Both training and dietary practices used by athletes greatly vary. Current sports nutrition guidelines promote dietary manipulation of energy-yielding nutrients specific to the period of training. The study explores the ad libitum nutrition practices of four healthy adult recreational athletes during a 2-week cycling training camp (~100 km·d-1, ~240 min·d-1) with particular attention to the current sports nutrition recommendations. Based on evidence-based guidelines, peri-exercise carbohydrate (CHO) and protein (PRO) intake periodization cut-off levels were set for athletes. Training days were categorized as hard (HARD, two training units/day), middle (MID, one training unit/day), and easy (LOW, no training). Fourteen-day diet records were used and analyzed by nutritional software for energy intake (EI), carbohydrate (CHO), and protein (PRO) intake. Relative daily EI of 78.6±4.5, 73.3±6.4, 75.4±8.2 kcal·kg·d-1, and CHO 8.9±0.8, 7.8±1.0, 8.2±1.5 g·kg1 intakes were not different in HARD, MID and LOW days, respectively. The mean daily EI was 1.3× higher than the predicted total daily energy expenditure, irrespective of the training day category, resulting in ~500 kcal·d-1 energy surplus. In the 2h post-exercise period, PRO intake exceeded the current recommendations 4.6-fold, and CHO intake was significantly lower after a second training session on HARD days (0.7 g·kg·h-1) than a recommendation (1.2 g·kg·h-1). Mean in-exercise CHO intake (~11.5 g·h-1) was significantly under the moderate 30 g·h-1 recommendation. In conclusion, the dietary behaviours of recreational athletes are not consistent with current sports nutrition periodization guidelines. Energy intake throughout the training camp led to positive energy balance being highest on non-training days. Daily or during and post-exercise CHO and PRO intakes were not adjusted to the training sessions' volume, intensity, or duration.

Purpose: According to studies, the increased risk of obesity in today's general population is mainly caused by insufficient physical activity. In this study, we compared the effect of two types of endurance training. High-intensity interval training (HIIT) and aerobic (continuous) load training and their impact on selected aspects of body composition. Methods: This study included women (n = 14; 32 years old; height 166.3cm; weight 62.5kg) divided into two groups of seven participants. The tested groups were selected by a deliberate selection of 7 probands, training thrice a week for ten weeks. An entrance and exit examination was conducted using non-invasive techniques (anthropometric measurements, body composition analysis – bioimpedance analysis). A paired T-test (p < 0.05) was used for parameter analysis. Cohen's d was used to assess material significance. Results: Despite the small sample of tested women, better results were achieved in the group implementing the high-intensity interval training. However, these data do not allow for assessing a statistically significant difference between the two types of training methods in reducing the percentage of body fat. Changes in monitored parameters were thus evaluated as statistically insignificant. Conclusion: Despite the relevant results, better results were achieved in the HIIT intervention program. The limiting factors of the study were a small research sample with a deliberate selection and insufficient possibility to control eating habits. Furthermore, it is necessary to pay attention to the higher readiness and motivation of the participants. High-intensity interval training, thanks to its variability and low time requirement, proved to be a suitable exercise program for changing body composition not only in people with obesity but also in the adult population in general.

PURPOSE To examine the characteristics of menstrual cycles in female athletes in different sports, comparison of possible deviations and changes associated with new generations of female athletes in training processes. METHODS The research included a total of 143 respondents (average age 17.46 ± 2.61; average training experience 8.67 ± 3.85) who were divided into three groups: sports games (n=59), martial arts (n= 16) and aesthetic sports (n= 68). An anonymous survey specially prepared for the needs of this research was conducted among the respondents. The results were processed in the IBM SPSS program, v.26. Comparisons by sports categories were made using the Chi-square test for categorical variables and Kruskal-Walis analysis of variance for ordinal variables. In the case of significant differences obtained by Kruskal - Wallis analysis, the Dunn-Bonferroni post hoc test was performed to determine between which groups there is a difference. A logistic regression analysis was performed to predict the regularity of the menstrual cycle using age, length and duration of training and sport category. RESULTS The groups of sports do not differ from each other with regard to cycle regularity (p=0.088). There are no differences between sports groups (p=0.935) in cycle changes. There is also no difference in duration (p=0.883) and abundance of bleeding (p=0.700). A slightly higher irregularity of menstrual cycles was observed in the martial sports group. CONCLUSION The examined characteristics of the menstrual cycle of the new generation of female athletes according to the sports groups in this research did not show significant changes, but they were noticeable in the martial sports group. Although there is a common difference in the training duration of individual sports groups, future research and monitoring of the menstrual cycle in female athletes should be further reduced according to the possible effects on the reproductive and general health of female athletes.

Purpose: Video materials have been used as teaching tools for many years. With the development of modern technology, new video devices have appeared that have greatly improved the quality and capabilities of video materials. This study was conducted with the purpose of investigating and comparing the current traditional and modern ways of recording ski elements. In the traditional way of recording, the cameraman stands on the ski slope and uses a camera to record a demonstration of the ski element of the skier moving toward him. On the other hand, the modern way of recording was made with the Gopro 360 max, which allows you to record video while skiing. Methods: The sample of respondents who evaluated the quality of the traditional and the Gopro 360 max videos for three skiing elements consisted of 149 students (105 male and 44 female) from the Faculty of Kinesiology Osijek. Prior to the video quality assessment test, the performance of the ski elements was explained to the students using traditional and modern video footage. When solving the ski knowledge test, students had the opportunity to watch and use traditional and/or modern videos. Results: The average score that students achieved on the ski knowledge test was 8.9 ± 2.48 points (74.16 ± 0.21%). When evaluating the quality and contribution of the videos, students rated the usefulness of the traditional method of video recording with an average score of 3.01 ± 1.25, while the modern method of video recording received an average usefulness score of 3.79 ± 1.07. The difference between the traditional and modern video recording was statistically significant at the p < 0.01 level. Conclusion: The obtained results indicate that the way the Gopro360 max records and presents the skiing elements contributes significantly to the quality of the presentation and the acquisition of specific skiing knowledge compared to the traditional recording method.

Objective: The purpose of the study is to compare the effect of ten-week lasting whole-body electromyostimulation (WB-EMS) and the circuit resistance training programme (RT) on body composition and strength parameters in women at risk of sarcopenia. Methods: The WB-EMS programme was carried out once a week and included ten exercise sessions, the RT was carried out twice a week and included 20 sessions. 17 elderly women participated in the study, nine in a WB-EMS intervention group (age: 63.11±1.52 years; weight: 70.07±9.07kg; height: 165.11±6.4cm; BMI 25.81±3.96kg/m2), eight in a RT group (age: 62.13±1.69 years; weight: 73.58±3.87 kg; BMI 27.34±2.58 kg/m2). To assess body composition, dual-energy X-ray absorptiometry (DXA) was used. To determine the level of strength parameters, hand dynamometry and isokinetic dynamometry of knee flexors and knee extensors were used. Results: Body composition assessment was performed by dual-energy X-ray absorptiometry and strength parameters were evaluated using isometric dynamometry (knee flexors and extensors strength). After completing ten weeks of intervention, significant differences were observed for lean muscle mass (RT group, Leanmasspre-test 43316.91 ± 1856.77 vs. Leanmasspost-test 43939.56 ± 1869.84, p= 0.0307). No significant differences were found between the pre-test and post-test in the WB-EMS group (Leanmasspre-test 39472.56 ± 3370.04 vs. Leanmasspost-test 38835.56 ± 3306.84, p= 0.5995). The isokinetic dynamometry analysis showed significant differences for the extensors and the peak torque on the right side in the RT group (Extensors Peak Torquepre-test 98.00 ± 13.55 vs. Extensors Peak Torquepost-test 38835.56 ± 3306.84, p= 0.0160; Flexors Peak Torquepre-test 54.25 ± 11.14 vs. Flexors Peak Torquepost-test 59.75 ± 11.13, p= 0.0059). Conclusions: The most obvious finding that emerges from this study is that resistance training has shown a greater effect than whole-body electromyostimulation.

Introduction There is a lack of longitudinal research in the field of social behavior in children with intellectual disability (ID). The first goal of the research was to find out and compare the social behavior of children who regularly participating in Special Olympics (SO) competitions with non-sporty children. The second goal was to show the trend in the development of children's social behavior and to find out whether summer holidays have any effect on children's behavior. Methods The Reiss Screen Behavior questionnaire was used to determine social behavior. Participants were children with ID aged 6 - 20 years. A total of 4 measurements were performed over a two year period (the number of SO participants was n = 14, n = 18, n = 18, n = 13 and the number of non-sporty children was n = 42, n = 40, n = 39, n = 40). Results Participants in SO have better social behavior by up to 16 % compared to non-sporty children. The trend of development in social behavior is unbalanced among SO participants, and summer holidays cause improvements in their behavior. Non-sporty children have a convex trend in social behavior and summer holidays have no effect on their behavior. Conclusion In SO participants, social behavior differs by 0-9 % from the norm of ideal social behavior. In non-sporty children, social behavior differs by 5-25 % from the norm. Overall, the behavior of children with ID is very good, as it differs very little from the norm of ideal social behavior. In the Czech Republic, children with ID (participants in SO and non-sporty children) have much better social behavior than children with ID abroad.
在智力障碍儿童社会行为的纵向研究方面还比较缺乏。该研究的第一个目标是找出并比较经常参加特奥会(SO)比赛的儿童与不参加运动的儿童的社会行为。第二个目标是展示儿童社会行为的发展趋势，了解暑假对儿童的行为是否有影响。方法采用Reiss筛查行为问卷对社会行为进行调查。参与者为6 - 20岁的ID儿童。在两年的时间里，共进行了4次测量(SO参与者的数量为n = 14, n = 18, n = 18, n = 13，非运动儿童的数量为n = 42, n = 40, n = 39, n = 40)。结果参加体育运动的儿童的社会行为比不参加体育运动的儿童好16%。大学生社会行为发展趋势不平衡，暑假使大学生社会行为有所改善。非运动儿童的社会行为呈凸形趋势，暑假对其社会行为没有影响。结论SO被试的社会行为与理想社会行为规范相差0- 9%。在不喜欢运动的儿童中，社会行为与正常情况相差5- 25%。总的来说，本我儿童的行为是非常好的，因为它与理想的社会行为标准相差很小。在捷克共和国，有ID的儿童(参加SO和不运动的儿童)的社会行为要比国外有ID的儿童好得多。

Purpose: The current trend is an increasing sedentary lifestyle in all age categories. Among university students, there is an alarming decline in physical activity while increasing the percentage of total body fat compared to high school students. The main goal of the study is to describe the current state of body composition of university students and to assess the impact of physical activity/inactivity in this specific age group, which has changed very dynamically in recent years due to the coronavirus pandemic. Methods: A total of 358 probands with a mean age of 20.87 ± 1.43 years were involved in the research, of which 234 women (65.4%) had a height of 167.9 ± 6.3 cm and a body weight of 61.3 ± 10.0 kg, BMI 21.7 ± 3.2, body fat 25.9 ± 6.4%, skeletal muscle mass 24.7 ± 3.3% and 124 men (34.6%) with body height 180.9 ± 7.7 cm, body weight 77.6 ± 12.4 kg, BMI 23.6 ± 2.8, body fat 15.8 ± 5.4%, skeletal muscle mass 37.0 ± 5.6%. For the purposes of valid categorization into high active, minimally active, and inactive probands, the International Standardized Physical Activity Questionnaire (IPAQ) was used, which monitors physical activity in the last 7 days. The questionnaire includes questions regarding the frequency and time spent in each intensity of physical activity, as well as the time spent sitting. The non-invasive method of bioelectric tetrapolar impedance using the InBody 230 device was used for the analysis of somatic parameters. The Takei hand dynamometer was used for the diagnosis of muscle strength. Some selected results: According to IPAQ, probands were classified as inactive (16%), minimally active (58%) and high active (25%). The analysis of selected aspects of physical activity shows that men are more active than women, but both sexes spend more than 5.5 hours a day sitting on average. A total of 39% of probands have a higher level of total body fat than the recommended norms. Conclusion: The study showed that lower levels of physical activity are associated with higher values of total body fat in university students. At the same time, within our sample both sexes out of 84% comply with general recommendations regarding the volume and intensity of physical activity.

Among university students, there is an alarming decline in physical activity while increasing the percentage of total body fat compared to high school students. The main goal of the study is to describe the current state of body composition of university students and to assess the impact of physical activity/inactivity in this specific age group, which has changed very dynamically in recent years due to the coronavirus pandemic. Methods: A total of 358 probands with a mean age of 20.87 ± 1.43 years were involved in the research, of which 234 women (65.4%) had a height of 167.9 ± 6.3 cm and a body weight of 61.3 ± 10.0 kg, BMI 21.7 ± 3.2, body fat 25.9 ± 6.4%, skeletal muscle mass 24.7 ± 3.3% and 124 men (34.6%) with body height 180.9 ± 7.7 cm, body weight 77.6 ± 12.4 kg, BMI 23.6 ± 2.8, body fat 15.8 ± 5.4%, skeletal muscle mass 37.0 ± 5.6%. For the purposes of valid categorization into high active, minimally active, and inactive probands, the International Standardized Physical Activity Questionnaire (IPAQ) was used, which monitors physical activity in the last 7 days. The questionnaire includes questions regarding the frequency and time spent in each intensity of physical activity, as well as the time spent sitting. The non-invasive method of bioelectric tetrapolar impedance using the InBody 230 device was used for the analysis of somatic parameters. The Takei hand dynamometer was used for the diagnosis of muscle strength. Some selected results: According to IPAQ, probands were classified as inactive (16%), minimally active (58%) and high active (25%). The analysis of selected aspects of physical activity shows that men are more active than women, but both sexes spend more than 5.5 hours a day sitting on average. A total of 39% of probands have a higher level of total body fat than the recommended norms. Conclusion: The study showed that lower levels of physical activity are associated with higher values of total body fat in university students.

ABSTRACT Objective: This study aimed to investigate the effect of whole-body electromyostimulation (WB-EMS) and resistance training (RT) on the level of functional fitness in a group of elderly women. Participants: 63 women (60-65 years) were randomly divided into 2 experimental groups (19 in WB-EMS, 22 in RT) and one control group (22 women). Both experimental groups underwent a ten-week lasting interventional program, the control group was asked to maintain their usual daily regimen and lifestyle. Methods: Senior fitness test battery (SFT) determined the level of functional fitness in participants, and the dual-energy X-ray absorptiometry (DXA) assessed the body composition. Results: The RT group reported a statistically significant difference between pre-and post-test in values of the Chair Stand test (p = 0.04), 8 Foot up and Go (p = 0.03), in the Back Scratch test left side (p = 0.02) and the Chair Sit and Reach test right side (p = 0.05). The WB-EMS interventional program had a positive statistically significant effect only the on level of flexibility of the lower limbs measured by the Chair Sit and Reach test left side (p = 0.05). Conclusions: The results of all individual components of functional fitness measured by SFT in both experimental groups (WB-EMS, RT) show an improving tendency. Comparing WB-EMS and RT groups, better results were confirmed in the RT group. Study limitations: Extending the length of intervention programs could have a more significant effect on the level of functional fitness in elderly women.

PURPOSE: Performance in boxing is a combination of strength, speed, and stability to create maximum impact. One of the types of punches commonly used in boxing is the straight punch. The magnitude of force exerted at the point of impact is influenced by a number of factors. Therefore, some biomechanical parameters can have greater effect than others during punch performance. Likewise, different technique modalities influence punch force. This study aims to determine differences between kinetic and kinematic parameters of punches performed with two different techniques (with and without weight shifting). METHODS: Overall, 20 straight punches were performed (10 for each observed technique) by a top-level female boxer (26.1 years old, height 170.3 cm, weight 63.2 kg). Afterwards, four kinematic variables (shoulder, upper arm, forearm, and hand velocities) were analyzed together with the position of center of mass (Xsens, Awinda). Also, overall foot pressure force of both feet (Novel pressure insoles) was analyzed for each technique, as well as the impact force of each punch (Punchsensor). Differences between the techniques were determined by MANOVA. RESULTS: Significant differences were found in foot pressure force and impact force, with higher values of punch force determined in the straight punch performance that includes weight shifting (p=0.00). Regarding kinematic parameters, there were significant differences in shoulder velocity, forearm velocity, and center of mass position (p=0.00). Upper arm and hand velocity variables did not differ significantly. This result indicates that different punch preparation can exhibit greater force and better performance. CONCLUSION: The understanding of movement pattern in punching could provide insightful instruction to coaches and boxers on how to generate powerful straight punches. The presented data objectively determined differences between two approaches in performing a straight punch which could help in correcting technical performance.

PURPOSE: Agility is described as a rapid whole-body movement with change of velocity or direction in response to the different stimuli. Scientific research identified two independent types of agility performances: pre-planned agility (CODS) and non-planned agility (RAG). CODS represent generic movement patterns. They can mimic the demands of a sport but all of the movements are pre-planned. In CODS there is no response to a stimulus like in RAG where movements are in response to cues such as the movements of the ball or actions of the opposition players. Literature review show lack of studies that assessed CODS and RAG in children, most probably due insufficiency in quality testing protocols. Hence, the purpose of this study was construction and validation of newly developed agility test that measures RAG performances in children. METHODS: For this purpose, the Blaze Pod system (BP) was used. Three lighting pods were mounted on three 50 cm cones in triangle formation with 4,5 meters distance between cones (TRGA). Results were collected via BP app. Four movement patterns were used to test RAG. Start and finish of the tests were conducted with the tap on BP pods. The sample comprised of 80 elementary school children (boys; n=39, age=14.88±0.36 yrs, height=174,3±7,46 cm, mass 67,86±16,78 kg, and girls; n=41, age=14.85±0.31 yrs, height=167.49±5.72 cm, mass=59.34±10.54 kg). Statistical analysis included calculation of normality of distribution, reliability coefficients, correlations and analysis of variance. RESULTS: Tests showed acceptable reliability with CA=0.58, ICC=0.32 for boys and CA=0.78, ICC=0.55 for girls. Inter-item correlations were higher in girls’ sample (r=0.49-0.64) than in boys (r=0.27-0.41). Also, test showed good sensitivity, normal data distribution and good homogeneity with no differences between items (boys; F=0.07, p=0.93; girls; F=0.13, p=0.88). Better reliability of TRAG test for girls is most probably caused by gender morphological differences. Namely, we observed greater standard deviations (SD) of height (BH) and mass (BM) in boys (boys; BH=7.37, BM=16.97; girls; BH=5.68, BM=9.7) and scientific research confirmed negative influence of BM and BH on reactive agility performance. CONCLUSION: Altogether, newly constructed TRGA test seems to be reliable instrument for measuring reactive agility in pubescent boys and girls.
