Journal ArticleDOI
Neuromuscular adaptations during concurrent strength and endurance training versus strength training
Keijo Häkkinen,Markku Alen,William J. Kraemer,Esteban M. Gorostiaga,Mikel Izquierdo,Heikki Rusko,Jussi Mikkola,Arja Häkkinen,Heli Valkeinen,E. Kaarakainen,S. Romu,V. Erola,Juha P. Ahtiainen,L. Paavolainen +13 more
TL;DR: The present results suggest that even the low-frequency concurrent strength and endurance training leads to interference in explosive strength development mediated in part by the limitations of rapid voluntary neural activation of the trained muscles.
Journal ArticleDOI
Selective muscle hypertrophy, changes in EMG and force, and serum hormones during strength training in older women.
TL;DR: Both neural adaptations and the capacity of skeletal muscle to undergo training-induced hypertrophy even in older women explain the strength gains.
Journal ArticleDOI
Heterogeneity in resistance training-induced muscle strength and mass responses in men and women of different ages
Juha P. Ahtiainen,Simon Walker,Heikki Peltonen,J. Holviala,Elina Sillanpää,Laura Karavirta,Janne Sallinen,Jussi Mikkola,Heli Valkeinen,Antti A. Mero,Juha J. Hulmi,Keijo Häkkinen +11 more
TL;DR: In this article, the authors quantify high and low responders for RT-induced changes in muscle size and strength and examine possible effects of age and sex on these responses, and conclude that the muscle sizes and strength responses varied extensively between the subjects regardless of subject's age or sex.
Heterogeneity in resistance training-induced muscle strength and mass responses in men and women of different ages
Juha P. Ahtiainen,Simon Walker,Heikki Peltonen,J. Holviala,Elina Sillanpää,Laura Karavirta,Janne Sallinen,Jussi Mikkola,Heli Valkeinen,Antti A. Mero,Juha J. Hulmi,Keijo Häkkinen +11 more
TL;DR: The muscle size and strength responses varied extensively between the subjects regardless of subject’s age and sex, and whether these changes are associated with functional capacity and metabolic health improvements due to RT requires further studies.
Journal Article
Effects of strength training on muscle strength, cross-sectional area, maximal electromyographic activity, and serum hormones in premenopausal women with fibromyalgia.
Keijo Häkkinen,Arto Pakarinen,Pekka Hannonen,Arja Häkkinen,Olavi Airaksinen,Heli Valkeinen,Markku Alen +6 more
TL;DR: Both the magnitude and time course of adaptations of the neuromuscular system to resistance training in women with FM were completely comparable to those taking place in healthy women.
