Abstract. In a few last decades oxidative stress detected in a variety of physiological processes where reactive oxygen species (ROS) and reactive nitrogen species (RNS) play a central role. They are directly involved in oxidation of proteins, lipids and nucleic acids. In certain concentrations they are necessary for cell division, proliferation and apoptosis. Contractile muscle tissue at aerobic conditions form high ROS flow that may modulate a variety of cell functions, for example proliferation. However, slight increase in ROS level provide hormetic effect which may participate in adaptation to heavy weight training resulted in hypertrophy and proliferation of skeletal muscle fibers. This review will discuss ROS types, sites of generation, strategies to increase force production and achieve skeletal muscle hypertrophy.

“…To test this hypothesis, we recently examined the effects of feeding on the post-resistance exercise androgen receptor response [61] . We surmised that the decrease in testosterone concentrations following post-exercise feeding would be associated with an increase in androgen receptor content.…”

Skeletal muscle displays an impressive capability to adapt to various stimuli. Exercise and physical activity, in their many forms, present specific stresses to muscle. Depending on the exact nature of the stress, muscle may adapt by increasing size, improving neuromuscular performance, or enhancing endurance capabilities. In this article, we provide an overview of the basics of neuromuscular physiology, principles of exercise training, adaptations to exercise, and the role of the endocrine system and intramuscular signalling pathways for mediating these responses and adaptations.

“…Supplemental protein intake facilitates MPS during resistance training and induces a positive net protein balance [1], this is a positive algebraic event when protein synthesis is greater than protein breakdown [2,3]. During resistance exercise, athletes are generally required to consume more protein for restoration and reformation of damaged muscle [4].…”

“…It has been reported that a high protein intake (1.6-1.8 g/kg/day) improves body composition, enhances lean body mass [5], and affects anabolic hormones that are related to muscle remodelling [6]. Previous studies have reported that resistance exercise stimulates the secretion of anabolic growth hormone and testosterone [4], which stimulates MPS [7]. During resistance exercise, a high protein intake reportedly increases resting testosterone, cortisol, growth hormone, and insulin levels [4].…”

“…Previous studies have reported that resistance exercise stimulates the secretion of anabolic growth hormone and testosterone [4], which stimulates MPS [7]. During resistance exercise, a high protein intake reportedly increases resting testosterone, cortisol, growth hormone, and insulin levels [4]. In contrast, other studies suggested that these hormones were unrelated to the magnitude of the MPS response or total muscle hypertrophy with resistance training [8,9].…”

Objective: Previous studies have presented the effects of carbohydrate and protein intake using a single food or supplement. However, little knowledge is available regarding the long-term effects of protein diet supplementation on muscle mass and function. This study was conducted to investigate the effects of a 12-week high-intensity resistance exercise program combined with a high-carbohydrate (HCHO), high-protein (HPRO) diet on body composition, muscle function, anabolic/catabolic hormones, and blood amino acid levels.Methods: This study included 27 male college students, who were divided into an HPRO group (n=12) and an HCHO group (n=15). Three to five sets of resistance exercises were performed four times a week at 75% of 1-repetition maximum for 12 weeks. Results:The weight and body fat percentage decreased in both groups after the 12-week resistance exercise, and muscle mass increased in the HPRO group. The peak torque increased in the HPRO group, and the average power increased in both the HCHO and HPRO groups, although there was no significant difference between the changes in both groups. However, the testosterone level and the ratio of testosterone to cortisol increased in the HCHO group, and the changes were significantly different between the groups. The blood essential amino acid (EAA) and non-essential amino acid levels showed a time × group effect. Conclusion: Protein supplementation of a high-carbohydrate diet during resistance training may enhance body composition and muscle mass and function by increasing the blood EAA levels. Therefore, considering that Asians tend to consume high-carbohydrate diets, a diet with slightly less carbohydrate and increased protein may be more effective for increased muscle strength and mass during training.
