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 ]]> Blood lactate accumulation and clearance during typical training sessions in well-trained masters and young cyclists https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49900 0.05). Following both protocols, the masters cyclists exhibited a higher final blood lactate value (CON: d ± 90%CI = -0.97 ± 0.80, moderate; HIT: d = -0.70 ± 0.81, moderate) and a lower percent change (CON: d = -0.84 ± 0.87, moderate; HIT: d = -0.70 ± 0.85, moderate) during recovery. To mitigate any influence of masters athletes’ diminished blood lactate clearance, it is recommended that extra recovery time or active recovery strategies be used in masters athletes following exercise.]]> Wed 14 Jun 2023 12:00:48 AEST ]]> Hydration status of rugby union players in hot and humid conditions: a comparative team case study of day and night training sessions https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33308 2%. TSS increased significantly across both day (1.2±1.3; 5.2±1.0) and night sessions (1.4±1.0; 3.6±1.6). However, TSS was significantly higher post-training in the day session and players ingested more fluids during the day session (1.4±0.5; 0.9±0.4 L·hr⁻¹). Reduced thermal stress scores may compromise self-mediated hydration practices in rugby players when training at night and lead to greater body mass loss.]]> Mon 24 Aug 2020 17:28:45 AEST ]]> Autonomic cardiovascular modulation in masters and young cyclists following high-intensity interval training https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30785 60); ii) the time constant of the 30-min heart rate recovery curve (HRRτ); iii) the time course of the root mean square for successive 30-sec R–R interval (RMSSD30); and iv) time and frequency domain analyses of subsequent 5-min R–R interval segments. Results: No significant between-group differences were observed for HRR60 (P = 0.096) or HRRτ (P = 0.617). However, a significant interaction effect was found for RMSSD30 (P = 0.021), with the master cyclists showing higher RMSSD30 values following HIT. Similar results were observed in the time and frequency domain analyses with significant interaction effects found for the natural logarithm of the RMSSD (P = 0.008), normalised low-frequency power (P = 0.016) and natural logarithm of high-frequency power (P = 0.012). Conclusion: Following high-intensity interval training, master cyclists demonstrated greater post-exercise parasympathetic reactivation compared to young cyclists, indicating that physical training at older ages has significant effects on autonomic function.]]> Mon 23 Sep 2019 12:34:33 AEST ]]> Age-related changes in physical and perceptual markers of recovery following high-intensity interval cycle exercise https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43042 0.05). A significant reduction in 10SST peak power was found in both masters (P = 0.002) and young (P = 0.003) cyclists at 1 h post exercise, however, both groups physically recovered at similar rates. Neither group showed significant (P > 0.05) or practically meaningful increases in CK (%∆ < 10%). A significant age-related difference was found for perceptual fatigue (P = 0.01) and analysis of effect size (ES) showed that perceptual recovery was delayed with masters cyclists reporting lower motivation (ES ±90%CI = 0.69 ± 0.77, moderate), greater fatigue (ES = 0.75 ± 0.93, moderate) and muscle soreness (ES = 0.61 ± 0.70, moderate) after 48 h of recovery. Conclusion: The delay in perceived recovery may have negative effects on long-term participation to systematic training.]]> Mon 12 Sep 2022 12:31:25 AEST ]]> Amino acid distribution in blood following high-intensity interval exercise: a preliminary study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54752 Mon 11 Mar 2024 14:53:24 AEDT ]]> Validity of a contact mat and accelerometric system to assess countermovement jump from flight time https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47771 0.05), yet MT-derived measures were significantly different from those obtained using the FP (p < 0.05). Systematic bias was observed between FP and the CJ and between FP and MT. This study demonstrates the validity of CJ and MT systems for the assessment of CMJ height. Systematic bias and between-device differences in measurement should be considered when interpreting and comparing data from these devices.]]> Fri 27 Jan 2023 14:23:00 AEDT ]]>
