To date, no longitudinal studies exist to\n                    support it use. This investigation examined the effects of retrograde training\n                    on lower body strength and power in recreational athletes aged 18\u201350\n                    years over 6 weeks. Thirty-seven subjects were divided into two groups. Group 1\n                    performed retrograde training 3 days\u2219wk\u22121 using\n                    treadmill speeds, grades and bout durations ranging from\n                        1.6\u20134.9\u2009m\u2219sec\u22121,\n                    2.5\u201327.5% and 10\u201330\u2009seconds, respectively (RG,\n                    n=19). Group 2 was a control group who continued their normal training\n                    (CON, n=18). Pre- and posttests assessed a variety of unilateral and\n                    bilateral measures including vertical and linear jumps, one repetition maximum\n                    leg press strength, and positive and negative power during weighted squat\n                    jumping on a horizontal leg press with a force plate. RG improved significantly\n                    in all tests (P&lt;0.05). Mean effect size (ES) of the relative improvement\n                    in a majority of tests revealed a moderate to very large ES of RG training (ES\n                    range: 0.77\u20132.71). We conclude retrograde training effective for\n                    improving lower body strength and power in recreational athletes.<\/jats:p>","DOI":"10.1055\/a-1796-7808","type":"journal-article","created":{"date-parts":[[2022,12,2]],"date-time":"2022-12-02T00:00:11Z","timestamp":1669939211000},"page":"215-223","source":"Crossref","is-referenced-by-count":0,"title":["Retrograde
