Exercise physiology is the study of how the body responds acutely and chronically to exercise; it is a subdiscipline of the multidisciplinary field of kinesiology. An important focus of basic and applied scientific research on exercise is the identification of the underlying physiological

When conducting physiology research that involves the testing of human participants, there can be a seemingly endless number of methodological decisions related to experimental design, sampling/recruitment, protocol and analysis. One particularly important aspect to consider is the standardisation
Physiological Responses and Perceived Exertion During International Taekwondo Competition
Craig A. Bridge, Michelle A. Jones, and Barry Drust
Purpose:
To investigate the physiological responses and perceived exertion during international Taekwondo competition.
Methods:
Eight male Taekwondo black belts (mean ± SD, age 22 ± 4 y, body mass 69.4 ± 13.4 kg, height 1.82 ± 0.10 m, competition experience 9 ± 5 y) took part in an international-level Taekwondo competition. Each combat included three 2-min rounds with 30 s of recovery between each round. Heart rate (HR) was recorded at 5-s intervals during each combat. Capillary blood lactate samples were taken from the fingertip 1 min before competition, directly after each round and 1 min after competition. Competitors’ rating of perceived exertion (RPE) was recorded for each round using Borg’s 6-to-20 scale.
Results:
HR (round 1: 175 ± 15 to round 3: 187 ± 8 beats·min−1; P < .05), percentage of HR maximum (round 1: 89 ± 8 to round 3: 96 ± 5% HRmax; P < .05), blood lactate (round 1: 7.5 ± 1.6 to round 3: 11.9 ± 2.1 mmol·L-1; P < .05) and RPE (round 1: 11 ± 2 to round 3: 14 ± 2; P < .05; mean ± SD) increased significantly across rounds.
Conclusions:
International-level Taekwondo competition elicited near-maximal cardiovascular responses, high blood lactate concentrations, and increases in competitors' RPE across combat. Training should therefore include exercise bouts that sufficiently stimulate both aerobic and anaerobic metabolism.

Intracyclic Variation of Force and Swimming Performance
Pedro G. Morouço, Tiago M. Barbosa, Raul Arellano, and João P. Vilas-Boas
The mainstream procedure to monitor elite swimmers’ performance is to conduct either physiological or biomechanical assessments. With the assessments performed separately, it is challenging to provide a well rounded and holistic insight of the swimmer’s performance (ie, swimming speed). Swimming

The sleeping period is an ideal time in which noninvasive wearable devices can quantify physiological biomarkers of recovery and readiness due to the paucity of external confounding variables such as eating and ambulation. In addition, because sleep is primarily a stationary activity, wearable devices
Dietary Supplements for Athletic Performance in Women: Beta-Alanine, Caffeine, and Nitrate
Molly J. Murphy, Blake R. Rushing, Susan J. Sumner, and Anthony C. Hackney
Dietary supplements marketed as “ergogenic aids” are increasingly popular among international and U.S. collegiate and elite-level athletes. Ergogenic dietary supplements are promoted with claims of enhancing performance by improving strength, endurance, or other physiological attributes, though the
