Stephan Geisler (* 4. April 1977) ist ein deutscher Sportwissenschaftler und Professor für Fitness und Gesundheit an der IST-Hochschule für Management in Düsseldorf. Er ist Vizepräsident für Forschung an der IST-Hochschule und Präsident der NSCA Germany (National Strength and Conditioning Association) und Gründer des Fitnesswissenschaftskongresses sowie des Deutschen Fitnesswissenschaftsrats.Website des Fitnesswissenschaftsrates
Leben Geisler studierte an der Deutschen Sporthochschule Köln Rehabilitation und Prävention. Seine Promotion befasste sich mit molekularen Mechanismen trainingsbedingter Anpassungen der Skelettmuskulatur, insbesondere mit Myostatin. Seit 2013 ist er Professor an der IST-Hochschule für Management.
Geislers Arbeitsgebiet umfasst Krafttraining und trainingsbedingte Anpassungen der Muskulatur. Er wirkte unter anderem an einer randomisierten Studie zu Krafttraining unter partieller Blutflussrestriktion mit. Die Studie verglich funktionelle und strukturelle Anpassungen mit einem konventionellen Krafttraining geringer Intensität.
Er ist Mitbegründer des Fitnesswissenschaftskongresses, der seit 2018 im zweijährigen Rhythmus stattfindet und nationale sowie internationale Größen der Fitnesswissenschaft zusammenbringt. Außerdem ist er Mitorganisator des Fitnesswissenschaftsrat, der zu wichtigen Forschungsthemen öffentliche Symposien abhält und Ratschläge für die Politik entwickelt.
