Effects of water immersion on the recovery of upper and lower body anaerobic power following a wrestling session

The aim of this study was to examine effects of cold-water immersion after exercise on powerresponses of wrestlers. Twenty elite male wrestlers were formed by similar age, height, weight and fitness parameters. The wrestling training session included a 60-minute of vigorous exercise. It consisted of warm-up exercises, standing technical and tactical exercises that mostly allocates arm and leg muscles. Vertical jump height, ropes climb height, and delayed onset of soreness was measured before, after, 24 h and 48 hors after the wrestling training. Cold-water immersion caused decrements in power loss at each follow-up time in comparison to a thermo neutral immersion.  It can be suggested that the longer time needed for power to return to normal levels after cold treatment and assessment of varied contraction types may present a more broad demonstration of muscle function and consequential capacity for dynamic exercise following exercise-induced muscle damage

Comparison of red blood profiles and oxygen transport capacity of elite and sub-elite wrestlers

This study aimed to compare the red blood profiles’ that are determinants of oxygen transports system, of elite wrestlers with sub-elite wrestlers. This study consists of a twenty-one elite wrestlers representing national team of Turkey who volunteered to participate in the study. Biochemical parameters were determined during transition period and the bloods were drawn in a resting state for each participant. A paired T tests was used to check the variations in hematological parameters. There are no significant differences between the groups except age. Elite wrestlers age was found to be significantly higher than sub elite wrestlers (p = 0.019 <0.005).  RBC, HGB, HCT, MCH, MCHC were within normal limits and also for athletes indicates a positive development and there were no significant differences between the groups. Training increases total hemoglobin mass by stimulating erythropoiesis, which increases the amount of O2 that can be carried by blood. regular screening of hematological variables is desirable as many athletes have values near or below the lower limit of the normal range

Vitamin K2 Needs an RDI Separate from Vitamin K1

Vitamin K and its essential role in coagulation (vitamin K [Koagulation]) have been well established and accepted the world over. Many countries have a Recommended Daily Intake (RDI) for vitamin K based on early research, and its necessary role in the activation of vitamin K-dependent coagulation proteins is known. In the past few decades, the role of vitamin K-dependent proteins in processes beyond coagulation has been discovered. Various isoforms of vitamin K have been identified, and vitamin K2 specifically has been highlighted for its long half-life and extrahepatic activity, whereas the dietary form vitamin K1 has a shorter half-life. In this review, we highlight the specific activity of vitamin K2 based upon proposed frameworks necessary for a bioactive substance to be recommended for an RDI. Vitamin K2 meets all these criteria and should be considered for a specific dietary recommendation intake

Assessment of the requisites of microbiology based infectious disease training under the pressure of consultation needs

<p>Abstract</p> <p>Background</p> <p>Training of infectious disease (ID) specialists is structured on classical clinical microbiology training in Turkey and ID specialists work as clinical microbiologists at the same time. Hence, this study aimed to determine the clinical skills and knowledge required by clinical microbiologists.</p> <p>Methods</p> <p>A cross-sectional study was carried out between June 1, 2010 and September 15, 2010 in 32 ID departments in Turkey. Only patients hospitalized and followed up in the ID departments between January-June 2010 who required consultation with other disciplines were included.</p> <p>Results</p> <p>A total of 605 patients undergoing 1343 consultations were included, with pulmonology, neurology, cardiology, gastroenterology, nephrology, dermatology, haematology, and endocrinology being the most frequent consultation specialties. The consultation patterns were quite similar and were not affected by either the nature of infections or the critical clinical status of ID patients.</p> <p>Conclusions</p> <p>The results of our study show that certain internal medicine subdisciplines such as pulmonology, neurology and dermatology appear to be the principal clinical requisites in the training of ID specialists, rather than internal medicine as a whole.</p

Effects of self-selected dehydration and meaningful rehydration on anaerobic power and heart rate recovery of elite wrestlers

[Purpose] This study aimed to verify the effects of self-directed weight loss on lower-and upper-body power, fatigue index, and heart rate recovery immediately before a meaningful competition (12 hours of recovery). In addition, this study tested the hypothesis that weight loss provides advantages in strength and power, as the relative power of the wrestlers is higher than that of opponents in the same weight class who do not reduce weight. [Subjects and Methods] Eleven well-trained wrestlers volunteered for the study. At baseline, their mean +/- SD age, body mass, and height were 20.45 +/- 2.69 years, 74.36 +/- 9.22 kg, and 177 +/- 5.71 cm, respectively. Repeated-measures one-way analysis of variance was performed to analyze differences. [Results] Rapid weight loss achieved by restriction of energy and fluid intake resulted in exercise-impaired decreases in peak power and increased fatigue index. Moreover, weight loss by dehydration negatively affected cardiovascular stability. [Conclusion] Most of the negative effects of rapid weight loss disappear after a 12-hour recovery period, and relative peak power increases after weight loss

Relationship among sprint performance body composition and aerobic power in collegiate people

This study was aimed to investigate relationship among aerobic power, 10 meters and 100 meters sprint running speed, vertical jump and physical properties of male and female adolescents who engaged in regular physical activity. This study consisted of a total of 877 adolescents including 725 male and 142 female. A 12 minutes run for aerobic power test, vertical jump for anaerobic power, 10 meters and 100 meter sprints, body height, body weight, skinfold measurements and body mass index (BMI) assessments were made respectively. Independent t-test analysis was performed for comparison between the male and female in all variables. To determine the relationship variables, the correlation coefficients were calculated. It was determined that 100 meters test was highly correlated than 10 meters speed tests, vertical jump score was more powerful indicator than anaerobic power, and the sum of seven skinfold was also more powerful indicator than BMI in determination of aerobic power in males. Aerobic power showed no significant correlation with body weight, body height, BMI, vertical jump score, anaerobic power and 10 meters sprint in females. The aerobic power increases with increasing the sprint distance. The vertical jump height, anaerobic power, 10 m sprint running speed, 100 m sprint running speed, body weight, BMI and the sum of 7 skinfolds measurement have more assocations of aerobic power in males while 100 m sprint running speed, and the sum of 7 skinfolds measurement were strongly correlated with aerobic power in females

P 13 Effects of a short term walking program on lung function of obese early adolescent boys

The aim of this study was to investigate the effect of a sort-term walking exercise on some lung function parameters (such as forced vital capacity (FVC) and maximal voluntary ventilation (MVV)) in obese children. Total of 23 subjects who have BMI (body mass index) > 25 kg/m2 and age ranged from 12 to 14 years participated in this study. Subjects were randomly divided into two groups as intervention (n = 12) and control group (n = 11). Anthropometric features of subjects were shown in Table 1. For this study, lung function parameters were measured by using a spirometer. In this research, throughout 6 weeks, participants followed a closely supervised walking program consisted of 45-min sessions five times in each week with an intensity of 60% of heart rate reserve. SPSS was used for statistical analyses (SPSS Inc., Chicago, IL). T tests were utilised to compare before and after the changes between groups. Table 2 shows that there were significant increases in FVC and maximum MVV (p 0.05). All in all, short-term walking program had a significant positive effect on FVC and MVV lung functions. This research was designed to specify the effect of walking on respiratory system. The result of this study indicated that a short-term moderate intensity walking exercise may enhance changes in obese children’s respiratory system
