The Relationship Between Variables in Wearable Microtechnology Devices and Cricket Fast-Bowling Intensity.
Open accessAbstract
To date, the monitoring of fast-bowling workloads across training and competition environments has been limited to counting total balls bowled. However, bowling at faster velocities is likely to require greater effort while also placing greater load on the bowler. This study investigated the relationship between prescribed effort and microtechnology outputs in fast bowlers to ascertain whether the technology could provide a more refined measure of workload. Twelve high-performing fast bowlers (mean ± SD age 20.3 ± 2.2 y) participated in the study. Each bowler bowled 6 balls at prescribed bowling intensities of 60%, 70%, 85%, and 100%. The relationships between microtechnology outputs, prescribed intensity, and ball velocity were determined using polynomial regression. Very large relationships were observed between prescribed effort and ball velocity for peak PlayerLoad™ (R = .83 ± .19 and .82 ± .20). The PlayerLoad across lower ranges of prescribed effort exhibited a higher coefficient of variation (CV) (60% = 19.0% [17.0-23.0%]), while the CV at higher ranges of prescribed effort was lower (100% = 7.3% [6.4-8.5%]). Routinely used wearable microtechnology devices offer opportunities to examine workload and intensity in cricket fast bowlers outside the normal metrics reported. They offer a useful tool for prescribing and monitoring bowling intensity and workload in elite fast bowlers.

Current practices stipulate that the total number of deliveries bowled, irrespective of the length of spell or delivery, be used as a tool to monitor bowling load.
“Current practices stipulate that the total number of deliveries bowled, irrespective of the length of spell or delivery, be used as a tool to monitor bowling load [15,18,41].”
From The Effects of an Eight over Cricket Bowling Spell upon Pace Bowling Biomechanics and Performance within Different Delivery Lengths (2019) · cites this paper as [18]
The Discussion (page unavailable) says that bowling workload in cricket literature and practice has been measured by counting balls bowled in training and competition. This supports the claim about using total deliveries to monitor load, but the paper does not specify that the count is used irrespective of spell length or delivery length. (LLM, conf=0.83)
Experimental — accuracy not yet measuredThe sample size attained in this study (n = 11) is similar to those implemented in previous simulated cricket fast-bowling research.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
