Brief Summary

This study will utilize a combination of cardiovascular analysis, 3D motion capture, and a software package, Metrifit, to monitor measures of well-being to comprehensively evaluate both the musculoskeletal and physiological responses following a HIIT training intervention at EOC as a means of improving performance and potentially reducing injury risk factors. This holistic approach of physiological and biomechanical factors is unprecedented. This is the first interventional study to determine the effect of high intensity training at EOC on cardiovascular performance, kinematics and well-being which may minimize risk of injury factors.

Eligibility Criteria

• Age: 18 Years - 89 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• An experienced cyclist will be defined as one with at least 5 years of cycling experience and 5000 miles of training on a road bike with a clipless pedal system.
• Able to tolerate strenuous, maximal exercise and comply with a 6 week training protocol
• Have access to an indoor trainer or spin bike with a cadence sensor in order to train 3 times per week for 60 minutes

You may not qualify if:

• Taking medication which could impact cardiovascular function or performance (stimulants, beta-blockers, e.g.)
• Significant cardiac or pulmonary disease (congenital cardiac disease, uncontrolled hypertension, uncontrolled asthma, e.g.)
• Musculoskeletal injuries that preclude a maximal cycling effort and participation in training program
