Research has indicated that low-to-moderate dosages of caffeine supplementation are ergogenic for sustained endurance efforts as well as high-intensity exercise. The effects of caffeine supplementation on strength-power performance are equivocal, with some studies indicating a benefit and others demonstrating no change in performance. The majority of research that has examined the effects of caffeine supplementation on strength-power performance has been carried out in both trained and untrained men. Therefore, the purpose of this study was to determine the acute effects of caffeine supplementation on strength and muscular endurance in resistance-trained women.

Introduction: Healthcare providers play a crucial role in promoting sexual health among older adults, an important yet often neglected aspect of aging well. Although sexuality evolves beyond the reproductive years, it remains a meaningful part of life for many. Despite the natural decline in sexual activity with age, numerous older adults continue to value and engage in fulfilling sexual relationships. Unfortunately, targeted interventions to support later-life sexuality are lacking, creating gaps in care. Intervention: Sexuality in older adults is influenced by biological, psychological, and social factors. Clinicians should include comprehensive sexual health assessments, including STI screenings, as part of routine care. Providing age-appropriate sexual education and resources helps promote lifelong sexual wellness. Open communication between healthcare providers and patients is vital for addressing sexual concerns, often left unspoken due to stigma or discomfort. Additionally, adopting lifestyle medicine principles—such as balanced nutrition, regular exercise, stress management, and social connection—can enhance sexual health and overall well-being. Conclusion: Specialized training for healthcare professionals on the unique aspects of older adult sexuality is essential to bridge knowledge gaps. A holistic, evidence-based approach will empower providers to better support the evolving sexual health needs of older adults, improving their quality of life.

The purposes of the study were to: (1) identify judgments college students make of peers based on descriptions of drinking, hooking-up, and condom use behaviors; and (2) determine whether participants' judgments differed based on the sex of the person described. Participants (N = 574 college students) completed an online questionnaire that included one of 8 different vignettes (4 vignette types, female or male model). Participants evaluated statements, comprising 3 scales (likability, positive character, negative behavior) relative to the model depicted in the vignette. For female participants, significant effects for vignette type for all 3 scales and significant effects for model sex (negative behavior) were revealed. Male participants only showed significant effects for vignette type for positive character traits. Results should be of value to college level health educators and considered by those involved in drinking behavior and sexual health programming on college campuses.

The prevalence of overweight and obesity among youth has increased markedly in the past 2 decades in the United States. According to the Centers for Disease Control and Prevention, in 2010, more than one-third of children and adolescents were overweight or obese. A number of obesity prevention and intervention programs focus on the individual by utilizing intrapersonal theories to encourage the individual to eat healthy and participate in physical activity. The purpose of the current article is to go beyond the individual level and approach obesity with an ecological perspective because it may prove to have a larger influence. The ecological systems theory (EST) by Bronfenbrenner postulated that human development is influenced by a reciprocal relationship between the individual and their social system. In the context of physical activity, health behaviors occur within and are influenced by the multiple systems within which youth reside. This manuscript explores Bronfenbrenner’s EST framework comprising 4 systems: microsystem, mesosystem, exosystem, and macrosystem. Each level of the system is explored and applied to the obesity epidemic among youth.

Introduction: Sexual well-being is a cornerstone of overall health and life satisfaction. It is shaped by an intricate interplay of psychological, physiological, and sociocultural factors. Therefore, comprehensive sexual health assessments should be integral to routine medical care. These evaluations must include a detailed review of sexual history, sexual functioning, and the effects of medications. Interventions: Enhancing sexual satisfaction involves multiple strategies, including sexual health education, individual or couples counseling, and therapy. Promoting healthy lifestyle choices, managing chronic illnesses, and fostering open dialogue between healthcare providers and patients are essential. There is also an increasing need to equip healthcare professionals with advanced training to address sexual health concerns in aging populations. Conclusion: Improving sexual well-being among older adults requires a holistic approach. Continued research is crucial to better understand the psychosexual factors that influence sexual satisfaction and enhance quality of life in later years.
