Special Issue Information

Dear Colleagues,

Resistance training is a cornerstone of physical preparation, with the interaction between nutrition, supplementation strategies, and resistance exercise being pivotal in optimizing muscular adaptations. As such, nutritional supplementation strategies have become the subject of continual scientific inquiry. This Special Issue aims to explore cutting-edge research related to nutritional supplementation strategies aimed at promoting resistance training adaptations. We invite authors to contribute original research, reviews, and unique perspectives addressing current works related to enhancing resistance training outcomes for health and athletic performance via nutritional supplementation strategies.

Key Themes:

Authors are encouraged to explore, but are not limited to, the following themes:

  • Nutritional interventions targeting muscle hypertrophy and strength gains.
  • The impact of various ergogenic aids on resistance training performance.
  • The role of carbohydrates, proteins, and amino acids in supporting resistance training adaptations.
  • Creatine supplementation and its effects on power, endurance, and recovery.
  • Resistance exercise, nutrition supplementation strategies, and molecular responses.
  • Resistance exercise, nutritional supplementation strategies, and female athletes.
  • Role of various nutritional supplementation strategies in optimizing performance, recovery, and adaptation to resistance training.

Previous studies have reported that TT genotype carriers of the adenosine A2a receptor (ADORA2A) gene rs5751876 polymorphism have better ergogenic and anti-inflammatory responses to caffeine intake compared to C allele carriers. The aim of the present study was twofold: (1) to investigate the association of the ADORA2A rs5751876 polymorphism with acute caffeine supplementation on hormonal (growth hormone and testosterone) response to resistance exercise (RE); (2) to examine the relationship between the rs5751876 polymorphism and the resting levels of growth hormone and testosterone in athletes who are light caffeine consumers. A double-blind, crossover, placebo-controlled study involving 30 resistance-trained men (age 21.7 ± 4.1) was conducted to assess the impact of caffeine supplementation on serum growth hormone (GH) and testosterone (TS) levels before, immediately after, and 15 min post-RE. One hour before engaging in resistance exercise, subjects were randomly administered 6 mg of caffeine per kg of body mass or a placebo (maltodextrin). After a 7-day washout period, the same protocol was repeated. Resting testosterone and growth hormone levels were examined in the sera of 94 elite athletes (31 females, age 21.4 ± 2.8; 63 males, age 22.9 ± 3.8). Caffeine consumption led to significantly greater increases in GH and TS in men with the TT genotype compared to C allele carriers. Furthermore, in the group of athletes, carriers of the TT genotype had significantly higher testosterone (p = 0.0125) and growth hormone (p = 0.0365) levels compared to C allele carriers. In conclusion, the ADORA2A gene rs5751876 polymorphism may modify the effect of caffeine intake on the hormonal response to exercise. Full article

It is a common belief amongst strength and power athletes that nutritional supplementation strategies aid recovery by shifting the anabolic/catabolic profile toward anabolism. Factors such as nutrient quantity, nutrient quality, and nutrient timing significantly impact upon the effectiveness of nutritional strategies in optimizing the acute responses to resistance exercise and the adaptive response to resistance training (i.e., muscle growth and strength expression). Specifically, the aim of this review is to address carbohydrates (CHOs), protein (PRO), and/or amino acids (AAs) supplementation strategies, as there is growing evidence suggesting a link between nutrient signaling and the initiation of protein synthesis, muscle glycogen resynthesis, and the attenuation of myofibrillar protein degradation following resistance exercise. Collectively, the current scientific literature indicates that nutritional supplementation strategies utilizing CHO, PRO, and/or AA represents an important approach aimed at enhancing muscular responses for strength and power athletes, primarily increased muscular hypertrophy and enhanced strength expression. There appears to be a critical interaction between resistance exercise and nutrient–cell signaling associated with the principle of nutrient timing (i.e., pre-exercise, during, and post-exercise). Recommendations for nutritional supplementation strategies to promote muscular responses for strength and athletes are provided. Full article
