Hand Grip

Latar belakang genggaman tangan merupakan indikator yang dapat digunakan untuk mengevaluasi status gizi dan juga kekuatan fisik. Uji  kekuatan genggam tangan merupakan salah satu penilaian yang dapat digunakan dengan mudah dan cepat dalam berbagai pelayanan kesehatan untuk memperoleh hasil yang akurat. Tujuan dari penelitian ini adalah untuk menganalisis apakah terdapat hubungan antara kekuatan genggam tangan dengan indikator antropometri dan komposisi lemak tubuh pada mahasiswa kedokteran. Metode yang digunakan adalah cross sectional dengan melibatkan seratus empat puluh mahasiswa kedokteran dibagi menjadi dua kelompok. Analisis pada kelompok pertama (n=78) dilakukan pengukuran kekuatan gengam tangan beserta indeks masa tubuh (IMT) dan lingkar lengan atas (LILA). Sedangkan kelompok kedua (n=62) diukur kekuatan genggam tangan beserta komposisi tubuh (komposisi lemak dan air serta lean mass). Pengukuran status gisi dilakukan dengan menggunakan timbangan digital dan pengukur tinggi badan sedangkan pita Medline untuk lingkar lengan atas (LILA). Kekuatan genggam tangan diukur menggunakan hand grip dynamometer sedangkan komposisi tubuh dianalisis dengan handheld bio-impedance analysis (BIA). Hasil penilaian IMT, LILA, komposisi air dan lemak menunjukkan nilai yang lebih tinggi (p<0,05) pada pria kecuali lean mass. Korelasi ditunjukkan antara kekuatan genggam tangan dengan IMT (r=0,48; α<0,05), LILA (r=0,43; α<0,05), proporsi lemak (r=0,73; α<0,05), dan lean mass (r=-0,37; α<0,05). Kesimpulan mahasiswa pria memiliki nilai IMT, LILA, dan komposisi lemak tubuh yang lebih tinggi dibanding mahasiswa wanita. Kekuatan genggam tangan meningkat secara konsisten seiring dengan meningkatnya indeks masa tubuh (IMT), lingkar lengan atas (LILA), dan proporsi lemak tubuh, tetapi menunjukkan korelasi negatif dengan lean mass.

Background and objectives: The objective of this study was to establish reference values for hand grip strength, compare the results obtained with Collin and Jamar type dynamometers and determine their association with anthropometric and lean mass measurements.Material and methods: This cross-sectional population-based study was undertaken in Pizarra (Málaga, Spain). The grip strength of the dominant hand was measured using Collin and Jamar dynamometers. Skinfolds (triceps, abdominal, biceps of dominant arm and subscapular) were measured, and body composition was estimated. Eight hundred seventeen adults randomly selected from the census were recruited. Dynamometry reference values are presented for the dominant hand, by gender and age groups.Results: No determinations could be made with the Collin dynamometer in 69 women due to the difficulty in grasping the dynamometer. We found significant positive correlations between the measurements with Jamar and Collin dynamometers (r=0.782; p<0.001) and between grip strength and LMI, determined by both dynamometers (r=0.538, p<0.001 and r=0.462, p<0.001 respectively). Malnourished patients according to LMI had significantly lower grip strength than normally nourished patients (p<0.001 por Jamar; p<0.02 for Collin).Conclusions: Dynamometry reference values in the Spanish population are presented. We recommend the use of the Jamar type dynamometer versus the Collin type dynamometer. Hand grip dynamometry is associated with lean mass which confirms its usefulness in nutritional assessment.

High levels of lean mass are important in collision-based sports for the development of strength and power, which may also assist during contact situations. While skinfold-based measures have been shown to be appropriate for cross-sectional assessments of body composition, their utility in tracking changes in lean mass is less clear.Purpose:To determine the most effective method of quantifying changes in lean mass in rugby league athletes.Methods:Body composition of 21 professional rugby league players was assessed on 2 or 3 occasions separated by ≥6 wk, including bioelectrical impedance analysis (BIA), leanmass index (LMI), and a skinfold-based prediction equation (SkF). Dual-X-ray absorptiometry provided a criterion measure of fat-free mass (FFM). Correlation coefficients (r) and standard errors of the estimate (SEE) were used as measures of validity for the estimates.Results:All 3 practical estimates exhibited strong validity for cross-sectional assessments of FFM (r > .9, P < .001). The correlation between change scores was stronger for the LMI (r = .69, SEE 1.3 kg) and the SkF method (r = .66, SEE = 1.4 kg) than for BIA (r = .50, SEE = 1.6 kg).Conclusions:The LMI is probably as accurate in predicting changes in FFM as SkF and very likely to be more appropriate than BIA. The LMI offers an adequate, practical alternative for assessing in FFM among rugby league athletes.

Aerobic exercise training has many known cardiovascular benefits that may promote healthy aging. It is not known if long-term aerobic exercise training is also associated with structural benefits (e.g., lower fat mass, higher areal bone mineral density (BMD) and greater muscle mass). We evaluated these parameters in middle-aged long-term endurance runners compared to sex-, age-, height-, and weight-matched non-running controls. Total and regional lean and fat mass and areal BMD were assessed by dual-energy X-ray absorptiometry. Sagittal magnetic resonance images captured the cross-sectional area and thickness of the lumbar multifidus. Runners (n = 10; all male) had a mean (standard deviation; SD) age of 49 (4) years, height of 178.9 (4.9) cm, weight of 67.8 (5.8) kg, body mass index (BMI) of 21.4 (1.4) kg/m2 and had been running 82.6 (27.9) km/week for 23 (13) years. Controls (n = 9) had a mean (SD) age of 51 (5) years, height of 176.0 (5.1) cm, weight of 72.8 (7.1) kg, and BMI of 23.7 (2.1) kg/m2. BMI was greater in controls (p = 0.010). When compared to controls on average, runners had a 10 percentage-point greater total body lean mass than controls (p = 0.001) and 14% greater trunk lean mass (p = 0.010), as well as less total body (8.6 kg; p < 0.001), arm (58%; p = 0.002), leg (52%; p < 0.001), trunk (73%; p < 0.001), android (91%; p < 0.001), and gynoid fat mass (64%; p < 0.001). No differences were observed between groups for BMD outcomes or multifidus size. These results underscore the benefits of endurance running to body composition that carry over to middle-age.

AbstractThe protocol established for taking hand grip dynamometry measurements determines that the patient must be in a sitting position. This protocol cannot be applied due to the patient’s conditions in some cases, such as abdominal surgery, musculoskeletal spine or hip injuries. The purpose was to determine the reproducibility and level of agreement between the Handgrip dynamometry in supine position with the elbow flexed or extended, and the one measured in the sitting position, the design was a descriptive cross-sectional study. The population were young apparently healthy between 18 and 30 years of age (N = 201). Handgrip measurement was performed on both upper limbs in a sitting position with a flexed elbow, a supine position with a flexed elbow, and supine position with the elbow extended. Reproducibility was nearly perfect in all positions (ICC 0.95–0.97). Regarding the level of agreement for the comparison between sitting and supine positions with a flexed elbow, an average difference of − 0.406. For supine position with an extended elbow and supine position with a flexed elbow, the average difference was − 1.479. Considering the results, clinicians or researchers can choose any of the positions evaluated herein and obtain reliable results as long as the standardization process is followed.

AbstractWe investigated the relationship between trunk muscle mass and spinal pathologies by gender. This multicenter cross-sectional study included patients aged ≥ 30 years who visited a spinal outpatient clinic. Trunk and appendicular muscle mass were measured using bioelectrical impedance analysis. The Oswestry Disability Index (ODI), visual analog scale (VAS) score for low back pain, sagittal vertical axis (SVA), and EuroQol 5 Dimension (EQ5D) score were investigated to evaluate spinal pathology. The association between trunk muscle mass and these parameters was analyzed by gender using a non-linear regression model adjusted for patients’ demographics. We investigated the association between age and trunk muscle mass. We included 781 men and 957 women. Trunk muscle mass differed significantly between men and women, although it decreased with age after age 70 in both genders. Lower trunk muscle mass was significantly associated with ODI, SVA, and EQ5D score deterioration in both genders; its association with VAS was significant only in men. Most parameters deteriorated when trunk muscle mass was < 26 kg in men and < 19 kg in women. Lower trunk muscle mass was associated with lumbar disability, spinal imbalance, and poor quality of life in both genders, with significant difference in muscle mass.

Objective. The aim of the present study was to assess the association between muscle strength, lower extremity function, employment status, and work ability in RA patients. Methods. One hundred seropositive RA outpatients of working age were included in this cross-sectional study. Employment status was assessed by interview and work ability by the Work Ability Index-Single Item Scale (WAS). Muscle strength was determined using dynamometer measurement of isometric hand grip and knee extensor strength. Lower extremity function was measured using the short physical performance battery (SPPB). Regression models estimate the association between unemployment, work ability and muscle strength, and lower extremity function, controlling for sociodemographic and disease-related factors. Results. Forty-one percent of the RA patients were not gainfully employed, and their median work ability had a good WAS value (7.00 [4.00-7.00]). Patients with better knee extensor strength (OR=1.07, 95% CI [1.02-1.12) and better physical performance (OR=1.71, 95% CI [1.18-2.49]) had a significantly better chance of gainful employment. The odds for hand grip strength remained significant when adjusted for sociodemographic (OR=1.5, 95% CI [1.00-1.09]), but not for disease-specific variables. Better hand grip strength (β=0.25, p=0.039) and better knee extensor strength (β=0.45, p=0.001) as well as better lower extremity function (SPPB) (β=0.51, p<0.001) remained significantly associated with work ability following adjustment for sociodemographic and disease-specific variables. Conclusions. The association of employment status and work ability with parameters of physical fitness suggests that improvement in muscle strength and lower extremity function may positively influence work ability and employment in individuals with RA.

Nyha Classification

Introduction: As NYHA Class increases from I (ordinary physical activity does not cause undue fatigue), to Class IV (Symptoms are present while at rest) physical limitations become severe. It has previously been shown that HF patients have increased fat within the muscle thus decreasing exercise performance and tolerance. It is unclear if all NYHA classes are similarly affected. Hypothesis: HF patients with NYHA class III-IV will have more fat and less lean mass than those with NYHA class I-II. Methods: Secondary data analysis using cross sectional data from N=253. The parent study was a multicenter study about nutrition and body composition among patients with HF (preserved or reduced, and NYHA classification I-IV) who had been on a stable medication regimen, able to participate in dual-energy X-ray absorptiometry scan and/or BodPod body composition measures, able to read and speak English, and had no cognitive impairment. Women and men were analyzed separately due to known differences in fat and lean mass. Results: Table 1: Sample characteristic’s Testing the hypothesis using 2-way ANOVA and comparing the percentage of body weight that is lean and fat mass in NYHA class I-II vs III-IV found the interaction of gender and NYHA was not significant in either % lean or %fat (p=0.221, 0.190 respectively). NYHA class by itself was not significant (p=0.067) in %lean but was significant in %fat (p=0.046). Gender was significant in both %lean and %fat with men having 9.6% less fat (1.139 SE) and 9.8% more lean mass (1.066 SE) (p≤0.001). NYHA class III-IV had 2.3% (1.139 SE) more fat than those in NYHA class I-II. The R squared was 0.265 and adjusted R squared was 0.256. Conclusions: Part of our hypothesis was correct in that NYHA class III-IV had more fat mass than those in class I-II, but no difference was found in lean. This is an unexpected finding as healthy people gain fat mass while losing lean mass as they age. Additional studies are needed to further examine this result.

Cutoff Points

Abstract The objective of this study was to improve the cutoff points of the traditional classification of nutritional status and overweight / obesity based on the BMI in a Brazilian sample. A cross-sectional study was conducted on 1301 individuals of both genders aged 18 to 60 years. The subjects underwent measurement of weight and height and bioelectrical impedance analysis. Simple linear regression was used for statistical analysis, with the level of significance set at p < 0.05. The sample consisted of 29.7% men and 70.3% women aged on averaged 35.7 ± 17.6 years; mean weight was 67.6 ± 16.0 kg, mean height was 164.9 ± 9.5 cm, and mean BMI was 24.9 ± 5.5 kg/m2. As expected, lower cutoffs were found for BMI than the classic reference points traditionally adopted by the WHO for the classification of obesity, i.e., 27.15 and 27.02 kg/m2 for obesity for men and women, respectively. Other authors also follow this tendency, Romero-Corral et al. (2008) suggested 25.8 to 25.5 kg/m2 for American men and women as new values for BMI classification of obesity. Gupta and Kapoor (2012) proposed 22.9 and 28.8 kg/m2 for men and women of North India. The present investigation supports other literature studies which converge in reducing the BMI cutoff points for the classification of obesity. Thus, we emphasize the need to conduct similar studies for the purpose of defining these new in populations of different ethnicities.
