Published: June 2013

IntroductionIn adult cancer patients, physical activity (PA) and fitness have been repeatedly shown to correlate with, and improve, many mental and physical measures including decreased cancer recurrence and mortality.Childhood cancer survivors are at an increased risk of many medical and psychosocial conditions in adulthood, including low bone density, obesity, diabetes, cardiovascular disease, secondary tumors, and low quality of life. PA may alleviate all of these simultaneously, yet very few studies had been conducted in this filed to-date, and results were generally disappointing.AimTo measure the effect of physical activity on aerobic fitness, body composition, bone density, mood and quality of life of young childhood cancer survivors.MethodsAfter screening 230 medical records of children from the follow-up clinic of the Hemato-Oncologic Department at the Edmond and Lily Safra Children's Hospital, 85 were deemed eligible by inclusion and exclusion criteria and invited to participate; 25 children agreed, and 23 entered the study. Ten were referred to an exercise group, which performed 2–3 exercise sessions per week for 6 months, and 13 maintained their usual lifestyle. At baseline and after 6 months, we measured aerobic fitness by cardio-pulmonary exercise testing; body composition and bone density by DEXA; and health-related quality of life and mood by validated questionnaires (PedsQL and CDI, respectively).ResultsTwenty-two children (96%) completed the study. At baseline, exercise and control groups differed only by a higher proportion of children with obesity in the exercise group, with marginal statistical significance (60% vs. 17%, p=0.07). All children had normal bone mineral density and quality of life measures.Aerobic fitness improved only in the exercise group, with marginal statistical significance (p=0.068). No between-group differences were found in changes of BMI, BMI z-scores, body fat percentage, bone density indices, mood or quality of life.After pooling both study groups together, significant correlations were found between the change in aerobic fitness and changes in lean body mass (r 2=0.806, p<0.001), femoral neck bone mineral density (r 2=0.604, p=0.022), bone mineral content (r 2=0.542, p=0.037), and social quality of life (r 2=0.572, p=0.016).ConclusionsExercise training improves aerobic fitness in childhood cancer survivors, yet the small sample size did not allow identification of additional expected benefits. Nevertheless, changes in fitness over 6 months were significantly correlated with measures of body composition, bone health and quality of life.Childhood cancer survivors should be continuously encouraged to exercise, in order to both improve their immediate well-being, and to decrease their risks for potential late effects of pediatric cancer.The study was funded by the Israel Cancer Association.

BackgroundFor football referees supervision of a match means significant mental burden. During the match they have to deal with many disputable moments. Their decisions can evoke negative emotions both in players and spectators. Referees often cannot cope with such a burden and leave the match depressed.1The main goal of this research was to reveal some of the factors which contribute to such situations.MethodsSubjective psychological experiences and mental states of 26 football referees were evaluated. These referees supervise football competitions in one of the 14 regions of the Czech Republic.For evaluating their subjective psychological experiences and states the standardised questionnaire SUPSO2was used. The questionnaire was filled in twice: before the match and immediately after the match. Temperament of referees was evaluated using standardised Belov's temperament test.3To determine and describe potential causes of changes in mental states of football referees caused by a completed match factor analysis was used.ResultsImportant factors which best reflect the dynamics of changes of subjective experiences and states of football referees were described. Most of the identified factors proved to be only consequences of the relationship among detected components of mental states assessed by the questionnaire SUPSO or were mainly related to the temperament of each referee. It was found, however, that one of these factors is strongly saturated by the referee's actual mental state before the match. This factor represents a significant agent altering referee's mental state during the given match.ConclusionsMental state of football referees just before a match determines partially the ability to manage psychological burden connected to the supervised match. Pre-match preparation should therefore focus more on a regulation of the referees' actual mental state (“pre-start mental state”). If the referees do not use regulation techniques leading to the elimination of negative mental states, it can result in stagnation or decline in their performance level.

Research background and hypothesisOverhead athletes are having higher risk to suffer from acute and chronic shoulder injuries.Research aimto evaluate shoulder complex functional characteristics of the overhead and non-overhead young athletes before and 2 years after the concomitant arthroscopic type II superior labrum anterior posterior (SLAP) and partial–thickness rotator cuff (PTRC) repair and to present specific rehabilitation guidelines needed for successful return to sports.MethodsThe sample of the research included 38 male athletes: overhead (n=19) and non-overhead (n=19) athletes. All participants underwent concomitant arthroscopic type II SLAP and PTRC repair and were available for review at a minimum of 2 year after surgery. Shoulder range of motion was measured with goniometer. Constant score was used for evaluation of the shoulder function's quality.ResultsFunction of the shoulder complex had higher increase in non-overhead group (p<0.05). Constant score 2 years after surgery hadn't returned to optimal level. Shoulder flexion and internal rotation ROM in both groups and external rotation ROM of non-overhead athletes were the same as before surgery.Discussion and conclusionFunctional characteristics of shoulder complex measured with Constant score of overhead and non-overhead athletes statistically significant increased 2 years after the arthroscopic surgery. Significant change of external rotation was established in overhead athletes: 2 years after surgery it was significantly smaller. Sports specific and diagnose-based rehabilitation is needed to decrease deficit in function of the shoulder complex after concomitant arthroscopic type II SLAP and PTRC repair.

BackgroundAn important number of sport modalities sustain its performance in the capacity to repeat efficiently a sport movement without fatigue. However, it is a fact that this mechanism will appear and affect the athletes' velocity magnitudes. The aim of this study was to compare the Peak Velocity (PV) in two protocols: Traditional Training (TT) vs. 20 s inter-repetition rest (IRR) with the Optimal Load (OL) for the maximal Power output (OL: 50.7±8.0% of 1-RM).MethodsFifteen male, physical education students, participated in this study (age: 23.1±1.6 years; height: 177.1±7.7 cm; mass: 76.2±9.2 kg; 1-RM: 93.8±14.3 kg; 1-RM/mass: 1.24±0.21). After the validation of the bench press 1-RM and determination of OL, all participants performed two sets of work: TT (1 set×continuous repetitions to failure) and IRR (1 set×15 repetitions with 20 s rest between repetitions).ResultsIn the TT, VP decreased significantly from the third repetition (3.7±1.2 repetition) with loses of 17.8% (p≤0.014; ES: -0.53; IC: 0.046–0.243) (1st repetition: 0.75±0.18 m•s-1; 3rd repetition: 0.62±0.14 m•s-1). In IRR, VP magnitudes did not decrease significantly along the 15 repetitions (1st repetition: 0.67±0.23 m•s-1; 15th repetition: 0.64±0.12 m•s-1). Also, among our sample participants, there were no correlations found between VP and strength levels. Conclusions: While in TT fatigue is manifested in significant velocity loses, in IRR the movement mechanical efficiency and the mechanical parameters remain stable along the fifteen assessed repetitions. Consequently, we can conclude that the addition of inter-repetition rests (20 s) allows the performance of a higher number of movements without significant alterations or presence of fatigue along the set.

It is since the mid 80's that exercise and various forms of physical activity have been receiving both gradual interest and growth in the modern world as accumulating data have been demonstrating their relation to the prevention of and rehabilitation from several health conditions. In addition, the concern of establishing health related quality of life in our inactive, disease threatened societies has received great dimensions. Accordingly, the need to disseminate information, increase participation and adherence while avoiding injury as much as possible has become imperative and accurately expressed in the words of R.E. Sallis who stated that we must begin to merge the fitness industry with the health care industry if we are going to improve world health.E.B.C. is a training system that emerged out of the aforementioned facts and aims at fighting inactivity, promoting safety during exercise and everyday living, relieving stress and pain and thus promoting health in a general, pleiotropic way. E.B.C. is a carefully selected, creative, multidimensional application of the various, known elements that should underpin every exercise/physical activity regimen but are usually not. According to E.B.C. acquiring partial and total body consciousness enhances performance, technique, adaptations, injury prevention, stress management and finally retainability. E.B.C. is designed to precede all various modes of traditional and contemporary exercise but also to safely induce activity after rehabilitation. Through elaborated guidance and instruction the joints of the body are mobilized, realized and manipulated with special attention to movement patterns that exhibit low levels of consciousness and/or adequate problems. Physical execution is always accompanied by information on body construction and function as well as injury prevention. Mental support, continuous assiduity and emotional well-being are also provided. The fields of sports'n'exercise medicine, physiotherapy and health'n'fitness are reflected in the system and are continually supporting, adjusting, progressing and updating it in order to increase its effectiveness upon public health.

BackgroundReturn-to-play (RTP) criteria after a sport injury represent a key point in order to decrease the risk of subsequent re-injury.ObjectiveTo analyze how clinicians decide, in their daily practice, when a hamstring injured professional soccer player is fully able to get back to competitive activities.MethodsThirty-seven doctors for French and Belgian professional soccer clubs filled in a questionnaire formulated with multiple choice questions.ResultsNearly 80% of the questioned doctors declared to use at least 7 criteria in order to assess player's ability to return to competitive soccer after a hamstring injury. The most important ones are: complete pain relief, normalized muscle strength assessment, subjective feeling reported by the player, normalized flexibility and achievement of a specific soccer test. For some of these criteria, most notably muscle strength assessment, there is a lack of consensus about the choice of assessment parameters and the limit value allowing doctors to authorize or forbid RTP. Our study also highlighted the interest for clinicians to consider the opinion of physical therapists and physical trainers.ConclusionAfter a hamstring injury, clinicians for professional soccer clubs assess player's ability to return to full sport according to a “criteria-approach” instead of a “timed-based” approach. However, even if the scientific evidence about this topic is not sufficient at the moment, the implementation, in daily practice, of scientifically demonstrated assessment parameters and limit values should help the RTP decision and decrease the risk of re-injury.

Authors: Nitzsche Nico , Reinhardt Fritjof 
Published: June 2013

BackgroundThe degenerative cerebral microangiopathy (CMA) is a disease penetrating brain arteries with the result of single or multiple acute small subcortical infarcts with or without associated leukoencephalopathy. The consequences are focal neurological deficits, gait and balance disorders, and vascular dementia (de Laat. 2010 & 2012). Previously, stimulus set showed in neurological degenerative diseases due to the high density stimulus positive effects on motor activity (del Pozo Cruzet al2012; Claerboutet al2012). The prevalence in people over 60 years is at 20–30%. The pilot study was to examine the goal of a multi-week vibration training on motor performance of patients.MethodsThirty-two patients (72.7±8.5 years, BMI 28.9±4.3 kg/m2) with mild to moderate CMA were studied before and after training on postural control (C1=Condition 1 & C2=Condition 2), isometric trunk strength, hand strength response and quality of life (SF 36). The measurements of postural control were in the upright position on an unstable platform and have a quiet place with disturbance (Haider Posturomed®). The oscillation travel (s) and oscillation velocity (v) (Noraxon® 6g) of the stood plate were observed. The strength of the hull (anterior/posterior) and the hand (Vernier®) were measured isometrically (Dr. Wolf® Back Check). The assessment of gait (30m) was performed using an inertial sensor (Lokometrix®). A thirty meters distance has been covered. Step frequency, stride length, walking speed and symmetry were measured. Training was performed 3 times weekly for 10 weeks on a vibration plate (Galileo®) with sinusoidal oscillations. Static and dynamic exercises were used while standing.ResultsThere were completed 23±3.2 training sessions (16.7±4 minutes. 20.5±4.6 Hz. A=4mm). Postural control (C1: sprä=0.66±0.9 m vs. spost=0.33±0.3 m; vprä=4.4±5.6 m/s vs. vpost=2.5±3.9 m/s. C2: speed: vprä=9.1±6.2 m/s; vpost=6.2±3.2 m/s; sprä: 1.0±0.8 m; spost 0.5±0.2 m) improved in both conditions significantly (p<0.01). There were significant increases in isometric trunk strength (ventral: 2.8±1.3 to 3.3±1.4 N/kg; dorsal: 3.4±1.8 to 3.9±2.1 N/kg; p<0.01) and improvements in five of eight items in quality of life (physical function, role function of physical body, general health, social functioning, emotional role; p<0.01). Changes in gait and hand strength were not available (p>0.05).DiscussionInitial findings by vibration training on motor performance could be gained. Several weeks of vibration training could become a key therapeutic approach for Training CMA present affecting the motor skills disorders positively. Postural control and quality of life appear as signficantly improved values. Often these are important requirements for activation of bodys. The next step should be followed by a randomized trial.

BackgroundNeuromuscular training protocols that plyometrics, dynamic balance exercises, agility training, etc, can significantly improve biomechanics and neuromuscular performance and reduce anterior cruciate ligament (ACL) injury risk in athletes.1 2ObjectiveThe purpose of this study was to investigate the effect of 6weeks TDS Jump training on muscle reaction time after surgical reconstruction of the ACL.MethodsSeven patients men 12 to 36 months following reconstructive ACL operation continuously participated TDS Jump training at seven sets of five times (7 sets×5 times=35 jumps), 3 days/week, for 6 weeks. Premotor reaction time (PRT) of vastus medialis (VM), vastus lateralis (VL), hamstring medialis (HM), and hamstring lateralis (HL) were recorded by electromyography through the examination sudden knee eversion stress. Two physical therapists evaluated each subject's performance ability using a talent diagnose system (TDS Jump).ResultsPRT of all tested muscles were significantly decreased after both three and six weeks of TDS Jump training than at before training (p<.05). Grounding time (TDS Jump) of operated legs was significantly decreased after both three and six weeks of TDS Jump training than at before training (p<.05).ConclusionsThese results demonstrated in the present that TDS Jump training could improve PRT and grounding time in operated legs. Therefore, suggested that TDS Jump training applying in not only an assessment of the neuromuscular function after reconstructive ACL operation but also training and rehabilitation.
CORRECT NUTRITION AND SUPPLEMENTS HAS SIGNIFICANT EFFECTS ON ANAEROBIC POWER AND CAPACITY OF LOWER AND UPPER LIMBS OF ELITE WRESTLERS
Authors: Abbasalipour Masoud 
Published: June 2013

AimThe aim of study was to investigate the influence of correct nutrition, creatine and glutamine supplements on anaerobic power, capacity of upper and lower limbs of the elite wrestlers of Mazandaran province, Iran.Materials and methodsThe samples for this study consisted of 18–27 years old elite wrestlers. The voluntaries were divided into creatine, glutamine, supplement, correct nutrition and control groups. After a usual warm-up exercise for 15 minutes, the participants exercised with a hand and bicycle ergometer with the maximum energy till the point of complete exhaustion and afterwards physical performance tests were carried out. Paired t test was used for measurement of anaerobic power.ResultsAs have shown the results the effect of correct nutrition, supplements (creatine and glutamine) on anaerobic power and capacity of lower and upper limbs of elite wrestlers of Mazandaran province, there was practically no need to use a glutamine as a separate supplement cause of its lower efficiency. As about creatine supplement have to say that surely it have a positive effect on the anaerobic power and capacity of upper and lower limbs.ConclusionThe effect of correct nutrition, supplements (creatine and glutamine) on anaerobic power and capacity of lower and upper limbs of elite wrestlers of Mazandaran province, there is practically no need to use a glutamine as a separate supplement cause of its lower efficiency. As about creatine supplement have to say that surely it have a positive effect on the anaerobic power and capacity of upper and lower limbs, but despite the known fact that diet cannot provide the necessary creatine quantity we prove by our study that depend on type of diet and ingredients quantity and quality it is possible to reach the same results as if we use the supplements itself.

Published: June 2013

ObjectivesTo compare eccentric exercises as proposed by Alfredson with eccentric and static exercises as proposed by Stanish in the management of Achilles tendinopathy.MethodsPatients with midportion Achilles tendinopathy for at least 3 months were included in this trial. They were sequentially allocated to receive either Alfredson's exercise programme or Stanish's exercise programme. Outcome measures were pain and function using the VISA-A score. Patients were evaluated at baseline, at the end of treatment (week 12), and six months (week 36) after the end of treatment.Results41 patients met the inclusion criteria. At the end of treatment, there was a rise in VISA-A score in both groups compared with baseline (p<0.05, paired t-test). There were significant differences in the VISA-A score between the groups at the end of treatment and at the 6-month follow up; Alfredson exercise programme group produced the largest effect (p<0.0005, independent t-test).ConclusionAn exercise programme based on Alfredson protocol was superior to Stanish model to reduce pain and improve function in patients with Achilles tendinopathy at the end of the treatment and at the follow-up. Further research is needed to confirm our results.

Abstract
Growing evidence supports a role for the unfolded protein response (UPR) in carcinogenesis; however, the precise molecular mechanisms underlying this phenomenon remain elusive. Herein, we identified the circadian clock PER1 mRNA as a novel substrate of the endoribonuclease activity of the UPR sensor IRE1α. Analysis of the mechanism shows that IRE1α endoribonuclease activity decreased PER1 mRNA in tumor cells without affecting PER1 gene transcription. Inhibition of IRE1α signaling using either siRNA-mediated silencing or a dominant-negative strategy prevented PER1 mRNA decay, reduced tumorigenesis, and increased survival, features that were reversed upon PER1 silencing. Clinically, patients showing reduced survival have lower levels of PER1 mRNA expression and increased splicing of XBP1, a known IRE-α substrate, thereby pointing toward an increased IRE1α activity in these patients. Hence, we describe a novel mechanism connecting the UPR and circadian clock components in tumor cells, thereby highlighting the importance of this interplay in tumor development.
