We hypothesized that all-out running speeds for efforts lasting from a few seconds to several minutes could be accurately predicted from two measurements: the maximum respective speeds supported by the anaerobic and aerobic powers of the runner. To evaluate our hypothesis, we recruited seven competitive runners of different event specialties and tested them during treadmill and overground runni...

The aim of this study was to investigate the effects of Ramadan fasting on anaerobic power and capacity and the removal rate of lactate after short time high intensity exercise in power athletes. Ten male elite power athletes (2 wrestlers, 7 sprinters and 1 thrower, aged 20-24 yr, mean age 22.30 ± 1.25 yr) participated in this study. The subjects were tested three times [3 days before the begin...

The aim of the study was to examine the physical and physiological differences as dependent on age of young wrestlers. One hundred and twenty-six 15 – 17 year old wrestlers volunteered as subjects in the present study. The physical and physiological profiles included body weight, height, body mass index, flexibility, anaerobic power, aerobic endurance, strength, speed, and body composition. The...

In Part 11 of the study, the British Olympic track (sprint) squad cyclists demonstrated reductions in body fat index, % body fat and endomorphy (p > .05), increased Hb and PCV % (p > .05), and lowered HR at rest and in warm-up exercise (p > .05), but no change in leg power. Repeated interval sprints of short duration, maximal exercise on an "ergowheel" ergometer, at standardised power output, s...

Background/Aim. The Wingate anaerobic test is a valid and reliable method of measuring anaerobic capacity. The aim of this study was to determine whether other modified test can be used instead of the Wingate test. Methods. A group of 30 sedentary young men were first tested with a cycle ergometer (classic Wingate test), and then with a dynamometer during 30 s of “all out” leg extension exercis...

This study examined the extent to which aerobic power could account for performance during a 30-s max-effort test. Physically active women (n = 41) and men (n = 34) underwent a treadmill test for aerobic power and the Wingate test for anaerobic power and fatigue. Pearson product-moment correlation coefficients were calculated from Wingate segments of various durations and temporal positions. Fo...

Six men performed a total of 23 modified Wingate power tests against 5.5 kp (53.9 N) resistance on a Monark 864 ergometer. Breath-by-breath VO2 was measured using a SensorMedics 4400 metabolic cart. Peak anaerobic power (highest 5 s; mean(s.e.m.)) was 819(16) W (11.1(0.6) W kg-1) and anaerobic capacity (work in 30 s; mean(s.e.m.)) was 18.2(0.2) kJ (248(11) J kg-1). Contributions of ATP-PC, glyc...

In Part II of the study, the British Olympic track (sprint) squad cyclists demonstrated reductions in body fat index, % body fat and endomorphy (p greater than .05), increased Hb and PCV % (p greater than .05), and lowered HR at rest and in warm-up exercise (p greater than .05), but no change in leg power. Repeated interval sprints of short duration, maximal exercise on an "ergowheel" ergometer...

the effect of protein supplementation on athletic performance and hormonal changes was examined in 32 experienced collegiate strength/power athletes participating in a 12-week resistance training program. method: subjects were randomly assigned to either a protein supplement (pr; n = 22) or a placebo (pl; n = 10) group. during each testing session subjects were assessed for strength (one repet...
