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.

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.

The Relationship

Introduction: This study investigated the relationship between physical fitness, anthropometric characteristics, visual acuity of athletes with visual impairments, and their right shot performance. Method: The participants of the study involved 34 male athletes with different visual acuities who participated in the 2015 Visually Impaired Schools Goalball Championship in Alanya, Turkey. The means of the participants’ age, body weight, height, and sport age were 14.95 ± 1.28 years, 52.06 ± 8.89 kilograms, 163.58 ± 10.39 centimeters, 02.39 ± 1.50 years, respectively. The participants’ physical fitness, body fat percentage, handgrip (right–left), and spine flexibility were measured. Upper and lower extremity lengths were obtained through anthropometric measurements, and the athletes’ right shot performance was calculated. To analyze the data, the Shapiro–Wilk test was used, and one-way analysis of variance and independent sample t-test were performed, because the data showed a normal distribution ( p = .106). In addition, multivariate regression model analysis was utilized to investigate the relationship between all parameters and the athletes’ right shot performance. Results: A significant difference was found among the groups’ right shot performance ( p = .03), specifically on behalf of the athletes with low vision. When the participants’ anthropometric features, physical fitness values, and their right shot performance were examined, a positive relationship was observed between their dominant (right) handgrip strength and right shot performance (stepwise method; p = .03, R2 = 0.14). However, no significant difference emerged between their anthropometric characteristics and right shot performance. Discussion: It is considered that visual acuity and upper extremity muscle strength are of vital importance in goalball. Implications for practitioners: Whereas the International Blind Sports Federation applies rules according to visual acuity to offer equal conditions for some areas of sport, in goalball such a rule does not exist. It is important to make a change in the regulations for competition groupings according to visual acuities in goalball like in other sports for individuals with visual impairments. More frequent workout oriented to upper extremity muscle strength during right shot performance is suggested in the training sessions.

The Effect of Hand Dimensions, Hand Shape and Some Anthropometric Characteristics on Handgrip Strength in Male Grip Athletes and Non-AthletesIt has been suggested that athletes with longer fingers and larger hand surfaces enjoy stronger grip power. Therefore, some researchers have examined a number of factors and anthropometric variables that explain this issue. To our knowledge, the data is scarce. Thus, the aim of this study was to investigate the effect of hand dimensions, hand shape and some anthropometric characteristics on handgrip strength in male grip athletes and non-athletes. 80 subjects aged between 19 and 29 participated in this study in two groups including: national and collegian grip athletes (n=40), and non-athletes (n=40). Body height and mass were measured to calculate body mass index. The shape of the dominant hand was drawn on a piece of paper with a thin marker so that finger spans, finger lengths, and perimeters of the hand could be measured. The hand shape was estimated as the ratio of the hand width to hand length. Handgrip strength was measured in the dominant and non-dominant hand using a standard dynamometer. Descriptive statistics were used for each variable and independent t test was used to analyze the differences between the two groups. The Pearson correlation coefficient test was used to evaluate the correlation between studied variables. Also, to predict important variables in handgrip strength, the linear trend was assessed using a linear regression analysis. There was a significant difference between the two groups in absolute handgrip strength (p<0.001) and handgrip/height ratio (p<0.001). The indices of body height, body mass, lean body mass and body fat content (p<0.001) were significantly greater in grip athletes. All hand variables except FS1-4 (p>0.05) were significantly different between the groups (p<0.001). After controlling body mass all hand anthropometric characteristics except thumb length (r=0.240, p=0.135), hand shape (r=-0.029, p=0.858), middle finger length (r=0.305, p=0.056) and forearm circumference (r=0.162, p=0.319) significantly correlated with handgrip strength in grip athletes, but not in non-athletes, except for forearm circumference (r=0.406, p=0.010). The results showed that handgrip strength and some of the hand dimensions may be different in athletes who have handgrip movements with an object or opponent in comparison to non-athletes. Also, there was a significant positive correlation between handgrip strength and most of the hand dimensions in grip athletes. Therefore, these can be used in talent identification in handgrip-related sports and in clinical settings as well.

The aim – to identify and analyze causes for reamputations in military personnel with limb amputations due to ATO in East Ukraine. Patients and methods. All military personnel of the AFU within ATO was eligible for the study with diagnosis of limb amputations in the period from 01.06.2014 to 30.06.2016, and which were treated in hospitals of the Ministry of Defense of Ukraine. Among 7091 patients with injuries, 152 patients with limb amputations were identified. Results and discussion. Out of 152 patients, 25 (16%) underwent limbs reamputation, whereas 127 (84%) patients underwent amputation once. Patients in the study groups did not differ in age. Amputation was performed on the upper limb in 41 (32%) in the group of patients with amputations, which is significantly higher as compared to 2 (8%) patients in the reamputation group (p = 0.014). Analyses the level of amputations of the upper extremity showed no difference in the parameters. In 23 (92%) patients in the group with reamputation amputation of the lower limbs were diagnosed significantly more often as compared to 86 (68%) patients in the amputation group (p = 0.014). Analyses of the level of amputation of the lower extremity revealed that almost 3 times more often amputation was performed at the level of the ankle in the group of patients with reputations - 8 (32%) patients, as compared to 15 (12%) patients in the amputation group (p = 0.03). However, linear regression did not show a significant difference of these parameters in reamputations. Amputation of one upper extremity in the reamputation group was diagnosed 7 times less frequent - 1(4%) patient less often than in the amputation group - 37(29%) patients (p = 0.005). Conclusions: The results of the study of the injured in a hybrid war indicate that reamputations are more often associated with amputations at the level of the upper limb, but are less often diagnosed in patients with amputation of the lower extremity. Reamputations are more often performed with trauma of one limb. Clinical features in patients injured in the ATO zone in the East Ukraine demonstrate the frequency and characteristics of re-arrests that are different from other armed conflicts.

Objective: The postpartum period is a critical stage that exposes the mother to unpleasant experiences, including changes in energy level. Implementing reflexology during this period, as a branch of complementary medicine, may be helpful in promoting healthcare, especially in the areas of maternal and child health. Methods: In total, 70 eligible women who referred to health centers in the south of Tehran City, Iran, affiliated to Tehran University of Medical Sciences participated in this quasi-experimental study. A written informed consent form was obtained from them before initiating the study. The mothers of the postpartum routine care control group and the reflexology group received a massage for 3 consecutive days for 30 minutes (15 minutes per leg). Both study groups completed energy-related items in the Visual Fatigue Questionnaire before as well as immediately and one week after the completion of the intervention. The collected data were analyzed by SPSS. Results: Demographic characteristics and the energy level before intervention were homogenous in both research groups. Immediately after the intervention, the Mean±SD energy scores in the control and reflexology groups were 34.55±2.84 and 33.7±4.33, respectively; thus the obtained data revealed no statistically significant difference between the study groups (P=0.02). One week after the intervention, the Mean±SD energy scores in the reflexology and control groups were 35.87±2.71 and 35.5±3.43), respectively; thus, there was no significant difference between the study groups in this regard (P=0.64). Conclusion: The presented massage intervention was not as effective as a non-invasive low-cost method on the postpartum energy level of the study participants.

This study aims to compare EuroFit test results of 11-17-year-old males and females in Kosovo. 742 students were included in the study. 347 females and 395 males were determined by random selection from the schools in urban and rural areas of all regions. Kosovo's general population rate (52% male 48% female) was considered when determining the proportion of male and female students. Anthropometric characteristics including height, weight, and Body Mass Index (BMI) of students and the motoric characteristics including the values obtained from the tests such as flamingo balance, plate tapping, sit and reach, standing broad jump, handgrip strength, sit-ups (30 sec), bent arm hang, 10x5m shuttle run and 20 m endurance were compared. As a result, there was no statistically significant difference between the anthropometric characteristics of male and female students in adolescence; however, it was observed that as the age increased, males became heavier and taller than females (p<0.05). In general, while there was no statistically significant difference between males and females in flamingo balance, plate tapping and sit and reach tests (p> 0.05), males were determined to be more successful than females in standing broad jump test, handgrip strength test, sit-ups (30 sec) and 20 m endurance tests (p<0.05). It is observed that students in Kosovo are more successful than the other countries regarding motoric tests such as the anthropometric characteristics, which are thought to be more related to genetics, and speed/agility of arms and legs. On the other hand, they are unsuccessful in comparison with other countries with regard to flexibility and endurance in tests which are thought to be influenced by factors such as lifestyle, nutrition, and training.

Background: The daily living activities are among the essential components of life and reflect an important aspect of functional independence in older adults. This study aimed to determine the effect of Group Movie Therapy (GMT) on the Activities of Daily Living (ADL) in older adults. Methods: A randomized clinical trial was conducted on 48 older adults referred to Urban Comprehensive Health Service Centers of Kashan City, Iran. The study subjects were enrolled by a convenience sampling method and were randomly assigned to the intervention (n=24) and control (n=24) groups. GMT was performed in 6 weekly sessions. The Lawton’s ADL Scale was used for data collection. The obtained data were analyzed by the Chi-Squared test, Fisher’s Exact test, and Independent Samples t-test using SPSS. Results: There was no significant difference in the mean scores of Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL) before the intervention between the study groups. A significant difference was found in the mean scores of IADL after the intervention between the study groups (P=0.001); however, there was no significant difference in the BADL values of the groups after the intervention. Conclusion: GMT is a non-invasive, low-cost, and non-risky way to improve the elderly’s autonomy in performing IADL. Thus, GMT is recommended as a method of behavior therapy.

Statistical Effects

The study aims to find out the incidence of the absence of palmaris longus tendon and to study the effects of the case on handgrip strength of athletes. We studied whether 190 athletes (male n= 80, mean age: 18.9� 2.2; female n= 110, mean age: 18.5� 1.2) included in our study had palmaris longus tendon or not. Then, the handgrip strength values of the athletes were obtained by using a Jamar dynamometer, according to the recommendations of the American Association of Hand Therapists. Total number of participants having no palmaris longus tendon was 59 (31.05%) and it was observed that 37(19.47%) of these individuals didn�t have the tendon in both hands. The number of participants with unilateral tendon absence was 22 (11.5%). The tendon was absent in right hand of 10 individuals (5.26%) and in left hand of 12 individuals (6.31%). After controlling age, height, body weight and body mass index variables of the groups, it was observed that the presence or the absence of palmaris longus tendon in both hands of male athletes didn�t cause any statistical effects on handgrip strength of the athletes. However, left handgrip strength of female athletes with palmaris longus tendon in left hand was found to be higher than left handgrip strength of female athletes with no palmaris longus tendon (p[.01). According to the findings of the study, we might state that the presence or the absence of palmaris longus tendon does not cause a significant effect on handgrip strength of both hands of male athletes (p].05) and that its presence causes a significant effect on left handgrip strength of female athletes (p[.01).

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.
