The effects of novel anti-inflammatory nutritional and pharmaceutical supplementation during resistance training on muscle and bone in older adults

2015 December 1900 (has links)
Introduction: Chronic inflammation with aging is associated with sarcopenia and osteoporosis. Bovine colostrum is the first milk secreted by cows following parturition and contains bioactive substances, while ibuprofen is a non-steroidal anti-inflammatory drug. Both target the inflammatory pathway regulated by cyclooxygenase and have potential to increase muscle and bone mass when combined with resistance training. Objectives: To determine efficacy of novel anti-inflammatory nutritional (bovine colostrum) and pharmaceutical (ibuprofen) supplementation during resistance training on muscle and bone properties and strength in older adults. Methods: Older adults (≥50y) were randomly assigned to receive 38g/d of colostrum or whey protein during a resistance training program for 8 weeks; postmenopausal women (≥60y) were randomly assigned to receive ibuprofen (400 mg) or placebo post-exercise while performing a resistance training program or stretching program (3d/wk) for 9 months. Both studies utilized dual energy x-ray absorptiometry (DXA) for body composition and predicted 1-repetition maximum for strength. The bovine colostrum study further assessed muscle thickness of the biceps and quadriceps, plasma insulin-like growth factor-1, and inflammation and bone resorption markers; the ibuprofen study further assessed bone and muscle properties and estimates of bone strength (peripheral quantitative computed tomography), and dynamic balance. Results: Bovine colostrum supplementation during resistance training increased leg press strength (21%) and reduced bone resorption (-29%) versus whey protein. Both colostrum and whey protein groups improved chest press strength, muscle thickness, and lean tissue mass. Ibuprofen alone appeared beneficial for preventing loss of areal bone density at Ward’s region (3%) and bone properties at the distal radius (0.5%) and radial shaft (1.1%), while exercise alone appeared beneficial for bone properties at the distal radius (0.6%). However, the interaction of resistance training and ibuprofen negated the benefits at the distal radius (-1.5%). Neither ibuprofen nor resistance training was effective for increasing lean tissue mass, although resistance training improved body fat percentage (-2.0%), increased upper and lower body strength (23%, 110%), and preserved muscle density of the calf (-3.1%). Conclusion: While bovine colostrum could be taken within close proximity to exercise, ibuprofen should not be as it may interfere with the effects of exercise when the two interventions are combined.

Effect of colostrum supplementation on baby pig performance

Scotten, Spencer Shannon January 1900 (has links)
Master of Science / Department of Animal Sciences and Industry / Jim L. Nelssen / Two experiments evaluated the effect of colostrum and energy supplementation on the performance and immune response of baby piglets. In Exp. 1, 301 newborn pigs (Line 600 × 241; DNA, 1.48 kg) were used in a 21-d study. Pigs were weighed and allotted to one of three treatments at 6-h of age in a randomized complete block design with 23 replications (litters) per treatment. Piglets were blocked by weight and randomly assigned a treatment. Runt piglets (birthweight < 0.8 kg) were tested in experiment 1 and 2. Dietary treatments were a control with no dietary supplementation, an energy supplement (1.5 ml containing glucose, dried milk, medium chain triglycerides, and tea extract), and bovine colostrum (30 ml). The supplements were given as an oral gavage. A single treatment was administered at 6-h after birth. At 30-h of age approximately 1ml of blood was obtained for an immunocrit assay of serum. The glucose based energy supplement (milk protein, medium chain triglycerides) had no (P > 0.05) effect on weight or ADG at any of the weigh periods (30-h, d 5, d 7, d 14, and weaning), immunocrit ratio, or survival rate. The bovine colostrum treatment had a negative (P < 0.05) effect on weight at 24-h, d 5, and d 7, immunocrit ratio, and survival rate. There was no (P > 0.05) effect of treatment on weight at weaning. . In Exp. 2, 364 newborn pigs (Line 600 × 241; DNA, 1.48 kg) were used in a 21-d study. Pigs were weighed and allotted to one of three treatments in a randomized complete block design with 25 replications (litters) per treatment. Dietary treatments were a control with no dietary supplementation, an energy supplement (1.5 ml, glucose based, containing milk protein, medium chain triglycerides, and tea extract), and bovine colostrum (10 ml). The supplements were given as an oral gavage. A single treatment was administered at 6-h after birth. At 30-h of age blood was collected for analysis of serum immunocrit. Body weights, ADG during the duration of the trial, immunocrit ratio, and survival rates were similar (P > 0.05) for the treatment groups. In both experiment 1 and 2 there were no treatment by weight group interaction. In summary, under the conditions of these experiments supplementation of 30 ml of bovine colostrum had a negative effect (P < 0.05) on immunocrit ratio and survival rate (P > 0.05), of the treatments affected on weaning weights when compared to the control.
