Repeated sprint ability

Cian McGinley, David John Bishop
This study measured the adaptive response to exercise training for each of the acid/base transport protein families, including providing isoform-specific evidence for the monocarboxylate transporter (MCT)1/4 chaperone protein basigin and for the electrogenic sodium/bicarbonate cotransporter (NBCe)1. We investigated whether 4 weeks of work-matched, high-intensity interval training (HIIT), performed either just above the lactate threshold (HIITΔ20; n = 8), or close to peak aerobic power (HIITΔ90; n = 8), influenced adaptations in acid/base transport protein abundance, non-bicarbonate muscle buffer capacity (βmin vitro), and exercise capacity in active men...

BACKGROUND: Numerous studies have analyzed during competitive season different conditioning programs to improve soccer players' repeat sprint ability (RSA). However, few studies have focused on analysing what happens with this ability after small-sided games (SSG)-based training. Thus, the aim of this study was to determine the changes in physical performance after 5-weeks of pre-season training composed of SSGs in amateur soccer players. METHODS: Twenty-four male soccer players performed RSA, a sit-and-reach and two vertical jump (squat and counter movement jump) tests before and after 5-weeks of pre- season training using fundamentally SSGs...

The main objective of this study was to characterize the occurrence of single sprint and repeated-sprint sequences (RSS) during elite female soccer matches, using fixed (20 kmh) and individually based speed thresholds (>90% of the mean speed from a 20 m sprint test). Eleven elite female soccer players from the same team participated in the study. All players performed a 20 m linear sprint test, and were assessed in up to 10 official matches using Global Positioning System (GPS) technology. Magnitude-based inferences were used to test for meaningful differences...

The aim was to analyze the effect of two different plyometric training programs (i.e., one vs. two sessions per week, same total weekly volume) on physical performance in futsal players. Forty-four futsal players were divided into three training groups differing in weekly plyometric training load: the two days per week plyometric training group (PT2D, n=15), the one day per week plyometric training group (PT1D, n=12) and the control group (CG, n=12) which did not perform plyometric training. The results of this study showed that in-season futsal training per se was capable of improving repeat sprint ability (RSA) (ES=-0...

It has been reported that nitrate supplementation can improve exercise performance. Most of the studies have used either beetroot juice or sodium nitrate as a supplement; there is lack of data on the potential ergogenic benefits of an increased dietary nitrate intake from a diet based on fruits and vegetables. Our aim was to assess whether a high-nitrate diet increases nitric oxide bioavailability and to evaluate the effects of this nutritional intervention on exercise performance. Seven healthy male subjects participated in a randomized cross-over study...

BACKGROUND: The ability to perform repeated sprints is likely influenced by the mode of the recovery. Despite performance time, peak power, and mean power measured in most of studies, there are other specific sport abilities that should be examined after different recovery strategies.The aim of this study was to examine the effects of recovery modes (active [AR] vs passive [PR]) on physiological performance (lactate, HR, and blood pressure), psychological performance (perceived exertion rating [RPE] and feeling scale [FS]), and specific skills (kicking accuracy [KA] and repeated dribbling) in young soccer players...

PURPOSE: Repeated-sprint training in hypoxia (RSH) has been shown as an efficient method for improving repeated sprint ability (RSA) in team-sport players but has not been investigated in swimming. We assessed whether RSH with arterial desaturation induced by voluntary hypoventilation at low lung volume (VHL) could improve RSA to a greater extent than the same training performed under normal breathing (NB) conditions. METHODS: 16 competitive swimmers completed six sessions of repeated sprints (two sets of 16x15 m with 30 s send-off) either with VHL (RSH-VHL, n=8) or with NB (RSN, n=8)...
