Beyond the VO2 max: the role of self-belief in elite athletic performance
No full textIn the past Prof. Tim Noakes was convinced that physiology could explain performance. After 38 years of studying the human body, he now believes that the mind, and the role of self-belief, are crucial factors in human athletic feats. In January 2008, Noakes presented this lecture entitled “Beyond the VO2 max: The role of self-belief in elite athletic performance” at Croke Park Stadium, Dublin. This lecture explores how success in sports ranging from extreme cold water swimming to World Cup rugby are linked by a common thread - the role of self-belief
Series of lectures to the UCT rugby team
No full textIn the first lecture Prof Noakes speaks of the role of self belief in athletic performance ""what you really believe will happen is exactly what will happen"". The greatest hurdle is the mental barrier"". This trilogy of lectures was originally presented to the University of Cape Town's Rugby Team in 2008. The lectures centre around Prof Noakes' teachings of self belief and team unity as role players in athletic performance
Time to move beyond a brainless physiology
No full textAccording to Noakes, not enough people are looking at the bigger picture that the body does not function in discrete and unconnected apartments.He argues that too much of exercise physiology concentrates on the body’s reflexive automatic response to stimuli of shutting down close to the point of collapse. Exercise is a complex behavior that is regulated by a complex system. In this talk, Prof Noakes seeks to include the brain as a factor in exercise physiology. He starts with the classical teachings in exercise physiology and continues by looking at various models such as the A.V. Hill model and the peripheral model
2020 UPDATE on the Critical Report and Social Media Analysis About Emeritus Professor Timothy Noakes
No full textThis paper acts as a brief update on the events and postings of 2020 regarding anti-vaccine related misinformation online.
In a recent blog post, Tim Noakes continued to spread anti-vaccine misinformation and common anti-vaccine/vaccine hesitant tropes. Such misinformation included the flawed science done by anti-vaccine activist, Brian Hooker. This was used to defend Noakes’ 2014 social media post on Twitter that also included anti-vaccine misinformation (a video directed by Andrew Wakefield with the false autism-vaccine connection and CDC “coverup” conspiracy). He calls on Nathan Geffen, PhD to remove a previous article about him due to concerns about potential falsehoods, but Noakes has failed to do this with the very factual errors he has expressed and spread, which indeed can have public health consequences. Noakes also doubles down by implying support to the discredited, flawed paper by Andrew Wakefield.
Previously, Noakes’ social media had been assessed for not just what type of anti-vaccine misinformation was spread, but how much. This included observations of an increasing relationship between those who follow Noakes on Twitter, and those who also follow anti-vaccine accounts — this relationship has continued to increase dramatically in 2020. Noakes has continued to support several anti-vaccine leaders, such as Robert F. Kennedy Jr. and his organization Children’s Health Defense, and now recently Judy Mikovits and her documentary “Plandemic”. When assessing the overall vaccine narrative that Noakes broadcasts to his audience, it seems that 93% of it has been anti-vaccine in nature. Furthermore, in the first four months of 2020, Tim Noakes generated a maximum of ~7 million exposures to anti-vaccine misinformation. Across all tweets from August 2014 to May 7th, 2020, this number adds up to a staggering 11 million possible exposures. The claim that Noakes “is not anti-vaccine” and has not shared anti-vaccine misinformation is terribly weak and not based on the evidence.
Noakes has spread, expressed, and supported unscientific, disproven claims and the majority of what he has shared about vaccines is dangerous to public health and can cause harm to the reputation of those in his profession. Continuing to do so, as he has done, is a complete contradiction to what Noakes stands for, what others in his profession stand for, and what his own country’s regulatory body, as well as international organizations, stand for

The development of an evidenced-based submaximal cycle test designed to monitor and predict cycling performance : the Lamberts and Lambert submaximal cycle test (LSCT)
No full textIncludes abstract.Includes bibliographical references.The HIMS test, which consists of controlled exercise at increasing workloads, has been developed to monitor changes in training status and accumulative fatigue in athletes. As the workload can influence the day-to-day variation in heart rate, the exercise intensity which is associated with the highest sensitivity needs to be established with the goal of refining the interpretability of these heart rate measurements. The aim of the study was to determine the within subject day-to-day variation of submaximal and recovery heart rate in subjects who reached different exercise intensities

No full textUnderstanding and Quantifying Anti-Vaccine Misinformation Online: A Critical Report and Social Media Analysis About Emeritus Professor Timothy Noakes
No full textAlmost a fifth of South Africans fear that vaccines are unsafe. South Africa has indeed been a target of many anti-vaccination lobbying websites with claims and concerns regarding safety, the risk of adverse events, thimerosal, idiopathic illnesses including autism, and ‘vaccine-injured’ children. This seems to have contributed to the anti-immunization rumors and resistance within South Africa. Unfortunately, South African scientist, Timothy Noakes, has disseminated several expressions, claims, retweets, and re-publications about vaccines that are not based on truthful, accurate or up to date scientific information. This misinformation about vaccines that have been expressed, shared, and or spread can be deemed as irresponsible, unscientific, and a potential public health threat. Such information spread online can have and has had a major impact on critical thinking, vaccine acceptance, parental decisions, and even disease outbreaks. Upon analysis of Tim Noakes’ social media, there is a substantial amount of evidence for concern. From June to December 2019 there was a statistically significant increase in the number of followers Noakes gained that also aligned with anti-vaccine views. As for the content that Noakes himself has shared and expressed, 90% were Anti-Vaccine in nature, while only 10% were Pro-Vaccine. The potential maximum number of exposures to this anti-vaccine misinformation and rhetoric are in the millions, with approximately 3 million exposures in 2019 alone and 4 million in total from 2014 to 2019. The claim that Noakes has not shared anti-vaccine misinformation is terribly weak and not based on the evidence. Continuing to spread this misinformation is a complete contradiction to what Noakes stands for, what others in his profession stand for, and what his own country’s regulatory body, as well as international organizations, stand for.
This paper investigates common anti-vaccine misinformation shared by Tim Noakes and is also a social media analysis that covers anti-vaccine tropes and content. This paper also doubles as a literature review on the spread of misinformation in general, and more specifically, anti-vaccine misinformation. A separate section is dedicated to the topic of cancer misinformation which demonstrates the convergence between misleading cancer and vaccine ideologies.
The conclusions made in this paper are not all conclusive and there is room for flexibility — what is written is also meant to stimulate further input and discussion. Given the personal and emotive nature of the topic, it should be emphasized that what is written is with a non-malicious intent and should be perceived as in the interest of public health and online safety.
This case with Tim Noakes acts as a vehicle to highlight and learn more about several aspects of vaccine hesitancy, the anti-vaccine movement, social media, and misinformation in general
