Opis:
W prezentowanej pracy dokonano porównania zawodników piłki siatkowej (n = 24) z siatkarzami plażowymi (n = 20), pod kątem osiąganych maksymalnych momentów sił mięśniowych, dla 10 zespołów mięśniowych. Badania przeprowadzono na specjalnych stanowiskach służących do pomiarów momentów sił w warunkach statyki. Badane grupy zawodników różniły się wysokością i masą ciała, jednak uzyskane wyniki pozwalają przypuszczać, iż zawodnicy obu dyscyplin charakteryzują się podobnymi wartościami względnej, maksymalnej siły mięśniowej i topografii momentów sił.
This study presents a comparison of volleyball (n = 24) and beach volleyball (n = 20) players, in terms of maximal muscle torques for 10 muscle groups. The measurements were taken on a specific mechanical stands that were designed and built for measuring muscle torques under isometric conditions. Body mass and body height differed in examined groups significantly; however obtained results suggest, that players of both disciplines rather have similar level of relative muscle strength and a strength distribution.

Opis:
Isometric muscle activation of single joint to volleyball players is critic on sport performance to produce potential muscle force, however isometric measurement limited in isokinetic muscle activity measurement of volleyball players. Indeed, hand dynamometers commonly use in various body isometric force. Professional volleyball players age 16.23 ± 0.59 yr, body mass 60.22 ± 4.64 kg, hight 1.69 ± 0.04 m participated to peak and average isometric force measurement over 8 week pre and post test. Accordingly, single joint muscle force production measurement of volleyball players tested on isometric muscle activation using a new hand dynamometer activforce 2. Isometric muscle activation tests consisted of 24 body region from upper and lower compartment. For this isometric muscle action test detected on peak force outcomes (SEM: 37.90; CV: 1.79) and average force outcomes (SEM: 33.62; CV: 1.84). The high isometric muscle action joint loading performing mechanical test application recommended on athletic population to using isometric potential high contraction model by strength training performance separately in-season and off-season measurement modeling. Conclusion, peak and average force production progressive isometric modeling of volleyball athletes worked to current sport–health condition. As out, conclusion must be advanced isometric force measurement proper work in sport-specific tasks. The proper isometric force must be repeat sport performance outcome in different sport modalities.

Opis:
Background: Massage is a common treatment in physiotherapy, often used as a prophylaxis or during recovery following a musculoskeletal contusion. One form of therapeutic massage is deep tissue massage (DTM), which has become more popular in recent years as a way of performing targeted work with the myofascial system. Aim of the study: The aim of the study was to examine the effectiveness of deep tissue massage on superficial back line flexibility (hip flexion and knee extension range of motion – ROM). Material and methods: Elite volleyball players (n=15), age: 22.8 ± 4.41 years; mass: 82.67 ± 6.99 kg; height: 1.96 ± 0.08 m) were recruited for this study. Deep tissue massage of the myofascial superficial back line was performed from the plantar fascia through the gastrocnemius and soleus muscles, the hamstrings to the ischial tuberosity (based on Myers, 2014). Hip flexion and knee extension ROM were measured at rest both before and after DTM. The Wilcoxon signed-rank test was used to compare pre and post values during the intervention. Results: Following deep tissue massage, there was significant improvement in superficial back line flexibility, demonstrated by an increase in hip flexion angle compared to pre-DTM values in both lower limbs. Right lower limb pre-DTM 1.86±0.66; post 2.79±0.43 (p<0.005), left lower limb pre-DTM 2.36±0.74; post 2.79±0.43 (p<0.028). There was also significant improvement in superficial back line flexibility demonstrated by an increase in knee extension angle post-DTM in both lower limbs. Right lower limb pre-DTM 69.79°±10.8; post 81.43°±6.06, left lower limb pre-DTM 73.07°±11.45, post 82.50°±8.39). Conclusions: Deep tissue massage increases the flexibility of the superficial back line and can be used as a form of increasing range of motion in the hips and knees.

Opis:
The purpose of this study was to investigate the relationship between somatotype, muscle torque, maximal power output and height of rise of the body mass centre measured in akimbo counter movement jump (ACMJ), counter movement jump (CMJ) and spike jump (SPJ), and power output measured in maximal cycle ergometer exercise bouts in female volleyball players. Fourteen players participated in the study. Somatotype was determined using the Heath–Carter method. Maximal muscle torque was measured under static conditions. Power output was measured in 5 maximal cycle ergometer exercise bouts, 10 s each, at increasing external loads equal to 2.5, 5.0, 7.5, 10.0 and 12.5% of body weight (BW). All jump trials (ACMJ, SPJ and CMJ) were performed on a force plate. The mean somatotype of volleyball players was: 4.9-3.5-2.5. The value of the sum of muscle torque of the left upper extremities was significantly correlated only with mesomorphic component. Mesomorphic and ectomorphic components correlated significantly with values of maximal power measured during ACMJ and CMJ. Power output measured in maximal cycle ergometer exercise bouts at increasing external loads equal to 2.5, 5.0 and 7.5% of BW was significantly correlated with endomorphy, mesomorphy and ectomorphy.

Opis:
The state of athletes’ muscles is not constant, but it differs depending on the stage of sports training, which is associated with different degrees of muscle fatigue. There is thus a need to find a non-invasive and simple method to assess muscle fatigue. The aim of the study was to determine the relationship between muscle fatigue due to physical effort and changes in skin temperature, measured using a thermographic camera. Methods: The study involved 12 volleyball players. The participants were to maintain 70% of peak torque in the joint for as long as possible. We measured peak torque and the time of maintaining 70% of its value (tlim) as well as continuously recording skin temperature and electromyographic (EMG) signals in the region of the belly of the rectus femoris. The measurements were taken twice: before and after a series of squats. Results: The study found that tlim decreased when isometric contraction was performed after physical effort. Pre- and post-exercise skin temperature did not differ significantly, however, the increase rates of temperature and the root mean square (RMS) of the EMG signals grew significantly. In most of the players, skin temperature also correlated with the RMS, median frequency (MDF), and mean frequency (MF) of the EMG signals. Conclusions: Measuring the time of maintaining submaximal torque during isometric contraction and the slope coefficient for the increase in temperature recorded using a thermographic camera can be a simple, cost-effective, and non-invasive method of assessing fatigue and efficiency decreases in the muscles in volleyball players.

Opis:
Background. The article concerns high level beach volleyball players’ actions and in particular the issues of evaluation. The main object of the analysis is the setting which seems to be an action that can increase the efficiency of the attack. It was assumed that setting skills are very important part of synergistic potential of players. Material and methods. In process of evaluation an original method of observation and a modern approach based on the evaluation criteria of players’ skills proposed by Panfil was used. The study was based on three criteria: correctness, diversity and flexibility. Research materials were the recordings of 12 men’s beach volleyball matches played during the top international tournaments of the 2011 and 2012 FIVB Beach Volleyball SWATCH World Tour. Results. We recorded the number of actions, average level of correctness, diversity and flexibility for each of the selected 20 players. Flexibility was determined by two indexes: dependent flexibility and independent flexibility. Conclusions. It is essential to provide important aspects of the game characteristics and prepare hints for the training process designed for top beach volleyball teams, based on the solutions used by the best teams in the world. Additionally, the paper discussed and verified new tools that expand the general criteria of players’ skills evaluation proposed by Panfil specifically to beach volleyball.

Opis:
Zawodnicy występujący w latach międzywojennych w polskiej lidze piłkarskiej byli bardzo wszechstronni i utalentowani, dlatego odnosili sukcesy sportowe także w innych dyscyplinach sportu. Celem pracy była ocena skali tego zjawiska. Masowy rozwój piłki nożnej w Polsce sprawił, że brakowało utalentowanych zawodników w zmaganiach obejmujących gry sportowe, lekkoatletykę czy sporty zimowe. Wysoka sprawność piłkarzy predystynowała ich do udziału w rywalizacji sekcji klubów sportowych, innych niż futbolowe. Przedstawiono szczegółowe wykazy piłkarzy, uczestników rozgrywek ligowych w latach 1927–1939, którzy zostali medalistami mistrzostw Polski w hokeju na lodzie, lekkoatletyce, koszykówce, siatkówce i piłce ręcznej. Ponadto zaprezentowano sylwetki i dokonania najbardziej wszechstronnych zawodników.
The players who played in the Polish football league in the interwar period were very versatile and talented, therefore they were also successful in other sports. The aim of the study was to assess the scale of this phenomenon. The mass development of football in Poland meant that there was a shortage of talented players in the struggle involving sports games, athletics or winter sports. The high level of physical fitness of the players predisposed them to participate in the competitions in sections of sports clubs other than football. The author presents detailed lists of footballers, participants in league competitions in the years 1927–1939, who became medallists of Polish championships in ice hockey, athletics, basketball, volleyball and handball. In addition, the biographies and achievements of the most versatile athletes are included.
