Study aim is determining the impact of a skill based intervention based on IMB model on Promoting School Teachers' Professional Competence in Teaching Sexual Health.
While the negative impact of sleep deprivation on cognitive processing and the partial reversal of this phenomenon by caffeine are well known, the types of cognitive processing previously studied have been limited to simple, straight-forward laboratory tasks. It is unclear how sleep deprivation and caffeine affect performance on operationally relevant complex cognitive tasks, like those encountered by working professionals such as doctors. This study aims to uncover how sleep deprivation and caffeine impact two types of clinical reasoning processes encountered by physicians on a daily basis. Previous work from members of our team investigated diagnostic reasoning in medical professionals and discovered that brain activation in executive processing areas was modulated by self-reported sleepiness and burnout and level of expertise (Durning, Costanzo, et al., 2013; Durning et al., 2014, 2015). The current study aims to expand upon those findings by also investigating a potentially more complex type of clinical reasoning, i.e. therapeutic reasoning, and directly manipulating sleep and caffeine use in a controlled sleep laboratory. Medical students, residents, and board-certified physicians will undergo thirty-seven hours of sleep deprivation and ten hours of sleep recovery in the sleep laboratory. During two FMRI scan sessions we will present high-quality validated multiple-choice questions on common patient situations in internal medicine to participants to explore brain activity during therapeutic reasoning compared with diagnostic reasoning. One FMRI scan will occur following a night of sleep deprivation, and another scan will occur following a night of recovery sleep. Additionally, half of the participants will receive caffeine gum during the sleep deprivation period, while the other half will receive placebo gum. This design will allow us to study the effect of sleep deprivation and caffeine on the neural correlates of diagnostic and therapeutic reasoning and performance in general.
The present project aims to investigate the acute and chronic effects of laser photobiomodulation (PBM) at 808 nm on muscle performance in physically active elderly women. The hypothesis of this study is that laser PBM would improve muscle strength (i.e., MVIC and 1RM) and endurance (i.e., repetitions-to-failure, blood lactate levels), functional capacity (i.e., short physical performance battery score), and rating of perceived exertion when compared with placebo laser.
In a double-blind, parallel randomized clinical trial with 38 cyclists in whom the performance improvement was determined after the consumption of docosahexaenoic acid for one month.
Aloe vera, sometimes described as pharmaceutical aloe, is a flowering succulent plant with many therapeutic properties such as wound and burn wound healing, treatment of diabetes and reduction of blood lipid profile. These benefits have been primary attributed to its high content in polysaccharides, anthraquinones and lectins. However, aloe vera includes more than 200 ingredients and nutrients (i.e. vitamins, saponins, amino acids, anthraquinones, minerals and trace-elements, salicylic acid, saccharides, lignin, enzymes, sterols) the combination of which offers more powerful effects and health-related benefits compared to each one of them separately. Thus, based on the ingredients and nutrients included, it has been proposed that aloe vera may also offer anti-inflammatory, antioxidative, analgesic and anabolic benefits. Exercise training, especially when it is unaccustomed or characterized by increased intensity, results in skeletal muscle microtrauma accompanied by elevated plasma levels of Creatine Kinase (CK), increased sensation of muscle soreness (DOMS), reduced force generating capacity and marked declines in speed and agility. Both anti-inflammatory and antioxidative mechanisms in skeletal muscle are crucial for the termination of inflammatory response and muscle healing process following exercise-induced aseptic muscle injury and inflammation. Although, it has been proposed that ale vera may elicit anti-inflammatory and antioxidative activity, its effectiveness in alleviating exercise-induced skeletal muscle injury and its symptoms, has not been investigated yet. Therefore, the aim of the present pilot study is to examine the effect of transdermal aloe veral delivery on skeletal muscle damage symptoms following an intense eccentric exercise protocol.
Background: Photobiomodulation has been explored for years, with wide clinical use for wound healing and analgesia in varied orthopedic conditions, but the number of research and clinical use has increased during the last decade. Furthermore, considering the performance, the current literature is conflicting and restricted, with divergences in wavelength, power and energy density applied. Therefore, analyze different doses for a answer in short and long time, associated with capacities of strength, fatigue resistance and functional performance of handball players and healthy individuals becomes necessary. Objective: To analyze the effects of the application of LED photobiomodulation on the capacities of strength, functional efficiency, temperature and fatigue resistance of handball players and healthy individuals. Method: The study sample will be composed of 56 male individuals randomly allocated into four groups: LED 50J (G-50J), LED 240J (G-240J), LED 50-240J (G-50-240J) - progressive dose and Sham (G-S). The volunteers will be submitted to an evaluation of muscle performance and functional performance, metabolic, and physiological evaluation. After initial tests, in five consecutive weeks, the LEDT (940nm - infrared) will be applied to the quadriceps femoris muscle and hamstrings, bilaterally, associated with a muscle strength protocol. After 24 hours of the last application TLED, the tests will be repeated. Seven days after the last intervention will be performed a follow-up. For analysis, normality tests will be used to verify the distribution and adequate statistical tests for the appropriate intra and intergroup comparisons, being considered two factors in the comparisons, time, and group. A significance level of 5% will be adopted.
This project aims to investigate if muscle strength and muscle power fluctuate during the menstrual cycle. The hypothesis is that the greatest performance will be measured right before ovulation, and at it's lowest on day 1 and 2 of the menstrual cycle in women not using any form for hormonal protection. And that the performance in women using birth control pills, not will variated in the period where they are taking pills (day 1-21).
This study assesses differences in biological and behavioral domains that relate to individual adaptation and resiliency to an isolated, confined and controlled environment, and evaluates the effect of confinement, work, monotony, and social and physical isolation on stress resiliency and well-being.
Observing a lack of research investigating the chronic physiological and psychological responses to this type of exercise training the aim of this study is to investigate the optimal training configurations of DoIT to produce positive effects on health, performance and quality of life markers in sedentary overweight or obese adults aged 30-55 years. The DoIT program will be performed in a small-group setting indoor or outdoor implementing a progressive manner for 12 months and using bodyweight exercises with alternative modes.
