Correlation of Lower Limb Muscles and Body Mass Index with Body Balance in the Elderly
Folia Medica Indonesiana
Indonesia enters the ageing population because of increasing elderly population. The large number of ederly population can have negative impact if they have some problems, such as increased disability and increased rates of life dependence. Based on health research, it was mentioned that the cause of the most injuries to the elderly group is falls that are caused by balance disorder. Balance problems can be caused by changes of musculoskeletal function. In addition, Body Mass Index (BMI) is still a problem that often occurs in the elderly that can affect daily activities. The objective of this study was to prove that lower limb muscle strength and BMI have correlation with body balance in the elderly. This study used a cross-sectional method carried out on individuals from affordable populations with Kendall Tau C data analysis. Thirty-nine respondents were selected based on inclusion and exclusion criteria. Data were taken from these respondents on weight and height measurement for...

Background: Falls are a major health issue in the elderly people and an important cause of bone fracture. The aim of this study was to determine the association between quadriceps muscle strength (QMS) and falls in the elderly subjects. Methods: All eligible participants of the Amirkola Cohort Study entered the study. Data regarding demographic characteristics, clinical and laboratory examinations were provided between 2011 to 2014. Occurrence of falls during previous year was determined by interview and review of the medical records. The study patients were divided into low, moderate and high muscle strength groups according to QMS values ≥ 30, 15-30, and < 15 kg respectively). Association between muscle strength and falls was determined by using multiple logistic regression analysis with calculation of odds ratio (OR). Results: A total 1028 participants (females, 44.3%) were analyzed and 178(17.3%) subjects experienced a fall. Individuals with falls had higher age (p = 0.001) and lower QMS value (p = 0.001). After adjustment for all clinical and demographic variables, occurrence of falls was negatively associated with QMS and positively associated with age > 70 years old. Compared to group with QMS ≥ 30 kg, the prevalence of falls in low and moderate QMS groups increased by OR = 3(95% CI, 1.78-5.05) and 2.18 (95% CI, 1.22-3.42) respectively. Conclusion: These findings indicate that older subjects with lower QMS are at greater risk of falls. These findings provide a rational for muscle strengthening exercise in older people.
Effect of 4 Week Simple Balance Exercise on Balance Ability in Thai Elderly
The objective of this study was to evaluate the short-term effects of 4 weeks balance training program by using simple daily activity living exercise training program on balance ability in Thai elderly person. Forty two participants (36 females and 6 males) were randomly divided into two groups: training (n=21) and control group (n=21). In exercise group, simple balance training was performed at nursing home and controlled by the researcher. Participants were trained once per day, 5 days per week for 4 weeks. In control group, participants were asked to maintain their normal physical activities throughout the experimental period. The two groups of subjects were assessed their balance abilities using single leg balance time test (SLBT) and 3-m timed up and go test, (TUGT) at pre-and post-training program. Balance ability was compared between exercise and control group using Mann-Whitney U test. Within group comparison was used Wilcoxon matched-pair signed-rank test. The level of statistically significant difference for all analyses was set at p-value less than 0.05. The results found that after 4 weeks, the improvement of balance abilities was demonstrated by increment of SLBT and decrement of TUGT in exercise group (P < 0.05). Moreover subjects in exercise group achieved significantly higher of percent change in the balance ability than subject in control group (P < 0.05). The present study indicated that the designed balance training program used in this study has shown successful effects on improving balance ability for the elderly to prevent falls. Since its ease to use and simply to perform anywhere, anytime in every household, therefore this program should be recommend for the elderly people.

| Background: muscle strength and power are two factors affecting balance. The impact of muscle strength and power on postural control has not been fully explored among different age strata over sixty. Objectives: the aim of the present study was to assess the muscle strength and power of elderly women in different age groups and determine their correlation with postural control. Method: eighty women were divided into four groups: the young 18-30 age group (n=20); the 60-64 age group (n=20); the 65-69 age group (n=20); and the 70-74 age group (n=20). The participants underwent maximum strength (one repetition maximum or 1-RM) and muscle power tests to assess the knee extensor and flexor muscles at 40%, 70%, and 90% 1-RM intensity. The time required by participants to recover their balance after disturbing their base of support was also assessed. Results: the elderly women in the 60-64, 65-69, and 70-74 age groups exhibited similar muscle strength, power, and postural control (p>0.05); however, these values were lower than those of the young group (p<0.05) as expected. There was a correlation between muscle strength and power and the postural control performance (p<0.05). Conclusion: despite the age difference, elderly women aged 60 to 74 years exhibited similar abilities to generate strength and power with their lower limbs, and this ability could be one factor that explains the similar postural control shown by these women.

Elderly is the process of slowly disappearing the ability of tissues to repair themselves / replace and maintain their normal structure and function so that they cannot survive the traces (including infection) and repair the damage suffered. Problems that are often experienced by the elderly are decreased bone density and balance problems. In every body activity or movement, the body will always need balance both statically and dynamically so that the position of the human body becomes stable and reduces the risk of falling. This study aims to determine the effect of elderly exercise on bone density and balance in the elderly at the Hati Mulia Foundation, Takalar Regency. This study uses a quasi-experimental research design with a pretest-post-test one group design. The research population is the elderly at the Hati Mulia Foundation, Takalar Regency. The number of samples was 30 people who were divided into 2 groups, namely the control group carried out by the Batara Hati Mulia Gowa...
Quadriceps muscle strength and dynamic stability in elderly persons
Gait & Posture, 1999
Several measures of dynamic stability during two functional activities correlated to quadriceps femoris muscle strength. A total of 34 disabled elders (aged 60-88) living in the Boston area consented to maximum isometric quadriceps muscle strength testing, chair rise and gait analysis. During chair rise, quadriceps strength significantly correlated with maximum upper body vertical linear momentum, r=0.53, PB0.005, anterior posterior linear momentum, r= 0.38, PB 0.05, and the time to complete the chair rise, r= −0.48, PB0.05, n= 29. Stride length and gait velocity correlated (r= 0.56, P B 0.001 and r= 0.51, P B 0.002, n=34) with quadriceps muscle strength. The maximum range of whole body anteroposterior (A/P) linear momentum during gait also correlated with quadriceps strength (r=0.47, P =0.004, n = 31). Dynamic stability during chair rise and gait, at preferred speed, correlates directly with quadriceps femoris muscle strength in functionally limited elderly individuals. In our sample, elders performed one of three movement strategies to arise from a chair, and quadriceps strength did not statistically differ between the chair rise strategy groups. However, persons with the greatest quadriceps strength values were more stable regardless of which chair rise strategy they performed. Our data indicate that clinicians should not suggest that patients use compensatory momentum inducing locomotor strategies unless the patient has sufficient strength to control these induced forces.

Although the sit-to-stand (STS) test score has been shown to relate to the strength and size of the quadriceps femoris (QF) for elderly population, it is unknown whether this relationship is influenced by a posture (i.e., the trunk being allowed to stoop or not) during the STS test. The present study investigated the relationship between STS test score and QF anatomical cross-sectional area (ACSA) in the middle-aged and elderly population with regard to the difference in the posture during STS test, and aimed to develop an accurate predicting equation of the QF ACSA from the STS test score. 105 males (40-81 years) and 113 females (41-79 years) participated in the present study, then the subjects were divided at random as validation and cross-validation groups. Mid-thigh QF ACSA was determined by magnetic resonance imaging. Subjects performed a 10-repeated STS as fast as possible in two conditions: (1) with the trunk being allowed to stoop during the sitting phases, and (2) kept upri...

This study has been conducted in order to investigate whether quadriceps femoris and hamstring muscular force of elite athletes having an active sports life, affects the static and dynamic balance performance. The study has included 16 elite athletes with an active sports life totally. Quadriceps femoris and hamstring muscular force of the athletes have been measured by Pressure Air Biofeedback Test method. The balance performances have been evaluated by using Biodex Balance System, and determined as dynamic and static. Pearson Correlation test has been applied in the statistical evaluation of the study. It has been found out that the static balance performances and oscillation indexes of the athletes have not changed in accordance with femoris muscular force of the athletes (p>0.05). When dynamic balance performances are taken into consideration, it has been detected that as difficulty level increases, quadriceps femoris muscular force also affects the balance performance (p<...
Quadriceps muscle strength in healthy individuals of different age groups: A cross sectional study
International Journal of Applied Research, 2022
During young adulthood (20-35) years of age, both biological function and physical performance reach their peak. The degeneration of muscle strength with aging is due to the overall decrease in muscle mass, especially the type II muscle fibres. And the lower extremity is more affected by aging than the upper extremity due to less use of lower limbs than upper limbs in daily activity. Thus, this study wanted to find out the quadriceps muscle strength among healthy individuals of different age groups. Methodology: A cross sectional Study was conducted on 120 healthy individuals. Subjects were selected based on the inclusion criteria. (I) Four equal sized groups, 20-25, 25-30, 30-35, 35-40 years of age, without any neurological and orthopaedic disorders Persons with diabetes/thyroid and lower limb injuries, with concurrent Musculoskeletal, Neurological, Cardiovascular disorders. Were excluded. Quadriceps muscle strength were assessed by using micro FET2 Dynamometer. Results: By Applying ANOVA significant difference was found in quadriceps strength among different age groups (p-value is < 00001.) Conclusion: This study concluded that quadriceps muscle strength varies among different age groups of healthy individuals.
