KINES 260 Lab 2

Introduction

Previous research (Church, Wiggins, Moode, & Crist, 2001) have found that static stretching has been shown to acutely reduce power and muscular endurance. In contrast, some types of high intensity, activity-specific movements, increase subsequent athletic performance (Hrysomallis & Kidgell, 2001). Baker (2003) suggests that for sports requiring explosive strength, a warm-up should be utilized.

Method

Participants

The members of the KINES 260 class were randomly assigned to one of three groups: static stretch (1), jog and squat (2), or Control (3).

Instruments

.

Procedures.

I. Standing Long Jump

a. Stand behind a known or marked area on the gymnasium floor (toes directly on the line)

b. Feet shoulder width apart, toes lined up

c. Swing your arms a bit and get your body ready for takeoff

d. Lean forward slightly, and bend your knees to a bit above parallel

e. Explode up and out with your legs and swing your arms forward

f. Have a partner mark the where you land

g. NOTE – measurement is taken from the line to where the heel touches

II. Random assignment to each group:

J&S: Jog around the gym for 2 laps and perform 2 sets of 3 reps of star jumps.

C: Control group will help stretching group.

S: Perform 2 sets of 15s hold lying hamstring stretches on each leg.

III. Repeat vertical jump test.

Group	Age	Gender	Pre_Jump	Post_Jump

Give instructor the pre mean and post mean long jump score as well as gender (1=male, 2=female) age and group.

Results

Analysis of Variance

1. Run a 2x3 (genderXgroup) factorial ANOVA on the long jump change score. Determine whether the groups are significantly different. Write up the results in APA Format.

Discussion

Summarize the findings and make decisions regarding the hypotheses. Describe weaknesses and limitations in our experimental design. Make suggestions for improving the design with future research.
