Purpose.The purpose of this study was to determine the effects of increasing the volume of weight-training from one to three sets upon body composition and muscular strength.Methods.Sixteen male weight-trainers volunteered to act as subjects and were randomly assigned to one of two training groups. Supervised weight-training targeting the upper body was conducted three times per week for eight weeks using one set (n=8) or three sets (n=8) of six repetitions to fatigue. Subjects were measured before and after the training intervention for (1) strength performance (Nand kg) and (2) adiposity (sum of seven skinfold thicknesses in mm).Results.Both training groups improved significantly (20.7%) in terms of muscular strength (P<0.05) with no differences being observed between the one set (21.98% increase) and three set group (20.71% increase) after the training interventions (P>0.05). Significant decreases were also observed for skinfold measures in the one set group (P<0.05).Conclusions.One set of high intensity resistance training was as effective as three sets for increasing the strength of muscle groups in the upper body. The one set protocol also produced significantly greater decreases in adiposity.

The purpose of this study was to compare different split resistance training routines on body composition and muscular strength in elite bodybuilders. Ten male bodybuilders (26.7 ± 2.7 years, 85.3 ± 10.4 kg) were randomly assigned into one of two resistance training groups: 4 and 6 times per week (G4× and G6×, respectively), in which the individuals trained for 4 weeks, 4 sets for each exercise performing 6–12 repetitions maximum (RM) in a pyramid fashion. Body composition was assessed by dual energy X-ray absorptiometry, muscle strength was evaluated by 1RM bench-press testing. The food intake was planned by nutritionists and offered individually throughout the duration of the experiment. Significant increases (p < .05) in fat-free mass (G4× = +4.2%, G6× = +3.5%) and muscular strength (G4× = +8.4%, G6× = +11.4%) with no group by time interaction were observed. We conclude that 4 and 6 weekly sessions frequencies of resistance training promote similar increases in fat-free mass and muscular strength in elite bodybuilders.

This study investigated the effect of creatine monohydrate (Cr) supplementation on performance and training volume in rowers. Twenty-two rowers trained with continuous and interval rowing and resistance training 4 and 2 days/week, respectively, for 6 weeks. Cr supplementation consisted of a 5-day load (0.3 g/kg−1•day−1) followed by a 5-week maintenance dose (0.03 g/kg−1•day−1) while training. Five days of Cr loading did not change body composition, repeated interval rowing performance, 2,000-m rowing times, or strength performance. Five additional weeks of training with a maintenance dose of Cr or placebo significantly improved body composition, [Formula: see text] 2,000-m rowing times, repeated power interval performance, and strength to a similar extent in both groups. Subjects training with Cr did not perform more repetitions per set of strength exercise nor produce or maintain higher power outputs during repeated rowing sessions. Cr supplementation did not increase performance or training volume over a placebo condition in rowers that performed a combined high intensity rowing and strength program.

Although weight training can enhance muscular strength, power, and body composition, outdated beliefs about muscular adaptations have limited its use in dancers. The purpose of this study was to investigate the effect of an 8-week progressive overload resistance-training (RT) program on muscular strength, power and body composition in collegiate female dancers. Sixteen subjects were randomised into a dance-only control group (CON) or an RT + dance training group (EXP). EXP met 3×/week for RT. Body fat (%BF), lean body mass (LBM), girth measurements, vertical jump (VJ), muscular strength (1-repetition max (RM) squat (SQT) and 1-RM bench press (BP)), maximal oxygen consumption (V̇O2max, and ventilatory threshold (VT)) were assessed pre- and post-study. Baseline performance characteristics across all subjects were: %BF=28.2±5.7%, VJ=33.4±5.4 cm, SQT=57.5±12.1 kg, BP=30.1±7.6 kg, (V̇O2max)=40.6±3.4 ml/kg/min, and VT=71.2±3.4%VO2max. Strength improvements were significantly greater for EXP than CON (P<0.05). No significant differences were found between groups for %BF, LBM, girth measurements, VJheight, (V̇O2max), or VT (P>0.05). However, a trend was observed for VJpower favouring EXP (P=0.07). EXP significantly improved strength, while no significant changes were observed in body composition. However, EXP improved their power-to-weight ratio, which may be a positive performance adaptation. RT for dancers can improve strength and power, allowing enhanced muscular loading and fatigue-resistance, which may optimise performance and decrease injury risk.

Background: Exercise has been shown to reduce adverse outcomes related to breast cancer. However, the rate of adherence to physical exercise is very low among breast cancer survivors (BCS). This study investigated the effects of high supervision ratio resistance training (RT), once a week for 8 weeks, on changes in body composition and muscular strength in BCS. Methods: Twenty-five female BCS undergoing hormone therapy were randomized into resistance training group (TG, n = 12) or control (CG, n = 13) group. The TG performed 8 weeks of supervised RT, with 1 trainer per volunteer, once a week. Body composition was evaluated by dual-energy X-ray absorptiometry, and muscle strength was evaluated by 10 repetition maximum (10 RM) for leg press (45°) and bench press exercises. A 1-way analysis of variance was used to compare within-group effects at pre- and post-intervention. An analysis of covariance test was used to compare post-intervention values, using pre-intervention measures as covariates. The effect size (ES) was calculated by Cohen’s d. Results: The TG improved muscle strength in 10 RM leg press (45°; Δ 33.75 ± 11.51 kg, P = .02; ES = 0.96) and bench press (Δ 4.08 ± 1.83 kg, P = .01; ES = 1.15). Adherence to training was more than 99%. Changes in body composition were not detected. There were no changes in the CG for any assessment. Conclusion: Once-weekly supervised RT could be an alternative to increase the adherence to exercise and improve muscular strength in BCS.

Elevated circulating C-terminal agrin fragment (CAF) is a marker of neuromuscular junction degradation and sarcopenia. This study sought to determine if resistance training (RT) impacted the serum levels of CAF in perimenopausal (PERI-M) and postmenopausal (POST-M) women. A total of 35 women, either PERI-M or POST-M, participated in 10 weeks of RT. Body composition, muscle strength, and serum estradiol and CAF were determined before and after the RT. The data were analyzed with two-way analysis of variance (p ≤ .05). Upper body and lower body strength was significantly increased, by 81% and 73% and 86% and 79% for the PERI-M and POST-M participants, respectively; however, there were no significant changes in body composition. Estradiol was significantly less for the POST-M participants at pretraining compared with the PERI-M participants. CAF moderately increased by 22% for the PERI-M participants in response to RT, whereas it significantly decreased by 49% for the POST-M participants. Ten weeks of RT reduced the circulating CAF in the POST-M women and might play a role in attenuating degenerative neuromuscular junction changes.

Prohormone supplements (PS) are recognized not to impart anabolic or ergogenic effects in men, but the research supporting these conclusions is dated. The Anabolic Steroid Control Act was amended in 2004 to classify androstenedione and 17 additional anabolic compounds as controlled substances. The viability of PS that entered the market after that time have not been evaluated. Seventeen resistance-trained men (23 ± 1 yr; 13.1 ± 1.5% body fat) were randomly assigned to receive either 330 mg/day of 3β-hydroxy-5α-androst-1-en-17-one (Prohormone; n = 9) or sugar (Placebo; n = 8) per os and complete a 4-wk (16 session) structured resistance-training program. Body composition, muscular strength, circulating lipids, and markers of liver and kidney dysfunction were assessed at study onset and termination. Prohormone increased lean body mass by 6.3 ± 1.2%, decreased fat body mass by 24.6 ± 7.1%, and increased their back squat one repetition maximum and competition total by 14.3 ± 1.5 and 12.8 ± 1.1%, respectively. These improvements exceeded ( P < 0.05) Placebo, which increased lean body mass by 0.5 ± 0.8%, reduced fat body mass by 9.5 ± 3.6%, and increased back squat one repetition maximum and competition total by 5.7 ± 1.7 and 5.9 ± 1.7%, respectively. Prohormone also experienced multiple adverse effects. These included a 38.7 ± 4.0% reduction in HDL ( P < 0.01), a 32.8 ± 15.05% elevation in LDL ( P < 0.01), and elevations of 120.0 ± 22.6 and 77.4 ± 12.0% in LDL-to-HDL and cholesterol-to-HDL ratios, respectively (both P < 0.01). Prohormone also exhibited elevations in serum creatinine (19.6 ± 4.3%; P < 0.01) and aspartate transaminase (113.8 ± 61.1%; P = 0.05), as well as reductions in serum albumin (5.1 ± 1.9%; P = 0.04), alkaline phosphatase (16.4 ± 4.7%; P = 0.04), and glomerular filtration rate (18.0 ± 3.3%; P = 0.04). None of these values changed (all P > 0.05) in Placebo. The oral PS 3β-hydroxy-5α-androst-1-en-17-one improves body composition and muscular strength. However, these changes come at a significant cost. Cardiovascular health and liver function are particularly compromised. Given these findings, we feel the harm associated with this particular PS outweighs any potential benefit.
