Change in Serum Biomarkers in Patients with Osteoarthritis treated with Collagen Hydrolysate: Results of a Prospective Randomized Study
Collagen hydrolysate is a nutritional supplement that is used for the treatment of patients with osteoarthritis. Collagen hydrolysate –
chemically speaking – is a mixture of proteins, namely collagen peptides, that are manufactured on the basis of skin and bones from
cattle, pigs or fish on an industrial scale. Prospective, randomized, placebo-controlled trials demonstrated that the oral ingestion of 10
grams of collagen hydrolysate per day for the ...

Beneficial Effects of Collagen Hydrolysate: A Review on Recent Developments
Abstract Collagen hydrolysate (CH) has received increasing attention in recent decades. This review mainly summarizes the recent developments (year 2010-2017) regarding the beneficial effects of CH in animal experiments and clinical trials. These beneficial effects include antioxidant, anti aging, anti osteoporotic and anti osteoarthritis, anti-inflammatory, anti tumor, wound healing, anti hypertensive and anti atherosclerotic, anti obesity and hypoglycemic effects. We also make comments on the current researches ...

Amelioration of estrogen deficiency-induced obesity by collagen hydrolysate
Abstract
Objectives: Menopausal transition with declining estrogen levels significantly affects the physiological properties of women and consequently contributes to a series of medical conditions, including obesity. Obesity is a crucial risk factor associated with cardiovascular diseases, diabetes mellitus, and breast cancer. Increasing dietary protein content improves satiety and energy expenditure. Thus, we hypothesize that supplementing with collagen, a common dietary protein, may alleviate menopause-induced ...

Vegan diets: practical advice for athletes and exercisers
Abstract: With the growth of social media as a platform to share information, veganism is becoming more visible, and could be becoming more accepted in sports and in the health and fitness industry. However, to date, there appears to be a lack of literature that discusses how to manage vegan diets for athletic purposes. This article attempted to review literature in order to provide recommendations for how to construct a vegan diet for athletes and exercisers. While little data could be found in the sports nutrition literature ...

The short-term effect of high versus moderate protein intake on recovery after strength training in resistance-trained individuals
Abstract
Background: Dietary protein intakes up to 2.9 g.kg−1 .d−1 and protein consumption before and after resistance training may enhance recovery, resulting in hypertrophy and strength gains. However, it remains unclear whether protein quantity or nutrient timing is central to positive adaptations. This study investigated the effect of total dietary protein content, whilst controlling for protein timing, on recovery in resistance trainees. Methods: ...

The influence of D-ribose ingestion and fitness level on performance and recovery
Abstract
Background: Skeletal muscle adenosine triphosphate (ATP) levels are severely depleted during and following prolonged
high intensity exercise. Recovery from these lower ATP levels can take days, which can affect performance on subsequent
days of exercise. Untrained individuals often suffer the stress and consequences of acute, repeated bouts of exercise by
not having the ability to perform or recovery sufficiently to exercise on subsequent days. Conversely, trained individuals
may be able to ...

The impact of sleeping with reduced glycogen stores on immunity and sleep in triathletes
Abstract
Purpose We investigated the effects of a 3-week dietary periodization on immunity and sleep in triathletes. Methods 21 triathletes were divided into two groups with different nutritional guidelines during a 3-week endurance training program including nine twice a day sessions with lowered (SL group) or maintained (CON group) glycogen availability during the overnight recovery period. In addition to performance tests, sleep was monitored every night. Systemic and mucosal immune parameters as ...

Repeated High Intensity Bouts with Long Recovery: Are Bicarbonate or Carbohydrate Supplements an Option?
The effects of varying recovery modes and the influence of preexercise sodium bicarbonate and carbohydrate ingestion on repeated
high intensity performance, acid-base response, and recovery were analyzed in 12 well-trained males.They completed three repeated
high intensity running bouts to exhaustion with intervening recovery periods of 25 min under the following conditions: sodium
bicarbonate, active recovery (BIC); carbohydrate ingestion, active recovery (CHO); placebo ingestion, ...
