Sports, along with nearly all facets of life, have been impacted by the COVID-19 pandemic. The National Basketball Association quickly adopted a unique method to finish the 2019–2020 regular season and playoffs. The entire league quarantined for months in what was known as the “NBA bubble” where games were played in spectator-less arenas. During this time, increases in shooting accuracy were reported, suggesting that free throws and field goals were made at record-breaking levels. This study examined differences in free throw shooting accuracy with and without spectators. Archival data were retrieved and analyzed to evaluate the potential differences. Free throw shooting accuracy with and without spectators were examined in multiple analyses. Our examination revealed free throw percentages were significantly greater in spectator-less arenas compared with the 2018 and 2019 seasons with spectators. Changes of the environmental characteristics, due to spectator-less arenas, were likely contributors to the improved free throw phenomenon reported in this study.

This study aims to investigate the effect of age and urban and rural living environments on children’s actual and perceived motor competence. To that end, 320 female students aged 8–12 years were selected through random cluster sampling. The perceived motor competence of the participants was assessed using Marsh’s Physical Self-Description Questionnaire, and their actual motor competence was measured by the Test of Gross Motor Development-3. The results showed significant differences between urban and rural girls in perceived and actual motor competence (p < .05). However, age did not make any significant difference in motor competence (p > .05). The most significant differences in actual and perceived motor competence between urban and rural girls were observed in girls aged 8 and 10 (p < .05). The findings also indicated that rural children performed better in actual motor skills, especially ball skills. Therefore, based on the findings, it was concluded that the rural environment could have a greater impact on actual motor competence.

The aim of this study was to describe how major leg muscle activities are altered after learning a novel one-legged pedaling task. Fifteen recreational cyclists practiced one-legged pedaling trials during which they were instructed to match their applied pedal force to a target direction perpendicular to the crank arm. Activity in 10 major leg muscles was measured with surface electromyography electrodes. Improved upstroke task performance was obtained by greater activity in the hip and ankle flexor muscles, counteracting the negative effects of gravity. Greater quadriceps activities explained improved targeting near top dead center. Reduced uniarticular knee and ankle extensor downstroke activities were necessary to prevent freewheeling. Greater hamstring and tibialis anterior activities improved targeting performance near the bottom of the pedal stroke. The activity patterns of the biarticular plantarflexors changed little, likely due to their contributions as knee flexors for smooth upstroke pedaling motion. These results add to our understanding of how the degrees of freedom at the muscle level are altered in a cooperative manner to overcome gravitational effects in order to achieve the learning goal of the motor task while satisfying multiple constraints—in this case, the production of smooth one-legged pedaling motion at the designated mechanical task demands.

Aims: The American Academy of Pediatrics recommends “parents to incorporate supervised, awake ‘prone play’ in their infant’s routine to support motor development and minimize the risk of plagiocephaly”. The purpose of this feasibility study was to compare usual care to a reward contingency–based intervention, developed to increase prone tolerance and improve motor skills. Methods: Ten full-term infants, 3–6- months old, with poor prone tolerance were randomized to either the Education group or Reward contingency group. Each group participated in three parent education sessions and 15 intervention sessions, over the period of three weeks. Infants in the Reward contingency group used the Prone Play Activity Center, a technology developed to reinforce motor behavior of infants in prone position. Intervention frequency and parent feedback data determined the feasibility of the interventions. Results: Infants in the Reward contingency group practiced a median of 12 of the 15 anticipated intervention sessions in the Prone Play Activity Center. These infants used the device for a mean of 18 minutes per day. Parents of infants in the Education group practiced a median of 10 sessions of the 15 anticipated intervention sessions. Conclusion: The reward contingency–based intervention is feasible for use in a future clinical trial with some modifications.

The motor and social skill difficulties experienced by many children with autism spectrum disorder (ASD) can create challenges when participating in age appropriate physical activity contexts. Although behavioral interventions can increase the general social communicative skills of children with ASD, often the skills targeted are not relevant to physical activity contexts. Thus, this pilot study utilized a movement-based intervention program to support children with ASD in learning both social and movement skills that are relevant to physical activity contexts. Nineteen children with ASD with a mean age of 9.3 (±3.0) years participated in this program for 8 weeks, twice a week, at a recreation center as an afterschool activity. Six object control skills were selected and tested before and after the intervention because these gross motor skills were considered to elicit human interactions and place demands on social skills. Ten social skills were selected, aligned to each program context, taught, and evaluated. This intervention resulted in significant improvements in object-control skills for the participants. Additionally, there were significantly more participants who demonstrated improvements in their performance of the target social skills than who did not demonstrate improvements. These preliminary findings provide support for the feasibility of developing interventions that address social skill deficits in the context of physically active settings for children with ASD.

Introduction: The Common Region Test (CRT) is useful for predicting children’s visual memory as individual object-place binding predicted better object memory while objects-region coding predicted better place memory. Aim: To test children with autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) with regards to spatial binding in the CRT. Methods: 19 children with ASD and 20 children with ADHD were gender-matched with 39 typically developing children by chronological age and with another 39 children by verbal mental age as control groups (N = 117) and tested with the CRT and Bender Gestalt test. Results: Children with ASD and ADHD showed more unsystematic coding than typically developing children. This was due to lower fine motor skills, and in children with ADHD also because of reduced verbal naming. Almost all children with ASD presented the less mature under-inclusive Type I unsystematic coding which included object-place binding, while children with ADHD showed the over-inclusive Type II unsystematic coding that was overriding the Gestalt-like properties of proximity and similarity. Conclusions: It was demonstrated that the CRT is a useful screening instrument for ASD and ADHD that shows that their spatial categorization varies in their unsystematic visuo-spatial classification due to fine motor skill deficiencies.

Aim: To analyze the evidence of validity and reliability of the Test of Gross Motor Development, Second Edition (TGMD-2) for low-income preschoolers; and to investigate the associations between the final model with sex, age, and body mass index (BMI). Methods: 368 preschoolers (3–5 years old [M = 4.80, SD = 0.48]; 176 boys) located in deprived areas were assessed for anthropometric measures and motor competence via the TGMD-2. A two-factor model (12 skills) was used and confirmatory indexes were calculated. The Bayesian criteria and the Composite Reliability were employed to evaluate alternative models. Relationships between the final model proposed with age, sex, and BMI were calculated using a network analysis (Mplus 8.0; Rstudio). Results: A two-factor model (locomotion and object control) with adequate values (>0.30) for the six skills (gallop, leap, slide, strike, throw, and roll) presented excellent indexes. Relationships between sex and throwing (r = −.22), and strike (r = −.21), indicated better performance for boys. Positive relationships were found for age with slide (r = 0.23) and hop (r = 0.28), and for BMI with throw (r = 0.18). Conclusion: Validity of a TGMD-2 short version for low-income preschoolers was present. The machine learning analysis to associate fundamental movement skills with gender, age, and BMI seems useful to optimize future interventions.

The quiet eye is a characteristic of highly skilled perceptual and motor performance that is considered as the final fixation toward a target before movement initiation. The aim of this study was to extend quiet eye–related knowledge by investigating expertise effects on overall quiet eye duration among expert and near-expert basketball players, as well as to determine the relative contribution of early and late visual information in a basketball jump shot by comparing the timing components of quiet eye duration (early and late quite eye). Twenty-seven expert and near-expert male basketball players performed the jump shots. Gaze was recorded with the SensoMotoric Instruments eye tracking glasses and shooting performance accuracy was evaluated by scoring each shot on a scale of 1–8. Six infrared cameras circularly arranged around the participants were used to collect the kinematic information of the players. The performance accuracy, gaze behavior, and kinematic characteristics of the participants during the test were calculated. The experts with longer quiet eye duration had better performance in a basketball jump shot compared to the near-experts. Also the experts had longer early and late quiet eye duration than the near-experts. The results revealed a relationship between quiet eye duration and performance. The combined visual strategy is a more efficient strategy in complex far-aiming tasks such as a basketball jump shot.

Changing gait parameters through acoustic feedback is a promising approach in gait therapy. The question remains to what extent, if any, the theories and concepts of motor learning have been taken into account for acoustic feedback systems development. Fifteen studies were identified for further analysis using a scoping review framework, among which seven had individuals with disordered gait as their population and eight incorporated healthy individuals. It was found that most studies used error feedback and did not test for long-term effects on gait parameters. It can be concluded that future studies should apply motor learning theories and concepts to the development of acoustic feedback devices for gait therapy.
