Preventive strategies include eccentric\n                        exercises, but the influence of field eccentric exercises on these risk\n                        factors remains unclear. We investigated the influence of a field hamstring\n                        eccentric program on hamstring strength and flexibility. Twenty-seven\n                        amateur athletes were randomly assigned to an intervention (n=13) or\n                        control group (n=14). In the intervention group, participants were\n                        involved in 15 sessions of four eccentric exercises. Peak torque,\n                        hamstring-to-quadriceps ratios, passive and active flexibility were\n                        analyzed. No significant modifications of strength, passive or active\n                        flexibility were observed in the control group (p&gt;0.05). Hamstring\n                        eccentric peak torque (+7.1%) and functional\n                        hamstring-to-quadriceps ratios (9.3%) were significantly increased\n                        (p&lt;0.05) in the intervention group, but not concentric strength\n                        (p&lt;0.05). Passive straight leg raise was significantly increased by\n                        11.4\u00b0 (+12.7%, p&lt;0.001), but not active\n                        flexibility (+3.1%, p&gt;0.05). In conclusion, a 6-week\n                        eccentric program, including four field exercises for hamstring muscles, is\n                        an effective method of improving eccentric strength, functional ratios and,\n                        especially, passive flexibility. As this program may be easily implemented\n                        in a real-world context, this association of multiple eccentric exercises\n                        might be useful in an injury prevention strategy.<\/jats:p>","DOI":"10.1055\/a-1073-7809","type":"journal-article","created":{"date-parts":[[2020,1,14]],"date-time":"2020-01-14T18:39:13Z","timestamp":1579027153000},"page":"233-241","source":"Crossref","is-referenced-by-count":29,"title":["Influence
