Influence of circadian rhythm and body temperature on grip strength and selected physiological variables of college women baseball players

Abstract

The primary purpose of this study was to find the relationship between circadian rhythm type and body temperature on grip strength right hand (R), grip strength left hand (L), average grip strength (AVG), pulse rate, blood pressure (Diastolic) and blood pressure (systolic). In order to achieve the above-mentioned objectives, sixteen (16) female Baseball team members undergoing B. Tech graduation course at College of Engineering, Thiruvanathapuram, Kerala, India were tested. The instruments used include Morningness-Eveningness in human circadian rhythms questionnaire (Horne J.A and Ostberg 1976), digital blood pressure monitor, digital Thermometer and electronic hand dynamometer. After determining the circadian type, body temperature, grip strength right(R), grip strength left (L) pulse rate, blood pressure (diastolic) and blood pressure (systolic) were recorded. ANOVA results and post-hoc test on dependent variables grip strength (Right), grip strength (L) and grip strength average found no significant differences among the independent variable body temperature. The result also shows that dependent variable grip strength (Right) found having significant differences between independent variables circadian rhythm type.
