Previous research has shown that various modes of exercise may elicit significant increases in resting metabolism for up to 24 hours post-exercise, but typically using untrained or moderately active subjects. The purpose of the present study was to compare excess post-exercise oxygen consumption (EPOC) between circuit-style resistance training (RT) and high-intensity interval training (HIIT) in young, aerobically fit women. During the follicular phase of the menstrual cycle, seven participants reported to the laboratory for evening and morning baseline resting metabolic rate (RMR) measurements via indirect calorimetry. Participants fasted and slept overnight in the laboratory between RMR measurements. Following the morning RMR measurement, participants were randomly assigned to complete either a total-body, circuit-style RT protocol (30 seconds of lifting at 80% 1RM:one minute rest) or treadmill HIIT (30-second run at 90% VO2 max:one minute stationary recovery). RMR was repeated 14 and 24 hours post-exercise. All procedures were replicated during the follicular phase of the next menstrual cycle using the remaining exercise protocol. Resting VO2 was significantly (p<0.05) higher 14 hours after RT (3.8±0.3 ml/kg/min) compared to baseline (3.4±0.3 ml/kg/min), however HIIT showed no significant change (3.7±0.3 ml/kg/min). Both RT and HIIT showed significantly higher energy expenditure 14 hours post-exercise (33±5 and 33±4 kcals/30 minutes, respectively) compared to baseline (30±3 kcal). Neither protocol sustained a RMR change at 24 hours. Based on the magnitude and duration of post-exercise energy expenditure, EPOC responses may be a worthwhile consideration when prescribing exercise for weight maintenance in young, fit women.

EPOC Comparison Between Resistance Training and High-Intensity Interval Training in Aerobically Fit Women

有氧适能女性中抗阻训练与高强度间歇训练的EPOC比较

Research is inconclusive regarding the association between aerobic fitness (objectively measured VO2max) and repeated sprint performance when the sprints are less than 40 meters. Soccer athletes must be able to repeat sprints without significant decreases in speed and strength and conditioning coaches need to better understand if aerobic fitness is related to repeated sprint ability (RSA). Twenty (10 male, 10 female) Division I soccer athletes first completed a graded maximal treadmill test to measure VO2max. Then on a separate day, athletes completed the RSA test. The RSA test consisted of 10, 30-meter sprints which athletes repeated every 30 seconds. There were significant negative correlations (r ≤ -0.69, P < 0.001) between VO2max and all 10-sprint times and average sprint time. More aerobically fit Division I soccer athletes were faster at all time points during the RSA test. Aerobic fitness is associated with faster sprint times during a more anaerobic RSA test when sprint distances are less than 40 meters.

Aerobic Capacity is Related to Repeated Sprint Ability with Sprint Distances Less Than 40 Meters.

有氧能力与短于40米的重复短跑能力相关。

Gravel cycling is a relatively new cycling discipline, with the Union Cycliste Internationale (UCI) hosting their first World Championships in 2022. Gravel races combine features of road racing, cyclocross, and mountain biking, including terrain of varying technical difficulty, long distances, substantial elevation gain, obstacles, and limited opportunities to stop for in-race nutrition. This study assessed hydration responses to gravel races of three different distances. Data were collected on saliva osmolarity (SOsm), body mass (BM), fluid intake, and nutrition knowledge at a gravel cycling race in April 2023. A total of 121 participants completed pre-race surveys, 53 provided pre-race measures of BM and SOsm, and 38 participants completed post-race testing. Only 22.6% (n = 12) of participants were hydrated before the race, with 56.6% mildly dehydrated (n = 30), 18.9% moderately dehydrated (n = 10), and 1.9% severely dehydrated (n = 1). Post-race, 15% (n=6) were still hydrated, 20% (n = 8) were mildly dehydrated, 47.5% (n = 19) were moderately dehydrated, and 17.5% (n = 7) were severely dehydrated. Analyses revealed significant decreases in BM and increases in SOsm from pre- to post-exercise in the two longer race distances (p &lt; 0.05). There was a significant effect of race distance on energy, fluid, carbohydrate, and sodium intake (p &lt; 0.05). Sweat rates were not different (p &gt; 0.05). Our results revealed an effect of race distance on BM losses, SOsm, and energy, fluid, carbohydrate, and sodium intakes. Future studies could inform optimal feeding and hydration strategies.

Intake of fruits and vegetables (F&amp;V) is related to health outcomes. The purpose of the study was to test an online diet program promoting F&amp;V intake among healthy adults. Twenty-three participants were randomly assigned to complete an 8-week intervention condition (#800gChallenge®) or wait-list control condition. In weeks 1-4, intervention participants were asked to interact with an application reporting (a) whether they met their daily 800g F&amp;V goal, (b) if their 800g of F&amp;V was from a variety of sources, and (c) reading of daily educational material. Weeks 1-4 included weekly Zoom check-in meetings. Weeks 5-8 were autonomous, wherein participants reported in the application information regarding their 800g F&amp;V goal. At baseline, 4-weeks, and 8-weeks, the participants were prompted to complete three Automated Self-Administered Dietary Assessment tool (ASA24) 24-hour diet recalls for generating Healthy Eating Index (HEI) scores indicating diet quality. A two-way ANOVA was used to examine differences between the intervention and control groups in HEI total score, total vegetable, total fruit, and whole fruit component scores at baseline, 4-weeks, and 8-weeks. While no statistically significant differences in HEI scores were observed between groups, the intervention group showed promising improvements over the 8-week period. Notably, the intervention group increased their mean HEI total score, along with substantial gains in their total vegetable and total fruit consumption, indicating the intervention’s potential for promoting healthier dietary patterns. These findings underscore the need for ongoing research to develop eHealth interventions of optimal duration and intensity that can drive meaningful improvements in the health of adults with poor diet quality.

Law enforcement agencies typically have recruits complete fitness assessments without personal protective equipment (PPE). PPE negatively impacts performance. Greater strength and power could alleviate performance decrements due to the extra load, termed the tactical deficit (TD). The purpose of this study was to examine whether lower-body strength or power related to the TD in civilians performing police tasks. Twenty participants (12 men, 8 women) completed baseline tests, including: standing broad jump (SBJ); relative SBJ; absolute and relative isometric leg/back dynamometer (LBD) and one-repetition maximum hexagonal bar deadlift (HBD). In two other sessions, participants completed four police tasks, either unloaded or loaded (PPE=~8-10 kg), in a counterbalanced order: vertical jump (VJ), 75-yard pursuit run (75PR), 74.84-kg body drag, and 500-yard run. The VJ was also used as a power metric, with peak anaerobic power and power:body mass (P:BM) derived. Paired samples t-tests investigated differences between unloaded/loaded conditions for each task for each sex. Independent samples t-tests compared the sexes. Pearson’s correlations derived relationships between strength and power tests with each task TD for each sex. Load negatively impacted task performance (p≤0.011); males generally outperformed females (p≤0.044). Superior SBJ, relative SBJ, VJ, P:BM, and absolute and relative HBD related to a smaller 75PR TD (r=-0.582 to -0.838). Greater absolute and relative HBD related to a lower body drag TD (r=-0.576 to -0.618) in men. For women, the relative SBJ related to a smaller VJ TD (r=-0.727). Developing lower-body strength and power could offset TD in foot pursuit and dragging tasks for personnel.

Visual processing is crucial for sports performance, influencing athletes' ability to interpret and respond to visual stimuli. This study investigated distinct visual processing patterns among Thai elite athletes in gymnastics, soccer, and esports, utilizing visual P300 event-related potentials (P300 ERPs). Forty-two female athletes (14 gymnasts, 14 soccer players, and 14 esports athletes) participated. Visual P300 ERP responses were stimulated using the visual oddball paradigm. One-way ANOVA was employed to assess significant differences among the groups in P300 ERPs data, including amplitude and latency of waveforms, response time, and accuracy rate. Significant differences were found across the groups in various parameters. Esports athletes exhibited longer P300 ERP latencies at the frontal electrode sites compared to gymnasts (p = 0.01), suggesting slower visual processing in the frontal brain regions. Gymnasts demonstrated the fastest response times, significantly quicker than esports and soccer players (p &lt; 0.01). In contrast, soccer players exhibited the highest accuracy rate (p = 0.03). These findings underscore athletes' diverse visual processing strategies in different sports contexts, reflecting sport-specific adaptations. Understanding these distinct visual processing patterns can guide targeted interventions aimed at improving cognitive abilities and decision-making processes among elite athletes, ultimately contributing to better overall performance.
