    Purpose
    The present study was designed to evaluate the effects of aerobic and strength training on cardiac variables such as blood pressure, heart rate (HR), and metabolic parameters like cholesterol, high density lipoprotein (HDL), triglycerides and anthropometric parameters of obese women of Punjab.
    Methods
    This study was performed as an experimental study, in which subjects were randomly selected. There were thirty obese women, aged between 35-45yrs with body mass index (BMI) of above 30. Subjects were grouped into control (n=10), aerobic training (n=10) and resistance training (n=10). Aerobic training was given for three days a week at 60-70% of maximum HR for 6 weeks. Resistance training (Delorme and Watkins Technique) was given for alternate days for 6 weeks. HR and blood pressure were measured before and after the exercise. Recovery HR was also measured.
    Results
    The findings of the study indicate statistically significant differences in recovery heart rate [Pre-exercise: 97.40± 5.378 (mean ± standard deviation (SD)), post-exercise: 90.70±4.599, t=8.066, P<0.001] and in post-diastolic blood pressure [Pre-exercise: 85±3.265, post-exercise: 86.20±2.820, P<0.001] in aerobic training and in systolic blood pressure [Pre- and post-exercise] in both training groups (P<0.001). Significant differences were observed in very low-density lipoprotein [pre-exercise: 28.10±1.415, post-exercise: 26.86±0.760, t=5.378] and HDL [pre-exercise: 45.40±3.533, post-exercise: 53.60±3.134, t=6.318] levels in aerobic training group with P<0.001. BMI and body fat percentage showed significant improvements in both training groups.
    Conclusion
    Aerobic training is more beneficial and can be used as a preventive measure in patients who are at risk of developing cardiovascular diseases due to obesity.

    Purpose
    The present study investigated the psychometric properties of a Malaysian adapted Brunel Mood Scale.
    Methods
    The questionnaire was administered to 355 young sport athletes with a mean age of 14.69 + 1.70 years. Confirmatory factor analysis (CFA) and Cronbach's alpha were used to determine the factorial validity and the internal consistency of the questionnaire respectively.
    Results
    CFA results revealed adequate model fit, best represented by a 6-factor model with one of the items removed (item 24). Internal consistency of the questionnaire was marginally supported through alpha reliability method. Alpha coefficients of 0.72, 0.64, 0.73, 0.69, 0.65, and 0.58 were obtained for tension, depression, anger, vigour, fatigue and confusion subscales respectively. Closer inspection of items for confusion revealed a ‘problematic' item (item 24/uncertain). Removing this item increased the alpha coefficient to 0.67 for this subscale.
    Conclusion
    It was concluded that this questionnaire may be used to measure differentiated negative and positive mood states among Malaysian adolescent athletes. However, further analyses involving independent samples are needed to confirm the present findings.

    Purpose
    The aim of this study was to investigate the relationship between perception of emotional intelligence and beliefs in the extent to which exercising leads to mood-enhancement.
    Methods
    Volunteer participants (N= 315) completed a 33-item self-report measure of trait emotional intelligence and an exercise-mood regulation scale.
    Results
    Emotional intelligence significantly correlated with beliefs that exercise could be used to regulate mood (r =0.45, P<0. 01).
    Conclusion
    Findings demonstrate that using exercise to regulate mood relates significantly to emotional intelligence and suggest that individuals who use exercise to enhance mood report higher scores of emotional intelligence.

    Purpose
    Despite numerous studies which have been done regarding soccer injuries worldwide, there is lack of available data considering the epidemiology of injuries in the Iranian soccer premier league, although it is the most popular sport in the country. The main goal of this research was to determine the incidence of physical injuries in the studied population, considering other characteristics such as site, type and mechanism as well.
    Methods
    Twenty one adult male professional soccer players (age 24±3), members of a team (Tehran-Pas) participating in Iranian premier league, were followed during a 4-month period. The injury characteristics and exposure times were recorded by the team physician during all the matches and training sessions.
    Results
    The total exposure time was 2610 playing hours (2352 h of training versus 258 h of competition). Eighty six percent of the injuries were acute. Incidence of acute injuries was 16.5 (95% CI: 12-22) per 1000 hours of playing (11.5 per 1000 hrs of training and 62 per 1000 hrs of competition). The most common types of injuries were strains followed by contusions, each of which constituted 30% of acute injuries. More than 80% of injuries occurred in lower limbs, especially in thigh and groin regions. Nearly 60% of acute injuries occurred in dominant side of the body, and collision was the reason of about half of the acute injuries. Severity of more than 70% of the injuries was minor. On average each injury had led the player being off the field for about 10 days.
    Conclusion
    The incidence of injury in this research is in range of numbers obtained in important international tournaments but the rate of injuries during training sessions is higher than comparable studies.

    Purpose
    This study was conducted to investigate risk factors of obesity and its associated health problems in adolescence in Taiwan.
    Methods
    We enrolled 559 adolescent volunteers with equal numbers of females and males in 2008. Participants were divided into two groups: obese (body mass index [BMI] ≧95th percentile) and normal-weight adolescents (BMI: 15th ~ 85th percentile). Each of them completed a questionnaire about lifestyle and parent's stature.
    Results
    Obese mother had high likelihood of having obese girls and boys (P=0.001). Obese girls spent more time in watching TV (P=0.03) and had a higher frequency of having sweetened soft drinks (P=0.016) than normal-weight group. Spending more time in watching TV by girls was associated with a higher frequency of having sweetened soft drinks (P=0.012). In boys, it was associated with higher frequency of eating snack (P=0.018) and larger waist circumference (P=0.011). Boys who had more frequent effective exercise had lower frequency of eating outside (P=0.01) and more services of vegetables (P=0.002). There was no relation between hypertension and adolescent physical activity. Regardless of gender, obese group had higher waist circumference and blood pressure than normal-weight group (P<0.001).
    Conclusion
    There was a strong association between obesity of mother and adolescent obesity. More physical activity in adolescents is associated with healthier dietary behaviors. Obese adolescents have higher waist circumference and blood pressure.

    Background
    Athletes present a different category of the population. Trivial complaints may mask more serious illness, especially when the athlete is undergoing intensive training, and the function of his immune system may be sub-optimal.
    Case Presentation
    A triathlete presented a few days after completing an Ironman race, complaining of lethargy, pleuritic chest pain and loss of appetite. On examination he was afebrile, tachycardic and had decreased lower left lung air entry accompanied by crackling. A chest x-ray revealed left-sided basal pneumonia with a para-pneumonic effusion. Blood tests were unremarkable. The athlete was treated with oral antibiotics, and was advised to stop exercise completely for eight weeks. He made a full recovery and completed further Ironman races within a year.
    Conclusion
    The case highlights that clinicians treating elite endurance athletes must exclude severe infection, even when the clinical signs are few or absent. The reason is that if these athletes continue to train, serious complications could ensue due to their compromised resistance to infection.
