Alterations in kinetic patterns of pedal force and crank torque due to changes in surface grade (level vs. 8% uphill) and posture (seated vs. standing) were investigated during cycling on a computerized ergometer. Kinematic data from a planar cine analysis and force data from a pedal instrumented with piezoelectric crystals were recorded from multiple trials of 8 elite cyclists. These measures were used to calculate pedal force, pedal orientation, and crank torque profiles as a function of crank angle in three conditions: seated level, seated uphill, and standing uphill. The change in surface grade from level to 8% uphill resulted in a shift in pedal angle (toe up) and a moderately higher peak crank torque, due at least in part to a reduction in the cycling cadence. However, the overall patterns of pedal and crank kinetics were similar in the two seated conditions. In contrast, the alteration in posture from sitting to standing on the hill permitted the subjects to produce different patterns of pedal and crank kinetics, characterized by significantly higher peak pedal force and crank torque that occurred much later in the downstroke. These kinetic changes were associated with modified pedal orientation (toe down) throughout the crank cycle. Further, the kinetic changes were linked to altered nonmuscular (gravitational and inertial) contributions to the applied pedal force, caused by the removal of the saddle as a base of support.

Background:

There are many purported benefits to recess including engaging in physical activity, forming positive peer relationships, and taking a break from the classroom. Current research, however, is inconclusive regarding the presence of gender and developmental differences in physical activity that takes place during recess. The purpose of this study was to examine differences in the amount of physical activity that occurs during recess across gender and grade level.

Methods:

Students from first- and sixth-grade classrooms participated in the study, and physical activity was measured using accelerometers to record the number of steps taken during recess.

Results:

A 2 × 2 factorial ANOVA indicated sixth grade males engaged in more physical activity than sixth grade females, first grade males, and first grade females.

Conclusions:

Because they are not engaging in as much physical activity as their sixth grade male counterparts, ways to help female and younger students take more steps during recess should be explored.
