“…In the motor skills dimension, the lack of engagement in physical activity could have led to reductions in speed, technical accuracy, sensorimotor coordination, and movement flow (Tran et al, 2017;Jukic et al, 2020). There is evidence that only 2-4 weeks of training cessation can cause a significant and marked loss of performance in both active populations and elite athletes (see Sousa et al, 2019).…”

The Coronavirus experience (CE) presents a highly challenging period for sport performers (e.g., athletes, coaches, referees), with potential effects on their lives and career trajectories. In this article, we initially conceptualize the CE using the scheme of change for sport psychology practice (Samuel and Tenenbaum, 2011a). Within this framework, the CE is understood as a longitudinal, multifaceted, unpredicted, non-controlled change-event, with four distinct stages: (a) a pre-Coronavirus stage with unique career contextual conditions (i.e., stable engagement or a transitional period), (b) Coronavirus stage-A accompanied by instability and confusion, emotional response, and cognitive appraisal, (c) Coronavirus stage-B characterized by active coping or regression, and (d) Coronavirus stage-C; instability endures or decreases, depending on career trajectory. The CE presents sport performers with modifications in various dimensions, including physical and physiological, motor skills, psychosocial and self-identity, relationships, performance and achievement, motivation and aspirations, organizational-occupational, and micro-and macro-cultural issues. Sport performers can exhibit several emotional responses (i.e., positive, negative, neutral), and consequential coping endeavors. The development of the change process is underlined by key decisions, manifested in sport performers' attempts to implement responsive change in these dimensions (e.g., adapt their diets, sleep routines, and exercise regimen). The second part of the article discusses applied practice considerations, presenting various techniques and methodologies which practitioners can apply while consulting from a change-based perspective. Ethical issues pertaining to the formation of effective therapeutic relationships during this period are also assessed. The conclusions offer future avenues for researchers and practitioners when attempting to evaluate and cope with this global phenomenon.

“…For Tran et al 30 , the effect of detraining for 4 weeks caused a considerable drop in the height of the vertical jump (-5.3%), in the peak vertical velocity (-3.7%) and in the isometric strength (-5.5%). In addition, the sensorimotor capacity decreased, indicating that the athletes took longer (61.4%) to reach stability in a landing task.…”

In March 2020, the World Health Organization (WHO) declared the disease caused by the SARS-CoV2 virus, known as COVID-19, to be a pandemic. The sporting world, too, is suffering from the global effects of this disease, with the postponement or cancellation of competitions, including the 2020 Tokyo Olympic Games. As a proposal for containing the disease, social isolation was declared. Despite the importance of this measure, it was harmful for Olympic athletes, as they had to stay away from their training site and trainers, as well as their interdisciplinary teams. It is therefore important to study this harm caused, in order to minimize it. In general, it is believed that regular physical activity is associated with improved immune system functioning. The lack of training can therefore have significant consequences for the performance and health of the Olympic athlete. From the athlete's point of view, the impaired immune system, due to the reduced frequency of physical exercise, leaves them more vulnerable to contracting or developing infections or other diseases. The risk of harm due to the decreased performance of preventive works is also evident in this population. The reductions in training load and intensity can cause changes in the athlete's body composition and affect various aspects of cardiorespiratory fitness, as well as reducing strength levels and muscle potency. In relation to the athlete's mental health, two aspects are particularly challenging: isolation and uncertainty. Based on the possible harm caused by social isolation, the need is seen for a specific and joint work, in an attempt to minimize it. This work addresses the following topics: (I) context: transmission, symptoms, diagnosis, treatment, discharge criteria, isolation and post-pandemic consequences; (II) harm and proposals: nutritional, physiological, biomechanical and psychological. Level of evidence II; Review Article.

“…Thus, attenuating loss of neuromuscular capability during this period is essential to ensure performance is not compromised when competition resumes. When interpreting the available resistance training research, it appears that strength may be partially or completely maintained in the short term (e.g., up to 3 weeks) [ 22 ] but will be compromised after 4 weeks (e.g., surfing athletes) [ 23 ] and begin to decay in team-sport athletes [ 24 ] and/or be substantially lost after 5 weeks without training in physically active males [ 25 ]. Tran et al [ 23 ] also noted a reduction in athletes’ sensorimotor ability which may be an important consideration where technical and/or skillful actions are required (e.g., complex WL movements).…”

Further, Izquierdo et al [ 26 ] demonstrated reductions in maximal strength and power of 6% to 9% and 14% to 17% in the upper- and lower-limbs, respectively, following 4 weeks of a complete cessation of training in physically active men.…”

The ongoing global pandemic brought about by Coronavirus II (SARS-Cov-2 or COVID-19) has caused an ongoing cessation of sporting competitions and training facility closures. This is a fundamental challenge for amateur and elite sporting professionals. Although recommendations have been provided for team-sport athletes to maintain general and sport-specific conditioning, these methods are often not optimal for strength athletes (i.e., powerlifting (PL) and weightlifting (WL)) due to the unique and narrow set of performance requirements posed by these sports. The purpose of this review is to provide evidence-based information and recommendations and highlight potential strategies and approaches that may be used by strength (PL and WL) athletes during the current global crisis. Collectively, we provide evidence from resistance training literature regarding the loss of muscle strength, power and mass, minimum training frequencies required to attenuate such losses and training re-adaptation. Additionally, we suggest that time off training and competition caused by ongoing restrictions may be used for other purposes, such as overcoming injury and improving movement quality and/or mobility, goal setting, psychological development and emphasizing strength sports for health. These suggestions are intended to be useful for coaches, strength athletes and organizations where existing training strategies and recommendations are not suitable or no longer feasible.
