Goal shooting technique is critical to shooting success. Several factors influence the success of a shot, including time, distance from the goal post, level of defense, joint angles, and range of motion. This study focused on the kinematic aspects, such as joint angles and range of motion at key positions throughout the shooting task. An additional variable examined was the time taken to complete the shot. By observing these variables, we aimed 1) to explore whether there was kinematic variability between successful and unsuccessful shots and if there were optimal ranges of motion for various joint angles that could improve the success rate of shots; 2) observe if there were kinematic differences between Goal Attack and Goal Shooter, and 3) determine possible associations between limb length and shooting success. Fifteen senior-level female netball shooters (age 21.6±2.6 years; stature: 173±5.9 cm; body mass: 70.48±12.92 kg; shooting experience 9.55±5.2 years) participated in the study. Each participants completed a goal shooting trial with 16 shots from a distance of 2.45m from the goal post, with a minimum of eight successful shots. Sagittal plane kinematics were captured using a full body inertial measurement unit setup (200 Hz, MyoMotion, Noraxon, USA). Eight successful shots and all the unsuccessful shots were analyzed for each participant. The data were smoothed using a low pass Butterworth bidirectional filter with a cut-off frequency of 12 Hz. The filtered data was exported and converted to an Excel sheet and sorted according to key positions. The data comparisons were done using mixed model ANOVA and followed with a Fisher's least significant difference (LSD) post hoc test. Correlations were investigated using Spearman correlation analysis. Significance was determined as p<0.05. Significant differences were revealed between Successful and unsuccessful shots at various joints, predominantly in at the PREP_START_ or in the preparatory phase. The first null hypothesis was rejected, as kinematic differences were found between successful and unsuccessful shots across different joints. The second null hypothesis was rejected, because kinematic differences in joint angles between Goal Attack and Goal Shooter were revealed. Lastly, the third hypothesis was rejected as significant correlations were found between accuracy and limb length. In summary, the primary findings highlighted that kinematic differences between successful and unsuccessful shots at goal were primarily associated with the set-up (preparation phase) and movement of the shooting arm. Future research can further investigate possible differences in coaching philosophies regarding the “correct” shooting technique. AFRIKAANSE OPSOMMING: Beperkte navorsing oor doelgooi in netbal is tot op hede uitgevoer. Doelgooi-tegniek word as ’n kritieke bepaler van doelsukses beskou. Verskeie faktore beïnvloed die uitkoms van ’n doelpoging, insluitend tydsverloop, afstand vanaf die doelpaal, vlak van verdediging, gewrigshoeke en bewegingsomvang. Hierdie studie het spesifiek op die kinematiese aspekte van die beweging gefokus, naamlik die gewrigshoeke en bewegingsomvang by sleutelposisies gedurende die doelaksie. ’n Addisionele veranderlike wat ondersoek is, was die tydsduur wat benodig is om die doelpoging te voltooi. Deur hierdie veranderlikes te bestudeer, was die doelstellings om: 1) vas te stel of daar kinematiese verskille bestaan tussen suksesvolle en onsuksesvolle doelpogings, en of daar optimale bewegingsomvang vir verskillende gewrigshoeke geïdentifiseer kan word wat die sukseskoers van doelpogings verbeter; 2) te bepaal of daar onderskeid tussen die Hulpdoel en Hoofdoel se bewegingspatrone tydens suksesvolle doelpogings bestaan, en 3) te evalueer of daar ’n verwantskap bestaan tussen ledemaatlengte en doelsukses. Metodologie: Vyftien vroulike netbalspelers op seniorvlak (gemiddelde ouderdom: 21.6±2.6 jaar; gemiddelde lengte: 173±5.9 cm; gemiddelde liggaamsmassa: 70.48±12.92 kg; gemiddelde doel-ouderdom: 9.55±5.2 jaar) het aan die ondersoek deelgeneem. Elke deelnemer het ’n doelgooi-proef afgehandel wat uit 16 skote bestaan het vanaf ’n afstand van 2.45 m van die doelpaal, waarvan ’n minimum van agt suksesvolle pogings vereis is. Kinematiese data in die sagittale vlak is opgeneem met behulp van ’n volledige liggaam Inersiemetings-eenheid (200 Hz; MyoMotion, Noraxon, VSA). Vir elke deelnemer is agt suksesvolle pogings en al die onsuksesvolle pogings geanaliseer. Die data is gefiltreer deur middel van ’n lae-deurgangs Butterworth-tweerigtingfilter met ’n afsnyfrekwensie van 12 Hz, waarna dit uitgevoer en na ’n Excel-lêer omgeskakel is en volgens sleutelposisies gesorteer is. Statistiese analise: Datavergelykings is uitgevoer deur middel van ’n gemengde model-ANOVA, gevolg deur Fisher se kleinste beduidende verskil (LSD) post hoc-toets. Korrelasies is ondersoek met behulp van Spearman-korrelasie-analise. ’n Beduidendheidsvlak van p<0.05 is toegepas. Resultate en gevolgtrekkings: Beduidende verskille is waargeneem tussen suksesvolle en onsuksesvolle skote by verskeie gewrigte, hoofsaaklik tydens die PREP_START- of voorbereidingsfase. Die eerste nulhipotese is verwerp, aangesien kinematiese verskille tussen suksesvolle en onsuksesvolle skote oor verskillende gewrigte heen geïdentifiseer is. Die tweede nulhipotese is verwerp, aangesien beduidende kinematiese verskille in gewrigshoeke tussen Hulpdoel en Hoofdoel aangetoon is. Die derde hipotese is eweneens verwerp, aangesien beduidende korrelasies tussen akkuraatheid en ledemaatlengte gevind is. Ten slotte beklemtoon die bevindings dat kinematiese verskille tussen suksesvolle en onsuksesvolle doelskote hoofsaaklik verband hou met die aanvanklike opstelling (voorbereidingsfase) en die beweging van die doelgooi-arm. Hierdie resultate dra by tot die begrip van die biomeganika van doelgooi in netbal en skep ’n grondslag vir toekomstige ondersoeke wat verskille in afrigtingsfilosofieë ten opsigte van die “korrekte” gooi-tegniek kan verken.
