“…A neutrofilia apresentada segue um padrão de resposta aguda de neutrófilos que em geral apresenta um aumento acima do valor basal imediatamente após o exercício, sustentada por até 120 min 18 , decorrente da desmarginação dos neutrófilos provocada por alterações hemodinâmicas, como a elevação do débito cardía-co, associada à ação de catecolaminas e dos níveis de cortisol 17,19 . A monocitose transitória apresentadas pode estar relacionada com a ativação dos macrófagos no mecanismo de resposta inflamatória 20 .…”

RESUMO Introdução: A performance no futebol depende de vários fatores, entre eles, conhecimento das alterações fisiológicas ocorridas durante o jogo. Objetivo: Identificar as alterações hematológicas, imunológicas, enzimáticas, hormonais e inflamatórias decorrentes do aumento de suas concentrações plasmáticas após um jogo de futebol. Métodos: A amostra foi constituída por 42 atletas do sexo masculino, com média de idade de 25,7 ± 4,6 anos, todos profissionais da modalidade futebol. Todos os atletas participaram de, no mínimo, 90 minutos de um jogo oficial. Foram realizadas análise sanguíneas 2 horas antes do jogo, após o jogo, e ainda, em 24, 48 e 72 horas. Foram analisadas as alterações nos biomarcadores hematológicos, imunológicos, enzimáticos (creatina quinase total - CKt, lactato desidrogenase - LDH, aspartato aminotransferase - AST), cortisol, testosterona e proteína C-reativa (PCR). Resultados: Foram verificadas alterações dos níveis de eritrócitos, Hb e Hct, no entanto, clinicamente irrelevantes e sem significado fisiológico. O número de leucócitos, neutrófilos, monócitos, eosinófilos e linfócitos apresentaram alterações significativas (p < 0,05). Foram verificados picos de elevação após os jogos para a LDH e PCR e depois de 24 horas para a CKt e AST (p < 0,05). As concentrações de cortisol aumentaram de forma significativa após os jogos enquanto os níveis de testosterona diminuíram; no período de 24 horas os padrões se reverteram (p < 0,05). Conclusão: O jogo de futebol não altera de forma aguda os parâmetros hematológicos. A função imunológica apresenta leucocitose acentuada com expressão simultânea de neutrofilia e linfopenia. O jogo de futebol é suficientemente agressivo para induzir danos musculares, gera um estado catabólico, e ainda, aumenta as reações inflamatórias.

“…Leucine-derived metabolite β-hydroxy-β-methylbutyrate ingestion has proved beneficial in recovery from the soreness. Resistance exercise (weight-lifting) elevates oxidation products in plasma, perturbs leukocyte redistribution and leukocyte functionality (Freidenreich and Volek 2012). Whey protein isolate nanoparticles were prepared using ethanol desolvation and their capacity to incorporate ZnCl 2 was analysed.…”

The looming food insecurity demands the utilization of nutrient-rich residues from food industries as valueadded products. Whey, a dairy industry waste has been characterized to be excellent nourishment with an array of bioactive components. Whey protein comprises 20 % of total milk protein and it is rich in branched and essential amino acids, functional peptides, antioxidants and immunoglobulins. It confers benefits against a wide range of metabolic diseases such as cardiovascular complications, hypertension, obesity, diabetes, cancer and phenylketonuria. The protein has been validated to boost recovery from resistance exercise-injuries, stimulate gut physiology and protect skin against detrimental radiations. Apart from health invigoration, whey protein has proved its suitability as fat replacer and emulsifier. Further, its edible and antimicrobial packaging potential renders its highly desirable in food as well as pharmaceutical sectors. Considering the enormous nutraceutical worth of whey protein, this review emphasizes on its established and emerging biological roles. Present and future scopes in food processing and dietary supplement formulation are discussed. Associated hurdles are identified and how technical advancement might augment its applications are explored. This review is expected to provide valuable insight on whey protein-fortified functional foods, associated technical hurdles and scopes of improvement.

“…Differences in the effects of whey and soy protein supplementation on sex hormone responses to acute resistance exercise are further highlighted by our observations on cortisol. The SPI and CHO groups demonstrated similar and characteristic responses to resistance exercise at each time point [41]. This indicates that the observed differences between whey and soy groups can be attributed to features of whey protein that provided a positive blunting effect on the cortisol response.…”

Our main findings demonstrate that 14 days of supplementation with soy protein does appear to partially blunt serum testosterone. In addition, whey influences the response of cortisol following an acute bout of resistance exercise by blunting its increase during recovery. Protein supplementation alters the physiological responses to a commonly used exercise modality with some differences due to the type of protein utilized.
