Methamphetamine (METH) is a drug of abuse and neurotoxin that induces Parkinson's-like pathology after chronic usage by targeting dopaminergic neurons. Elucidation of the intracellular mechanisms that underlie METH-induced dopaminergic neuron toxicity may help in understanding the mechanism by which neurons die in Parkinson's disease. In the present study, we examined the role of reactive oxygen species (ROS) in the METH-induced death of human dopaminergic SK-N-SH cells and further assessed the neuroprotective effects of zinc and metallothionein (MT) against METH-induced toxicity in culture. METH significantly increased the production of reactive oxygen species, decreased intracellular ATP levels and reduced the cell viability. Pre-treatment with zinc markedly prevented the loss of cell viability caused by METH treatment. Zinc pre-treatment mainly increased the expression of metallothionein and prevented the generation of reactive oxygen species and ATP depletion caused by METH. Chelation of zinc by CaEDTA caused a significant decrease in MT expression and loss of protective effects of MT against METH toxicity. These results suggest that zinc-induced MT expression protects dopaminergic neurons via preventing the accumulation of toxic reactive oxygen species and halting the decrease in ATP levels. Furthermore, MT may prevent the loss of mitochondrial functions caused by neurotoxins. In conclusion, our study suggests that MT, a potent scavenger of free radicals is neuroprotective against dopaminergic toxicity in conditions such as drug of abuse and in Parkinson's disease.

The purpose of this study was to investigate the effects of exergame (Nintendo ® WiiFi™) on haemodynamics responses. Twenty participants with age 18-25 years old were participated in this study and were divided into two groups; active group (AG; n=10) and sedentary group (SG; n=10). On the experimental day, after resting for 10 min., participants performed exercise by using seven games of Nintendo Wii for 20 min. and recovery for 5 min. The haemodynamic variables including heart rate (HR), stroke volume (SV), cardiac output (CO), cardiac index (CI), ejection fraction (EF), and systemetic vascular resistance (SVR) were recorded in a real time on neck, sternum, rib closet to V6, and back by non-invasive technique (Physioflow ® ) throughout the experiment. The results showed that at rest, during exercise, and recovery period, the participants in AG had better blood circulation than those in SG, but no significant difference between groups. However, the value of EF in AG at recovery period was higher than that in SG and showed significant difference ( p <0.05) between groups. Therefore, exercise by exergame can improve the cardiac function in young adults. The AG had more responses to exergames than SG in some haemodynamics parameters.

The aim of this study was to measure heart rate (HR) and metabolic equivalent (MET) during exercise in supine (Sup), side-lying (Side-lying), sitting (Sit), standing (St) and walking position at the 1st (G1), the 2nd (G2), and the 3rd (G3) trimester in pregnant Thai women. Forty- two healthy active non-smoking pregnant women participated in this study and divided into G1, G2 and G3 groups depending on mean gestational ages at the time of testing. The values for HR and MET were measured using indirect calorimetry (IC, gas analyser) at rest and during exercise. Baseline assessments were made in the sitting recumbent position after a 30-minute stabilization period. Sequential measurements were then obtained in the following exercise positions; Sup, Side-lying, Sit, St and walking position, respectively. At rest compared with exercising in Sup position, the subject had tendency to decrease in HR, but statistically significant difference was found only in G3 group (P<0.05). St and Walking accelerated and increased HR more than the other three positions with the same of patterns in all gestation groups. The percentage of change in MET relative to resting position was significantly higher in walking than the other positions in all gestation groups (P<0.05). Our data strongly correlates with the American College of Obstetricians and Gynecologists guideline that recommends avoiding the Sup position post G1. We found walking to be the most spending cost of energy with respect to maternal MET output. Thus, we highly recommend pregnant women walk on a regular basis throughout pregnancy as this will also help maintain their aerobic fitness during pregnancy.

BACKGROUND AND PURPOSE Although Thai Yoga (TY) is reported to improve health-related fitness for the elderly, no study has yet carried out the effect of TY Program on physical mobility and lower-limb muscle strength in overweight/obese older women. MATERIALS AND METHODS In a randomized controlled pilot design, twenty-two sedentary women with a BMI ≥ 23 kg/m2, aged 62 ± 1 years were randomly assigned to either a TY group for 60 min, 3 times a week or to a "no exercise" control (CON) group. Sit and reach (SRT), functional reach (FRT) and 30-s chair stand (CST-30), 8-foot up and go (8UGT), 6-min walk (6MWT)) and lower-limb muscle strength were measured at the beginning, 4, and 8 weeks. RESULTS At week 4, a significant between groups was obtained in CST-30, 8UGT, and 6MWT. At week 8, FRT, 8UGT, 6MWT and knee flexor and extensor muscle strength were improved in the TY over the CON. Significant improvement was found in all variables within the TY, but no change was observed in the CON. CONCLUSION An 8-week TY program appears to provide beneficial improvements in physical mobility in overweight/obese older women.

The purposes of this study were 1) to evaluate the effects of modified hatha yoga on the injured workers after training for 8 weeks, and 2) to measure heart rate variability (HRV), stress responses, and physical fitness changes in the industrial injured workers. Twenty-six subjects (13 injured workers (IW) and 13 control normal workers (CN), aged between 18 to 60 years, volunteered to participate in this study. All participants were measured HRV, stress responses parameters including electromyography (EMG), respiratory rate, skin temperature and skin conductance. IW group were further divided into two groups; hatha yoga injured workers (YIW) (n=7) and control injured workers (CIW) (n=6). YIW group performed 60- minute/day, 3 days/week for 8 weeks of modified hatha yoga and then all parameters were measured again. Results showed that IW group had a significant increase in LF/HF ratio of HRV (2.41) and skin conductance (2.18 μS) compared to the CN group (HRV= 1.61, skin conductance = 1.24 μS) (p < 0.05). Conclusion: The injury from industrial work disturb balance of PNS and SNS activity. And the 8 week modified hatha yoga could not improve HRV and stress response in YIW group.

The aim of this study was to investigate physical fitness of children after participating a sports summer day camp 2558 at college of sports science, Mahidol Univesity for 3 weeks. A total of 146 boys (n=81) and girls (n=65), aged 6 to 12, were participated in this study. The physical fitness parameters in this study composed of 1) the body compositions, including the body weight (in kilogram; kg), body mass index (BMI, in kg/m 2 ), and waist circumference (in centimeter; cm), 2) upper and lower muscle strength, including bicep curls in 30 second test (times), standing board jump (in cm), and grip strength (in kg), 3) flexibility (in cm), using sit and reach test, and 4) cardiorespiratoty function (ml/kg/min) using an endurance shuttle run test. Results showed that the significant changes in physical fitness parameters after 3 weeks of summer camping ( p <0.001) were found in waist circumference (decresed from 63.05 + 9.59 cm to 56.38 + 9.51 cm in the boys and from 62.89 + 10.34 cm to 56.69 + 8.80 cm in the girls), the trunk flexibility (decresed from 2.45 + 4.57 cm to -0.29 + 6.19 cm in the boys), the bicep curls of elbow flexion (incresed from 27 + 11 times to 32 + 12 times in the boys), grip strength ( increased from 12.29+4.42 kg to 13.78+4.37 kg in the girls) and the standing board jump ( increased from 110.13 + 20.21 cm to 118.27 + 16.27 cm in the girls). From the results can be concluded that children who participating a sports summer day camp for 3 weeks had improved their physical fitness by reducing waist circumference as well as increasing upper and lower muscle strength and power. However, there were no changes in body weight and BMI in both boys and girls indicated healthy recipes for snacks and lunch meal should be concerned for the next year’s camping program. Moreover, adding the physical activity program to increase trunk flexibility and endurance are also recommenced. (Journal of Sports Science and Technology 2015;15(1): 213-222 )

BACKGROUND Children with chronic ankle instability (CAI) frequently experience ankle unsteadiness, causing trips, falls, and ankle sprain injuries resulting in poor quality of life. A specific exercise program focused on physical and psychological purposes in children with CAI is needed. OBJECTIVE The purpose of this study was to investigate the feasibility of a 4-week home-based exercise training using active video games (AVGs) on balance, motor proficiency, foot and ankle ability, and intrinsic motivation in children with CAI. METHODS Sixty children with CAI (10 ± 2 years) were randomly assigned to an experimental group (AVGs; n = 30) or a control group (CG; n = 30). The AVGs group played 2-selected video games, i.e., catching fish and Russian Block, while the CG group received the exercise program for CAI. Both programs were scheduled for 30 minutes per day, 3 times per week for four weeks at home. The single-leg stance test was used to assess static balance. The walking forward ...

Between 1999 and 2007, the Ministry of Health and Population in Egypt scaled up the Integrated Management of Childhood Illness (IMCI) strategy in 84% of public health facilities. This retrospective analysis, using routinely available data from vital registration, aimed to assess the impact of IMCI implementation between 2000 and 2006 on child mortality. It also presents a systematic and comprehensive approach to scaling-up IMCI interventions and information on quality of child health services, using programme data from supervision and surveys. We compared annual levels of under-five mortality in districts before and after they had started implementing IMCI. Mortality data were obtained from the National Bureau for Statistics for 254 districts for the years 2000-2006, 41 districts of which were excluded. For assessment of programme activities, we used information from the central IMCI data base, annual progress reports, follow-up after training visits and four studies on quality of c...

Methamphetamine (METH) is a potent inducer of dopamine (DA) release, and is toxic to DA neurons. It has been reported that the formation of free radicals is an early signaling event that mediates cell death caused by METH. Currently, studies suggest that the generation of free radicals by oxidative catabolism of DA and dysfunction of the mitochondrial respiration chain are important mediators of neuronal death in Parkinson&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s disease (PD) and one process may counter the effect of the other. In our previous study, we investigated the deleterious effects of METH-induced reactive oxygen species (ROS) and mitochondrial dysfunction in dopaminergic SK-N-SH cells in culture, and assessed whether zinc-metallothionein induction provided mitochondrial protection against METH-induced mitochondrial dysfunction. Our present data demonstrate that METH enhances lipid peroxidation and mitochondrial manganese superoxide dismutase (MnSOD) enzyme levels, and decreases the antioxidant-reduced glutathione (GSH) together with an inhibition of mitochondrial complex-I activity. Pre-treatment with zinc markedly prevents the increase of lipid peroxidation and provides mitochondrial protection by scavenging free radicals via metallothionein and by increasing mitochondrial GSH and complex-I levels, thus rescuing SK-N-SH cells from METH toxicity. It should be emphasized that, however, it is still not clear that effects of METH on cultured SK-N-SH reliably model the effects of METH in the intact animal. Further studies in the intact animal are needed.

A limitation of the ability to rotate the head with respect to the upper body has been associated with turning problems; however, the extent of head constraints on whole-body coordination has not been fully determined. The aim of this study was to limit head on body rotation and observe the effects on whole-body coordination during standing turns at various speeds. Twelve participants completed standing turns at 180°. A Vicon motion system and a BlueGain Electrooculography system were used to record movement kinematics and measure horizontal eye movements, respectively. All participants were tested at 3 randomized speeds, and under 2 conditions with or without their head constrained using a head, neck, and chest brace which restricted neck movement. A repeated-measures analysis of variance found a significant main effect of turning speed on the onset latency of all segments, peak head–thorax angular separation, and step characteristics. Constraining the head rotation had multiple si...

Insufficient warm-up (WU) of substitute soccer players could limit the performance and increase risk of injury. Different WU protocols were designed to help them get an effective WU in a shorter time frame for enhancing their performances. The aim of this study is to find a five-minute WU protocol that can improve flexibility and Repeated Sprint Ability (RSA) with an acceptable fatigue, as compared to no warm up condition. Twelve healthy collegiate male soccer players participated in this study. Subjects performed 4 randomly different warm up protocols on four nonconsecutive days: (a) no warm up (NW); rest of 5 minutes, (b) dynamic warm up (DW); jogging of 2:30 minutes and 2:30-minute of dynamic warm up, (c) dynamic resistance warm up (DRW); DW plus 8 repetitions of body weight squats, and (d) dynamic sprint warm up (DSW); DW plus two 20-m shuttle sprint.

Although aging population in Thailand is expected to increase rapidly, only one-sixteenth of the elderly engage in regularly physical exercise. Inactivity in ageing found to be associated with an increased incident of many chronic diseases such as hypertension, diabetes, Alzheimer's disease etc. Therefore performing regular exercise should recommend since it can exert its positive effect on the ageing’s physiological performance and brain functions. The purpose of this study was to investigate the acute effects of aerobic exercise by playing exergames on brain waves in sedentary elderly. Twenty volunteers aged 55 to 70 years (n=20; 10 male and 10 female) who did the exercise less than/equal two days per week and, no exergames experience. They were divided into two groups: control group (n=10) and exergames group (n=10). The exergames group was performed an aerobic exercise by playing exergames with moderate intensity (50% - 70% HRmax) for 20 minutes and recorded the EEG before a...

The purpose of this study was to compare the acute effect of cooling recovery method using cold water showers and sit in 15 °C temperature on core temperature (T c ), heart rate (HR) and thermal sensation scale (TSS) after exercise in hot environment. Nine subjects underwent 15 min of two recovery methods; sit in 15 °C room temperature (SIT15) and 15 °C water showers (CWS), after exercise at 65% O 2peak for 45 minutes in hot environment (35 °C room temperature, relative humidity (rh) 40-60%). Measures of HR, and T c were recorded every 30 minutes (min) throughout the experiment. TSS was obtained every 15 min until the end of the experimental trial. Results found that the values of T c and HR were not different between SIT15 and CWS methods after 15 min intervention period. The values of HR but not T c found to decrease at post intervention period ( p < 0.05) in both recovery methods. TSS was lower in SIT15 (-3; feeling cold) versus CWS (-2; feeling cool) ( p < 0.05).

This study was to assess the stress level and reaction time changes in the injured workers of the industrial rehabilitation center (IRC), social security officer, ministry of labor. Sixty workers (18 to 60 years) of age were participated in this study. They were divided into two groups: normal worker group (n=30) and injured worker group (n=30) Reaction time (visual, auditory and touch) and stress level (Suanprung Stress Test-60 (SPST – 60) were evaluated at the time of recruitment. Injured workers showed significantly decreased in the values of reaction time. Mean stress scores in SPST – 60 was significantly increased in this group compared to the normal group ( p <0.05). Stress level changes in work-related injured group indicate mental deconditioning after injury. Therefore, promoting effective performance and psychological well-being and self-efficacy in industrial rehabilitation program in injured workers would be help to reduce stress levels and prevent re-injury in this po...

Current restrictions on clinical visits as a consequence of the COVID-19 pandemic has increased the need for home-based exercise regimes to facilitate useful, long term patterns of behaviour in individuals with Parkinson’s disease (PD). This study aimed to evaluate the effectiveness of a 10-week home-based exercise program designed to target improvements in axial rigidity and gait. The Movement Disorders Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), motor scale and rigidity items, Functional axial rotation–physical (FAR-p), functional reach test (FRT), and time up and go (TUG) test were recorded. In addition, the 10-metre walk test, the fall efficacy scale international (FES-I) and the global rating of change score (GROC) were also recorded. Eighteen individuals were divided randomly into two groups: a home-based exercise group (n = 10) and a traditional physiotherapy control group (n = 8). Participants in the 10-week home-based exercise group showed significant impr...

We examined effects of a 20-min nap following 3 h of sleep deprivation on brain wave activity, auditory reaction time, the running-based anaerobic sprint test, leg muscle strength and the rating of perceived exertion in male college soccer players. Eleven players underwent three sleep conditions; normal sleep, sleep deprivation and 20-min nap after sleep deprivation. The sleep deprivation demonstrated an increase in the mean power of delta waves over the frontal area and a decrease in the mean power of alpha waves over the parietal area compared to the normal sleep. The nap and the sleep deprivation showed an increase in auditory reaction time compared with those in the normal sleep. The sleep deprivation demonstrated a decrease in the running-based anaerobic sprint test compared to the normal sleep, whereas the nap has partially reversed only minimal power and average power of the running-based anaerobic sprint test. The nap showed a recovery effect on leg muscle strength, but not ...

Camera-based 3D motion analysis systems are considered to be the gold standard for movement analysis. However, using such equipment in a clinical setting is prohibitive due to the expense and time-consuming nature of data collection and analysis. Therefore, Inertial Measurement Units (IMUs) have been suggested as an alternative to measure movement in clinical settings. One area which is both important and challenging is the assessment of turning kinematics in individuals with movement disorders. This study aimed to validate the use of IMUs in the measurement of turning kinematics in healthy adults compared to a camera-based 3D motion analysis system. Data were collected from twelve participants using a Vicon motion analysis system which were compared with data from four IMUs placed on the forehead, middle thorax, and feet in order to determine accuracy and reliability. The results demonstrated that the IMU sensors produced reliable kinematic measures and showed excellent reliability...
