Walking Fatigue and Balance Study in Females (**Now offering gift card upon completion**)
The focus of the research team is on the influence of aging, disuse, fatigue, and resistance training on skeletal muscle and nervous system function. This research involves collaboration between undergraduate and graduate students as well as other faculty in a team setting that emphasizes critical thinking and hands-on experience. We use several laboratory tools to comprehensively investigate neuromuscular properties such as muscle strength, muscle explosiveness, skeletal muscle size, skeletal muscle quality, and muscle activation.
There is the potential for students to join our team as a volunteer. Academic credit may be earned through ES 3398: Internship in Exercise Science or BIOL 4400: Directed Study. If an ES major, assisting with research can be used towards your required 1 credit hour internship. If sincerely interested in assisting with research, contact me at firstname.lastname@example.org.

- Measures strength and velocity for various muscle groups during isometric, isokinetic, and eccentric muscle actions
Digitimer Constant Current Stimulator
- Electrically stimulates the nerve or muscle for the study of involuntary contractions to determine muscle (peripheral) and nervous system (central) changes
- Provides measures of skeletal muscle size and quality
Portable Force Plate and Wireless EMG
- Measures ground reaction forces and muscle activation during practical movements (chair rise, jumping)
- Measures postural stability and provides fal risk index during static and dynamic tests
