Morphological structures of elite Karateka and their impact on technical and fighting efficiency

The aim of the study was to identify the morphological structures that determine achievement of top results in karate. The study included a sample of 85 karateka competing as senior category athletes within the Croatian Karate Society, aged 18-29 years. Sixteen morphological parameters were used; technical efficiency was assessed using 8 variables, i.e. evaluation of particular karate techniques, whereas fighting efficiency was estimated on the basis of results achieved at a number of contests. Factorial analysis of morphological space revealed the presence of four major factors: factor of muscle mass, followed by skeleton transverse dimensionality, factor of skeleton longitudinal dimensionality, factor of subcutaneous adipose tissue, and factor of shoulder width determining optimal trunk proportions (athlete type) in karateka. Regression analysis showed the isolated group of morphological factors to significantly determine both technical and fighting efficiency of karate athletes. Generally, skeleton longitudinality and muscle mass, followed by skeleton transverse dimensionality were found to exert favorable effects, and adipose tissue unfavorable effects according to both criteria. Also, each individual morphological factor influenced the performance of every karate technique applied. Adipose tissue had greatest unfavorable impact, whereas shoulder width and muscle mass had favorable impact on the performance of arm techniques (kicking). Considering performance of leg techniques, skeleton longitudinality had highest favorable impact, and adipose tissue greatest unfavorable impact. Of the techniques applied, combined karate kicks, i.e. jaku zuki-mawashi geri and kizame zuki-jaku zuki were found to be the best predictors of fighting efficiency.     

The impact of basic motor abilities on the specific motoricity performance in elite karateka

The aim of the study was to identify motor structures that determine high performance in karate. The study included a group of 85 karateka aged 18-29 years, competing as senior category athletes within the Croatian Karate Society. A battery of 22 motor tests (9 basic motoricity tests and 13 specific motoricity tests) were used. Factor analysis of the basic motor variables pointed to the existence of three significant factors: coordination, explosive strength and movement frequency; whereas factor analysis of the specific motoricity area indicated two significant factors, i.e., factor of technical efficiency and factor of specific agility. Canonical correlation analysis showed the isolated set of basic motor factors to significantly determine both technical efficiency and specific agility-mobility of the karateka, with a predominance of the explosive strength (force) factor, followed by the speed and coordination factors.     

Predictors of the desire/decision to quit smoking in a cohort of Croatian adult smokers followed for five years: the crohort study

This study provides an overview of the incidence of smoking, the socio-demographic characteristics of Croatian smokers during a five-year period and an assessment of predictors of the desire/decision to quit smoking. Analyses were performed separately for 2003 and 2008. A total of 3,229 subjects were included in the survey. There is a significant trend of a decreasing number of smokers in all age groups in 2008, compared to 2003. Almost half of the smokers included in the study expressed desire to quit smoking. Factors contributing significantly to decision to quit smoking were different in 2003 and 2008, except one. Concern about the harmful effects of tobacco smoking on health was a significant predictor in both models. Very worried respondents were more likely to decide to quit smoking (OR 17.6, 95% CI 9.41 to 33.17 vs. OR 12.54; 95% CI 6.0 to 26.2) than those who were not worried at all.     

Role of screening in detection of clinically localized prostate cancer

The aim of this study was to confirm the role of screening by determining the percentage of clinically localized prostate cancer (stage A and B) in patients with prostate cancer detected on screening and in those presenting to urologic clinic for the symptoms of urination impairment or ostalgia. During the study, 1,000 men aged > or = 50 from the community of Cepin and village of Josipovac near Osijek were examined. The subjects with elevated concentration of total prostate specific antigen and/or digital rectal examination suspect of carcinoma underwent transperineal biopsy of the prostate. Clinical staging was performed in patients with prostate cancer detected on screening, and data on clinical staging for prostate cancer patients treated during the 1996-1997 period were retrieved from patient files of the Department of Urology, University Hospital "Osijek". On screening, 28 (80%) patients with localized prostate cancer and seven (20%) patients with metastases were detected. In the group of patients examined on an outpatient basis for the signs and symptoms of prostatism, there were 30 (83.4%) patients with metastases and only six (16.6%) patients with localized prostate cancer. Study results indicated that an early diagnosis of prostate cancer could be made by use of noninvasive and inexpensive methods that cause no major discomfort to the patient. Accordingly, these results appear to strongly support such screening in men, if not in all those aged over 50, then at least in the otherwise healthy, 50-70 age group.     

Insights into a mummy: a paleoradiological analysis

The aim of the study was to analyze possible human skeletal remains within the wrappings of a mummy from the Archaeological Museum, Zagreb, Croatia through the use of the multidetector CT (MDCT) technology. Plain X-ray films and MDCT images of the mummy were taken in both frontal and lateral views. In a single volumetric acquisition of the whole body by MDCT 0.75 mm axial slices were obtained and combined with sagittal and coronal reformatting and three-dimensional (3D) reconstruction. Sex and age was assessed visually using standard anthropological methods. The results suggest that the mummy was of an adult female, most likely over 40 years of age at death. Pathologies observed included degenerative changes on the vertebral column and healed fractures of the lower right arm. Damage of the ethmoid bone at the roof of the nasal cavity was most likely caused by mortuary brain removal practice. Remnants of a resin and an unusual object were found inside the cranial cavity. An elongated metal object and additional three metal "belts" can be seen on the lower portion of the body. All internal organs were removed and thoracic and abdominal cavities were filled with various substances, most likely mud and pieces of linen cloth. Our results show that the MDCT is a very useful technique for assessing the human remains in archeological samples, especially in comparison to the use of plain film (X-ray), where important details are obscured and 3D imaging impossible.     

The impact of cognitive processors and conative regulators on specific motor abilities in boxers

The aim of the study was to analyze the relations of cognitive processors and conative regulators with specific motor abilities of elite boxers. Three sets of variables including 3 cognitive and 6 conative variables as predictors, and 6 specific motor (boxing) variables as criteria were used in a sample of 92 boxers. A series of regression analyses between the set of cognitive variables and particular criterion variables revealed a predominant impact of serial processor on specific motor abilities based primarily on specific speed (frequency of boxing technique performance). The series of regression analyses also showed a predominant negative impact of dysregulation of the organ function regulators from the set of conative variables on the manifestation of specific motor abilities in boxers. The data obtained in the study were used to develop an alternative model of the motor - cognitive - conative processes in boxing.     

Effect of olanzapine on disruptive behavior in institutionalized patients with severe intellectual disability--a case series

Considerable number of intellectual disabled people experience some form of disruptive behavior. Antipsychotics are the most common treatment for these behaviors. Numerous patients were efficiently treated with thioridazine, recently withdrawn. The authors describe a case series of "thioridazine responders" treated with olanzapine. Thirty three patients with severe intellectual disability were recruited. All patients were assessed for seven types of disruptive behavior on five point scale. Patients with severe behavior disturbances were included in treatment. The time points of assessment were at day 0, 30, 60 and 180. Twenty one patient accomplished inclusion criteria. A significant decrease occurred at day 30 for all types of behavior. Total score, self injurious behavior, compulsive and destructive behavior showed further decrease at day 60 and became stable until the end of study. Olanzapine appears to be efficacious in the treatment of disruptive behavior in the intellectually disabled and could be substitute for thioridazine treatment.     

First toll free helpline for smoking cessation--analysis of results after one year of operation

The aim of the study was to prove that there is a strong need among the smoking population for the antismoking telephone helpline, and to describe the structure and dynamics of calls to the Call-center. Basic data on socio-demographic characteristics, smoking habits, and reasons for calling the Center were collected during telephone conversations with smokers. The data were entered into previously prepared tables. Statistical analysis included 7,452 telephone calls; most calls were received from persons aged 26-45 years (34%), followed by 19-24 (24%) and 45-60 (19%) age groups. There was no statistically significant difference in the number of calls between men and women (54% vs. 46%, respectively). Most callers consumed on average 20 cigarettes per day. The most frequent reason for calling was to get on how to stop smoking, whereas seeking information on professional literature was the least frequent reason for calling among our respondents. Four-fifths of persons making a call to the Center started smoking when they were between 16 and 20 years of age. We can conclude that there was a need for this type of intervention due to its accessibility and potentially wide coverage of interested users.     

Average height of adolescents in the Dinaric Alps

This study contributes to an update of average heights among European populations. Our investigation covering 2705 boys and 2842 girls aged 17 years, shows that, contrary to the general belief, adolescents of the Dinaric Alps are, on average, the tallest in Europe. With an average height of 185,6 cm, they are taller than Dutch adolescents (184 cm on average). Above all, the density of very tall subjects appears to be characteristic of the Dinaric Alps, since 28% measure 190 cm or more in height, as opposed to only 20% in Holland and 1.5% in France. Although our information is not complete, adolescent girls in the Dinaric Alps, with an average height of 171 cm come a close second to girls in Holland.
