Background: Time spent near V̇O2max has been suggested as an optimal stimulus for the promotion of greater V̇O2max improvements. Thus, this study aimed to compare time spent above 90% (t90V̇O2max) and 95% of V̇O2max (t95V̇O2max) during three cycling interval training protocols with decreasing, increasing, or constant work rate distributions within each exercise interval.Methods: After an incremental test to determine V̇O2max and peak power output (Ppeak), ten physically active male individuals (age 28 ± 5 years, V̇O2max 48.4...

Background: Physical inactivity has become a pressing global concern, posing significant risks to public health. University students, in particular, experience a marked decline in physical activity (PA) levels as they transition to independent living, often due to motivational, social, and environmental barriers. In the Philippines, the Commission on Higher Education has introduced the Physical Activity Towards Health and Fitness (PATHFit) program to address this concern by offering diverse activity options based on student preferences. Objective: This study aimed to explore the lived experiences of PATHFit students, focusing on how they derive meaning...

Background: Calf muscle fatigue has been shown to affect movement patterns and may contribute to increased injury risk, particularly in the knee joint. Objective: This study aims to investigate the effect of calf muscle fatigue on lower limb kinematics during cutting maneuvers in female athletes with and without dynamic knee valgus (DKV). Methods: This case-control study included female athletes with (n = 12) and without dynamic knee valgus (n = 12). The cutting maneuver kinematics were measured with 10 cameras motion analysis before and after calf muscle fatigue, which was induced using an isokinetic dynamometer through repeated maximal...
