“…Consumption of about 225 mg sumac extract/300 ml sumac juice per day provides significant reduction in the levels of the circulated inflammatory markers of healthy subjects. The data obtained matched with other researchers' results who reported a decrement in serum inflammatory markers including C reactive protein (CRP) by 25% after 28 days (8,14,19,21,23,26). The potential of skeletal troponin I and hyp as markers of muscle injury may be useful for assessing the effects of intense exercise for soft tissue injuries (31,48,51,55).…”

“…Whereas the oxidative tissue damage activates muscle tissues for the inflammatory response and excessive production of oxidative free radicals which increase secondary muscle soreness (19,28). So, nutritional antioxidants of plant origin have been suggested as an alternative treating strategy for ameliorating muscle pain and soreness following exercise or exhausted overtraining (8).…”

The main target of this study was to measure the influence of sumac juice drink on muscle indices and pain during an acute, intense exercise for 30 days. Forty healthy volunteers (15–25 years) were involved in aerobic exercise program for 4 weeks. Participants ingested sumac juice or placebo drink twice daily for 30 days. All participants were subjected for the evaluation of pain and estimation of serum: creatine kinase (CK), lactic acid dehydrogenase (LDH), troponin I, hydroxyproline (hyp), total antioxidant capacity (TAC), and in vitro antioxidant activity of sumac juice using pre-validated visual analog scale, colorimetric and immunoassays. The participants of both groups, placebo and sumac, showed an increment in pain scores both during exercise and post-exercise intervals. However, the sumac juice group showed a significant smaller increase in the pain scores compared to the placebo group. Participants in the sumac juice group were more willing to use the drink in the future. They achieved a higher satisfaction of sumac juice in ameliorating and the reduction of pain. Also, the sumac group showed a significant enhancement in the level of CK, LDH, troponin I, hyp, along with significant increase in serum (TAC) compared to the placebo group. The protective activity of muscle may relate to the antioxidant activity of phenolic component(s) in sumac juice as measured by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging (87.9%) and β-carotene–linoleic acid (68.7%) assays. These data suggest that oral administration of sumac juice may have a beneficial effect on muscle performance among athletes.

“…[La] appears to be a meaningful biomarker of muscle fatigue if workload conditions are standardized [151]. Soccer is a sport consisting of high-intensity intermittent exercise, and [La] correlates with the magnitude of exercise performed immediately before blood sampling [152].…”

“…As a result, increases in [La] in soccer players must be used carefully as a biomarker of fatigue. Another marker to monitor metabolic activity, energy requirement and the onset of muscle fatigue is blood ammonia, which closely follows [La] response [151]. Ammonia increases after a soccer match [153,154] and could have detrimental effects on fatigue-related performance, thus particular attention should be paid to their monitoring [153].…”

Background:Soccer presents physiological, metabolic, physical and psychological demands which can deteriorate players' performance due to fatigue. The high variability in physiological, metabolic, physical and psychological responses also influences the magnitude of exercise-induced muscle damage, with symptoms negatively affecting neuromuscular function during recovery or subsequent training sessions or matches. Consequently, more precise and consistent knowledge is required in this area to optimize training and performance. Objective:Therefore, the purpose is to sum-up current evidence on fatigue and recovery in soccer players, to shed light on factors that can affect players' performance, and to suggest applications for coaches and further research. Method:A comprehensive review of the scientific literature on the field was conducted. Results:Physical performance decrements during matches have traditionally been associated with physiological fatigue, but the magnitude of the symptoms in soccer players is unclear and depends on several factors. Moreover, the decline in physical performance during a soccer match is related to specific demands of each match. These could explain inter-individual variability in acute fatigue or training recovery processes when comparing players from the same team. Recovery counteracts the effects of fatigue, both peripheral and central, but there is a lack of consensus about the usefulness of tests used to monitor fatigue and recovery kinetics. Conclusion:Although fatigue and recovery in soccer has been extensively studied, there are still uncertainties about the underlying mechanisms because they are influenced by physiological and match-related demands.

“…Physical exercise is important for maintaining physical fitness and can contribute positively to maintaining a healthy weight, muscle strength, promoting physiological well-being and strengthening the immune system [1][2][3]. Developing research has demonstrated that many of the benefits of exercise are mediated through the release of myokines which promote the growth of new tissue and reduces the risk of developing inflammatory diseases [4].…”

This study was designed to determine the level of oxidative stress using the level of circulating C-reactive protein, malondialdehyde and absolute lymphocyte counts in pre and post-acute exercise as studies have shown that acute exercise enhances the immunological responses of stressed individuals. Twenty five (25) healthy young male undergraduate students with an average age of 24.3 ± 3 years and body mass index of 22.7 ± 1.8 (kg/m 2 ) participated fully in the study. The levels of malondialdehyde and C-reactive protein were significantly higher at one hour, four hours and twenty-four hour post exercise when compared with the pre-exercise stage whereas the absolute lymphocyte count and absolute neutrophils count were significantly higher at one hour and four hours post exercise when compared with the pre-exercise stage. Absolute lymphocyte count, absolute neutrophils count, Creactive protein and malondialdehyde concentrations are increased in acute exercise which is an indication of an acute phase responses during stressful events.
