MATERIALS AND METHODS: This scoping review selected studies published from January 2002 to November 2022. The articles were searched through PubMed Central, BMJ Journal, Science Direct, and Scopus using "motor control", "ankle sprain" and "strengthening exercise" as the keywords. After finding the articles, the information extracted included author, year of publication, country, objective, type of study, and motor control analysis summary. The literature search strategy used Preferred Reporting Items for Systematic Review and a meta-analysis (PRISMA) where studies that are related to strengthening exercise and motor control were selected.
RESULTS: From the initial search, 50 articles were found. After processing, only ten articles were further reviewed. The findings demonstrated strengthening exercises provide changes in neurophysiological parameters with motor performance, improved motor control, strength, balance, pain, and functional movement in footballers with sprained ankles.
CONCLUSION: This review suggests the application of strengthening exercise interventions not only improves motor control, but strength, balance, pain, and functional performance among footballers with sprained ankles.
PURPOSE: The authors explored the training practices of football players worldwide during the COVID-19 lockdown.
METHODS: Football players (N = 2482, 30% professional, 22% semipro, and 48% amateur) completed an online survey (May-July 2020) on their training practices before versus during lockdown (March-June 2020). Questions were related to training frequency and session duration, as well as training knowledge and attitudes.
RESULTS: Before lockdown, more professional (87%) than semipro (67%) and amateur (65%) players trained ≥5 sessions/wk, but this proportion decreased during the lockdown to 55%, 35%, and 42%, respectively. Players (80%-87%) trained ≥60 minutes before lockdown, but this proportion decreased to 45% in professionals, 43% in amateurs, and 36% in semipros during lockdown. At home, more than two-thirds of players had training space (73%) and equipment (66%) for cardiorespiratory training, while availability of equipment for technical and strength training was <50% during lockdown. Interactions between coach/trainer and player were more frequent (ie, daily) among professional (27%) than amateur (11%) and semipro (17%) players. Training load monitoring, albeit limited, was mostly performed by fitness coaches, more so with professionals (35%) than amateurs (13%) and semipros (17%). The players' training knowledge and attitudes/beliefs toward training were relatively modest (50%-59%).
CONCLUSION: COVID-19 lockdown negatively affected training practices of football players worldwide, especially amateurs and semipros, for example, in training frequency, duration, intensity, technical, recovery, and other fitness training and coaching-related aspects. During lockdown-like situations, players should be monitored closely and provided appropriate support to facilitate their training.
HYPOTHESIS: The addition of WR worn on the lower legs during an on-field warm-up would lead to decreases in relatively high-intensity external TL metrics, such as distance covered >6.11 m∙s-1 and acceleration and deceleration >/<3 m∙s-2 and increases in internal TL during the warm-up, yet would have little effect on the subsequent training session when WR was removed.
STUDY DESIGN: Matched-pair randomized design.
LEVEL OF EVIDENCE: Level 3.
METHODS: A total of 28 soccer players were allocated to either a WR training (WRT = 14) or unloaded (control [CON] = 14) group. Both groups performed the same warm-up and on-field training for 8 weeks, with the WRT group wearing 200 g to 600 g loads on their lower leg during the warm-up. External TL was measured via global positioning system data and internal TL was assessed using session rating of perceived exertion (sRPE × time per session).
RESULTS: No statistically significant between-group differences (P ≥ 0.05) were identified for any TL measurement during either warm-ups or training sessions. Lower leg WR resulted in trivial to moderate effects for all external TL metrics (-16.9% to 2.40%; d = -0.61 to 0.14) and sRPE (-0.33%; d = -0.03) during the warm-up and trivial to small effects on all external TL metrics (-8.95% to -0.36%; d = -0.45 to -0.30) and sRPE (3.39%; d = 0.33) during training sessions.
CONCLUSION: Warming up with lower leg WR negatively affects neither the quality and quantity of the warm-up nor the subsequent training session once WR is removed.
CLINICAL RELEVANCE: Using WR on the lower leg during on-field warm-ups may be a means to "microdose" strength training while not unduly increasing TL. However, further research is needed to determine the influence of WR on strength qualities.
PURPOSE: Investigating injury and illness epidemiology in professional Asian football.
STUDY DESIGN: Descriptive prospective study.
METHODS: Professional teams from the Asian Football Confederation (AFC) league were followed prospectively for three consecutive AFC seasons (2017 through 2019, 13 teams per season, 322 team months). Time-loss injuries and illnesses in addition to individual match and training exposure were recorded using standardised digital tools in accordance with international consensus procedures.
RESULTS: In total, 232 665 hours of exposure (88.6% training and 11.4% matches) and 1159 injuries were recorded; 496 (42.8%) occurred during matches, 610 (52.6%) during training; 32 (2.8%) were reported as 'not applicable' and for 21 injuries (1.8%) information was missing. Injury incidence was significantly greater during match play (19.2±8.6 injuries per 1000 hours) than training (2.8±1.4, p<0.0001), resulting in a low overall incidence of 5.1±2.2.The injury burden for match injuries was greater than from training injuries (456±336 days per 1000 hours vs 54±34 days, p<0.0001). The two specific injuries causing the greatest burden were complete ACL ruptures (0.14 injuries (95% CI 0.9 to 0.19) and 29.8 days lost (29.1 to 30.5) per 1000 hours) and hamstring strains (0.86 injuries (0.74 to 0.99) and 17.5 days (17.0 to 18.1) lost per 1000 hours).Reinjuries constituted 9.9% of all injuries. Index injuries caused 22.6±40.8 days of absence compared with 25.1±39 for reinjuries (p=0.62). The 175 illnesses recorded resulted in 1.4±2.9 days of time loss per team per month.
CONCLUSION: Professional Asian football is characterised by an overall injury incidence similar to that reported from Europe, but with a high rate of ACL ruptures and hamstring injury, warranting further investigations.
Methods: Data were collected from 278 male soccer players aged 13-38 years (mean [M] = 17.42 ± 4.36) with the number of competitive soccer experiences ranging from 1-28 years (M = 7.51 ± 4.23 years). Participants had at least a year of experience in the sport of soccer completed the validated passion scale, sports courage scale and demographic form.
Results: Analyses revealed that soccer players with higher levels of total courage (P < 0.001), have more experience in soccer (P = 0.011), and their soccer level being professional (P < 0.001) had a significantly higher score in harmonious passion. There was no significant difference in obsessive passion among different level of total courage (P = 0.154). However, soccer players with more experience (P = 0.011) and higher soccer level being professional (P < 0.001) demonstrated a significant higher score in obsessive passion.
Conclusion: In conclusion, soccer players with higher harmonious and obsessive passionate attributes had higher courage (except for mastery). In addition, the courageous and passionate traits of the soccer players played meaningful roles in indicating individual and performance variables.
Materials and method: During the tournament, 14 teams participated in men's football, 12 teams in men's futsal and 11 teams in women's futsal. The biannual event involved athletes aged under 21 years. A medical report form used by FIFA Medical Assessment and Research Centre (F-Marc), was provided to the physiotherapists and team doctors of all the teams to report all injuries after each match.
Results: The response rate was 84.62% in football and 59.76% in futsal. A total of 48 injuries were reported from 26 football matches, equivalent to 64.64 injuries per 1000 match hours (95%CI 46.35 to 82.93). In futsal, a total of 48 injuries from 41 matches were reported, equivalent to 292.42 injuries per 1000 match hours (95% CI 209.7 to 375.14). The rate of injury in women futsal players was higher compared to men: 358.21 versus 247.04 injuries per 1000 match hours (p=0.224). Futsal recorded higher injuries per 1000 match hours than football (p<0.001).
Conclusion: The rate of severe injury in futsal and football recorded in the study as compared to previous studies gave rise to serious concerns. Hence, there was an urgent need to pay more attention to injury prevention strategies.
