5133 Background: Androgen deprivation therapy (ADT) is a well-established treatment for hormone sensitive prostate cancer, but is associated with adverse side effects including loss of bone and lean mass and increased adipose mass. Activin receptor type IIB (ActRIIB) signaling is necessary for the negative regulation of lean tissue mass and treatment with a non-signaling, decoy ActRIIB results in a robust increase in lean tissue mass. Methods: Similar to ADT patients, orchiectomized (ORX) mice lose bone and lean mass and gain fat mass. To determine the therapeutic potential of inhibiting ActRIIB signaling to reduce the negative effects associated with ADT, we treated sham-operated (SHAM) and orchiectomized (ORX) mice with RAP-031, a fusion protein comprised of a form of the extracellular domain of ActRIIB linked to a murine Fc. Mice received twice weekly injections for 10 weeks with either vehicle (VEH) or 10 mg/kg RAP-031 (RAP). NMR scanning was used to determine body composition and whole body DEXA scans were performed to determine bone mineral density (BMD). Results: ORX resulted in a 4.4% decrease in BMD, an 18% reduction in lean tissue and a 41.6% increase in adiposity compared to the VEH-SHAM cohort. Both RAP-031treated groups of mice had significantly increased BMD and lean tissue mass and decreased adipose mass compared to their respective VEH groups. However, BMD, lean tissue and adiposity were not significantly different between the VEH-SHAM and RAP-ORX groups. These data illustrate that RAP-031 treatment completely attenuates ORX-induced alterations in bone, lean and fat mass. Conclusions: These data support the hypothesis that treatment with a form of soluble ActRIIB can offset negative side effects of ADT and have significant therapeutic implications for the treatment of patients with prostate cancer.

And Control

Thirty young women comprised three groups (n = 10 in each): whole routine (W) training, split routine training (S), and control. The W group did four upper (five sets, 6-10 RM) and three lower body (five sets, 10-12 RM) weight training exercises together in single sessions twice a week for 20 weeks. The S group did the upper body exercises 2 days a week and the lower body exercises on 2 other days of the week. The single maximal weight lift (1-RM) increased (p < 0.05) (W/S) 54/69%, 33/32%, and 21/22% in arm curl, bench press, and leg press exercises, as did arm (10/9%), and trunk (3.4/2.7%) lean tissue mass, as measured by dual energy x-ray absorptiometry. Leg lean mass increased significantly only in W (4.9% vs. 1.7% in S). Whole-body lean tissue mass increased (4.1/2.6%), and whole body % fat (−1.1/−1.3%) decreased with training. It is concluded that in healthy young women, whole and split weight training routines produce similar results over the first 5 months of training.

Repeated Measures Design

Creatine supplementation in close proximity to resistance training may be an important strategy for increasing muscle mass and strength; however, it is unknown whether creatine supplementation before or after resistance training is more effective for aging adults. Using a double-blind, repeated measures design, older adults (50–71 years) were randomized to 1 of 3 groups: creatine before (CR-B: n = 15; creatine (0.1 g/kg) immediately before resistance training and placebo (0.1 g/kg cornstarch maltodextrin) immediately after resistance training), creatine after (CR-A: n = 12; placebo immediately before resistance training and creatine immediately after resistance training), or placebo (PLA: n = 12; placebo immediately before and immediately after resistance training) for 32 weeks. Prior to and following the study, body composition (lean tissue, fat mass; dual-energy X-ray absorptiometry) and muscle strength (1-repetition maximum leg press and chest press) were assessed. There was an increase over time for lean tissue mass and muscle strength and a decrease in fat mass (p < 0.05). CR-A resulted in greater improvements in lean tissue mass (Δ 3.0 ± 1.9 kg) compared with PLA (Δ 0.5 ± 2.1 kg; p < 0.025). Creatine supplementation, independent of the timing of ingestion, increased muscle strength more than placebo (leg press: CR-B, Δ 36.6 ± 26.6 kg; CR-A, Δ 40.8 ± 38.4 kg; PLA, Δ 5.6 ± 35.1 kg; chest press: CR-B, Δ 15.2 ± 13.0 kg; CR-A, Δ 15.7 ± 12.5 kg; PLA, Δ 1.9 ± 14.7 kg; p < 0.025). Compared with resistance training alone, creatine supplementation improves muscle strength, with greater gains in lean tissue mass resulting from post-exercise creatine supplementation.

Meta Analyses

Creatine supplementation in conjunction with resistance training (RT) augments gains in lean tissue mass and strength in aging adults; however, there is a large amount of heterogeneity between individual studies that may be related to creatine ingestion strategies. Therefore, the purpose of this review was to (1) perform updated meta-analyses comparing creatine vs. placebo (independent of dosage and frequency of ingestion) during a resistance training program on measures of lean tissue mass and strength, (2) perform meta-analyses examining the effects of different creatine dosing strategies (lower: ≤5 g/day and higher: >5 g/day), with and without a creatine-loading phase (≥20 g/day for 5–7 days), and (3) perform meta-analyses determining whether creatine supplementation only on resistance training days influences measures of lean tissue mass and strength. Overall, creatine (independent of dosing strategy) augments lean tissue mass and strength increase from RT vs. placebo. Subanalyses showed that creatine-loading followed by lower-dose creatine (≤5 g/day) increased chest press strength vs. placebo. Higher-dose creatine (>5 g/day), with and without a creatine-loading phase, produced significant gains in leg press strength vs. placebo. However, when studies involving a creatine-loading phase were excluded from the analyses, creatine had no greater effect on chest press or leg press strength vs. placebo. Finally, creatine supplementation only on resistance training days significantly increased measures of lean tissue mass and strength vs. placebo.
