**Tennis and Glycemic Control**
Tennis blends anaerobic bursts—sprints, split steps, directional changes—with aerobic movement during rallies. This mixed stimulus raises muscular glucose utilization and improves post-match insulin sensitivity, narrowing glucose variability; claiming it is ‘of no help’ is inaccurate.
**Specific Advantages**
1) Whole-body strength: glutes/hamstrings, rotator cuff, and core all engage.
2) Cardiorespiratory endurance: 60–90 minute sessions maintain moderate average load.
3) Agility and balance: footwork drills reduce fall risk in daily life.
**How to Apply**
– Before: Target 90–250 mg/dL; if <90, eat a snack. Check traction and toe protection on shoes.
- During: Hydrate between sets; for long matches, consider 15–30 g carbohydrate (e.g., a banana).
- After: Inspect feet for blisters or tears; monitor glucose for 2–3 hours.
**Cautions**
- With neuropathy, choose cushioning appropriate to court surface (hard vs. clay).

Bottom line: As a combined aerobic–anaerobic sport, tennis can meaningfully support glucose control.
