Investigating the key stress factors affecting cyclists in the urban area by analyzing self-reported data, physiological responses, cycling behaviors, and traffic conditions

Background Studies showed changes in the central nervous system in patients who sustained an anterior cruciate ligament tear. There is a lack of evidence regarding the effectiveness of transcranial direct-current stimulation in such patients. Methods A sham-controlled randomised study. One group of patients (n = 6) underwent 6 weeks of sensorimotor...

In weightlifting, quantitative kinematic analysis of an athlete can be useful for assessing performance during the snatch. A marker-based approach (MB) is widely used to obtain kinematic data in weightlifting. However, it is not suitable for field activities such as competitions. Recently developed markerless video-based systems (VB), which utilize...

Background: Since 1968, thousands of patients with a morphologically or functionally univentricular heart have been treated with a total cavopulmonary connection/Fontan operation. Because of the resulting passive pulmonary perfusion, blood flow is assisted by the pressure shift during respiration. Respiratory training is known to improve exercise...

Previous studies reported that both a more compliant quadriceps tendon and a stiffer Achilles tendon are associated with better running economy. While tendon stiffness can be decreased by a single bout of proprioceptive neuromuscular facilitation (PNF), post-stretching dynamic activities (PSA) can counteract the potential stretch-induced force loss...

Dried blood spots (DBS) are an alternative sampling method to blood plasma sampling. In contrast to blood plasma sampling, DBS are low-volume capillary blood samples obtained via pricking and collection on paper cards. DBS require less space and no cooling which is advantageous for exercise tests in the field. The aim of this project was to compare...

Purpose To determine the sensorimotor and clinical function of patients with confirmed successful outcome after either undergoing acromioclavicular joint (ACJ) stabilization, Bankart repair (BR), or rotator cuff repair (RC), and to compare these measures to the contralateral, healthy side without history of previous injuries or surgeries of the upp...

In high-intensity interval training the interval duration can be adjusted to optimize trainingresults in oxygen uptake, cardiac output, and local oxygen supply. This study aimed to compare thesevariables in two interval trainings (long intervals HIIT3m: 3 min work, 3 min active rest vs. shortintervals HIIT30s: 30 s work, 30 s active rest) at the sa...

Human metabolism is highly variable. At one end of the spectrum, defects of enzymes, transporters, and metabolic regulation result in metabolic diseases such as diabetes mellitus or inborn errors of metabolism. At the other end of the spectrum, favorable genetics and years of training combine to result in physiologically extreme forms of metabolism...

For several years, the detection of gait has been popularly implemented using wearable sensors, especially in the sports and medical areas. They are unobtrusive devices which allow to monitor individuals without the need of any ambulatory technology. Despite the fact, the optimal location of the sensor remains uncertain and dependent on the type of...

Introduction: Prior exercise, also known as “priming”, is suspected to affect the cardiovascular as well as muscular system (Jones, Koppo, & Burnley, 2003; Layec et al., 2009; Poole, Barstow, McDonough, & Jones, 2008). Many previous studies investigated metabolic processes that are affected by priming. But only a few studies referred prior exercise...

Introduction: As survival of previously considered as lethal congenital heart disease forms is the case in our days, issues regarding quality of life including sport and daily activities emerge. In patients with Fontan circulation, there is no pump to propel blood into the pulmonary arteries since the systemic veins are directly connected to the pu...

Effekt zweier Intervalltrainings auf das HHb/VO2-ratio Fabian Stöcker & Korbinian Ksoll Technische Universität München Schlüsselwörter: O2-Versorgung, Intervalltraining Einleitung Verbesserte mikrovaskuläre Sauerstoffverfügbarkeit ist vor allem während Belastungs-wechseln mit einer beschleunigten Sauerstoffaufnahme-Kinetik assoziiert. Um diese Ei...

After an active muscle stretch, maintaining a certain amount of force in the following isometric phase is accompanied by less muscle activation compared to an isometric contraction without preceding active stretch at the corresponding muscle length. This reduced muscle activation might be related to reduced metabolic costs, such as the oxidative me...

DOES MULTIDAY DIETARY NITRATE SUPPLEMENTATION HAVE AN ERGOGENIC EFFECT ON INTERMITTENT EXERCISE PERFORMANCE AND OXYGEN PARAMETERS? APPEL, K., HÄRTER, E., STÖCKER, F., SCHULZ, T. TECHNICAL UNIVERSITY MUNICH Introduction Dietary Nitrate (NO3-) supplementation has been reported to elicit many ergogenic effects in humans, for instance, to reduce the 02...

Blood flow (BF) in exercising muscles is an important factor for exercise capacity. Recently, a non-invasive method to estimate capillary BF (Qcap ) was introduced. Using this method, the Fick principle is re-arranged by using relative differences in deoxygenated haemoglobin (ΔHHb) as a surrogate for arteriovenous O2 difference and pulmonary oxygen...

Interval training evidentially triggers aerobic adaptions like improved fatty acid and carbohydrate oxidation rates. Increased local blood supply is supposed to be one important mechanism that underlies these effects. Two important determinants of interval training are intensity and duration of work intervals. However, knowledge is scarce on the de...

Background: Aerobic adaptations following interval training are supposed to be mediated by increased local blood supply. However, knowledge is scarce on the detailed relationship between exercise duration and local post-exercise blood supply and oxygen availability. This study aimed to examine the effect of five different exercise durations, rangi...

Increased local blood supply is thought to be one of the mechanisms underlying oxidative adaptations to interval training regimes. The relationship of exercise intensity with local blood supply and oxygen availability has not been sufficiently evaluated yet. The aim of this study was to examine the effect of six different intensities (40-90% peak o...
