The Status

Gastrocnemius-soleus equinus (GSE) is a foot-ankle complaint in which the extensibility of the gastrocnemius (G) and soleus muscles (triceps surae) and ankle are limited to a dorsiflexion beyond a neutral ankle position. The asymmetric forces of leg muscles and the associated asymmetric loading forces might promote major activation of the triceps surae, tibialis anterior, transverses abdominal and multifidus muscles. Here, we made infrared recordings of 21 sportsmen (elite professional soccer players) before activity and after 30 min of running. These recordings were used to assess temperature modifications on the gastrocnemius, tibialis anterior, and Achilles tendon in GSE and non-GSE participants. We identified significant temperature modifications among GSE and non-GSE participants for the tibialis anterior muscle (mean, minimum, and maximum temperature values). The cutaneous temperature increased as a direct consequence of muscle activity in GSE participants. IR imaging capture was reliable to muscle pattern activation for lower limb. Based on our findings, we propose that non-invasive IR evaluation is suitable for clinical evaluation of the status of these muscles.

Athletic Development

Physical conditioning is crucial in building motion skills if the coach wants to ensure long-term athletic development. The essence is that physical conditioning needs to be developed before the development of technical skills of sports movements at a much higher intensity at each stage of the multi-annual training process. The adult competition system and training programs are being imposed on young athletes, so the essential motion skills are not being learned (Grāvītis @ Luika, 2015). The lack of physical conditioning in teenage years is very often reflected in the most inappropriate moments of an athlete's career, at the elite level. Insufficient physical conditioning is a reason for the instability of motion skills and injuries in extreme physical and psychological loads. The amount of physical activity can be measured as a step count. The aim of the research is to assess physical fitness rate for children practicing basketball, football or ice hockey with EUROFIT test battery. The study included boys, 100 basketball players, 100 soccer players and 100 ice hockey players from Latvia who were born in 2002 and started training in their sport during at the ages from 7 to 9, collected data of their conditioning for five years, divided into three age groups. According to EUROFIT tests, it was concluded that the ice hockey players have the highest physical conditioning rates according to EUROFIT standard from the athletes analyzed, and the basketball players have the lowest physical conditioning rates in EUROFIT tests from the athletes analyzed. We can conclude that the results of hockey players are higher than the scores of basketball and soccer players because ice hockey players practice more frequently, and dryland training is strictly organized, they develop all motor abilities that is needed for successive training in basic drills on ice.

Abstract The purpose of this study was twofold: (a) to profile physical characteristics and motor abilities of three age groups of soccer players - under 14 years, 14-17, and over 17, playing different positions - goalkeepers, defenders, midfielders, and forwards; and (b) to examine the inter-individual variability among the players in each age group in all physical and physiological measurements performed in the study. In addition, anthropometric, power, strength, and flexibility tests were administered. Findings showed large inter-individual variability in all three age groups and in all playing positions. Differences between playing positions were found only in the 14-17 group (body mass) and in the over-17 group (body height, body mass, fat-free mass, and mean power in the Wingate Anaerobic Test). Due to the observed large inter-individual variability, it was concluded that the findings obtained in the physical and physiological tests should be interpreted with caution when attempting to differentiate between successful and unsuccessful soccer players, as well as when trying to predict future success in soccer.

Motor abilities, including coordination abilities, represent fundamental prerequisite for future high performance in the field of physical education and sport. In primary school age the foundation is laid for further development of coordination abilities, as well as to acquire knowledge, skills and habits to practice coordination exercises. This 9-10 years old period is called the "golden age" in relation with the pace of development of these abilities.The aim of this research is to establish the actual status of the coordination abilities of the third grade pupils in Bulgaria and draw up a normative table for control and evaluation on its basis. 1073 children, at the age of 9 and 10 years, including 564 boys and 509 girls in third grade, from 13 Bulgarian primary schools have been tested, using the test battery of Hirtz et al. (1985): Тest 1: Backwards ball throw at a target; Test 2: Long jump test (1 м); Test 3: Orientation shuttle run test aiming at numbered targets. To evaluate the status of each of the indicators examined the so-called Six Sigma method was applied and a normative table for the coordination abilities was developed, respectively for boys and girls. The average level of the pupils who participated in the test responds to rating 4.0

The purpose of this study was to determine the underlying structure of the stretch-shortening cycle (SSC) jumping, acceleration and change-of-direction (COD) abilities in soccer players using principal component factor analysis (PCA). Based on the results of recent studies on male college athletes, we hypothesized that slow SSC jumping, acceleration and COD represent independent motor abilities in soccer players. Forty two soccer players (23.2±2.36 yr) performed three tests for each group of rapid lower-body movements: a) three vertical slow SSC jumping tests ‒ squat jump (SJ), countermovement jump (CMJ) and arm swing countermovement jump (CMJAS), b) three acceleration tests ‒ 5, 10 and 15 meter sprint times (ACC5, ACC10 and ACC15), and c) three COD tests ‒ modified agility test free (MATF), the 505 agility test (505) and 20 yard agility test (Y20). PCA was applied to establish the relationships among the factors (i.e. motor abilities) underlying the included manifest variables (i.e. performance tests). This procedure reduced all variables to a smaller number of independent latent dimensions. The results indicated three separate factors that may correspond to slow SSC jumping, acceleration and COD abilities. The magnitude of the correlation coefficients among the three motor abilities extracted was r<.56. Therefore, it is suggested that slow SSC jumping, acceleration and COD abilities represent independent motor abilities and consequently these should be trained and evaluated separately to assess soccer players’ physical profiles.

Kicking Performance

The present study made a dynamic analysis of the ground reaction forces developed on the supporting foot during instep kicking to investigate the relation between specific perceptual and motor abilities and the performance of this skill. 45 young soccer players (11–13 years of age) participated in a series of laboratory tests assessing simple, choice, and discrimination reaction time, sustained attention, depth perception, and sense of kinesthesis. Kicking performance measured by the amount of impulse (calculated as the integral of force) developed on the supporting foot during kicking. There was a significant correlation of the kicking impulse with choice reaction time ( r=−.54) and attention reaction time ( r=−.41). Stepwise regression analysis indicated that choice reaction time accounted for 29% of the variation in the anterior/posterior kicking impulse and 16.4% of the variation in the medio/lateral kicking impulse. The significant relation between kicking impulse and measures concerning speed of information processing suggests that processes associated with fast response selection may play an important role in instep-kicking performance. These findings can provide useful information for designing of training schemes and testing protocols.
