We designed three alternative indices to adjust for this anthropometric bias: (1) multiplying <em>MBT<\/em><sub><em>T<\/em><\/sub> by the height-to-mass ratio (<em>MBT<\/em><sub><em>A1<\/em><\/sub>), (2) dividing <em>MBT<\/em><sub><em>T<\/em><\/sub> by the product of mass and height (<em>MBT<\/em><sub><em>A2<\/em><\/sub>), and (3) dividing <em>MBT<\/em><sub><em>T<\/em><\/sub> by the body mass index (<em>MBT<\/em><sub><em>A3<\/em><\/sub>). Using age- and sex-adjusted LMS-based z-scores from two independent cohorts (821 children, aged 8.3\u2009\u00b1\u20090.7 years; 354 adolescents, aged 14.4\u2009\u00b1\u20092.2 years), we compared the variants\u2019 alignment with the concave BMI-profiles of five standard fitness tests (6-minute run, standing long jump, jump sideways, 4\u2009\u00d7\u200910\u00a0m shuttle run, push-ups). The three anthropometrically enriched variants yielded significantly better goodness of fit than <em>MBT<\/em><sub><em>T<\/em><\/sub> with <em>MBT<\/em><sub><em>A1<\/em><\/sub> performing best overall. Furthermore, when deployed as independent covariates, the enriched indices demonstrated systematically higher predictive power for standard fitness tasks than the unadjusted distance. We recommend adjusting <em>MBT<\/em><sub><em>T<\/em><\/sub> via the height-to-mass ratio for a fairer assessment, though its structural overlap with BMI requires caution in predictive models.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Zusammenfassung<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Der traditionelle Medizinballwurf (<em>MBT<\/em><sub><em>T<\/em><\/sub>) zur Beurteilung der Explosivkraft der oberen Extremit\u00e4ten beg\u00fcnstigt naturgem\u00e4\u00df schwerere und gr\u00f6\u00dfere Teilnehmer. Wir haben drei alternative Indizes entwickelt, um diese anthropometrische Verzerrung auszugleichen: (1) Multiplikation des <em>MBT<\/em><sub><em>T<\/em><\/sub> mit dem Verh\u00e4ltnis von K\u00f6rpergr\u00f6\u00dfe zu K\u00f6rpergewicht (<em>MBT<\/em><sub><em>A1<\/em><\/sub>), (2) Division des <em>MBT<\/em><sub><em>T<\/em><\/sub> durch das Produkt aus K\u00f6rpergewicht und K\u00f6rpergr\u00f6\u00dfe (<em>MBT<\/em><sub><em>A2<\/em><\/sub>) und (3) Division des <em>MBT<\/em><sub><em>T<\/em><\/sub> durch den Body-Mass-Index (<em>MBT<\/em><sub><em>A3<\/em><\/sub>). Anhand von alters- und geschlechtsangepassten, auf LMS basierenden z-Werten aus zwei unabh\u00e4ngigen Kohorten (821 Kinder im Alter von 8,3\u2009\u00b1\u20090,7 Jahren; 354 Jugendliche im Alter von 14,4\u2009\u00b1\u20092,2 Jahren) verglichen wir die \u00dcbereinstimmung der Varianten mit den konkaven BMI-Profilen von f\u00fcnf Standard-Fitnesstests (6-Minuten-Lauf, Standweitsprung, Seitw\u00e4rtssprung, 4\u2009\u00d7\u200910 m Shuttle-Lauf, Liegest\u00fctze). Die drei anthropometrisch angereicherten Varianten ergaben eine signifikant bessere Anpassungsg\u00fcte als der <em>MBT<\/em><sub><em>T<\/em><\/sub> , wobei der <em>MBT<\/em><sub><em>A1<\/em><\/sub> insgesamt am besten abschnitt. Dar\u00fcber hinaus zeigten die angereicherten Indizes, wenn sie als unabh\u00e4ngige Kovariaten eingesetzt wurden, eine systematisch h\u00f6here Vorhersagekraft f\u00fcr Standard-Fitnessaufgaben als die unbereinigte Distanz. Wir empfehlen, den <em>MBT<\/em><sub><em>T<\/em><\/sub> \u00fcber das Verh\u00e4ltnis von K\u00f6rpergr\u00f6\u00dfe zu K\u00f6rpergewicht anzupassen, um eine fairere Bewertung zu erzielen, obwohl seine strukturelle \u00dcberschneidung mit dem BMI bei der Verwendung in Vorhersagemodellen Vorsicht erfordert..<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published \/ Publiziert: 19.06.2026 Die Wurfweite des Medizinballs, gewichtet nach dem Verh\u00e4ltnis von K\u00f6rpergr\u00f6\u00dfe zu K\u00f6rpermasse, steht in Einklang mit anderen Aufgaben zur k\u00f6rperlichen Fitness LINK to the open access publication \/ LINK zur vollst\u00e4ndigen Publikation: DOI: https:\/\/doi.org\/10.1038\/s41598-026-58353-w Abstract The traditional Medicine Ball Throw (MBTT) for assessing upper-extremity explosive strength inherently favours heavier and taller [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_eb_attr":"","ocean_post_layout":"full-screen","ocean_both_sidebars_style":"","ocean_both_sidebars_content_width":0,"ocean_both_sidebars_sidebars_width":0,"ocean_sidebar":"0","ocean_second_sidebar":"0","ocean_disable_margins":"on","ocean_add_body_class":"","ocean_shortcode_before_top_bar":"","ocean_shortcode_after_top_bar":"","ocean_shortcode_before_header":"","ocean_shortcode_after_header":"","ocean_has_shortcode":"","ocean_shortcode_after_title":"","ocean_shortcode_before_footer_widgets":"","ocean_shortcode_after_footer_widgets":"","ocean_shortcode_before_footer_bottom":"","ocean_shortcode_after_footer_bottom":"","ocean_display_top_bar":"off","ocean_display_header":"default","ocean_header_style":"","ocean_center_header_left_menu":"0","ocean_custom_header_template":"0","ocean_custom_logo":0,"ocean_custom_retina_logo":0,"ocean_custom_logo_max_width":0,"ocean_custom_logo_tablet_max_width":0,"ocean_custom_logo_mobile_max_width":0,"ocean_custom_logo_max_height":0,"ocean_custom_logo_tablet_max_height":0,"ocean_custom_logo_mobile_max_height":0,"ocean_header_custom_menu":"0","ocean_menu_typo_font_family":"0","ocean_menu_typo_font_subset":"","ocean_menu_typo_font_size":0,"ocean_menu_typo_font_size_tablet":0,"ocean_menu_typo_font_size_mobile":0,"ocean_menu_typo_font_size_unit":"px","ocean_menu_typo_font_weight":"","ocean_menu_typo_font_weight_tablet":"","ocean_menu_typo_font_weight_mobile":"","ocean_menu_typo_transform":"","ocean_menu_typo_transform_tablet":"","ocean_menu_typo_transform_mobile":"","ocean_menu_typo_line_height":0,"ocean_menu_typo_line_height_tablet":0,"ocean_menu_typo_line_height_mobile":0,"ocean_menu_typo_line_height_unit":"","ocean_menu_typo_spacing":0,"ocean_menu_typo_spacing_tablet":0,"ocean_menu_typo_spacing_mobile":0,"ocean_menu_typo_spacing_unit":"","ocean_menu_link_color":"","ocean_menu_link_color_hover":"","ocean_menu_link_color_active":"","ocean_menu_link_background":"","ocean_menu_link_hover_background":"","ocean_menu_link_active_background":"","ocean_menu_social_links_bg":"","ocean_menu_social_hover_links_bg":"","ocean_menu_social_links_color":"","ocean_menu_social_hover_links_color":"","ocean_disable_title":"on","ocean_disable_heading":"default","ocean_post_title":"","ocean_post_subheading":"","ocean_post_title_style":"","ocean_post_title_background_color":"","ocean_post_title_background":0,"ocean_post_title_bg_image_position":"","ocean_post_title_bg_image_attachment":"","ocean_post_title_bg_image_repeat":"","ocean_post_title_bg_image_size":"","ocean_post_title_height":0,"ocean_post_title_bg_overlay":0.5,"ocean_post_title_bg_overlay_color":"","ocean_disable_breadcrumbs":"off","ocean_breadcrumbs_color":"","ocean_breadcrumbs_separator_color":"","ocean_breadcrumbs_links_color":"","ocean_breadcrumbs_links_hover_color":"","ocean_display_footer_widgets":"off","ocean_display_footer_bottom":"off","ocean_custom_footer_template":"0","iawp_total_views":21,"ocean_post_oembed":"","ocean_post_self_hosted_media":"","ocean_post_video_embed":"","ocean_link_format":"","ocean_link_format_target":"self","ocean_quote_format":"","ocean_quote_format_link":"post","ocean_gallery_link_images":"off","ocean_gallery_id":[],"footnotes":""},"categories":[1,50],"tags":[],"class_list":["post-1217","post","type-post","status-publish","format-standard","hentry","category-allgemein","category-englisch","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.2 -
