The paper deals with formal educational programmes for fencing coaches in Hungary, Great Britain and the Czech Republic. Based on a content analysis of mainly curricular documents, we were able to identify and describe similarities and differences in approaches to coach education. They were apparent primarily on the legislative, organisational and content level. The research shows that the road to coaching excellence takes a different length of time in different countries. It is even in sharp contrast to formal licence education of some fencing federations when it comes to a bachelor study programme. Differences were also found in the approach towards the organisation of practical training. The more traditionally designed education of coaches in Hungary and the Czech Republic differed from the education in Great Britain from a philosophical and content point of view, specifically in topics such as the application of soft skills and setting, planning and assessment of goals in coaches´ practice.
Most strength and conditioning coaches deal with the question in the training plan, how to supplement specific exercises, or which non-specific exercises would be the most suitable for achieving the set purpose. This study aims to assess what strength transfer with a focus on the lower limbs is projected from the selected strength intervention program (the right leg exercises only single-joint exercises: leg extension on machine and leg curl; the left leg exercises only multi-joint exercises: deadlift and leg press) to the force of the knee joint flexors and extensors during the eccentric and the concentric contraction. In one training session, the participants repeated every exercise five times in four series. The load intensity was around 90% of 1RM and was increased by 5% after the first and the fifth week. The rest interval was always three minutes long. For the left lower limb, the highest transfer (0.20) was from the leg press to the knee joint extensor at the eccentric contraction and from the deadlift was the highest transfer (0.19) to the knee joint extensor at the eccentric contraction. For the right lower limb, the highest transfer (0.53) was from the leg extension on a machine to the knee joint flexor at the concentric contraction and from the lying leg curl was the highest transfer (0.47) to the knee joint flexor at the concentric contraction.

The relationship between the muscular strength of hamstrings and quadriceps and their possible muscular imbalance is considered by many authors as one of the causes of knee joint injury. The aim of this work is to assess the exercise program including squat modifications both in terms of progression of lower limb strength and in terms of possible change of H: Q ratio. Probands were divided into five groups (one control, four experimental). The experimental groups practiced the intervention program twice a week for eight weeks (EX1: Barbell squat, EX2: Barbell half squat, EX3: Barbell half squat with countermovement). In one training session participants repeated the exercise five times in six series. All experimental groups exhibited significant differences in mean values (p < 0.01), indicating the progression of lower limb strength measured by 1RM for barbell squat. The differences in the mean values of the H: Q ratio measured on an isokinetic dynamometer in the isokinetic test mode at angular velocities of 60 and 300 degrees per second do not show statistically significant differences (p = 0.99338). The established strength intervention program is suitable for the development of lower limb strength and does not show any changes in the H: Q ratio.

Background: The highest prevalence of childhood obesity has been observed in developed countries. However, its prevalence is increasing in developing countries as well.Objectives: To evaluate demographic variation in the prevalence of obesity among 1361 children and adolescents of three Libyan cities Tripoli, Zawia, and Geryan (Tripoli– girls; n = 369, boys; n = 290, Zawia– girls; n = 250, boys; n = 89, and Geryan– girls; n = 230, boys; n = 133) aged 3–19 years.Methods: The study was carried out at Central Tripoli Pediatric Hospital during a year 2016/17.The researcher took the anthropometric measurements into the nurse’s room of the out-patient de-partment (OPD) and gave a questionnaire to children to be answered by one of the child’s parents. The question naire included questions related to the socioeconomic status, lifestyle (physical activity and eating habits) and family history of overweight and obesity.In this paper, a Chi-square test of independence is used to measures whether there is a relationship between gender and physical activity.The results show that there is a significant relationship between the physical activity and the gender for all three cities.
Weightlifting heavy load exercises are commonly used as a key instrument for enhancing performance if compared to those not using the exercise stimulating muscle tone. Studies examined the post-activation effect (PAP) using only one parameter but not in consecutive and intermingling exercises to prolongated the time of the PAP effect duration and maintain increased performance. Nine male students, with resistance training experience, performed warm-up and exercises enhancing muscle tone (EEMT) using squats to 90° flexion in the knee joint with 80 % 1 RM (repetition maximum) in 3 sets with 3 repetitions of squat in each set (2-3 min. rest intervals). After EEMT they performed a 10-m sprint test in 2nd and 5th min, the countermovement long jump (CLJ) test in the 5th and 6th minute, a 10-m sprint test in the 10th and 11th minute and the CLJ test in the 12th and 14th minute. The results showed that the average improvement was in 10-m sprint after EEMT 0,013 ± 0,05 seconds, but there were no statistical differences observed between the result without and with EEMT (p>0.05). We observed a significant improvement between jumps without and with EEMT in 5 – 14th min (p<0.05). There were no statistical differences between the results in CLJ carried out in 5-6th min after EEMT and after two 10-m sprints and the results carried out in 12-14th min. after EEMT, four 10-m sprints and two jumps (p>0.05). It was found that 10-m sprint has no negative effect on performance in the long jump and could be regularly applied to prolong the PAP effect.
