OBJECTIVE: The authors studied weight gain mechanisms and energy balance in patients treated with olanzapine. METHOD: body mass index of male schizophrenic adolescent inpatients olanzapine (N=10) 10 matched haloperidol were measured at baseline after 4 weeks treatment. For the olanzapine, caloric intake, resting expenditure, physical activity (determined through accelerometry heart rate monitoring) assessed RESULTS: Body significantly increased those but not given haloperidol. increase was...

Background The transition from high school to university life is a critical time for change, often accompanied by the adoption of negative lifestyle habits including unhealthy nutrition. purpose this longitudinal study was identify sex-specific changes in dietary intake and diet quality, associated body weight composition during first-year university. Methods Three-hundred one students (n = 229 females) completed food frequency questionnaires, had their weight, composition, waist hip...

The processes of talent detection and early development are critical in any sport programme. However, not much is known about the appropriate strategies to be implemented during these processes, little scientific inquiry has been conducted this area. aim study was identify variables swimming, ball handling physical ability, as well game intelligence, which could assist selection process young water-polo players. Twenty-four players aged 14-15 years underwent a battery tests three times...

Testing for selection is one of the most important fundamentals in any multistep sport program. In ball games, coaches assess motor, physical, and technical skills on a regular basis early stages talent identification development. However, processes are complex, often unstructured, lack clear-cut theory-based knowledge. For example, little known about relevance testing process to final young prospects. The purpose this study was identify skill variables that could provide with relevant...

Muscle strength and activation were compared in boys men during maximal voluntary elbow flexion extension contractions. Peak torque, peak rate of torque development (dτ/dτ max ), muscle activation, electromechanical delay (EMD) measured 15 (aged 9.7 ± 1.6 years) 16 22.1 2.8 years). During flexion, was significantly lower than (19.5 5.8 vs. 68.5 11.0 Nm, respectively; p < 0.05), even when controlling for upper-arm cross-sectional area (CSA), electromyography activity. Boys also exhibited a...

Background. The use of insulin pumps is becoming a popular technique for delivery among patients with type 1 diabetes mellitus (T1DM), but there no consensus regarding the guidelines proper pump during exercise. Objective. To investigate physiologic responses and risk hypoglycemia children adolescents T1DM when exercising on (PO) (50% basal rate) or off (PF). Methods. Ten subjects (6 female 4 male subjects), 10 to 19 years age, performed prolonged exercise (40–45 minutes) cycle ergometer ∼2...

A mixed cross-sectional longitudinal design was used to study the effect of growth and physical maturation on peak aerobic anaerobic mechanical power. Subjects were divided into three groups based Tanner staging: 16 prepubertal (PP, Stage 1), 15 midpubertal (MP, Stages 2, 3, 4), 5 late pubertal (LP, 5). Aerobic power observed every 6 months for IS months. Peak oxygen consumption determined using a progressive cycle ergometer test. Anaerobic indices derived from Wingate Test. There no...

This study investigated the effects of caffeine supplementation on thermoregulation and body fluid balance during prolonged exercise in a thermoneutral environment (25 °C, 50% RH). Seven trained male subjects exercised treadmill at an intensity 70–75% maximal oxygen consumption to self-determined exhaustion. Subjects once after placebo ingestion, given double-blind crossover design. Five milligrams per kilogram weight followed by 2.5 mg∙kg −1 were 2 0.5 h before exercise, respectively....

The benefits and feasibility of progressive resistance training on muscle strength bleeding profile were studied prospectively in two patients with severe haemophilia. Additionally, retrospective data collected from three who had been for 11-21 years (one patient 21 11 years). Muscle increased, especially groups surrounding the target joints (elbow knee). Bleeding frequency decreased 2-3 times per week to 1-2 week. Patients > reported episodes 2-4 month prior training, but after a marked...

Sweating rate (SR) of boys is lower than that men. To assess the association between response individual sweat glands and physical growth maturation, three groups circumpubertal cycled at 50% VO2max in a climatic chamber (42 degrees C, 20% relative humidity). Based on Tanner staging (pubic hair), 16 were classified as prepubertal (PP, 1), 15 midpubertal (MP, 2-4), five late-pubertal (LP, 5). Population density (PD) heat-activated glands, mean area drops (DA), proportion skin covered by (%A)...

This study examined potential exercise-induced changes in sclerostin and bone turnover markers young women following two modes of high intensity interval exercise that involve impact (running) or no-impact (cycling). Healthy, recreationally active, females (n=20; 22.5±2.7 years) performed trials random order: running (HIIR) on a treadmill cycling (HIIC) cycle ergometer. Trials consisted eight 1 min intervals at ≥90% maximal heart rate, separated by passive recovery intervals. Blood samples...

The aim of this study was to determine whether age-related differences in the response cold exposure are due aging per se or caused by a reduced maximal oxygen uptake (VO2max) often observed with aging. Three groups men, 8 young adults (YA), well-trained seniors (TS), and 11 untrained (US), were tested on cycle ergometer thermoneutral (22 degrees C) (5 conditions during rest then exercise (approximately 50 W). In conditions, 10 min followed exercise. After 60 rest, subjects entered where 30...

Environmental heat is known to hamper aerobic performance. The purpose of this study was examine the effect on performance anaerobic exercise and recovery from such exercise. Eleven trained men underwent two identical exercise-recovery protocols in neutral (22 degrees C, N) hot (35 H) conditions, a cross-balanced order. Exercise consisted series five 15 s bouts separated by 30 active between bouts. 60 min resting evaluated with subsequent series. Subjects were kept euhydrated water. Peak...
