Isometric and Isotonic Hand Strengthening in Competitive Female Badminton Athletes

This randomized clinical trial aims to determine the effects of targeted isometric and isotonic hand strengthening exercises on hand function, dexterity, grip strength and grip endurance in competitive female badminton athletes aged 18-30 years. Participants will be randomly allocated into two groups receiving either isometric or isotonic hand strengthening exercise programs performed three times per week for six weeks. Outcome measures will be assessed at baseline, 3rd week and 6th week using Michigan Hand Outcomes Questionnaire (MHQ), Purdue Pegboard Test or Nine-Hole Peg Test, Hand Dynamometer Test and Sustained Grip Test.

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Female badminton athletes
  • Age between 18-30 years
  • Right-hand dominant

Treatment and study plan

Isometric hand strengthening program

Other

Participants in this group will receive a structured targeted isometric hand strengthening program performed three sessions per week for six weeks

Isotonic hand strengthening program

Other

Participants in this group will receive a structured isotonic hand strengthening program performed three sessions per week for six weeks

Primary outcomes

  1. Hand Dexterity

    Time frame: Baseline, Week 3, Week 6

    Hand dexterity will be assessed using the Purdue Pegboard Test / Nine-Hole Peg Test to evaluate fine motor coordination and manual dexterity required for sport-specific hand movements.

  2. Grip Strength

    Time frame: Baseline, Week 3, Week 6

    Grip strength will be measured using a calibrated hand dynamometer to assess maximal voluntary isometric contraction of the dominant hand.

  3. Grip Endurance

    Time frame: Baseline, Week 3, Week 6

    Grip endurance will be assessed using the Sustained Grip Strength Test by measuring the duration for which participants can maintain 50% of their maximal voluntary contraction.
