Filter by:Cranberry is a fruit native to North America that is widely grown in Quebec and has been shown to have the highest antioxidant capacity among the most commonly eaten fruits. Consequently, consuming cranberries prior to exercising may help to improve exercise endurance by preventing accumulation of reactive oxygen species. For aerobic endurance, in order to maintain a certain pace for a long duration, runners need to effectively neutralize reactive oxygen species. Although it is not the only component involved in running, offsetting reactive oxygen species should improve running performance. To test this, we plan to investigate the effects, both acute and chronic, of a cranberry extract on the oxygen consumption in 18-35 year old males and females. The present research project will contribute to expand our knowledge of how cranberry extract can exert a positive effect, and thus improve aerobic performance or even every day life. This project can benefit a wide range of the population, from sedentary individuals and older adults to elite athletes by providing an all-natural supplement alternative.
Primary Objective Characterizing precise functional capacity in surgical patients is critical for risk stratification and identification of patients at high risk for perioperative complications. The primary objective for the study is to evaluate the feasibility of effective subject recruitment of an FDA-approved simplified cardiopulmonary exercise testing apparatus in adults >60 years old prior to moderate to high-risk surgery. In addition, by development of a validation cohort of older adults, defined as >60 years old, self-reporting >4 METS and with a score of <2 on the revised cardiac risk index (RCRI)1 we will compare its effectiveness when compared to conventional preoperative evaluation measures (METS determination by standard scoring and Duke Activity Status Index) to SHAPE™ testing.
Rationale: The complication rate after pancreatic resection is high, especially in elderly and physically unfit patients. Aerobic capacity, as indicated by the ventilatory anaerobic threshold (VAT) assessed by a cardiopulmonary exercise test (CPET), can be used to identify high-risk patients. Previous studies have demonstrated that exercise prehabilitation can increase aerobic capacity in patients scheduled for intra-abdominal surgery, subsequently leading to better treatment outcomes. There is limited evidence on the feasibility of a (partly) supervised home-based prehabilitation program in patients scheduled for pancreatic resection. Objective: The primary objective of this study is to assess the feasibility of a four-week supervised home-based prehabilitation program in patients scheduled for elective pancreatic resection. Secondary objectives are to evaluate individual responses to prehabilitation on a number of secondary endpoints (no cause-effect relationship to be established). Study design: This study is a pragmatic multicenter study with a pretest-posttest design. It will take place at the Maastricht University Medical Center+ and University Medical Center Groningen in the Netherlands, and at the 'Città della Salute e della Scienza' in Torino, Italy. Study population: Patients planned for elective resection of a pancreatic tumor will be screened for potential eligibility. High-risk patients, identified by an oxygen uptake (VO2) at VAT ≤13 ml/kg/min and/or VO2peak ≤18 ml/kg/min, will be asked to participate. Intervention: A total of 45 patients will participate in a four-week (partly) supervised home-based personalized exercise training program before surgery (12 sessions in total). An advanced cycle ergometer (Lode Corival, Lode BV, Groningen, the Netherlands) will be delivered at the patient's home. Three weekly sessions of high-intensity interval training on the cycle will be combined with functional task exercise training. A trained physical therapist will visit the patient at least weekly to monitor progress. Main study parameters: The main study parameter is feasibility of the (partly) supervised home-based prehabilitation program. Hereto participation rate and reasons for non-participation will be evaluated. In participating patients, adherence/compliance, dropout rate, reasons for dropout, adverse events, patient motivation, and patient and therapist appreciation will be assessed throughout the program. Secondary endpoints: Secondary endpoints before and after prehabilitation include aerobic capacity, muscle function, body composition, functional mobility, immune system function, perceived fatigue, quality of life, and sarcopenia. Data on patient characteristics, neoadjuvant therapy, surgical procedure, and postoperative outcomes will also be collected for explorative purposes.
The study aims at assessing the influence of β-hydroxy-β-methylbutyrate (HMB) free acid supplementation (90 mg/kg of fat free body mass/day) supplemented for 21 days on protein kinases activity and selected hormones levels, and subsequent improvements in muscle protein synthesis, lean body mass content and aerobic capacity.
The aim of the proposed project is to investigate the reliability, validity, and usefulness of the 30-15 intermittent fitness test in the Slovenian Armed Forces. We will compare the results obtained from a continuous treadmill running test, 2-mile run test, and 30-15IFT.
Given the heightened cardiovascular disease (CVD) risk in post-menopausal women, studies are needed to explore novel, feasible methods for reducing risk in this population. Based on prior data, primarily in other populations, progressive resistance training is a promising candidate. This project will test the effectiveness of a practical, progressive resistance training regimen for lowering numerous CVD risk factors compared to both aerobic training and no exercise in post-menopausal women.
A randomized, double blind, counterbalanced, placebo controlled independent groups design. Participants will then be familiarized with the ergometer to determine settings and seating position and randomized to an investigational product group (2 groups: Aronox vs placebo; 1:1 allocation). A time to undergo baseline testing will then be scheduled (day 0). On the baseline day, stature, body mass, blood pressure and heart rate will be assessed. Participants will then complete a submaximal aerobic performance test (lactate profile) where expired gas, heart rate, blood lactate,and RPE will be measured. Following a 10-min rest, participants will then perform a ramp test to exhaustion to determine VO2max (this will be to finalize eligibility to the study - VO2max of 45-70 ml/kg/min). Expired gas, heart rate, power output, perceived exertion, and near-infra-red spectroscopy will be collected throughout and blood lactate will be determined at test termination. Those that do not fulfill the criteria for VO2max will be excluded from the study at this point. Those that are eligible (verified by their VO2max) will consume a standardized 'light' meal and rest for 2 h. Time to exhaustion (TTE) trial (60%GET) determined from previous tests (lactate profile and VO2max) will then be completed. On completion of the TTE trial, the first dose of the investigational product will be administered in the laboratory and participants will be given a 4-week supply of the investigational product to take in the morning with breakfast. Participants will also be given study diaries to complete (exercise, general health, dietary intake). On the final study day (day 28), remaining investigational capsules and study diaries will be collected to monitor compliance. An identical trial to day 0 will then be conducted, following which participants will be asked if they knew what supplement they were asked to consume and be given the chance to provide feedback on their experience.
