The effects of protease supplementation on skeletal muscle function and DOMS following downhill running

Protease supplementation has been shown to attenuate soft tissue injury resulting from intense exercise. The aim of this study was to evaluate the effects of protease supplementation on muscle soreness and contractile performance after downhill running. Ten matched pairs of male participants ran at a -10% grade for 30 min at 80% of their predicted maximal heart rate. The participants consumed two protease tablets (325 mg pancreatic enzymes, 75 mg trypsin, 50 mg papain, 50 mg bromelain, 10 mg amylase, 10 mg lipase, 10 mg lysozyme, 2 mg chymotrypisn) or a placebo four times a day beginning 1 day before exercise and lasting a total of 4 days. The participants were evaluated for perceived muscle soreness of the front and back of the dominant leg, pressure pain threshold by dolorimetry of the anterior medial, anterior lateral, posterior medial and posterior lateral quadrants of the thigh, and knee extension/flexion torque and power. The experimental group demonstrated superior recovery of contractile function and diminished effects of delayed-onset muscle soreness after downhill running when compared with the placebo group. Our results indicate that protease supplementation may attenuate muscle soreness after downhill running. Protease supplementation may also facilitate muscle healing and allow for faster restoration of contractile function after intense exercise.     

Transformation of Patriarchal Regimes, Literacy, and Schooling

Literacy has been among the most publicly contested domains in gender struggles; the way that history of literacy is gendered and interpreted makes a difference to the way reading and writing is thought of today. Broadly understood, gender signals a wide range of concerns with subjectivities, social relations, and historical dynamics. Literacy campaigns can be linked both to attempts to consolidate patriarchalism in early modern Europe and to complex struggles attending its 18th-century demise. In 19th-century England, both bourgeois and oppositional public spheres engendered patterns of solidarity, identity, gender polarization, and exclusion in which contested notions of individual and collective literacy played a key role. Elsewhere, schools were called upon to engender a proletariat or tame its radicalism, teach females how to read or change their reading habits, instruct children in writing or give them to understand that their mother tongue did not count as school knowledge.
