Caffeine consumption improves motor and cognitive performances during dual tasking in middle-aged women

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. As results, ZT, Ca and Ca + ZT intervention programs showed a significant (p < 0.05) functional performances improvement. However, Ca + ZT group showed significant (p < 0.001) better scores in terms of mobility (95%CI [0.71, 1.43]), gait speed (95%CI [0.52, 1.71]) and lower body endurance strength (95%CI [-6.93, -1.92]), except for dynamic balance (95%CI [-9.41, -3.44]). In conclusion, 12-week of Zumba training improves functional performances in middle-aged women, and daily caffeine intake is an effective alternative for improving such performances. Supplementing caffeine (100 mg/day) to Zumba training was effective in boosting Zumba benefits on these functional performances.

Music and Caffeine Intake Effects on Gait, and Its Relationship with Psychological Parameters, in Middle-Aged Women

Purpose

This study aimed to explore the combined effects of caffeine intake and listening to music on walking parameters, and its relationship with psychological variables (fatigue and exercise enjoyment) in middle-aged women.

Patients and Methods

Sixteen healthy middle-aged women, aged between 50 and 60 years old, participated in this study. Their walking parameters (distance, number of steps, steps number/minute, cadence and walking speed) were assessed using the 6-minute walking test (6MWT) in four task conditions: in no-music/no-caffeine, no-music/with caffeine, with music/no-caffeine, and with music/with caffeine conditions. Besides, exercise enjoyment and fatigue were evaluated using the Physical Activity Enjoyment Scale (PACES-8) and rating of perceived exertion (RPE) questionnaires, respectively.

Results

As a result, we found that 100 mg of caffeine intake significantly (p < 0.05) improved walking parameters such as distance, cadence and number of steps during both simple (p < 0.05) and dual-task, while listening to preferred music, where optimal results were found (p < 0.01) with a large effect size (η2p >0.14). Listening to music was sufficient to significantly improve the distance (p < 0.001), cadence (p < 0.001), and walking speed (p < 0.05) values. Besides, both caffeine intake and/or listening to music significantly (p < 0.05 with large effect size (η2p >0.14)) decreased the feeling of fatigue and increased exercise enjoyment while walking in healthy middle-aged women.

Conclusion

In conclusion, caffeine intake seems to positively influence gait capacities, and its combined effects with listening to music, mainly preferred ones, would boost these beneficial effects in middle-aged women.

Effects of coffee on cognitive function

This chapter thoroughly examines coffee's impact on cognitive function. It synthesizes research findings involving animals and humans, investigating coffee's influence on various memory and cognitive aspects, including short-term/working memory, long-term memory, attention, vigilance, executive functions, and processing speed. The chapter also discusses moderating factors, such as dose-response relationships, individual differences, age, and habitual consumption patterns, that influence the cognitive effects of coffee. Additionally, it addresses the potential risks and adverse effects associated with coffee intake, memory, and cognitive function, including stress and anxiety, sleep disturbances, cardiovascular effects, and addiction. Studies suggest moderate coffee intake improves attention, processing speed, decision-making, and certain executive functions. However, the effects vary depending on factors like dosage, individual traits, age, and sleep habits. Despite potential benefits, coffee consumption may lead to adverse effects such as anxiety, sleep issues, cardiovascular concerns, and dependency. Future research should address methodological concerns, incorporate neuroimaging methods, explore interactions with other substances, and investigate long-term effects and therapeutic uses. Understanding coffee's neuroscience can shed light on its role in daily life and health.

Potential efficacy of caffeine ingestion on balance and mobility in patients with multiple sclerosis: Preliminary evidence from a single-arm pilot clinical trial

OBJECTIVES

Caffeine's potential benefits on multiple sclerosis (MS), as well as on the ambulatory performance of non-MS populations, prompted us to evaluate its potential effects on balance, mobility, and health-related quality of life (HR-QoL) of persons with MS (PwMS).

METHODS

This single-arm pilot clinical trial consisted of a 2-week placebo run-in and a 12-week caffeine treatment (200 mg/day) stage. The changes in outcome measures during the study period (weeks 0, 2, 4, 8, and 12) were evaluated using the Generalized Estimation Equation (GEE). The outcome measures were the 12-item Multiple Sclerosis Walking Scale (MSWS-12) for self-reported ambulatory disability, Berg Balance Scale (BBS) for static and dynamic balance, Timed Up and Go (TUG) for dynamic balance and functional mobility, Multiple Sclerosis Impact Scale (MSIS-29) for patient's perspective on MS-related QoL (MS-QoL), and Patients' Global Impression of Change (PGIC) for subjective assessment of treatment efficacy. GEE was also used to evaluate age and sex effect on the outcome measures over time. (Iranian Registry of Clinical Trials, IRCT2017012332142N1).

RESULTS

Thirty PwMS were included (age: 38.89 ± 9.85, female: 76.7%). Daily caffeine consumption significantly improved the objective measures of balance and functional mobility (BBS; P-value<0.001, and TUG; P-value = 0.002) at each study time point, and the subjective measure of MS-related QoL (MSIS-29; P-value = 0.005) two weeks after the intervention. Subjective measures of ambulatory disability (MSWS-12) and treatment efficacy (PGIC) did not significantly change. The effect of age and sex on the outcome measures were also assessed; significant sex-time interaction effects were found for MSWS-12 (P-value = 0.001) and PGIC (P-value<0.001). The impact of age on BBS scores increased as time progressed (P-value = 0.006).

CONCLUSIONS

Caffeine may enhance balance, functional mobility, and QoL in PwMS. Being male was associated with a sharper increase in self-reported ambulatory disability over time. The effects of aging on balance get more pronounced over time.

Effects of 12 weeks of caffeine supplementation and Zumba training on postural balance and cognitive performances in middle-aged women

The researchers aimed to examine the effect of 12-week supplementing (100 mg/day) caffeine with Zumba training on postural and cognitive performances in middle-aged women. Fifty-six middle-aged women who participated in this study, were randomized into; a caffeine-Zumba (CZG), Zumba (ZG) and control groups. In two-testing sessions, postural balance was evaluated using a stabilometric platform, and for cognitive performances, Simple Reaction Time and Corsi Block-Tapping Task tests were used. We found that ZG and CZG showed a significant improvement in postural balance on the firm surface condition (p < .05) in the post- compared to pretest session. Whereas, ZG showed no significant improvement in postural performance on the foam surface condition. Only CZG revealed significant enhancements (p < .05) in cognitive and postural, in the foam surface condition, performances. In conclusion, supplementing caffeine with 12-week Zumba training was effective in improving both cognitive and postural balance, even in challenging conditions, performances in middle-aged women.

Quantification of Caffeine Interactions in Choline Chloride Natural Deep Eutectic Solvents: Solubility Measurements and COSMO-RS-DARE Interpretation

Solubility of active pharmaceutical ingredients is an important aspect of drug processing and formulation. Although caffeine was a subject of many studies aiming to quantify saturated solutions, many applied solvents suffer from not being environmentally friendly. This work fills this gap by presenting the results of solubility measurements in choline chloride natural deep eutectic solvents, ccNADES, comprising one of seven of the following polyalcohols: glycerol, sorbitol, xylitol, glucose, sucrose, maltose and fructose. The ratio of ccNADES components was optimized for maximizing caffeine solubility at room temperature. Additionally, temperature dependent solubility was measured for the first four systems exhibiting the highest solubility potential, both in their neat forms and in mixtures with water. Results were used for intermolecular interactions assessments using the COSMO-RS-DARE approach, which led to a perfect match between experimental and computed solubility values. An important methodological discussion was provided for an appropriate definition of the systems. Surprising linear trends were observed between the values of fitting parameters and water-ccNADES composition. In addition, comments on selection of the values of the fusion thermodynamic parameters were provided, which led to the conclusion that COSMO-RS-DARE solubility computations can effectively compensate for the inaccuracies of these important physicochemical properties.
