Growth factors can be isolated from bovine milk to form a whey growth factor extract (WGFE). This study examined whether WGFE promoted activation of the AKT/mTOR pathway enabling increased lean tissue mass and strength in resistance trained men. Forty six men with >6 months of resistance training (RT) experience performed 12 weeks of RT. Participants consumed 20 g/day of whey protein and were randomised to receive either 1.6 g WGFE/day (WGFE; n = 22) or 1.6 g cellulose/day (control, CONT; n = 24). The primary outcome was leg press one-repetition maximum (LP1-RM) which was assessed at baseline, 6 and 12 weeks...

BACKGROUND: Breast milk is a God-given gift that conveys a mother's love and compassion and that is made according to the needs and age of the child. Mothers who are interested in the welfare of their newborns tend to breastfeed their children. Training programs have been shown to improve breastfeeding self-efficacy in terms of both duration and amount. PURPOSE: The aim of this study was to evaluate the effect of using the progressive muscle relaxation (PMR) technique on the self-efficacy of breastfeeding in mothers with preterm infants...

Resistance training (RT) and high-quality protein ingestion improves muscle mass (MM) and strength (MS). However, no study has evaluated the effect of ingesting milk plus soy protein (SOY) on MM and MS in postmenopausal women (PW). Thus, the aim of this study was to evaluate the effects of adding SOY to milk on MM and MS after 16 weeks of RT. Thirty-two PW were randomized and allocated into two groups: placebo and RT (PL+RT, n = 16) and SOY and RT (SOY+RT, n = 16). The SOY+RT received 25 g of SOY while the PL+RT received 25 g of maltodextrin (placebo)...

BACKGROUND: Resistance training is a potent stimulus to induce muscle hypertrophy. Supplemental protein intake is known to enhance gains in muscle mass through activation of the mammalian target of rapamycin complex 1 (mTORC1) pathway, which initiates protein translation. While the optimal dose of high quality protein to promote post exercise anabolism in young or older men has been investigated, little is known about the minimum doses of protein required to potentiate the resistance exercise activation of anabolic signalling in middle aged men...

In Egypt, rising maternal overweight and obesity is consistent with the transition to westernized diets and a growing reliance on energy-dense, low nutrient foods. Although the first 1,000 days of life are the focus of many programmes designed to prevent many forms of malnutrition, little attention has been paid to maternal dietary practices and weight gain during pregnancy. This study used in-depth interviews with pregnant women (N = 40), lactating women (N = 40), and nonlactating women (N = 40) to gain an understanding of behaviours, perceptions, and cultural beliefs in relation to maternal dietary intake during pregnancy, lactation, and nonlactation; weight gain during pregnancy; birth spacing; and family planning...

Attenuating TNFα/TNFr1 signaling in monocytes has been proposed as a means of mitigating inflammation. The purpose of this study was to examine the effects of a milk protein supplement on TNFα and monocyte TNFr1 expression. Ten resistance-trained men (24.7 ± 3.4 years; 90.1 ± 11.3 kg; 176.0 ± 4.9 cm) ingested supplement (SUPP) or placebo (PL) immediately post-exercise in a randomized, cross-over design. Blood samples were obtained at baseline (BL), immediately (IP), 30-min (30P), 1-h (1H), 2-h (2H), and 5-h (5H) post-exercise to assess plasma concentrations of myoglobin; tumor necrosis factor-alpha (TNFα); and expression of tumor necrosis factor receptor 1 (TNFr1) on classical, intermediate, and non-classical monocytes...

Partial correlation and regression analyses were used in this study. We showed that there is a linear relationship between bone mineral density and serum uric acid within the normal physiologic range, and higher serum uric acid levels had a protective effect on bone loss in postmenopausal osteoporosis. PURPOSE: The significance of the relationship between lumbar bone mineral density (()BMD) and serum uric acid (SUA) levels is unclear. The aims of this study were to investigate on a population-level the association between lumbar BMD and SUA within the normal physiologic range and to determine whether SUA plays a protective role in bone loss in healthy postmenopausal Chinese women...

Previous research suggests that chocolate milk may be a beneficial recovery beverage, yet little is known about how athletes and students training for careers in sports science or health-related fields interpret recommended recovery beverage serving sizes. This study examined college students' ability to correctly apply serving size recommendations for chocolate milk and protein powder used during post-exercise recovery and assessed usual consumption of milk as a recovery beverage. College students (34 women, 39 men) poured the amount of chocolate milk they would consume within 90 minutes after exercise unaided and with the use of a serving size guide...

While effects of the two classes of proteins found in milk (i.e. soluble proteins, including whey, and casein) on muscle protein synthesis have been well investigated after a single bout of resistance exercise (RE), the combined effects of these two proteins on the muscle responses to resistance training (RT) have not yet been investigated. Therefore, the aim of this study was to examine the effects of protein supplementation varying by the ratio between milk soluble proteins (fast-digested protein) and casein (slow-digested protein) on the muscle to a 9-week RT program...

OBJECTIVE: Protein supplementation increases gains in lean body mass following prolonged resistance-type exercise training in frail older adults. We assessed whether the greater increase in lean body mass can be attributed to muscle fiber type specific hypertrophy with concomitant changes in satellite cell (SC) content. DESIGN: A total of 34 frail elderly individuals (77 ± 1 years, n = 12 male adults) participated in this randomized, double-blind, placebo-controlled trial with 2 arms in parallel...

Background: Several physiologically beneficial effects of consuming a whey protein hydrolysate (WPH) have been attributed to the greater availability of bioactive peptides. Aims: The aim was to investigate the effect of four branched-chain amino acid- (BCAA-)containing dipeptides, present in WPH, on immune modulation, stimulation of HSP expression, muscle protein synthesis, glycogen content, satiety signals and the impact of these peptides on the plasma free amino acid profiles. Methods: The animals were divided in groups: control (rest, without gavage), vehicle (water), L-isoleucyl-L-leucine (lle-Leu), L-leucyl-L-isoleucine (Leu-lle), L-valyl-Lleucine (Val-Leu), L-leucyl-L-valine (Leu-Val) and WPH...

Osteopenia is a condition in which bone mineral density (BMD) is lower than normal. Exercise increases BMD in both the young and adults. This study aimed to compare the radial apparent BMD (aBMD) in Japanese females who are Kendo practitioners (KPs) and those with no regular exercise habits (no-REH). The analysis participants consisted of 45 KPs (mean age: 49.4 years old) and 110 no-REH (mean age: 48.8 years old). Radial aBMD was measured using an ultrasonic bone densitometry system. Radial aBMD in KPs was 196...

BACKGROUND: High-intensity exercise induces many metabolic responses. In is unknown whether the response in the peripheral blood mononuclear cells (PBMCs) reflects the response in skeletal muscle and whether mRNA expression after exercise can be modulated by nutritional intake. The aims were to (i) investigate the effect of dairy proteins on acute responses to exercise in skeletal muscle and PBMCs measuring gene expression and (ii) compare this response in young and older subjects. METHODS: We performed two separate studies in young (20-40 years) and older subjects (≥70 years)...

Hyperaminoacidemia following ingestion of cows-milk may stimulate muscle anabolism and attenuate exercise-induced muscle damage (EIMD). However, as dairy-intolerant athletes do not obtain the reported benefits from milk-based products, A2 milk may offer a suitable alternative as it lacks the A1-protein. This study aimed to determine the effect of A2 milk on recovery from a sports-specific muscle damage model. Twenty-one male team sport players were allocated to three independent groups: A2 milk (n = 7), regular milk (n = 7), and placebo (PLA) (n = 7)...

INTRODUCTION: Spontaneous ruptures of extension pollicis longus tendon predominantly occur after undisplaced or minimally displaced distal radial fracture near Lister tubercle. Systemic inflammatory diseases and systemic or local steroid, mechanical causes like bony ridges, presence of bone plate or external fixator pin may precipitate this. Repetitive uses in certain occupation like cooking, cow milking, tailoring and direct trauma in kick boxer are also identified as cause. In this study it is caused by screw tip that also after 20 years...
