No health problems in the narrow sense are being investigated. The short-term effects of exercise on a (neuro)physiological level are being investigated.

| The aim of the study is to investigate the influence of the type, duration, and frequency of short breaks from sitting on cognitive performance, mental well-being, and physiological and neurophysiological functions during sedentary office work. Three types of breaks—passive (PAN), a longer active break (PAL), and several short active breaks (PAS)—are examined in a simulated working day. Physical activity will take place on a medical treadmill. Subjective assessments (e.g., perceived mental load, stress level, mental fatigue), behavioral performance (reaction time, accuracy), and physical parameters will be recorded. The latter include cardiovascular activity (heart rate variability), muscular load (e.g., muscle activity, fatigue indicators), and neurophysiological responses (e.g., mental load, mental fatigue indicators, attention). These physiological parameters are collected using objective measurement methods such as electroencephalographie (EEG), electrocardiographie (ECG), and electromyography (EMG). The aim is to provide scientific evidence for work design prevention measures and practical recommendations for the design of exercise breaks during sedentary screen work. Measurement methods and questionnaires used: - Electroencephalography - Electrocardiography - Electromyography and myotonia measurement - NASA-TLX - Affect Grid - Energy Scale - Borg RPE - Sociodemographic questionnaire + questions on lifestyle/health/health behavior - Global Physical Activity Questionnaire (WHO) - Occupational Sitting and Physical Activity Questionnaire (OSPAQ) - Questionnaire for the analysis of stress-relevant task coping (FABA) | — |
