Special Issue Information

Dear Colleagues,

This Special Issue covers a wide range of topics that will help us to better understand the effects of diet and supplementation on health and how they improve exercise performance.

In recent years, not only scientists but also training staff, athletes, and active adults have paid more attention to diet and appropriate supplementation. It has been observed that a well-composed diet and appropriately selected supplementation may directly affect the level of fitness, body composition, and health. The model of a well-composed mixed diet or high-carbohydrate diet that has been used for years is currently being replaced by other diets such as ketogenic or vegetarian. In turn, apart from the most frequently chosen supplements, such as creatine and caffeine, omega 3 acids, vitamin D3, and probiotics are seen as equally effective.

I would like to invite all researchers to submit papers relating to the abovementioned issues, with particular emphasis on innovative research in which the impact of innovative diets and pro-health supplements on improving performance and health parameters have been studied.

Dr. Małgorzata Michalczyk

We examined whether post-exercise yogurt intake reduced cardiovascular strain during outdoor interval walking training (IWT) in older people during midsummer. The IWT is a training regimen repeating slow and fast walking at ~40% and ≥70% peak aerobic capacity, respectively, for 3 min each per set, ≥5 sets per day, and ≥4 days/wk. We randomly divided 28 male and 75 female older people (~73 yr), who had performed IWT ≥12 months, into a carbohydrate group (CHO-G) consuming jelly (45 g CHO, 180 kcal) and a yogurt group (YGT-G) consuming a yogurt drink (9.3 g protein, 39 g CHO, 192 kcal) immediately after daily IWT for 56 days while monitoring exercise intensity and heart rate (HR) with portable devices. We analyzed the results in 39 subjects for the CHO-G and 37 subjects for the YGT-G who performed IWT ≥ 4 days/wk, ≥60 min total fast walking/wk, and ≥4 sets of each walk/day. We found that the mean HR for fast walking decreased significantly from the baseline after the 30th day in the YGT-G (p < 0.03), but not in the CHO-G (p = 1.00). There were no significant differences in training achievements between the groups. Thus, post-exercise yogurt intake might reduce cardiovascular strain during outdoor walking training in older people. Full article
