“…Place and colleagues (2007) observed high levels of absolute reliability with an ICC of .90 and a coefficient of variation (CV) of 3.5% for quadriceps IMVC torque with a typical error lower than 5%, and confirmed the validity of the test. Neuromuscular assessments based on IMVC performed in the lower limbs have been demonstrated to have adequate applicability in a sample of goalball players, thus allowing the identification of neuromuscular fatigue (Cursiol et al, 2022). The strong correlation (r = .75) identified by Goulart-Siqueira and colleagues (2019) between VBALL and countermovement jump in simulated goalball penalty shots indicate lower limb strength is essential for faster throws.…”

This study evaluated the influence of acute fatigue on shooting skill performance in goalball penalty shots. Eleven sub-elite male players were evaluated in an official court using a two-dimensional procedure (60 Hz) to compute the mean radial error, bivariate variable error and accuracy, and three-dimensional kinematics (240 Hz) to measure ball velocity. Rating of perceived exertion, blood lactate concentration and knee extension isometric maximal voluntary contractions were assessed at rest and immediately after the completion of an incremental test specific to goalball. Although significant differences were observed for rating of perceived exertion (pre: M = .36 AU, SD = .67; post: M = 9.27 AU, SD = .79), blood lactate concentration (M = 1.33 mM, SD = .51; M = 9.04 mM, SD = 2.25) and peak force (M = 597.85 N, SD = 132.35; M = 513.37 N, SD =107.00) at the end of the incremental test, no differences were identified in the pre and post moments for mean radial error (M = .10 m, SD = 1.01; M =.37 m, SD = 2.19), bivariate variable error (M = 3.56 m, SD = .70; M = 3.25 m, SD = .70), accuracy (M = 3.68 m, SD = .74; M = 3.78 m, SD = 1.13) and ball velocity (M = 18.53 m . s -1 , SD = 1.53; M =18.46 m . s -1 , SD = 1.65). We concluded that even though significant levels of fatigability can be attributed to the incremental test specific to goalball, shooting skill performance in goalball penalty shots does not appear to be affected. However, further investigations are needed so that goalball coaches can develop strategies that contribute to improve performance in this technical action. Such improvements are decisive for the outcome of a match.

Goalball is a Paralympic team sport designed specifically for people with visual impairments. This study aimed to investigate goalball athletes’ perceptions of the coaching behaviors of their coaches. A total of 35 goalball athletes (12 female, 23 male) participated in the study, completing the Coaching Behavior Scale for Sport comprised of 47-items across seven constructs: physical training and conditioning, technical skills, mental preparation, goal setting, competition strategies, personal rapport, and negative personal rapport. Descriptive statistics for each subscale were calculated across different demographic groups. Negative personal rapport had the highest mean among all constructs (M = 6.30, SD = .59) and goal setting being the lowest (M = 4.32, SD = 1.64). A Mann–Whitney U test compared mean differences between age, gender, training frequency, and prior coaching experience. No statistically significant differences were found between groups. The findings showed positive perceptions toward coaches’ behaviors, with frequent engagement identified in areas of personal rapport, competition strategies, and technical skills. However, athletes perceived physical training and goal setting as areas of less involvement from their coaches. This suggests a disconnection in coaches’ engagement with athletes’ objective-setting processes and physical preparation. Future research directions and limitations were also discussed.

Research has yet to explore the long-term influences of physical fitness parameters on goalball and how COVID-19 affected athletes’ training program. This study evaluated the longitudinal changes in body composition (BC), postural balance (PB), maximal isometric grip force (MIGF), vertical jump (countermovement (CJ), squat jump (SJ), and peak oxygen consumption (VO2peak) in seven male Paralympic goalball athletes preparing for the Tokyo 2020 Paralympics. Six measurements were performed three times ([first] pre-lock down: January 2020, [second] post-lock down: September 2020, and [third] final follow-up: June 2021) on a variable-by-variable basis. Post hoc tests showed a significant improvement in BC at the third time point compared to the first and second time points. Concomitantly, PB and MIGF were significantly improved at the third time point compared to the first and second time points, respectively. A significant decline was observed in CJ and SJ heights at the second time point compared to the first time point whereas SJ height increased at the third time point compared to the second time point. No change was observed in CJ height at the third time point versus the second time point. There was a dramatic reduction in VO2peak at the second time point compared to the first time point. No change was observed in VO2peak occurred at the third time point versus pre and post lock down. Even with the disruption in the annual training plan due to COVID-19 pandemic, our participants maintained physical fitness levels with home-based exercises.
