EXSS2028: Exercise Physiology and Biochemistry

Semester 1, 2020 [Normal day] - Cumberland, Sydney

This unit discusses the acute responses to exercise with a specific emphasis on the roles of the respiratory and cardiovascular systems in oxygen transport and the significance of sub-maximal and maximal oxygen consumption in the limitations to performance. The concepts of acid-base balance during exercise and of lactate and ventilatory thresholds will be examined. Furthermore, this unit develops an understanding of the specific metabolic response to exercise at the peripheral cellular level and the biochemical strategies that maintain energy balance during exercise and a return to homeostasis in recovery. Students will put theory into practice with laboratory tasks that encourage skill acquisition in the collection of real-time physiological data of the respiratory and cardiovascular response to exercise.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

Attendance: You are expected to attend all lectures although during these sessions, attendance will not be graded. Tutorial attendance will be marked at every session. You are expected to attend these. Practical attendance will be marked at every session. You are required to attend these. While there is no grade provided for attendance, absences will be kept on record in the event of an external audit.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

This section outlines changes made to this unit following staff and student reviews.

Students have previously reported the take home tests to require more time than estimated. As such, in 2020 the take home test questions will be modified to more closely resemble student expectations. Prior to 2019 the unit was delivered in two distinct modules. 6 weeks of physiology and 6 weeks of Biochemistry separated by a Mid-Semester exam. In 2019, we trialled delivering the unit as a more integrated module of physiology and biochemistry and have further refined this delivery for 2020. In 2019, the rate at which feedback was provided for the take home tests was too slow. In 2020 we have been able to secure more staff for this unit to assist in grading assessments and delivering more rapid turn around.

Work, health and safety

In our practical classes, some students will be expected to perform exercise to exhaustion while others will be responsible for handling biological tissue such as saliva, sweat and blood (finger prick sampling). 

All protective gear including gloves, goggles and aprons will be provided to students tasked with sampling.

An induction for all safe procedures will be performed during respective practical classes.
