“…5 A correlation between the individual changes in maximal isometric force after the 21-week strength-training period and the mean values of serum basal testosterone concentrations during the training period in SA (r=0.84,P<01,n=8) decrease in basal testosterone and FT concentrations in SA during the last training cycle from week 14 to week 21 may be associated to the decrease observed in the training volume. These findings are in line with previous data by Ha¨kkinen et al (1987Ha¨kkinen et al ( , 1988 showing serum testosterone concentrations to differ with regard to the volume and/or intensity of the strength training periods. The correlation observed between T concentrations and the changes in isometric strength (Fig.…”

“…The changes in the volume of strength training have led to changes in serum total testosterone/ cortisol (T/C) ratio with a concomitant change in serum LH concentrations. Furthermore, the T/SHBG ratio has been shown to correlate to strength performance in elite weightlifters in a previous study of Ha¨kkinen et al (1987). Periodical changes in T concentrations seem to occur during the most intense training periods of prolonged strength training (Ha¨kkinen et al 1988).…”

Hormonal and neuromuscular adaptations to strength training were studied in eight male strength athletes (SA) and eight non-strength athletes (NA). The experimental design comprised a 21-week strength-training period. Basal hormonal concentrations of serum total testosterone (T), free testosterone (FT) and cortisol (C) and maximal isometric strength, right leg 1 repetition maximum (RM) of the leg extensors were measured at weeks 0, 7, 14 and 21. Muscle cross-sectional area (CSA) of the quadriceps femoris was measured by magnetic resonance imaging (MRI) at weeks 0 and 21. In addition, the acute heavy resistance exercises (AHRE) (bilateral leg extension, five sets of ten RM, with a 2-min rest between sets) including blood samples for the determination of serum T, FT, C, and GH concentrations were assessed before and after the 21-week training. Significant increases of 20.9% in maximal force and of 5.6% in muscle CSA in NA during the 21-week strength training period were greater than those of 3.9% and -1.8% in SA, respectively. There were no significant changes in serum basal hormone concentrations during the 21-week experiment. AHRE led to significant acute decreases in isometric force and acute increases in serum hormones both at weeks 0 and 21. Basal T concentrations (mean of 0, 7, 14 and 21 weeks) and changes in isometric force after the 21-week period correlated with each other (r=0.84, P<0.01) in SA. The individual changes in the acute T responses between weeks 0 and 21 and the changes in muscle CSA during the 21-week training correlated with each other (r=0.76, P<0.05) in NA. The correlations between T and the changes in isometric strength and in muscle CSA suggest that both serum basal testosterone concentrations and training-induced changes in acute testosterone responses may be important factors for strength development and muscle hypertrophy.

“…Although not significant, SHBG concentrations tended to increase more in the P group, which may have been due to the need to increase the carrying capacity of testosterone stimulated by a reduced availability of free testosterone. It has been previously shown that free testosterone also decreases when the volume anday/or intensity are significantly increased (Ha¨kkinen et al 1987;Ha¨kkinen and Pakarinen 1991).…”

To determine the effects of creatine supplementation during short-term resistance training overreaching on performance, body composition, and resting hormone concentrations, 17 men were randomly assigned to supplement with 0.3 g/kg per day of creatine monohydrate (CrM: n=9) or placebo (P: n=8) while performing resistance exercise (5 days/week for 4 weeks) followed by a 2-week taper phase. Maximal squat and bench press and explosive power in the bench press were reduced during the initial weeks of training in P but not CrM. Explosive power in the bench press, body mass, and lean body mass (LBM) in the legs were augmented to a greater extent in CrM ( P

“…During these periods, the serum testosterone/SHBG ratio increased significantly (P≤0.01). The individual changes during this preparatory 4-week training before the primary competition in serum testosterone/SHBG ratio and the individual changes in the weightlifting result in the clean and jerk lift correlated significantly with each other (R = 0.68; P≤0.05) (Häkkinen, et al 1987).…”

The purpose of this study was to determine the effects of increasing training volume on improvements in per- squat (130.36±56.79 vs. 125.89±57.48 vs. 163.07±101.90 kg; P≥0.05).The data showed that performing additional session per day of high intensity weightlifting training does not lead to significantly greater improvements in performance of young elite weightlifters. Therefore, coaches could use one instead of two sessions of high intensity lifting training per day.
