.g., Hip flex , Hip ext , knee extensors and abductors have been found to be important during front kicking ( Busko, 2016 ; Jung et al., 2017 ), where different combat sport athletes showed similar peak Hip flex and Hip ext moment values ( Busko, 2016 ). Although the front kick primarily comprises fast muscle action, no study has focused on whether maximum, explosive or speed strength determines the IF peak in a front kick. This may be done by isokinetic measurement at different speeds and types of contraction ( Stastny et al., 2018 ), where low, medium and high

as well as the athlete’s body movements were studied through 3-dimentional kinematic analysis.
The study sample consisted of 14 female weightlifters ( Table 1 ) competing during the 2013 World Weightlifting Championships. All of the participants provided informed consent approved by the Józef Pilsudski University of Physical Education in Warsaw ethics committee. The official permissions for video recordings were provided by the Polish Weightlifting Federation and the International Weightlifting Federation. Twenty-eight attempts were analyzed (14

Academic Rigor and Dedication to Competitive Sport in Young People 12-18 Years: Major Social Issues
Quantitative study with the aim of linking the academic performance of students who are high-level athletes in Catalonia (Spain) and who do not have any institutional support (high-performance centre, reduction of subjects, etc.) or belong to any educational institution with adapted curriculum (90-95% of households), compared to sedentary students who play sports only occasionally.
The study divided students into two groups by age: 12, 14, 16 and 18 years old (secondary school). The general group (GG) was made up of students who did sports at school, did not participate in major competitions, and the weekly training requirement did not exceed 3 hours (N = 262). The group of athletes (AG) is made up of students who at least competed for the Championship of Catalonia (swimming and basketball) and the weekly training requirement exceeded 4.30 in younger students (N = 212). The questionnaires were constructed in order to gather academic information, highlighting the grades of the subjects for the second evaluation of the 2008-09 academic year and full-time sports data for training (day session, hours, competition) and schooling (public or private).
We found a significant correlation (0.99) in comparing the evolution of differences between the grades of the groups. Supporting an extraordinary demand for training, and increasing with age, student athletes have better academic performance throughout secondary education. However, this trend is broken in high school, coinciding with the highest dedication to training.
Two other important considerations are highlighted in the study: first, the GG presented inactivity levels which increase linearly with age and this is more prominent in females, and secondly, the enrolment of the school is basically AD private state-assisted and not public system, which can make us think about whether the family ideology also influences the sports options for children.

The Effects of Finish Sauna on Hemodynamics of the Circulatory System in Men and Women
Finnish sauna is one of the most popular among all the saunas types and as a result is the most commonly used. Bath in the Finnish sauna is a combination of heating with a warm and dry air and the short influence of high humidity and cooling with cold water and air. The article aims to identify pulse and blood pressure in the conditions of thermal heating in the sauna among women and men between the age of 20-25. Hypothetically sauna has a great influence on the basic hemodynamic parameters such as pulse and blood pressure. There were 127 healthy, young women and 74 men, students at the University of Physical Education in Wroclaw taking part in the experiment. Average age of the volunteers was 21.5 and 21.7.
The results indicate that a bath in the Finnish sauna leads to a significant increase of the pulse among men and women. Concurrently the results show a considerable decrease in diastolic pressure, with the systolic pressure remaining at almost the same level. It can be concluded that a bath in a Finnish sauna positively influences the hemodynamics of blood pressure and pulse. A series of bathes in the Finnish sauna leads to a considerable decrease of the systolic and diastolic pressure and an increase of the pulse among male and female volunteers.
