Gender Differences in Neuromuscular, Haematological and Urinary Responses during Padel Matches

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.

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.

AbstractThe aim of this paper is to determine inter-reliability, concurrent validity, and interchangeability of the SMS HG dynamometric system and a Jamar digital dynamometer for hand grip strength measurements performed in two relevant positions of the elbow joint, i.e. 90 ° flexion and 180 ° (full) extension. The sample in this research consisted of 61 participants and included 27 women and 34 men. Statistically significant differences in the results found between two positions in the elbow joint indicate that the results must be evaluated separately. However, regarding both testing positions, i.e. 90 ° flexion and 180 ° extension in the elbow joint, it was determined that SMS HG and Jamar instruments have a very high level of inter-reliability (ICC 0.948 to 0.980), but lack concurrent validity. The established mean difference of the results was higher for the 90 ° than for the 180 ° position but in both cases was considered to have a practical significance, thus not supporting the interchangeability of the instruments.

Objectives: Thumb metacarpophalangeal (MCP) joint injury is frequently seen due to dynamic character of handball game. Spica taping is generally applied to protect thumb during returning to sports activities following rehabilitation in handball player. The aim of this study was to investigate the effect of spica taping on grip strength and grip endurance in professional handball players. Methods: Thirteen female handball players who was playing in Turkey Handball Federation Super League participated in the study. Mean age was 25.23±5.47 years, mean age of beginning to sports was 13.15±5.62 years, mean body mass index was (BMI) 22.38±2.74 kg/cm2. Hand grip strength and grip endurance in dominant side were evaluated before and after spica taping. “Jamar Hand Dynamometer” was used to assess hand grip strength. Grip endurance was measured in seconds during half of average grip strength sustaining for each players. All assessments were applied while sitting during shoulder adduction and neutral rotation with 90° elbow flexion, forearm midrotation, and neutral wrist position. Measurements were repeated 3 times and average values were recorded. Results: There was a statistically significant difference in grip strength between before and after spica taping application (p<0.001). There was a statistically difference in grip endurance between before and after spica taping application (p<0.001). Conclusion: Our results demonstrated that thumb spica taping is effective in improving grip strength and grip endurance in handball players. We suggest that supporting thumb stabilization without limiting hand functions might protect the MCP joint, and contribute injury prevention accompanying with improving sports performance. Consequently, thumb taping is recommended to handball players before competition.

Research background and hypothesis. The specificity of the technical performance in judo demands from athletes to perform fast and powerful actions at a high level, therefore, much importance is given to the development of aerobic capacity and supporting motor system, in particular, strength of the hand-grip function. Research aim was to study the judoka’s hand-grip strength and lung vital capacity indices in the aspect of age and weight categories and find out the relation between those two factors as well as the most characteristic age period of motor development. Research methods. The studies were carried out in the preparatory periods of 2009–2011 training cycles. The subjects were 2000 male judokas in 8 different weight categories. The measurements were made using a dynamometer and dry spirometer. The obtained results were statistically processed by SPSS 19, using ANOVA test.Research results. Research results showed that the judoka’s hand-grip and lung vital capacity average indices increased in each higher age and weight category, but this increase was not regular. The most obvious period of motor development at which increase in results was most noticeable was 13–15 years of age. The increase in the hand-grip strength and lung vital capacity in the age and weight categories were inversely proportional, and we found a correlation between them. Discussion and conclusion. We suggest that there is a close relationship between motor system and the muscles participating in respiration.Keywords: hand grip, lung vital capacity, data dynamics, practical use.

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.
