International Journal of Exercise Science
International Journal of Exercise Science 16(5): 1012-1024, 2023. Emerging evidence suggests that outdoor group exercise may reduce stress more than indoor group exercise because the outdoor environment provides unique mental health benefits. Stress leads to illnesses and diseases, but exercise mitigates harmful impacts. This study explored differences in perceived stress and outdoor physical activity participation among college students in an indoor or outdoor group exercise class. Data were collected pre-, mid- (after four sessions), and post-intervention (after eight sessions). Seventeen participants indicated an interest in the study, but 13 signed up. Participants completed a four-week group exercise intervention that met …

International Journal of Exercise Science 16(7): 814-827, 2023. Home-based video exercise interventions improve older adults’ physiological performance and functional capacity. Little is known about the energy costs of video exercises in older adults. The Compendium of Physical Activities (PAs) has few items with PA metabolic equivalents (METs) in older adults. This study measured the energy costs of four chair and two standing exercises (sitting Tai Chi, Yoga, mobility ball, aerobics: standing, slow aerobics, and fast aerobics). Fifteen females and 14 males, 62-87 years (M ± SD, 73 ± 7.7 years), were categorized into three age groups (60-69, 70-79, 80-89). Oxygen …
Body Mass Index But Not Physical Activity Level Moderates Lowered Cardiac Baroreflex Sensitivity In People Living With Hiv, Marcus Rangel, Juliana Barros, Deysiane Peres, Pedro Mira, Daniel Martinez, Mateus Laterza, Paulo Farinatti, Juliana Borges
Body Mass Index But Not Physical Activity Level Moderates Lowered Cardiac Baroreflex Sensitivity In People Living With Hiv, Marcus Rangel, Juliana Barros, Deysiane Peres, Pedro Mira, Daniel Martinez, Mateus Laterza, Paulo Farinatti, Juliana Borges
International Journal of Exercise Science
International Journal of Exercise Science 16(2): 700-709, 2023. Reduced cardiac baroreflex sensitivity (cBRS) is an autonomic marker associated with a worse cardiovascular prognosis. Whether cBRS is lowered in people living with HIV (PLHIV) is yet unclear, as well as potential moderator effects of body mass index (BMI) or physical activity (PA) level. The present study aims to compare the spontaneous cBRS in PLHIV vs. HIV-uninfected controls, and to determine among PLHIV the relationship between cBRS vs. body mass index (BMI) and PA level. Total, upward (cBRS+), and downward (cBRS-) cBRS gains were assessed using the sequential method from beat-to-beat …
