The purpose of this study was to examine the acute hormonal and muscular responses to a strenuous
strength loading [bilateral leg press (LP) 10x10 1RM] followed by loading-specific active (AR, n =
7, LP 10x10x30% 1RM) or passive (PR, n = 11, seated) recovery. The subjects were men age: 26±4
years, height: 174±8 cm, body mass: 75±13 kg. After control measurements, experimental
measurements were conducted at pre and post loading as well as post recovery and next morning. A
significantly higher absolute concentration (p<0.05) of serum luteinizing hormone (LH) was observed
in AR than PR at next morning while no differences were observed in serum testosterone (T), cortisol
(C) or sex hormone binding globulin (SHBG). Significant differences in relative hormonal responses
to the loading were observed at next morning with greater responses observed in AR than in PR in
terms of LH, and T (p<0.05). Maximal bilateral isometric force (MVC) and countermovement jump
height (CMJ) decreased significantly (p<0.001) from the control measurements in both AR and PR
but returned to control levels by next morning. No between group differences were observed in mean
absolute or relative changes in MVC or CMJ. From a hormonal perspective, the present AR method
appears to have had some favorable effects following the strenuous strength loading; however, acute
decreases in muscular force production did not significantly differ between groups. These results
provide insight into the development of training programs that may help to support the performance
of individuals involved in strenuous tasks.

Neuromuscular, hormonal and molecular responses to heavy resistance training in strength trained men : with special reference to various resistance exercise protocols, serum hormones and gene expression of androgen receptor and insulin-like growth factor-I
Ahtiainen, Juha (University of Jyväskylä, 2006)The present study was designed to obtain more information on mechanisms leading to muscle hypertrophy by determination of the effects of different heavy resistance exercise protocols on acute and chronic neuromuscular and ... -
Acute hormonal and muscular responses and recovery : chronic adaptations to single session combined strength and endurance training with regard to order effect
Eklund, Daniela (2012)Combining both strength (S) and endurance (E) exercise loadings into a single training session can be considered to be of interest e.g. for time management purposes. However, the first loading in a combined session tends ... -
Acute Floatation-REST Improves Perceived Recovery After a High-Intensity Resistance Exercise Stress in Trained Men
Caldwell, Lydia K.; Kraemer, William J.; Post, Emily M.; Volek, Jeff S.; Focht, Brian C.; Newton, Robert U.; Häkkinen, Keijo; Maresh, Carl M. (Lippincott Williams & Wilkins, 2022)Purpose The aim of the present investigation was to determine whether a one-hour floatation-REST session could augment recovery from high-intensity resistance exercise (6 x10 back squats, 2 minutes rest) known to induce ... -
Effects of Acute Loading Induced Fatigability, Acute Serum Hormone Responses and Training Volume to Individual Hypertrophy and Maximal Strength during 10 Weeks of Strength Training
Räntilä, Aapo; Ahtiainen, Juha P.; Häkkinen, Keijo (Uludag University, 2023)This study investigated whether a strength training session-induced acute fatigue is related to individuals’ strength training adaptations in maximal force and/or muscle hypertrophy, and whether acute responses in serum ... -
Acute neuromuscular and endocrine responses and recovery to single session combined endurance and strength loadings: ‘Order effect’ in untrained young men.
Schumann, Moritz; Eklund, Daniela; Taipale, Ritva; Nyman, Kai; Kraemer, William J; Häkkinen, Arja; Izquierdo, Mikel; Häkkinen, Keijo (Lippincott Williams & Wilkins, 2013)The purpose of this study was to investigate acute neuromuscular and endocrine responses and recovery to a single session of combined endurance and strength loading using two loading orders. Forty-two men were demographically ...
