Physiological Determinants of Exercise Performance

Description - summary of the module content

Module description

The principle objective of this module is to provide a detailed and critical review of the physiological factors that determine, and thus limit, exercise performance in humans. During the module you will analyse the factors related to peripheral and central fatigue that ultimately limit exercise performance across the duration-intensity spectrum. You will also critically examine the physiological mechanisms by which pacing strategies, ergogenic aids and training interventions (e.g., traditional aerobic or resistance based training, high-intensity interval training, and blood flow restriction) can lead to improved exercise performance. You will then evaluate how healthy ageing and disease may play a major role in exercise limitation in humans, before you explore the effect of extreme environments (e.g., heat, high-altitude and space) as well as the potential impact of sleep on exercise performance. You will also develop critical thinking skills in order to consider the weight of evidence behind certain interventions for the promotion of exercise performance. Specifically, you will learn to identify what is, and what is not, known regarding priming interventions for acute ergogenic benefit, and consider how to formulate and answer a pertinent research question in this field as part of your coursework. This summative work will also involve data handling, analysis, interpretation and dissemination. The Stage 2 module, Exercise Physiology (ESS2001) is a pre-requisite.

Module aims - intentions of the module

This module aims to develop your understanding of the key physiological determinants of exercise in healthy humans. The majority of material delivered in the lecture sessions will be research lead. That is, each lecture will provide a detailed and critical review of a factor (or factors) that affect performance in the context of the most relevant and recent scientific literature. Scheduled lectures may be replaced by short pre-recorded videos for each topic (i.e. 20 minutes) and/or brief overview lectures delivered via MS Teams/Zoom. Lecture material will be consolidated by self-directed learning resources and activities, as well as synchronous (“live”) seminars performed either online or in class where appropriate. The module will include at least one hour of synchronous teaching activities per week on average.

The module also has an applied focus and aims to provide a critical examination of how the theory matches the practice. In particular, the module aims to develop your critical thinking, data management and data analysis skills through your involvement in a series of seminars designed to guide you through the scientific research process from conception to completion.
.

On completion of this module you are expected gain and develop the following skills:

• Team work through involvement in the coursework seminar sessions and the formative assessment task
• Critical application of knowledge in the interpretation of data provided for the laboratory report (formative & summative assessment)
• Strategic thinking and problem solving in designing data collection.
• Build confidence as a communicator in discussing own experiments and scientific literature in seminar settings.
• Interpersonal skills in communicating with peers and module teaching team.
• Data management and analysis skills
• To effectively communicate complex physiological concepts through the writing of short scientific laboratory reports (formative and summative assessment)

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination. If you are successful on referral, your overall module mark will be capped at 40%.
