Sport psychology services to high performance athletes during These are trying times for us all. COVID-19 has altered our lives as citizens. The changes associated with the current pandemic have presented sport and exercise psychologists with many challenges and opportunities related to sport performance, physical activity and health. Here, we focus on what was, and is presently, being encountered by mental performance consultants in relation to the aspiring Olympic athletes they are supporting.Within recent weeks, mental performance consultants working with Olympic aspirants have evidenced a growing number of suggestions how aspiring athletes might proceed in their sports and in their broader lives, based on their national conditions and regional responses to the pandemic. Each national funding agency, Olympic committee, federal government, and sport organisation, is rolling out strategies of how mental performance consultants can work effectively with clients in what for many, but not all, is a socially distanced world.Discussions have varied from the challenges that athletes are encountering to issues associated with social isolation, career disruption, qualification process uncertainty, and unconventional and limited access to effective training environments and training partners. Underpinning these considerations is the health and wellbeing of athletes in their pursuits toward excellence.Historically, editorials within the International Journal of Sport and Exercise Psychology were paired with special issues, such as the one focused on international approaches to Olympic athlete performance, published in 2016. Within the current editorial, however, there is a deviation in approach, caused by a global circumstancesport is not being experienced as usual; the challenges posed for those engaging in sport, region by region, are uncharted.The focus we have set, in what should have been the 2020 Olympic year, is placed on the shared challenges and the emergence of solutions that mental performance consultants are presently undertaking in their work with athletes. The co-authors of this editorial are from Asia, Europe, and North America. We have published on the topic of Olympic performance and we are currently immersed in work with Olympic athletes in our respective countries. What follows is a synthesised commentary.The reader might posit that embedded in each author's work, approaches are idiosyncratic and driven partly by culture and context, which is a correct assumption. For example, some of us are working from a distance, where others are consulting face-to-face. However, what we share in common is astounding, despite our respective locations and circumstances. We present this editorial, structured into three temporal stages: (a) before the 2020 Olympics were postponed, (b) once the Olympics were postponed, and (c) the path being re-set toward Tokyo, 2021. Before Olympic postponementLife tends to be normal before crisis transitions are experienced, within and outside of highperformance sport. Within high-per...

Building on the work of Terry and colleagues (Terry, P. C., Lane, A. M., Lane, H. J., & Keohane, L. (1999). Development and validation of a mood measure for adolescents. Journal of Sports Sciences, 17, 861-872; Terry, P. C., Lane, A. M., & Fogarty, G. J. (2003). Construct validity of the Profile of Mood States-Adolescents for use with adults. Psychology of Sport & Exercise, 4, 125-139.), the present study examined the validity and internal consistency reliability of the Chinese version of the Brunel Mood Scale (BRUMS-C) among 2,548 participants, comprising adolescent athletes (n = 520), adult athletes (n = 434), adolescent students (n = 673), and adult students (n = 921). Both adolescent and adult athletes completed the BRUMS-C before, during, or after regular training and both adolescent and adult students completed the BRUMS-C in a classroom setting. Confirmatory factor analyses (CFAs) provided support for the factorial validity of a 23-item six-factor model, with one item removed from the hypothesised measurement model. Internal consistency reliabilities were satisfactory for all subscales across each of the four samples. Criterion validity was supported with strong relationships between the BRUMS-C, abbreviated POMS, and Chinese Affect Scale consistent with theoretical predictions. Multi-sample CFAs showed the BRUMS-C to be invariant at the configural, metric, strong, and structural levels for all samples. Furthermore, latent mean difference analyses showed that athletes reported significantly higher levels of fatigue than students while maintaining almost the same levels of vigour, and adolescent students reported significantly higher levels of depressed mood than the other three samples.

This study examines the impacts of tropical North Atlantic (TNA) sea surface temperature anomaly (SSTA) on western North Pacific (WNP) landfalling tropical cyclones (TCs). The authors find that TNA SSTA has significant negative correlations with the frequency of TCs making landfall in China, Vietnam, the Korean Peninsula and Japan, and the entirety of East Asia. TNA SSTA influences the frequency of TC landfalls in these regions by regulating TC genesis location and frequency associated with modulated environmental conditions. During cold TNA SST years, larger low-level relative vorticity and weaker vertical wind shear lead to more TC formations over the South China Sea (SCS) and western Philippine Sea (WPS), and larger low-level relative vorticity, higher midlevel relative humidity, and weaker vertical wind shear result in more TC formations over the eastern part of WNP (EWNP). More TCs forming over different regions are important for more TC landfalls in Vietnam (mainly forming over the SCS and WPS), south China (predominantly forming over the SCS), Taiwan (mostly forming over the WPS), and the Korean Peninsula and Japan (forming over the WPS and EWNP). Tracks of these landfalling TCs basically follow the mean steering flow in spite of different directions of steering flow anomalies in the vicinity. The modulation of large-scale environments by TNA SSTA may be through two possible pathways proposed in previous studies: the Indian Ocean relaying effect and the subtropical eastern Pacific relaying effect. The results of this study suggest that TNA SSTA is a potential predictor for the frequency of TCs making landfall in China, Vietnam, the Korean Peninsula and Japan, and the entirety of East Asia.

This study finds a significant positive correlation between the Pacific meridional mode (PMM) index and the frequency of intense tropical cyclones (TCs) over the western North Pacific (WNP) during the peak TC season (June–November). The PMM influences the occurrence of intense TCs mainly by modulating large-scale dynamical conditions over the main development region. During the positive PMM phase, anomalous off-equatorial heating in the eastern Pacific induces anomalous low-level westerlies (and cyclonic flow) and upper-level easterlies (and anticyclonic flow) over a large portion of the main development region through a Matsuno–Gill-type Rossby wave response. The resulting weaker vertical wind shear and larger low-level relative vorticity favor the genesis of intense TCs over the southeastern part of the WNP and their subsequent intensification over the main development region. The PMM index would therefore be a valuable predictor for the frequency of intense TCs over the WNP.
