Caffeine optimizes Zumba training benefits on functional performances in middle-aged women: a randomized trial study.

The current study aimed to explore the effect of daily caffeine supplementation (100 mg/day) and 12-week of Zumba training on functional performances in middle-aged women. Eighty-five middle-aged women were randomized into 4 groups including control, Zumba training (ZT), caffeine supplementation (Ca) or caffeine-Zumba training (Ca + ZT) groups. Functional performances were assessed using 10 m Walk, Timed Up and Go, Functional Reach, and 30-Second Chair Stand tests.

Biocomposite Material Based on sp. Immobilized in Natural Polymer Matrix for Pharmaceutical Removal from Aqueous Media.

Ecosystems are negatively impacted by pharmaceutical-contaminated water in different ways. In this work, a new biosorbent obtained by immobilizing in a calcium alginate matrix was developed for the removal of pharmaceuticals from aqueous solutions. Ethacridine lactate (EL) was selected as the target drug.

Use of vegetable oils as dielectric fluids for electrical discharge machining. A case study.

Electrical discharge machining with solid electrodes represents an efficient solution to generate blind cavities with complex geometry. Vegetable oils represent an alternative to conventional dielectrics, which are considered harmful for the environment and human health. This study tested the feasibility of two widely used vegetable oils, sunflower and soybean, under intense machining of three alloys with application in aeronautic industry, aiming for high process productivity and a good surface quality.

The Impact of Aerobic Dance Intervention on Postural Balance in Children: A Randomized Controlled Trial.

This study aimed to investigate the impact of an 8-week aerobic dance intervention on postural balance in children. Forty-one children, aged 9 to 11, were randomly assigned to either an aerobic dance group (ADG) or a control group (CG) from a primary school. Postural balance was assessed using center of pressure (CoP) excursions before and after the 8-week intervention period.

Effects of Smartphone Activities on Postural Balance in Adolescents with Intellectual Disabilities.

Considering the rising prevalence of smartphone usage among adolescents with intellectual disabilities and their frequent motor challenges, understanding its impact on their physical well-being is important. This study aims to investigate the impact of smartphone activities on postural balance in adolescents with intellectual disabilities. Two groups of adolescents participated in the study: an intellectual disability group (IDG) ( = 16) and atypical development group (TDG) ( = 12).

The Impact of Peripheral Vision on Manual Reaction Time Using Fitlight Technology for Handball, Basketball and Volleyball Players.

The purpose of the research was to identify the impact of peripheral (unilateral and bilateral) vision on manual reaction time to visual stimuli in handball, basketball and volleyball players by implementing a 6-week experimental program of specific exercises and some adapted tests using Fitlight technology. The research included 412 players (212 male-51.5%; 200 female-48.

Training in Hypoxia at Alternating High Altitudes Is a Factor Favoring the Increase in Sports Performance.

Training above 1800 m causes increases in hemoglobin, erythropoietin and VO2max values in the bodies of athletes. The purpose of this study is to prove that living at an altitude of 1850 m and training at 2200 m (LHTH+) is more effective than living and training at 2000 m (LHTH). Ten endurance athletes (age 21.

The Effects of Small-Sided Games and Behavioral Interventions on the Physical and Motivational Outcomes of Youth Soccer Players.

The objective of this study was to test the effects of two types of intervention, one based on small-sided games (SSGs), and the other one that had, in addition, a behavioral component consisting of goal setting, public posting, and positive reinforcement. The participants were 16 male soccer players aged 12-14 years old who participated in a couple of training sessions per week between August and November 2021. We used Playr Catapult GPS devices to assess the effect of the intervention on the total distance covered and total sprint distance in the task of playing SSGs.
