“…After performing these tests, participants met the study dietitian for an introductory consultation to discuss food preferences as well as target protein and energy intakes prior to the initiation of training programs. To assess sleep quality and health status, the Pittsburgh Sleep Quality Index (PSQI) and the General Health Questionnaire-28 (GHQ-28) were used, respectively [ 33 ]. All mentioned procedures were performed in exactly the order for all time measurements.…”

Purpose It is unclear whether resistance (RT) and concurrent training (CT; resistance plus endurance training) combined with different protein intakes have differential effects on muscle hypertrophy, strength, and performance. Therefore, we compared the effects of two high-protein diets (1.6 or 3.2 g.kg −1. d −1 ) during 16 weeks of either CT or RT alone in resistance-trained males. Methods Forty-eight resistance-trained males (age: 26 ± 6 yr, body mass index: 25.6 ± 2.9 kg.m −2 ) performed 16 weeks (four sessions·w −1 ) of CT or RT with either 1.6 g.kg −1. d −1 protein (CT1; n = 12; RT1; n = 12) or 3.2 g.kg −1. d −1 protein (CT2; n = 12; RT2; n = 12). Training adaptations were assessed pre-, mid-, and post-intervention. Results All measures of performance (endurance, vertical jump, and pull-up), lean mass, muscle strength, and power significantly increased post-intervention in all groups, but peak power gains were greater in RT2 compared with RT1 and CT1 ( p < .05). VO 2max significantly increased in both CT groups ( p < .001). Select biochemical markers of kidney and liver function significantly increased within the RT2 and CT2 groups ( p < .05), however, no between-group differences were apparent ( p > .05). Conclusions With the exception of peak power, intake of 1.6 g.kg −1. d −1 of protein appears sufficient to maximize gains in lean mass, muscle strength, performance, and aerobic capacity during both RT and CT without influencing markers of kidney and liver function, indicating this daily protein amount is effective and safely tolerated in young, healthy adults.

Background To date, no studies have compared the efficacy of auto-regulated periodized and linear resistance exercises on anabolic myokines and muscular performance among recreationally active individuals. This study aimed to compare the effects of an 8-week auto-regulated periodized resistance exercise(APRE) program with a linear resistance exercise(LRE) program on insulin-like growth factor-1(IGF-1), follistatin(FST), myostatin(MST), body composition, muscular strength, and power in recreationally active males. Methods Thirty males were randomly assigned to either the APRE group(n = 15) or the LRE group(n = 15). Participants completed training three times a week for eight weeks. The outcome measures included serum IGF-1, FST, MST, muscular strength(isometric knee extension, handgrip), power(vertical jump), lean body mass, and fat mass. Results IGF-1 circulating levels increased over time following APRE(34%), with no significant change following LRE(~-1%). There were no significant differences over time or between groups for FST or MST. Muscular strength(knee extension [21.5% vs. ~16%] and handgrip [right: 31% vs. 25%; left: 31.7% vs. 28.8%]) and power(~ 33% vs. ~26%) significantly increased to a greater extent following APRE compared to LRE. Interestingly, results revealed that lean body mass increased over time only after APRE(~ 3%), but not LRE. Conclusion These findings suggest that APRE may be more effective than LRE in increasing muscular strength, power, and lean body mass, as well as circulating IGF-1 levels, in recreationally active males. The observed differences may be attributed to the increased training volume associated with APRE. However, further research is needed to directly assess muscle protein synthesis.
