Injuries to the hamstring muscles are common in athletes. Track and field, Australian football, American football and soccer are examples of sports where hamstring injuries are the most common. The purpose of this study was to investigate whether there is a correlation between a hamstring injury prognosis and its characteristics of imaging parame-ters. The literature search was performed in the databases PubMed and CINAHL, and eleven articles were included. Seven out of the 11 ar-ticles showed a correlation between the size of the hamstring injury and length of time required before returning to sports. Different authors have reported contrasting results about length of time required before returning to sports due to location of injury within specific muscle. Ma-jority of the articles found hamstring strain correlated to an extended amount of time required before returning to sports.

As the radical prostatectomy (RP) for the patient diagnosed as localized prostate cancer has been increasing, erectile dysfunction (ED) associat-ed with RP is increased and ED after RP is a significant risk factor to re-duce the quality of life for the patient after RP. Therefore, the treatment concept called penile rehabilitation was introduced and phosphodies-terase type 5 inhibitor (PDE5I) is used widely for the prostate cancer pa-tient after RP. Generally PDE5I is considered as safe and effective drug for the prostate cancer patient after RP. Recently, a report against the general opinion that PDE5I use is safe in the patient with prostate cancer was reported and the analysis of 5-yr biochemical recurrence-free sur-vival after RP between the PDE5I users and non-PDE5I users after bilat-eral nerve sparing RP showed decreased 5-yr biochemical recur-rence-free survival in the PDE5I users. In addition, a longitudinal cohort study reported that sildenafil, a kind of PDE5I, use might be associated with the development of melanoma and this result suggested the possi-bility of adverse effect of PDE5I on some kinds of cancers as well as prostate cancer. Moreover, the studies to evaluate the influence of nitric oxide (NO) and guanosine monophosphate (cGMP) signaling pathway associated with PDE5 showed both cancer reduction and cancer devel-opment. Therefore, the role of NO and cGMP signaling pathway in can-cer was reviewed based on the previous studies and suggested the ne-cessity of further clinical studies concerning about the safety of PDE5I in prostate cancer.

Autism is a neurodevelopmental disorder and this disorder shows im-pairment in reciprocal social interactions, deficits in communication, and restrictive and repetitive patterns of behaviors and interests. The effect of music on short-term memory in the view of cell proliferation in the hippocampus was evaluated using valproic acid-induced autistic rat pups. Animal model of autism was made by subcutaneous injection of 400-mg/kg valproic acid into the rat pups on the postnatal day 14. The rat pups in the music-applied groups were exposed to the 65-dB com-fortable classic music for 1 hr once a day, starting postnatal day 15 and continued until postnatal day 28. In the present results, short-term memory was deteriorated by autism induction. The numbers of 5-bro-mo-2ʹ-deoxyridine (BrdU)-positive, Ki-67-positive, and doublecortin (DCX)-positive cells in the hippocampal dentate gyrus were decreased by autism induction. Brain-derived neurotrophic factor (BDNF) and ty-rosine kinase B (TrkB) expressions in the hippocampus were also sup-pressed in the autistic rat pups. Music application alleviated short-term memory deficits with enhancing the numbers of BrdU-positive, Ki-67-positive, and DCX-positive cells in the autistic rat pups. Music ap-plication also enhanced BDNF and TrkB expressions in the autistic rat pups. The present study show that application of music enhanced hip-pocampal cell proliferation and alleviated short-term memory impair-ment through stimulating BDNF-TrkB signaling in the autistic rat pups. Music can be suggested as the therapeutic strategy to overcome the autism-induced memory deficits.

Physical exercise is one of the most effective methods for managing obesity, and exercise exerts positive effects on various brain functions. Excessive weight gain is known to be related to the impairment of cog-nitive function. High-fat diet-induced obesity impairs hippocampal neu-roplasticity, which impedes cognitive function, such as learning ability and memory function. In this study, we investigated the effect of tread-mill exercise on impairment of cognitive function in relation with hippo-campal neuroplasticity using high-fat diet-induced obese mice. After obesity was induced by a 20-week high-fat (60%) diet, treadmill exer-cise was performed for 12 weeks. In the present results, cognitive func-tion was impaired in the high-fat diet-induced obese mice. Brain-de-rived neurotrophic factor (BDNF) and tyrosin kinase B (TrkB) expression and cell proliferation were decreased in the high-fat diet-induced obese mice. Treadmill exercise improved cognitive function through enhanc-ing neuroplasticity, including increased expression of BDNF and TrkB and enhanced cell proliferation. The present results suggest that tread-mill exercise enhances hippocampal neuroplasticity, and then potential-ly plays a protective role against obesity-induced cognitive impairment.

The purpose of this study was to investigate the expression of lipogene-sis- and lipolysis-related genes and proteins in skeletal muscles after 12 weeks of resistance training. Sprague-Dawley rats (n=12) were ran-domly divided into control (resting) and resistance training groups. A tower-climbing exercise, in which rats climbed to the top of their cage with a weight applied to their tails, used for resistance training. After 12 weeks, rats from the resistance training group had lower body weights (411.66±14.71 g vs. 478.33±24.63 g in the control), there was no signifi-cant difference between the two groups in the concentrations of total cholesterol, and high or low density lipoprotein cholesterol. However, the concentration of triglyceride was lower in resistance-trained rats (59.83±14.05 μg/mL vs 93.33±33.89 μg/mL in the control). The mRNA ex-pression levels of the lipogenesis-related genes sterol regulatory ele-ment binding protein-1c, acetyl-CoA carboxylase, and fatty acid syn-thase were not significantly different between the resistance-trained and control rats; however, mRNA expression of the lipolysis-related carnitine palmitoyl transferase 1 and malonyl-CoA decar-boxylase in-creased significantly with resistance training. AMP-activated protein kinase protein levels also significantly increased in resistance training group compared with in the control group. These results suggested that resistance exercise training contributing to reduced weight gain may be in part be due to increase the lipolysis metabolism and energy ex-penditure in response to resistance training.

In this study we investigated the effect of a dual task (DT) comprised of a nonfatiguing leg and foot extension coupled with a calculation task on postexercise facilitation (PEF) of motor evoked potentials (MEPs) tested by using transcranial magnetic stimulation (TMS). Twelve right-handed healthy subjects participated in the study. They were required to per-form a motor task, a cognitive task and a DT. The motor task consisted of extending the right leg and foot for 30 sec at 20% of the maximal vol-untary contraction. The cognitive task consisted of a 30-sec backward calculation. In the DT condition, motor and cognitive tasks were per-formed concurrently. Resting motor threshold and 10 MEPs were col-lected before and immediately after each task. TMS was delivered to the motor hot spot of the right vastus lateralis and tibialis anterior (TA) muscles. Results showed that exercise induced a significant PEF in both VL and TA muscles while calculation was not associated with sig-nificant PEF. Furthermore, DT was associated with lack of significant PEF in both muscles (VL, 116.1%±9.6%; TA, 115.7%±9%). Our data indi-cates DT interference on corticospinal excitability after a nonfatiguing exercise. Our experimental paradigm may be used to address postexer-cise motor cortex plastic adaptations induced by motor and cognitive tasks of different complexity in sport, aging and neuropsychiatric dis-eases.

This study aims to verify the effectiveness of sleep education by identi-fying the differences of adaption to school and self-resilience of the high school students before and after sleep education for a certain pe-riod of time. The conclusion of this study is presented below: First, there were differences in adaptation to school and self-resilience of the high school students before and after sleep education for the high school students. After sleep education, adaptation to school environment and school friends became higher, and also the emotion control, personal relations and optimism, which are the subvariables of self-resilience, became higher. Second, there were differences in adaptation to school and self-resilience before and after sleep education by grade of the high school students. The freshmen’s adaptation to school friends and adaptation to school life, which are the subvariables of adaptation to school, increased after sleep education. The sophomores’ adaptation to school environment, which is the subvariable of adaptation to school, went up higher after sleep education. The freshmen’s emotion control, vitality and personal relations, which are the subvariables of self-resil-ience, were higher after sleep education. The sophomores’ personal relations, which are a subvariable of self-resilience, went up higher.

Foot biomechanics and core stability (CS) play significant roles in the quality of standing and walking. Minor alterations in body composition may influence base support or CS strategies. The aim of this study was to investigate the effect of the body mass index (BMI) on the foot pos-ture index (FPI) and CS in a healthy adult population. A total of 39 healthy adult subjects with a mean age of 24.3±6.4 yr and overweight BMI values between 25 and 29.9 kg/m2 (27.43±6.1 kg/m2) participated in this study. Foot biomechanics were analyzed using the FPI. CS was as-sessed using a plank test with a time-to-failure trial. The Spearman cor-relation coefficient indicated a significant correlation between BMI and both the FPI (r=0.504, P=0.001) and CS (r=-0.34, P=0.036). Present study concluded that an overweight BMI influences foot posture align-ment and body stability. Consequently, BMI should be considered during rehabilitation management for lower extremity injuries and body balance.

This study measured surface electromyography of the biceps brachii and triceps brachii during repeated drum playing with and without a drumstick to better understand activation of the upper arm muscles and inform the use of instrument playing for motor rehabilitation. A total of 40 healthy college students participated in this study. All participants were asked to strike a drum with their hand and with a drumstick at three different levels of stroke: soft, medium, and strong. The stroke or-der was randomly assigned to participants. A sound level meter was used to record the intensity of the drum playing. Surface electromyog-raphy signals were recorded at every hit during drum playing both with and without the drumstick in each of the three stroke conditions. The results demonstrated that the highest muscle activation was observed in both biceps brachii and triceps brachii with strong drum playing with and without the drumstick. A two-way repeated measures analysis of variance showed that there was a significant main effect for stroke in-tensity in muscle activation and produced sound level. While higher ac-tivation of the triceps brachii was observed for drum playing without a drumstick, no significant differences were found between the biceps brachii and sound level. This study demonstrated via surface electro-myography data that greater muscle activation of the biceps brachii and triceps brachii does not occur with the use of drumsticks in drum playing. With the drum sound controlled, drum playing by hand can be an effective therapeutic intervention for the upper arm muscles.

Health care in the ageing population is becoming a crucial issue, due to the quality of life. Physical activity, is of primary importance for older adults. This report compared the physical activity in two active older adults population with functionality, quality of life, and depression symp-toms. A cross-sectional study was developed with 64 older adults. Physical activity was assessed through the Yale Physical Activity Sur-vey for classification into a less activity (LA) group and a more activity (MA) group. Afterwards, the other health variables were measured through specific questionnaires: the quality of life with the EuroQol (Eu-roQol five dimensions questionnaire, EQ-5D), functionality with the Berg balance scale (BBS) and depression symptoms with the geriatric de-pression scale (GDS). There is a statistical significant difference be-tween groups for the BBS (t=2.21; P=0.03, d=0.27). The Pearson cor-relation analysis shows in LA group a moderate correlation between the BBS and age (r=-0.539; P<0.01) and EQ-5D (r=0.480; P<0.01). Moreover, both groups had a moderate negative correlation between GDS and the the EQ-5D time trade-off (r=-0.543; P=0.02). Active older adults with different amounts of physical activity differ in the BBS. This functional score was higher in the MA group. When observing to quali-ty of life, only the LA group was negatively associated with age while in both groups were associated with depression index.

This study investigated the prevalence, magnitude, and methods of rap-id weight loss among male and female Taekwondo athletes from all competitive levels. A questionnaire was administered to 72 men (re-gional/state level, n=31; national/international level, n=41) and 44 women (regional/state level, n=9; national/international, n=35). Among the male athletes, 77.4% of the regional/state level and 75.6% of the na-tional/international athletes declared to have reduced weight to com-pete in lighter weight categories. Among women, 88.9% of regional/state level and 88.6% of national/international level reported the use of rapid weight loss strategies. Athletes reported to usually lose ~3% of their body weight, with some athletes reaching ~7% of their body weight. The methods used to achieve weight loss are potentially dan-gerous to health and no difference between sexes was found. Four methods were more frequently used by men athletes in higher competi-tive levels as compared to lower levels, as follows: skipping meals (Z=2.28, P=0.023, η2=0.21), fasting (Z=2.337, P=0.019, η2=0.22), re-stricting fluids (Z=2.633, P=0.009, η2=0.24) and spitting (Z=2.363, P=0.018, η2=0.22). Taekwondo athletes lost ~3% of their body mass, us-ing methods potentially dangerous for their health. Although no differ-ence was found between sexes, lower level athletes more frequently used methods such as skipping meals, fasting, restricting fluids and spitting. Considering that these health-threating methods are more commonly used by lower level athletes, specific education programs should be directed to them.

The purpose of this study was to compare of tests for measuring maxi-mal exercise ability in elite swimmers. The high-school male elite swim-mers (n=17) were performed maximal exercise ability tests. The exper-imental method consisted of a crossover design at 1-week intervals with the swimming tests (field test, water VAMEVAL test, 200-m test, and 400-m test) in random order. It measured the heart rate, ratings of perceived exertion (RPE), and lactate level by physiological factors, and swimming velocity (SV), stroke rate (SR), and stroke length (SL) by me-chanical factors. The change of SV, SR, and SL in swimming tests was no significantly different. To compare tests, however, the lactate level and RPE in 200-m test was higher than water VAMEVAL test. The RPE of the 200-m and 400-m tests were higher than the field test and the wa-ter VAMEVAL test. Correlations showed between the field test and the 400-m test in heart rate and RPE. Moreover, a correlation observed be-tween the field test and 200-m test in heart rate. In this study, 200-m and 400-m tests were suit to apply the test methods for establishing the ex-ercise intensity appropriate for the underwater training of swimmers.

The purpose of this study was to evaluate the effectiveness of a treat-ment for patients with cervicogenic dizziness that consisted of thera-peutic education and exercises. The Dizziness Handicap Inventory and Neck Disability Index were used. Secondary outcomes included range of motion, postural control, and psychological variables. Seven patients (two males and five females) aged 38.43±14.10 with cervicogenic dizzi-ness were included. All the participants received eight treatment ses-sions. The treatment was performed twice a week during a four weeks period. Outcome measures included a questionnaire (demographic data, body chart, and questions about pain) and self-reported disability, pain, and psychological variables. Subjects were examined for cervical range of motion and postural control. All of these variables were as-sessed pre- and postintervention. Participants received eight sessions of therapeutic education patient and therapeutic exercise. The majority of participants showed an improvement in catastrophism (mean change, 11.57±7.13; 95% confidence interval [CI], 4.96–18.17; d=1.60), neck disability (mean change, 5.14±2.27.28; 95% CI, 3.04–7.24; d=1.32), and dizziness disability (mean change, 9.71±6.96; 95% CI, 3.26–16.15; d=1.01). Patients also showed improved range of motion in the right and left side. Therapeutic patient education in combination with thera-peutic exercise was an effective treatment. Future research should in-vestigate the efficacy of therapeutic patient education and exercise with larger sample sizes of patients with cervicogenic dizziness.

Although there is a limited amount of data regarding injuries incurred from yachting, identifying important trends can assist clinicians and yachters in the successful evaluation, treatment, and rehabilitation of injuries. Similar to other research studies related to sailing, the majority of injuries consist of orthopedic problems, with the highest rate of injury occurring in the lower legs and trunk. The most prevalent causes of in-jury were due to ‘over-action,’ followed by ‘insufficient practice,’ and lastly, ‘insufficient skill’ according to the responses among yachters. Gaining a better understanding of the causes of injury and the affected sites of injury will assist in developing a fitness training program for in-jury prevention and creating a rehabilitation program to ensure optimal conditions and safety for yachters.

To compare the two different anterior cruciate ligament surgery tech-niques’ effect in rehabilitation and activity performance. Fifty-five pa-tients were evaluated. Twenty-seven patients with transtibial technique (TT), 28 with anatomic single-bundle technique (AT) included. Tegner Activity Scale (TAS) was performed at preoperation and follow-up. The returning time of the sport and work was evaluated at follow-up. Sin-gle-leg hop test was performed at follow-up. Outcomes were compared between the two groups. The determined length difference between the operated knee and the intact knee was compared between the two groups. Average age of TT and AT was 27.9±6.4 yr, 28.3±6 yr, respec-tively. There was a significant difference between the two groups in du-ration of returning to sport. TT group had higher duration to return to sport (P<0.01). No difference between the two groups in duration of re-turning to work (P>0.05). There was a significant difference between the two groups. TT group had significantly higher values than AT group (P<0.01). No difference in TAS between the two techniques at preoper-ation and at last follow-up (P>0.05). The increase of TAS in patients who had AT was higher than the patients who had TT (P>0.05). No dif-ference in single-leg hop test at 55%–65%, 65%–75%, and 85%–95% level (P>0.05). In this test at 75%–85% TT group had higher values than AT group (P<0.05), AT group had higher values at 95%–105% level (P<0.05). Good short and long-term knee outcome scores depend on rehabilitation protocol after surgery. Surgery technique should provide the adequate stability in rehabilitation period. AT obtains better out-comes in rehabilitation.

The aim of this study was to determine whether there is an association between leukocyte telomere length (LTL), and estrogen level, oxidative stress, cardiovascular disease (CVD) risk factors, and cardiorespiratory fitness (CRF) in pre- and postmenopausal obese women. Fifty-four obese women (premenopausal, n=25; postmenopausal, n=29) were selected to participate in this study. The outcome measurements in the pre- and postmenopausal groups were compared using independent t-tests and Pearson correlation analysis. The estrogen level (P<0.001), LTL (P<0.05), high-density lipoprotein level (P<0.05), and CRF (P<0.001) were higher in premenopausal women than in postmenopausal wom-en. The body fat percentage (P<0.05) and triglyceride concentration (P<0.05) were lower in premenopausal women than in postmenopaus-al women. There were no significant associations between LTL, CVD risk, CRF, and oxidative stress and antioxidant enzyme activity in pre-menopausal women. The body mass index (BMI) and body fat percent-age in postmenopausal women were negatively associated with LTL (P<0.05). When all women were considered (i.e., both pre- and post-menopause), the BMI, percentage of fat, and waist circumference had a negative association with LTL (P<0.05), and estrogen levels were positively associated with LTL (P<0.05). Decreased estrogen levels af-ter menopause, a pivotal factor in the biology of aging, and obesity were more associated with shorter telomere lengths in pre- and postmeno-pausal women than aerobic capacity and other CVD risk factors.

The aim of this study was to investigate the effects of an 8-week Pilates exercise program on menopausal symptoms and lumbar strength and flexibility in postmenopausal women. In total, 74 postmenopausal wom-en were recruited and randomly allocated to a Pilates exercise group (n=45) and a control group (n=29). Menopausal symptoms were mea-sured through a questionnaire, while lumbar strength was measured through a lumbar extension machine, and lumbar flexibility was mea-sured through sit-and-reach and trunk lift tests performed before and after the Pilates exercise program, respectively. The Pilates exercises consisted of 7–10 min for warm-up, 35–40 min for the main program modified from Pilates Academy International, and 5–7 min for the cool-down, and were performed 3 times a week for 8 weeks. The results showed a significant decrease in menopausal symptoms except uro-genital symptoms. Also, the results presented a significant increase in lumbar strength and flexibility after 8 weeks of the Pilates exercise pro-gram. We concluded that an 8-week Pilates exercise program is effec-tive in decreasing menopausal symptoms and increasing lumbar strength and flexibility.
