Certain particle compounds may directly generate ROS in vivo because of their surface chemistry (eg, metals, organic compounds, and semiquinones) or after bioactivation by cytochrome P450 systems (eg, polycyclic aromatic hydrocarbon conversion to quinones).6, 290 a, 290 b A particle surface or anions present on otherwise more inert particles may disrupt iron homeostasis in the lung and thereby also generate ROS via Fenton reactions.291 Other PM constituents may do so indirectly by the upregulation of endogenous cellular sources (eg, nicotinamide adenine dinucleotide phosphate [NADPH]-RRB- oxidase) 292,293 or by perturbing organelle function (eg, mitochondria) by taken - up PM components.261 Particle stimulation of irritant and afferent ANS fibers may also play a role in local and systemic oxidative stress formation.294 Given the rich antioxidant defenses in the lung fluid, secondarily generated oxidization products of endogenous molecules (eg, oxidized phospholipids, proteins) or a reduction in endogenous antioxidants per se may be responsible at least in part for the state of oxidative stress in the lungs (along with instigating the subsequent cellular responses) rather than ROS derived directly from PM and its constituents.

Stress resistance has not been assessed however and so the biological relevance of this finding is currently unknown.32 Several IER trials (75 - 85 % ER on restricted days) in overweight / obese populations have reported reductions in various markers of oxidative stress 37, 41, which in one study was accompanied by a complementary increase in the anti-oxidant uric acid.37 In a direct comparison of IER (75 % ER for two days / week) and CER, both ER strategies displayed equal efficacy in reducing levels of fast - acting advanced oxidation protein products (AOPP) after six months, which displayed a tendency to occur earlier (i.e. at three months) in the IER group.41 Levels of slow - acting (i.e. long term) AOPP tended to decrease in the IER group and increase in the CER group which the authors proposed may have resulted from IER - induced activation of autophagy, a key homeostatic cellular process in which dysfunctional or unnecessary cellular proteins are degraded and recycled.41 On the other hand, a follow - up study using similar IER / CER protocols demonstrated comparable reductions in AOPP in both groups after three months.48 Summary and Future Research DireStress resistance has not been assessed however and so the biological relevance of this finding is currently unknown.32 Several IER trials (75 - 85 % ER on restricted days) in overweight / obese populations have reported reductions in various markers of oxidative stress 37, 41, which in one study was accompanied by a complementary increase in the anti-oxidant uric acid.37 In a direct comparison of IER (75 % ER for two days / week) and CER, both ER strategies displayed equal efficacy in reducing levels of fast - acting advanced oxidation protein products (AOPP) after six months, which displayed a tendency to occur earlier (i.e. at three months) in the IER group.41 Levels of slow - acting (i.e. long term) AOPP tended to decrease in the IER group and increase in the CER group which the authors proposed may have resulted from IER - induced activation of autophagy, a key homeostatic cellular process in which dysfunctional or unnecessary cellular proteins are degraded and recycled.41 On the other hand, a follow - up study using similar IER / CER protocols demonstrated comparable reductions in AOPP in both groups after three months.48 Summary and Future Research Direstress 37, 41, which in one study was accompanied by a complementary increase in the anti-oxidant uric acid.37 In a direct comparison of IER (75 % ER for two days / week) and CER, both ER strategies displayed equal efficacy in reducing levels of fast - acting advanced oxidation protein products (AOPP) after six months, which displayed a tendency to occur earlier (i.e. at three months) in the IER group.41 Levels of slow - acting (i.e. long term) AOPP tended to decrease in the IER group and increase in the CER group which the authors proposed may have resulted from IER - induced activation of autophagy, a key homeostatic cellular process in which dysfunctional or unnecessary cellular proteins are degraded and recycled.41 On the other hand, a follow - up study using similar IER / CER protocols demonstrated comparable reductions in AOPP in both groups after three months.48 Summary and Future Research Directions

Immediately before or after a bout of physical exercise, consumption of 10 - 30 grams of cysteine - rich whey protein (depending on body weight and exercise intensity) is a better option since this delivers amino acids preferentially to skeletal muscle while also providing cysteine to lessen oxidative stress.15

Soreness after a workout is caused by a combination of inflammation, muscle damage and oxidative stress — and researchers suggest the natural compounds in Montmorency tart cherries, including anthocyanins, may aid in faster recovery, decreased muscle pain, and less muscle damage when consumed prior to working out, as well as after.1, 2,3
