Objective: Resistance training has been shown to have positive effects on increasing muscle mass and strength in healthy individuals. Athletes of all different backgrounds are always seeking new ways to maximize strength gains to maximize performance. The purpose of this study was to examine the effects of tactile cues on individuals progressing through a six-week strength training program. Participants: Male college students (n = 18) aged (21±1.46) participated in an experiment testing the effect of lower extremity tactile cues and muscular strength. Outcome measure: Anthropometric variables were recorded: age, height, body weight, body mass index, body fat percentage and fat free mass. Muscle strength was assessed by a 1-repetition maximal leg extension test (1 RM) using a standard leg extension machine. Subjects were then randomized to either the control or the experimental tactile cues group. Both groups were asked to perform knee extensions twice a week on nonconsecutive days during their own prescribed strength training program. Each subject was instructed to perform a predetermined amount of repetitions that corresponded with 50% of their 1-RM test. During the strength training the experimental group preformed detailed tactile cues provided by the PI when they were preforming their weekly leg extension exercises. Post 1-RM was assessed the following sixth week of strength training. Results: Height was found to be statistically different between the control and experimental groups (p<.05). No significance was observed for the other anthropometric variables (p>.05). It was observed that the experimental group displayed a statistically significant difference in mean strength following the six weeks of tactile cues (p = .022) compared to the control group. Conclusion: This study indicates that prescribed tactile cues for a leg extension exercise can have a significant effect on increasing muscular strength following six weeks on implementation during a strength training program.
