE recommendation was significant higher(odd ratio=1.50,95%CI:1.15–1.96)than those meeting the MSE recommendations.Conclusions:This study found that MSE may be a protective factor against MSE in adolescents.Future studies are encouraged to confirm or negate our studyfinding using improved study design.

Effects of virtual reality balance games combined with muscle strength training on balance function and motor ability of Parkinson's patients

Objective To investigate the effects of virtual reality balance games combined with strengthening muscle training on balance function and exercise capacity in patients with Parkinson's disease.Methods Sixty patients with Parkinson's disease were selected from January 2018 to October 2019.The random number table method was divided into the control group(n=30)and the observation group(n=30).Both groups were given conventional drugs and For rehabilitation training,the observation group was given a virtual reality balance game combined with strengthening muscle training.The upper limbs,lower limbs,balance function,comprehensive rehabilitation effect and daily living ability were compared before and after training.Results After training,the Brunnstrom score,FMA-UE,FMA-LE score,and cadence score of the two groups of patients increased.The common contraction rate(CR)of the biceps brachii in elbow flexion and the three heads of the brachii in elbow extension Muscle CR,standing walking test,10m walking test,reduced left and right step difference,and the observation group was better than the control group,which was significant(P<0.05).Conclusion Patients with Parkinson's disease have improved their upper and lower extremity motor capacity and balance function through virtual reality balance games combined with strengthening muscle training,which can improve the overall rehabilitation effect and ability of daily living.

“Lifting More” is Associated with Lower Risks of Depression in University Students

Research on the population in western world showed that,MSE(muscle-strengthening exercise)is beneficial to the treatment of mental disorders.However,the situation in Chinese adults is little known.For this reason,the study is performed to understand the connection between depression and MSE among college and university students in China aged between 18 to 24.1793 college students have been recruited,and their average age is 20.67.A questionnaire has been developed and it is self-reported and designed to collect information about MSE and participants,including body mass index and sex and so on.Sleep and physical activity have been evaluated by introducing two scales,that is,Pittsburgh Sleep Quality Index and International Physical Activity Questionnaire-Short Form,respectively.Moreover,Patient Health Questionnaire-9 has been adopted to indicate the severity of depression of participants.The link between depression and MSE has been studied by introducing multilevel linear regression.Among all these study participants,just 24.87%of them met the MSE standards of World Health Organization,that is,more than 2 days every week.The average depression score was 6.80(±5.19).Greater num-ber of days for MSE shows negative association with the depression,with (beta=-0.17,95%CI:-0.31 to-0.03,p=0.015).Those students failing to meet MSE standards are more susceptible to the depression risk(beta=0.63,95%CI:0.09–0.19,p=0.027).The results show that,there is a relationship between MSE participation and relieved status of depression among young adults in China.Interventions designed to relieve depression can be developed on the basis of MSE.

Advances in the research and application of high-intensity focused electromagnetic technology for fat apoptosis and body shaping

With improvements in living standards and advancements in medical technology,the demand for fat reduction and body shaping is increasing.Non-invasive fat reduction and body shaping therapy has gradually become a research hotspot in plastic surgery.High-intensity electromagnetic technology,a non-invasive treatment that can reduce subcutaneous fat and strengthen muscle,has been increasingly applied in clinics in recent years.This article reviews the fat reduction and body shaping mechanism and clinical effects of this equipment and provides a reference for its clinical application.
