Brief Summary

The goal of this study is to investigate the acute effects of cricket fast bowling on the bone turnover and signaling markers in healthy young males.

The main question aims to answer:

• Does a single bout acute fast bowling change serum C-terminal telopeptide of type I collagen (CTX-I) and other bone turnover and signaling markers levels?

Participants complete both the bowling and control trials, with a minimum washout period of one week between trials. During each trial, blood samples are collected at three time points: pre-, immediately post, and 2-hour post bowling/rest.

Study Groups

Arm Bowling + Control

Participants first perform the bowling trial, followed by the control trial, with a minimum interval of one week between the two trials.

Group Type: EXPERIMENTAL

Exercise

Intervention Type: BEHAVIORAL

During the bowling trial, participants perform 8 sets of 6 deliveries (bowl at match intensity throughout), followed by 2-hour rest. Each set is interspersed by a 3-minute randomized fielding simulation. During the control trial, participants rest throughout instead of bowling.

Arm Control + Bowling

Participants first perform the control trial, followed by the bowling trial, with a minimum interval of one week between the two trials.

Group Type: EXPERIMENTAL

Exercise

Intervention Type: BEHAVIORAL

During the bowling trial, participants perform 8 sets of 6 deliveries (bowl at match intensity throughout), followed by 2-hour rest. Each set is interspersed by a 3-minute randomized fielding simulation. During the control trial, participants rest throughout instead of bowling.
