PURPOSE: To describe the training demands of contemporary dance and determine the validity of using the session-RPE (sRPE) method to monitor exercise intensity and training load in this activity. In addition, we examined the contribution of training (i.e. accelerometry and heart rate) and non-training related factors (i.e. sleep and wellness) to perceived exertion during dance training. METHODS: Training load and actigraphy for sixteen elite amateur contemporary dancers were collected during a 49 day period, using heart rate monitors, accelerometry and sRPE. Within-individual correlation analysis was used to determine relationships between sRPE and several other measures of training intensity and load. Stepwise multiple regressions were used to determine a predictive equation to estimate sRPE during dance training. RESULTS: Average weekly training load was 4283 ±2442 AU, monotony 2.13 ±0.92 AU, strain 10677± 9438 AU, and average weekly vector magnitude load 1809707 ±1015402 AU. There were large-to-very large within-individual correlations between sRPE-TL and various other internal and external measures of intensity and load. The stepwise multiple regression analysis also revealed that 49.7% of the adjusted variance in sRPE-TL was explained by HRpeak, METs, soreness, motivation and sleep quality (Y = -4.637 + 13.817 %HRpeak + 0.316 METS + 0.100 soreness + 0.116 motivation - 0.204 sleep quality). CONCLUSION: The current findings demonstrate; the validity of the sRPE method for quantifying training load in dance, that dancers undertake very high training loads and a combination of training and non-training factors contribute to perceived exertion in dance training.

The purpose of this investigation was to compare the criterion validity and test-retest reliability of common methods for quantifying training load. Ten (5 men and 5 women) recreational athletes (mean ± SD, V[Combining Dot Above]O2max: 37.0 ± 4.3 ml·kg·min; age: 23.8 ± 8.4 years) completed 18 randomly assigned steady state (SS) and interval (INT) training sessions during a 6-week period. Steady-state sessions were 18 minutes in duration and were performed at 35, 50, and 65% of maximum work capacity (Wmax). Interval sessions were performed at 50, 60, and 70% of Wmax with a work to rest ratio of 1:1 and matched for total work with the 50% SS session. Oxygen consumption (V[Combining Dot Above]O2) and heart rate (HR) were measured throughout all sessions, whereas blood lactate concentration and rating of perceived exertion (RPE) measures were taken every 6 minutes during sessions. Session-RPE (sRPE) was collected after each exercise bout. All individual correlations between V[Combining Dot Above]O2 and external work (r = 0.88-0.97), HR (r = 0.65-0.90), and RPE-based methods (r = 0.55-0.89) were statistically significant. External work correlated best with the total V[Combining Dot Above]O2 and was significantly different from RPE-based methods. A poor level of test-retest reliability was shown for Banister's TRIMP (15.6% coefficient of variation [CV]), Lucia's TRIMP (10.7% CV), and sRPE (28.1% CV). Good reliability was shown for HR (3.9% CV) and a moderate level for RPE 6-20 (8.5% CV) as a measure of exercise intensity. These results suggest external work to be the most valid and reliable method for quantifying training load. Poor levels of reliability were reported for each of the HR-based TRIMP methods and RPE-based methods.

Effect of N-acetylcysteine on Cycling Performance after Intensified Training. Med. Sci. Sports Exerc., Vol. 46, No. 6, pp. 11141123, 2014. Purpose: This investigation examined the ergogenic effect of short-term oral N-acetylcysteine (NAC) supplementation and the associated changes in redox balance and inflammation during intense training. Methods: A double-blind randomized placebo-controlled crossover design was used to assess 9 d of oral NAC supplementation (1200 mgIdj1) in 10 well-trained triathletes. For each supplement trial (NAC and placebo), baseline venous blood and urine samples were taken, and a presupplementation cycle ergometer race simulation was performed. After the loading period, further samples were collected preexercise, postexercise, and 2 and 24 h after the postsupplementation cycle ergometer race simulation. Changes in total antioxidant capacity, ferric reducing ability of plasma, reduced glutathione, oxidized glutathione, thiobarbituric acid-reactive substances, interleukin 6, xanthine oxidase, hypoxanthine, monocyte chemotactic protein 1, nuclear factor JB, and urinary 15-isoprostane F2t concentration were assessed. The experimental procedure was repeated with the remaining supplement after a 3-wk washout. Eight participants completed both supplementation trials. Results: NAC improved sprint performance during the cycle ergometer race simulation (P G 0.001, Gp 2 = 0.03). Supplementation with NAC also augmented postexercise plasma total antioxidant capacity (P = 0.005, Gp 2 = 0.19), reduced exercise-induced oxidative damage (plasma thiobarbituric acid-reactive substances, P = 0.002, Gp 2 = 0.22; urinary 15-isoprostane F2t concentration, P = 0.010, Gp 2 = 0.431), attenuated inflammation (plasma interleukin 6, P = 0.002, Gp 2 = 0.22; monocyte chemotactic protein 1, P = 0.012, Gp 2 = 0.17), and increased postexercise nuclear factor JB activity (P G 0.001, Gp 2 = 0.21). Conclusion: Oral NAC supplementation improved cycling performance via an impr...

Purpose To assess the validity of methods for quantifying training load, fitness and fatigue in endurance athletes using a mathematical model. Methods Seven trained runners ( V? O2max: 51.7 ± 4.5 mL kg-1 min-1, age: 38.6 ± 9.4 years, mean ± SD) completed 15 weeks of endurance running training. Training sessions were assessed using a heart rate (HR), running pace and rating of perceived exertion (RPE). Training dose was calculated using the session-RPE method, Banisters TRIMP and the running training stress score (rTSS). Weekly running performance (1,500-m time trial), fitness (submaximal HR, resting HR) and fatigue [profile of mood states, heart rate variability (HRV)] were measured. A mathematical model was applied to the training data from each runner to provide individual estimates of performance, fitness and fatigue. Correlations assessed the relationships between the modelled and actual weekly performance, fitness and fatigue measures within each runner.

Aim. Athletes should match their energy intake with expenditure in order to maintain lean body mass. It is also important to consume adequate amounts of antioxidant vitamins and minerals to maintain health. Methods. To assess the dietary habits of six nationally ranked Australian swimmers physical training load and dietary intake (24 h food recall) and were recorded on a daily basis during a 4 day intensive physical training period. Results. The results showed no significant difference between energy intake and expenditure (P=0.58) or the amount of carbohydrate consumed (P=0. 14) compared to the Australian recommended daily intake (RDI). Athletes reported a significantly greater intake of vitamin A (P<0.01), vitamin C (P<0.01), vitamin E (P<0.01) and protein (P<0.01) than the RDI. Conclusion. It was concluded that these elite swimmers have an adequate dietary intake to allow for optimal physical training and performance.

There are few practical methods available for evaluating training loads (TL) during swimming. The purpose of this study was to examine the ecological validity of the session-rating of perceived exertion (RPE) method for quantifying internal TL in competitive swimmers using heart rate (HR)-based methods and distance as criterion measures. This study also examined the correspondence between athlete and coach perceptions of internal TL using the session-RPE method. Twelve (six male, six female) well-trained swimmers (mean ± SD: age 22.3 ± 3.1 years, weight 71.8 ± 11.6 kg, height 175.0 ± 9.0 cm) participated in this study. All subjects completed a swimming step test to evaluate individual HR zones and blood lactate profile before undertaking 20 swim training sessions where RPE, HR, and distance covered were recorded. Training load was then calculated for each session using the session-RPE, HR-based methods, and session distance. The session-RPE scores were correlated to HR-based methods for measuring internal TL as well as training distance for each swimmer. All individual correlations between session-RPE, HR-based methods (r = 0.55-0.94; p < 0.05), and distance measures (r = 0.37-0.81; p < 0.05) were significant. Two-way ANOVA showed that there was a significant interaction for training intensity × coach-athlete perception, indicating that coach RPE was lower than athlete RPE for low-intensity sessions and higher than athlete RPE at high-intensity sessions. The results of this study suggest that session-RPE may provide a practical, noninvasive method for quantifying internal TL in competitive swimmers.

The ability to measure and control the internal training load (TL) of athletes is important to optimize athletic performance. However, at present, there are no methods available for evaluating internal TL during swimming. The session-RPE method is a practical, noninvasive system used to quantify the internal TL placed on athletes. This article discusses how the session-RPE method may be used to monitor swim training and ultimately improve the training process of swimmers.

Few studies have described simple tests which can be used to provide an early warning of overreaching. The purpose of this study was to examine selected practical tests for monitoring changes in performance, fatigue and recovery of endurance athletes. Sixteen male triathletes were randomly assigned into matched groups. The normal training (NT) and intensified training (IT) groups completed 4 weeks of training followed by a 2-week taper. Physiological measures were taken pre- and post-overload and post-taper periods during an incremental treadmill test to exhaustion. Performance was assessed weekly using a 3-km run time trial (3 kmTT). Five-bound jump for distance (5BT) and submaximal running heart rate (HRsubmax) test were measured twice weekly and the Daily Analyses of Life Demands for Athletes (DALDA) were recorded. During the overload training period, the IT group completed 290% more training load than the NT group (p < 0.001). After the overload training period, 3 kmTT in the IT group was reduced compared to both pre-training (3.7%, p < 0.05) and the NT group (6.8%, p < 0.05). 5BT was decreased by 7.9% in the IT group following the overload period (p < 0.05). The IT group also demonstrated increases in stress reaction symptoms from the DALDA. Following the taper, the IT group improved 3 kmTT. In contrast, the performance, physiological and psychological markers of NT group remained relatively unchanged throughout the 6-week training period. There were weak significant correlations between weekly changes in 3 kmTT and 5BT (r = â0.37, p < 0.01). The DALDA and 5BT may be practical tests for assessing changes in performance, fatigue and recovery of endurance athletes.

© Springer International Publishing AG, part of Springer Nature 2018. Successful adaptation to climate change requires collective action by multiple actors operating at multiple scales. The Climate Adapted People Shelters (CAPS) project addressed the complex challenges of public exposure to urban heat, its impacts on the community, and the need for smarter public transport infrastructure to improve the liveability of cities in a warming world. It found that solutions to this problem require the integration of knowledge that includes, but is not limited to, the disciplines of environmental physics, innovation and design, business management, smart technology design, transport user behaviour and local governance. The project sought to foster innovation in climate adaptation through an open and human-centred design competition involving multiple stakeholders. The process was important because it revealed that community expectations about bus shelter design and performance were multi-faceted, and that the needs of infrastructure users could inform the practices of designing future public infrastructure. We discuss how to achieve more effective and broadly accepted urban design by utilizing open innovation, addressing urban resilience and climate adaptation, and leveraging the opportunities that lie within the use of data analytics and sensor technologies to address, in particular, transport user needs.
