4-Week intervention combining kiwifruit consumption and small-sided soccer games improves sleep quality in children with overweight/obesity and pre-existing sleep problems.

Childhood obesity is a global public health concern associated with various health risks, including disrupted sleep patterns. This study investigated the effects of kiwifruit consumption and small-sided soccer games (SSSG) over 4 weeks on sleep patterns in overweight/obese children with sleep problems. Thirty-six participants, aged 8 to 12 years with a body mass index above the 85th percentile, were randomly assigned to one of three groups: SSSG only ( = 12), SSSG-kiwifruit (SSSG-K,  = 12), or control (CG,  = 12).

Effects of Various Caffeine Doses on Cognitive Abilities in Female Athletes with Low Caffeine Consumption.

Caffeine (CAF), a prevalent psychoactive stimulant, is believed to potentially enhance cognitive ability. However, studies on the effects of various doses are limited and yield inconsistent results, particularly in female athletes. Therefore, we aimed to assess the association between three different dosages of CAF intake (low, moderate, and high) and cognitive skills in female athletes with low CAF consumption.

Impaired muscle oxygenation despite normal pulmonary function in type 2 diabetes without complications.

Long-term hyperglycemia in individuals with type 2 diabetes (T2D) can detrimentally impact pulmonary function and muscle oxygenation. As a result, these factors can impede the body's adaptation to physical exertion. We aimed to evaluate the oxygen pathway during maximal exercise among overweight/obese individuals with type 2 diabetes free from complications, in comparison with a group of matched overweight/obese individuals without diabetes, specifically concentrating on the effects on pulmonary function and muscle oxygenation.

Using artificial intelligence for exercise prescription in personalised health promotion: A critical evaluation of OpenAI's GPT-4 model.

The rise of artificial intelligence (AI) applications in healthcare provides new possibilities for personalized health management. AI-based fitness applications are becoming more common, facilitating the opportunity for individualised exercise prescription. However, the use of AI carries the risk of inadequate expert supervision, and the efficacy and validity of such applications have not been thoroughly investigated, particularly in the context of diverse health conditions.

Optimizing Short-Term Maximal Exercise Performance: The Superior Efficacy of a 6 mg/kg Caffeine Dose over 3 or 9 mg/kg in Young Female Team-Sports Athletes.
