Medial tendon forces were significantly higher than lateral (23.2 \u00b1 6.6%; P \u2264 0.05) when only the gastrocnemius medialis was subjected to force. Lateral forces were significantly higher when both gastrocnemii (30.6 \u00b1 16.5%) or all three muscles (20.7 \u00b1 10.9%) were loaded. Experimental identification of force concentrations in the human Achilles tendon contributes to the understanding of the origin of its injury.<\/jats:p>","DOI":"10.1177\/107110079902000709","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:31:12Z","timestamp":1362281472000},"page":"444-449","source":"Crossref","is-referenced-by-count":60,"title":["Asymmetrical Loading of the Human Triceps Surae: I.
