“…The trends in plasma Hx concentration in our endurance 1-year training study are similar to those observed in shortduration sprint training (Hellsten-Westing et al 1993a, b;Stathis et al 1994;Spencer et al 2004). In our study, the lowest postexercise concentration of Hx was observed during the competition phase when the proportion of anaerobic training loads was highest, that is the training was characterized to a larger extent by high-intensity exercises.…”

“…This reXects the muscle adaptation which reduces in turn adenine nucleotides loss (Hellsten-Westing et al 1993a, b). Similar results were obtained by Stathis et al (1994) in active but nonspeciWcally trained subjects (men and women) and Spencer et al (2004) in elite female Weld hockey players. Stathis et al (1994) demonstrated signiWcant diVerences in muscle and plasma Hx concentration between the trained and the non-trained group as well as between the pre-and post-training values after a 7-week sprint training.…”

“…There was no performance change after training (no changes in power and fatigue index were observed). In contrast to this, the research of Spencer et al 2004 on female national Weld hockey players revealed a considerable decrease of resting (as well as postexercise) Hx concentration after training lasting for 7 weeks. This suggests that changes in resting concentrations occur only after a longer period of training.…”

“…Lowered concentration of plasma purines after training allows athletes to exercise more intensively without the loss of purine nucleotide. The study on the eVects of a 7-week Weld hockey-speciWc training on repeated-sprint ability, plasma Hx concentration and other blood parameters in 18 elite female Weld hockey players revealed a signiWcant decrease in plasma Hx concentration (posttest minus rest values) (Spencer et al 2004). The authors suggest that one adaptation of sport-speciWc repeated-sprint training may be to conserve the purine nucleotide pool.…”

The purpose of the study was to characterize the changes in purine metabolism in long-distance runners in the main phases of their 1-year training cycle. Nine male athletes competing in distances 5 and 10 km at national/regional level, mean age 22.9 +/- 0.6 years, practising sport for 8.6 +/- 0.3 years, participated in the study. The changes in plasma concentrations of hypoxanthine (Hx), xanthine (X) and uric acid (UA) and the activity of the enzyme HGPRT in red blood cells haemolysate were followed in four characteristic points of the annual training cycle: preparatory phase (specific subphase), competition period, transition period and preparatory phase (intermediate subphase). Resting and postexercise plasma concentrations of X and, Hx and HGPRT activity changed significantly during 1-year training cycle. Significant changes in postexercise Hx values between training phases were found, from 9.3 micromol l(-1) in competition period to 22.9 micromol l(-1) in transition period (Friedmann's ANOVA, P < 0.01). Postexercise UA values ranged from 371 to 399 micromol l(-1) and did not change significantly between training phases. An increase in resting (from 52.0 to 58.4 IMP mg(-1) Hb min(-1), P < 0.05) and postexercise (from 70.7 to 76.2 IMP mg(-1) Hb min(-1), not significant) HGPRT activity between the specific preparation and competition period was observed. In the transition period, Hx postexercise concentration increased (22.9 micromol l(-1), P < 0.01) and HGPRT postexercise activity decreased (58.8 IMP mg(-1) Hb min(-1), P < 0.01) significantly. The results indicate that the level of plasma Hx at rest and after standard exercise may be a useful tool for monitoring the adaptation of energetic processes in different training phases and support the overload/overtraining diagnosis.

“…That, in turn, led to a decrease in the ability to perform shortterm physical exercises by female field hockey players [4]. According to Spencer et al [5], such an adverse ten dency may be, to a large extent, prevented in part by following a 7-week strength-training plan, which result ed in a significant reduction of hydrogen ion produc tion in the body. At the same time, Bishop & Spencer [6] observed a decrease in the concentration of hypox anthine, which is formed in the body as a byproduct of damage to purine nucleotides.…”

Purpose. Using databases available on the Internet, the number of scientific papers on the subject of field hockey were examined. Basic procedures. As a result, 208 scientific studies covering the fields of biochemistry, physiology, sport injuries, psychology and tactics were found, which were published within the last 50 years (from 1960 to 2010). Despite the popularity of field hockey and its status as an Olympic sport, the number of scientific studies which focused on field hockey was much smaller when compared to the amount of publications on other team sports, such as soccer, basketball, or baseball. Main findings. It was found that the greatest number of pub lications (61.06%) originated from five English-speaking countries (UK, USA, Canada, Australia, and New Zealand), with the majority focusing on sport psychology, injuries and biochemistry. What was discovered was that the vast majority of scientific studies used field hockey merely as a reference point in comparison to other team sports. Conclusions. The varying topic diversity of the scientific stud ies found among the databases significantly hinders an effective comparison of findings, especially considering that most of the studies focused on only a few selected aspects of the problem matter and were chiefly small sample studies, nor were they repeated.

Performance and physiological responses to repeated-sprint exercise: a novel multiple-set approach

et al. 2010

We investigated the acute and chronic responses to multiple sets of repeated-sprint exercise (RSE), focusing on changes in acceleration, intermittent running capacity and physiological responses. Ten healthy young adults (7 males, 3 females) performed an incremental test, a Yo-Yo intermittent recovery test level1 (Yo-Yo IR1), and one session of RSE. RSE comprised three sets of 5 × 4-s maximal sprints on a non-motorised treadmill, with 20 s of passive recovery between repetitions and 4.5 min of passive recovery between sets. After ten repeated-sprint training sessions, participants repeated all tests. During RSE, performance was determined by measuring acceleration, mean and peak power/velocity. Recovery heart rate (HR), HR variability, and finger-tip capillary lactate concentration ([Lac(-)]) were measured. Performance progressively decreased across the three sets of RSE, with the indices of repeated-sprint ability being impaired to a different extent before and after training. Training induced a significant increase (p < 0.05) in all indices of performance, particularly acceleration (21.9, 14.7 and 15.2% during sets 1, 2 and 3, respectively). Training significantly increased Yo-Yo IR1 performance by 8% and decreased Δ[Lac(-)]/work ratio (-15.2, -15.5, -9.4% during sets 1, 2 and 3, respectively) and recovery HR during RSE. There were strong correlations between Yo-Yo IR1 performance and indices of RSE performance, especially acceleration post-training (r = 0.88, p = 0.004). Repeated-sprint training, comprising only 10 min of exercise overall, effectively improved performance during multiple-set RSE. This exercise model better reflects team-sport activities than single-set RSE. The rapid training-induced improvement in acceleration, quantified here for the first time, has wide applications for professional and recreational sport activities.
