Filter by:Climbing at high altitude and tolerating hypoxic environment require specific physiological adaptations. Large intersubjects differences exist regarding the ability to adapt to high altitude and hypoxia. The present study aims to characterise the physiological responses to hypoxia in a group of elite climbers by comparison to sea level athletes. We hypothesised that elite climbers would show better physiological responses to hypoxia and more preserved performances compared to sea level.
Introduction: The purpose of this study was to determine the effect of twelve weeks of aerobic exercise program on erythrocyte levels in women with breast cancer after chemotherapy. Methods: Thirty women with breast cancer after chemotherapy of Sydalshhda hospital (aged between 47-65 years) volunteered for this study, and then randomly selected an exercise (n = 15) and control (n = 15) groups. Exercise group completed a twelve-week aerobic exercise training program consisted of three sessions per week, each session lasting 30 to 60 minutes 50 to 75 percent of their maximum heart rate reserve, while the control group were followed. Blood samples including red blood cell counts (RBC), hematocrit (HCT), hemoglobin (HB), peak oxygen consumption before and after 12 weeks of aerobic exercise were measured. For analysis of data, repeated-measures analysis of variance (ANOVA) was used.
Chemotherapy-induced peripheral neurotoxicity (CIPN) as a side effect of chemotherapy negatively affects patients' quality of life and may lead to treatment disturbances. CIPN is frequently recorded in patients treated with alkylating platinum-based drugs, antitubulins including the taxanes and vinca alkaloids, and other drugs including suramin, thalidomide, lenalidomide and the proteasome inhibitor bortezomib, representing one of the most severe and potentially dose-limiting non-hematological toxic effects. Sufficient treatment options or preventive measures are lacking. There is evidence that physical activity strategies are able to address existing CIPN symptoms and potentially increase quality of life in affected patients. CIPN symptoms involves restrictions of sensory and sometimes motor modalities, for example, deficits in plantar perception and dysfunction of postural control and one study in type II diabetes patients also suggested that structured exercise might have a preventive potential with regard to peripheral neuropathy incidence. Based on these findings, we aim to investigate the preventive potential of a sensorimotor intervention vs. machine-based resistance training vs. usual care (wait-list control group) in a randomized controlled three-arm intervention trial among cancer patients undergoing chemotherapy with high risk for CIPN. On the basis of power calculations, the goal is to include 82 patients per intervention arm resulting in a total patients number to be enrolled of n=246. CIPN symptoms will be assessed objectively via comprehensive clinical and electrodiagnostic examinations (Total Neuropathy Scale; TNS-reduced) and subjectively via questionnaires (EORTC QLQ-CIPN20 & FACT-GOG-Ntx, EORTC QLQ-C30). Additionally CIPN and the effectiveness of the selected interventions will be objectively evaluated by spectral analysis of Centre of Pressure (COP) variations. Further key secondary endpoints are: physical performance, sleep quality and chemotherapy compliance.
The ketone body beta-hydroxybutyrate is produced during prolonged fasting or exercise and can be used as an alternative fuel source. Exogenous beta-hydroxybutyrate, in the form of a ketone salt, is proposed to have ergogenic potential for high-intensity exercise performance but this has not been adequately studied. The purpose of this study is to determine whether supplementing with an acute dose of ketone salts can alter fuel use during exercise and improve exercise performance.
The hypothesis of this study is that participation in the Retired and Senior Volunteer Program (RSVP) Bone Builders program 1 hour, twice per week, for 12 weeks may result in significant positive changes to the health status of older adult participants as demonstrated by increased leg strength and walking speed, improved balance and balance confidence, and enhanced life satisfaction. These improvements may lead to a reduction in risk of falls.
The objective of this study is to determine whether maintaining a eugonadal state, during severe, sustained energy deficit, attenuates physiological decrements, particularly the loss of lean body mass.
This study involves a randomized controlled trial to test the feasibility, acceptability, and efficacy of a mobile health (mHealth)-enhanced physical activity (PA) intervention to increase daily bout-related and total moderate-intensity PA and to reduce sedentary behavior (SB) in non-physically impaired patients with ischemic stroke or transient ischemic attack (TIA).
The purpose of this study is to determine how the modality of energy depletion can differently impact appetite hormones, ad libitum food intake, food hedonics, and olfaction.
Given the numerous physical and psychological benefits of engaging in regular physical activity (Biddle & Ekkekakis, 2005; Warburton et al., 2007) and the decrease in students' physical activity levels during the transition from high school to university (Bray & Born, 2010) it is important for researchers to develop time-and-cost-effective interventions to prevent this drop in physical activity. Intervention research shows mental contrasting (a goal setting strategy) can be taught in a cost-and-time-effective way in order to increase physical activity (Oettingen, 2012). Researchers have also found that individuals who consider the emotional effects of physical activity are more likely to be physically active than those who consider the health-related effects (Rhodes et al., 2009). The purpose of this research is to combine these two approaches to develop and evaluate a novel mental contrasting intervention to increase physical activity among a sample of undergraduate students.
The primary purpose is to evaluate the benefit of an education action of exercise on the level of physical activity in patients with knee osteoarthritis with the waning of a spa treatment for three weeks, three months after the start of the cure.
