We aimed to compare the effects of periodic resistance training (RT) and continuous RT on muscle strength and size. Fifty-five healthy, untrained participants (age 32 ± 5 years) were randomized to periodic (PRT, n = 20 completed the study, 45% females) or continuous (CRT, n = 22 completed the study, 45% females) groups. PRT completed a 10-week RT, a 10-week detraining, and a second identical 10-week RT. CRT began with a 10-week non-RT, followed by a 20-week RT. RT included twice-weekly supervised whole-body RT sessions. Leg press (LP) and biceps curl (BC) one repetition maximum (1RM), countermovement jump (CMJ) height, muscle cross-sectional 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 (p < 0.001) 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 (p < 0.05). During the first 5 weeks of retraining in PRT, increases in LP 1RM, and VL and BB CSA were greater than in CRT during Weeks 10–15 of their CRT (p < 0.01). 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-term training breaks in their daily lives when it comes to lifelong strength training.

High Responders to Hypertrophic Strength Training Also Tend to Lose More Muscle Mass and Strength During Detraining Than Low Responders
Räntilä, Aapo; Ahtiainen, Juha P.; Avela, Janne; Restuccia, Joel; Kidgell, Dawson; Häkkinen, Keijo (Lippincott Williams & Wilkins, 2021)This study investigated differences in individual responses to muscle hypertrophy during strength training and detraining. Ten weeks of resistance training was followed by 6 weeks of detraining in men (n 5 24). Bilateral ... -
Training load does not affect detraining's effect on muscle volume, muscle strength and functional capacity among older adults
Roie, Evelien Van; Walker, Simon; Driessche, Stijn Van; Baggen, Remco; Coudyzer, Walter; Bautmans, Ivan; Delecluse, Christophe (Elsevier Inc., 2017)Research underlines the potential of low-load resistance exercise in older adults. However, while the effects of detraining from high-load protocols have been established, it is not known whether gains from low-load training ... -
Heterogeneity in resistance training induced muscle strength and mass responses in the upper and lower extremities
Ylijärvi, Sara (2023)It has been reported that some muscle groups may demonstrate higher strength and hypertrophic gains in response to resistance training than others. In addition to this, the gains in strength and muscle size are highly ... -

Stimuli and sensors that initiate skeletal muscle hypertrophy following resistance exercise
Wackerhage, Henning; Schoenfeld, Brad J.; Hamilton, D. Lee; Lehti, Maarit; Hulmi, Juha (American Physiological Society, 2019)One of the most striking adaptations to exercise is the skeletal muscle hypertrophy that occurs in response to resistance exercise. A large body of work shows that a mammalian target of rapamycin complex 1 (mTORC1)-mediated ...
