The aim of this research is to evaluate the change in the hand grip strength of the male arm wrestlers before and after a unit of exercise. The participants of the research consist of sportsmen (n=16) of Fırat University arm wrestling team in 18-25 age group.Within the scope of the research, all of the tests and measurements (age, length, body weight, sports age, hand grip strength) were carried out on the experimental group before they started training and the same tests were repeated just after the exercises. A unit of exercise program consisted of warm up, cool down, and 5 sets of weight lifting with 12 repetitions and intensity of 70% that were in that day’s plan and program applied by the trainer.While descriptive statistics were adopted in the statistical analysis, to identify the significance level between the hand grip strength before and after the exercise paired sample t-test analysis was used. The significance level was shown as α = 0.05 in the analyses. While the right hand grip strength of the sportsmen (n=16) was statistically significant at 51.1062 ± 1.69709 before and 49.0437 ± 1.71770 (p=0.000) after the exercise, the left hand grip strength was statistically significant at 46.9000 ± 1.16179 before and 45.8063 ± 1.30078 (p=0.000) after the exercise.In conclusion, it was observed that there is a statistically significant negative decline in the hand grip strength of the arm wrestling sportsmen after a unit of exercise and it can be said that it is because of the exhaustion expected after the exercise.

Background: The ratio of the lengths of the index and the ring finger (2D:4D ratio) is generally different between men and women. This has often been used as an indicator of the levels of prenatal androgen exposure. It has hence been suggested to have a role in many gender differences including performance in sports. Men generally outperform women in most physical abilities. However, reports in various studies have been inconclusive, depending upon the physical ability tested. Hand Grip Strength (HGS) is a good measure of overall strength of an individual. Hence, we decided to determine the relationship between 2D:4D and HGS of both hands in men and women.Methods: Scanned images of both hands of young volunteers were analysed and the 2D:4D ratio calculated. HGS was measured and results correlated with 2D:4D.Results: 2D:4D ratio of men was significantly less than of women for the right (p<0.001) and the left hand (p<0.001). HGS of men was significantly greater than that of women for the right (p<0.0001) and for the left hand (p<0.0001). 2D:4D ratio in men showed a weak but significant positive correlation with HGS of right(p<0.05) and left hand(p<0.05). A weak but significant positive correlation was also seen for the left hand in females. However, 2D:4D ratios did not show any significant correlation with HGS for the right hand in women.Conclusions: We conclude that 2D:4D ratio is a measure of Hand Grip Strength in men, but is not a robust measure of HGS in women.

Abstract Based on adult inactivity, a new intervention named AgingPLUS was created, targeting motivational barriers to physical activity. Data come from a pilot study (N = 116), with 56 participants randomized to the AgingPLUS group (Mage = 63.52 years, SD = 7.89 years), and 60 randomized to the active control group (Mage = 63.06 years, SD = 8.30 years). Multi-group linear growth curve analyses examined improvements in hand-grip strength and blood pressure from pretest (Week 0) to immediate (Week 4) and delayed posttest (Week 8). Findings showed that only participants in the AgingPLUS group had significant improvements in hand-grip strength for the right (B = 1.34, p &lt; .001) and left hand (B = 1.73, p &lt; .001), as well as significant reductions in systolic (B = -3.28, p &lt; .05) and diastolic blood pressure (B = -1.92, p &lt; .01). These findings provide support for the efficacy of AgingPLUS.

Summary Study aim: the aim of this study was to assess the relationship between classical sport massage of the hand and the forearm and the surface temperature of upper limb muscles, and between hand grip strength and the range of motion in the radiocarpal joint. Material and methods: study participants comprised 35 women not engaging in competitive sport, aged 19–23 years. Thermal images were taken with a Flir A325 camera. Hand grip strength was measured using an analogue dynamometer. The range of motion in the radiocarpal joint was measured using a goniometer. All tests and measurements were performed twice: directly before and after the massage of the hand and the forearm (of the right limb). Classical massage was applied on the dorsal and palmar surfaces of the hand and on the anterior and posterior surfaces of the forearm. Results: after the massage, the temperature of the right limb increased significantly, as did the temperature of the posterior surface of the left limb. However, no change in temperature was observed on the anterior surfaces of the left forearm and the left arm. A significant increase in the range of motion in the right radiocarpal joint (in all planes) was observed. No significant differences in hand grip strength measured with a dynamometer were found before and after the massage. Conclusions: while classical sport massage increases muscle temperature, it does not improve effort capacity, and therefore it is not a sufficient means of preparing an athlete for physical effort. The massage increased the range of motion in the massaged limb, which mostly indicates the relaxing effect of the treatment.

Research on the acute physiological response to a padel match is limited. The present study aimed to: (a) evaluate neuromuscular, urinary, and hematological responses after simulated padel competition (SC) and (b) analyze possible gender differences. In this study, 28 high-level padel players participated (men = 13, age = 26.83 ± 6.57 years; women = 15, age = 30.07 ± 4.36 years). The following parameters were analyzed before and after SC: neuromuscular (hand grip strength, squat jump (SJ), countermovement jump (CMJ), and Abalakov jump (ABK)), hematological (red blood cells, hemoglobin, and hematocrit), and urinary (pH, specific gravity, microalbuminuria, and red blood cells). Significant gender differences were found in neuromuscular and hematological responses, with men obtaining higher values (p < 0.05). For the SC influence, changes were noted in ABK and microalbuminuria (p < 0.05). The percentages of change in hand grip strength, SJ (height and watts), CMJ (height), and ABK (height) were higher for men than women (p < 0.05). SC negatively influenced the neuromuscular parameters to a greater extent in women. Our results could be related to gender differences in game actions, the temporal structure, and anthropometric and physiological characteristics. Game dynamics and a different organic response between male and female padel playing were confirmed.

Physical Attributes

Polo is an equestrian team sport consisting of four players per team, with level of play determined by cumulative player handicap (−2 to +10 goals), with a higher handicap denoting a better player. There is minimal literature investigating Polo players’ physical attributes, hence the understanding of the physical characteristics that may contribute to an improved handicap are unknown. This study sought to identify the relationship between pertinent strength measures (left and right hand grip strength; absolute and relative isometric mid-thigh pull) and reaction time in Polo handicap in 19 New Zealand Polo players, and ascertain whether handicap could be predicted by these measures. Correlation coefficients were expressed using R values, accompanying descriptors and 90% confidence intervals (C.I.). Variance explained was expressed via the R2 statistic, and statistical significance set at p < 0.05. Right hand grip strength, isometric mid-thigh pull values were found to significantly correlate to and explain variance within Polo player handicap (all moderate to large correlations; p < 0.05). Whereas left hand grip strength (R: 0.380; 90% C.I. −0.011 to 0.670) and reaction time (0.020; −0.372 to 0.406) were non-significant, moderate and trivial correlates and predictors of handicap respectively. Practically, these findings highlight the differing roles between rein and mallet hands of Polo players and emphasise the importance of a strong and stable platform when riding and striking the ball. Lack of association with reaction time may be explained in part by higher handicapped Polo players employing a more proactive approach to the game.

The index finger and the 4th finger ratio (2D:4D) is the indicator of the prenatal testosterone. The aim of this study is to investigate the relationship between 2D:4D, hand preference and hand grip strength in swimmers. A total of 80 elite swimmers, participated in the study. Height, body weight, body mass index (BMI), hand 2D:4D finger measurements and hand grip strength tests were performed for athletes. The hand preference was determined by the Oldfield questionnaire and it was evaluated according to the Geschwind score. The data were recorded in the SPSS 20 program and p<0.05 was considered as statistically significant. It was found that in both men and women, a negative correlation was found between right and left hand 2D:4D and both dominant (DHGS) and non-dominant hand grip strength (NDHGS) values. It was found that men had lower 2D:4D ratio than women. For both right and left handed, there was a statistically significant difference between the right and left hand 2D:4D ratios in both men and women (p<0.05) and the dominant hand (DH) 2D:4D ratios were found to be lower than non-dominant hand (NDH) 2D:4D ratios in both men and women (p<0.05)  It can be said that the 2D:4D ratios may be the effect of determining the hand preference, the grip strength and therefore the strength.

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.

AbstractBackgroundAlthough a significant amount of research has been conducted on handgrip strength and its association with anthropometric variables, very few researchers have focused on assessment of back strength and its relationship with anthropometric variables in cricketers.ObjectiveTo investigate the degree of correlation between handgrip strength and back strength in cricket players of different maturity levels and to find the correlations of handgrip strength and back strength with anthropometric variables of age, height, body weight and body mass index (BMI).MethodsTwenty-four adolescents; aged 16.6 ± 0.8 years and 32 adult cricketers aged 24 ± 4.6 years were tested for height, body weight, BMI, hand grip strength and back strength. t values, Cohen’s d and Pearson’s correlation coefficients were calculated.ResultsHand grip strength and back strength were not found to correlate with each other at p ≤ 0.05 in adolescent players while a statistically significant large sized correlation was observed in adult cricketers at p = 0.001. Back strength and body weight were found to have a statistically significant moderate sized correlation with each other (r = 0.453 in the adolescent group and r = 0.355 in the adult group). Significant positive correlations were observed for left hand grip strength with height, body weight and BMI and also between back strength and age in the adult population of cricketers.ConclusionA significantly large correlation exists between handgrip strength and back strength in adult cricketers with no such correlation found for adolescent cricketers. Data of the present study justify its utility in the case of selection, assessment and rehabilitation of cricket players.

Cerebral proliferative angiopathy (CPA) is a rare clinical entity. This disorder is characterized by diffuse vascular abnormalities with intermingled normal brain parenchyma, and is differentiated from classic arteriovenous malformations. The management of CPA in patients presenting with nonhemorrhagic neurological deficits due to cerebral ischemia is challenging and controversial. The authors report a case of adult CPA with cerebral ischemia in which neurological deficits were improved after encephaloduroarteriosynangiosis (EDAS). A 28-year-old man presented with epilepsy. Magnetic resonance imaging and angiography showed a diffuse vascular network (CPA) in the right hemisphere. Antiepileptic medications were administered. Four years after the initial onset of epilepsy, the patient's left-hand grip strength gradually decreased over the course of 1 year. The MRI studies showed no infarcts, but technetium-99m–labeled ethyl cysteinate dimer (99mTc-ECD) SPECT studies obtained with acetazolamide challenge demonstrated hypoperfusion and severely impaired cerebrovascular reactivity over the affected hemisphere. This suggested that the patient's neurological deficits were associated with cerebral ischemia. The authors performed EDAS for cerebral ischemia, and the patient's hand grip strength gradually improved after the operation. Follow-up angiography studies obtained 7 months after the operation showed profound neovascularization through the superficial temporal artery and the middle meningeal artery. A SPECT study showed slight improvement of hypoperfusion at the focal region around the right motor area, indicating clinical improvement from the operation. The authors conclude that EDAS may be a treatment option for CPA-related hypoperfusion.
