Filter by:Aim: The aim of the study is to investigate the effects of Reformer Pilates exercises in overweight and obese woman. Method: 47 sedentary overweight and obese women aged 30-60 years will be included in the study. Subjects will be divided into two groups: Reformer Pilates and control. The exercise group will be given Reformer Pilates training session 3 times a week over an 8-weeks period. Before and after the study, the subjects will be test for body composition with the bioelectrical impedance and for upper limb strength with the hand grip dynamometer. Moreover, the strength of the back muscle will be measure with the back dynamometer and the strength of the abdominal muscle with the sit-up test. Furthermore, the endurance of trunk, abdominal and back muscles will be measure with the McGill endurance tests. The endurance of the lower limb will be measure with the 30 second sit and stand test, and the balance with the Fullerton Advanced Balance Scale. Finally, the sleep quality will be measure with the Pittsburgh Sleep Quality Index, and the anxiety with the Hospital Anxiety and Depression Scale.
Standard risk prediction models in cardiac surgery (such as EuroSCORE II or STS score) are designed to analyze solely the risk of short-term postoperative mortality. The postoperative morbidity, the ability to rehabilitate or the mid-term survival are not addressed by these means. Recently there have been some reports that addition of physical performance testing to the standard prediction models may provide prognostic value. There is a wide scale of various physical performance and frailty tests that could be used for this purpose, but they have not been confronted with each other yet. Moreover, the postoperative physical rehabilitation has not been objectively assessed in larger scale despite the significant improvement in technology. The hypothesisis of the study is that the preoperative outcomes of physical performance and frailty testing are able to predict the patient's reconvalescence after cardiac surgery in the short- and mid-term postoperatively. The aim is to analyze a set of tests with regard to their ability to predict postoperative reconvalescence, including the objective activity assessment (using Actigraph wGT3X-BT activity tracking device). Secondarily, the investigators aim to follow the patients up to 1 year postoperatively in terms of evaluating their mid-term outcomes.
Negative hematological adaptations due to prolonged periods of strenuous physical activity may, in part, contribute to declines in physical performance during military operations. Exogenous erythropoietin (EPO) is a potential intervention that may be used to maintain hemoglobin (hgb), hematocrit (Hct), and physical performance during periods of high physical activity. The objective of the current study is to determine the ability of EPO to maintain hgb, Hct, and physical performance compared to baseline measures. Additionally, EPO may result in non-hematological adaptations which increase mitochondria biogenesis and alter substrate oxidation. As such, this study will also assess the influence of EPO on whole-body and skeletal muscle substrate oxidation. Eight healthy physically active individuals will be recruited to participate in this longitudinal trial. After exercise practice sessions, volunteers will complete baseline physical performance (time trial) and substrate oxidation testing. Participants will then receive EPO injections 3 times per week for 4 weeks. Diet and exercise will be controlled during the injection period. Participants will undergo four weeks of an intense physical training exercise program. Every seventh day during the injection period a safety blood sample, assessing hematocrit, will be drawn, and participants will complete a 5 km time trial to determine the time course of changes in physical performance can be detected. After the 4 weeks of EPO injections volunteers will complete the same physical performance and substrate oxidation testing. Substrate oxidation will be assessed during 90-min steady-state load carriage (30% body mass) exercise on a treadmill at 55 ± 5% of VO2peak. 6-6-[2H2] glucose tracer technique and indirect calorimetry will be used measure substrate oxidation. Muscle biopsies will be performed to measure muscle glycogen, enzyme activity, and molecular markers of metabolism and inflammation before, and immediately and 3-hrs post exercise. Multiple blood samples will be collected throughout the study to determine alterations in hemoglobin, hematocrit, and markers of substrate metabolism, and inflammation. All study procedures will occur at USARIEM. The primary risks associated with this study include those associated with EPO injection, exercise, blood draws, and muscle biopsies.
The primary objective is to assess the impact of two nutritional interventions vs. placebo on objective and subjective sleep measures in athletes. Participants receive one beverage on each of three consecutive nights in a randomized manner. It is hypothesized the two nutritional interventions will result in significant improvements in sleep onset latency, and will not result in a negative impact on next-day cycling performance. The secondary objective is to assess the impact of the nutritional interventions vs. placebo on next-morning performance (physical, cognitive function, and balance).
The aim of the study is to investigate the effect of ski sport on physical performance, pain, and quality of life compared to sedentary individuals of similar age groups and to examine the existence of gender-specific differences.
Brain-Physical Optimization Conditioning (B-POC) aims to enhance physical performance by expanding the traditional focus of endurance training from purely physical training to the domain of cognitive endurance (Staiano et al., 2015; Dallaway et al., 2017). The current study seeks to isolate neurocognitive mechanisms of performance, particularly under high stress (e.g., physical or cognitive load) conditions, and to develop corresponding cognitive optimization tools.
Exercise-based fall prevention programmes with strength and balance components have been shown to reduce the rate of falls, risk of falling, fractures and injuries. However, there is little evidence on the implementation of these programmes in real-world settings. This study aims to assess the effectiveness of exercise-based fall prevention interventions on fall risk (physical performance and fear of falling) among community-dwelling older adults who are at risk of falling in Singapore. A secondary aim is to assess the effectiveness of the programme on other health outcomes. The study will also evaluate the programme implementation from 3 perspectives of older adults, implementers and community partners.
Our study was conducted to compare the physical performances of the upper extremity and lower extremity of handball players according to the positions they played. In this cross-sectional study, a total of 39 elite female handball players with at least of 5 years playing experience were tested.Maximal voluntary isometric (MVIC) knee flexion and extension strength were measured using a handheld dynamometer (HDD) (Lafayette Instrument Company, Lafayette, IN). Lower extremity vertical power was identified through the use of the VertiMetric (Lafayette Instrument Company, Lafayette, IN) according to protocols suggested by Ambegaonkar et al. Trunk extension endurance was measured using the Biering-Sorensen test as previously described.The Davies test (DT) was used to assess upper body agility and stabilization.The Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) was utilized to assess shoulder performance function and stability according to protocol suggested by Goldbeck and Davies.The Shark Skill Test (SST) was developed in order to assess lower extremity agility and neuromuscular control.
During military action there might be situations where civil requirements for blood transfusion are not obtainable. Numerous warfare experiences suggest that administration of whole blood to a patient with uncontrollable bleeding/bleeding shock will improve survival in case of delayed evacuation. Among Norwegian troops this gives one of two choices: 1. A soldier donates blood to a wounded fellow soldier 2. Personnel in safe distance donates blood and it is transported to the frontline. Alternative b might implicate frequent donations and unused blood must be auto-re-transfused. This study will investigate: 1. Can 'buddy transfusion' in the field be justified also in medical aspects? 2. Can repeated donations and auto-transfusions of transported whole blood into personnel(X) be justified also in medical aspects? (X) Blood typed and screened for HIV, HBV, HCV, Syphilis before assignment
