“…Furthermore, activity monitors should be integrated into future studies so as to better confirm the impact of physical activity guidance on both incidental and structured physical activity, in place of the subjective nature of a training diary. Given assessments were undertaken across ~48 hour period, consideration was not given to phase of menstrual cycle amongst women volunteers, given this does not influence DXA estimates of body composition (Ong et al, 2022), or any effect is trivial (Thompson et al, 2021).…”

Dual-energy X-ray absorptiometry (DXA) is a popular technique used to quantify physique in athletic populations. Due to biological variation, DXA precision error (PE) may be higher than desired. Adherence to standardized presentation for testing has shown improvement in consecutive-day PE. However, the impact of short-term diet and physical activity standardization prior to testing has not been explored. This warrants investigation, given the process may reduce variance in total body water and muscle solute, both of which can have high daily flux amongst athletes. Twenty (n = 10 males, n = 10 females) recreationally active individuals (age: 30.7 ± 7.5 years; stature: 176.4 ± 9.1 cm; mass: 74.6 ± 14.3 kg) underwent three DXA scans; two consecutive scans on 1 day, and a third either the day before or after. In addition to adhering to standardized presentation for testing, subjects recorded all food/fluid intake plus activity undertaken in the 24 hr prior to the first DXA scan and replicated this the following 24 hr. International Society of Clinical Densitometry recommended techniques were used to calculate same- and consecutive-day PE. There was no significant difference in PE of whole-body fat mass (479 g vs. 626 g) and lean mass (634 g vs. 734 g) between same- and consecutive-day assessments. Same- and consecutive-day PE of whole-body fat mass and lean mass were less than the smallest effect size of interest. Inclusion of 24-hr standardization of diet and physical activity has the potential to reduce biological error further, but this needs to be verified with follow-up investigation.

“…A hospital-grade digital ear thermometer (Braun Thermoscan 7 IRT6520 Thermometer) and digital axilla thermometer (Surgipack Digital Thermometer 6344, Vega Technologies, China) was used to validate the temperature readings from the wearable sensors. These devices are commercially available for hospital use, and they are regarded as a benchmark for temperature monitoring accuracy [ 43 , 45 ]. To receive the most accurate reference temperature readings from this device, all the measurements were conducted by an experienced registered nurse.…”

“…Our group has also previously demonstrated this method to reliably measure SAT thickness across the menstrual cycle in active eumenorrheic females (Ong et al, 2022b), as well as being robust against changes in hydration status or acute food or fluid intake (Ong et al, 2022a). This finding holds significance for standardised B‐mode US as a physique assessment method.…”

Ultrasound has been demonstrated to be a highly accurate and reliable tool for measuring subcutaneous adipose tissue thickness and is robust against changes in hydration status or acute food or fluid intake. However, the effect of prior acute exercise is unexamined. This study examined the impact of an acute endurance exercise and resistance exercise session on standardised brightness‐mode ultrasound measurements of subcutaneous adipose tissue thickness compared to skinfolds and dual‐energy X‐ray absorptiometry body composition estimates. In a randomised cross‐over design, 30 active adults (24.2 ± 4.9 years) undertook physique assessment via standardised brightness‐mode ultrasound, skinfolds and dual‐energy X‐ray absorptiometry before, immediately and 45 min after an acute endurance or resistance exercise session. The mean sum of eight subcutaneous adipose tissue thickness measured via standardised brightness‐mode ultrasound increased (0.6 mm, p = 0.04) immediately postendurance exercise but was not meaningful when evaluated against the technical error of measurement of the investigator. A significant (p = 0.01) but not meaningful decrease in the sum of eight skinfolds occurred immediately (−1.1 ± 0.4 mm) and 45 min (−1.3 ± 0.4 mm) postresistance exercise. Comparatively, endurance exercise elicited a meaningful decrease of total mass (460 ± 30 g) and trunk lean mass (680 ± 90 g) dual‐energy X‐ray absorptiometry estimates. Findings from this study indicate standardised client presentation may be unnecessary when employing either standardised brightness‐mode ultrasound or skinfolds for body composition assessment unlike dual‐energy X‐ray absorptiometry.
