Objectives: The physical component of tasks can be a problem because of muscle weakness; therefore, this research was performed to investigate the relationships between some physical fitness factors and muscle damage enzyme levels in people with mild Intellectual Disabilities (ID). Methods: In this cross-sectional study, 314 students with ID (Body Mass Index [BMI]: 23.42±4.84 kg/m2), after measuring their anthropometric variables (height, weight, and BMI), performed the Canadian Standardized Test of Fitness (CSTF). This test includes flexibility (sit and reach test), muscle endurance (Push-ups and Sit-ups tests), muscle strength (Hand-grip test), and cardiorespiratory endurance (Canada Home Fitness test). Then saliva samples were collected from 20 subjects who were homogeneous for age (Mean±SD: 20.30±2.27 years), sex (male only), and type of ID, for measuring their saliva levels of Creatine Phosphate Kinase (CPK), Lactate Dehydrogenase (LDH), and C-reactive Protein (CRP). Data were analyzed by the Pearson correlation coefficient and linear and nonlinear regressions (P<0.05).  Results: The findings indicated significant relationships between some of the physical fitness factors and some enzymes of muscle damage (P<0.05). The results indicated significant relationships between CPK, with push-ups, sit-ups, and hand-grip strength, as well as between the LDH with push-ups and CRP with sit-ups and hand-grip strength (P<0.05). Discussion: According to the results of the present research, CPK, LDH, and CRP saliva levels in males with an ID have a significant relationship with some of the physical fitness components. Also, the results of the present research have provided equations for estimating CPK, LDH, and CRP saliva levels through CSTF battery test scores in people who have an educable ID.

Police officers may be required to use their firearms in self-defence. The purpose of this study was to evaluate the relationships between hand grip size and strength with pistol shooting accuracy in police officers. Twelve (age = 38.08 ± 6.24 years; height = 174.42 ± 7.33 cm) police officers had their hand sizes (palm width and hand span) and hand grip strength measured. Handgrip dynamometer was set at a Glock 17 pistol's grip width (50 mm). The officers fired 10 rounds from their service pistols at a stationary target. Independent samples t-tests were performed to identify differences between the sexes. Correlations were used to investigate relationships between measures of hand size, strength, and marksmanship. Alpha levels were set at p < 0.05. Male officers were significantly stronger (p = 0.01) and had a bigger hand width (p = 0.03), but not hand span. There were no significant differences in marksmanship between the sexes. Neither hand size nor grip strength had a significant impact on marksmanship even though there were strong and significant relationships between hand size (span and MCP) and grip strength. A V-shaped curve appears to exist between grip strength and marksmanship and hand span and marksmanship, with a potential influencing factor being the standard sizing of the pistol grip.

Objectives To determine whether age, body mass index (BMI), hand length and forearm circumference were predictive of hand grip strength in healthy Saudi Arabian adult males. Methods This cross-sectional descriptive study recruited healthy adult male volunteers. Their anthropometric characteristics including age, BMI, hand length and forearm circumference were measured using routine techniques. Hand grip strength was assessed using a Jamar® Hydraulic Hand Dynamometer. The data were analysed using Pearson correlation coefficient ( r) as well as by a stepwise multiple linear regression analysis. Results The study included 116 healthy males who satisfied the inclusion criteria. A Pearson correlation coefficient matrix demonstrated that all the four measures, age, BMI, hand length and forearm circumference, were significantly correlated with hand grip strength. Age had an inverse correlation with hand grip strength. The anthropometric measures of hand length, age and forearm circumference accounted for 44.2% (R2 0.442) of the variation of the hand grip strength. Conclusion Hand length, age and forearm circumference significantly impacted on hand grip strength in Saudi Arabian healthy adult males.

Introduction: An individual’s overall muscle strength is commonly assessed by a power grip measurement, a reliable indicator of functional capacity and physical condition. The development of muscle parallels the changes of body composition during growth. Aim of this study is to examine the correlationship between hand grip strength and anthropometric. Methods: This cross-sectional study involved 76 male students of Dhammasavana School, aged between 12 – 16 years old, North Jakarta. Hand grip strength was examined using a digital dynamometer on the dominant side. Statistical analysis was computed using SPSS ver. 15.0 program with Spearman correlations test. Significance was set at p<0.05. Results: Dominant hand grip strength was found to have significant (p<0.05 - 0.001) positive correlation with height (r=0.612), lower arm muscle-and-bone cross-sectional circumference and area (CSA) (r=0.553 and r=0.553 respectively), hand length (r=0.548), forearm length (r=0.540), age (r=0.520), weight (r=0.416), and forearm girth (r=0.376). Conclusion: No significant correlation between grip strength and body mass index was found. Positive correlations between the variables mentioned above conclude that the higher the value of the anthropometric measurements, the greater the strength generated in a power grip.

Abstract Introduction: Physical exercise is used as a strategy for the prevention of falls because it improves the physical fitness of older adults. Objective: To determine which components of physical fitness are predictors of falls in elderly female exercise practitioners. Method: Longitudinal, descriptive, comparative study. The components of physical fitness (upper and lower limb strength and flexibility, agility, aerobic endurance, and hand grip strength) and the occurrence or not of falls in the last 12 months were analyzed in 80 older women practitioners of exercise from 2013 to 2016. Descriptive analysis, ROC curve attributing cut-off points, and binary logistic regression for the prediction of falls were used. Results: The mean age of the participants was 67.46 years (SD=7.65). Over the years, a significant difference between elderly fallers and non-fallers was observed for right hand grip strength (2013 and 2015), left hand grip strength (2014 and 2015), lower limb flexibility (2013, 2014 and 2015), agility (2015), and aerobic endurance (2015). In adjusted analysis, older women with poor lower limb flexibility in 2013 had a higher risk of falls in 2016 (OR=4.98; 95%CI 1.12 - 22.1). Older women with poor flexibility in 2015 also had a higher risk of falls (OR= 6.08; 95%CI 1.06 - 34.67). Conclusion: Poor performance in the lower limb flexibility, right and left hand grip strength, agility and aerobic endurance tests was associated with falls and these components are predictors of future falls in elderly exercise practitioners.

The aim of this study was to analysis the anthropometry and fitness of the under-16 regional and school cricket players. Twenty participants were selected from the Bahawalpur regional cricket team and (n = 20) from school teams. Selected variables were height, weight, skinfolds, girths, bone lengths, breadths, 30-m race, set-ups, hand grip strength, flexibility, standing broad jump, and agility. the anthropometric and physical fitness of regional and school cricket players was compared by applying Independent t-test. The results disclosed that the regional cricket players were significantly higher in arm span, arm length, and leg lengths, shoulder, elbow and knee breadths. The regional cricketers were faster in 30 m sprints, hand grip strength, setups, flexibility, and standing broad jump than school players. It was concluded the under-16 regional players were superior in anthropometric and physical fitness because they were selected from the larger population and regular in training program than school cricketers.

Abstract Background Pregnancy results in many changes, including reduced hand grip strength (HGS). However, good HGS is required for physical functions such as carrying and breastfeeding the baby after birth. The aim of this study was to determine the factors that may predict HGS during pregnancy. Methods The study was a cross-sectional study approved by the Research Ethics Committees of Kano State Ministry of Health and Aminu Kano Teaching Hospital in Kano, north-west, Nigeria. Pregnant women at the designated hospitals were included in the study if they had no serious comorbidities or any known neurological condition that affects the hands and the neck. Demographic characteristics and independent (predictor) variables (age, weight, height, BMI, maternity leave status, number of full-term deliveries, number of preterm deliveries, number of live births, number of abortuses, gravidity, trimester, systolic blood pressure, diastolic blood pressure, inter arm systolic BP difference [IASBP], inter arm diastolic BP difference [IADBP], and heart rate) of each of the participants were recorded by experienced therapists. The data were analysed using descriptive statistics, t-test, Pearson correlation coefficient and standard multiple regression. Result One hundred and sixty-one pregnant women with mean age, 25.04 ± 4.83 years participated in the study. In the dominant hand, 120 participants (74.5%) had weak grip strength. In the non-dominant hand, 135 participants (83.9%) had weak grip strength. For the dominant hand, the total variance explained by the whole model was significant, 28.5%, F(11, 161) = 1.187, R2 = 0.081, p = 0.300 . In the final model, none of the variables significantly predicted HGS. However, systolic blood pressure contributed to the model more than any other variable (Beta = -0.155). For the non-dominant hand, the total variance explained by the whole model was not significant, 33.1%, F(11, 161) = 1.675, R2 = 0.111, p = 0.089 . In the final model, only systolic blood pressure (Beta = -0.254, p = 0.023) significantly predicted hand grip strength. Conclusion Cardiovascular events or changes during pregnancy (such as change in systolic blood pressure) may be related to HGS in pregnant women. It is therefore, important for clinicians to pay attention to this, in planning rehabilitation strategies for pregnant women.
