Abstract Introduction The sport of cycling has witnessed phenomenal growth over the past decade. Globally, over 200 million television hours across five continents watched the recent inaugural World Championships in Glasgow, in 2023. The Union Cycliste Internationale (UCI), the world cycling governing body, has highlighted its mission to “promote and support research in cycling epidemiology and medicine, especially for the benefit of lesser-known disciplines” within its 2030 Agenda. This systematic review aims to comprehensively analyse and synthesize the existing literature about cycling-related injuries and illness across all competitive disciplines. Methods The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines will be followed through each stage of this systematic review. Cycling is an umbrella term used for many individual disciplines. Investigation of all types of injuries and/or illnesses sustained during training and/or competition among competitive athletes across all disciplines will be included in this review. A computerised, systematic literature search will be conducted in electronic databases MEDLINE, Scopus, Embase, and Cochrane Library. Independent screening by two reviewers in a two-step process: title/abstract screening followed by full-text review. The reference lists of included articles will be searched to identify any other potentially relevant articles. Narrative synthesis as well as tabular/charted presentation of the extracted data will be included. Discussion This will be the first systematic review of injuries and illness across all the cycling disciplines and will aim to present the known prevalence, incidences, locations and burden of injury and illness across the sport of cycling. Ethics and dissemination This paper outlines a protocol for a systematic review and meta-analysis. Since it does not involve human participants, ethical approval is not necessary. The intention is to disseminate the findings through a peer-reviewed journal and present them at a conference as well as meetings with key stakeholders, including cyclists themselves. Trial registration This study has been registered with the PROSPERO International Prospective Register of Systematic Reviews (registration number CRD42024502703)

Zusammenfassung Im Rahmen dieses Beitrags, der auf der gleichnamigen Bachelorarbeit des Erstautors beruht, wurden fünf Hauwerksanordnungen im Labormaßstab (1:25) hergestellt und unter wechselnden Bedingungen untersucht, ob nach der Neuanordnung des Hauwerks signifikante Abweichungen zwischen der Korngrößenverteilung aus der Siebanalyse und der Software BMX Fragmenter feststellbar sind. Die Bildserien für die photogrammetrische Hauwerksanalyse wurden mit einer Digitalkamera aus der Vogelperspektive und mit einer Smartphone-Kamera aus terrestrischen Positionen aufgenommen. Da die Software den Untergrund des Versuchsaufbaus als Feinanteil identifizierte, wurden die Auswertungen ohne Feinanteil durchgeführt. Die Ergebnisse zeigen, dass die Korngrößenverteilungen aus der Software unter gleichen Bedingungen ähnliche Kurvenverläufe aufweisen, jedoch mit zunehmendem Massendurchgang der Siebkurve zu kleineren Korngrößen tendieren. Hauwerksanalysen ohne punktuelle Lichtquelle tendieren im Vergleich zu Analysen mit punktueller Lichtquelle zu kleineren Korngrößen. Eine Bildserie mit befeuchtetem Hauwerk wurde aufgenommen, ausgewertet und mit den Ergebnissen der trockenen Probe verglichen. Dieser Vergleich zeigt, dass die Ergebnisse des befeuchteten Hauwerks zu kleineren Korngrößen tendieren. Die Auswertung der terrestrischen Aufnahmepositionen ohne Feinanteil liefert genügend Informationen, um eine Korngrößenverteilung zu erstellen, die der Korngrößenverteilung aus der Vogelperspektive entspricht. Da die Software einzelne Körner in mehrere Fragmente teilt, mehrere Körner zu einem Fragment zusammenfasst oder Körner, die größer als die Ground Sample Distance sind, als Feinanteil identifiziert, ist eine manuelle Nachbearbeitung der Fragmentanalyse, insbesondere bei Knäppern, notwendig. Zusammenfassend bietet die Software BMX Fragmenter die Grundlage für die rasche Erstellung einer Korngrößenverteilung, jedoch wird eine kritische Betrachtung sowie manuelle Nachbearbeitung der Fragment-Analyse empfohlen.
