The Kinematics Of Taekwon-Do Back Kick, Jacek Wasik, Tomasz Gora
Baltic Journal of Health and Physical Activity
Background: The back kick (in taekwon-do terminology referred to as dwit chagi) is considered a powerful weapon in taekwon-do sparring. This paper attempts to identify the kinematic factors affecting the efficiency of the back kick on the basis of values obtained for foot and knee velocities and the duration of the kick. Material/Methods: The study was based on 3 taekwon-do athletes (aged 16.3 ±0.6 years; weight 66.0 ±7.9 kg; height 172.0 ±7.0 cm). The case study relied on an Italian system called Smart-D, manufactured by BTS S.p.A., used for complex movement analysis. Results: The mean resultant velocity of the dwit …

Reliability And Validity Of The International Physical Activity Questionnaire In Lithuania, Alvydas Kalvenas, Ionuţ Burlacu, Karim Abu-Omar
Baltic Journal of Health and Physical Activity
Background: Purpose of the study was to examine: (1) the criterion validity and test-retest reliability of the IPAQ-LT short-form (SF) and long-form (LF) and (2) its potential over-reporting and energy expenditure over-estimation. Material and methods: 130 participants, aged 18-69 years, wore the Actigraph GT3X accelerometer (ACC) on all waking hours over 7 consecutive days. One day before and after they completed both versions of the back-translated IPAQ-LT. 92 participants were included for the reliability and 81 for the validity tests. Spearman’s rho correlation coefficients were calculated as the measurement of agreement. Results: Only the walking category significantly (p <.05) correlated with the ACC, SF (.22), LF (.20). Compared with ACC data IPAQ-LT averaged 997% (SF) and 1512% (LF) more weekly minutes of PA and 864% (SF) and 1477% (LF) more MET-min/week. The classification of participants as sufficiently active was 87.6% (SF), 90.1% (LF), and 8.7% (ACC). Conclusions: The validity for total PA scored relatively low compared with other studies. Substantial PA over-reporting and EE over-estimation were observed. As such, the evidence is very weak to support the use of IPAQ-LT as a relative or an absolute measure of PA and further work in this regard is amended.
Pain Tolerance In Sport, Ewelina Salwin, Agnieszka Zajac
Pain Tolerance In Sport, Ewelina Salwin, Agnieszka Zajac
Baltic Journal of Health and Physical Activity
Pain is an inseparable element of the sports experience, regardless of the chosen discipline. The saying “no pain, no gain” perfectly describes the risk of an injury in sport as well as the expectations of high tolerance of pain. Sociologists note the connection between sport norms and values and the pain and behaviours related to an injury. While competing an athlete is under pressure of the coach, activists and supporters who expect him or her to continue and perform despite pain. However, pain in sport is not always a negative factor as it also plays an informative role indicating physical …

Analysis Of The Athlete Burnout Phenomenon: The Past, The Present And The Future Of Athlete Burnout Research, Alena Akhrem, Zuzanna Gazdowska
Analysis Of The Athlete Burnout Phenomenon: The Past, The Present And The Future Of Athlete Burnout Research, Alena Akhrem, Zuzanna Gazdowska
Baltic Journal of Health and Physical Activity
The paper describes traditional and alternative conceptualizations of athlete burnout, measurement instruments, the most recent studies investigating athlete burnout and potential prevention and intervention strategies. Athlete burnout, being an extremely aversive experiential state, is a serious problem for athletes and their coaches. It needs special treatment and discussion because of the severe consequences it leads to. Burned-out athletes are likely to withdraw from sport despite time, efforts and money they invested into it. However, the decision to leave sport usually does not relieve symptoms of burnout, but may also worsen athletes’ moral state. Therefore, it is not surprising that this …

Baltic Journal of Health and Physical Activity
Background: Among specific coordination abilities, kinesthetic differentiation capacity of movement belongs to the most crucial factors fostering rational human behavior in the surrounding environment. The capacity is universal – indispensable in nearly all sports disciplines. One of the most important constituent elements of kinesthetic differentiation is the so-called “force sense,” defined as differentiation of movement with respect to administering appropriate force. The authors of the study analyzed the correlation between the maximum force level in lower limbs and the accuracy of applying a targeted force value. Material/Methods: The study was conducted on 54 participants, students from the University School of …

Position Accuracy And Fix Rate Of Athletes In Location Monitoring, Cezary Specht, Tomasz Szot
Position Accuracy And Fix Rate Of Athletes In Location Monitoring, Cezary Specht, Tomasz Szot
Baltic Journal of Health and Physical Activity
Background: The two main factors determining the quality of motion monitoring are the accuracy of determination of position coordinates and the frequency of position logging (fix rate). Material and methods: A comparative analysis of contemporary photogrammetric, remote sensing and satellite methods shows a lack of uniform requirements in this respect with reference to the same sports. Considering the issue on an intuitive basis only, it seems obvious that the accuracy of position in 100-m sprint cannot be measured in metres, and the frequency of positioning should be sub-second. However, the precise values of these variables are not estimated. A mathematical …

Changes In Special Fitness Efficiency Of Ten-Year-Old Tennis Players In The Annual Training Cycle, Tomasz Waldzinski, Ewa Waldzinska
Baltic Journal of Health and Physical Activity
Background: The course of match actions is definitely gaining pace and dynamics because offensive and aggressive styles of the game are preferred. So there is no doubt that an appropriate level of competitors’ physical preparation has a fundamental meaning. The goal of the research was to determine changes in special fitness efficiency. Material/Methods: The research was based on a group of 16 tennis players aged 10 training tennis in the annual training cycle. In order to evaluate the level of special fitness efficiency, two tests reflecting physical fitness were used: “The game against the wall” and “The test of 100 …

Baltic Journal of Health and Physical Activity
Background: Exercise-induced stressors activate leukocyte HSPA1A and HSPB1 gene transcripts. However it is not clear how plyometric training affects the expression of these genes in basketball players under plyometric exercise. Therefore, the aim of this study was to investigate the changes in leukocyte HSPA1A and HSPB1 mRNA, in male basketball players after plyometric training. Material/Methods: Twelve male college basketball players (age 22.1 ±2.96 years) took part in this study. Peripheral blood (2.0 ml) was collected from the ulnar vein of each participant before and after a plyometric exercise to assess HSPA1A and HSPB1 mRNA relative expression of leukocyte via quantitative …
Physical Activity And Body Image Of Women: Literature Review, Sonia Mosur-Kaluza, Monika Guszkowska
Physical Activity And Body Image Of Women: Literature Review, Sonia Mosur-Kaluza, Monika Guszkowska
Baltic Journal of Health and Physical Activity
This study represents a review of literature on the relationship between recreational physical activity and the body image. This research encompasses 39 papers published between 2008 and 2015 that were available in the Academic Search Complete database. The results of comparative, prospective, and experimental research are ambiguous. These data suggest both a positive relationship between the body image and physical activity, i.e. a more positive body image among more active people and an improvement in the body image as a result of regular exercise, and a negative relationship, in particular, a more negative body image in persons engaging in “aesthetic” …
