Current pregnancy exercise guidelines primarily recommend at least 150 min of moderate-intensity physical activity per week and provide limited specific guidance on vigorous- and high-intensity exercise in highly trained pregnant women. High-intensity exercise can elevate core temperature (Tcore), raising concerns about maternal hyperthermia and potential fetal risks (e.g. neural tube defects, preterm birth, fetal growth restriction). Accurate monitoring of maternal Tcore may be necessary to evaluate safety. However, pregnancy-related cardiovascular and thermoregulatory adaptations, such as changes in skin blood flow and heat dissipation, may affect temperature estimates, yet few non-invasive and user-friendly methods combine accuracy with practicality during exercise.

Low-load training with blood flow restriction (BFR-LRT) has emerged as an alternative that uses lower mechanical loads but greater repetition volume to induce metabolic stress. While these training modalities impose differing physiological demands, the extent to which they produce comparable adaptations in highly trained athletes remains unclear. This study aimed to compare the effects of a 6-week BFR-LRT program versus a traditional HRT program on upper-body maximal strength and strength endurance in male collegiate gymnasts.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;Thirty male collegiate gymnasts completed the experiment in three parallel groups: HRT (3 sets of 10 repetitions at 75% 1-repetition maximum [1RM]), BFR-LRT (1 set of 30 and 3 sets of 15 repetitions at 30% 1RM), or a control group (CG) that performed only regular gymnastics training. The 6-week intervention was preceded by familiarization and reliability testing. Upper-body maximal strength (1RM for bar dip, pull-up, and shoulder press) and strength endurance (maximal repetitions for bar dips 60s, pull-ups 40s, and handstand push-ups 40s) were assessed at baseline and post-intervention. A one-way Analysis of Covariance (ANCOVA), with baseline scores as a covariate, was used to compare post-intervention outcomes. To formally interpret non-significant comparisons between the HRT and BFR-LRT groups, a follow-up Bayesian ANCOVA was performed. Additionally, mediation analysis was conducted to determine if improvements in maximal strength mediated the observed gains in strength endurance.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;Both HRT and BFR-LRT produced significantly greater improvements than the control group across all outcomes.
