“Background Reactive oxygen species (ROS) have been implicated as one of the causes of skeletal muscle fatigue during both aerobic and anaerobic exercise . Although small increases in exercise induced ROS are important for stimulating cellular growth and maximising muscular force production [2, 3], excessive accumulation leads to a pro-oxidant environment which Pevonedistat nmr Nabilone can damage DNA, lipid and INCB018424 concentration protein membranes [4, 5]. Cellular damage may also impair cross-bridge cycling during skeletal muscle contraction and accelerate
the onset of fatigue [2, 6, 7]. This is supported by previous work suggesting that a bout of resistance training induces an excessive increase in ROS production which could be implicated in the reduction in skeletal muscle force generating capacity observed during exercise [4, 8, 9]. To maximise gains in muscular hypertrophy an RT session would typically involve exercising at a moderate intensity, defined as lifting a load between 65-85% of an individual’s one repetition maximum (RM), and using a high volume, typically 3–6 sets of 6–15 repetitions of the exercise . Goldfarb and colleagues  found significant increases in the plasma ROS markers malondialdehyde (MDH) and protein carbonyls (PC) following arm flexor exercise involving four sets of a 12 repetition maximum (RM) load. Similar results have also been found for lower body resistance exercise where plasma measures of oxidised gluthanione (GSSG) and protein oxidation were elevated following 30 min of sub-maximal squatting exercise . The primary cause of RT induced oxidative damage appears to result from increased xanthine and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase production, together with ischemia–reperfusion which results in an increase in xanthine oxidase (XO) and peroxynitrite [9, 11, 12].
