Background and Study Aim: Handgrip strength is widely accepted as a functionality parameter to assess upper extremity performance. The measurement of hand grip strength by dynamometry is a low cost, non-invasive method of simple applicability. The present study is based on the association of dominant and non-dominant handgrip strength with demographic and anthropometric characteristics; height, body weight, body mass index, upper arm length, forearm length, hand length, forearm circumference, upper arm circumference. Material and Methods: The study included 70 male athletes in olympic style weightlifting (age: 18.06±2.18, height:1.74±.06 m, body weight: 76.09±13.04 kg). A total of 70 sedentary individuals as a control group (age 18.11±.18, height:1.75±.04 m, body weight: 74.01±13.94 kg) were also taken to compare study findings. The data obtained was analyzed by SPPS for Windows, version 25. Handgrip strength measurements were obtained by a Jamar dynamometer, according to the recommendations of the American Association of Hand Therapists. Results: It was found that the values of dominant and non-dominant handgrip strength, upper arm circumference and forearm circumference length of the weightlifting athletes were higher than those of sedentary individuals (p<.001). No asymmetry was observed in dominant and non-dominant handgrip strength values of the athletes and sedentary individuals. The correlations were noted between dominant and non-dominant handgrip strength values of weightlifting athletes and demographic characteristics, some anthropometric characteristics of upper extremity and weightlifting performance. Conclusion: The variability of handgrip strength might largely be explained by some anthropometric characteristics of upper extremity.

Correlations of Handgrip Strength and some Anthropometric Variables in Indian Inter-University Female Handball Players The purpose of this study was of two-folds, firstly, to evaluate the handgrip strength and some anthropometric characteristics of Indian inter-university female handball players and, secondly, to search the correlations of these physical traits among themselves. To serve this purpose, thirteen anthropometric characteristics, were measured on purposely selected 101 Indian inter-university female handball players aged 18-25 years (mean age 20.13 years, ±1.40) collected from seven Indian universities and the competition was held in Guru Nanak Dev University, Amritsar, India. An adequate number of controls (n = 100, 21.10 years, ± 1.70) were also collected from the same place. The results indicated statistically significant differences (p<.05-.001) in all the variables, except BMI, right upper arm and forearm lengths, right upper extremity length and right upper arm circumference between Indian inter-university female handball players and controls. Dominant right handgrip strength has significantly positive correlations (p≤.01) with all the variables, except left hand width and right upper extremity length. Height and weight have significantly positive correlations (p≤ .01) with all the variables, except right upper extremity length and right upper arm circumference. For rest of the anthropometric variables, it was observed that almost all the variables were correlated to each other significantly (p≤ .05 - .01) with positive correlations, except right upper extremity length and right upper arm circumference.

Background and Study Aim: Handgrip strength is widely used as a functionality parameter of the upper extremity and general health. The measurement of handgrip strength by dynamometry is a low cost, noninvasive method of simple applicability. The study aims to find out handgrip strength and its correlation with some anthropometric characteristics of the upper extremity and weightlifting performance of elite (international medalists) and sub-elite (national medalists) Olympic style weightlifting athletes. Material and Methods: We obtained anthropometric measurements of upper extremity of elite athletes (n=25 male, n= 20 female) and sub-elite athletes (n=25 male, n=29 female) in the study. Dominant and non-dominant handgrip strength measurements of the groups were obtained by a Jamar dynamometer, according to the recommendations of the American Association of Hand Therapists. Results:No statistically significant difference was observed in non-dominant handgrip strength of male elite and sub-elite weightlifting athletes. Similarly, no significant difference was observed in between some anthropometric characteristics of upper extremity and dominant and non-dominant handgrip strength of female elite and sub-elite weightlifting athletes. We didn’t find any asymmetry between dominant and non-dominant handgrip strength of study groups. We found a significant correlation between dominant and non-dominant handgrip strength of male and female elite athletes and their height, body weight, BMI and weightlifting performance. Conclusions: Consequently, we might explain that adding special exercises into the general trainings of athletes to develop handgrip strength might contribute to the weightlifting performance of the athletes.

Abstract Background: Protein-energy wasting (PEW) is a common complication of maintenance hemodialysis (MHD) patients. This study aimed to explore the PEW evaluation method in MHD patients. Methods: Clinical data, physical parameters, laboratory values, and a questionnaire survey of MHD patients were collected from PEW and non-PEW patients in our hospital from September to December 2019. Analysis of variance was used to assess the difference between the two groups. ROC analysis was used to compare the diagnostic efficacy of physical measurement and nutrition scores and find the appropriate evaluation criteria for clinical application. Results: 1. There were statistically significant differences in many physical parameters between the two groups (p<0.05). 2. ROC curve analysis showed that the diagnostic efficiency of a single physical measurement or nutritional score was not high, and multiple indexes should be combined. 3. The simplified Pew risk score formula was 27.4 + abdominal circumference + 0.4 * main handgrip strength - 3.2 * body mass index -1.9 * upper arm circumference, which had a sensitivity of 67.7% and specificity of 94.4% at AUC of 0.864 and cutoff of 0.043346. Conclusion: A combination of abdominal circumference, main handgrip strength, BMI, and upper arm circumference could comprehensively evaluate PEW to improve the diagnostic efficiency.

The present study examines the effect of animal-source-food (ASF) intake on arm muscle area growth as part of a larger study examining causal links between ASF intake, growth rate, physical activity, cognitive function and micronutrient status in Kenyan schoolchildren. This randomised, controlled feeding intervention study was designed with three isoenergetic feeding interventions of meat, milk, and plain traditional vegetable stew (githeri), and a control group receiving no snack. A total of twelve elementary schools were randomly assigned to interventions, with three schools per group, and two cohorts of 518 and 392 schoolchildren were enrolled 1 year apart. Children in each cohort were given feedings at school and studied for three school terms per year over 2 years, a total of 9 months per year: cohort I from 1998 to 2000 and cohort II from 1999 to 2001. Food intake was assessed by 24 h recall every 1–2 months and biochemical analysis for micronutrient status conducted annually (in cohort I only). Anthropometric measurements included height, weight, triceps skinfold (TSF) and mid-upper-arm circumference (MUAC). Mid-upper-arm muscle area (MAMA) and mid-upper-arm fat area (MAFA) were calculated. The two cohorts were combined for analyses. The meat group showed the steepest rates of gain in MUAC and MAMA over time, and the milk group showed the next largest significant MUAC and MAMA gain compared with the plain githeri and control groups (P< 0·05). The meat group showed the least increase in TSF and MAFA of all groups. These findings have implications for increasing micronutrient intake and lean body mass in primary schoolchildren consuming vegetarian diets.

Anthropometric Characteristics

The objective of the study was to predict of Libero’s performance on the basis of selected anthropometric characteristics. In this study, Libero’s performance was selected as dependent variable (DV) and selected anthropometric characteristics i.e. LP (Libero’s Performance), LH (Libero’s Height), LW (Libero’s Weight), LAL (Libero’s Arm Length), LFAL (Libero’s Fore Arm Length, LUAL (Libero’s Upper Arm Length), LUAC (Libero’s Upper Arm Circumference), LWC (Libero’s Waist Circumference), LHC (Libero’s Hip Circumference), LLL (Libero’s Leg Length), LLLL (Libero’s Lower Leg Length), LTC (Libero’s Thigh Circumference) and LCC (Libero’s Calf Circumference) were observed as independent variables (IV). For the purpose of the present study, the subjects were selected from Inter-university level Volleyball Tournament. A total of 75 male Liberos were purposively selected for the study. The age of the subjects ranged between 18-28 years. To find out relationship between Dependent Variable (Libero’s Performance) and Independent Variables (selected Anthropometric Characteristics), Product Moment correlation and multiple correlations were applied. For predicting Dependent Variable (Libero’s Performance) on the basis of Independent Variables (selected Anthropometric Characteristics), multiple regression equation was applied. Established regression models are: (1) Libero’s Performance = 114.163-551X Libero’s Height (2) Libero’s Performance = 137.345 -1.171 X Libero’s Height+.913 X Libero’s Leg Length (3) Libero’s Performance = 95.165 -.944 X Libero’s Height+1.296 X Libero’s Leg Length -1.024 X Libero’s Calf Circumference. The findings suggest that performance is associated with anthropometric characteristics with biomechanical implications that may be used to provide a more complete evaluation of Libero’s performance.

Abstract Background Studies on pediatric norms to be used for upper extremity post thrombotic syndrome (PTS) assessment have been conducted in North America, but these norms have never been evaluated in non-North American children. A validation study to assess the validity and reliability of the two currently available pediatric PTS assessment instruments, i.e. the Modified Villalta Score (MVS) and the Manco-Johnson Instrument (MJI), on a non-North American convenience sample of healthy children is necessary in order to account for differences that may exist across cultural boundaries. Aim To determine pediatric norms for upper extremity PTS assessment in a non-North American cohort and to determine normal discrepancies in arm circumference, which in American children have been found to be ≤1 cm in the MJI (1) and <3% in the MVS (2). In addition we aimed to evaluate the specificity of the upper extremity PTS assessment instruments by testing the hypothesis that healthy children receive a score of 0 (indicating absence of PTS) when using the pediatric PTS tools. Methods The study design was a community-based observational cross-sectional study using a cohort of 28 healthy children with no history of thrombosis, central venous catheter use and/or family history of thrombosis. Inter-rater reliability of the measurement instruments was assessed using two trained PTS examiners. Results Among the 28 healthy children, the median age was 6.6 years (range 1.5-12.8 years). The median (interquartile range, (IQR)) contra-lateral difference for mid-forearm circumference was 0.4 cm (0.3 cm); and for the mid-upper arm circumference was 0.3 cm (0.5 cm). The upper limit of normal for contra-lateral differences in upper limb circumference was 0.8 cm for mid-forearm and 1.0 cm for mid-upper arm. None of the children had greater than a 1 cm difference in mid-forearm or mid-upper arm circumference. Differences of greater than 3% were present in 4 children (14.3%) in the mid-upper arm circumference. In a simple linear regression model, the absolute difference in upper-arm circumference was positively associated with age (= -0.006 + 0.38 * age; R2=0.18, p=0.025). Agreement between two trained examiners for the healthy child cohort varied depending on the criteria used for determination of normal differences. Using a 1.0 cm cut-off for determination of normal differences resulted in 96% agreement between two trained examiners for both mid-upper arm and mid-forearm measurements. Use of a 3% difference as the cut-off resulted in a 93% agreement between the two examiners. There was 100% agreement for the remaining items of the PTS score. In addition to differences in arm circumference, three healthy children had signs and symptoms associated with PTS; one child (3.6%) presented with bilateral venous collaterals on the chest and shoulders and two children (7.1%) reported pain in the upper extremities, although the pain did not interfere with functioning. Conclusions In a sample of Israeli children, the use of an absolute cut-off measure for contra-lateral differences in upper limb circumference of >1.0 cm is a more applicable and reliable measurement than a 3% cut-off. The presence of signs and symptoms of PTS in the upper extremity of healthy children questions the specificity of the current available PTS assessment tools for upper extremity in children. 1.
