    The development of Fundamental Movement Skills (FMS) and physical literacy (PL) are relatively new concepts in physical education. In this research paper, a novel method of teaching FMS and PL are explored using an Eastern philosophical approach to human movement. Overhand throwing was the FMS chosen for the study. As part of the process a model for understanding Eastern philosophy to human movement was developed and then a throwing curriculum integrating the model was created and compared with a Western approach using teaching game for understanding (TGfU). Grade two students were taught using one of the two approaches. The Eastern philosophical model incorporated four components: (1) visualization and observational skill development; (2) incorporation of technique, accuracy, speed and power (TASP) as a unifying principle where order of each factor is crucial; (3) bilateral body development using both sides of the body; and (4) peer-to-peer learning. To measure throwing technique, different throwing protocols were examined and intra and inter rater reliability were assessed. Based on the results, a new throwing protocol was established for use in the main study. This research was a true experimental randomized controlled trial (RCT), a multi-factor and multi-variable repeated measure designed with 84 grade two students. The independent variables included pre-, post-, and follow-up testing; bilaterality which involved the dominant and non-dominant hands; and groups (Eastern philosophical approach, traditional Western approach, and two delayed control groups). Dependent variables were technique, accuracy, speed, and power (TASP), and attitude. When results were compared between the Eastern and Western groups, both groups improved overall. In regards to technical ability, the Eastern group was significantly higher than the Western group for the non-dominant hand. In contrast, the Western group was significantly higher than the Eastern group for the dominant hand. The Eastern group’s accuracy was significantly higher than the Western group for both hands. While not statistically significant, the percentage of improvement showed that the Eastern group improved more than the Western group in TASP except for technique when using the dominant hand. There were some inconsistencies that were difficult to explain including the control group having significantly higher improvement on accuracy than either of the experimental groups. Students had four half hour lessons to learn to throw. The Western group focused on throwing with the dominant hand. During the same half hour of each lesson, the Eastern group worked equally with both the dominant and non-dominant hands. Following the study, the two delayed control groups were randomly assigned to either the Eastern or Western approach. Results from this study were inconsistent with the main study with many significant results, some supporting the Eastern approach and some supporting the Western approach. Possible explanations for this discrepancy are examined in the discussion. Based on the results, it would appear that the Eastern philosophical approach to teaching throwing has potential to improve children’s throwing ability. Future research is needed to determine what aspects of the Eastern philosophical approach have greatest impact on learning. It may be possible to apply this model to other fundamental movement skills (FMS) such as kicking and jumping to improve children’s physical literacy. An Eastern approach to human movement may have values with other participants including seniors. Perhaps integrating the best features of both Western and Eastern approaches would be optimal for improving performance.

    Impact of Bilateral Training on Overhand Throwing Performance: Speed, Accuracy, Technique, and Upper-body Kinematics
    (2021-01) Weisberg, Alanna Danielle; Katz, Larry; Lee, Hyun Suk; McDonough, Meghan H.; Paskevich, David M.
    Manuscript 1: The Sport Technology Research Lab developed an overhand throwing, eight task-component rubric designed to be used in multiple populations. This study assessed its inter-rater and intra-rater reliability. Three groups of raters, two individuals and one panel of three (consensus panel), assessed 480 video recorded overhand throws conducted by healthy adults. Individual raters assessed all videos twice with two weeks between the sessions. The consensus panel assessed all throws once. An ICC 2,k from aggregated data, independent t-tests, KR-20 and percentage agreements were conducted to assess reliability. Independent t-tests showed a significant difference between individual raters and the consensus panel, where the consensus panel scored performance significantly lower. KR-20 and percentage agreements demonstrated high reliability total scores, and moderate-high reliability for the eight task components. ICC 2,k showed high total reliability, suggesting the rubric is a reliable scale when evaluating the overhand throw in adults. However, inconsistencies in individual task components need to be addressed before the scale is used. Manuscript 2: The overhand throw is a complex whole-body motor skill that is fundamental to many sports and activities. The primary outcomes of the overhand throw are ball speed and accuracy. The momentum generated to complete the movement begins in the lower body and transfers through the trunk to the throwing arm. This study’s primary purpose was to evaluate the impact of the non-throwing arm on the ball speed during an overhand throw with both the dominant and non-dominant arms. Eighteen participants (age: 20.20±2.90 yrs., nine females) were divided into two intervention groups: a pulling group taught to engage the non-throwing arm through a pull towards the body, and a non-pulling group taught the overhand throw using a component-based physical education curriculum. Each participant completed 24 total throws, twelve for each side (dominant and non-dominant arm). Ball speed and kinematic data were collected using an eight-camera motion analysis system and were assessed using a pre-post study design. Throwing with both the dominant and non-dominant arms resulted in improvement in both training groups, but there was a much higher Cohen’s D effect size for increased ball velocity when the non-throwing arm was engaged.
