Effects of a 3 month endurance training programme on skeletal muscle histochemistry in Andalusian, Arabian and Anglo-Arabian horses.
Abstract: Twenty adult (5 to 14 years old) sedentary stallions of several breeds (8 Andalusians, 7 Arabians and 5 Anglo-Arabians) were endurance-trained for 3 months. Duplicate biopsies from 2 different depths (20 mm, superficial sampling site; 60 mm, deep sampling site) of the gluteus medius muscle were collected before and after training and after 3 months of detraining. Few significant changes in muscle fibre type composition were recorded in response to training. The percentage of type I fibres in the deep sampling site of the muscle in Andalusian horses and of type IIB oxidative fibres in the superficial region in Anglo-Arabians had increased significantly (P < 0.05) after training. The mean type I and IIA cross-sectional area was increased significantly (range P < 0.05 to P < 0.01) after 3 months' training in the deep site of the muscle in Arabian and Andalusian horses, but not in Anglo-Arabians. The changes seen in fibre sizes disappeared after the detraining period. The mean number of capillaries adjacent to type I fibres in the superficial sampling site of the muscle had increased significantly (P < 0.05) in response to training in Andalusian and Arabian horses. However, a significant decrease in the mean number of capillaries in contact with each fibre type relative to the mean area of that fibre type was observed associated with training in the deep region of the muscle for type I and IIA fibres in Arabians (P < 0.01) and for type I fibres in Andalusian horses (P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Summary
This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.
This research carried out a study on twenty adult stallions of different breeds (Andalusians, Arabians, and Anglo-Arabians). It investigated how a 3 month-long endurance training program affected the histochemistry of the gluteus medius muscle in these horses, taking biopsies before and after the training, as well as after a 3 month detraining period.
Sample Selection
- The researchers selected twenty stallions aged 5 to 14 years for the study. The breeds were Andalusian, Arabian, and Anglo-Arabian, with 8, 7, and 5 horses selected from each breed respectively.
- The horses were sedentary prior to the experiment, providing a consistent baseline for the study.
Training Program
- The horses underwent an endurance training program lasting for 3 months.
- This was followed by a detraining period, also lasting for 3 months.
Biopsy and Analysis
- Duplicate biopsies were taken from the gluteus medius muscle. One was taken from a depth of 20mm (superficial sampling site), and another from 60mm (deep sampling site). These biopsies were taken both before and after the training and detraining periods.
- The researchers analyzed changes in muscle fibre type composition resulting from the training program.
Findings
- There were few significant changes in the muscle fibre type composition in response to the training program. However, an increase in type I fibres in Andalusian horses and type IIB oxidative fibres in Anglo-Arabians was noted.
- The cross-sectional area of type I and IIA fibres increased significantly post-training for Arabian and Andalusian horses, but not for Anglo-Arabians. These changes disappeared after the detraining period.
- The mean number of capillaries adjacent to type I fibres increased for Andalusian and Arabian horses, indicating a response to training.
- However, there was a decrease in capillaries in contact with each fibre type relative to the fibre’s mean area with training, noted particularly for type I and IIA fibres in Arabians and type I fibres in Andalusians.
