Progressive overload without progressing load? The effects of load or repetition progression on muscular adaptations.
Plotkin D, Coleman M, Van Every D, Maldonado J, Oberlin D, Israetel M, Feather J, Alto A, Vigotsky AD, Schoenfeld BJ. Plotkin D, et al. PeerJ. 2022 Sep 30;10:e14142. doi: 10.7717/peerj.14142. eCollection 2022. PeerJ. 2022. PMID: 36199287 Free PMC article. Clinical Trial.
We assessed one repetition maximum (1RM) in the Smith machine squat, muscular endurance in the leg extension, countermovement jump height, and muscle thickness along the quadriceps and calf muscles. ...No other notable between-group differences were found across outcomes ( …

A cockroach that jumps.
Picker M, Colville JF, Burrows M. Picker M, et al. Biol Lett. 2012 Jun 23;8(3):390-2. doi: 10.1098/rsbl.2011.1022. Epub 2011 Dec 7. Biol Lett. 2012. PMID: 22158737 Free PMC article.
The large hind legs have grooved femora into which the tibiae engage fully in advance of a jump, and have resilin, an elastic protein, at the femoro-tibial joint. The extensor tibiae muscles contracted for 224 ms before the hind legs moved, indicating that energy must be s …

The Effects of Eccentric Contraction Duration on Muscle Strength, Power Production, Vertical Jump, and Soreness.
Mike JN, Cole N, Herrera C, VanDusseldorp T, Kravitz L, Kerksick CM. Mike JN, et al. J Strength Cond Res. 2017 Mar;31(3):773-786. doi: 10.1519/JSC.0000000000001675. J Strength Cond Res. 2017. PMID: 27787464 Clinical Trial.
Mike, JN, Cole, N, Herrera, C, VanDusseldorp, T, Kravitz, L, and Kerksick, CM. ...For all performance data, significant group time (G T) interaction effects were found for average power production across all 3 sets of a squat jump protocol (p = 0.04) while vertical …

Power and maximum strength relationships during performance of dynamic and static weighted jumps.
Stone MH, O'Bryant HS, McCoy L, Coglianese R, Lehmkuhl M, Schilling B. Stone MH, et al. J Strength Cond Res. 2003 Feb;17(1):140-7. doi: 10.1519/1533-4287(2003)017<0140:pamsrd>2.0.co;2. J Strength Cond Res. 2003. PMID: 12580669
A maximum effort was made for each trial; subjects performed jumps (feet left the floor) with weights up to approximately 90% of 1RM. Squat-jump power was determined using the V-scope 120. Results indicate strong correlations (r = 0.77-0.94) between the 1RM squat and both …

Weakness in end-range plantar flexion after Achilles tendon repair.
Mullaney MJ, McHugh MP, Tyler TF, Nicholas SJ, Lee SJ. Mullaney MJ, et al. Am J Sports Med. 2006 Jul;34(7):1120-5. doi: 10.1177/0363546505284186. Epub 2006 Feb 13. Am J Sports Med. 2006. PMID: 16476917
CLINICAL RELEVANCE: Impairments will have functional implications for activities (eg, descending stairs and landing from a jump). Weakness in end-range plantar flexion may be an unrecognized problem after Achilles tendon repair....
