search with larger sample sizes is needed to better understand the fitness determinants of backs' RHIE ability.
The aim of this study was to compare the power profile, internal and external workloads, and racing performance between U23 and professional cyclists and between varying rider types across 2 editions of a professional multistage race.
Nine U23 cyclists from a Union Cycliste Internationale "Continental Team" (age 20.8 [0.9]y; body mass 71.2 [6.3]kg) and 8 professional cyclists (28.1 [3.2]y; 63.0 [4.6]kg) participated in this study. Rider types were defined as all-rounders, general classification (GC) riders, and domestiques. Data were collected during 2 editions of a 5-day professional multistage race and split into the following 4 categories power profile, external and internal workloads, and race performance.
The professional group, including domestiques and GC riders, recorded higher relative power profile values after certain amounts of total work (1000-3000kJ) than the U23 group or all-rounders (P ≤ .001-.049). RTA-408 ic50 No significant differences were found for external workload measures between U23 and prof into the professional ranks, as well as differentiate between rider types.
To assess the value of monitoring changes in fitness in professional soccer players, using changes in heart rate at submaximal intensity (HR12km/h) over the velocity at a lactate concentration of 4mmol/L (v4mmol/L). The authors reexamined (1)a range of threshold magnitudes, which may improve detecting substantial individual changes and (2)the agreement between changes in these 2 variables.
On at least 2 occasions during different moments of the season, 97 professional soccer players from Germany (first, second, and fourth division) completed an incremental test to determine HR12km/h and v4mmol/L. Optimal thresholds for changes in HR12km/h and v4mmol/L were assessed, using various methods (eg,smallest worthwhile change + typical error [TE], successive reiterations approach). Agreement between both variable changes was examined for the whole sample (225 comparisons), 4 different subgroups (depending on the moment of the season), and in an individual over 6 years (n = 23 tests).
Changes of 4.5% and 6.0% fotly implement short, 3-minute submaximal runs, with 4.5% changes in HR12km/h being indicative of true substantial fitness changes, with 60% to 78% accuracy. Future studies should investigate the potential role of confounding factors of HR12km/h to improve changes in fitness prediction.
This study aimecd to investigate whether elite athletes could reach higher values of maximal oxygen uptake (V˙O2max) during a decremental exercise test in comparison with a traditional incremental test, as recently demonstrated in trained individuals.
Nine male runners (age 25.8 [5.1]y, season best 10-km time 3119 [150]) performed, on different days, 3 maximal uphill (5% grade) running exercise tests in fixed order an incremental test (INC1), a V-shape exercise test (where speed started at 0.5km·h-1 higher than the top stage finished during INC1 and was slowly decreased during 5.5min, when it was again increased in similar fashion to the INC tests), and a final incremental test (INC2).
V˙O2max during the V-shape exercise test was higher than during INC1 (6.3% [3.0%], P = .01), although running speed was lower (16.6 [1.7] vs 17.9 [1.6]km·h-1, P = .01). Performance was similar between INC1 and INC2, but V˙O2max during INC2 was higher than INC1 (P < .001). During the V-shape exercise test, 5 participants reached the incremental part of the test, but V˙O2 did not increase (ΔV˙O2=52 [259] mL·min-1, P = .67), despite higher running speed (approximately 1.1km·h-1, P < .01). Heart rate, pulmonary ventilation, breathing rate, and respiratory exchange ratio measured at V˙O2max were not different between tests.
A decremental exercise test of sufficient intensity can produce higher V˙O2max than a traditional incremental test, even in elite athletes, and this is maintained during a subsequent incremental test.

To investigate the effects of caffeine (CAF) on performance during high- and long-jump competitions.
Using a crossover and double-blind design, 6 well-trained high jumpers and 6 well-trained long jumpers performed a simulation of a high- and long-jump competition 60minutes after ingesting a capsule containing either 5mg·kg-1 body mass of anhydrous CAF or a placebo. The high jumps were video recorded for kinematic analysis. The velocity during the approach run of the long jump was also monitored using photocells.
CAF improved jump performance (ie,the highest bar height overlap increased by 5.1% [2.3%], P = .008), as well as enhancing the height displacement of the central body mass (+1.3% [1.7%], P = .004) compared with the placebo. CAF had no ergogenic effect on jump distance (P = .722); however, CAF increased the velocity during the last 10m of the long jump (P = .019), and the percentage of "foul jumps" was higher than that expected by chance in the CAF group (80.5% [12.5%], χ2 = 13.44, P < .001) but not in the cellulose condition (58.3% [22.9%], χ2 = 1.48, P = .224).
CAF ingestion (5mg·kg-1 body mass) improves high-jump performance but seems to negatively influence technical aspects during the approach run of the long jump, resulting in no improvement in long-jump performance. Thus, CAF can be useful for jumpers, but the specificity of the jump competition must be taken into account.

Here, the authors describe explicit efforts by the neurosurgery community to empower and expand representation of women in neurosurgery, among which they identified four themes 1) formal mentorship channels; 2) scholarships and awards; 3) training and exposure opportunities; and 4) infrastructural approaches. Ultimately, a data-driven approach is needed to improve representation and empowerment of women in neurosurgery and to best direct the neurosurgical community's efforts across the globe.
