Correlation between concern about falling and functional muscle fitness in community-dwelling elderly / Correlação entre preocupação em cair e aptidão muscular funcional em idosos comunitários

Abstract Introduction: To establish a correlation between concern about falling and a more comprehensive functional parameter, functional muscle fitness, a variable that encompasses functional components such as balance, muscle strength, power, flexibility and motor coordination in an integrated way. Functional muscle fitness is measured using the sitting-rising (from the floor) test (SRT), a simple, safe, fast and ecological test. Objective: The aim of our study was to determine the correlation between concern about falling and functional muscle fitness in the elderly. Methods: A cross-sectional observational study was conducted. The sample consisted of 53 elderly people of both sexes (86.8% women; 65.6 ± 4.7 years old; body mass index 28.5 ± 3.8 kg/m2), who were assessed for concern about falling (through Falls Efficacy Scale International, FES-I-Brazil) and functional muscle fitness (through SRT). Correlation analysis was performed using the Spearman test. For all analyses, a significance level of 5% (p < 0.05) was established. Results: Concern about falling showed a negative correlation with functional muscle fitness (rho =-0.229; p = 0.015). Conclusion: Elderly people with lower levels of functional muscle fitness have a higher level of concern about falling.

A aptidão muscular funcional é mensurada por meio do teste de sentar e levantar do chão (TSL), um teste simples, seguro, rápido e ecológico. Objetivo: A pesquisa teve como objetivo verificar a correlação entre a preocupação em cair e a aptidão muscular funcional de idosos. Métodos: Trata-se de um estudo com delineamento observacional do tipo transversal correlacional. A amostra foi composta por 53 idosos de ambos os sexos (86,8% mulheres; 65,6 ± 4,7 anos; índice de massa corporal 28,5 ± 3,8 kg/m2), avaliados quanto à preocupação em cair (através da Escala Internacional de Eficácia de Quedas Brasil - FES-I-Brasil) e à aptidão muscular funcional (através do TSL). A análise de correlação foi realizada pelo teste de Spearman. Para todas as análises foi estabelecido um nível de significância de 5% (p < 0,05). Resultados: A preocupação em cair apresentou correlação negativa com aptidão muscular funcional (rho =-0,229; p = 0,015). Conclusão: Idosos com menores índices de aptidão muscular funcional apresentam maior nível de preocupação em cair.

Relationship between muscular fitness and quality of life as well as psychological distress in radiotherapy patients with cervical cancer / 中南大学学报(医学版)

OBJECTIVES@#Patients with cervical cancer who have received radiotherapy often suffer from systemic muscle volume reduction and quality of life decline due to systemic effects of tumor and side effects of radiotherapy. The purpose of this study was to investigate the status of muscle fitness, quality of life, and psychological pain in patients with cervical cancer who received radiotherapy, and to explore the correlation between muscle fitness, quality of life, and psychological pain.@*METHODS@#A total of 202 cervical cancer patients aged 19-71, who received radiotherapy in Hunan Cancer Hospital from July 2020 to February 2021, were selected by convenience sampling method. Functional Assessment of Cancer Therapy Cervix (FACT-CX) and Distress Thermometer (DT) were used for the survey. The patient's grip strength was assessed by a handgrip meter and compared with that of healthy Chinese women of the same age. The correlation between muscle fitness and quality of life and psychological pain was analyzed.@*RESULTS@#The grip strength of cervical cancer patients receiving radiotherapy was significantly lower than that of healthy Chinese women at the same age (@*CONCLUSIONS@#The grip strength of patients with cervical cancer undergoing radiotherapy is generally decreased, which is affected by many factors, and is closely related to the quality of life and psychological pain of patients. In the future, dynamic attention should be paid to the changes of grip strength and related functions in patients receiving radiotherapy for cervical cancer, the potential risks in the treatment should be identified early, and targeted intervention should be taken.

Kaastu training for muscle fitness in the middle-aged and elderly adults: Effects and strengths / 中国组织工程研究

BACKGROUND: KAASTU training combined with low-load exercise can achieve the same effect as traditional high intensity resistance exercise. Therefore, it has been widely used in competitive sports, sports fitness, medical rehabilitation and other fields in recent years. However, there are few comments on the effects of KAASTU training on muscle fitness of the middle-aged and elderly adults. OBJECTIVE: To further explain and verify the safety, practicability and convenience of KAASTU training in the middle-aged and elderly adults exercise through a comprehensive review of the muscle fitness of middle-aged and elderly adults, and to provide scientific suggestions for the middle-aged and elderly adults to choose a safe and effective exercise. METHODS: Up to October 2019, Elsevier, PubMed, Springer, VIP, CNKI and Taiwan Academic Literature Database were searched for Chinese and English literature about KAASTU training, blood flow restriction, and muscle. Corresponding selection criteria was established according to the needs of the study, followed by literature screening. RESULTS AND CONCLUSION: KAASTU training combined with low-load exercise can effectively increase the muscle mass of the middle-aged and elderly adults, and has a positive effect on the prevention of muscle atrophy in the middle-aged and elderly adults. KAASTU training combined with low-load exercise can effectively improve the muscle strength of the lower extremities, which is beneficial to reduce exercise injury and improve the quality of life. KAASTU training has positive effects on bone health of the middle-aged and elderly adults, improves osteoporosis and increases bone mineral density of the older adults. Compared with traditional resistance training, KAASTU training is characterized by lower load and better effect. Therefore, KAASTU training is easier to be accepted by the middle-aged and elderly adults.
