Context: Tournament season can provoke overreaching syndrome in professional tennis players, which may lead to deteriorated performance. Thus, appropriate recovery methods are crucial for athletes in order to sustain high-level performance and avoid injuries. We hypothesized that whole-body cryostimulation could be applied to support the recovery process. Objective: To assess the effects of 5 days of whole-body cryostimulation combined with moderate-intensity training on immunologic, hormonal, and hematologic responses; resting metabolic rate; and tennis performance in a posttournament season. Design: Controlled laboratory study. Setting: National Olympic Sport Centre. Patients or Other Participants: Twelve high-ranking professional tennis players. Intervention(s): Participants followed a moderate-intensity training program. A subgroup was treated with the 5-day wholebody cryostimulation (-120°C) applied twice a day. The control subgroup participated in the training only. Main Outcome Measure(s): Pretreatment and posttreatment blood samples were collected and analyzed for tumor necrosis factor a, interleukin 6, testosterone, cortisol, and creatine kinase. Resting metabolic rate and performance of a tennis drill were also assessed. Results: Proinflammatory cytokine (tumor necrosis factor a) decreased and pleiotropic cytokine (interleukin 6) and cortisol increased in the group exposed to cryostimulation. In the same group, greater stroke effectiveness during the tennis drill and faster recovery were observed. Neither the training program nor cryostimulation affected resting metabolic rate. Conclusions: Professional tennis players experienced an intensified inflammatory response after the completed tournament season, which may lead to overreaching. Applying wholebody cryostimulation in conjunction with moderate-intensity training was more effective for the recovery process than the training itself. The 5-day exposure to cryostimulation twice a day ameliorated the cytokine profile, resulting in a decrease in tumor necrosis factor a and an increase in interleukin 6. © by the National Athletic Trainers' Association, Inc. 2012.


The study defines the idea behind the research project which analyzes the swing-through gait from the biomechanical and kinesiological perspective. In the preliminary phase, the authors performed a synthetic analysis of the state of knowledge, created a description of the general kinematic structure of the swing-through gait as a form of locomotion with the use of crutches, proposed definitions. The problem was described with the use of time characteristics of vertical and horizontal anterior-posterior as well as lateral components of ground reaction forces, measured from under the supporting limb and the crutches. Presenting the idea behind the research project, the authors defined in detail the purpose of the study, the assumptions, research methodology--including a description of methods used and the measurement channels which consisted of: 2 AMTI force platforms integrated into a measurement walkway, a set of 6 optoelectronic cameras of the BTS System as well as a multichannel kinesiologic electromyography performed with the use of the NORAXON System. All phases of the research were characterized, presenting the research protocol in its entirety. The research will be conducted in the Laboratory of the Department of Biomechanics of USPS in Poznan, which possesses the ISO 9001:2008 quality management system certificate.

The main aim of the present study was to examine to what extent long-lasting subcortical actions of transcranial direct current stimulation (tDCS) may be related to its presynaptic actions. This was investigated in the red nucleus, where tDCS was recently demonstrated to facilitate transmission between interpositorubral and rubrospinal neurons. Changes in the excitability of preterminal axonal branches of interpositorubral neurons close to rubrospinal neurons were investigated during and after tDCS (0.2 mA) applied over the sensorimotor cortical area in deeply anaesthetized rats and cats. As a measure of the excitability, we used the probability of antidromic activation of individual interpositorubral neurons by electrical stimuli applied in the red nucleus. Our second aim was to compare effects of weak (≤1 μA) direct current applied within the red nucleus with effects of tDCS to allow the use of local depolarization in a further analysis of mechanisms of tDCS instead of widespread and more difficult to control depolarization evoked by distant electrodes. Local cathodal polarization was found to replicate all effects of cathodal tDCS hitherto demonstrated in the rat, including long-lasting facilitation of trans-synaptically evoked descending volleys and trisynaptically evoked EMG responses in neck muscles. It also replicated all effects of anodal tDCS in the cat. In both species, it increased the excitability of preterminal axonal branches of interpositorubral neurons up to 1 h post-tDCS. Local anodal polarization evoked opposite effects. We thus show that presynaptic actions of polarizing direct current may contribute to both immediate and prolonged effects of tDCS. © 2014 The Physiological Society.

Introduction: One of the factors which increase the rehabilitation efficacy and accelerate the convalescence and return to society of the patients after myocardial infarction may be the self-care attitude. Therefore it seems justifiable to seek such factors which will affect the self-care level. Self-estimation belongs to the most important determinants of coping efficacy and undertaking health behaviours. Considering that health behaviours may be treated as a behavioural manifestation of the self-care attitude, it is probable that the correlation between the self-image and self-care attitude appears to be strong. Aim: The aim of the research was determination of the strength of the correlation between the level of self-image and self-care attitude as well as the care types in patients after myocardial infarction. Methods: The study involved 127 persons who had myocardial infarction for the first time and did not undergo any other severe concomitant illnesses. The study covered 28 women and 99 men aged from 39 to 81, with the average age 57.74. The study consisted in completing the KTS questionnaire measuring the self-care level and OS questionnaire measuring the self-image level. The results were analysed statistically and discussed. Results: Analysis of the levels of self-care and self-image in patients after myocardial infarction showed a strong correlation between those variables at the 0.01 significance level. It is a linear correlation which means that the higher the self-image level, the higher the self-care level. This rule applies to each of the care dimensions, i.e. responsibility, involvement and future perspective as well as each of the types of self-care. Conclusions: The research indicated a strong correlation between the self-care level and types and the self-image level in those who underwent myocardial infarction. It appeared that the higher the self-image level after myocardial infarction, the higher the self-care level and the fuller the self-care. Therefore the self-acceptance level should be increased in the patient, because in the case of those who underwent myocardial infarction it is extremely important for development of the self-care attitude. A change in the self-image from negative into positive may be directly translated into an increase in the self-care level.

The aim of the study was to find factors which differentiate generally healthy elderly men who had fallen versus those whom had not fallen throughout the year prior to the study. The participants (66 generally healthy men aged over 70 years) were divided into two groups - those who had fallen (F) and those who had not fallen (NF) in the period of one year before the study. Their body mass index and fat mass were measured. On the basis of the value of maximum sways on a stable posturographic platform, the sway area was calculated. To study psychomotor fitness reaction time, an analysis was measured by the "Vienna System Test". Functional fitness was measured on the basis of selected tests from "The Senior Fitness Test". The complexity of the multiple mechanisms underlying postural control does not allow for clear indication of the risks of stability loss. The experimental group of men over 70 yrs who had fallen (F) was characterised by lower body strength (p<0.05) and endurance (p<0.05), compared to NF group. Exercise programs designed to prevent accidental falls should incorporate strength and aerobic exercises.


Introduction: Low level of participation in cardiac rehabilitation patients after myocardial infarction is one of the most important problems in cardiology. Participation in cardiac rehabilitation process depends on many diverse factors and one of the fundamental ones is self-care attitude. It is very important to find predictors which can effective influence this attitude. If we can understand some of the self-care attitude predictors, we might be better prepared to lead very effective and much faster rehabilitation. The presented studies relate to the above mentioned issues. Study aim: The studies were aimed at determination of the extent of correlation between selfcare attitude in patients after myocardial infarction and time of rehabilitation process, physical condition and time from myocardial infarction accident. Methods: The studies were performed on a group of 127 patients, 28 women and 99 men, after myocardial infarction, who were subjected to cardiac rehabilitation. The studies comprised filling out questionnaire that appraise self-care attitude and personal data. Results were then subjected to statistical analysis and discussion. Results: The study found that there is no correlation between self care attitude, time from myocardial infarction accident and physical condition of the patients after myocardial infarction. There is a correlation between mental and social self care and time of the rehabilitation process. Conclusion: Results suggest that time of the rehabilitation process after myocardial infarction can be an important factor influencing people's self care attitude, especially in mental and social area. Although there was no relation between self care attitude and time from myocardial infarction, the results show that there is a trend in this connection that might be important. Further research of this problem should be encouraged.

Introduction: The low level of participation in cardiac rehabilitation of patients after myocardial infarction is one of the most important problems in cardiology. Participation in the cardiac rehabilitation process depends on many diverse factors and one of the fundamental ones is a self-care attitude. It is very important to find predictors which can effectively influence this attitude. If we can understand some of the self-care attitude predictors, we might be better prepared to lead a more effective and much faster form of rehabilitation. The presented studies relate to the above mentioned issues. Material and methods: The studies were performed on a group of 127 patients, 28 women and 99 men, after myocardial infarction, who were subjected to cardiac rehabilitation. The studies comprised filling out a questionnaire that appraises self-care and personal data. Theresults were then subjected to statistical analysis and discussion. Results: The study found that there is no correlation between the self care, age and socioeconomic status of the patients after myocardial infarction. There is a correlation between educational level and self care (0.01) and mental self care and gender (0.05). There is no correlation between general self care and gender. Conclusion: It resulted from the studies that along with the level of education the level of self care increases. Results suggest that the education of the patients after myocardial infarction can be an important factor influencing people's self care. Results also indicate that women have a higher level of mental self care than men do. Although there was no relation between self care, age and socioeconomic status, the results show that there is a trend in this connection that might be important. Further research into this problem should be encouraged.

Introduction: This study compared the effectiveness of two different kind of massage: therapeutic and deep tissue on chronic low back pain. Methods: The research was made on 26 patient aged from 60 to 75 years who were seperated into 2 groups: I [n=13] and II [n=13]. Group I had therapeutic massage [TM] which uses effleurage, petrissage, tapping and friction. Group II had deep tissue massage [DTM] which uses oblique pressure, a combination of lengthening and cross-fiber strokes, anchor and stretch, freeing muscle from entrapment. TM and DTM lasted for 10 days, each 30 min and were made by qualify massage therapist. Both groups did not have other treatment. Outcome measures obtained at baseline and after treatment consisted of Modified Oswestry Low Back Pain Disability Index [ODI], Quebec Back Pain Disability Scale[QBPD] and Visual Analog Scale [VAS]. Results: There was not statistically significant differences between groups according to age and BMI. Statistically significant differences were noted after TM in every test [ODI p=0.010; QBPD p<0.001; VAS p<0.001] and after DTM in every test [ODI p<0.001; QBPD p<0.001; VAS p<0.001]. DTM was statistically significant better therapy than TM in ODI [p=0.038] and VAS [p=0.015]. Further research is needed to verify the results. © 2012 The authors and IOS Press. All rights reserved.

The aim of this paper is to present the morphological features of rowers. The objective is to establish the type of body build best suited to the present requirements of this sports discipline through the determination of the most important morphological features in rowing with regard to the type of racing boat. The subjects of this study included competitors who practise rowing and were members of the Junior National Team. The considered variables included a group of 32 anthropometric measurements of body composition determined using the BIA method among male and female athletes, while also including rowing boat categories. In order to determine the analysed structures of male and female rowers, an observation analysis was taken into consideration and performed by the k-means clustering method. In the group of male and female rowers using long paddles, higher mean values for the analysed features were observed, with the exception of fat-free mass, and water content in both genders, and trunk length and horizontal reach in women who achieved higher means in the short-paddle group. On the men's team, both groups differed significantly in body mass, longitudinal features, horizontal reach, hand width and body circumferences, while on the women's, they differed in body mass, width and length of the chest, body circumferences and fat content. The method of grouping used in this paper confirmed morphological differences in the competitors with regard to the type of racing boat.


INTRODUCTION: Volleyball is a source of direct injuries and chronic overloads of the joints, which indirectly results in traumas and permanent dysfunctions. This applies particularly to: knee joints, ankle joints, shoulder joints and small joints of the hand, as well as the joints of the lower spine regions. Each league team should employ a physiotherapist who would be responsible for the implementation of an injury prevention program as well as for choosing the right training loads. PURPOSE: The purpose of this study is to analyze the frequency and the type of knee joint injuries occurring in people practicing Volleyball at competitive level as well as to propose the usage of elements of modern physiotherapy in order to prevent these injuries. MATERIAL AND METHODS: The tests were performed over a group of 19 volleyball players from Poznan. In order to propose measures that would prevent injuries, the authors carried out a review of modern physiotherapy methods and suggested the implementation of certain therapeutic techniques for the region of the knee joint. RESULT ANALYSIS AND DISCUSSION: As much as 79% of the subjects reported having chronic pain and knee joint injuries in the past. All of them, due to their conditions, declared having used various forms of physiotherapy treatment. It seems that in a professional sports club not only the presence of a massage therapist but first of all a qualified physiotherapist is indispensable.
