'conditions' => array(
    'competition_id' => $id,
    intval($logger['Competitor']['weight']) . ' BETWEEN weight_min AND IF(weight_max > 0, weight_max, 1000)',
    intval($logger['Competitor']['height']) . ' BETWEEN height_min AND IF(height_max > 0, height_max, 1000)',
    intval(date('Y') - substr($logger['Competitor']['dateofbirth'], 0, 4)) . ' BETWEEN age_min AND IF(age_max > 0, age_max, 100)',
    'gender' => $logger['Competitor']['gender'],
    intval($logger['Competitor']['grade']) . ' BETWEEN grade_from AND IF(grade_to > 0, grade_to, 100)',
)
