Resumen:	The objective of this study is to describe the relationship between injury incidence (IL) and maturity in male elite handball's player (HbP). Prospective study during two seasons, evaluating the sports injuries, maturity status and exposure time in hours in 133 young handball's players, under the UEFA methodology model for epidemiological studies. We discuss the maturity stage with different parameters, the Tanner's stage, puberty stages, peak high velocity, testicular volume, and the bone age. Finally, 190 injuries for a total of 34.222 h of exposure were registered. The average total Injury Incidence (IIn) by categories was 5,6 injury/1000 h of exposure. Injury Incidence during competition: 21,8 injuries/1000 hs and in training: 3,1 injuries/1000 hs without statistically significant between IIn, chronological age and different maturity stage by ANOVA. The multivariate statistical analysis registers tendency associations between IIn in competition for category (P = 0,07), and the IIn in training for Tanner stage (P = 0,091) and puberty (P = 0,021). In conclusion: there is not a significant difference in total IIn by ages categories in handball players but there is statistically significance tendency respect to some maturity parameters under a multivariate analysis. This last result must be considered when planning training seasons and strategies for injury prevention in the context of the formative handball. (AU)

Resumen:	The aim of this study was to examine the effect of various contextual factors, such as relative age, biological maturation, or competitive level, on the jumping performance of young football goalkeepers. Vertical jump performance was evaluated in a selection of goalkeepers (n = 110) from U-14 and U-16 category teams. The sample was categorized by relative age, biological maturation, and competitive level. The results revealed a trend in the overall sample towards an overrepresentation of goalkeepers born in the early months of the year. Maturity status influenced the most in jumping performance of young goalkeepers (SJ: F = 11.27, p < .001, ηp2 = 0.187; CMJ: F = 8.72, p < .001, ηp2 = 0.162; AJ: F = 8.37, p < .001, ηp2 = 0.146), while the birth quartile had no effect on the jumping performance in the sample. Statistical differences were significant for SJ and CMJ between competitive level groups in the U-14 group only. (F = 5.37, p = .008, ηp2 = 0.186) and CMJ (F = 4.54, p = .016, ηp2 = 0.159). This study showed a greater association between maturation and jumping performance in young football goalkeepers rather than with relative age, which could influence the selection process in this field position at early ages.

Resumen:	Inertial devices allow for obtaining a large amount of information related to external load during official competitions. The study aimed to analyse fatigue in different functional classification players of a Football 7-a-side for people with cerebral palsy or acquired brain injury team, considering the movements, speed changes and impacts during the 2020 Spanish National League matches (n = 12). The analyzed independent variables were the different functional classifications (FC) of the players, FC1, FC2 and FC3, and also time. Regarding the dependent variables, kinematic objective external load (displacements and speed changes), and neuromuscular objective external load (impacts) were considered. This study is an empirical investigation that follows an associative and descriptive analysis, ANOVA test, and a Bonferroni post hoc test (multiple comparisons) were carried out between the external load variables based on FC and time. The results show differences between FC1 for people with greater functional limitation to FC3, and athletes with less functional limitation depending on the time of the match. FC2 players presented greater competitive demands in specific moments of the match than FC3 athletes because of the requirements of the competition. Furthermore, evaluating different FC players with inertial devices in official competitions provides useful information regarding the demands of Fa7PC players, which is fundamental for daily training tasks management and injury risk prevention in Fa7PC. The large number of variables associated with inertial devices data collection during training sessions and official competitions in Fa7PC allows us to understand the demands of CP players, as well as how to make decisions during the games and training process, namely for reducing the injury risk.

Resumen:	There is little information regarding the acute repercussions of anterior cruciate ligament (ACL) reconstruction on muscle activation, especially on the proximal hip muscles. Thus, this study analyzed the acute effects of ACL reconstruction with doubled semitendinosus/gracilis (ST/G) autografts on lower limb muscle activation. Fourteen male recreational athletes that presented a primary unilateral ACL rupture and underwent the ACL reconstruction with an ST/G graft. Surface electromyographic (sEMG) signal were recorded from each participant during the maximal voluntary isometric contraction (MVIC) of the gluteus maximus and gluteus medius, vastus lateralis and vastus medialis, semitendinosus, biceps femoris, and medial gastrocnemius muscles and also during bipodal mini-squatting with open and closed eyes, before surgery and 15 days postoperatively. (sEMG) signal were normalized to isometric peak electromyography. The postoperative assessment showed reduced muscle activation in the gluteus maximus (p = 0.013, d:0.48) in non-operated limb and also in the muscle gluteus medius (p = 0.013, d:0.79), vastus medialis (p = 0.035, d:0.63) semitendinosus (p = 0.001, d:2.46), biceps femoris (p<0.001, d:1.5), and medial gastrocnemius (p = 0.001, d:1.45) during MVIC in the operated limb. The postoperative assessment also revealed alterations in the sEMG activity of the hip and local thigh muscles in the operated and non-operated limbs during mini-squatting with opened eyes and closed eyes (p<0.05). ACL reconstruction surgery with a doubled ST/G autograft may promote immediate changes in lower limb muscle activation of the operated and non-operated limb. (AU)

Resumen:	Introduction Groin injuries are common among rink hockey players. Monitoring the main risk factors can reduce the likelihood of suffering such injury. The objective of this study was to evaluate the effect of a competitive congestion period on the squeeze strength of the hip adductor muscles in a group of adolescent rink hockey players, and whether the strength reduction exceeded the injury risk threshold (>15%) for sustaining a groin injury. Materials and Methods Twenty U-16 athletes (9 females) participated in the study. Eighty-three adductor strength measurements were recorded after 10 games (2109 min of play). Function was assessed using the Sport subscale of the Hip and Groin Outcome Score (HAGOS) questionnaire. A simple linear regression model was used to analyze the accumulated time-strength relationship, and the pre-tournament and post-tournament HAGOS results were compared. Results The accumulation of games resulted in a significant strength reduction in male players' (R2= 0.27), but not in females. Eighty-five percent of the sample had their strength reduced to values at risk compared to baseline strength, but none of them stopped their activity due to discomfort in the groin region. HAGOS results were not affected by the competitive congestion (p = 0.07û0.48). Conclusion Match congestion can negatively impact adductor strength. However, there may not be a relationship between strength loss above 15% and the appearance of a groin injury. (AU)

Título:	Mindfulness traits as potential inhibitor of irrational performance beliefs and intolerance of uncertainty amongst elite female basketball players
Fuente:	Apunts, Med. esport (Internet);58(220), October - December 2023. tab.

Resumen:	Dispositional mindfulness promotes adaptive responses to pressure situations and reduce anxiety and emotional distress, which are common manifestations in sport. The aim of this study was to investigate the role of mindfulness characteristics in the display of irrational performance beliefs and intolerance of uncertainty amongst a sample of elite female basketball players (N = 67, Mage = 25.73 years, SD = 4.4). An online Qualtrics survey containing demographic items, the Mindfulness Attention Awareness Scale, Irrational Performance Beliefs Inventory, and Intolerance of Uncertainty Scale was used to collect the study data, which were analysed using SPSS. The results from both Pearson correlation coefficient and simple linear regression analyses indicated that higher levels of dispositional mindfulness are significantly related to elite female basketball players having fewer irrational beliefs about their performance and being more tolerant of uncertain situations in their sport. One-way analysis of variance further indicated a significant difference between low, average, and high mindfulness groups, with Tukey's post-hoc analyses confirming that participants with high mindfulness displayed significantly fewer rigid, extreme, self-defeating performance beliefs in sport, and were less prone to impulsive reactions to uncertain circumstances compared to participants with low mindfulness. Sport psychology practitioners are encouraged to consider the integration of mindfulness assessment and training protocols with traditional cognitive behaviour modification approaches to counter female basketball players' display of distorted beliefs in sport and adverse reactions to ambiguous experiences.

Resumen:	Introduction: Continuous evaluations of athletes, including strength testing, can help control performance improvement or facilitate the restoration of normality after an injury. The aim of the present study was to prospectively determine the peak torque (PT), angle at which PT is achieved, and functional ratios of flexors and extensors thigh muscles during one season. Material and methods Thirty semi-professional male athletes competing in long jumping (n = 10), javelin throwing (n = 10), and sprinting (n = 10) participated. PT was evaluated in relation to limb length; the angle at which PT was achieved was obtained from the force-curve displayed in the isokinetic dynamometer; functional ratios were calculated by dividing concentric hamstring strength by eccentric quadriceps strength (flexor ratio) or vice-versa for the extensor ratio. Assessment was performed at 60º/s and 300º/s. Results Significant variations were seen for both extensor and flexor PTs at different stages of the season, with moderate to large effect sizes observed (effect size (d) = 0.49û0.93). Functional ratios and the angle at which peak torque was achieved remained stable throughout the season. Conclusions Thigh muscle strength is unstable throughout a track and field season, coaches or medical staff should consider these findings when programming training sessions or rehabilitating an athlete.

Resumen:	The aim of this study was to determine associations between workload, myosin isoforms, and performance in professional basketball, by following the progress of a professional basketball team over four consecutive seasons. Thirty male professional basketball players (age, 27.6 ± 4.1 years;height, 200.1 ± 9.4 cm;weight, 98.5 ± 12.6 kg) from an elite professional basketball team participated in this retrospective observational study. To analyze muscle response and which types of fiber were most involved, fast and myosin in serum were evaluated from three blood samples taken during the season, using enzyme-linked immunosorbent assay (ELISA). Parameters recorded were: exposure time,. Slow and fast myosins for muscle responses. Competitions won, ranking, and mean points scored for performance. Average values per season analysed were 280.1 ± 58 h of exposure to practice,1440.58±533.46µlmol/L of fast and 1178.75±427.75 µmol/L of slow myosin. Performance, assessed as team ranking was 6879.5 ± 985.37 u.a. per season and 90.72±2.79 u.a. per game, winning 7 competitions. Large negative relationships could be observed between slow myosins and exposure time (rho=−0.63;p=.02); There were possible associations between slow myosins and player mean performance per game (R2=0.98;p<.01) and team performance outcomes achieved (R2=0.83;p = 01) during these four seasons. Higher slow serum myosin values could be related to higher exposure time, and lower slow serum myosin values could be associated with better player and team performance. (AU)

Resumen:	The aim of the study was to monitoring psychophysiological responses among volleyball players in the microcycle with a high-performance competition game scheduled. Methods: Ten male athletes (26.6 ± 5.3 years) from an adult volleyball team participated in the study. The variables session Rating of Perceived Exertion (Session RPE), Total Quality of Recovery scale (TQR), Well-being questionnaire (WB), testosterone, cortisol, and testosterone/cortisol Ratio (T:C ratio) were evaluated during the microcycle before the game. Results: Differences were observed in the daily training load (F = 23.776; p < 0.001), TQR (F = 10.687; p < 0.001), WB (F = 6.736; p < 0.001), cortisol (F = 8.253; p < 0.001) and T:C ratio (F = 3.862; p = 0.01). Conclusion: The behavior of the variables fluctuated with factors such as training load, number of training days and time off, and due to the psychophysiological stress of the match. (AU)

Resumen:	Introduction: Nowadays, female soccer can be considered one of fastest growing sports trends. However, investigations regarding female soccer players' performance are still scarce comparing to male soccer players. The purpose of this study was to compare the athletic profile of female soccer players from adult and youth categories of a professional soccer club. Material and methods Forty-two female soccer players from a professional soccer club were recruited for this investigation (adult category n = 21; youth category n = 21). Performance tests were randomly assigned. Aerobic capacity, sprint, change-of-direction ability, and power performance were assessed. Results There were no significant differences between groups for any of the proposed parameters. Also, better unilateral jump performance for the right leg was observed among adult players (p = 0.05). Conclusions The study suggests that there is no clear discrepancy between youth and adult categories regarding power, sprint, change-of-direction ability, and aerobic performance. However, a trend towards lower limb asymmetry was observed among adult players. (AU)
