Nanobubbles Water Curcumin Extract Reduces Injury Risks on Drop Jumps in Women: A Pilot Study

Abstract

Purpose. To verify the beneficial effects of Nanobubbles water curcumin extract (NCE) supplementation on health promotion and to demonstrate the application of NCE in reducing the risk of musculoskeletal injury. Methods. In the current study, 12 females were randomly assigned to NCE (15g/day) and maltodextrin groups. Performance and related body composition were evaluated at 2 time points—presupplementation (pre-) and after 4 weeks of postsupplementation (post-). The posttest consists of a set of biochemical parameters for antifatigue activity and injury status evaluation. Results. NCE group exhibited significantly lower levels of alanine aminotransferase (ALT), alkaline phosphatase (ALP), triglycerides (TG), and higher high-density lipoprotein (HDL) after a 4-week supplementation, compared with the placebo group. After a 15-minute session on the spinning bike, serum lactate and ammonia levels were decreased and glucose was economized in the NEC group. 4-week-NCE supplementation was also able to reduce the peak vertical ground reaction force (PVGRF) during drop jump. Therefore, the risk of musculoskeletal system in lower extremity could be reduced. Conclusion. We demonstrate that 4-week-NCE supplementation can also be used in explosiveness exercise for better physiological adaptation. Thus, NCE has potential for use with nutrient supplements toward a variety of benefits for athletics.

Influence of the Menstrual Cycle on Blood Markers of Muscle Damage and Inflammation Following Eccentric Exercise

“…Thus, the higher ALT concentration in the LFP would agree with some results that suggest the lack of estrogen's protective effect, but further investigation is warranted. On the contrary, the AST response was not affected by menstrual cycle phases but increased in post-exercise measurements, which is in accordance with previous female studies [43,44].…”

Effects of Curcumin Supplementation on Inflammatory Markers, Muscle Damage, and Sports Performance during Acute Physical Exercise in Sedentary Individuals

“…The sample size ranged from 12 to 28 individuals. As for the study sites, three of them were conducted in Japan [ 2 , 3 , 20 ], one in China [ 21 ], and one in the United States [ 22 ]. All studies were randomized and controlled.…”

“…Thus, most studies ( n = 3; 60%) observed that treatment with curcumin could reduce CK activity, showing the benefits of curcumin supplementation in reducing pain and muscle damage by decreasing CK. Serum CK is an important clinical biomarker for muscle damage, such as muscular dystrophy, severe muscle destruction, and a marker of peripheral fatigue during physical exercises [ 21 , 22 ]. In addition, most studies ( n = 4; 80%) evaluated muscle pain; two of these (50%) reported a reduction in muscle pain.…”

Influences of Different Drop Height Training on Lower Extremity Kinematics and Stiffness during Repetitive Drop Jump

“…Data Collection. Twenty-one reflective markers (19 mm in diameter) were attached to anatomical landmarks on the legs and pelvis to define a seven-segment rigid link model of the lower extremities, according to the Helen Hayes marker set [27]. The three-dimensional (3D) trajectories of the reflective markers on the participants were collected with 10 cameras (BTS DX400, BTS Bioengineering, Milano, Italy) at a sampling frequency of 200 Hz.…”
