The coronavirus disease (COVID-19) has led to an acceleration of innovative technological ideas in the sporting industry. People had to learn to adapt and make changes in their sporting habits or physical activity (PA) during lockdown. Purpose: This study investigated the effects of COVID-19 on the levels of PA and sporting industry in Singapore. A total of 1,000 participants (≥21 years old) volunteered in this virtual survey. The survey collected participants’ levels of PA according to exercise intensity and type of PA. The findings revealed that 61.5% of participants (n = 795) participated in PA and expended more than 500 METs-minute/week. 23.8% of participants had an increase in PA, 40.3% of participants maintained their PA and 25.5% of participants had a decrease in PA. 49.6% of participants used online visual programmers (OVP) as part of their PA. More individuals are utilising OVP and home sporting equipment in place of their usual exercise facilities. Sporting industries are switching to virtual platforms to further engage consumers, which may have ensued in the increase in PA for 23.8% of participants. Therefore, this may have resulted in an increase or sustainability of revenue for certain sporting industries (e.g., gym equipment).

BACKGROUND: The purpose of this study was to identify a normalized RPE response at ventilatory breakpoint (Vpt) for male adolescents 13-17 years old, and whether these adolescents could self-regulate at target RPEs of 4 and 6.
METHODS: Twenty healthy males participated in the study, with 10 males in each of the cycling and walking/running groups. Participants performed orientation and V̇O2peak trials before performing a perceptual estimation exercise trial to obtain RPE Vpt, and two production trials to assess self-regulation ability.
RESULTS: Vpt corresponded to 67.7% V̇O2peak for the cycling group and 70.4% V̇O2peak for the walking/running group. There were no group differences on RPE-Overall Vpt (cycling: 4.6; walking/running: 4.4), RPE-Legs Vpt (cycling: 5.4; walking/running: 4.6), and RPE-Chest Vpt (cycling: 4.0; walking/running: 4.8). A normalized RPE-Overall Vpt response was identified at five. V̇O2 did not differ between the estimation and production trials at targets RPE of 4 (1.59 vs. 1.57 L·min-1) and 6 (1.87 vs. 1.79 L·min-1). Similarly, heart rate (HR) did not differ between estimation and production trials at targets RPE 4 (152.4 vs. 151.1 beats·min-1) and 6 (167.1 vs. 162.4 beats·min-1). Both V̇O2 and HR were significantly higher at RPE 6 compared to RPE 4. Responses were not affected by exercise mode or production sequence.
CONCLUSIONS: This study demonstrated that undifferentiated and differentiated RPE Vpt were similar between cycling and walking/running participants. Male adolescents between 13- and 17-year-olds were able to use the OMNI scale to self-regulate exercise intensities that would be useful in field settings.
