Objectives. — Muscle oxygenation capacity is a metabolic component that can influence thebilateral strength asymmetry. This study measured the muscle oxygen saturation (SmO2) during aprotocol of high-intensity Results. — Greater average peak torque were found in the DL of the knee extensor muscles (DL:157 ± 28 vs. NDL: 148 ± 25; P = 0.028). Similarly, a SmO2difference (DL: 11.7 ± 10.1 vs. NDL:16.3 ± 13.2; P = 0...
Background: Body temperature is often assessed in the core and the skin. Infrared thermog- raphy has been used to measure skin temperature (Tsk) in sport research and clinical practice. This study aimed to explore the information reported to date on the use of infrared thermography to detect short-term Tsk responses to endurance exercise and to identify the methodological considerations and knowledge gaps, and ...
Although preliminary studies suggested sex-related differences in physiological responses to altitude/hypoxia, controlled studies from standardised exposures to normobaric hypoxia are largely lacking. Hence, the goals of this study were to provide information on cardiorespiratory responses to a 7-h normobaric hypoxia exposure and to explore potential differences between men and women. In this crossover study, a...
Objective: Anaerobic work capacity (AWC) is understood as the maximum power that the athlete can withstand over time, conditioned by high intensity effort and it is important to interpret it for the performance improvement. In addition, the muscle oxygen saturation (SmO 2) provides information on muscle metabolism and hemodynamics. Likewise, critical oxygenation (CO) is the highest metabolic rate that results i...
Passive and active hypoxia could be used as a tool during a transitional phase to maintain the effects of warm-up and optimize athletic performance. Our purpose was to evaluate and compare the effects of four different re-warm-up strategies, i.e. rest in normoxia (RN) at FiO2 = 20.9%, rest in hypoxia (RH) at FiO2 = 15%, active (5 minutes dryland-based exercise circuit) in normoxia (AN) and active in hypoxia (AH...
Moderate intermittent hypoxia (IH) protocols may help to restrain osteoclastic activity and/or stimulate osteoblastic activity. Therefore, whole-body vibration (WBV) combined with IH exposure may provide the most effective treatment for osteoporosis. The present randomised controlled trial investigated if normobaric IH exposure combined with WBV training over an 18-week period for the elderly is more effective ...
Abstract: Among other functions, hypoxia-inducible factor plays a critical role in bone–vascular coupling and bone formation. Studies have suggested that hypoxic conditioning could be a potential nonpharmacological strategy for treating skeletal diseases. However, there is no clear consensus regarding the bone metabolism response to hypoxia. Therefore, this review aims to examine the impact of di erent modes of...
Background Ageing is accompanied by a loss of muscle mass and function, which are associated with decrease of functional capacity. Combination of WBV training with normobaric hypoxic exposure could augment the beneficial effects due to synergic effects of both treatments. Aims The purpose of this study was to examine the effects of 36 sessions of the combined WBV training and normobaric hypoxic exposure on musc...
Therapeutic benefits of hypoxic training have been suggested for clinical populations, such as elderly who could suffer loss of lower limb muscle strength and higher risk of falling. This study investigated the effects of 18 weeks of whole-body vibration (WBV) training in normobaric hypoxia on the strength parameters of an elderly population. Thirty-one healthy elderly participants were randomly assigned to a h...
High intensity strength training causes changes in steroid hormone concentra- tions. This could be altered by the muscular contraction type: eccentric or concen- tric. The aim of this study was to compare the effect of the completion of a short con- centric (CON) and concentric/eccentric (CON/ECC) trial on the urinary steroid profile, both with the same total work. 18 males performed the trials on an isokinet- ...
