    Season 7, Episode 7 w Aaron Bezzina on Health and wellness in the Australian coal mining industry

    Season 7, Episode 7 w Aaron Bezzina on Health and wellness in the Australian coal mining industry

    In this episode, I meet with my new friend Aaron Bezzina. I found Aaron's latest research on LinkedIn and invited him on the podcast. Aaron is a PhD candidate at the University of Newcastle and an Accredited Practicing Dietitian (APD).  In 2020 Aaron commenced his PhD candidature at the University of Newcastle, researching workplace wellness initiatives' effects on health attitudes and behaviours within the Australian resource sector. Aaron’s research interests include workplace wellness and productivity, obesity, human factors, and occupational health and safety issues.

    This episode discusses Aaron's latest publication, a review on workplace wellness programs.

    Bezzina A, Ashton L, Watson T, James CL. Workplace wellness programs targeting weight outcomes in men: A scoping review. Obes Rev. 2022 Apr;23(4):e13410. doi: 10.1111/obr.13410. Epub 2022 Jan 25. PMID: 35076133.

    Then we go in-depth into one of Aaron's studies investigating health and wellness in mining. Aaron found that self-reported height and weight measures indicated that less than 20 percent (18.9%) of participants were in a healthy BMI range, while there were effectively equal numbers of overweight (40.9%) and obese (39.1%) participants. Only 3.5% of participants met the daily recommendation for vegetables (5 serves), and shift workers had a greater association with elevated BMI than non-shift workers. Poor nutrition is likely to be a key component in elevated levels of overweight and obesity within this industry, with workplace factors compounding challenges workers face in implementing health behaviour change. 

    Bezzina A, Austin EK, Watson T, Ashton L, James CL. Health and wellness in the Australian coal mining industry: A cross sectional analysis of baseline findings from the RESHAPE workplace wellness program. PLoS One. 2021 Jun 4;16(6):e0252802. doi: 10.1371/journal.pone.0252802. PMID: 34086829; PMCID: PMC8177661.

    And finally, we discuss this study on alcohol in Australian mining that Aaron was involved in that found metalliferous mining employees engage in at-risk levels of alcohol consumption significantly higher than the national average despite workplace policies.

    James CL, Tynan RJ, Bezzina AT, Rahman MM, Kelly BJ. Alcohol Consumption in the Australian Mining Industry: The Role of Workplace, Social, and Individual Factors. Workplace Health Saf. 2021 Sep;69(9):423-434. doi: 10.1177/21650799211005768. Epub 2021 Apr 24. PMID: 33896275.

    Season 7, Episode 6 Sleep loss and performance in female athletes with Liv Knowles

    In this episode, I speak to Liv Knowles about her research. Specifically, we discuss the lack of research in female athletes and why that may be. We also discuss the impact of sleep loss on physical performance and why your legs may give way before anything else. Check out some of Liv’s papers and writing.

    Combat Sports Series: Episode 3 w Dean Amasinger Technical Director UFC Performance Institute

    Combat Sports Series: Episode 3 w Dean Amasinger Technical Director UFC Performance Institute

    In this episode of the Combat Sports Series, I am joined by Dean Amasinger, Technical Director of the UFC Performance Institute in Shanghai China. Dean joins us today via a lockdown in Shanghai where he has chosen to stay lockdown within the Performance Institute. Dean is a former MMA fighter https://www.tapology.com/fightcenter/fighters/14113-dean-amasinger-renegade who competed in The Ultimate Fighter (TUF) with Team UK and returned as a coach in Team UK vs Team Australia. I had a lot of fun talking to Dean about his former training partners such as Michael Bisping, Dan Hardy, Paul Daley and many more. Dean also shared some insights from his time in the TUF house. Mainly Dean and I discussed the aspects of fighter development, skill acquisition, strength & conditioning, crossover from rugby to wrestling and to MMA and how to identify the archetype of a UFC competitor. This was a great conversation and a must listen to those interested in combat sports, however, there are some great crossover points here for anyone looking for self-development or improvement.
