Study Description:

We are inviting you to participate in an online experiment that will take about 45 minutes of your time. We are hoping to gather data from undergraduate students at McMaster University to assess whether the casual video game Microsoft Jewel can lead to therapeutic effects and induce a flow state. The goal is to compare the potential therapeutic effects of playing Microsoft Jewel to browsing the internet, both for 20 minutes. The game is playable on a web browser. Before and after either playing Microsoft Jewel or browsing the internet, you will be asked to complete surveys to measure your mood and stress. Additionally, at the end of the study, you will also be asked to complete a survey to measure your flow state, a psychological state of intense focus.

Study Description:

We’re testing whether time-efficient interval training affects heart and artery health differently between males and females. You will perform 12 weeks of sprint interval training, 3 times per week. Each session takes 10 minutes to complete, and consists of: 3 x 20-second sprints on a stationary bike with 2 minutes of rest in between, plus a brief warm-up and cool-down. We will measure heart and artery function at baseline, and after 4 and 12 weeks of training.

Eligible Participants:

– Aged 18-35 years
– Engaging in less than 1 hour of weekly structured aerobic training
– A VO2peak of less than 38 and 48 ml/kg/min for females and males, respectively

Compensation: $150
