Context: Supplementing with fruits high in anthocyanins to reduce exercise-induced oxidative stress and inflammation has produced mixed results.
Objective: This systematic review and meta-analysis aims to discuss the impact of whole fruits high in anthocyanins, including processing methods and the type and amount of fruit, on inflammation and oxidative stress.
Data Sources: PICOS reporting guidelines and a customized coding scheme were used to search 5 databases (SPORTDiscus, Science Direct, Web of Science [BIOSIS], Medline [Pubmed], and the Cochrane Collaboration) with additional cross-referencing selection.
Purpose: The purposes of this study were to examine the performance on the progressive aerobic cardiovascular endurance run (PACER) test in children with and without attention-deficit hyperactive disorder (ADHD) over the course of a school year, and also to investigate the possible influence of age, sex, school sport participation, and body mass index on results.
Methods: Utilizing a repeated measures design, 892 middle school children aged 11-14 years (mean = 12.25, SD = 0.
To test the hypotheses that erythropoietin (rhuEPO) treatment increases systemic hematocrit, maximal O2 uptake (VO2max, by elevated perfusive and diffusive O2 conductances) and performance five female horses (4-13 years) received 15 IU/kg rhuEPO (erythropoietin) three times per week for three weeks. These horses had been splenectomized over 1 year previously to avoid confounding effects from the mobilization of splenic red blood cell reserves. Each horse performed three maximal exercise tests (one per month) on an inclined (4°) treadmill to the limit of tolerance; two control trials and one following EPO treatment.

Asthma is also a leading cause of school absenteeism, and thus of concern to physical educators and health professionals. The purpose of this study was to assess aerobic performance by children with and without asthma.

Forty male National Collegiate Athletic Association Division I hockey players were tested on the following performance variables: vertical jump (VJ), standing broad jump, 40-yard dash, and maximal back squat (SQT). The subjects also performed 3 skating tests: the 90-ft forward acceleration test, the 90-ft backward acceleration test, and the 50-ft flying top speed test (F50).

Aerobic capacity reflects consumption of O2 by working muscles during vigorous physical activity and is an indicator of cardiovascular health. This study examined change in aerobic performance by children in Grades 4 to 8 (Ages= 9-14) over 14 mo. 105 healthy children in a small, rural, middle-class school participated.

Therefore, the purpose of this study was to investigate any differences in muscle myosin heavy chain (MHC) and body composition associated with aging. Twenty-three young (4-8 years) and eight old (20+ years) unfit Standardbred mares were evaluated.
