UNLABELLED Skeletal muscle-derived interleukin-6 (IL-6) is a pleiotropic cytokine which regulates body metabolism during strenuous physical exercise. OBJECTIVE The effect of a potentially functional single nucleotide polymorphism (SNP) -174G/C of the IL6 gene (rs1800795) promoter was examined on maximal oxygen uptake (VO2max), body mass index (BMI) and plasma IL-6 levels in response to physic...

Lately, the effect of quercetin supplementation (QS) on endurance performance (EP) and maximal oxygen consumption (VO2max) has been receiving much scientific and media attention. Therefore, a meta-analysis was performed to determine QS's ergogenic value on these variables. Studies were located with database searches (PubMed and SPORTDiscus) and cross-referencing. Outcomes represent mean percent...

The purpose of this study was to develop a standardized and externally paced field test (15-m Incremental Shuttle Walk and Run Test [15mISWRT]), incorporating an incremental and progressive structure, to assess aerobic fitness in middle-aged adults. 68 middle-aged men performed three tests in random order between one to two week intervals: 15-m ISWRT, cardiopulmonary exercise test (CPX), and 15...

We investigated the effects of acute endurance exercise and habitual physical activity for health maintenance on human neutrophil function in 12 untrained men. The acute exercise condition was a continuous exercise for 90 minutes at the intensity of 50% and 55% of maximal oxygen uptake (VO2max) on an ergometer. The training program was 3 km jogging three times per week for 8 weeks. The capacity...

PURPOSE The training response of an intensified period of high-intensity exercise is not clear. Therefore, we compared the cardiovascular adaptations of completing 24 high-intensity aerobic interval training sessions carried out for either three or eight weeks, respectively. METHODS Twenty-one healthy subjects (23.0±2.1 years, 10 females) completed 24 high-intensity training sessions througho...

AIMS To evaluate motor performance and cardiorespiratory function in youths with type 1 diabetes in comparison with age-matched control groups and to analyze the influence of physical activity level, anthropometric and physical fitness parameters on long-term metabolic control. METHODS 106 youths with diabetes and 130 healthy youths aged 8-18 were assessed by the Eurofit test regarding motor ...

This cross-sectional study evaluated the relationships between anthropometric and aerobic fitness (rate of perceived exertion [RPE] predicted maximal oxygen uptake [VO2max]) among 228 participants (age: 23.78±4.42 years). RPE VO2max were determined during cycle ergometer exercise test. Data also obtained for height, weight, body mass index (BMI), hip waist (WC) circumferences. analysis reveale...

The aim of this study was to investigate the maximal oxygen uptake (VO2MAX) determined using the incremental phase of the lactate minimum test (LM) on a cycle ergometer. Fifteen trained men were submitted to a graded exercise test (GXT) to evaluate the VO2MAX and LM. The total durations of the GXT and LM were 11.2±1.8 minutes (CI95%:10.2-12.3 minutes) and 25.3±3.2 minutes (CI95%:23.5-27.0), res...

ABSTRACT Introduction: The severe exercise intensity domain can be defined as the range of work rates or speeds over which VO2max elicited. Objectives: Our purpose was to determine if critical speed (running analog power) identifies lower boundary and identify upper domain. Methods: Twenty-five individuals performed five running tests exhaustion, each lasting > 2.5 min < 16 min. two-param...

Based on the author's observations in field, it shows that VO2max capacity of MUTU FA Kebumen futsal players is still low. This possible due to lack precise training methods used by trainers process. study aims see effect extensive interval and fartlek players. research method a quasi-experimental (quasi experimental). The population this was 30 people, while sample taken purposive sampling so ...
