Purpose: To investigate the effect of different limb blood-flow levels on cycling-performance recovery, blood lactate concentration, and heart rate. Methods: Thirty-three high-intensity intermittent-trained athletes completed two 30-s Wingate anaerobic test sessions, 3 × 30-s (WAnT 1–3) and 1 × 30-s (WAnT 4), on a cycling ergometer. WAnT 1–3...

As soluble intercellular adhesion molecule-1 (sICAM-1) was recently hypothesized to be a key player in the mechanisms involved in exercise-induced muscular damage (EIMD), we investigated its circulating concentration changes in athletes before and after EIMD with and without the use of whole-body cryostimulation (WBC; 3 min at −110 °C) at the...

Introduction.-The purpose of this study was to test the reproducibility of the Fitmate TM metabolic system in measuring breathing gas during a cycling exercise.Synthesis of the facts.-Twenty-one participants performed during two sessions three 5-min exercises at submaximal intensities (16, 18 et 21 km/h). The reproducibility of respiratory...

Aim.- The purpose of this study was to analyze the effectiveness of supplementation in vitamin on the maximal muscular performance in master athletes during a strength training program.Method.- Twenty well-trained master athletes took part in a three weeks strength training program and in a same time in a micro nutritional supplementation...

Aims: This review focuses first of all on the effects of the cold and/or contrast water immersion techniques on muscular recovery to determine practical implications for athletes. Then, the present review summarizes the effects of whole-body cryotherapy and its potential benefits.Actualities: The multitude of protocols concerning the cold water...

The influence of vitamin and mineral complex supplementation on muscular activity and cycling efficiency was examined in elderly endurance-trained master athletes during a heavy cycling trial. Master athletes were randomly assigned in a double-blind process to 1 of 2 treatment groups: antioxidant supplementation (n = 8: As group) or placebo (n...

The purpose of this study was to test the effect of a three-week strength training program of knee extensor muscles on cycling delta efficiency in master endurance athletes. 9 master (age: 51.5 ± 5.5 yr) and 8 young (age: 25.6 ± 5.9 yr) endurance athletes with similar training levels participated in this study. During 3 consecutive weeks, all...

Context : Electric muscle stimulation has been suggested to enhance recovery after exhaustive exercise by inducing an increase in blood flow to the stimulated area. Previous studies have failed to support this hypothesis. We hypothesized that the lack of effect shown in previous studies could be attributed to the technique or device...

The purpose of this study was to examine the relationship between strength capacity and preferred and optimal cadence in well trained cyclists. Eighteen cyclists participated in this study. Each subject completed three sessions. The initial session was to evaluate the maximal isokinetic voluntary contraction level of lower limb. The second...

Purpose: To assess the impact of between-training-sessions recovery strategies (passive [PAS], active [ACT], cold-water immersion [CWI], and ingestion of a recovery drink [NUTR]) on maximal cycling performance, perceptions of delayed-onset muscle soreness (DOMS), and fatigue in world-class BMX riders. Methods: Eleven elite BMX athletes, members...

The aim of this study was to investigate the effects of regular post-exercise whole-body cryotherapy (WBc) on physiological and performance adaptations to high-intensity interval training (Hit). in a two-group parallel design, twenty-two well-trained males performed four weeks of cycling HIT, with each session immediately followed by 3 min of...

Objective: To assess whether Ramadan intermittent fasting (RIF) affects 5000m running performance and physiological parameters classically associated with middle distance performance.Design: Eighteen subjects (age 23.6±2.9 yr, body mass 64 ± 2.3 kg) divided in two experimental groups (Ramadan fasting (n = 9 vs. control, n= 9) participated in...

The aim of this study was twofold: i) to analyze age-related declines in swimming, cycling, and running performances for Olympic and Ironman triathlons, and ii) to compare age-related changes in these three disciplines between the Olympic and Ironman triathlons. Swimming, cycling, running and total time performances of the top 10 males between...

Purpose: The purpose of this study was to investigate the influence of different cycling cadences on metabolic and kinematic parameters during subsequent running.Methods: Eight triathletes performed two incremental tests (running and cycling) to determine maximal oxygen uptake (V̇O2max) and ventilatory threshold (VT) values, a cycling test to...

To determine the acute effects of a trail running competition and the age-dependent differences between young and master athletes, 23 subjects [10 young (30.5 ± 7 years), 13 master (45.9 ± 5.9 years)] participated in a 55-km trail running competition. The study was conceived as an intervention study compromising pre, post 1, 24, 48 and 72 h...

The aim of the present study was to determine the best pacing strategy to adopt during the initial phase of a short distance triathlon run for highly trained triathletes. Ten highly trained male triathletes completed an incremental running test to determine maximal oxygen uptake, a 10-km control run at free pace and three individual time-trial...
