The coronavirus disease (COVID-19), caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection, is leading to unknown and unusual health conditions that are challenging to manage. Post-COVID-19 syndrome is one of those challenges, having become increasingly common as the pandemic evolves. The latest estimates suggest that 10 to 20% of the SARS-CoV-2 patients who undergo an acute symptomatic phase are experiencing effects of the disease beyond 12 weeks after diagnosis. Although research is beginning to examine this new condition, there are still serious concerns about the diagnostic identification, which limits the best therapeutic approach. Exercise programs and physical activity levels are well-known modulators of the clinical manifestations and prognosis in many chronic diseases. This narrative review summarizes the up-to-date evidence on post-COVID-19 syndrome to contribute to a better knowledge of the disease and explains how regular exercise may improve many of these symptoms and could reduce the long-term effects of COVID-19.
A better understanding of in-game competition demands potentially improves coaching strategy and quality. However, there is very limited information about game patterns in padel, a very modern racket sport born in the 70'. The purpose of this study was therefore to quantify and classify game dynamics during the match in professional padel players through a multivariate decision tree approach including technical, spatial and effectiveness indicators. The results determined three main game styles strongly defined by the court zone (net, middle and baseline). Additionally, particular technical, spatial and effectiveness indicators were identified in each zone. In net and middle areas (offence) stood the use of volleys and over-head strokes on the center lane to both keep a positional advantage and solve the point. Conversely in the baseline (defense), the use of corner side walls and the domain of lobs showed to be relevant. It is also remarkable the high rate of backhand groundstrokes, involving over four out of ten actions. This information may have relevant implications for coaches working in padel by providing a novel hierarchically organization of game dynamics, which helps in designing training and conditioning programs close to real competitive situations.
The purpose of this study was to analyse differences in rally length considering attack effectiveness, a players’ location and a game outcome in professional padel players. A total of 1527 rallies from 10 male matches of the 2013 Masters Finals of the World Padel Tour were registered through systematic observation. Data treatment included non-parametric mean comparisons (Mann-Withney and Kruskal-Wallis tests), and association analyses (crosstabs and Chi square analysis). In overall, 40% of unforced errors were made within the first 4 s of the rally, over 50% of points were scored between the 5th and 11th s, and 30% of forced errors occurred after the 11th –s of the rally. Hence, the ability to score in rallies of over 11 s duration and not making unforced errors within the first 4 s contributed to the rally outcome. More specifically, winners played longer rallies compared to losers (10.42 ± 7.77 s vs. 8.42 ± 6.43 s); particularly at the net, when scoring from the baseline (11.04 ± 7.64 s vs. 8.90 ± 5.41 s) and making forced (8.86 ± 7.44 s vs. 6.86 ± 6.24 s) and unforced errors (11.91 ± 9.47 s vs. 8.33 ± 6.92 s). Such knowledge may have implications in the design and structure of specific training programmes for padel players according to competition requirements.
The aim of this study was to determine the effectiveness of physical exercise, respiratory muscle training and the self-management WHO recommendations leaflet on the recovery of physical fitness, quality of life and symptom status in people with post COVID-19 conditions. Eighty non-hospitalized adults with a post-COVID-19 condition were randomly assigned to one of four 8-week parallel intervention groups: multicomponent exercise program based on concurrent training- CT (n= 20; 3 resistance and endurance supervised sessions per week at low-moderate intensity); b) inspiratory muscle training- RM (n= 17; 2 standardized daily sessions); c) a combination of both of the above- CTRM (n= 23); d) control group- CON (n= 20; following the WHO guidelines for post-COVID-19 related illness rehabilitation). No significant differences between groups were detected at baseline. While no significant differences between interventions were detected in the VO2max, significant individual improvements were identified in the CT (7.5%; ES=0.38) and CTRM (7.8%; ES=0.28) groups. Lower body muscle strength significantly improved in the CT and CTRM (14.5-32.6%; ES=0.27-1.13) groups compared to RM and CON (-0.3-11.3%; ES=0.19-0.00). The CT and CTRM groups improved significantly for dyspnea and fatigue, as did the health status. In addition, significant differences between interventions were described in fatigue and depression scales favouring CT and CTRM interventions. An individualized and supervised concurrent training with or without respiratory muscle training was safer and more effective than self-care recommendations and inspiratory muscle training alone, to regain cardiovascular and muscular fitness, improve symptom severity and health status in outpatients with post-COVID-19 conditions.
Purpose The aim of the study was to compare the outcomes of patients with post‐COVID‐19 condition undergoing supervised therapeutic exercise intervention or following the self‐management WHO (World Health Organization) rehabilitation leaflet. Methods A randomized controlled trial was carried out that included 39 participants with post‐COVID‐19 condition who had a chronic symptomatic phase lasting >12 weeks. Comprehensive medical screening, patient‐reported symptoms, and cardiorespiratory fitness and muscular strength were assessed. Patients were randomly assigned to a tailored multicomponent exercise program based on concurrent training for 8 weeks (two supervised sessions per week comprised resistance training combined with aerobic training [moderate intensity variable training], plus a third day of monitored light intensity continuous training), or to a control group which followed the WHO guidelines for rehabilitation after COVID‐19. Results After follow‐up, there were changes in physical outcomes in both groups, however, the magnitude of the change pre–post intervention favored the exercise group in cardiovascular and strength markers: VO 2 max +5.7%, sit‐to‐stand −22.7% and load‐velocity profiles in bench press +6.3%, and half squat +16.9%, (p < 0.05). In addition, exercise intervention resulted in a significantly better quality of life, less fatigue, less depression, and improved functional status, as well as in superior cardiovascular fitness and muscle strength compared to controls ( p < 0.05). No adverse events were observed during the training sessions. Conclusion Compared to current WHO recommendations, a supervised, tailored concurrent training at low and moderate intensity for both resistance and endurance training is a more effective, safe, and well‐tolerated intervention in post‐COVID‐19 conditions.
The aims of this study were to describe and compare the anthropometric and physical fitness attributes of male padel players according to their competitive level, and to establish a functional anthropometric and physical profile. A total of 60 males participated in the present study. Athletes were grouped according to competition level, forming an elite group (n = 25) and a subelite group (n = 35). Anthropometric variables, hand grip and lumbar isometric strength, flexibility, and lower-body muscular strength were measured. Elite padel players were significantly older and showed significantly lower values for the thigh and calf skinfolds, the sum of six and eight skinfolds, and the sum of lower-limb skinfolds than the subelite group. Elite padel players also had significantly lower values than subelite players for body fat percentage and thigh fat area, whilst showing significantly higher values for lumbar isometric strength. Somatotype of the elite padel players could be defined as endo-mesomorphic. Results suggest that training and talent identification of padel players should focus on their anthropometric characteristics and physical fitness, with these being different between elite and subelite athletes. Normative data could help coaches throughout the talent identification process and in the design of training programs when seeking to optimise sports performance.
The aims of the present study were to examine the fitness characteristics of professional padel players and to determine differences in physical performance regarding players’ gender. Thirty professional padel players (men: n = 15, age = 27.4 ± 6.8 years, height = 177.9 ± 4.0 cm; women: n = 15, age = 30.0 ± 4.2 years, height = 166.6 ± 4.8 cm) completed a 4-day evaluation process, including: isometric handgrip strength, sit and reach, 10 × 5 shuttle test, countermovement jump (CMJ), squat jump (SJ), Abalakov test, one-repetition maximum test (bench press, leg extension, leg curl, lat pulldowns, overhead press, and shoulder press), anthropometry and VO2 max tests. The men players had higher values in terms of weight, height, one maximum repetition, jump tests (CMJ and ABK) and VO2 max test than the women (p < 0.005). By contrast, the women had higher values for fat mass (p = 0.005; ES: 2.49). The values from this multifaceted test battery can be a useful guide for coaches regarding players’ development in future evaluations and monitoring.
The aim of this study was to analyze the distribution of padel strokes, their effectiveness, direction, and court zone, comparing between the winning and losing pairs in the match and the playing side of the players. The sample included 8441 strokes corresponding to 1055 points out of a total of nine padel matches in the First National Category. The variables analyzed were type of stroke, court area, effectiveness and directions of the strokes, match outcome, and game side. Matches were analyzed through systematic observation. The results showed that the winning pair made a significantly higher percentage of winners, and cross-court smashes and volleys from the offensive zone. In addition, players on the left side executed a higher percentage of cross-court and winning shots than the players on the right side. Such knowledge may constitute a useful guide in the design of appropriate game strategies and specific training sessions based on the shots that will help players to win the match according to the role of the player and depending on their game side.
