Brain structure is a fundamental determinant of brain function, both of which decline with age in the adult. Whereas short-term exercise improves brain size in older adults, the impact of endurance training on brain structure when initiated early and sustained throughout life, remains unknown. We tested the hypothesis that long-term competitive aerobic training enhances cortical and subcortical...

The present study was designed to investigate the influences of aerobic training on the body composition, aerobic power and food intake of sedentary young females in relation to the initial levels of these variables. Thirty one untrained college females (age = 19.8 +/- 0.2 yr, stature = 154.4 +/- 0.8 cm, body mass = 53.3 +/- 1.2 kg, mean +/- SEM) participated in an exercise regimen consisting o...

This study evaluated the effects of 6 weeks of high-intensity interval training (HIIT) on mechanical efficiency (ME) in young and older groups. Seventeen healthy young adults [26.2(2.4) year], and thirteen healthy older adults [54.5(2.3) year] completed a 6-week HIIT intervention (three sessions per week) on an electromagnetically braked cycle ergometer. Each HIIT session contained six repetiti...

BACKGROUND Public health initiatives world-wide recommend increasing physical activity (PA) to improve health. However, the dose and the intensity of PA producing the most benefit are still debated. Accurate assessment of PA is necessary in order to 1) investigate the dose-response relationship between PA and health, 2) shape the most beneficial public health initiatives and 3) test the effecti...

Rendahnya kemampuan fisik siswa khususnya daya tahan aerobik di SMPN 1 Sampang, tujuan pelaksanaan riset ini ialah untuk memahami ada ataupun tidak pengaruhnya metode latihan interval with mini hurdle dan fartlek time to distance terhadap peningkatan VO2max. Pelaksanaan mempergunakan jenis penelitian eksperimen dengan desain two-group pretest-posttest. Sampel yang dipakai 20 Sampang dibagi menj...

Poor cardiorespiratory fitness (CRF) is an important risk factor for age-related diseases including cardiovascular disease, cancer, dementia and osteoporosis. When evaluated through active metabolism test reported as VO2Max, or the maximal oxygen uptake during intense exercise, CRF a highly valued functional marker to assess overall wellness disease in elderly. For every 3.5ml/kg/min increase V...

We previously showed that after seven generations of artificial selection of rats for running capacity, maximal O2 uptake (VO2max) was 12% greater in high-capacity (HCR) than in low-capacity runners (LCR). This difference was due exclusively to a greater O2 uptake and utilization by skeletal muscle of HCR, without differences between lines in convective O2 delivery to muscle by the cardiopulmon...

OBJECTIVE To establish the level of cardiorespiratory fitness and the rate of decrease in maximal aerobic capacity according to age in patients with chronic low back pain and compare these with normative data. DESIGN Prospective case series with historical controls. SUBJECTS/PATIENTS Seventy patients with chronic low back pain. METHODS A maximal cycle ergometer protocol was used to measur...

Mitochondrial function in human skeletal muscle declines with age. Most evidence for this decline comes from studies that assessed mitochondrial function indirectly, and the impact of such deterioration with respect to physical function has not been clearly delineated. We hypothesized that mitochondrial respiration in permeabilized human muscle fibers declines with age and correlates with phosp...
