Fifty\u2010five healthy, untrained participants (age 32\u2009\u00b1\u20095\u2009years) were randomized to periodic (PRT, <jats:italic>n<\/jats:italic>\u2009=\u200920 completed the study, 45% females) or continuous (CRT, <jats:italic>n<\/jats:italic>\u2009=\u200922 completed the study, 45% females) groups. PRT completed a 10\u2010week RT, a 10\u2010week detraining, and a second identical 10\u2010week RT. CRT began with a 10\u2010week non\u2010RT, followed by a 20\u2010week RT. RT included twice\u2010weekly supervised whole\u2010body RT sessions. Leg press (LP) and biceps curl (BC) one repetition maximum (1RM), countermovement jump (CMJ) height, muscle cross\u2010sectional area (CSA) of vastus lateralis (VL), and biceps brachii (BB) using ultrasound imaging were measured twice at the beginning and every fifth week during the intervention. Both groups increased (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) 1RM in LP and BC, CSA in VL and BB, and CMJ height with no differences between the groups. In PRT, 1RM in LP and BC, CSA in VL and BB, and CMJ height decreased during detraining (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). During the first 5\u2009weeks of retraining in PRT, increases in LP 1RM, and VL and BB CSA were greater than in CRT during Weeks 10\u201315 of their CRT (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). PRT and CTR ended up in similar postintervention adaptations, as decreased muscle strength and size during detraining in PRT regained rapidly during retraining. Our results therefore suggest that trainees should not be too concerned about occasional short\u2010term training breaks in their daily lives when it comes to lifelong strength training.<\/jats:p><jats:p><jats:bold>Trial Registration:<\/jats:bold> <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\"
