Furthermore, no interaction or between-group differences were evident for RPE across either session (P > .05). Conclusions: HR and RPE values were comparable between masters and young cyclists when relative HR responses and HR training load models are used. This finding suggests HR and RPE methods used to monitor or prescribe training load can be used interchangeably between masters and young athletes irrespective of chronological age.]]> Wed 28 Jul 2021 15:32:45 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42510 0.05). High ratings of participant satisfaction (4.73), enjoyment (4.54) and perceived value (4.54) were observed. Conclusion: This study demonstrates the efficacy and feasibility of delivering a novel HIIT program in the university setting.]]> Wed 24 Aug 2022 09:46:23 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45952 Wed 13 Mar 2024 14:13:52 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25481 Wed 04 Sep 2019 10:18:46 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32862 IFT) within rugby league. Sixty-three Australian elite and junior-elite rugby league players (22.5 ± 4.5 years, 96.1 ± 9.5 kg, Σ7 skinfolds: 71.0 ± 18.7 mm) from a professional club participated in this study. Players were assessed for anthropometry (body mass, Σ7 skinfolds, lean mass index), prolonged high-intensity intermittent running (PHIR; measured by 30-15_IFT), predicted aerobic capacity (MSFT) and power (AAS), speed (40 m sprint), repeated sprint, and change of direction (COD—505 agility test) ability before and after an 11-week preseason training period. Validity of the 30-15_IFT was established using Pearson’s coefficient correlations. Forward stepwise regression model identified the fewest variables that could predict individual final velocity (V_IFT) and change within 30-15_IFT performance. Significant correlations between V_IFT and Σ7 skinfolds, repeated sprint decrement, VO₂max_MSFT, and average aerobic speed were observed. A total of 71.8% of the adjusted variance in 30-15_IFT performance was explained using a 4-step best fit model (VO₂max_MSFT, 61.4%; average aerobic speed, 4.7%; maximal velocity, 4.1%; lean mass index, 1.6%). Across the training period, 25% of the variance was accounted by ΔVO₂max_MSFT (R² = 0.25). These relationships suggest that the 30-15_IFT is a valid test of PHIR within rugby league. Poor correlations were observed with measures of acceleration, speed, and COD. These findings demonstrate that although the 30-15_IFT is a valid measure of PHIR, it also simultaneously examines various physiological capacities that differ between sporting cohorts.]]> Tue 31 Jul 2018 11:55:18 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30651 Thu 28 Oct 2021 12:35:58 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32782 Mon 23 Sep 2019 14:01:33 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54770 Mon 11 Mar 2024 15:08:40 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44190 2peak]); ii) MICT (45min of cycling at 60% VO_2peak); or PLA. Training groups exercised thrice weekly for 12 weeks. Central arterial stiffness, hemodynamics and CVD risk factors were assessed at baseline and post-intervention. Analysis of covariance (ANCOVA) was used to examine changes following HIIT, MICT and PLA. Results: Thirty-five participants (age: 55.1 ± 1.4 years, BMI: 36.1 ± 0.8 kg/m²) completed the study. A significant intervention effect was found for changes in pulse wave velocity (PWV) (p = .03), which reduced with HIIT (−0.3 ± 0.9 m/s) and MICT (−0.1 ± 1.1 m/s) but increased with PLA (0.8 ± 1.6 m/s). There was a significant intervention effect for changes in V̇O_2peak (p < .01), glycosylated hemoglobin (p = .03), systolic blood pressure (p b .01), and waist circumference (p = .03), which all improved following MICT or HIIT but not PLA; there was no difference between MICT and HIIT. Conclusions: Twelve minutes of low-volumeHIIT perweek leads to improvements in central arterial stiffness and cardiovascular health in inactive individuals with obesity and T2D.]]> Mon 10 Oct 2022 11:02:37 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53659 Fri 15 Dec 2023 11:06:40 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33351 Fri 03 Dec 2021 10:31:58 AEDT ]]>
