| Abstract |
The aim of this study was to expand exercise testing in handcycling by (1) examining different approaches to determine lactate kinetics in handcycling under various exercise modalities and (2) identifying relationships between parameters of lactate kinetics and selected performance measures. Twelve able-bodied nationally competitive triathletes performed a familiarisation, a sprint test, an incremental step test, and a continuous load trial at a power output corresponding to a lactate concentration (La) of 4 mmol l-1 (PO4) in a racing handcycle that was mounted on an ergometer. During the tests, La and heart rate (HR) were determined. As performance measures, maximal power output during the 15-s All-Out sprint test (POmax,AO15) and maximal power output during the incremental test (POmax,ST) were determined. As physiological parameters, coefficients of lactate kinetics, maximal lactate accumulation rate ([Formula: see text]Lamax), maximal La following the sprint test and incremental test (Lamax,AO15, Lamax,ST) and the increase in La within the last 20 min of the continuous trial (LaCrit,CT) were determined. Mean values of POmax,AO15 (545.6 ± 69.9 W), POmax,ST (131.3 ± 14.9 W), PO4 (86.73 ± 12.32 W), [Formula: see text]Lamax (0.45 ± 0.11 mmol l-1 s-1), Lamax,AO15 (6.64 ± 1.32 mmol l-1), Lamax,ST (9.64 ± 2.24 mmol l-1) and LaCrit,CT (0.74 ± 0.74 mmol l-1) were in accordance to literature. [Formula: see text]Lamax was positively correlated with Lamax,AO15 and POmax,AO15 and negatively correlated with POmax,ST. POmax,ST was negatively correlated with Lamax,AO15. PO4 was negatively correlated with Lamax,ST. [Formula: see text]Lamax was identified as a promising parameter for exercise testing in handcycling that can be supplemented by other parameters describing lactate kinetics following a sprint test. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 August 2018.
All research outputs
#17,292,294
of 25,382,440 outputs
Outputs from European Journal of Applied Physiology
#3,318
of 4,345 outputs
Outputs of similar age
#219,138
of 338,967 outputs
Outputs of similar age from European Journal of Applied Physiology
#41
of 53 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,345 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 14.7. This one is in the 16th percentile – i.e., 16% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 338,967 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 53 others from the same source and published within six weeks on either side of this one. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
